    A woman had difficulties in word finding since age 59, this became a Broca's aphasia then a global aphasia. The only possible expression was written and agrammatic with many semantic errors. Calculation was preserved as well as constructional praxis. Ideomotor praxis was slightly impaired. Visual recognition and somatagnosia were normal. Neurological examination showed neither motor nor sensitive impairment. Visual fields were normal. CT scan at onset was normal. Later a slight cortical atrophy appeared predominating on the sylvian fissures, slightly more severe on the left side. Reviewing the literature the authors draw attention on the possible occurrence of an evolutive aphasia being the first evidence of a dementia. The impairment of the other cognitive functions would only appear after several years.

    Language disorders of degenerative origin are frequently tied to Alzheimer disease (AD) the different variants of which can result in primary and secondary aphasia syndromes. More specifically, Alzheimer pathology can primarily erode frontal, temporal or parietal language cortices resulting in three genuine AD language variants which account for about 30% of primary degenerative aphasias. Likewise, it can spread from non-language to language cortices leading to secondary language disorders like in typical amnesic AD and in several atypical AD variants. This paper reviews the whole set of AD variants by characterising their impact on the neural language system and on linguistic functioning. It also provides cues for diagnostic strategies which are essential for linguistic, syndromic and nosological patient classification, for adequate clinical follow-up and for guiding language rehabilitation. Such diagnostic approaches, founded on detailed linguistic phenotyping while integrating anatomical and neuropathological findings, also represent a crucial issue for future drug trials targeting the physio-pathological processes in degenerative aphasias.

    Quarrels over aphasia are no recent phenomena and have not always been explicit. Lordat and Gall can be cited in this respect as well as Dax and Bouillaud. Reference is also made to Broca-Dax and Trousseau-Lordat. The creation of the Chair in honour of Charcot, which contributed so greatly (thanks to Charcot himself, the others Masters and their students) to the birth of neurology, then to that of the neurological sciences and eventually to that of the neurocognitive sciences. Next, the most explicit of quarrels on aphasia is dealt with, namely that in which, during three meetings of the French Society of Neurology in 1908, Joseph Jules Dejerine and Pierre Marie crossed swords. Their duel in the Bois de Boulogne in 1893 having fortunately been cancelled, it was in 1908 merely a battle of words. Fulgence Raymond was soon to retire. Dejerine and Pierre Marie each put forward their proposal to the Society for a discussion program and Dejerine's was accepted following a vote. The meeting on 11th June, in accordance with the program proposed by Dejerine, was largely restricted to clinical facts. Fulgence Raymond was not present. Dejerine always spoke first, but some of the replies from Pierre Marie received a degree of approval from the audience. It was during this meeting that Achille Souques, the future founder of the history of neurology, cleverly defended the ideas of Pierre Marie. A little later, Dejerine went on the defensive and agreed to a change in the program along the lines suggested by Pierre Marie: he then presented his ideas on the manifest clinical difference between Broca's aphasia and that of Wernicke. After Souques, Edouard Brissaud also came to the rescue of Pierre Marie by mentioning the Leborgne case published by Broca in the spring 1861. Matters were unresolved and André-Thomas, the future founder of neuropaediatrics, produced a highly intelligent deference of his Master Dejerine. Gilbert Ballet and Ernest Dupré also came down largely on his side

  7. [Dominant Thalamus and Aphasia].

    Many studies have shown that lesions of the dominant thalamus precipitate language disorders in a similar manner to transcortical aphasias, in a phenomenon known as "thalamic aphasia." In some cases, however, aphasia may not occur or may appear transiently following thalamic lesions. Furthermore, dominant thalamic lesions can produce changes in character, as observed in patients with amnesic disorder. Previous work has explored the utility of thalamic aphasia as a discriminative feature for classification of aphasia. Although the thalamus may be involved in the function of the brainstem reticular activating system and play a role in attentional network and in memory of Papez circuit or Yakovlev circuit, the mechanism by which thalamic lesion leads to the emergence of aphasic disorders is unclear. In this review, we we survey historical and recent literature on thalamic aphasia in an attempt to understand the neural processes affected by thalamic lesions.

    This study examined discourse characteristics of individuals with aphasia who scored at or above the 93.8 cutoff on the Aphasia Quotient subtests of the Western Aphasia Battery-Revised (WAB-R; Kertesz, 2007). They were compared with participants without aphasia and those with anomic aphasia. Participants were from the AphasiaBank database and included 28 participants who were not aphasic by WAB-R score (NABW), 92 participants with anomic aphasia, and 177 controls. Cinderella narratives were analyzed using the Computerized Language Analysis programs (MacWhinney, 2000). Outcome measures were words per minute, percent word errors, lexical diversity using the moving average type-token ratio (Covington, 2007b), main concept production, number of utterances, mean length of utterance, and proposition density. Results showed that the NABW group was significantly different from the controls on all measures except MLU and proposition density. These individuals were compared to participants without aphasia and those with anomic aphasia. Individuals with aphasia who score above the WAB-R Aphasia Quotient cutoff demonstrate discourse impairments that warrant both treatment and special attention in the research literature.

    Aphasia is one of the most striking cognitive sequels of strokes and other cerebral lesions, and attempts to rehabilitate aphasic patients have been undertaken for many years. Following a brief overview of the epidemiology and the clinical characteristics of aphasia, the chapter presents the major traditional approaches to rehabilitation. They include the stimulation approach (also called classic), the behavior modification approach, Luria's approach (functional reorganization), the pragmatic approach, as well as the neurolinguistic approach. The next section illustrates some of the current approaches to aphasia rehabilitation, specifically the syndromic approach (also called neoassociationist), the cognitive neuropsychological approach, and the social approach. The chapter then provides examples of specific methods. While all intervention strategies may be classified, more or less correctly, into one or another of the above categories, it is not possible to mention the hundreds of specific interventions to be found in the literature, some of which have been described only briefly and in reference to a single case. The chapter concludes with a review of efficacy studies on aphasia therapy. Despite some opinions to the contrary, the current consensus is that sufficient experimental evidence of efficacy exists to recommend treatment of aphasia. Copyright © 2013 Elsevier B.V.

    Acute aphasia is rare in multiple sclerosis. We describe 3 patients with multiple sclerosis who had acute exacerbations presenting as aphasias. One patient had a mixed transcortical aphasia, 1 had a transcortical motor aphasia, and 1 had a Broca aphasia. Magnetic resonance imaging scans of the brain with contrast enhancement revealed new white matter lesions in the left hemisphere in all 3 patients. Two of the 3 patients had a good response to treatment with methylprednisolone sodium succinate. Arch Neurol. 2000;57:1207-1209

    The sequelae of post-stroke aphasia are considerable, with implications at the societal and personal levels. An understanding of the mechanisms of recovery of cognitive and language processes after stroke and the factors associated with increased risk of post-stroke language and cognitive deficits is vital in providing optimal care of individuals with aphasia and in counseling to their families and caregivers. Advances in neuroimaging facilitate the identification of dysfunctional or damaged brain tissue responsible for these cognitive/language deficits and contribute insights regarding the functional neuroanatomy of language. Evidence-based person-centered behavioral therapy remains the mainstay for rehabilitation of aphasia, although emerging evidence shows that neuromodulation is a promising adjunct to traditional therapy. These topics are discussed in this review, illustrating with recent studies from the Stroke Cognitive Outcomes and REcovery (SCORE) lab.

    Approximately 400,000 years ago men started to use language. Initially it was probably poor with few phonemes. With social evolution it became more complex, with the appearance of new phonemes and a more complete grammatical structure. The current concept of the processing of language dates, with little change, from the nineteenth century. With the birth of phrenology language began to be studied. This lead to the hypothesis of Wernicke, with two main areas joined by the fasciculo arcuato, which is still held to be valid with modifications by Gerchwind and Damasio, amongst others. Important advances in the study of language are due to Chomsky and his transformational grammar. This supports the universal structure of language, since one learns it following genetically determined laws. Language has three main aspects: creativity which makes both the transmitter and the receiver active participants in communication, the form from which words are constructed and the content of the message. Aphasia is an alteration in the comprehension and understanding of language, which may be the clinical expression of many different aetiologies. They help us to localize the lesion topographically. They are divided depending on the clinical signs, into motor or Broca's aphasia, in which understanding is conserved but the patient uses a language with poor grammatical structure, although the semantic content is acceptable: sensitive or Wernicke's aphasia, with inability to understand and language which is fluid but unintelligible; conduction aphasia due to limitation in the transmission of impulses from Wernicke's area to that of Broca, with acceptable understanding and fluid language and the trans-cortical aphasias where the main characteristic is indemnity of the capacity of repetition. The aphasias, as the expression of an alteration of language are an important support in the topographical localization of lesions, even before these can be shown on computerized tomography.

  16. Frontal-opercular aphasia.

    1999-11-01

    The standard nomenclature divides nonfluent aphasic syndromes with relatively spared comprehension into Broca's aphasia and transcortical motor aphasia. We report on a patient with a persistent nonfluent aphasia from a discrete, primarily cortical, frontal-opercular lesion who had impaired syntax but intact repetition and, therefore, did not conform to the traditional classification. Based on this patient's behavior and a review of other cases, we have divided the nonfluent aphasias with intact comprehension into five disorders. (1) Verbal akinesia-exhibiting diminished intention or drive to speak and associated with medial frontal lesions (supplementary motor area and cingulate gyrus) or with lesions damaging the efferent projections from these areas. (2) Disorders of syntax-telegraphic and agrammatic utterances that may be associated with dominant pars opercularis lesions. (3) Phonemic disintegration-a failure to correctly produce phonemes, which may be associated with injury to the opercular primary motor cortex or efferent projections from this area. (4) Defects of lexical access-patients who struggle to find words and are impaired at timed word-generation tasks. Defects of lexical access may be associated with lesions of the pars triangularis and adjacent prefrontal cortex. (5) Mixed defects. According to this model, the traditional patient with Broca's aphasia would exhibit disorders of syntax, phonemic disintegration, and defects of lexical access, whereas the traditional patient with transcortical motor aphasia would have verbal akinesia or defects of lexical access or both. Our patient had defects of lexical access and syntax, but only mild symptoms of phonemic disintegration, suggesting that his opercular primary motor cortex was relatively intact. Our patient's ability to repeat normally while his propositional speech remained telegraphic suggests that different neural mechanisms subserve these functions. Copyright 1999 Academic Press.

    1987-03-01

    Three patients acutely developed global aphasia, but did not manifest the typical accompanying right hemiparesis. Computed tomography and magnetic resonance imaging studies demonstrated that the patients had two discrete left hemisphere lesions, one in the anterior language cortices or language-related subcortical areas, and one in the posterior language cortices. Cerebral angiography showed that two patients had complete occlusion of the left internal carotid artery, and the third had an intraluminal "clot" in the supraclinoid portion of the left internal carotid, findings suggestive of an embolic etiology. Our cases indicate that global aphasia without hemiparesis predicts two discrete lesions and a particularly good recovery of speech and language.

    Patients with jargon aphasia generally have fluent speech with poor comprehension. However, outstanding jargons may appear in non-fluent aphasics. We report a 69-year-old left-handed woman with non-fluent jargon aphasia due to lesions in the right frontoparietal area. Features of her speech included non-fluent meaningless sequences of syllables, i. e., phonetic jargon, which was obvious in all the tasks including spontaneous speech, repetition, naming and reading. Her utterance was sparse, but not effortful or anarthric. She understood most of spoken single words, but was confused by complex sentences. Brain CTs revealed acute lesions affecting the inferior and middle frontal gyri, insular cortex, precentral and postcentral gyri, and a part of the angular gyrus in the right hemisphere. Old infarcts were also noted in the right frontal pole and prefrontal area. The unique feature of her language impairment suggested somewhat deviated lateralization and localization of her language function.

    An artist active drawing and waterpainting, most prominent in sculpture, suffered an apopleptic insult at 66 years of age. Right hemiparesis and severe motor aphasia remained but this with rare unexpected and sometimes rather complicated productions in spoken, and also in written language in spite of modest progress in writing exercise. His behaviour witnessed of the memory of remote and complicated stored material. Some months after the insult he resumed his artistic activity using his left hand and continued it principally in the same manner as before his illness. His drawing and water-painting displayed some uncertainty of lines and sometimes coarseness of the stain spots. His pieces of sculpture regained the quality of his earlier works, as proven already by the first statue he made after the insult. While it is generally accepted that the motor aphasia does not essentially affect the artistic production, even of high quality, in painting, this is the first instance which proves that the same holds true for sculpture. In this case the mechanisms inciting the finest innervation on the side of the cortical center of the left hand, can work with promptness. In motor aphasia the mechanisms indispensable for the correct realisation of the function are affected without a final extinction of the function itself. Motor asphasia is an instrumental disorder not necessarily accompanied by disturbances of the intelligence.

    Aphasia is an acquired communication disorder that often involves receptive language abilities. After clinical assessment it is often not clear if this is partially due to a hearing loss, which can be compensated by hearing aids facilitating the rehabilitative process.In the present study the hearing ability of 88 male and female patients with aphasia after stroke, all of whom suffered from a left-hemispheric ischemia was assessed in the rehabilitative setting.We found that a majority of patients (72, 82%) was able to perform pure tone audiometry. 15 aphasic patients (21%) showed a hearing loss and were not fitted with hearing aids.Patients with aphasia are due to their central speech disorders in their communication skills limited, so that the therapeutic success is further reduced by an existing hearing loss. Due to the demographic development of our people and with the age increasing prevalence of hearing impairment hearing screening in the post-acute phase in aphasic patients is justified by pure tone audiometry. © Georg Thieme Verlag KG Stuttgart · New York.

    2013-01-01

    Background The dopaminergic system is involved in a wide range of cognitive functions including motor control, reward, memory, attention, problem-solving and learning. This has stimulated interest in investigating the potential of dopaminergic drugs as cognitive enhancers in aphasic patients. Aim To discuss the evidence for the use of dopaminergic agents in patients with aphasia. Levodopa (L-dopa) and the dopamine agonist bromocriptine are the two drugs that have been trialled to date. We discuss, in some detail, the 15 studies that have been published on this topic from the first case report in 1988 to the present (2012), and assess the evidence from each. Main contribution In addition to summarising the effectiveness of the drugs that have been tried, we examine the possible cognitive mechanisms by which dopaminergic drugs may act on language function and aphasia recovery. Given the wide range of dopaminergic drugs, it is surprising that such a narrow range has been trialled in aphasic patients. Important lessons are to be learned from published studies and we discuss optimal trial designs to help guide future work. Conclusions The evidence for the efficacy of dopaminergic agents in aphasia therapy is mixed. Further trials with better tolerated agents are required. Optimal trial designs with appropriate control groups or blocks should be used. The mechanism of action is unclear, but at the cognitive level the evidence points towards either (re)learning of word-forms or their improved retrieval. PMID:25076804

    Aphasia is an important stroke sequel that impacts negatively on the HQoL of stroke patients. Although a number of stroke patients with aphasia will have good functional recovery, many are left with language deficits. Papers were identified through PubMed and MEDLINE search, with keywords such as: 'stroke', 'aphasia', 'post-stroke aphasia', 'factors that predict aphasia recovery', 'aphasia outcomes' and 'aphasia prognosis'. The most important factors that determine recovery are the lesion location and size, aphasia type and severity and to some extent the nature of early haemodynamic response, and treatment received. Anagraphic factors like gender, age, handedness and education have not been found to be robust predictors of recovery. Predicting post-stroke aphasia recovery is difficult, because of the interplay between lesion, anagraphic, and treatment-related factors, in addition to the role of neuroplasticity.

    Aphasia is a speech disorder caused by disorders of speech centre in brain cortex. Patient with aphasia compensates communication disorders by communication strategy, witch are spontaneous mechanisms, and uses individual rehabilitation methods. Compensation mechanisms are divided in to: phonetic, inflective, formative, semantic, discursive and structural. Patients with aphasia early therapy have to be individual and consists in not only articulation correction, but in establish over verbal contact or verbal, and improvement this contacts, to create patients ability of communication with society. Later therapy is oriented on improvement of cognitive functions for possibility of participation in social live and if it is possible for return to work.

    Postictal aphasia has been described in left temporal lobe seizures. It may be of fluent, non-fluent or global type. We present here a patient who displayed signs of mixed transcortical aphasia (MTCA). The patient was a 67 year old man who underwent excision of a left frontal parasagittal meningioma in 1987. Since then he has been treated with phenytoin for generalized tonic-clonic seizures (GTCS). He was admitted in status epilepticus. On awakening, the patient was non-fluent with palilalia and echolalia. His repetition was relatively preserved but all the other language functions were impaired. This picture faded away within a few hours. Brain CT, performed during this postictal state, was normal except for signs related to frontal craniotomy. SPECT, which was performed after language functions returned to normal, displayed left frontal, cingular and insular hypoperfusion. The postictal language dysfunction of the patient corresponded to MTCA. Although our case has frontal, he had no other structural lesion that could explain either diffuse ischemia of the left hemisphere or watershed areas secondary to the generalized seizures. The uniqueness of this case is the combination of postictal MTCA with good prognosis. Copyright 2002 BEA Trading Ltd. Published by Elsevier Science Ltd. All rights reserved.

  17. Neologistic jargon aphasia and agraphia in primary progressive aphasia.

    PubMed

    Rohrer, Jonathan D; Rossor, Martin N; Warren, Jason D

    2009-02-15

    The terms 'jargon aphasia' and 'jargon agraphia' describe the production of incomprehensible language containing frequent phonological, semantic or neologistic errors in speech and writing, respectively. Here we describe two patients with primary progressive aphasia (PPA) who produced neologistic jargon either in speech or writing. We suggest that involvement of the posterior superior temporal-inferior parietal region may lead to a disconnection between stored lexical representations and language output pathways leading to aberrant activation of phonemes in neologistic jargon. Parietal lobe involvement is relatively unusual in PPA, perhaps accounting for the comparative rarity of jargon early in the course of these diseases.

    Context: With advances in neuroimaging, traditional views regarding the clinicoanatomic correlation in stroke patients with aphasia are being challenged and it has been observed that lesions at a given cortical or subcortical site may manifest with different aphasia profiles. Aims: To study as to whether there is a strict clinicoanatomical correlation between the type of aphasia and lesion site in patients with first ever stroke. Settings and Design: Observational study, based in a tertiary care center. Materials and Methods: Stroke patient's ≥18 years of age were screened and those with first ever stroke and aphasia were subjected to a detailed stroke workup and language assessment using the Hindi version of Western Aphasia Battery (WAB). Statistical analysis was done with χ2 test with Yates correction and Kruskal-Wallis test. The level of significance was set at P < 0.05. Results: Overall aphasia was detected in 27.9% of the 260 screened cases with stroke. Amongst 60 cases with first ever stroke and aphasia, the aphasia type was: Global (33.33%), Broca's (28.3%), transcortical motor (13.33%), transcortical sensory (10%), Wernicke's (8.33%), anomic (5%), and conduction (1.67%) aphasia. A definite correlation between the lesion site and the type of aphasia as per the traditional classification was observed in 35% cases only. Conclusions: No absolute correlation exists between the lesion site and the type of clinical aphasia syndrome in majority of the patients with cortical and subcortical stroke. PMID:26713015

    Optic aphasia is a rare syndrome in which patients are unable to name visually presented objects but have no difficulty in naming those objects on tactile or verbal presentation. We report a 79-year-old man who exhibited anomic aphasia after a left posterior cerebral artery territory infarction. His naming ability was intact on tactile and verbal semantic presentation. The results of the systematic assessment of visual processing of objects and letters indicated that he had optic aphasia with mixed features of visual associative agnosia. Interestingly, although he had difficulty reading Hanja (an ideogram), he could point to Hanja letters on verbal description of their meaning, suggesting that the processes of recognizing objects and Hanja share a common mechanism.

    To determine the relations between post-stroke aphasia severity and aphasia type and lesion location, a retrospective review was undertaken using the medical records of 97 Korean patients, treated within 90 days of onset, for aphasia caused by unilateral left hemispheric stroke. Types of aphasia were classified according to the validated Korean version of the Western Aphasia Battery (K-WAB), and severities of aphasia were quantified using WAB Aphasia Quotients (AQ). Lesion locations were classified as cortical or subcortical, and were determined by magnetic resonance imaging. Two-step cluster analysis was performed using AQ values to classify aphasia severity by aphasia type and lesion location. Cluster analysis resulted in four severity clusters: 1) mild; anomic type, 2) moderate; Wernicke's, transcortical motor, transcortical sensory, conduction, and mixed transcortical types, 3) moderately severe; Broca's aphasia, and 4) severe; global aphasia, and also in three lesion location clusters: 1) mild; subcortical 2) moderate; cortical lesions involving Broca's and/or Wernicke's areas, and 3) severe; insular and cortical lesions not in Broca's or Wernicke's areas. These results revealed that within 3 months of stroke, global aphasia was the more severely affected type and cortical lesions were more likely to affect language function than subcortical lesions.

    2011-08-01

    There is a growing trend toward dedicated programs designed to improve the lives of people with aphasia and their families. We are referring to these programs collectively as "aphasia centers." These programs purportedly differ from more traditional medically based aphasia rehabilitation. However, there is no directory of aphasia centers and no definition of what constitutes such a program. Therefore, an online survey was designed to identify and describe aphasia centers in the United States and Canada. A 37-question survey was posted online via SurveyMonkey. An introductory letter was distributed by electronic mail to a listserv and mailing lists of programs associated with aphasia. Potential respondents who considered themselves an aphasia center were asked to complete the survey. A total of 33 survey responses were analyzed, and descriptive data were compiled resulting in a description of the following aspects of aphasia centers: demographic information, mission, admission and discharge policies, assessment practices, program logistics, staffing patterns, marketing, funding, and services offered. In addition, a qualitative analysis of written text responses revealed the following key themes that appear to characterize the responding programs: services that differ from traditional aphasia rehabilitation; a sense of community; a holistic focus on quality of life, psychosocial well-being, participation, and social support; the centrality of group interaction; and variety/intensity of services.

    Computers and related technology can increase the amount of treatment received by adults with chronic aphasia. Computers used in treatment, however, are only valuable to the patient if the intervention is efficacious. Real and potential applications of computer technology are discussed in the context of three roles of computerized aphasia treatment for adults with chronic aphasia. Pertinent studies regarding Phases 1 and 2 are briefly described. The only Phase 3 study of efficacy of computerized aphasia treatment is more fully described and its implications discussed.

    Individuals with aphasia face significant challenges in their lives. These challenges stem from the difficulties caused by impaired language function. Impairment in the ability to successfully communicate could be a significant source of stress to individuals with aphasia. The purpose of the current paper is to present a review of the literature on the neuropsychobiology of stress and aphasia, give a contemporary conceptualization of stress (both neurobiological and psychological), offer a framework and directions for future investigations in stress and aphasia, and finally suggest clinical implications for this line of inquiry.

    2011-12-01

    Borderzone infarcts (BZIs) are anatomically defined as ischemic lesions occurring at the junction between two arterial territories, accounting for 2% to 10% of strokes. Three types of hemispheric BZIs are described according to topography (ie, superficial anterior, posterior, and deep). Although published series on related aphasia are rare in the setting of BZI, aphasia is of transcortical (TCA) type, characterized by the preservation of repetition. TCA can be of motor, sensory, or mixed type depending on whether expression, understanding, or both are impaired. Recent studies have reported specific aphasic patterns. BZI patients initially presented with mixed TCA. Aphasia specifically evolved according to the stroke location, toward motor or sensory TCA in patients with respectively anterior or posterior BZI. TCA was associated with good long-term prognosis. This specific aphasic pattern is interesting in clinical practice because it prompts the suspicion of a BZI before the MRI is done, and it helps in the planning of rehabilitation and in providing adapted information to the patient and family concerning the likelihood of language recovery.

  1. The relationship of aphasia type and gesture production in people with aphasia.

    2013-11-01

    For many individuals with aphasia, gestures form a vital component of message transfer and are the target of speech-language pathology intervention. What remains unclear are the participant variables that predict successful outcomes from gesture treatments. The authors examined the gesture production of a large number of individuals with aphasia-in a consistent discourse sampling condition and with a detailed gesture coding system-to determine patterns of gesture production associated with specific types of aphasia. The authors analyzed story retell samples from AphasiaBank (TalkBank, n.d.), gathered from 98 individuals with aphasia resulting from stroke and 64 typical controls. Twelve gesture types were coded. Descriptive statistics were used to describe the patterns of gesture production. Possible significant differences in production patterns according to aphasia type were examined using a series of chi-square, Fisher exact, and logistic regression statistics. A significantly higher proportion of individuals with aphasia gestured as compared to typical controls, and for many individuals with aphasia, this gesture was iconic and was capable of communicative load. Aphasia type impacted significantly on gesture type in specific identified patterns, detailed here. These type-specific patterns suggest the opportunity for gestures as targets of aphasia therapy.

    Background Persons with aphasia often report feeling anxious when using language while communicating. While many patients, caregivers, clinicians and researchers would agree that language may be a stressor for persons with aphasia, systematic empirical studies of stress and/or anxiety in aphasia remain scarce. Aim The aim of this paper is to review the existing literature discussing language as a stressor in aphasia, identify key issues, highlight important gaps, and propose a program for future study. In doing so, we hope to underscore the importance of understanding aspects of the emotional aftermath of aphasia, which plays a critical role in the process of recovery and rehabilitation. Main Contribution Post stroke emotional dysregulation in persons with chronic aphasia clearly has adverse effects for language performance and prospects of recovery. However, the specific role anxiety might play in aphasia has yet to be determined. As a starting point, we propose to view language in aphasia as a stressor, linked to an emotional state we term “linguistic anxiety.” Specifically, a person with linguistic anxiety is one in whom the deliberate, effortful production of language involves anticipation of an error, with the imminence of linguistic failure serving as the threat. Since anticipation is psychologically linked to anxiety and also plays an important role in the allostatic system, we suggest that examining physiologic stress responses in persons with aphasia when they are asked to perform a linguistic task would be a productive tool for assessing the potential relation of stress to “linguistic anxiety.” Conclusion Exploring the putative relationship between anxiety and language in aphasia, through the study of physiologic stress responses, could establish a platform for investigating language changes in the brain in other clinical populations, such as in individuals with Alzheimer’s disease or persons with post traumatic stress disorder, or even with

    To determine the independent effects of aphasia on outcomes during acute stroke admission, controlling for total NIH Stroke Scale (NIHSS) scores and loss of consciousness. Data from the Tulane Stroke Registry were used from July 2008 to December 2014 for patient demographics, NIHSS scores, length of stay (LOS), complications (sepsis, deep vein thrombosis), and discharge modified Rankin Scale (mRS) score. Aphasia was defined as a score >1 on question 9 on the NIHSS on admission and hemiparesis as >1 on questions 5 or 6. Among 1,847 patients, 866 (46%) had aphasia on admission. Adjusting for NIHSS score and inpatient complications, those with aphasia had a 1.22 day longer LOS than those without aphasia, whereas those with hemiparesis (n = 1,225) did not have any increased LOS compared to those without hemiparesis. Those with aphasia had greater odds of having a complication (odds ratio [OR] 1.44, confidence interval [CI] 1.07-1.93, p = 0.0174) than those without aphasia, which was equivalent to those having hemiparesis (OR 1.47, CI 1.09-1.99, p = 0.0137). Controlling for NIHSS scores, aphasia patients had higher odds of discharge mRS 3-6 (OR 1.42 vs 1.15). Aphasia is independently associated with increased LOS and complications during the acute stroke admission, adding $2.16 billion annually to US acute stroke care. The presence of aphasia was more likely to produce a poor functional outcome than hemiparesis. These data suggest that further research is necessary to determine whether establishing adaptive communication skills can mitigate its consequences in the acute stroke setting. © 2016 American Academy of Neurology.

    We reported two cases of aphasia that exhibited different characteristics of aphasia following cerebral hemorrhage in the left frontal lobe involving the Broca's area. Case 1 is a 74-year-old right-handed woman. She was hospitalized with speech disturbance. Spontanoues speech was fluent and articulation was normal, but she showed verbal paraphasia and speech perseveration. She demonstrated a preserved ability to repeat short sentences and was able to read words aloud. This type of aphasia is called "Broca area's aphasia". MRI and CT showed hematoma involving the left inferior frontal lobe, operculum and insula cortex. Single-photon emission computed tomography (SPECT) showed low perfusion in the frontal lobe without involvement of the postcentral gyrus. Case 2 is a 76-year-old right-handed man. He was also hospitalized with speech disturbance. Spontanoues speech was non-fluent and articulation was poor. He sometimes showed phonemic paraphasia with anarthria, but he demonstrated a preserved ability to repeat short sentences. He was able to read words aloud in a manner comparatively similar to. This type of aphasia is called "Broca's aphasia". MRI and CT showed hematoma involving the left inferior frontal lobe, operculum and precentral cortex. SPECT revealed low perfusion in the frontal lobe extending to the postcentral gyrus. We supposed that the different characteristics of aphasia in those cases were due to extended lesion in the frontal lobe.

    PubMed Central

    2009-01-01

    The terms ‘jargon aphasia’ and ‘jargon agraphia’ describe the production of incomprehensible language containing frequent phonological, semantic or neologistic errors in speech and writing, respectively. Here we describe two patients with primary progressive aphasia (PPA) who produced neologistic jargon either in speech or writing. We suggest that involvement of the posterior superior temporal–inferior parietal region may lead to a disconnection between stored lexical representations and language output pathways leading to aberrant activation of phonemes in neologistic jargon. Parietal lobe involvement is relatively unusual in PPA, perhaps accounting for the comparative rarity of jargon early in the course of these diseases. PMID:19033077

    Comprehension deficits are common in stroke aphasia, including in cases with (i) semantic aphasia, characterized by poor executive control of semantic processing across verbal and non-verbal modalities; and (ii) Wernicke's aphasia, associated with poor auditory-verbal comprehension and repetition, plus fluent speech with jargon. However, the varieties of these comprehension problems, and their underlying causes, are not well understood. Both patient groups exhibit some type of semantic 'access' deficit, as opposed to the 'storage' deficits observed in semantic dementia. Nevertheless, existing descriptions suggest that these patients might have different varieties of 'access' impairment-related to difficulty resolving competition (in semantic aphasia) versus initial activation of concepts from sensory inputs (in Wernicke's aphasia). We used a case series design to compare patients with Wernicke's aphasia and those with semantic aphasia on Warrington's paradigmatic assessment of semantic 'access' deficits. In these verbal and non-verbal matching tasks, a small set of semantically-related items are repeatedly presented over several cycles so that the target on one trial becomes a distractor on another (building up interference and eliciting semantic 'blocking' effects). Patients with Wernicke's aphasia and semantic aphasia were distinguished according to lesion location in the temporal cortex, but in each group, some individuals had additional prefrontal damage. Both of these aspects of lesion variability-one that mapped onto classical 'syndromes' and one that did not-predicted aspects of the semantic 'access' deficit. Both semantic aphasia and Wernicke's aphasia cases showed multimodal semantic impairment, although as expected, the Wernicke's aphasia group showed greater deficits on auditory-verbal than picture judgements. Distribution of damage in the temporal lobe was crucial for predicting the initially 'beneficial' effects of stimulus repetition: cases with

    Communication confidence is a construct that has not been explored in the aphasia literature. Recently, national and international organizations have endorsed broader assessment methods that address quality of life and include participation, activity, and impairment domains as well as psychosocial areas. Individuals with aphasia encounter difficulties in all these areas on a daily basis in living with a communication disorder. Improvements are often reflected in narratives that are not typically included in standard assessments. This article illustrates how a new instrument measuring communication confidence might fit into a broad assessment framework and discusses the interaction of communication confidence, autonomy, and self-determination for individuals living with aphasia.

    2001-01-01

    This paper reviews some different meanings of the term 'psychosocial' and identifies the different ways in which the social and psychological sequelae of aphasia can be explored. These include qualitative methods, which seem well suited to addressing such complex issues. Having outlined some features of qualitative research, the paper describes a study in which fifty people talked about the consequences and significance of their long-term aphasia. Their 'insider perspective' on aphasia suggests its impacts are extensive, complex, direct and indirect, interconnected, systemic, dynamic and diversely experienced. The paper discusses the various implications of the study for clinicians and researchers concerned with the psychosocial aspects of aphasia and outlines how some of the issues raised in the interviews might be addressed.

    Thirty right-handed left hemisphere-damaged patients were taken and divided into five groups (transcortical motor, Broca, conduction, Wernicke, and anomic aphasia). Language deviations were scored and analyzed for the Picture Description (Plate No. 1, The Cookie Theft), Repetition (Words, High and Low Probability Sentences), and Naming (Responsive Naming, Confrontation, and Body-part naming) subtests of the Boston Diagnostic Aphasia Examination--Spanish version (Goodglass & Kaplan, 1979). A classification of paraphasias is proposed. Language deviations were scores for the following groups: Literal paraphasias (phoneme omissions, additions, displacements, and substitutions), verbal paraphasias (formal, morphologic, semantic, and unrelated), syntagmatic paraphasias, circumlocutions (object description and instrumental function), indefinite anaphors, and neologisms. Frequency of different types of language deviations is presented in the five aphasia groups. It was found that some paraphasic errors appeared in several aphasia groups; others were characteristics of specific aphasic syndromes.

  13. Transcortical mixed aphasia with left frontoparietal lesions.

    We present a case of transcortical mixed aphasia following a left frontoparietal infarct caused by vasospasm after subarachnoid haemorrhage. Although CT showed low-density areas in the left frontal lobe and basal ganglia, single photon emission CT revealed a wider area of low perfusion over the entire left hemisphere, except for the left perisylvian speech areas. Hence, transcortical mixed aphasia may be caused by the isolation of perisylvian speech areas due to disconnection from surrounding areas.

    Acupuncture has often been used for aphasia rehabilitation in China. The purpose of this paper was to: 1) provide a historic overview of acupuncture for aphasia due to stroke; 2) summarize the commonly used acupuncture approaches; and 3) objectively comment on the effectiveness of acupuncture for the rehabilitation of this type of disorder. The Elsevier database and a Chinese database (CNKI) were searched through December, 2010 with the key words "aphasia, acupuncture" in English and Chinese, respectively. Case reports, uncontrolled clinical observations and controlled clinical trials were all included if acupuncture was the sole treatment or the main component of complex intervention for the rehabilitation of aphasia caused by cerebrovascular disease. More than 100 relevant articles were found. After analyzing these articles, we found that acupuncture for apoplectic aphasia most often included tongue, scalp, body and combination acupuncture. Tongue bleeding, deep insertion and strong stimulation were adopted by many practitioners. The ten most frequently used acupoints (or areas) were Lianquan (RN 23), Jinjin (EX-HN 12), Yuye (EX-HN 13), Tongli (HT 5), Fengchi (GB 20), Neiguan (PC 6), Baihui (DU 20), No. 1, 2 and 3 language sections, Sanyinjiao (SP 6) and Yamen (DU 15). Controlled clinical studies and a systematic literature review demonstrate that acupuncture has therapeutic effects on aphasia after stroke.

  15. Use of spatial communication in aphasia.

    Spatial communication consists of both verbal spatial language and gesture. There has been minimal research investigating the use of spatial communication, and even less focussing on people with aphasia. The aims of this exploratory study were to describe the frequency and variability of spatial language and gesture use by three participants with aphasia in comparison to nine control participants. This included: 1) frequency of gestures; 2) types of gesture; 3) number of spatial descriptions described by gestures but no language; and 4) frequency and variety of locative prepositional, verb, and noun phrases. Each participant was videoed undertaking 11 spatial communication tasks: four description tasks, and seven tasks involving directing the researcher in the placement of objects or pictures. Gestures and language produced were transcribed and analysed. Participants with aphasia used significantly more gesture. Participants with aphasia also used more gesture without spoken phrases when spatial vocabulary was unavailable. Finally, there were differences between the participants with regards to the types of gesture that they used when they were unable to access language. The results suggest that the analysis of gesture produced by people with aphasia may provide insight into their underlying language impairment. As this was an exploratory study, with just three participants with aphasia, further research is needed. © 2013 Royal College of Speech and Language Therapists.

  16. Neuroscience insights improve neurorehabilitation of poststroke aphasia.

    2011-02-01

    The treatment of aphasias-acquired language disorders-caused by stroke and other neurological conditions has benefitted from insights from neuroscience and neuropsychology. Hebbian mechanisms suggest that massed practice and exploitation of residual neurological capacities can aid neurorehabilitation of patients with poststroke aphasia, and progress in basic neuroscience research indicates that the language system of the human brain is functionally interwoven with perceptual and motor systems. Intensive speech and language therapies, including constraint-induced aphasia therapy, that activate both the linguistic and concordant motor circuits utilize the knowledge gained from these advances in neuroscience research and can lead to surprisingly rapid improvements in language performance, even in patients with chronic aphasia. Drug-based therapies alone and in conjunction with behavioral language therapies also increase language performance in patients with aphasia. Furthermore, noninvasive transcranial magnetic stimulation and electrical stimulation techniques that target neuronal activity within perilesional areas might help patients with aphasia to regain lost language functions. Intensive language-action therapies that lead to rapid improvements in language skills might provide a new opportunity for investigating fast plastic neuronal changes in the areas of the brain associated with language processing. Here, we review progress in basic neuroscience research and its translational impact on the neurorehabilitation of language disorders after stroke.

    Background AphasiaBank is a computerized database of interviews between persons with aphasia (PWAs) and clinicians. By February 2011, the database had grown to include 145 PWAs and 126 controls from 12 sites across the United States. The data and related analysis programs are available free over the web. Aims The overall goal of AphasiaBank is the construction of a system for accumulating and sharing data on language usage by PWAs. To achieve this goal, we have developed a standard elicitation protocol and systematic automatic and manual methods for transcription, coding, and analysis. Methods & Procedures We present sample analyses of transcripts from the retelling of the Cinderella story. These analyses illustrate the application of our methods for the study of phonological, lexical, semantic, morphological, syntactic, temporal, prosodic, gestural, and discourse features. Main Contribution AphasiaBank will allow researchers access to a large, shared database that can facilitate hypothesis testing and increase methodological replicability, precision, and transparency. Conclusions AphasiaBank will provide researchers with an important new tool in the study of aphasia. PMID:22923879

    Purpose This article describes computer software that was developed specifically for training conversational scripts and illustrates its use with three individuals with aphasia. Methods Three participants with chronic aphasia (Broca’s, Wernicke’s and anomic) were assessed before and after nine weeks of a computer script training program. For each participant, three individualized scripts were developed, recorded on the software, and practiced sequentially at home. Weekly meetings with the speech-language pathologist occurred to monitor practice and assess progress. Baseline and post-treatment scripts were audio-taped, transcribed, and compared to the target scripts for content, grammatical productivity and rate of production of script-related words. Interviews with the person with aphasia and their significant other were conducted at the conclusion of treatment. Results All measures (content, grammatical productivity and rate of production of script-related words) improved for each participant on every script. Two participants gained more than five points on the Aphasia Quotient of the Western Aphasia Battery. Five positive themes were consistently identified from the exit interviews - increased verbal communication, improvements in other modalities and situations, communication changes noticed by others, increased confidence, and satisfaction with the software. Conclusion Computer-based script training potentially may be an effective intervention for persons with chronic aphasia. PMID:18230811

    Primary progressive aphasia (PPA) is a neurodegenerative disease that primarily affects language functions and often begins in the fifth or sixth decade of life. The devastating effects on work and home life call for the investigation of treatment alternatives. In this paper, we present a review of the literature on treatment approaches for this neurodegenerative disease. We also present new data from two intervention studies we have conducted, a behavioral one and a neuromodulatory one using transcranial direct current stimulation (tDCS) combined with written production intervention. We show that speech-language intervention improves language outcomes in individuals with PPA; and especially in the short term, tDCS augments generalization and maintenance of positive language outcomes. We also outline current issues and challenges in intervention approaches in PPA. PMID:26062526

  2. Narrative discourse in anomic aphasia.

    Anomic aphasia is a disturbance affecting lexical retrieval. Nonetheless, persons with this disorder may also experience difficulties in the construction of coherent narratives. Whether this symptom is a sign of a macrolinguistic difficulty per se or reflects the lexical disorder is still an open debate. In order to analyze the effect of the lexical impairment on macrolinguistic processing, we compared the narrative skills of a group of ten participants with chronic anomic aphasia with those of ten healthy control individuals matched for age and educational level. The anomic participants produced narratives with lowered speech rate, reduced mean length of utterance, fewer grammatically well-formed sentences, more semantic paraphasias. The macrolinguistic analysis showed that they also produced more errors of cohesion and global coherence and fewer lexical information units. Interestingly, their levels of thematic selection were normal. A bivariate correlational analysis showed a strong correlation between the production of errors of cohesion and production of complete sentences, and between production of errors of global coherence and lexical information units. These correlations showed that aspects related to lexical retrieval may affect macrolinguistic processing during the construction of a narrative. Indeed, it is suggested that lexical deficits lead to two main consequences: First, patients with anomia frequently interrupt the utterances they are producing and this reduces the levels of sentence completeness and the overall degree of cohesion across the utterances; Second, they use strategies to cope with the lexical impairment and produce a quantity of lexical fillers and repetitions that, clustered in utterances, reduce the levels of global coherence.

    2010-01-01

    One of the greatest challenges to language rehabilitation is reconciling the fact that the same therapeutic intervention, provided to different individuals with similar types of stroke-induced aphasia, may result in divergent outcomes. In this paper, the authors reviewed existing literature to identify relevant ambient factors – those outside the control of the clinician – that may potentially influence functional language recovery in aphasia and response to treatment. The goal was to develop a clinical history-taking tool to assist clinicians in gathering information germane to each individual's unique circumstances and environment, elements that may have previously been underestimated, to provide a complete inventory of potentially potent prognostic factors. First, two of the authors, speech–language pathologists experienced in aphasia rehabilitation, identified and categorized factors that seemed likely to influence aphasia outcomes. Then, a wide range of literature was reviewed in an effort to identify factors empirically found to be potent influences on aphasia recovery. Where studies relating these factors to aphasia were not found, relevant research from allied fields that examined recovery from brain injury is reported. Moreover, some factors thought to be potentially potent have yet to be examined. Finally, the ambient factors supported by evidence were categorized as facilitators or barriers to functional improvement, and the Ambient Influences on Outcome Checklist (AOC) was developed, including only those factors shown to be potent in the recovery process. It is hoped that this checklist can be used to more broadly assess potential prognostic influences in aphasia restitution, as well as spawn further research. PMID:21103021

    2013-05-01

    In contrast to clinician-as-expert models, social models of clinical practice typically acknowledge people with aphasia as equal partners in intervention. Given this, there may be a place within speech-language pathology education for programs situating people with aphasia as experts. This paper describes an aphasia mentoring program that was implemented as part of a speech-language pathology graduate program. Qualitative research methods with thematic analysis of interviews, focus groups, questionnaires, and participant observation were used to develop a description of the mentoring program, including the experiences and perspectives of the participants-both mentors (people with chronic aphasia) and students. Five themes, including getting better, aphasia advocacy, group as versus for therapy, we're a team, and focus on mentoring, emerged from the mentors' data. Five themes, including shifting the power dynamic, getting to know the person, seeing members as mentors, making classroom learning real, and connecting with a community, emerged from the students' data. There were significant overlaps and intersections between the 2 data sets. Findings revealed how an aphasia mentoring program that positions people with aphasia as experts can make a significant contribution to student education while supporting mentors' own goals, with implications for improved quality of life.

  12. [Aphasia and related impairments pertaining to FTLD].

    PubMed

    2012-01-01

    FTLD consists of three clinical types: behavioural variant FTD, progressive non-fluent aphasia (PNFA) and semantic dementia (SD). The latter two types manifest aphasia. Thus, it is quite important to pertinently assess the symptoms of aphasia and related impairments for diagnosis of FTLD. The most important point for diagnosis of PNFA is existence of anarthria/apraxia of speech, which is a focal symptom of the left prefrontal gyrus and underlying white matter. With the progression of the disease word generation and comprehension is deteriorating. SD shows Gogi aphasia when the lesion have predilection of left temporal lober atrophy. We investigated 28 patients without any antecedents causing speech/language impairments, who developed primary progressive aphasia. All the patients underwent a routine neurological and neuropsychological examinations and related symptoms such as orofacial apraxia, frontal lobe signs, dysphasia and so on were assessed. The results indicated that 20 patients were diagnosed as PNFA, and they were subdivided into three clinical groups. One group developed naming impairment and orofacial apraxia in several years after onset, and followed with various frontal symptoms. Another group showed anterior opereculum syndromes within two years after onset. The third group retained pure anarthria/apraxia of speech for many years without any other symptoms.

    We describe a brief pilot study undertaken to investigate the potential benefit(s) of using a SenseCam in aphasia therapy. Five post-stroke persons with aphasia and their caregivers agreed to participate. Each person with aphasia wore the SenseCam for 1 day during the daytime. Slide shows and printed images were created from the images obtained and presented at a (videotaped) weekly group conversation session. Therapists' observations, reflections, and opinions were subsequently elicited in a group interview and online survey. Wearable, sensor-triggered automatic imaging devices offer potential advantages over both conventional cameras and generic pictures when used in aphasia therapy. We identified three advantages of a SenseCam over conventional imaging methods: Images can be acquired without the presence of the researcher, no action is required by the wearer for image acquisition and the continuous point of view is that of the wearer. Acquired images are of personal relevance to the wearer and may have greater efficacy for the person with aphasia in aiding conversation, and for the speech language therapist in setting functional language goals.

  14. Stroke rehabilitation using noninvasive cortical stimulation: aphasia.

    PubMed

    Mylius, Veit; Zouari, Hela G; Ayache, Samar S; Farhat, Wassim H; Lefaucheur, Jean-Pascal

    2012-08-01

    Poststroke aphasia results from the lesion of cortical areas involved in the motor production of speech (Broca's aphasia) or in the semantic aspects of language comprehension (Wernicke's aphasia). Such lesions produce an important reorganization of speech/language-specific brain networks due to an imbalance between cortical facilitation and inhibition. In fact, functional recovery is associated with changes in the excitability of the damaged neural structures and their connections. Two main mechanisms are involved in poststroke aphasia recovery: the recruitment of perilesional regions of the left hemisphere in case of small lesion and the acquisition of language processing ability in homotopic areas of the nondominant right hemisphere when left hemispheric language abilities are permanently lost. There is some evidence that noninvasive cortical stimulation, especially when combined with language therapy or other therapeutic approaches, can promote aphasia recovery. Cortical stimulation was mainly used to either increase perilesional excitability or reduce contralesional activity based on the concept of reciprocal inhibition and maladaptive plasticity. However, recent studies also showed some positive effects of the reinforcement of neural activities in the contralateral right hemisphere, based on the potential compensatory role of the nondominant hemisphere in stroke recovery.

    Personal narratives have been suggested as a way for persons post stroke to re-establish their identity. To relate tellable personal stories, narrative competence - along with its building blocks - is essential. The objective of this study was to describe narrative competence in persons with mild to moderate aphasia. It addressed the areas of coherence, clarity, temporal-causal structure, and reference in narratives. The study also examined the strategies used (evaluative language) as well as the topics and themes in personal narratives. Sixteen individuals with mild to moderate aphasia were asked to relate the story of their stroke and stories of a memorable and a frightening experience. Stories were elicited using a "willing listener" procedure. Responses were analyzed quantitatively in terms of the number of propositions and the instances of temporal-causal sequences, reference, and evaluation. Qualitative analysis was performed to determine the overall coherence and clarity of the narratives. Narrative competence was present in the majority of participants. Although difficulties with reference were observed, high ratings of narrative coherence and clarity were attributed to sufficient amount of language, preserved temporal-causal sequencing, and the use of strategies (evaluative language). Narrative competence was exhibited in the personal narratives of individuals with mild to moderate aphasia. In addition to pinpointing essential elements of narrative competence, the use of personal narratives was deemed beneficial for both the clinician, by providing a better understanding of the individual with aphasia, and the individual with aphasia, by providing opportunities for self-disclosure.

    The incidence of cardiovascular disorders and stroke in Australian Aboriginal communities is more than twice as high as non-Indigenous Australians. Approximately 30% of people who survive stroke are left with some level of aphasia, and yet Indigenous Australians appear to be infrequent users of speech-language pathology services, and there is virtually no research literature about the experiences of aphasia for this group of people. This paper presents the stories of living with aphasia for three Indigenous Australian men living in Perth, Western Australia. Their narratives were collected by an Indigenous researcher through in-depth, supported interviews, and were explored using both within-case and cross-case analyses for common and recurring themes. It is argued that there is value for speech-language pathologists, and other health professionals, to be aware of the broad experiences of living with aphasia for Indigenous Australians because their stories are rarely heard and because, as with people with aphasia generally, they are at risk of social isolation and tend to lack visibility in the community. This study explores the key issues which emerge for these three men and highlights the need for further research in this area.

    Aphasia is an acquired neurologic disorder that impairs an individual's ability to use and/or understand language. It commonly occurs after stroke or other injury to the brain's language network. The authors present the current methods of diagnosis and treatment of aphasia. They include a review of the evidence for the benefits of speech-language therapy, the most widespread approach to aphasia treatment, and a discussion of newer interventions such as medication and brain stimulation. These methods hold much promise for improving patient outcomes in aphasia; however, additional research regarding the best approaches to aphasia treatment will greatly improve our clinical approach.

    We report four patients with progressive aphasia of the non-fluent type as the presenting clinical manifestation. The patients were included in a longitudinal study of focal progressive neuropsychological syndromes, and were periodically submitted to neuropsychological evaluations and neuroimaging studies (TC, MRI, SPET or PET). The pattern of neuropsychological impairment was in good agreement with the results of functional imaging studies, which indicated involvement of the anterior regions of the left hemisphere. The evolution of the clinical picture was extremely heterogeneous in the four patients, ranging from a relatively stable picture of transcortical motor aphasia to a severe progressive frontal lobe syndrome. Progressive non-fluent aphasia appears to be a reliable clinical marker of the localization of the pathological process; whether this is related to specific neuropathological conditions, such as Pick's disease, remains for the moment a matter of speculation.

    We report a dissociation between higher order mathematical ability and language in the case of a man (SO) with severe aphasia. Despite severely impaired abilities in the language domain and difficulties with processing both phonological and orthographic number words, he was able to judge the equivalence of and to transform and simplify mathematical expressions in algebraic notation. SO was sensitive to structure-dependent properties of algebraic expressions and displayed considerable capacity to retrieve algebraic facts, rules and principles, and to apply them to novel problems. He demonstrated similar capacity in solving expressions containing either solely numeric or abstract algebraic symbols (e.g., 8-(3-5)+3 versus b-(a-c)+a). The results show the retention of elementary algebra despite severe aphasia and provide evidence for the preservation of symbolic capacity in one modality and hence against the notion of aphasia as asymbolia.

    Pulvermüller, Friedemann; Berthier, Marcelo L.

    2008-01-01

    Background Brain research has documented that the cortical mechanisms for language and action are tightly interwoven and, concurrently, new approaches to language therapy in neurological patients are being developed that implement language training in the context of relevant linguistic and non-linguistic actions, therefore taking advantage of the mutual connections of language and action systems in the brain. A further well-known neuroscience principle is that learning at the neuronal level is driven by correlation; consequently, new approaches to language therapy emphasise massed practice in a short time, thus maximising therapy quantity and frequency and, therefore, correlation at the behavioural and neuronal levels. Learned non-use of unsuccessful actions plays a major role in the chronification of neurological deficits, and behavioural approaches to therapy have therefore employed shaping and other learning techniques to counteract such non-use. Aims Advances in theoretical and experimental neuroscience have important implications for clinical practice. We exemplify this in the domain of aphasia rehabilitation. Main Contribution Whereas classical wisdom had been that aphasia cannot be significantly improved at a chronic stage, we here review evidence that one type of intensive language-action therapy (ILAT)—constraint-induced aphasia therapy—led to significant improvement of language performance in patients with chronic aphasia. We discuss perspectives for further improving speech-language therapy, including drug treatment that may be particularly fruitful when applied in conjunction with behavioural treatment. In a final section we highlight intensive and rapid therapy studies in chronic aphasia as a unique tool for exploring the cortical reorganisation of language. Conclusions We conclude that intensive language action therapy is an efficient tool for improving language functions even at chronic stages of aphasia. Therapy studies using this technique can

    The present case study investigated modality-specific aspects of novel word acquisition in aphasia. It was prompted by recent aphasia case studies indicating great interindividual variability in the ability to learn and maintain novel words in aphasia. Moreover, two previous case studies revealed a striking effect of input modality by showing effective word learning and re-learning via visual input only (Kohen, Sola, Tuomiranta, Laine, & Martin, 2012; Tuomiranta et al., 2014). The present participant TS with chronic nonfluent aphasia and post-semantic anomia was administered novel word–referent learning tasks. In the first experiment, the learning phase included simultaneous phonological and orthographic input, while the follow-up was probed separately for spoken and written responses. In the second experiment, we studied the effect of four different input and output modality combinations on her ability to learn to name the novel items. In the first experiment, TS’s spoken naming performance during the learning phase was just within the range of healthy controls. Maintenance declined and remained outside that range during the whole 6-month follow-up. However, TS maintained the learned words better in written than in spoken naming throughout the follow-up, and in written naming, her maintenance stayed within the control’s range up to 8 weeks post-training. The second experiment indicated that the best learning outcome was achieved with orthographic input. Orthographic input combined with orthographic output resulted in fast and accurate learning of the novel words. Interestingly, TS’s test profile was opposite to her learning profile, as she repeated better than she read aloud in the linguistic background assessment. The results from the present case highlight the importance of multiple learning channels for word acquisition in individuals with aphasia. Probing the functionality of different input and output channels for learning may also prove valuable in

    The aim is to update our clinical recommendations for evidence-based language rehabilitation of people with aphasia, based on a systematic review of the literature from 1999 to 2015. Articles referred to in this systematic review of the Medline and PubMed published in English language literatures were from 1998 to 2015. The terms used in the literature searches were aphasia and evidenced-based. The task force initially identified citations for 51 published articles. Of the 51 articles, 44 studies were selected after further detailed review. Six articles, which were not written in English, and one study related to laryngectomy rehabilitation interventions, were excluded from the study. This study referred to all the important and English literature in full. Aphasia is the linguistic disability, which usually results from injuries to the dominant hemisphere of the brain. The rehabilitation of aphasia is until in the process of being debated and researched. Evidence-based medicine (EBM), EBM based on the clinical evidence, promotes the practice of combining the clinicians' first-hand experience and the existing objective and scientific evidence encouraging making decisions based on both empirical evidence and the scientific evidence. Currently, EBM is being gradually implemented in the clinical practice as the aim of the development of modern medicine. At present, the research for the aphasia rehabilitation mainly focuses on the cognitive language rehabilitation and the intensive treatment and the precise treatment, etc. There is now sufficient information to support evidence-based protocols and implement empirically-supported treatments for linguistic disability after traumatic brain injury and stroke, which can be used to develop linguistic rehabilitation guidelines for patients with aphasia.

    Objective: The aim is to update our clinical recommendations for evidence-based language rehabilitation of people with aphasia, based on a systematic review of the literature from 1999 to 2015. Data Sources: Articles referred to in this systematic review of the Medline and PubMed published in English language literatures were from 1998 to 2015. The terms used in the literature searches were aphasia and evidenced-based. Study Selection: The task force initially identified citations for 51 published articles. Of the 51 articles, 44 studies were selected after further detailed review. Six articles, which were not written in English, and one study related to laryngectomy rehabilitation interventions, were excluded from the study. This study referred to all the important and English literature in full. Results: Aphasia is the linguistic disability, which usually results from injuries to the dominant hemisphere of the brain. The rehabilitation of aphasia is until in the process of being debated and researched. Evidence-based medicine (EBM), EBM based on the clinical evidence, promotes the practice of combining the clinicians’ first-hand experience and the existing objective and scientific evidence encouraging making decisions based on both empirical evidence and the scientific evidence. Currently, EBM is being gradually implemented in the clinical practice as the aim of the development of modern medicine. Conclusions: At present, the research for the aphasia rehabilitation mainly focuses on the cognitive language rehabilitation and the intensive treatment and the precise treatment, etc. There is now sufficient information to support evidence-based protocols and implement empirically-supported treatments for linguistic disability after traumatic brain injury and stroke, which can be used to develop linguistic rehabilitation guidelines for patients with aphasia.

    The present case study investigated modality-specific aspects of novel word acquisition in aphasia. It was prompted by recent aphasia case studies indicating great interindividual variability in the ability to learn and maintain novel words in aphasia. Moreover, two previous case studies revealed a striking effect of input modality by showing effective word learning and re-learning via visual input only (Kohen, Sola, Tuomiranta, Laine, & Martin, 2012; Tuomiranta et al., 2014). The present participant TS with chronic nonfluent aphasia and post-semantic anomia was administered novel word-referent learning tasks. In the first experiment, the learning phase included simultaneous phonological and orthographic input, while the follow-up was probed separately for spoken and written responses. In the second experiment, we studied the effect of four different input and output modality combinations on her ability to learn to name the novel items. In the first experiment, TS's spoken naming performance during the learning phase was just within the range of healthy controls. Maintenance declined and remained outside that range during the whole 6-month follow-up. However, TS maintained the learned words better in written than in spoken naming throughout the follow-up, and in written naming, her maintenance stayed within the control's range up to 8 weeks post-training. The second experiment indicated that the best learning outcome was achieved with orthographic input. Orthographic input combined with orthographic output resulted in fast and accurate learning of the novel words. Interestingly, TS's test profile was opposite to her learning profile, as she repeated better than she read aloud in the linguistic background assessment. The results from the present case highlight the importance of multiple learning channels for word acquisition in individuals with aphasia. Probing the functionality of different input and output channels for learning may also prove valuable in tailoring

    Apraxia is regularly associated with aphasia, but there is controversy whether their co-occurrence is the expression of a common basic deficit or results from anatomical proximity of their neural substrates. However, neither aphasia nor apraxia is an indivisible entity. Both diagnoses embrace diverse manifestations that may occur more or less independently from each other. Thus, the question whether apraxia is always accompanied by aphasia may lead to conflicting answers depending on which of their manifestations are considered. We used voxel based lesion symptom mapping (VLSM) for exploring communalities between lesion sites associated with aphasia and with apraxia. Linguistic impairment was assessed by the Aachen Aphasia Test (AAT) subtests naming, comprehension, repetition, written language, and Token Test. Apraxia was examined for imitation of meaningless hand and finger postures and for pantomime of tool use. There were two areas of overlap between aphasia and apraxia. Lesions in the anterior temporal lobe interfered with pantomime of tool use and with all linguistic tests. In the left inferior parietal lobe there was a large area where lesions were associated with defective imitation of hand postures and with poor scores on written language and the Token Test. Within this large area there were also two spots in supramarginal and angular gyrus where lesions were also associated with defective pantomime. We speculate that the coincidence of language impairment and defective pantomime after anterior temporal lesions is due to impaired access to semantic memory. The combination of defective imitation of hand postures with poor scores on Token Test and written language is not easily compatible with a crucial role of parietal regions for the conversion of concepts of intended actions into motor commands. It accords better with a role of left inferior parietal lobe regions for the categorical perception of spatial relationships.

    Few studies have investigated the relationships between aphasia and activities of daily living (ADLs) in stroke patients. This study was aimed firstly to determine which task within the ADLs has poorer functional recovery in stroke patients with aphasia after rehabilitation, second to identify which specific task is related to aphasia. This is a prospective and observational study. Inpatients of our Rehabilitation Unit. The study was carried out in 219 patients with primary diagnosis of stroke with (104) and without aphasia (115). All patients underwent usual rehabilitation. Aachen Aphasia Test and Functional Independence Measure scale were used to assess severity of aphasia and ADLs, respectively. Gain in ADLs was the main outcome measure. At the end of rehabilitation patients with aphasia had lower gain in bathing, dressing upper body, dressing lower body, toileting, stair climbing, and higher gain in social interaction, problem solving, and memory with respect to patients without aphasia. However, when data were adjusted for side of hemiplegia, Fugl-Meyer score and trunk control test, patients with aphasia showed lower gain in dressing upper body (P=0.027), dressing lower body (P=0.009), lower toileting (P=0.027), and higher gain in social interaction (P<0.001). In the multivariate regression analysis, aphasia was an important determinant of gain in bathing (β=0.26), dressing upper body (β=0.24), dressing lower body (β=0.22), lower toileting (β=0.22), and social interaction (β=-0.29). The current study points out that, after usual rehabilitation, the patients with aphasia show a poor gain in personal care activities and higher gain in social interaction. Knowledge of these findings: 1) can guide the rehabilitation team in selecting specific and appropriate therapies aimed to give patient with aphasia the highest possible functional independence in ADLs; 2) is useful to family members and social rehabilitation services for domiciliary management of patients

    2016-04-06

    Despite the potential behavioral and neurological benefits of Mindfulness Meditation (MM), its use in treating stroke related communication disabilities appears to be underexplored. Specifically, aphasia, a language disorder resulting from stroke, may be amenable to the benefits of MM because of the observed attention problems often underlying the language symptoms. The current paper presents a case report of an adult with aphasia who was trained in MM. An adult with aphasia completed a five-day mindfulness training, and was assessed on measures of language, attention, and physiological measures of cortisol and heart rate variability. She completed four assessments: two baseline measures, immediately post training, and one week post training (maintenance). Overall, changes were observed in both psychophysiological measures (heart rate and heart rate variability) and behavioral measures (word productivity, phrase length, word generation, decreased impulsivity, and increased attention). Given the psychophysiological and behavioral changes observed in this individual, further exploration of the influence of MM in the treatment of post-stroke aphasia is warranted.

    Recent advances in neuroimaging contribute to a new insights regarding brain-behavior relationships and expand understanding of the functional neuroanatomy of language. Modern concepts of the functional neuroanatomy of language invoke rich and complex models of language comprehension and expression, such as dual stream networks. Increasingly, aphasia is seen as a disruption of cognitive processes underlying language. Rehabilitation of aphasia incorporates evidence based and person-centered approaches. Novel techniques, such as methods of delivering cortical brain stimulation to modulate cortical excitability, such as repetitive transcranial magnetic stimulation and transcranial direct current stimulation, are just beginning to be explored. In this review, we discuss the historical context of the foundations of neuroscientific approaches to language. We sample the emergent theoretical models of the neural substrates of language and cognitive processes underlying aphasia that contribute to more refined and nuanced concepts of language. Current concepts of aphasia rehabilitation are reviewed, including the promising role of cortical stimulation as an adjunct to behavioral therapy and changes in therapeutic approaches based on principles of neuroplasticity and evidence-based/person-centered practice to optimize functional outcomes.

    Background There are several methods of delivering cortical brain stimulation to modulate cortical excitability and interest in their application as an adjuvant strategy in aphasia rehabilitation after stroke is growing. Epidural cortical stimulation, although more invasive than other methods, permits high frequency stimulation of high spatial specificity to targeted neuronal populations. Aims First, we review evidence supporting the use of epidural cortical stimulation for upper limb recovery after focal cortical injury in both animal models and human stroke survivors. These data provide the empirical and theoretical platform underlying the use of epidural cortical stimulation in aphasia. Second, we summarize evidence for the application of epidural cortical stimulation in aphasia. We describe the procedures and primary outcomes of a safety and feasibility study (Cherney, Erickson & Small, 2010), and provide previously unpublished data regarding secondary behavioral outcomes from that study. Main Contribution In a controlled study comparing epidural cortical stimulation plus language treatment (CS/LT) to language treatment alone (LT), eight stroke survivors with nonfluent aphasia received intensive language therapy for 6 weeks. Four of these participants also underwent surgical implantation of an epidural stimulation device which was activated only during therapy sessions. Behavioral data were collected before treatment, immediately after treatment, and at 6 and 12 weeks following the end of treatment. The effect size for the primary outcome measure, the Western Aphasia Battery Aphasia Quotient, was benchmarked as moderate from baseline to immediately post-treatment, and large from baseline to the 12-week follow-up. Similarly, effect sizes obtained at the 12-week follow-up for the Boston Naming Test, the Communicative Effectiveness Index, and for correct information units on a picture description task were greater than those obtained immediately post treatment

    Data about evolution of aphasia following stroke are rare and controversial especially following fibrinolysis. The aim of this study was to describe the early clinical patterns of isolated aphasia in consecutive stroke patients with or without thrombolysis. Clinical and radiological data of consecutive stroke patients were routinely entered in prospective registry. Patients were considered aphasic when NIHSS (National Institutes of Health Stroke Scale) item 9 >0. 'Isolated aphasia' was defined by aphasic patients without motor limb deficit. We created a 'composite language score' obtained by summing the NIHSS items 1b, 1c and 9, which reflects language-processing ability. Recovery of functions was evaluated as measured by global NIHSS, composite language score and language screening test (LAST) at baseline, H24 and day 7 (D7). 'Mild deficit' was defined as global NIHSS <5. A total of 100 consecutive patients met study criteria for isolated aphasia. Twenty-five underwent thrombolysis and 75 did not. There was no difference between the 2 groups concerning demographic characteristics, involved territories and presence of arterial occlusion, initial median NIHSS, composite language and LAST scores at entrance. Evolution was significantly better in thrombolysed patient for the 3 testings: NIHSS, composite language score and LAST at D7 (respective p = 0.0002; p = 0.01 and p = 0.004). Similar results were found when we focused on the subgroups of patients with initial 'mild' deficits (p = 0.01; p = 0.0003 and p = 0.007). No symptomatic hemorrhagic transformation occurred following thrombolysis. These data strongly suggest that thrombolysis is safe and effective in patients with 'isolated aphasia,' even if the global NIHSS score is <5. © 2016 S. Karger AG, Basel.

    Two cases of aphasia after right hemispheric stroke in right handed patients are described. The first patient had a severe mixed transcortical aphasia, apraxia and neglect after a lesion involving the right lenticular nucleus and periventricular white matter; aphasia was still present after three months. The second patient had a mild, transient fluent aphasia after a small right hemispheric periventricular lesion. Studies with [18F]FDG and positron emission tomography (PET) showed functional depression extending to the structurally unaffected left hemisphere in both patients in the acute stage. After three months, in the patient with persistent aphasia, metabolism was still reduced in the right hemisphere, with some recovery of hypometabolism on the left, while metabolic values had returned to normal in the patient with full language recovery. A close parallelism between glucose metabolism and clinical course in crossed aphasia is shown, as well as the presence of a functional involvement of the structurally unaffected left hemisphere in the acute stage.

    Cerebral glucose metabolism was evaluated in patients with either Wernicke's (N = 7), Broca's (N = 11), or conduction (N = 10) aphasia using /sup 18/F-2-fluoro-2-deoxy-D-glucose with positron emission tomography. The three aphasic syndromes differed in the degree of left-to-right frontal metabolic asymmetry, with Broca's aphasia showing severe asymmetry and Wernicke's aphasia mild-to-moderate metabolic asymmetry, while patients with conduction aphasia were metabolically symmetric. On the other hand, the three syndromes showed the same degree of metabolic decline in the left temporal region. The parietal region appeared to separate conduction aphasia from both Broca's and Wernicke's aphasias. Common aphasic features in the three syndromes appear to be due to common changes in the temporal region, while unique features were associated with frontal and parietal metabolic differences.

    We conducted a randomized, double-blind, placebo-controlled, parallel-group study of both memantine and constraint-induced aphasia therapy (CIAT) on chronic poststroke aphasia followed by an open-label extension phase. Patients were randomized to memantine (20 mg/day) or placebo alone during 16 weeks, followed by combined drug treatment with CIAT (weeks 16-18), drug treatment alone (weeks 18-20), and washout (weeks 20-24), and finally, an open-label extension phase of memantine (weeks 24-48). After baseline evaluations, clinical assessments were done at two end points (weeks 16 and 18), and at weeks 20, 24, and 48. Outcome measures were changes in the Western Aphasia Battery-Aphasia Quotient and the Communicative Activity Log. Twenty-eight patients were included, and 27 completed both treatment phases. The memantine group showed significantly better improvement on Western Aphasia Battery-Aphasia Quotient compared with the placebo group while the drug was taken (week 16, p = 0.002; week 18, p = 0.0001; week 20, p = 0.005) and at the washout assessment (p = 0.041). A significant increase in Communicative Activity Log was found in favor of memantine-CIAT relative to placebo-CIAT (week 18, p = 0.040). CIAT treatment led to significant improvement in both groups (p = 0.001), which was even greater under additional memantine treatment (p = 0.038). Beneficial effects of memantine were maintained in the long-term follow-up evaluation, and patients who switched to memantine from placebo experienced a benefit (p = 0.02). Both memantine and CIAT alone improved aphasia severity, but best outcomes were achieved combining memantine with CIAT. Beneficial effects of memantine and CIAT persisted on long-term follow-up.

    Health professionals, researchers, and policy makers often consider the two terms aphasia and dysphasia to be synonymous. The aim of this article is to argue the merits of the exclusive use of the term aphasia and present a strategy for creating change through institutions such as the WHO-ICD. Our contention is that one term avoids confusion, speech-language pathologists prefer aphasia, scholarly publications indicate a preference for the term aphasia, stroke clinical guidelines indicate a preference for the term aphasia, consumer organizations use the title aphasia in their name and on their websites, and languages other than English use a term similar to aphasia. The use of the term dysphasia in the broader medical community may stem from the two terms being used interchangeably in the ICD10. Aphasia United http://www.shrs.uq.edu.au/aphasiaunited , an international movement for uniting the voice of all stakeholders in aphasia within an international context, will seek to eliminate the use of the term dysphasia.

  20. "Speaking for another": the management of participant frames in aphasia.

    A sociolinguistic analysis of an interaction between a woman with aphasia and a nonaphasic speaking partner was conducted to investigate participant framing in aphasia. Participant frames, or the stances that people take in conversation, help conversational participants structure their talk and collaboratively negotiate meaning (I. Goffman, 1974). This analysis revealed a configuration in which a person with severe aphasia enlisted her speaking partner to speak for her. That is, the interaction was framed such that the nonaphasic speaking partner served as the "spokesperson" for messages that were authored by the person with aphasia. The clinical requirements of adopting a "speaking for another" framework are discussed.

    Constraint-induced aphasia therapy (CIAT) offers potential benefits to individuals with history of aphasia-producing ischemic stroke. The goals of this pilot study were to implement the original German CIAT protocol, refine the treatment program, and confirm its efficacy in patients with chronic aphasia. We translated and modified the original CIAT protocol to include a hierarchy of individual skill levels for semantic, syntactic, and phonological language production, while constraining non-use behaviors. Three male participants with moderate to severe post-stroke aphasia received CIAT 3-4 hours/day for 5 consecutive days. Pre and post-testing included formal language evaluation, linguistic analysis of story retell, and mini-Communication Activity Log (mini-CAL). Substantial improvements in comprehension and verbal skills were noted in 2 patients with an increase in the total number of words (31% and 95%) and in number of utterances for story-retell task (57% and 75%). All participants demonstrated an improvement on at least one linguistic measure. No subjective improvements on mini-CAL were noted by any of the participants. Given that the duration of treatment was only 1 week, these linguistic improvements in post stroke aphasia participants were remarkable. The results indicate that the CIAT protocol used in this study may be a useful tool in language restoration after stroke. These initial findings should be confirmed in a larger, randomized study.

    Introduction. Globalization imposes challenges to the field of behavioural neurology, among which is an increase in the prevalence of bilingual aphasia. Thus, aphasiologists have increasingly focused on bilingual aphasia therapy and, more recently, on the identification of the most efficient procedures for triggering language recovery in bilinguals with aphasia. Therapy in both languages is often not available, and, thus, researchers have focused on the transfer of therapy effects from the treated language to the untreated one. Aim. This paper discusses the literature on bilingual aphasia therapy, with a focus on cross-linguistic therapy effects from the language in which therapy is provided to the untreated language. Methods. Fifteen articles including two systematic reviews, providing details on pre- and posttherapy in the adult bilingual population with poststroke aphasia and anomia are discussed with regard to variables that can influence the presence or absence of cross-linguistic transfer of therapy effects. Results and Discussion. The potential for CLT of therapy effects from the treated to the untreated language depends on the word type, the degree of structural overlap between languages, the type of therapy approach, the pre- and postmorbid language proficiency profiles, and the status of the cognitive control circuit.

    Noninvasive brain stimulation such as repetitive transcranial magnetic stimulation (rTMS) or transcranial direct current stimulation (tDCS) has been used in case series and small randomized controlled trials to improve recovery from poststroke aphasia in combination with speech and language therapy. Results of these studies suggest possible clinical efficacy and an excellent safety profile. Therefore, a larger international multicenter proof-of-concept trial was launched, to directly compare the safety and efficacy of rTMS, tDCS, and sham stimulation as adjuvant therapy to speech and language therapy in subacute poststroke aphasia. In the 4 participating centers, subacute stroke patients with aphasia are randomized between 5 and 30 days after ischemic stroke to either receive rTMS, tDCS, or sham stimulation in combination with a daily 45 minutes speech and language therapy session for 10 days. Efficacy is evaluated at 1 and 30 days after the last of the 10 treatment sessions using 3 outcome measures, validated in all participating languages: Boston naming test, Token test, and verbal fluency test. Additionally, adverse events are recorded to prove safety. In this study, a total of 90 patients will be recruited, and data analysis will be completed in 2016. This is the first multilingual and multinational randomized and controlled trial in poststroke aphasia and if positive, will add an effective new strategy for early stage poststroke aphasia rehabilitation.

    Treatment success in aphasia is influenced by various factors. Clinical decisions, including patient selection and decisions on frequency and content, are often guided by a clinician's implicit opinions. The Multi-axial Aphasia System (MAAS) was developed to structure linguistic, somatic, neuropsychological, psychosocial and socio-economic information on five separate axes, enabling an explicit and interdisciplinary process of clinical decision-making. The objectives of this study were to investigate the potentialities of MAAS in predicting the outcome of cognitive-linguistic treatment. A group of 58 aphasic patients were investigated prospectively. All received cognitive-linguistic treatment during a randomized, controlled study on the efficacy of lexical semantic treatment. An interdisciplinary aphasia team rated the pretreatment MAAS profiles of all patients. The team was blinded for treatment allocation and outcome. A multiple linear regression analysis was performed with the posttreatment verbal communication score as the variable to be predicted and the overall MAAS rating, age and type of treatment as predictor variables. In a second multiple regression analysis, the ratings for each of the five MAAS axes were used as candidate predictors. The team's overall rating contributed significantly to the prediction of verbal communicative ability after linguistic treatment. Of the five MAAS axes, the neuropsychological axis contributed to the prediction. An interdisciplinary approach to aphasia assessment may contribute to realistic goal setting in aphasia rehabilitation. The results of this study stress the importance of neuropsychological assessment of aphasic patients before treatment.

    Sudden onset of aphasia is usually due to stroke. Rapid diagnostic workup is necessary if reperfusion therapy is considered. Ictal aphasia is a rare condition but has to be excluded. Perfusion imaging may differentiate acute ischemia from other causes. In dubious cases, EEG is required but is time-consuming and laborious. We report a case where we considered de novo status epilepticus as a cause of aphasia without any lesion even at follow-up. A 62-year-old right-handed woman presented to the emergency department after nurses found her aphasic. She had undergone operative treatment of varicosis 3 days earlier. Apart from hypertension and obesity, no cardiovascular risk factors and no intake of medication other than paracetamol were reported. Neurological examination revealed global aphasia and right pronation in the upper extremity position test. Computed tomography with angiography and perfusion showed no abnormalities. Electroencephalogram performed after the CT scan showed left-sided slowing with high-voltage rhythmic 2/s delta waves but no clear ictal pattern. Intravenous lorazepam did improve EEG slightly, while aphasia did not change. Lumbar puncture was performed which likely excluded encephalitis. Magnetic resonance imaging showed cortical pathological diffusion imaging (restriction) and cortical hyperperfusion in the left parietal region. Intravenous anticonvulsant therapy under continuous EEG resolved neurological symptoms. The patient was kept on anticonvulsant therapy. Magnetic resonance imaging after 6 months showed no abnormalities along with no clinical abnormalities. Magnetic resonance imaging findings were only subtle, and EEG was without clear ictal pattern, so the diagnosis of aphasic status remains with some uncertainty. However, status epilepticus can mimic stroke symptoms and has to be considered in patients with aphasia even when no previous stroke or structural lesions are detectable and EEG shows no epileptic discharges. Epileptic origin is

    People with aphasia and their family members are at high risk of experiencing post stroke depression. The impact of early interventions on mood and quality of life for people with aphasia is unknown. This study will determine whether an early intervention for both the person with aphasia after stroke and their family members leads to better mood and quality of life outcomes for people with aphasia, and less caregiver burden and better mental health for their family members. This is a multicenter, cluster-randomized controlled trial. Clusters, which are represented by Health Service Districts, will be randomized to the experimental intervention (Aphasia Action Success Knowledge Program) or an attention control (Secondary Stroke Prevention Information Program). People with aphasia and their family members will be blinded to the study design and treatment allocation (that is, will not know there are two arms to the study). Both arms of the study will receive usual care in addition to either the experimental or the attention control intervention. A total of 344 people with aphasia and their family members will be recruited. Considering a cluster size of 20, the required sample size can be achieved from 18 clusters. However, 20 clusters will be recruited to account for the potential of cluster attrition during the study. Primary outcome measures will be mood and quality of life of people with aphasia at 12 months post stroke. Secondary measures will be family member outcomes assessing the impact of caregiving and mental health, and self-reported stroke risk-related behaviors of people with aphasia. This is the first known program tailored for people with aphasia and their family members that aims to prevent depression in people with aphasia by providing intervention early after the stroke.

    It has been suggested that public awareness of aphasia is vital for extending services, research support, social inclusion and targeted raising of awareness. Earlier studies show that knowledge of aphasia varies across a range of variables, but is very low compared with other conditions. To report a series of surveys of public awareness of aphasia from six countries, the largest study conducted this far. Surveys were conducted in Argentina (N = 800), Canada (N = 831), Croatia (N = 400), Greece (N = 800), Norway (N = 251) and Slovenia (N = 400) using the same methodology requesting information on age, sex and occupation, asking whether respondents had heard of aphasia and where they had heard of it. Respondents were tested on their levels of knowledge of aphasia. Results revealed low levels of awareness of aphasia in countries surveyed with marked variability that appeared to interact with occupation, country, age and sex. We surveyed 3483 respondents (mean age = 43.16; SD = 17.68). Between 60% (Croatia) and 16% (Slovenia) said they had heard of aphasia (37.1% overall), but those with actual knowledge ranged from 13.9% (Norway) to 1.0% (Argentina). The combined mean of those with basic knowledge was 9.2%. Those who had heard of aphasia were younger; and females had higher levels of awareness. We also found associations between socio-economic status and awareness. Those working in health, social and educational spheres had the highest levels. Respondents mainly heard about aphasia through the media and work or personal contact with aphasia. Levels of awareness are low everywhere in absolute terms, and relative to the awareness of other conditions, with significant variability between countries, sex and socio-economic status. We examine how surveys can be utilized to plan ways to increase understanding and discuss the comparison of awareness of aphasia with other conditions. © 2015 Royal College of Speech and Language Therapists.

    Aphasia is an acquired language disorder with a diverse set of symptoms that can affect virtually any linguistic modality across both the comprehension and production of spoken language. Partial recovery of language function after injury is common but typically incomplete. Rehabilitation strategies focus on behavioral training to induce plasticity in underlying neural circuits to maximize linguistic recovery. Understanding the different neural circuits underlying diverse language functions is a key to developing more effective treatment strategies. This chapter discusses a systems identification analytic approach to the study of linguistic neural representation. The focus of this framework is a quantitative, model-based characterization of speech and language neural representations that can be used to decode, or predict, speech representations from measured brain activity. Recent results of this approach are discussed in the context of applications to understanding the neural basis of aphasia symptoms and the potential to optimize plasticity during the rehabilitation process. © 2013 Elsevier B.V.

    In terms of practical view, the type of aphasia can be classified by four elementary symptoms: anarthria (apraxia of speech), phonemic paraphasia, word comprehension impairment, word finding difficulty. Each elementary symptom has been established by causative lesion: anarthria for lowed posterior part of the left precentral gyrus, phonemic paraphasia for the left marginal gyrus and underlying white matter, word comprehension impairment for the left middle frontal gyrus or the posterior part of superior and middle temporal gyrus (the area called Wernickle's area), word finding difficulty for the left inferior frontal gyrus or the left angular gyrus or the left posterior part of the inferior temporal gyrus. In addition to ordinary estimation of language some devised examination enables distinction of the symptoms due to frontal lesion and the symptom due to the posterior lesion. This methods taking advantage of the symptoms related apahasia is also useful for making diagnosis and knowing prognosis of progressive aphasia.

These data have been transcribed in the Codes for the Human Analysis of Transcripts (CHAT) format for analysis by the Computerized Language Analysis (CLAN) programs. Here, we review results from 45 studies based on these data that investigate aphasic productions in terms of these eight areas: discourse, grammar, lexicon, gesture, fluency, syndrome classification, social factors, and treatment effects. For each area, we also indicate how use of the CLAN programs has facilitated the analysis. We conclude with an examination of ways in which the size of the database could be increased through on-site recordings and data from teletherapy.

The language in the videos is transcribed in CHAT format and coded for analysis with CLAN programs, which can perform a wide variety of language analyses. The database and the CLAN programs are freely available to aphasia researchers and clinicians for educational, clinical and scholarly uses. This paper describes the database, suggests some ways in which clinicians and clinician-researchers might find these materials useful, and introduces a new language analysis program, EVAL, designed to streamline the transcription and coding processes, while still producing an extensive and useful language profile.

    Stroke is one of the leading causes of disability worldwide and aphasia among survivors is common. Current speech and language therapy (SLT) strategies have only limited effectiveness in improving aphasia. A possible adjunct to SLT for improving SLT outcomes might be non-invasive brain stimulation by transcranial direct current stimulation (tDCS) to modulate cortical excitability and hence to improve aphasia. To assess the effects of tDCS for improving aphasia in people who have had a stroke. We searched the Cochrane Stroke Group Trials Register (November 2014), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, November 2014), MEDLINE (1948 to November 2014), EMBASE (1980 to November 2014), CINAHL (1982 to November 2014), AMED (1985 to November 2014), Science Citation Index (1899 to November 2014) and seven additional databases. We also searched trials registers and reference lists, handsearched conference proceedings and contacted authors and equipment manufacturers. We included only randomised controlled trials (RCTs) and randomised controlled cross-over trials (from which we only analysed the first period as a parallel group design) comparing tDCS versus control in adults with aphasia due to stroke. Two review authors independently assessed trial quality and risk of bias, and extracted data. If necessary, we contacted study authors for additional information. We collected information on dropouts and adverse events from the trials. We included 12 trials involving 136 participants for qualitative assessment. None of the included studies used any formal outcome measure for our primary outcome measure of functional communication - that is, measuring aphasia in a real-life communicative setting. We did a meta-analysis of six trials with 66 participants of correct picture naming as our secondary outcome measure, which demonstrated that tDCS may not enhance SLT outcomes (standardised mean difference (SMD) 0.37, 95% CI -0.18 to 0.92; P

    2007-01-01

    At 45 years of age, Charles Baudelaire suffered a left hemispheric stroke that left him with a right hemiplegia and severe aphasia. In this chapter, we investigate the nature of his symptoms, drawing mostly on his own and his contemporaries' correspondence. Before specifically examining his aphasia, we put the poet's life, work, and health in context, notably his tormented mind, his probable syphilitic infection and the intellectual milieu of 19th century France. The time when Baudelaire was struck with aphasia coincides with early discoveries and debates that centered on the nature and implications of this neurological disorder. Many of the questions raised at that time still await definitive answers. Here, we compare Baudelaire's language disorder with recent research that has shed new light on the poet's disease. Most interestingly, we explore the nature of his dramatic use of the expletive Cré nom!, which was the only word he was able to express. Finally, we discuss the links between disease and creativity and dismiss the frequent notion that Baudelaire, in the end, paid the price of his genius.

    2010-01-01

    Background Theories of comprehension deficits in Broca’s aphasia have largely been based on the pattern of deficit found with movement constructions. However, some studies have found comprehension deficits with binding constructions, which do not involve movement. Aims This study investigates online processing and offline comprehension of binding constructions, such as reflexive (e.g., himself) and pronoun (e.g., him) constructions in unimpaired and aphasic individuals in an attempt to evaluate theories of agrammatic comprehension. Methods & Procedures Participants were eight individuals with agrammatic Broca’s aphasia and eight age-matched unimpaired individuals. We used eyetracking to examine online processing of binding constructions while participants listened to stories. Offline comprehension was also tested. Outcomes & Results The eye movement data showed that individuals with Broca’s aphasia were able to automatically process the correct antecedent of reflexives and pronouns. In addition, their syntactic processing of binding was not delayed compared to normal controls. Nevertheless, offline comprehension of both pronouns and reflexives was significantly impaired compared to the control participants. This comprehension failure was reflected in the aphasic participants’ eye movements at sentence end, where fixations to the competitor increased. Conclusions These data suggest that comprehension difficulties with binding constructions seen in agrammatic aphasic patients are not due to a deficit in automatic syntactic processing or delayed processing. Rather, they point to a possible deficit in lexical integration. PMID:20535243

    This study focuses on the controversial issue of the integrity of gestural communication abilities in subjects with aphasia. To define the ability of subjects to interpret symbolic gestures, an Amer-Ind Recognition Test (ART) was developed which required no verbal response from the examiner or the subject. The relationships between impairment of Amer-Ind signal recognition and (a) severity of aphasia, (b) listening and talking abilities and (c) the type of response picture used were investigated. Whether subjects more often chose related foils than unrelated foils in a forced-choice format was also examined. Two training tests and the ART are described. Results from administration to 15 aphasic subjects indicated that: (a) all subjects performed equally well, regardless of their aphasia severity classification; (b) action picture recognition was related to listening ability; (c) action pictures were easier to identify than object pictures; and (d) on error responses, subjects overwhelmingly chose related over unrelated foils. The possibility that gestural abilities were relatively well preserved among the subjects tested, in the presence of a wide range of listening and talking deficits, is also discussed.

    Primary progressive aphasia (PPA) is a neurodegenerative disorder with language impairment as the primary feature. Different subtypes have been described and the 3 best characterized are progressive nonfluent aphasia (PNFA), semantic dementia (SD) and logopenic/phonological aphasia (LPA). Of these subtypes, LPA is most commonly associated with Alzheimer's disease (AD) pathology. However, the features of PPA associated with AD have not been fully defined. Here we retrospectively identified 14 patients with PPA and either pathologically confirmed AD or cerebrospinal fluid (CSF) biomarkers consistent with AD. Analysis of neurological and neuropsychological features revealed that all patients had a syndrome of LPA with relatively nonfluent spontaneous speech, phonemic errors, and reduced digit span; most patients also had impaired verbal episodic memory. Analysis of the pattern of cortical thinning in these patients revealed left posterior superior temporal, inferior parietal, medial temporal, and posterior cingulate involvement and in patients with more severe disease, increasing involvement of left anterior temporal and frontal cortices and right hemisphere areas in the temporo-parietal junction, posterior cingulate, and medial temporal lobe. We propose that LPA may be a “unihemispheric” presentation of AD, and discuss this concept in relation to accumulating evidence concerning language dysfunction in AD. PMID:20580129

    Purpose This study evaluates how proposition density can differentiate between persons with aphasia (PWA) and individuals in a control group, as well as among subtypes of aphasia, on the basis of procedural discourse and personal narratives collected from large samples of participants. Method Participants were 195 PWA and 168 individuals in a control group from the AphasiaBank database. PWA represented 6 aphasia types on the basis of the Western Aphasia Battery–Revised (Kertesz, 2006). Narrative samples were stroke stories for PWA and illness or injury stories for individuals in the control group. Procedural samples were from the peanut-butter-and-jelly-sandwich task. Language samples were transcribed using Codes for the Human Analysis of Transcripts (MacWhinney, 2000) and analyzed using Computerized Language Analysis (MacWhinney, 2000), which automatically computes proposition density (PD) using rules developed for automatic PD measurement by the Computerized Propositional Idea Density Rater program (Brown, Snodgrass, & Covington, 2007; Covington, 2007). Results Participants in the control group scored significantly higher than PWA on both tasks. PD scores were significantly different among the aphasia types for both tasks. Pairwise comparisons for both discourse tasks revealed that PD scores for the Broca's group were significantly lower than those for all groups except Transcortical Motor. No significant quadratic or linear association between PD and severity was found. Conclusion Proposition density is differentially sensitive to aphasia type and most clearly differentiates individuals with Broca's aphasia from the other groups. PMID:27657850

    Positive outcomes from intensive therapy for individuals with aphasia have been reported in the literature. Little is known about the characteristics of individuals who attend intensive comprehensive aphasia programs (ICAPs) and what factors may predict who makes clinically significant changes when attending such programs. Demographic data on participants from 6 ICAPs showed that individuals who attend these programs spanned the entire age range (from adolescence to late adulthood), but they generally tended to be middle-aged and predominantly male. Analysis of outcome data from 2 of these ICAPs found that age and gender were not significant predictors of improved outcome on measures of language ability or functional communication. However, time post onset was related to clinical improvement in functional communication as measured by the Communication Activities of Daily Living, second edition (CADL-2). In addition, for one sample, initial severity of aphasia was related to outcome on the Western Aphasia Battery-Revised, such that individuals with more severe aphasia tended to show greater recovery compared to those with mild aphasia. Initial severity of aphasia also was highly correlated with changes in CADL-2 scores. These results suggest that adults of all ages with aphasia in either the acute or chronic phase of recovery can continue to show positive improvements in language ability and functional communication with intensive treatment.

    There is a growing need for various effective adjunctive treatment options for speech recovery after stroke. A pharmacological agent combined with noninvasive brain stimulation has not been previously reported for poststroke aphasia recovery. In this "proof of concept" study, we aimed to test the safety of a combined intervention consisting of dextroamphetamine, transcranial direct current stimulation, and speech and language therapy in subjects with nonfluent aphasia. Ten subjects with chronic nonfluent aphasia underwent two experiments where they received dextroamphetamine or placebo along with transcranial direct current stimulation and speech and language therapy on two separate days. The Western Aphasia Battery-Revised was used to monitor changes in speech performance. No serious adverse events were observed. There was no significant increase in blood pressure with amphetamine or deterioration in speech and language performance. Western Aphasia Battery-Revised aphasia quotient and language quotient showed a statistically significant increase in the active experiment. Comparison of proportional changes of aphasia quotient and language quotient in active experiment with those in placebo experiment showed significant difference. We showed that the triple combination therapy is safe and implementable and seems to induce positive changes in speech and language performance in the patients with chronic nonfluent aphasia due to stroke.

    2014-04-01

    This study reports on current aphasia rehabilitation practices of speech-language pathologists in Australia. A 30-item web-based survey targeted approaches to aphasia rehabilitation, education, discharge, follow-up practices, counselling, interventions to improve communication access, community aphasia support services, and challenges to practice. One hundred and eighty-eight surveys were completed representing ~33% of the potential target population, with 58.5% urban and 41.5% rural participants across all states and territories. Respondents reported embracing a wide variety of approaches to aphasia rehabilitation; however, significant challenges in providing aphasia management in acute and residential care were identified. Low levels of knowledge and confidence were reported for both culturally and linguistically diverse clients and discourse approaches. Group and intensive services were under-utilized and clinicians reported inflexible funding models as major barriers to implementation. Few clinicians work directly in the community to improve communicative access for people with aphasia. Despite the chronic nature of aphasia, follow-up practices are limited and client re-entry to services is restricted. Counselling is a high frequency practice in aphasia rehabilitation, but clinicians report being under-prepared for the role. Respondents repeatedly cited lack of resources (time, space, materials) as a major challenge to effective service provision. Collective advocacy is required to achieve system level changes.

    2016-06-01

    [Purpose] This study explored health science students' perceptions of motor aphasia and sensory aphasia caused by stroke to provide basic material for the improvement of rehabilitation practitioners' perceptions of aphasia. [Subjects and Methods] The subjects of this study were 642 freshmen and sophomores majoring in health science. Perceptions of aphasia were surveyed on a semantic differential scale using the Anchoring Vignette Method and the difference in perception of the two types of aphasia was analyzed using multi-dimensional scaling. [Results] The analysis revealed that motor aphasia and sensory aphasia have mutually corresponding images. Motor aphasia had high levels of 'quiet', 'passive' 'dumb', 'unstable' and 'gloomy' images, while sensory aphasia had high levels of 'noisy', 'unstable', 'cheerful', 'sensitive', 'fluctuating in emotions', 'active', 'dumb' and 'gloomy' images. [Conclusion] A systematic education is required to be implemented in the future to improve health science students' negative perceptions of the aftereffects of stroke such as aphasia.

  8. Impairment and Functional Interventions for Aphasia: Having it All

    PubMed Central

    Barrett, A. M.

    2014-01-01

    Aphasia, a cognitive-linguistic disorder secondary to stroke, is a frequent and often chronic consequence of stroke with detrimental effects on autonomy and health-related quality of life. Treatment of aphasia can be approached in a number of ways. Impairment-based approaches that focus on training a specific linguistic form can be implemented. Additionally, functionally oriented intervention such as supported conversation and aphasia groups are also frequently utilized when providing a treatment program for an individual with aphasia. Creating a treatment approach that includes both impairment and functional methodologies and considers how these relate to the three domains proposed by the International Classification of Functioning Disability and Health (ICF)—body functions and structure, activity, and participation—can provide an individual with aphasia an optimal treatment program that is person-centered and multi-faceted.

  9. Neuroscience of aphasia recovery: the concept of neural multifunctionality.

    PubMed

    Cahana-Amitay, Dalia; Albert, Martin L

    2015-07-01

    Aphasia therapy, while demonstrably successful, has been limited by its primary focus on language, with relatively less attention paid to nonlinguistic factors (cognitive, affective, praxic) that play a major role in recovery from aphasia. Neuroscientific studies of the past 15-20 years have opened a breach in the wall of traditional clinico-anatomical teachings on aphasia. It is not an exaggeration to talk of a paradigm shift. The term "neural multifunctionality" denotes a complex web of neural networks supporting both linguistic and nonlinguistic functions in constant and dynamic interaction, creating language as we know it and contributing to recovery from aphasia following brain damage. This paper reviews scientific underpinnings of neural multifunctionality and suggests ways in which this new approach to understanding the neural basis of language can lead to meaningful, practical steps for improvements in aphasia therapy.

    1986-11-01

    An autopsied case of jargon aphasia by multiple cerebral infarction was reported. A 75-year-old right-handed woman developed a Wernicke's aphasia with the first attack of cerebral infarction in the left hemisphere in July 1980. With the second attack of infarction in October 1980, she developed a neologistic and semantic jargon aphasia, in which her speech consisted of neologisms, literal paraphasias, empty phrases and so-called "misused words". CT-findings showed two low density areas; one was in the left hemisphere and the other in the posterior region of the right hemisphere. Her jargon aphasia persisted for about one year. In November 1981, she suffered a third attack of infarction and developed an apallic syndrome. Neuropathological examination confirmed that the lesion of the right hemisphere played a decisive role in the outbreak of jargon aphasia in this case.

    Chronic aphasia is a common consequence of a left-hemisphere stroke. Since the early insights by Broca and Wernicke, studying the relationship between the loci of cortical damage and patterns of language impairment has been one of the concerns of aphasiology. We utilized multivariate classification in a cross-validation framework to predict the type of chronic aphasia from the spatial pattern of brain damage. Our sample consisted of 98 patients with five types of aphasia (Broca’s, Wernicke’s, global, conduction, and anomic), classified based on scores on the Western Aphasia Battery. Binary lesion maps were obtained from structural MRI scans (obtained at least 6 months poststroke, and within 2 days of behavioural assessment); after spatial normalization, the lesions were parcellated into a disjoint set of brain areas. The proportion of damage to the brain areas was used to classify patients’ aphasia type. To create this parcellation, we relied on five brain atlases; our classifier (support vector machine) could differentiate between different kinds of aphasia using any of the five parcellations. In our sample, the best classification accuracy was obtained when using a novel parcellation that combined two previously published brain atlases, with the first atlas providing the segmentation of grey matter, and the second atlas used to segment the white matter. For each aphasia type, we computed the relative importance of different brain areas for distinguishing it from other aphasia types; our findings were consistent with previously published reports of lesion locations implicated in different types of aphasia. Overall, our results revealed that automated multivariate classification could distinguish between aphasia types based on damage to atlas-defined brain areas. PMID:26465238

    We report the adaptation of the Aachen Aphasia Test (AAT) to the Portuguese language (PAAT) and the results of its standardization in 125 persons with aphasia and 153 healthy controls. Patients with aphasia had a previous syndromic diagnosis, obtained through a Portuguese aphasia battery, which served as a reference. The control group was stratified by age and educational level. Hierarchical cluster analyses showed good construct validity. The increasing degree of difficulty and complexity throughout the item sets comprising subtests was confirmed. The discriminatory power of the PAAT for the selection of aphasic from non-aphasic persons proved to be as high as for the AAT versions in other languages. Classification of standard aphasic syndromes by means of discriminant analyses was good. Internal consistency, measured by means of Cronbach's alpha coefficient, was high to very high for the different PAAT subtests. Performance differences caused by age or educational level among the healthy control persons emphasized the need for correction factors. In conclusion, the PAAT showed robust psychometric properties, comparable to the original German and to adaptations to other languages. It constitutes a useful tool for cross-linguistic and multicenter studies.

    The authors compared the effectiveness of 2 intensive therapy methods: Constraint-Induced Aphasia Therapy (CIAT; Pulvermüller et al., 2001) and semantic therapy (BOX; Visch-Brink & Bajema, 2001). Nine patients with chronic fluent aphasia participated in a therapy program to establish behavioral treatment outcomes. Participants were randomly assigned to one of two groups (CIAT or BOX). Intensive therapy significantly improved verbal communication. However, BOX treatment showed a more pronounced improvement on two communication-namely, a standardized assessment for verbal communication, the Amsterdam Nijmegen Everyday Language Test (Blomert, Koster, & Kean, 1995), and a subjective rating scale, the Communicative Effectiveness Index (Lomas et al., 1989). All participants significantly improved on one (or more) subtests of the Aachen Aphasia Test (Graetz, de Bleser, & Willmes, 1992), an impairment-focused assessment. There was a treatment-specific effect. BOX treatment had a significant effect on language comprehension and semantics, whereas CIAT treatment affected language production and phonology. The findings indicate that in patients with fluent aphasia, (a) intensive treatment has a significant effect on language and verbal communication, (b) intensive therapy results in selective treatment effects, and (c) an intensive semantic treatment shows a more striking mean improvement on verbal communication in comparison with communication-based CIAT treatment.

    Background: Language disturbance is a common symptom of stroke, a prompt identifier of the event, and can cause devastating cognitive impairments. There are many inconsistencies and discrepancies between the different methods used for its evaluation. The relationship between Western Aphasia Battery (WAB) and a simple bedside clinical examination is not clear. Aim: The aim of this study is to determine if bedside clinical impression of aphasia type can reliably predict WAB classification of aphasia and to describe the discrepancies between them. Materials and Methods: Eighty-two consecutive cases of acute ischemic stroke and aphasia were evaluated with bedside aphasia assessment, handedness by Edinburgh Handedness Inventory and WAB scoring was done. Kappa statistics was used to find the overall agreement of clinical impression and WAB. Results: Disagreement was seen predominantly for the nonfluent aphasias when the clinical impression was compared with WAB classification. WAB also had diagnosed three cases as having anomic aphasia using taxonomic classification, but same cases had normal language by aphasia quotient scoring of WAB. There was an overall agreement of 63.4% between patient's bedside clinical impression and WAB classification of aphasia, with a P < 0.001. Conclusion: Clinical impression was fairly reliable, as compared to WAB in assessing the type of aphasia. Clinical impression was appropriate in an acute setting, but WAB was required to quantify the severity of deficit, which may help in accessing prognosis, monitoring progression, and rehabilitation planning. Along with WAB, a bedside clinical impression should be done for all the patients to strengthen the description of aphasic deficit. PMID:28149086

    As an example of complex auditory signal processing, the analysis of accented speech is potentially vulnerable in the progressive aphasias. However, the brain basis of accent processing and the effects of neurodegenerative disease on this processing are not well understood. Here we undertook a detailed neuropsychological study of a patient, AA with progressive nonfluent aphasia, in whom agnosia for accents was a prominent clinical feature. We designed a battery to assess AA's ability to process accents in relation to other complex auditory signals. AA's performance was compared with a cohort of 12 healthy age and gender matched control participants and with a second patient, PA, who had semantic dementia with phonagnosia and prosopagnosia but no reported difficulties with accent processing. Relative to healthy controls, the patients showed distinct profiles of accent agnosia. AA showed markedly impaired ability to distinguish change in an individual's accent despite being able to discriminate phonemes and voices (apperceptive accent agnosia); and in addition, a severe deficit of accent identification. In contrast, PA was able to perceive changes in accents, phonemes and voices normally, but showed a relatively mild deficit of accent identification (associative accent agnosia). Both patients showed deficits of voice and environmental sound identification, however PA showed an additional deficit of face identification whereas AA was able to identify (though not name) faces normally. These profiles suggest that AA has conjoint (or interacting) deficits involving both apperceptive and semantic processing of accents, while PA has a primary semantic (associative) deficit affecting accents along with other kinds of auditory objects and extending beyond the auditory modality. Brain MRI revealed left peri-Sylvian atrophy in case AA and relatively focal asymmetric (predominantly right sided) temporal lobe atrophy in case PA. These cases provide further evidence for the

    Wernicke's aphasia occurs after a stroke to classical language comprehension regions in the left temporoparietal cortex. Consequently, auditory-verbal comprehension is significantly impaired in Wernicke's aphasia but the capacity to comprehend visually presented materials (written words and pictures) is partially spared. This study used functional magnetic resonance imaging to investigate the neural basis of written word and picture semantic processing in Wernicke's aphasia, with the wider aim of examining how the semantic system is altered after damage to the classical comprehension regions. Twelve participants with chronic Wernicke's aphasia and 12 control participants performed semantic animate-inanimate judgements and a visual height judgement baseline task. Whole brain and region of interest analysis in Wernicke's aphasia and control participants found that semantic judgements were underpinned by activation in the ventral and anterior temporal lobes bilaterally. The Wernicke's aphasia group displayed an 'over-activation' in comparison with control participants, indicating that anterior temporal lobe regions become increasingly influential following reduction in posterior semantic resources. Semantic processing of written words in Wernicke's aphasia was additionally supported by recruitment of the right anterior superior temporal lobe, a region previously associated with recovery from auditory-verbal comprehension impairments. Overall, the results provide support for models in which the anterior temporal lobes are crucial for multimodal semantic processing and that these regions may be accessed without support from classic posterior comprehension regions.

    Considerable attention has been given to the identification of depression in stroke survivors with aphasia, but there is more limited information about other mood states. Visual analog scales are often used to collect subjective information from people with aphasia. However, the validity of these methods for communicating about mood has not been established in people with moderately to severely impaired language. The dual purposes of this study were to characterize the relative endorsement of negative and positive mood states in people with chronic aphasia after stroke and to examine congruent validity for visual analog rating methods for people with a range of aphasia severity. Twenty-three left-hemisphere stroke survivors with aphasia were asked to indicate their present mood by using two published visual analog rating methods. The congruence between the methods was estimated through correlation analysis, and scores for different moods were compared. Endorsement was significantly stronger for "happy" than for mood states with negative valence. At the same time, several participants displayed pronounced negative mood compared to previously published norms for neurologically healthy adults. Results from the two rating methods were moderately and positively correlated. Positive mood is prominent in people with aphasia who are in the chronic stage of recovery after stroke, but negative moods can also be salient and individual presentations are diverse. Visual analog rating methods are valid methods for discussing mood with people with aphasia; however, design optimization should be explored.

  1. Verb Argument Structure in Narrative Speech: Mining AphasiaBank.

    Previous research has found that verb argument structure characteristics (such as the number of participant roles in the situation described by the verb) can facilitate or hinder aphasic language production and comprehension in constrained laboratory tasks. This research needs to be complemented by studies of narrative or unrestricted speech, which can capture the spontaneous selection of verbs and grammatical structures by people with aphasia and may be particularly sensitive to the relative cost of access to different verb types in more natural conditions. Focusing on the number of subcategorization options, we investigated verb argument structure effects in a large sample of narratives from AphasiaBank, by speakers with aphasia, as well as control speakers without brain damage. Verb argument structure complexity did not negatively affect verb selection in any type of aphasia. However, people with aphasia, particularly with Broca's aphasia, used verbs in less complex and diverse ways, with fewer arguments and less diverse subcategorization options. In line with previous research, this suggests that deficits in verb use in aphasia are likely due to difficulties with the online application of or partial damage to verb argument structure knowledge.

    To study the independence of gesture and verbal language production. The authors assessed whether gesture can be semantically compensatory in cases of verbal language impairment and whether speakers with aphasia and control participants use similar depiction techniques in gesture. The informativeness of gesture was assessed in 3 forced-choice studies, in which raters assessed the topic of the speaker's message in video clips of 13 speakers with moderate aphasia and 12 speakers with severe aphasia, who were performing a communication test (the Scenario Test). Both groups were compared and contrasted with 17 control participants, who either were or were not allowed to communicate verbally. In addition, the representation techniques used in gesture were analyzed. Gestures produced by speakers with more severe aphasia were less informative than those by speakers with moderate aphasia, yet they were not necessarily uninformative. Speakers with more severe aphasia also tended to use fewer representation techniques (mostly relying on outlining gestures) in co-speech gesture than control participants, who were asked to use gesture instead of speech. It is important to note that limb apraxia may be a mediating factor here. These results suggest that in aphasia, gesture tends to degrade with verbal language. This may imply that the processes underlying verbal language and co-speech gesture production, although partly separate, are closely linked.

    The use of functional neuroimaging techniques has advanced what is known about the neural mechanisms used to support language processing in aphasia resulting from brain damage. This paper highlights recent findings derived from neuroimaging studies focused on neuroplasticity of language networks, the role of the left and right hemispheres in this process, and studies examining how treatment affects the neurobiology of recovery. We point out variability across studies as well as factors related to this variability, and we emphasize challenges that remain for research. PMID:18957184

    Six severely aphasic patients were trained on C-VIC, a computerized alternative communication system. Patients with both global and Broca's aphasia were able to produce and comprehend locative prepositions using C-VIC. The Broca's aphasic patients were able to produce and interpret symbol order correctly in C-VIC locative prepositional phrases, despite their difficulties in performing the same tasks using English. One patient's verbal production of locative prepositional phrases improved markedly after C-VIC training. These results suggest that the "mapping" impairment suffered by some Broca's aphasics may be ameliorated by use of alternative communication system, such as C-VIC.

Isolated writing disturbances persisted for seven months until he had a second cerebrovascular accident resulting in total aphasia and right hemiplegia. A CAT scan obtained four months after the first episode showed a localised dilatation of the posterior portion of the left Sylvian cistern and patchy areas of low absorption in the left temporal lobe. The report supports suggestions that localised damage to the language area can produce a pure agraphia as the sole detectable disorder of language organisation. Images PMID:438836

    The sequelae of post-stroke aphasia are considerable, necessitating an understanding of the functional neuroanatomy of language, cognitive processes underlying various language tasks, and the mechanisms of recovery after stroke. This knowledge is vital in providing optimal care of individuals with aphasia and counseling to their families and caregivers. The standard of care in the rehabilitation of aphasia dictates that treatment be evidence-based and person-centered. Promising techniques, such as cortical stimulation as an adjunct to behavioral therapy, are just beginning to be explored. These topics are discussed in this review. PMID:28713549

    Purpose Treatment studies have documented the therapeutic and functional value of lexical writing treatment for individuals with severe aphasia. The purpose of this study was to determine whether such retraining could be accomplished using the typing feature of a cellular telephone, with the ultimate goal of using text messaging for communication. Method A 31-year-old man with persistent Broca’s aphasia, severe apraxia of speech, global dysgraphia, and right hemiparesis participated in this study. Using a multiple baseline design, relearning and maintenance of single-word spellings (and oral naming) of targeted items were examined in response to traditional Copy and Recall Treatment (CART) for handwriting and a new paradigm using 1-handed typing on a cell phone keyboard (i.e., a texting version of CART referred to as T-CART). Results Marked improvements were documented in spelling and spoken naming trained in either modality, with stronger maintenance for handwriting than cell phone typing. Training resulted in functional use of texting that continued for 2 years after treatment. Conclusions These results suggest that orthographic retraining using a cell phone keyboard has the potential to improve spelling knowledge and provide a means to improve functional communication skills. Combined training with both handwriting and cell phone typing should be considered in order to maximize the durability of treatment effects. PMID:23811474

    A referred cohort of 67 clinically defined PPA patients were compared to 99 AD patients with formal language and nonverbal cognitive tests in a case control design. Language fluency was determined at the first and last follow up visits. Quantitation of sulcal and ventricular atrophy on MRI was carried out in 46 PPA and 53 AD patients. Most PPA patients (57%) are relatively fluent when first examined. Visuospatial and memory functions are initially preserved. Aphemic, stuttering, "pure motor" presentation, or agrammatic aphasia are seen less frequently. Later most PPAs become logopenic and nonfluent, even those with semantic aphasia (dementia). In contrast, AD patients were more fluent and had relatively lower comprehension, but better overall language performance. MRI showed significant left sided atrophy in most PPA patients. Subsequent to PPA, 25 patients developed behavioral manifestations of frontotemporal dementia and 15 the corticobasal degeneration syndrome, indicating the substantial clinical overlap of these conditions. Language testing, particularly fluency scores supported by neuroimaging are helpful differentiating PPA from AD. The fluent-nonfluent dichotomy in PPA is mostly stage related. The aphemic-logopenic-agrammatic and semantic distinction is useful, but the outcomes converge.

    This paper investigates recurrent use of the phrase very good by a speaker with non-fluent agrammatic aphasia. Informal observation of the speaker's interaction reveals that she appears to be an effective conversational partner despite very severe word retrieval difficulties that result in extensive reliance on variants of the phrase very good. The question that this paper addresses using an essentially conversation analytic framework is: What is the speaker achieving through these variants of very good and what are the linguistic and interactional resources that she draws on to achieve these communicative effects? Tokens of very good in the corpus were first analyzed in a bottom-up fashion, attending to sequential position, structure and participant orientation. This revealed distinct uses that were subsequently subjected to detailed acoustic analysis in order to investigate specific prosodic characteristics within and across the interactional variants. We identified specific clusters of prosodic cues that were exploited by the speaker to differentiate interactional uses of very good. The analysis thus shows how, in the adaptation to aphasia, the speaker exploits the rich interface between prosody, grammar and interaction both to manage the interactional demands of conversation and to communicate propositional content.

    Speech and language therapy is essential in the rehabilitation of aphasic disorders following a stroke. Due to the predicted increase of aphasia and limited resources within the healthcare system, the development of efficient and sustainable treatment methods is of exceptional importance. The effectiveness of both traditional and innovative approaches needs to be evaluated against the standards of evidence-based medicine. Class I evidence has been established for high-intensity speech and language therapy in subacute and chronic stages of aphasia. Innovative training-based approaches have so far only been evaluated in small studies but promising results have been shown for computer-based naming, video-based exercises for verbalization of complex contents and approaches modeled according to "forced-use" principles with standardized contents. Adjuvant training therapies are being developed to increase and prolong the impact of training alone, most notably non-invasive brain stimulation and pharmacological modulation. Transcranial direct current stimulation has been shown to effectively enhance training in several small randomized controlled trials but several questions still remain to be answered, including the location of electrode placement as well as the length and intensity of stimulation. Mixed evidence has been collected for the effectiveness of pharmacotherapy on speech learning and further randomized controlled trials are also needed to allow more firmly based recommendations.

    Language processing requires the coordinated interaction of local and distant neural populations within distributed networks of the temporal, frontal and parietal brain regions. Poststroke aphasia is the consequence of both local as well as remote dysfunction within language-specific and domain-general networks. Language recovery, in turn, rests on reorganization processes within these networks. These comprise the resolution of an acute network failure (i. e. diaschisis), the subacute activation of right hemisphere homologous regions and the gradual reintegration of left hemisphere remote and perilesional areas. The application of unifocal noninvasive brain stimulation over these regions provides a means of modulating neural plasticity in order to enhance the reorganization processes underlying language recovery. The lack of knowledge as to the optimal stimulation site, the appropriate stimulation protocol and the proper timing of interventions might explain the only marginal effects of brain stimulation adjunct to speech and language therapy. In addition, individually different contributions of left and right hemisphere regions to recovery due to heterogeneous lesion sites among patients limit the possibility to identify general principles for brain stimulation. The assumption that aphasia is not only the consequence of the focal effect of a brain lesion but arises from remote dysfunctions within associated functional networks ignites the concept for individualized, potentially multifocal therapeutic network modulation.

    Abstract Background Few studies have investigated how people with aphasia (PWA) experience literacy skills. Taking the insider's perspective is a way to increase understanding of the individual experiences of literacy among PWA, which may have clinical implications. Aims To describe how literacy, i.e., reading and writing, is experienced in everyday life by PWA and to gain insight into the part played by literacy skills in their lives. Methods & Procedures A qualitative descriptive research approach was taken. In‐depth interviews were conducted with 12 PWA (six women and six men) who had all lived with aphasia for at least 6 months post‐stroke. The interviews were analysed using qualitative content analysis. Outcomes & Results One overarching theme emerged from the data: literacy as an ongoing recovery process. Based on this overarching theme, two subthemes were identified: changes in conditions for literacy (experiences of reading and writing initially post‐onset compared with experiences at the time of the interview); and facing expectations about literacy (participants’ own and other people's expectations of them in terms of literacy). Conclusions & Implications The findings are important at a general level in that they indicate that PWA are able to articulate their individual experiences and thoughts about literacy, i.e., reading and writing. Specifically, PWA in this study experience literacy as playing an essential part in their lives and the findings imply that personal experiences are important in the design of reading and writing interventions in speech and language therapy.

    We sought to investigate the decision making profile of Primary Progressive Aphasia (PPA) by assessing patients diagnosed with this disease (n = 10), patients diagnosed with behavioral variant frontotemporal dementia (bvFTD, n = 35), and matched controls (n = 14) using the Iowa Gambling Task, a widely used test that mimics real-life decision making. Participants were also evaluated with a complete neuropsychological battery. Patients with PPA were unable to adopt an advantageous strategy on the IGT, which resulted in a flat performance, different to that exhibited by both controls (who showed advantageous decision making) and bvFTD patients (who showed risk-appetitive behavior). The decision making profile of PPA patients was not associated with performance on language tasks and did not differ between sub-variants of the disease (namely, semantic dementia and progressive nonfluent aphasia). Investigating decision making in PPA is crucial both from a theoretical perspective, as it can shed light about the way in which language interacts with other cognitive functions, as well as a clinical standpoint, as it could lead to a more objective detection of impairments of decision making deficits in this condition.

    The neurolinguistic and cognitive profiles of a patient with mixed transcortical aphasia and non-familial dysphasic dementia associated with progressive, left perisylvian involution are presented. This clinicopathological entity has recently been shown to be an example of a novel class of intrinsic, focal cortical degenerations with sparing of the basal forebrain. The characteristics of the aphasia were unusual. There were occasional literal and verbal paraphasic errors, but no completion phenomenon, embellishment or significant echolalia. Evidence of a generalized lexical disruption was found on detailed analysis of residual abilities in reading, writing and spelling. A newly described form of non-lexical repetition was present, resulting in the patient's inability to correct syntactical and semantic errors. Affective prosodic repetition was intact. A combined paraphasic word-production and semantic anomia was found. These observations combined with evidence of evolving region-specific cognitive impairments suggest that the pathological process resulted in a relative disconnection of integral frontal and parieto-occipital areas from adjacent perisylvian language zones.

    A left parietal infarct in a prelingually deaf person resulted in an aphasia for both American Sign Language (ASL) and written and finger-spelled English. Originally the patient had a nearly global aphasia affecting all language systems. By five to seven weeks post-onset her symptoms resembled those of hearing aphasics with posterior lesions: fluent but paraphasic signing, anomia, impaired comprehension and repetition, alexia, and agraphia with elements of neologistic jargon. In addition, there was a pronounced sequential movement copying disorder, reduced short-term verbal memory and acalculia. In general, the patient's sign errors showed a consistent disruption in the structure of ASL signs which parallels the speech errors of oral aphasic patients. We conclude that most aphasic symptoms are not modality-dependent, but rather reflect a disruption of linguistic processes common to all human languages. This case confirms the importance of the left hemisphere in the processing of sign language. Furthermore, the results indicate that the left supramarginal and angular gyri are necessary substrates for the comprehension of visual/gestural languages.

    Current research on bilingual aphasia highlights the paucity in recommendations for optimal rehabilitation for bilingual aphasic patients (Roberts & Kiran, 2007; Edmonds & Kiran, 2006). In this paper, we have developed a computational model to simulate an English-Spanish bilingual language system in which language representations can vary by age of acquisition (AoA) and relative proficiency in the two languages to model individual participants. This model is subsequently lesioned by varying connection strengths between the semantic and phonological networks and retrained based on individual patient demographic information to evaluate whether or not the model’s prediction of rehabilitation matched the actual treatment outcome. In most cases the model comes close to the target performance subsequent to language therapy in the language trained, indicating the validity of this model in simulating rehabilitation of naming impairment in bilingual aphasia. Additionally, the amount of cross-language transfer is limited both in the patient performance and in the model’s predictions and is dependent on that specific patient’s AoA, language exposure and language impairment. It also suggests how well alternative treatment scenarios would have fared, including some cases where the alternative would have done better. Overall, the study suggests how computational modeling could be used in the future to design customized treatment recipes that result in better recovery than is currently possible. PMID:24600315

    1978-09-01

    This paper discusses certain aspects of the speech patterns of neologistic jargon aphasic patients, whose syndrome is one form of a more general classification referred to as Wernicke's or cortical sensory aphasia. The classical lesion site is in the posterior superior temporal convolution of the dominant hemisphere. Patients with such lesions typically have difficulties in the comprehension of auditory linguistic stimuli and their speech is often marked with neologistic jargon. A neologism is a phonological form produced by the patient for which one cannot recover with any reasonable degree of certainty some single item in the patient's vocabulary as it presumably existed before the onset of the disease. Specific analysis is focused on those stretches of speech which exhibit perseveration to the point where there is an excessive amount of alliteration and assonance. The data is described in terms of segments, syllables and sequences of syllables and related to both a mechanism underlying the production of this sort of speech and to the more general problems of neologisms in jargon aphasia.

    Implicit learning is a process of acquiring knowledge that occurs without conscious awareness of learning, whereas explicit learning involves the use of overt strategies. To date, research related to implicit learning following stroke has been largely restricted to the motor domain and has rarely addressed implications for language. The present study investigated implicit and explicit learning of an auditory word sequence in 10 individuals with stroke-induced agrammatic aphasia and 18 healthy age-matched participants using an adaptation of the Serial Reaction Time task. Individuals with aphasia showed significant learning under implicit, but not explicit, conditions, whereas age-matched participants learned under both conditions. These results suggest significant implicit learning ability in agrammatic aphasia. Furthermore, results of an auditory sentence span task indicated working memory deficits in individuals with agrammatic aphasia, which are discussed in relation to explicit and implicit learning processes.

    The lack of a standardized Thai Language aphasia test raises difficulties not only with the assessment and treatment planning for the clinical but also with the accurate diagnosis and the reliable incidence for research on aphasiology in Thailand. This study aimed to use the Thai version of German Aachen aphasia (THAI-AAT), which is systematically adapted according to well-defined linguistic criteria and psychometric requirement, to assess the language deficit of Thai aphasic patients. The subjects participating in this study were 125 aphasia patients, 60 non-aphasic brain damaged patients and 120 normal subjects. The result revealed that the THAI-AAT is linguistically parallel in test design and fulfills the same psychometric properties as the original. The THAI-AAT obtains the goals: to differential diagnosis of aphasia distinguishing it from non-aphasic disturbance and to identify the type of aphasic syndrome.

Ninety-seven percent of subjects showed metabolic abnormalities in the angular gyrus, 89% in the supramarginal gyrus, and 87% in the lateral and transverse superior temporal gyrus. Pearson product moment correlations were calculated between regional metabolic measures and performance on the Western Aphasia Battery. No significant correlations were found between the Western Aphasia Battery scores and right hemisphere metabolic measures. Most left hemisphere regions correlated with more than one score from the Western Aphasia Battery. Temporal but not frontal regions had significant correlations to the comprehension score. The left temporoparietal region was consistently affected in these subjects, suggesting that common features in the aphasias were caused by left temporoparietal dysfunction, while behavioral differences resulted from (1) the extent of temporoparietal changes, and (2) dysfunction elsewhere in the brain, particularly the left frontal and subcortical areas.

    Spelling - a core language skill - is commonly affected in neurological diseases such as stroke and Primary Progressive Aphasia (PPA). We present two case studies of the same spelling therapy (learning of phoneme-to-grapheme correspondences with help from key words) in two participants: one who had a stroke and one with PPA (logopenic variant). Our study highlights similarities and differences in the time course of each indivdual's therapy. The study evaluates the effectiveness and generalization of treatment in each case, i.e. whether the treatment affected the trained items and/or untrained items, and whether or not the treatment gains were maintained after the end of therapy. Both participants were able to learn associations between phonemes and graphemes as well as between phonemes and words. Reliable generalization to untrained words was shown only for the participant with post-stroke aphasia, but we were not able to test generalization to untrained words in the individual with PPA. The same spelling therapy followed a different time course in each case. The participant with post-stroke aphasia showed a lasting effect of improved spelling, but we were unable to assess maintenance of improvement in the participant with PPA. We discuss these differences in light of the underlying nature of each disease.

    Early identification of patients with stroke-induced aphasia is essential because it is a significant disability affecting daily life and is linked to poor functional outcome after stroke. However, most patients with stroke are unable to undergo aphasia evaluation and detection and therefore remain undiagnosed. The purpose of this study is to develop a valid, reliable mobile aphasia screening test (MAST) for patients in remote locations. To accomplish this, we enrolled patients with (n=30) and without (n=30) stroke-induced aphasia. A MAST, which adopted the Korean version of the shortened version of the Frenchay Aphasia Screening Test (K-FAST), was designed as an iPad(®) (Apple, Cupertino, CA) application. To validate the MAST, we compared its performance with that of the Korean version of the Western Aphasia Battery (K-WAB) and conventional shortened FAST paper version (K-FAST). We analyzed interrater and internal reliability, using Cronbach's alpha coefficient, and assessed the diagnostic sensitivity, specificity, and power. There was significant correlation between K-FAST and MAST (intraclass correlation coefficient [ICC]=0.995, p<0.001). MAST also had a high correlation with K-WAB (ICC=0.752, p<0.001). Interrater reliability was very high (ICC=0.999, p<0.001). The test had high sensitivity (90.0%) and specificity (73.3%) with an accuracy of 0.930 (95% confidence interval=0.853-1.000). The MAST is a valid and reliable tool for detecting aphasia in patients with stroke. This telescreening test may overcome the limitations of test administration and may be a convenient and cost-effective alternative to the existing aphasia screening tests for patients with stroke.

    PubMed

    Hazif-Thomas, Cyril; Thomas, Philippe

    Alzheimer's disease is accompanied by gradual aphasia, becoming more severe when the cognitive disorders are more marked. However, the quality of care provided to the patient can modulate the evolution of these language difficulties. Aphasia is linked to a human communication deficiency and can be limited by taking into account the phatic function of language to keep the channels of communication open. Copyright © 2017.

  10. Measuring the lexical semantics of picture description in aphasia

    PubMed Central

    Gordon, Jean K.

    2012-01-01

    Background Individuals with non-fluent aphasia have difficulty producing syntactically laden words, such as function words, whereas individuals with fluent aphasia often have difficulty producing semantically specific words. It is hypothesised that such dissociations arise, at least in part, from a trade-off between syntactic and semantic sources of input to lexical retrieval. Aims The aims of this study were (a) to identify quantitative measures of the semantic content of narrative for people with aphasia that are reliable indicators of semantic competence, independent of overall aphasia severity; (b) to determine whether these measures distinguish between fluent and non-fluent aphasia; and (c) to assess whether individuals with fluent and non-fluent aphasia show a trade-off between measures of syntactic and semantic production. Methods & Procedures Connected speech samples were elicited from 16 participants with aphasia, 8 fluent and 8 non-fluent. The semantic sufficiency of the samples was analysed by measuring the proportion of correct information units (CIUs), the type–token ratios (TTRs) of content words, and the proportion of semantically specific (“heavy”) to semantically general (“light”) verbs produced. These measures were then correlated with syntactic measures from the QPA (Berndt, Wayland, Rochon, Saffran, & Schwartz, 2000) across and within participant groups. Outcomes & Results CIUs were found to reflect primarily aphasia severity, and not to differentiate between fluent and non-fluent groups. TTRs were also strongly influenced by severity among fluent, but not non-fluent, participants. The ratio of heavy to light verbs reliably distinguished the groups, and showed different patterns of correlation with the syntactic measures. Conclusions Results show some evidence for a trade-off between syntactic and semantic inputs to word retrieval, at least among non-fluent participants. The heavy–light verb ratio provides information about semantic

    Background. Despite a growing clinical need, there are no clear guidelines on assessment of lexical access in the two languages in individuals with bilingual aphasia. Objective. In this study, we examined the influence of language proficiency on three tasks requiring lexical access in English and Spanish bilingual normal controls and in bilingual individuals with aphasia. Methods. 12 neurologically healthy Spanish-English bilinguals and 10 Spanish-English bilinguals with aphasia participated in the study. All participants completed three lexical retrieval tasks: two picture-naming tasks (BNT, BPNT) and a category generation (CG) task. Results. This study found that across all tasks, the greatest predictors for performance were the effect of group and language ability rating (LAR). Bilingual controls had a greater score or produced more correct responses than participants with bilingual aphasia across all tasks. The results of our study also indicate that normal controls and bilinguals with aphasia make similar types of errors in both English and Spanish and develop similar clustering strategies despite significant performance differences between the groups. Conclusions. Differences between bilingual patients and controls demonstrate a fundamental lexical retrieval deficit in bilingual individuals with aphasia, but one that is further influenced by language proficiency in the two languages.

    2015-09-01

    The aim of this article is to review the rationale on which modern aphasia test batteries are based. Since the mid-1950s, a starting point chosen because the discipline of speech (language) pathology was created during that period, a corpus of English aphasia tests was identified through searches of electronic databases. The tests were critically evaluated in terms of their theoretical roots and influences. During the past 50 years, the fundamentals of aphasia assessment remained basically unchanged, that is, to identify and gain insight into the nature and the degree of a language disturbance. However, the way in which the assessment has taken place has shifted back and forth from a purely medical approach to a more neurolinguistic or social approach depending on the influence exerted by different scientific fields. Not a single model on which aphasia assessments rely covers the many and multifaceted problems of individuals with aphasia. At several points in time during the rehabilitation process, the clinician and the patient will encounter a crossroad, where it has to be decided which path to follow next and how to evaluate the covered path. Besides application of formal test batteries, observations in different natural settings, evaluations of functional communication and insights into psychosocial coping contribute towards a holistic approach to aphasia.

    This review of our research with rTMS to treat aphasia contains four parts: Part 1 reviews functional brain imaging studies related to recovery of language in aphasia with emphasis on nonfluent aphasia. Part 2 presents the rationale for using rTMS to treat nonfluent aphasia patients (based on results from functional imaging studies). Part 2 also reviews our current rTMS treatment protocol used with nonfluent aphasia patients, and our functional imaging results from overt naming fMRI scans, obtained pre- and post- a series of rTMS treatments. Part 3 presents results from a pilot study where rTMS treatments were followed immediately by constraint-induced language therapy (CILT). Part 4 reviews our diffusion tensor imaging (DTI) study that examined white matter connections between the horizontal, midportion of the arcuate fasciculus (hAF) to different parts within Broca’s area (pars triangularis, PTr; pars opercularis, POp), and the ventral premotor cortex (vPMC) in the RH and in the LH. Part 4 also addresses some of the possible mechanisms involved with improved naming and speech, following rTMS with nonfluent aphasia patients. PMID:20714075

    To examine community integration and contributing factors in people with aphasia (PWA) following stroke and to investigate the relationship between community integration and quality of life (QOL). Thirty PWA and 42 age-and education-matched control subjects were involved. Main variables were as follows: socioeconomic status, mobility, and activity of daily living (ADL) (Modified Barthel Index), language function [Frenchay Aphasia Screening Test (FAST)], depression [Geriatric Depression Scale (GDS)], Community Integration Questionnaire (CIQ) and Stroke and Aphasia Quality of Life Scale-39 (SAQOL-39). Differences between aphasia and control groups and factors affecting community integration and QOL were analyzed. Home and social integration and productive activity were significantly decreased in the aphasia group compared to the control group; 8.5 and 18.3 points in total CIQ score, respectively. Amount of time spent outside the home and frequency of social contact were also significantly reduced in the aphasia group. Total mean score on the SAQOL-39 was 2.75±0.80 points and was significantly correlated with economic status, gait performance, ADL, depressive mood, and social domain score on the CIQ. Depression score measured by GDS was the single most important factor for the prediction of QOL, but the FAST score was significantly correlated only with the communication domain of the SAQOL-39. Community activities of PWA were very limited, and depression was highly associated with decreased community integration and QOL. Enhancing social participation and reducing emotional distress should be emphasized for rehabilitation of PWA.

    Purpose Script training for aphasia involves repeated practice of relevant phrases and sentences that, when mastered, can potentially be used in other communicative situations. Although an increasingly popular approach, script development can be time-consuming. We provide a detailed summary of the evidence supporting this approach. We then describe a method in which scripts at various levels of difficulty are created by systematically manipulating readability and grammatical and semantic components. We assess the appropriateness of using these template–based scripts with persons with aphasia of differing severities. Method We evaluated the oral reading performance of eight individuals with chronic non-fluent aphasia on scripts developed from the templates. Scripts were either of high or low difficulty relative to their aphasia severity, and personalized by inserting the participant’s town and the name of an acquaintance. Oral reading probes were taken on three separate days within a week and performance within and across participants was examined. Results Regardless of the participant’s aphasia severity, scripts in the low-difficulty condition were read with significantly greater accuracy than scripts in the high-difficulty condition. Discussion These findings support the use of graded script templates to ensure that appropriately challenging scripts are delivered to persons with aphasia for both clinical practice and research.

    The logopenic variant of primary progressive aphasia is a syndrome with neuropsychological and linguistic specificities, including phonological loop impairment for which diagnosis is currently mainly based on the exclusion of the two other variants, semantic and nonfluent/agrammatic primary progressive aphasia. The syndrome may be underdiagnosed due (1) to mild language difficulties during the early stages of the disease or (2) to being mistaken for mild cognitive impairment or Alzheimer's disease when the evaluation of episodic memory is based on verbal material and (3) finally, it is not uncommon that the disorders are attributed to psychiatric co-morbidities such as, for example, anxiety. Moreover, compared to other variants of primary progressive aphasia, brain abnormalities are different. The left temporoparietal junction is initially affected. Neuropathology and biomarkers (cerebrospinal fluid, molecular amyloid nuclear imaging) frequently reveal Alzheimer's disease. Consequently this variant of primary progressive aphasia does not fall under the traditional concept of frontotemporal lobar degeneration. These distinctive features highlight the utility of correct diagnosis, classification, and use of biomarkers to show the neuropathological processes underlying logopenic primary progressive aphasia. The logopenic variant of primary progressive aphasia is a specific form of Alzheimer's disease frequently presenting a rapid decline; specific linguistic therapies are needed. Further investigation of this syndrome is needed to refine screening, improve diagnostic criteria and better understand the epidemiology and the biological mechanisms involved.

    Two cases of aphasia after right hemispheric stroke in right handed patients are described. The first patient had a severe mixed transcortical aphasia, apraxia and neglect after a lesion involving the right lenticular nucleus and periventricular white matter; aphasia was still present after three months. The second patient had a mild, transient fluent aphasia after a small right hemispheric periventricular lesion. Studies with [18F]FDG and positron emission tomography (PET) showed functional depression extending to the structurally unaffected left hemisphere in both patients in the acute stage. After three months, in the patient with persistent aphasia, metabolism was still reduced in the right hemisphere, with some recovery of hypometabolism on the left, while metabolic values had returned to normal in the patient with full language recovery. A close parallelism between glucose metabolism and clinical course in crossed aphasia is shown, as well as the presence of a functional involvement of the structurally unaffected left hemisphere in the acute stage.

  18. Some early cases of aphasia and the capacity to sing.

    PubMed

    Johnson, Julene K; Graziano, Amy B

    2015-01-01

    This chapter examines early cases of aphasia that include observations of the capacity to sing. Although the majority of these cases were published in the late nineteenth century, earlier reports exist and provide insights into the early thinking about the capacity to sing in aphasia, a topic that continues to the present day. The observation that some patients with aphasia and limited speech output were able to sing the texts of songs inspired scholars to examine the relationship between music and language. Early ideas about the capacity to sing were provided by well-known neurologists, such as John Hughlings Jackson and Adolf Kussmaul. The work of Herbert Spencer about the origins and function of music heavily influenced Jackson and others in their thinking about aphasia. This work also led to an increased interest in understanding music abilities in persons with aphasia and, later, in the brain mechanisms of music. The chapter provides a background as to why there was an interest in the capacity to sing in persons with aphasia and what influenced early thinking on this topic.

    In the clinical routine examination of patients with brain tumors, aphasic symptoms are often not recognized. In order to document the incidence of such symptoms, three diagnostic methods of testing for aphasia were compared: the Aachen aphasia test (AAT), which is the German standard aphasia test, clinical examination, and the Aachen aphasia bedside test (AABT), which was designed to test patients in the acute phases of illness. In the AAT, 50% of patients with left-sided tumors and 36% of those with right-sided tumors showed aphasic disturbances. The AAT results were defined as the gold standard. Clinical examination showed only low sensitivity; less than half of the aphasic patients were diagnosed as such. The AABT also detected only about half of the patients with aphasic disturbances. The low sensitivity is caused mainly by the results of the patients with right-hemisphere tumors, in which the mental set of the examiner during clinical examination (aphasic symptoms are not expected in patients with right-hemisphere lesions) and the pattern of disturbances in the AABT (deficits may be less severe and different in nature) may prevent detection of aphasic symptoms. Both clinical examination and AABT are thus not suitable for aphasia diagnostics in brain tumor patients. As the AAT is very time-consuming in everyday clinical routine, however, the development of an aphasia screening test seems desirable.

    Background Primary progressive aphasia (PPA) is a progressive disorder of language that is increasingly recognised as an important presentation of a specific spectrum of neurodegenerative conditions. Aims In an era of etiologically specific treatments for neurodegenerative conditions, it is crucial to establish the histopathologic basis for PPA. In this review, I discuss biomarkers for identifying the pathology underlying PPA. Main Contribution Clinical syndromes suggest a probabilistic association between a specific PPA variant and an underlying pathology, but there are also many exceptions. A considerable body of work with biomarkers is now emerging as an important addition to clinical diagnosis. I review genetic, neuroimaging and biofluid studies that can help determine the pathologic basis for PPA. Conclusions Together with careful clinical examination, there is great promise that supplemental biomarker assessments will lead to accurate diagnosis of the pathology associated with PPA during life and serve as the basis for clinical trials in this spectrum of disease.

    We report the case of a 16-year-old right-handed Chinese/English bilingual patient who developed herpes simplex encephalitis involving the left temporal lobe, with resultant aphasia. His native language was Mandarin, but he had received extensive training in English for 6 years after moving to the United States and was fluent in English. One week after admission, he could not speak, comprehend, repeat, name, read, or write in English, but he had relative preservation of most of these facilities in Mandarin. He could not write in Mandarin, and his syntax was simplified. Two months later, along with intensive bilingual speech therapy, his reading, writing, and naming in English had almost recovered.

  2. Asymmetric inhibitory treatment effects in multilingual aphasia.

    PubMed

    2013-01-01

    Findings from recent psycholinguistic studies of bilingual processing support the hypothesis that both languages of a bilingual are always active and that bilinguals continually engage in processes of language selection. This view aligns with the convergence hypothesis of bilingual language representation. Furthermore, it is hypothesized that when bilinguals perform a task in one language they need to inhibit their other, nontarget language(s) and that stronger inhibition is required when the task is performed in the weaker language than in the stronger one. The study of multilingual individuals who acquire aphasia resulting from a focal brain lesion offers a unique opportunity to test the convergence hypothesis and the inhibition asymmetry. We report on a trilingual person with chronic nonfluent aphasia who at the time of testing demonstrated greater impairment in her first acquired language (Persian) than in her third, later learned language (English). She received treatment in English followed by treatment in Persian. An examination of her connected language production revealed improvement in her grammatical skills in each language following intervention in that language, but decreased grammatical accuracy in English following treatment in Persian. The increased error rate was evident in structures that are used differently in the two languages (e.g., auxiliary verbs). The results support the prediction that greater inhibition is applied to the stronger language than to the weaker language, regardless of their age of acquisition. We interpret the findings as consistent with convergence theories that posit overlapping neuronal representation and simultaneous activation of multiple languages and with proficiency-dependent asymmetric inhibition in multilinguals.

    Background The efficacy of telerehabilitation-based treatment for anomia has been demonstrated in post-stroke aphasia, but the efficacy of this method of anomia treatment delivery has not been established within the context of degenerative illness. Aims The current study evaluated the feasibility and efficacy of a telerehabilitation-based approach to anomia treatment within the three subtypes of primary progressive aphasia (PPA). Methods & Procedures Each of the three telerehabilitation participants represented a distinct subtype of PPA. Following a baseline evaluation of language and cognition, a phonological treatment and an orthographic treatment were administered to all participants over the course of six months. One month after the end of treatment, a post-treatment evaluation began. All treatment sessions and the majority of the evaluation sessions were administered via telerehabilitation. Treatment effects were examined within each subject, and treatment effects were also compared between each telerehabilitation participant and a group of in-person participants who had the same subtype of PPA. Outcomes & Results All three telerehabilitation participants exhibited positive treatment effects. CGR (nonfluent/agrammatic variant PPA) and WCH (logopenic variant PPA) showed maintenance of naming for prophylaxis items in both treatment conditions, while ACR (semantic variant PPA) demonstrated increased naming of remediation items in the phonological treatment condition. Compared to in-person participants with the same subtype of PPA, each of the telerehabilitation participants typically showed effects that were either within the expected range or larger than expected. Conclusions Telerehabilitation-based anomia treatment is feasible and effective in all three subtypes of PPA. PMID:27087732

    Few studies have assessed the relationship between aphasia and rehabilitation length of stay (LOS). The aim of the current prospective study was to evaluate LOS in patients with aphasia and its relation to functional improvement. The study was performed in 252 patients admitted for rehabilitation follow-up of their first stroke (126 patients with aphasia and hemiparesis [aphasia group] and 126 patients with hemiparesis but without aphasia [control group]). All patients were submitted to clinical, neurological, and neuropsychological examinations. The following tests were performed: Aachen Aphasia Test, Albert's test, anosognosia scale, Cumulative Illness Rating Scale (CIRS), Fugl-Meyer Scale, and FIM. LOS was 50.7 and 46.7 days in the aphasia and control groups, respectively. There was no statistically significant difference in the LOS between aphasia and control groups (p = .056). A longer LOS was correlated with low admission aphasia score (r = -0.19). The increase in motor FIM per day obtained by therapy (LOS-Eff) was 0.54 +/- 0.3 in the aphasia group and 0.75 +/- 0.5 in the control group. The LOS-Eff was significantly poorer in the aphasia group (p = .000). A high LOS-Eff was correlated with high aphasia score (r = 0.31). In multivariate regression analyses, aphasia was an important predictor of LOS-Eff (beta = 0.18). In patients with aphasia, LOS is few days longer and LOS-Eff is significantly poorer compared to patients without aphasia. Aphasia is a significant independent predictor of LOS-Eff at discharge.

    Background General agreement exists in the literature that individuals with aphasia can exhibit a working memory deficit that contributes to their language processing impairments. Though conceptualized within different working memory frameworks, researchers have suggested that individuals with aphasia have limited working memory capacity, impaired attention-control processes as well as impaired inhibitory mechanisms. However, across studies investigating working memory ability in individuals with aphasia, different measures have been used to quantify their working memory ability and identify the relationship between working memory and language performance. Aims The primary objectives of this article are to (1) review current working memory theoretical frameworks, (2) review tasks used to measure working memory, and (3) discuss findings from studies that have investigated working memory as they relate to language processing in aphasia. Main Contribution Though findings have been consistent across studies investigating working memory ability in individuals with aphasia, discussion of how working memory is conceptualized and defined is often missing, as is discussion of results within a theoretical framework. This is critical, as working memory is conceptualized differently across the different theoretical frameworks. They differ in explaining what limits capacity and the source of individual differences as well as how information is encoded, maintained, and retrieved. When test methods are considered within a theoretical framework, specific hypotheses can be tested and stronger conclusions that are less susceptible to different interpretations can be made. Conclusions Working memory ability has been investigated in numerous studies with individuals with aphasia. To better understand the underlying cognitive constructs that contribute to the language deficits exhibited by individuals with aphasia, future investigations should operationally define the cognitive

    A diverse literature addresses elements of conversation therapy in aphasia including intervention rooted in conversation analysis, partner training, group therapy and behavioural intervention. Currently there is no resource for clinicians or researchers that defines and organizes this information into a coherent synopsis describing various conversation therapy practices. To organize information from varied sources into a descriptive overview of conversation therapy for aphasia. Academic search engines were employed to identify research articles published between 1950 and September 2013 reporting on conversation therapy for aphasia. Thirty articles met criteria for review and were identified as primary sources for the qualitative review. Using qualitative methodology, relevant data were extracted from articles and categories were identified to create a descriptive taxonomy of conversation therapy for aphasia. Conversation interventions were divided into descriptive categories including: treatment participants (person with aphasia, partner, dyad), primary guiding orientation (conversation analysis, social model, behavioural, relationship centred), service delivery (individual, group), focus of intervention (generic/individualized; problem/solution oriented; compensatory), training methods (explicit/implicit; external/embedded), activities or tasks, and outcomes measured. Finally, articles were categorized by research design. There was marked variation in conversation therapy approaches and outcome measures reported and a notable gap in information about one-on-one conversation therapy for individuals with aphasia. This review provides a description of various conversation therapy approaches and identified gaps in the existing literature. Valid measures of natural conversation, research on one-on-one conversation approaches for individuals with aphasia, and a systematic body of evidence consisting of high quality research are needed. © 2014 Royal College of Speech

    Background Quality of life (QL) can be defined as the individual’s perception of their own well-being. Aphasia is the most important potential consequence of stroke and has a profound effect on a patient’s life, causing emotional distress, depression, and social isolation, due to loss of language functions. Aims To draw up a QL questionnaire for aphasics (QLQA) focusing particularly on difficulties in interpersonal relationships and on the loss of independence as a result of language disorders. We reported the results of a psychometric evaluation of this measure. Moreover, we experimentally focused on the differences in QLQA between patients affected only by neurological motor impairment and hemiparetic patients with aphasia (PWA) in order to verify the specific role of aphasia on QL. We also explored if the QLQA is sensitive to the severity of aphasia and to the time elapsing from the stroke. Methods A total of 146 consecutive PWA and 37 control subjects were enrolled to evaluate the reliability (internal consistency and test–retest reliability) and validity of the QLQA, using standard psychometric methods. Patients were divided into acute (within 3 months since stroke) and chronic (beyond 3 months) groups, and into mild and severe according to the severity of aphasia. The experimental group of only acute PWA was compared to control subjects, with right hemispherical lesion and without aphasia in QLQA total and partial scores. Results The QLQA had good internal consistency and test–retest reliability. Acute and chronic PWA and mild and severe ones differed in QLQA total, communication, and autonomy subscales. No differences were found in psychological condition. Between aphasic and control patients, significant differences were found in all QLQA subscales. Conclusion The QLQA is a valid measure of QL in PWA, contributing to a better distinction between severe and mild aphasia, and it is sensitive also to the variations in QL depending on the time interval

    With the Meta-analysis method, the clinical efficacy of acupuncture and other regular methods for aphasia was evaluated, and the acupoints selection for aphasia was explored. The acupuncture literature of clinical randomized control trials for aphasia published in CNKI, WANFANG, VIP and CBM database was searched; the statistical analysis of clinical efficacy of acupuncture and other regular methods for aphasia was performed by using software Revman 5. 2 provided by Cochrane library. A file of Microsoft Excel was established to perform the analysis of acupoints selection based on frequency analysis method, so as to summarize the characteristics and rules. Totally 385 articles were searched, and 37 articles those met the inclusive criteria was included, involving 1,260 patients in the acupuncture group and 1 238 patients in the control group. The Meta-analysis results showed OR = 3.82, 95% Cl [3.01, 4.85]; rhombus was located on the right side and the funnel plot was nearly symmetry, indicating the treatment effect of the acupuncture group for aphasia was superior to the control group (Z = 11.04, P < 0.000 01). The frequency-analysis results showed that the frequency of acupoints from top to bottom was Lian-quan (CV 23), Tongli (HT 5), Yamen (GV 15), Jinjin (EX-HN 12), Yuye (EX-HN 13), Baihui (GV 20), Yuyan II, Yuyan I and Yuyan III. The frequency of meridians from top to bottom was the governor vessel, extra channels, conception vessel, heart meridian and large intestine meridian. It is concluded that the clinical efficacy of acupuncture combined with speech rehabilitation training and medication treatment for aphasia is superior to that of speech rehabilitation training and medication treatment alone. The clinical treatment for aphasia focuses on its local effect; the main acupoints are in the head and face, and the meridians are governor vessel, extra channels and conception vessel.

    Lesions to Broca's area cause aphasia characterized by a severe impairment of the ability to speak, with comparatively intact speech perception. However, some studies have found effects on speech perception under adverse listening conditions, indicating that Broca's area is also involved in speech perception. While these studies have focused on auditory speech perception other studies have shown that Broca's area is activated by visual speech perception. Furthermore, one preliminary report found that a patient with Broca's aphasia did not experience the McGurk illusion suggesting that an intact Broca's area is necessary for audiovisual integration of speech. Here we describe a patient with Broca's aphasia who experienced the McGurk illusion. This indicates that an intact Broca's area is not necessary for audiovisual integration of speech. The McGurk illusions this patient experienced were atypical, which could be due to Broca's area having a more subtle role in audiovisual integration of speech. The McGurk illusions of a control subject with Wernicke's aphasia were, however, also atypical. This indicates that the atypical McGurk illusions were due to deficits in speech processing that are not specific to Broca's aphasia. PMID:25972819

    We present a case study of a woman who used yogic breathing as Ayurvedic medicine in her recovery from poststroke aphasia. Ayurvedic medicine is one of the most ancient medicines of the world, but it is not widely used for aphasia rehabilitation in many Western countries. The description of this case aims to further the understanding of the benefits that this type of medicine may provide to poststroke patients living with aphasia. After her stroke, the patient received brief conventional language therapy for her aphasia. At 5 weeks post stroke, she received no further conventional rehabilitation; instead, she consulted with a Vedic priest. She followed a regimen of different body manipulations, yogic breathing techniques, and ingestion of coconut oil. Cognitive and language testing was performed throughout a 3-month period while she was involved in this therapy. Overall, improvement was noted in language, visual attention, and some mood measures. Although case studies lead to limited conclusions, changes were observed for this individual using Ayurvedic medicine. Given the changes in language and some aspects of cognition seen in this patient, further exploration of the effectiveness of yogic breathing and Ayurvedic medicine in the treatment of poststroke aphasia is warranted.

    Ictal aphasia in adults is a rare phenomenon. Most reported cases manifest with non-fluent (Broca) aphasia. Ictal fluent (Wernicke) aphasia is less common. We report a 47-year-old, right-handed woman that presented with recurrent episodes of non-convulsive seizures in the form of Wernicke's aphasia for 2 weeks. An MRI of the brain showed an old cerebral infarction in the left parieto-occipital area. Scalp EEG revealed continuous periodic sharp waves at the left temporal regions with diffusion to the whole left hemisphere and at occasions to the right. This is followed by variable periods of post ictal slowing. Recurrence of the described ictal pattern was noted. Management of status epilepticus was started in the form of intravenous diazepam and a loading dose of phenytoin and phenobarbitone. After treatment, she improved clinically and the EEG improved with disappearance of the left temporal ictal rhythm and normalization of the EEG background. Thus, establishing the diagnosis of non-convulsive partial status epilepticus manifesting as ictal aphasia.

    An historical overview is presented that focuses on the changes both in approach and topics with respect to language disturbances due to brain lesions. Early cases of language disorders were described without any theorizing about language or its relation to the brain. Also, three forms of speech disorder were distinguished: traulotes, psellotes and ischophonia, which are only marginally related to aphasia. In the 18th century some authors, in particular Gesner and Crichton, attempted to explain language disorders in terms of mental processes. The great debate on both the anatomical (Broca, Wernicke) and functional (Wernicke, Lichtheim) aspects of aphasia dominated late 19th century discussion of localization of function, leading to the development of what we now call the cognitive neurosciences. In this period, language processing was described in terms of a simple functional model of word recognition and production; linguistic principles played no role. At the beginning of the 20th century the discussion on language disorders waned due to a decrease of interest in the issue of localization; aphasia became primarily a clinical issue of how best to classify patients. In the second half of the 20th century, the field of aphasia developed rapidly due to studies performed at the Boston Aphasia Unit and, more importantly, to a change of orientation to linguistic notions of language structure, as introduced by Chomsky.

    Objectives Individuals with nonfluent agrammatic aphasia show impaired production and comprehension of time reference via verbal morphology. However, cross-linguistic findings to date suggest inconsistent evidence as to whether tense processing in general is impaired or time reference to the past is selectively difficult in this population. This study examined production and comprehension of time reference via verb morphology in Korean-speaking individuals with nonfluent aphasia. Methods A group of 9 healthy controls and 8 individuals with nonfluent aphasia (5 for the production task) participated in the study. Sentence priming production and auditory sentence to picture matching tasks were used, parallel with the previous cross-linguistic experiments in English, Chinese, Turkish, and others. Results The participants with nonfluent aphasia showed different patterns of impairment in production and comprehension. In production, they were impaired in all time references with errors being dominated by substitution of incorrect time references and other morpho-phonologically well-formed errors, indicating a largely intact morphological affixation process. In comprehension, they showed selective impairment of the past, consistent with the cross-linguistic evidence from English, Chinese, Turkish, and others. Conclusion The findings suggest that interpretation of past time reference poses particular difficulty in nonfluent aphasia irrespective of typological characteristics of languages; however, in production, language-specific morpho-semantic functions of verbal morphology may play a significant role in selective breakdowns of time reference.

    INTRODUCTION. Language assessment in persons with brain injury makes it possible to know whether they require language rehabilitation or not. Given the importance of a precise evaluation, assessment instruments must be valid and reliable, so as to avoid mistaken and subjective diagnoses. AIM. To validate 'lexical screening for aphasias' in a sample of 58 Chilean individuals. SUBJECTS AND METHODS. A screening-type language test, lasting 20 minutes and based on the lexical processing model devised by Patterson and Shewell (1987), was constructed. The sample was made up of two groups containing 29 aphasic subjects and 29 control subjects from different health centres in the regions of Biobio and Maule, Chile. Their ages ranged between 24 and 79 years and had between 0 and 17 years' schooling. Tests were carried out to determine discriminating validity, concurrent validity with the aphasia disorder assessment battery, reliability, sensitivity and specificity. RESULTS. The statistical analysis showed a high discriminating validity (p < 0.001), an acceptable mean concurrent validity with aphasia disorder assessment battery (rs = 0.65), high mean reliability (alpha = 0.87), moderate mean sensitivity (69%) and high mean specificity (86%). CONCLUSION. 'Lexical screening for aphasias' is valid and reliable for assessing language in persons with aphasias; it is sensitive for detecting aphasic subjects and is specific for precluding language disorders in persons with normal language abilities.

    Stroke is the leading cause of disability in many countries. Aphasia is a common sign of stroke that is observed in about one-third of stroke patients and contributes to disease morbidity. However, the relationship between anatomy and different forms of aphasia remains poorly understood. We intend to study the characteristics of aphasia in the acute stage of stroke and to identify neuroanatomical correlates using MRI. Lesion sites were selected from 1198 patients with cerebral infarction, who were hospitalized in the stroke unit of our hospital between March 2002 and March 2006. We enrolled 325 patients who fulfilled our criteria. All patients received an MRI examination within 1 week after admission and were evaluated with the Western battery aphasia (WAB) test, in order to determine what type of aphasia they had. The severity of their language deficit was further classified using the Boston diagnostic aphasia examination (BDAE) severity grading standard. Among 1198 cases, five cases with Broca's areas and four cases with Wernicke's areas lesions on MRI works were free of language deficits. Within the 325 patients who demonstrated clinical signs of aphasia, the results of WAB showed that there were 83 Broca' aphasia cases, 48 Wernicke's aphasia cases, 12 conduction aphasia cases, 36 transcortical motor aphasia cases, 17 transcortical sensory aphasia cases, 19 transcortical mixed aphasia cases, 58 global aphasia cases and 52 anomic aphasia cases. Two hundred and eighty-eight cases were located within classical language centers while 37 cases were located at other sites. In 325 aphasia patients with grade criteria of BDAE of grades 0, 1, 2, 3 or 4, there were 84, 79, 77, 63 and 22 cases respectively. Many of cases with grades 0 and 1 were distributed within classical language centers. This study showed that it is possible to draw a neuroanatomical map of aphasia that encompasses the 95% of aphasia cases. It also demonstrates that the main determinant of aphasic

    Post-stroke patients with aphasia have higher levels of psychological distress. We aimed to find the relation between post-stroke aphasia and depression, anxiety and personality traits. One month after stroke, 61 consecutive patients with stroke were included in this study. Thirty post-stroke patients with aphasia and 31 patients without aphasia. We used the following scales a clinical-friendly: Aphasic test, Eysenck Personality Questionnaire, Hamilton anxiety and Beck Depression Inventory. Depression and anxiety were more prominent among patients with aphasia than stroke without aphasia. Psychosis was more prominent among post-stroke patients with aphasia. Our results may not exclusively exclude pre-morbid personality traits. Our study highlights the growing need to develop community rehabilitation services in the developing world, which address both physical and psychological morbidity. Copyright © 2014 Elsevier B.V.

    Aphasia is a rare neurologic disorder in childhood. Nevertheless some authors believe that some subtle aphasic syndromes as anomic aphasia are not always identified and the real prevalence of aphasia in childhood is higher. We observed a case of aphasia during the acute period of Herpes Simplex Encephalitis in a 5 years old, right handed, boy with a good level of fluent speech. Six weeks after his initial assessment language was spontaneous, fluent, with normal prosodhy and articulation, but reduced, without content words, with frequent circunlocutory speech, semantic paraphasias, anomic latencies, real anomias, "pass partout" words. This picture was suggestive for anomic aphasia in a normally fluent context. Anomic aphasia can be produced by the disconnection between cortical and subcortical systems. Documented cases of anomic aphasia in childhood are rare. Our case present great similarities with adult cases in terms of localisation and denomination difficulties.

    We investigated whether primary progressive aphasias (PPA) reflect non-random degradation of linguistic dimensions that might be supported by different neural subsystems and to what extent this degradation contributes to the emergence of clinical entities: semantic (S), logopenic (L) and nonfluent (NF) aphasia; apraxia of speech was also considered if associated with language disorders (AOS/aph). Forty-two aphasic patients are reported. Two main definable patterns of linguistic deficits tended to emerge that corresponded with identifiable patterns of brain atrophy, and probably diseases: the S variant, which principally expresses the impact of a "deep" cognitive (semantic) disorder on language, and AOS/aph in which "peripheral" executive components play a significant role. By contrast, NF aphasia emerged as a heterogeneous variant due to disorganization of various dimensions within the linguistic domain, that assumes different patterns depending on the differential distribution of atrophy in the perisylvian regions.

    OBJECTIVE Dopaminergic agents may stimulate behavior and verbal expression after frontal lobe dysfunction. Although amantadine is used in neurorehabilitation of motivational disorders and head injury, it is not commonly prescribed to improve aphasia. This pilot study examined verbal fluency on and off amantadine for nonfluent speech. DESIGN Four participants undergoing inpatient rehabilitation, meeting criteria for transcortical motor aphasia had stroke (2), stroke post-aneurysm surgery (1), or brain tumor resection (1). We administered amantadine 100 mg bid in an open-label, on-off protocol with multiple assessments per on-off period. RESULTS Off medication, subjects generated a mean 12.62 words (abnormally few) on the Controlled Oral Word Association test. On medication, word generation significantly improved to 17.71 words (p = 0.04), although scores remained psychometrically in the abnormal range. CONCLUSIONS Further research on amantadine specifically for nonfluent speech and nonfluent aphasia, including effect on functional communication and control conditions, may be warranted.

    Two patients with tactile naming disorders are reported. Case 1 (right hand tactile agnosia due to bilateral cerebral infarction) differentiated tactile qualities of objects normally, but could neither name nor categorize the objects. Case 2 (bilateral tactile aphasia after operation of an epidural left parietal haematoma) had as severe a tactile naming disturbance as Case 1, but could categorize objects normally, demonstrating that tactile recognition was preserved. Case 1 may be the first case of tactile agnosia clearly differentiated from tactile aphasia. CT scans of Case 1 revealed lesions in the left angular gyrus, and in the right parietal, temporal, and occipital lobes. Case 2 had lesions in the left angular gyrus and of posterior callosal radiations. Our findings suggest that tactile agnosia appears when the somatosensory association cortex is disconnected by a subcortical lesion of the angular gyrus from the semantic memory store located in the inferior temporal lobe, while tactile aphasia represents a tactual-verbal disconnection.

    Positron emission computed tomography (PECT) using 18F-2-fluoro-2-deoxy-D-glucose (FDG) was used to investigate the correlations between clinical status, anatomy (as described by CT), and metabolism in five patients with stable aphasia resulting from ischemic cerebral infarction. Local cerebral metabolic activity was diminished in an area larger than the area of infarction demonstrated by CT. In one patient, FDG PECT revealed a metabolic lesion that probably caused the aphasic syndrome and was not apparent by CT. The data suggest that reliance on CT in delineating the extent of the brain lesion in aphasia or other neuropsychological defects can be misleading; FDG PECT may provide important additional information. Two patients with similar metabolic lesions had very different clinical syndromes, showing that even when currently available methods are combined, major gaps remain in clinicoanatomical correlations in aphasia.

    Primary progressive aphasia (PPA) corresponds to the gradual degeneration of language which can occur as nonfluent/agrammatic PPA, semantic variant PPA or logopenic variant PPA. We describe the clinical evolution of a patient with PPA presenting jargon aphasia as a late feature. At the onset of the disease (ten years ago) the patient showed anomia and executive deficits, followed later on by phonemic paraphasias and neologisms, deficits in verbal short-term memory, naming, verbal and semantic fluency. At recent follow-up the patient developed an unintelligible jargon with both semantic and neologistic errors, as well as with severe deficit of comprehension which precluded any further neuropsychological assessment. Compared to healthy controls, FDG-PET showed a hypometabolism in the left angular and middle temporal gyri, precuneus, caudate, posterior cingulate, middle frontal gyrus, and bilaterally in the superior temporal and inferior frontal gyri. The clinical and neuroimaging profile seems to support the hypothesis that the patient developed a late feature of logopenic variant PPA characterized by jargonaphasia and associated with superior temporal and parietal dysfunction.

    Background Among the obstacles to demonstrating efficacy of pharmacological intervention for aphasia is quantifying patients’ responses to treatment in a statistically valid and reliable manner. In many of the review papers on this topic (e.g., Berthier et al., 2011; de Boissezon, Peran, de Boysson, & Démonet, 2007; Small & Llano, 2009), detailed discussions of various methodological problems are highlighted, with some suggestions on how these shortcomings should be addressed. Given this deep understanding of caveats associated with the experimental design of aphasia pharmacotherapy studies (e.g., Berthier et al., 2011), investigations continue to produce inconsistent results. Aim In this review paper we suggest that inclusion of theory-driven linguistic measures in aphasia pharmacotherapy studies would add an important step toward elucidating precise patterns of improvement in language performance resulting from pharmacotherapeutic intervention. Main Contribution We provide a brief review of the clinical approaches currently used in pharmacotherapy studies of aphasia, which often lack psycholinguistic grounding. We then present ways in which psycholinguistic models can complement this approach, offering a rationale for task selection, and as a result, lead to a better understanding of treatment effects. We then follow with an example of how such an integrative approach can be implemented in studies targeting stress reduction in people with aphasia, via beta-blocking agents, as a means to augment language performance, using the psycholinguistic framework of “linguistic anxiety” outlined in Cahana-Amitay et al, 2011 as our guideline. Conclusion We conclude that the incorporation of psycholinguistic models into aphasia pharmacotherapy studies can increase the resolution with which we can identify functional changes. PMID:24489425

    Purpose To examine community integration and contributing factors in people with aphasia (PWA) following stroke and to investigate the relationship between community integration and quality of life (QOL). Materials and Methods Thirty PWA and 42 age-and education-matched control subjects were involved. Main variables were as follows: socioeconomic status, mobility, and activity of daily living (ADL) (Modified Barthel Index), language function [Frenchay Aphasia Screening Test (FAST)], depression [Geriatric Depression Scale (GDS)], Community Integration Questionnaire (CIQ) and Stroke and Aphasia Quality of Life Scale-39 (SAQOL-39). Differences between aphasia and control groups and factors affecting community integration and QOL were analyzed. Results Home and social integration and productive activity were significantly decreased in the aphasia group compared to the control group; 8.5 and 18.3 points in total CIQ score, respectively. Amount of time spent outside the home and frequency of social contact were also significantly reduced in the aphasia group. Total mean score on the SAQOL-39 was 2.75±0.80 points and was significantly correlated with economic status, gait performance, ADL, depressive mood, and social domain score on the CIQ. Depression score measured by GDS was the single most important factor for the prediction of QOL, but the FAST score was significantly correlated only with the communication domain of the SAQOL-39. Conclusion Community activities of PWA were very limited, and depression was highly associated with decreased community integration and QOL. Enhancing social participation and reducing emotional distress should be emphasized for rehabilitation of PWA. PMID:26446656

    In the past verb retrieval problems were associated primarily with agrammatism and noun retrieval difficulties with fluent aphasia. With regards to fluent aphasia, so far in the literature, three distinct patterns of verb/noun dissociations have been described for individuals with fluent anomic aphasia in languages with different underlying forms; better verb retrieval, poorer verb retrieval and equal retrieval difficulties for verbs and nouns. Verbs and nouns in Greek are considered of similar morphological complexity thus it was predicted that anomic aphasic individuals would suffer from a non-dissociated impairment of verbs and nouns. Problems with verbs and/or nouns may arise at any stage in the process of lexical retrieval, i.e. lexical-semantic, lemma, lexeme or articulation. The aim of this research was to investigate verb and noun retrieval using a picture-naming task to explore any possible selective noun and/or verb comprehension or retrieval deficits in Greek individuals with anomic aphasia. The results revealed a significant verb/noun dichotomy with verbs significantly more difficult to retrieve than nouns. These findings lend support for the growing body of evidence showing a specific verb impairment in fluent anomic individuals as well as Broca's patients. Given the prevailing view, that anomic patients experience difficulty retrieving the morpho-phonological form of the target word, the results show that specific information of the grammatical category is also important during word form retrieval. LEARNER OUTCOMES: The reader will become familiar with (i) studies investigating grammatical word class breakdown in individuals with aphasia who speak different languages, (ii) the application of the serial model to word production breakdown in aphasia and (iii) the characteristics of verbs and nouns in Greek. It will be concluded that successful verb retrieval for fluent aphasic individuals who speak Greek is dependant on the retrieval of the morpho

    People with agrammatic aphasia often experience greater difficulty comprehending passive compared to active sentences. The Trace Deletion Hypothesis (TDH; Grodzinsky, 2000) proposes that aphasic individuals cannot generate accurate syntactic representations of passive sentences and, hence, use an agent-first processing strategy which leads to at-chance performance. We tested this claim using the eyetracking-while-listening paradigm in order to reveal online processing routines. Ten agrammatic aphasic participants and 10 age-matched controls listened to passive and active sentences and performed a sentence-picture matching task (i.e., selecting between two pictures with reversed thematic roles), while their eye movements were monitored. Control participants’ performance was at ceiling, whereas accuracy for the aphasic participants was above chance for active sentences and at chance for passive sentences. Further, for the control participants, the eye movement data showed an initial agent-first processing bias, followed by fixation on the correct picture in the vicinity of the verb in both active and passive sentences. However, the aphasic participants showed no evidence of agent-first processing, counter the predictions of the TDH. In addition, in active sentences, they reliably fixated the correct picture only at sentence offset, reflecting slowed processing. During passive sentence processing, fixations were at chance throughout the sentence, but different patterns were noted for correct and incorrect trials. These results are consistent with the proposal that agrammatic sentence comprehension failure involves lexical processing and/or lexical integration deficits. PMID:22043134

    Despite the ubiquity of inner speech in our mental lives, methods for objectively assessing inner speech capacities remain underdeveloped. The most common means of assessing inner speech is to present participants with tasks requiring them to silently judge whether two words rhyme. We developed a version of this task to assess the inner speech of a population of patients with aphasia and corresponding language production deficits. Patients’ performance on the silent rhyming task was severely impaired relative to controls. Patients’ performance on this task did not, however, correlate with their performance on a variety of other standard tests of overt language and rhyming abilities. In particular, patients who were generally unimpaired in their abilities to overtly name objects during confrontation naming tasks, and who could reliably judge when two words spoken to them rhymed, were still severely impaired (relative to controls) at completing the silent rhyme task. A variety of explanations for these results are considered, as a means to critically reflecting on the relations among inner speech, outer speech, and silent rhyme judgments more generally.

    Primary progressive aphasia (PPA) is a clinical syndrome characterised by a progressive decline in language and speech of neurodegenerative origin. Major breakthroughs made in recent years have lent us a better understanding of this syndrome, which may be the first manifestation of any of a number of neurodegenerative diseases. We reviewed the main aspects of PPA epidemiology, clinical manifestations, diagnosis, aetiology and treatment. Most cases manifest sporadically and the typical age of onset is between 50 and 70 years. Three clinically distinct variants have been described: nonfluent or agrammatic PPA, semantic PPA and logopenic PPA. Each of these variants tends to be associated with specific histopathological findings, but clinical diagnostic methods are imperfect predictors of underlying pathology. Anatomical and functional neuroimaging can provide useful biomarkers. Several treatments have been proposed, and while no clear benefits have been demonstrated, acetylcholinesterase inhibitors may be useful, especially in the logopenic variant. PPA is an emerging syndrome which may be more prevalent than we might expect. It was previously listed as part of the frontotemporal dementia spectrum, and it is also related to Alzheimer disease. Clinical diagnosis, complemented by a biomarker evaluation, may predict the underlying pathology, which in turn will improve treatment possibilities. Copyright © 2012 Sociedad Española de Neurología.

  4. The classifier problem in Chinese aphasia.

    In recent years, research on the relationship between brain organization and language processing has benefited tremendously from cross-linguistic comparisons of language disorders among different types of aphasic patients. Results from these cross-linguistic studies have shown that the same aphasic syndromes often look very different from one language to another, suggesting that language-specific knowledge is largely preserved in Broca's and Wernicke's aphasics. In this paper, Chinese aphasic patients were examined with respect to their (in)ability to use classifiers in a noun phrase. The Chinese language, in addition to its lack of verb conjugation and an absence of noun declension, is exceptional in yet another respect: articles, numerals, and other such modifiers cannot directly precede their associated nouns, there has to be an intervening morpheme called a classifier. The appropriate usage of nominal classifiers is considered to be one of the most difficult aspects of Chinese grammar. Our examination of Chinese aphasic patients revealed two essential points. First, Chinese aphasic patients experience difficulty in the production of nominal classifiers, committing a significant number of errors of omission and/or substitution. Second, two different kinds of substitution errors are observed in Broca's and Wernicke's patients, and the detailed analysis of the difference demands a rethinking of the distinction between agrammatism and paragrammatism. The result adds to a growing body of evidence suggesting that grammar is impaired in fluent as well as nonfluent aphasia.

    Acquired aphasia with convulsive disorder is an unusual condition in childhood, characterized by loss of language function associated with a paroxysmal electroencephalogram. To determine the course and outcome of this disorder, we evaluated nine patients 10 to 28 years after the onset of aphasia. Four patients had recovered fully, one had mild language dysfunction, and four had moderate language disability. Four of the five patients with the best outcome had decreased visuoperceptive function as measured by the Revised Benton Visual Retention Test (RBVRT), whereas the three tested patients with moderate language dysfunction had normal RBVRT scores.

    Many individuals with severe aphasia are effective in using nonverbal methods of communication to meet their wants and needs. However, their difficulty lies in conveying specific and novel information. Through the use of augmentative and alternative communication (AAC) techniques, severely aphasie individuals can share unique information during interactions. This article focuses on designing AAC intervention programs based on the individual's residual strengths, communication needs, and treatment setting. Individuals who have suffered brainstem strokes or individuals with dysarthria as the primary factor influencing communication are not discussed. Rather, this articlefocuses on individuals with permanent communication disorders due to severe aphasia.

    This study aims at investigating the production of the Greek modal and negative particles by non-fluent aphasic patients. These particles belong to the highest part of the verb periphrasis, so they are likely to be impaired in non-fluent aphasia, according to some hypotheses about agrammatic language. Moreover, there is an agreement relation between modality and negation, allowing the examination of agreement relationships in the clause domain. The data are compared to the predictions of recent theories on agrammatic language. The data provide evidence that modality is impaired in agrammatic aphasia, whilst agreement relations between clausal elements are spared.

    The effects of the variables age at onset, cause, severity and bilaterality of lesion, and type of aphasia on course and outcome were investigated in a group of 28 aphasic children. Analysis of spontaneous speech and tests of auditory verbal comprehension were used to determine the presence of aphasia. The severity of the cerebral lesion was assessed using a rating scale for computed tomographic scans. Most of the children had not recovered completely 1 year after onset. Recovery was significantly different according to etiological categories. Complete recovery was seen in the majority of traumatic cases.

    Global aphasia without hemiparesis is a rare condition often associated with embolic stroke. Posttraumatic causes have not been reported, in the literature, to our knowledge. We report a 15-year old boy with transient global aphasia without hemiparesis due to blunt head trauma. In our case, clinical findings occurred 1week later following head trauma. Emergence of the symptoms after a period of the first mechanical head trauma, draws attention to the importance of secondary process in traumatic brain injury. Copyright © 2016 Elsevier Ltd.

    The effects of very early aphasia therapy on recovery are equivocal. This article examines predictors of very early aphasia recovery through statistical modeling. This study involved a secondary analysis of merged data from two randomized, single-blind trials conducted in Australian acute and subacute hospitals. Study 1 (n = 59) compared daily therapy to usual ward care for up to 4 weeks poststroke in patients with moderate to severe aphasia. Study 2 (n = 20) compared daily group therapy to daily individual therapy for 20 1-hour sessions over 5 weeks, in patients with mild to severe aphasia. The primary outcome measure was the Western Aphasia Battery Aphasia Quotient (AQ) at therapy completion. This analysis used regression modeling to examine the effects of age, baseline AQ and baseline modified Rankin Scale (mRS), average therapy amount, therapy intensity, and number of therapy sessions on aphasia recovery. Baseline AQ (p = 0.047), average therapy amount (p = 0.030), and baseline mRS (p = 0.043) were significant predictors in the final regression model, which explained 30% (p < 0.001) of variance in aphasia recovery. The amount of very early aphasia therapy could significantly affect communication outcomes at 4 to 5 weeks poststroke. Further studies should include amount of therapy provided to enhance reliability of prognostic modeling in aphasia recovery. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

    Despite the relatively high prevalence of aphasia, research indicates that, world-wide, public awareness of aphasia is lacking. Of the surveys that have been conducted internationally, none has studied the Canadian public's awareness of aphasia. The purpose of the present survey was to assess public awareness and basic knowledge of aphasia of individuals in southern Ontario, Canada. Using the same questionnaire that has been used in other countries, face-to-face surveys were conducted in public places (e.g. parks) at various locations in southern Ontario. Respondents were asked questions pertaining to their awareness and knowledge of aphasia. The number of surveys retained for analysis was 831. In addition to an evaluation of public awareness and knowledge of aphasia, the potential influences of age, gender, and occupation were analysed. For those who had heard of aphasia, questions were asked to determine how or where they had heard of aphasia. Consistent with the literature, overall public awareness and basic knowledge of aphasia in southern Ontario was found to be limited. The factors of age, gender and occupation were found to influence the results. This investigation supports the need for better promotion of aphasia awareness to the public in southern Ontario and, by extension, in Canada.

    [Purpose] This study explored health science students’ perceptions of motor aphasia and sensory aphasia caused by stroke to provide basic material for the improvement of rehabilitation practitioners’ perceptions of aphasia. [Subjects and Methods] The subjects of this study were 642 freshmen and sophomores majoring in health science. Perceptions of aphasia were surveyed on a semantic differential scale using the Anchoring Vignette Method and the difference in perception of the two types of aphasia was analyzed using multi-dimensional scaling. [Results] The analysis revealed that motor aphasia and sensory aphasia have mutually corresponding images. Motor aphasia had high levels of ‘quiet’, ‘passive’ ‘dumb’, ‘unstable’ and ‘gloomy’ images, while sensory aphasia had high levels of ‘noisy’, ‘unstable’, ‘cheerful’, ‘sensitive’, ‘fluctuating in emotions’, ‘active’, ‘dumb’ and ‘gloomy’ images. [Conclusion] A systematic education is required to be implemented in the future to improve health science students’ negative perceptions of the aftereffects of stroke such as aphasia. PMID:27390413

  13. Brain Stimulation and the Role of the Right Hemisphere in Aphasia Recovery.

    PubMed

    2015-11-01

    Aphasia is a common consequence of left hemisphere stroke and causes a disabling loss of language and communication ability. Current treatments for aphasia are inadequate, leaving a majority of aphasia sufferers with ongoing communication difficulties for the rest of their lives. In the past decade, two forms of noninvasive brain stimulation, repetitive transcranial magnetic stimulation and transcranial direct current stimulation, have emerged as promising new treatments for aphasia. The most common brain stimulation protocols attempt to inhibit the intact right hemisphere based on the hypothesis that maladaptive activity in the right hemisphere limits language recovery in the left. There is now sufficient evidence to demonstrate that this approach, at least for repetitive transcranial magnetic stimulation, improves specific language abilities in aphasia. However, the biological mechanisms that produce these behavioral improvements remain poorly understood. Taken in the context of the larger neurobiological literature on aphasia recovery, the role of the right hemisphere in aphasia recovery remains unclear. Additional research is needed to understand biological mechanisms of recovery, in order to optimize brain stimulation treatments for aphasia. This article summarizes the current evidence on noninvasive brain stimulation methods for aphasia and the neuroscientific considerations surrounding treatments using right hemisphere inhibition. Suggestions are provided for further investigation and for clinicians whose patients ask about brain stimulation treatments for aphasia.

    We developed and explored the feasibility and user acceptance of the Cognitive Assessment for Aphasia App: a non-immersive virtual reality cognitive assessment for stroke survivors, designed to be inclusive of individuals with aphasia. Participants were assessed on a battery of pen-and-paper cognitive tests and the Cognitive Assessment for Aphasia App. Feasibility was explored by quantifying missing data for test completion, determining user acceptance for the app by measuring participants' preferred testing method, enjoyment and perceived task difficulty and time-taken to complete the test. Sixty-four stroke participants (35 with aphasia, 29 without aphasia) and 32 controls were recruited. Only one participant with aphasia was unable to complete all the Cognitive Assessment for Aphasia App tasks, whereas 13 participants were unable to complete all pen-and-paper tasks. Only 14% of participants preferred the pen-and-paper tests, and preference did not significantly differ between groups. Ninety-five per cent of participants were neutral or enjoyed the app and 4% perceived it to be very difficult. Higher age was negatively associated with user acceptance measures. The study shows preliminary evidence for the Cognitive Assessment for Aphasia App to be a feasible cognitive assessment for stroke survivors with and without aphasia. The app is currently being validated in stroke. Implications for rehabilitation The Cognitive Assessment for Aphasia App is a feasible tool for assessing post-stroke cognition in acute, inpatient rehabilitation and community settings. In research trials examining cognition, individuals with aphasia are often excluded. The Cognitive Assessment for Aphasia App permits the inclusion of these individuals, enhancing generalizability. The Cognitive Assessment for Aphasia App provides an alternative method to assess cognition that is quicker and preferred over standard neuropsychological tests.

    To determine factors that contribute to living well with aphasia in the first 12 months poststroke. Prospective longitudinal cohort study. Hospitalized care, ambulatory care, and general community. A referred sample of people (N=58) with a first incidence of aphasia after stroke was assessed at 3, 6, 9, and 12 months postonset. Participants were recruited through speech-language pathologists in 2 capital cities in Australia. Presence of aphasia was determined through the Western Aphasia Battery-Revised by an experienced speech-language pathologist. Not applicable. The main outcomes were the 5 domains of the Assessment for Living with Aphasia at 3, 6, 9, and 12 months poststroke. The independent variables included demographics, physical functioning, social network, mood, aphasia severity, and a self-rating of successfully living with aphasia at the same time points. Mixed effects modeling was used to determine which factors contributed to the trajectory of each of the 5 domains of participation, impairment, environment, personal factors, and life with aphasia. Higher household income, larger social network size, being a woman, and having milder aphasia were positively associated with the participation domain. Graduate or postgraduate educational levels, low mood, and poor physical functioning were negatively associated with the participation domain. Factors positively associated with other domains included higher income, self-ratings of successfully living with aphasia, and aphasia severity. Low mood was consistently negatively associated with all of the domains. Psychosocial determinants were the most significant predictors of living well with aphasia in the first 12 months postonset. Aphasia rehabilitation needs to attend more to these factors to optimize outcomes. Copyright © 2016 American Congress of Rehabilitation Medicine. Published by Elsevier Inc. All rights reserved.

    Individuals with primary progressive aphasia (PPA) show selective breakdown in regions within the proposed dorsal (articulatory-phonological) and ventral (lexical-semantic) pathways involved in language processing. Phonological short-term memory impairment, which has been attributed to selective damage to dorsal pathway structures, is considered to be a distinctive feature of the logopenic variant of PPA. By contrast, phonological abilities are considered to be relatively spared in the semantic variant and are largely unexplored in the nonfluent/agrammatic variant. Comprehensive assessment of phonological ability in the three variants of PPA has not been undertaken. We investigated phonological processing skills in a group of participants with PPA as well as healthy controls, with the goal of identifying whether patterns of performance support the dorsal versus ventral functional-anatomical framework and to discern whether phonological ability differs amongst PPA subtypes. We also explored the neural bases of phonological performance using voxel-based morphometry (VBM). Phonological performance was impaired in patients with damage to dorsal pathway structures (nonfluent/agrammatic and logopenic variants), with logopenic participants demonstrating particular difficulty on tasks involving nonwords. Binary logistic regression revealed that select phonological tasks predicted diagnostic group membership in the less fluent variants of PPA with a high degree of accuracy, particularly in conjunction with a motor speech measure. Brain-behavior correlations indicated a significant association between the integrity of gray matter in frontal and temporoparietal regions of the left hemisphere and phonological skill. Findings confirm the critical role of dorsal stream structures in phonological processing and demonstrate unique patterns of impaired phonological processing in logopenic and nonfluent/agrammatic variants of PPA.

    Objective To provide a quantitative algorithm for classifying primary progressive aphasia (PPA) into agrammatic (PPA-G), semantic (PPA-S) and logopenic (PPA-L) variants, each of which is known to have a different probability of association with Alzheimer’s disease (AD) versus frontotemporal lobar degeneration (FTLD). Design Prospectively and consecutively enrolled 16 PPA patients tested with neuropsychological instruments and magnetic resonance imaging (MRI). Setting University medical center. Participants PPA patients recruited nationally in the USA as part of a longitudinal study. Results A two-dimensional template, reflecting performance on tests of syntax (Northwestern Anagram Test) and lexical semantics (Peabody Picture Vocabulary Test), classified all 16 patients in concordance with a clinical diagnosis that had been made prior to the administration of the quantitative tests. All three subtypes had distinctly asymmetrical atrophy of the left perisylvian language network. Each subtype also had distinctive peak atrophy sites. Only PPA-G had peak atrophy in the IFG (Broca’s area), only PPA-S had peak atrophy in the anterior temporal lobe, and only PPA-L had peak atrophy in area 37. Conclusions Once an accurate root diagnosis of PPA is made, subtyping can be quantitatively guided using a two-dimensional template based on orthogonal tasks of grammatical competence and word comprehension. Although the choice of tasks and precise cut-off levels may evolve in time, this set of 16 patients demonstrates the feasibility of using a simple algorithm for clinico-anatomical classification in PPA. Prospective studies will show whether this suptyping can improve the clinical prediction of underlying neuropathology. PMID:20008661

To provide a quantitative algorithm for classifying PPA into agrammatic (PPA-G), semantic (PPA-S), and logopenic (PPA-L) variants, each of which is known to have a different probability of association with Alzheimer disease vs frontotemporal lobar degeneration. Prospective study. University medical center. Sixteen consecutively enrolled patients with PPA who underwent neuropsychological testing and magnetic resonance imaging recruited nationally in the United States as part of a longitudinal study. A 2-dimensional template that reflects performance on tests of syntax (Northwestern Anagram Test) and lexical semantics (Peabody Picture Vocabulary Test-Fourth Edition) classified all 16 patients in concordance with a clinical diagnosis that had been made before the administration of quantitative tests. All 3 PPA subtypes had distinctly asymmetrical atrophy of the left perisylvian language network. Each subtype also had distinctive peak atrophy sites: PPA-G in the inferior frontal gyrus (Broca area), PPA-S in the anterior temporal lobe, and PPA-L in Brodmann area 37. Once an accurate root diagnosis of PPA is made, subtyping can be quantitatively guided using a 2-dimensional template based on orthogonal tasks of grammatical competence and word comprehension. Although the choice of tasks and the precise cutoff levels may need to be adjusted to fit linguistic and educational backgrounds, these 16 patients demonstrate the feasibility of using a simple algorithm for clinicoanatomical classification in PPA. Prospective studies will show whether this subtyping can improve clinical prediction of the underlying neuropathologic condition.

  18. Aphasia treatment: intensity, dose parameters, and script training.

    PubMed

    Cherney, Leora R

    2012-10-01

    Studies of aphasia treatment have shown that intensive speech-language therapy is associated with significant improvements. However, there is no standard definition of intensity and the simplistic notion that "more is better" is not necessarily supported by the research. First, current evidence regarding intensity and aphasia treatment was briefly summarized. Second, studies that directly compare conditions of higher- and lower-intensity treatment for aphasia were reviewed with regard to the inclusion of parameters that contribute to a definition of intensity. In addition to five parameters proposed by Warren, Fey, and Yoder (2007) and highlighted by Baker (2012) , total number of sessions was also often documented. The review illustrated the complexity of quantifying the dose of comprehensive treatments that target multiple modalities and utilize a variety of different strategies. Third, data from a study reporting a relationship between intensive computer-based script training and outcomes in aphasia were examined. Results serve to illustrate Baker's contention that intensity alone is insufficient without also considering the active ingredients of the teaching episode. Information about dose, therapeutic inputs, and client acts can lead to better optimization of an intervention.

    2010-01-01

    Repetitive transcranial magnetic stimulation (rTMS) has been used to improve language behavior, including naming, in stroke patients with chronic, nonfluent aphasia. Part 1 of this paper reviews functional imaging studies related to language recovery in aphasia. Part 2 reviews the rationale for using rTMS to treat nonfluent aphasia (based on functional imaging); and presents our current rTMS protocol. We present language results from our rTMS studies, and imaging results from overt naming fMRI scans obtained pre- and post- a series of rTMS treatments. Part 3 presents results from a pilot study where rTMS treatments were followed immediately by constraint-induced language therapy. Part 4 reviews our diffusion tensor imaging study that examined possible connectivity of arcuate fasciculus to different parts of Broca’s area (pars triangularis, PTr; pars opercularis, POp); and to ventral premotor cortex (vPMC). The potential role of mirror neurons in R POp and vPMC in aphasia recovery is discussed. PMID:19818232

    Sequelae after a stroke are common and may lead to disability. Aphasia - defined as an acquired language disturbance - can cause important limitations in quality of life. To describe the epidemiological features of patients who had an aphasia after a first episode of ischemic stroke and their functional outcome at six months. Review of a database of a population study on the incidence, 30-day case fatality rate, and prognosis of stroke performed in a northern Chilean city between 2000 and 2002. Aphasia was diagnosed in 28 of 142 patients in whom the disorder was sought (20%). The projected incidence rate in the city where the study was carried out is 7.06 per 100,000 inhabitants. The mean age of these 28 patients was 66 ± 20 years and 53% were women. The main risk factor for stroke was hypertension in 62%. The etiology of stroke was undetermined in 64% of these patients. Partial anterior circulation infarction was the most common stroke location in 61%. Twenty percent of patients with a first episode of ischemic stroke have aphasia.

  2. [The origins of language: an analysis from the aphasia perspective].

    PubMed

    Ardila, A

    Different areas of knowledge have contributed to a better understanding of the origins of human language. AIM. To relate our current knowledge about the origins of language with the language pathology found in the case of brain injuries (aphasia). There are two fundamental forms of aphasia, which linked to defects in the lexico-semantic and grammatical systems of language (Wernicke-type aphasia and Broca-type aphasia, respectively). From observations made on children's development of language and experiments with primates, it has been shown that language initially appears as a lexico-semantic system. Grammar correlates with the ability to represent actions (verbs) and depends on what is known as Broca's area and its related brain circuits, but it is also related to the ability to quickly carry out the sequencing of the articulatory movements required for speaking (speech praxis). Language may have appeared as a lexico-semantic system much earlier than language as a syntactic system. The former may have developed around 200,000-300,000 years ago, coinciding with the increase in the temporal lobe, and would have existed in other hominids. Language as a grammatical system appeared perhaps as recently as 50,000 years ago and seems to be exclusive to Homo sapiens.

  11. Performance Variability as a Predictor of Response to Aphasia Treatment.

    PubMed

    Duncan, E Susan; Schmah, Tanya; Small, Steven L

    2016-10-01

    Performance variability in individuals with aphasia is typically regarded as a nuisance factor complicating assessment and treatment. We present the alternative hypothesis that intraindividual variability represents a fundamental characteristic of an individual's functioning and an important biomarker for therapeutic selection and prognosis. A total of 19 individuals with chronic aphasia participated in a 6-week trial of imitation-based speech therapy. We assessed improvement both on overall language functioning and repetition ability. Furthermore, we determined which pretreatment variables best predicted improvement on the repetition test. Significant gains were made on the Western Aphasia Battery-Revised (WAB) Aphasia Quotient, Cortical Quotient, and 2 subtests as well as on a separate repetition test. Using stepwise regression, we found that pretreatment intraindividual variability was the only predictor of improvement in performance on the repetition test, with greater pretreatment variability predicting greater improvement. Furthermore, the degree of reduction in this variability over the course of treatment was positively correlated with the degree of improvement. Intraindividual variability may be indicative of potential for improvement on a given task, with more uniform performance suggesting functioning at or near peak potential. © The Author(s) 2016.

    Individuals with agrammatic Broca's aphasia experience difficulty when processing reversible non-canonical sentences. Different accounts have been proposed to explain this phenomenon. The Trace Deletion account (Grodzinsky, 1995, 2000, 2006) attributes this deficit to an impairment in syntactic representations, whereas others (e.g., Caplan,…

  20. Non-verbal communication in severe aphasia: influence of aphasia, apraxia, or semantic processing?

    Patients suffering from severe aphasia have to rely on non-verbal means of communication to convey a message. However, to date it is not clear which patients are able to do so. Clinical experience indicates that some patients use non-verbal communication strategies like gesturing very efficiently whereas others fail to transmit semantic content by non-verbal means. Concerns have been expressed that limb apraxia would affect the production of communicative gestures. Research investigating if and how apraxia influences the production of communicative gestures, led to contradictory outcomes. The purpose of this study was to investigate the impact of limb apraxia on spontaneous gesturing. Further, linguistic and non-verbal semantic processing abilities were explored as potential factors that might influence non-verbal expression in aphasic patients. Twenty-four aphasic patients with highly limited verbal output were asked to retell short video-clips. The narrations were videotaped. Gestural communication was analyzed in two ways. In the first part of the study, we used a form-based approach. Physiological and kinetic aspects of hand movements were transcribed with a notation system for sign languages. We determined the formal diversity of the hand gestures as an indicator of potential richness of the transmitted information. In the second part of the study, comprehensibility of the patients' gestural communication was evaluated by naive raters. The raters were familiarized with the model video-clips and shown the recordings of the patients' retelling without sound. They were asked to indicate, for each narration, which story was being told and which aspects of the stories they recognized. The results indicate that non-verbal faculties are the most important prerequisites for the production of hand gestures. Whereas results on standardized aphasia testing did not correlate with any gestural indices, non-verbal semantic processing abilities predicted the formal diversity

    Background Constraint-induced aphasia therapy (CIAT) has been widely used in post-stroke aphasia rehabilitation. An increasing number of clinical controlled trials have investigated the efficacy of the CIAT for the post-stroke aphasia. Purpose To systematically review the randomized controlled trials (RCTs) concerning the effect of the CIAT in post-stroke patients with aphasia, and to identify the useful components of CIAT in post-stroke aphasia rehabilitation. Methods A computerized database search was performed through five databases (Pubmed, EMbase, Medline, ScienceDirect and Cochrane library). Cochrane handbook domains were used to evaluate the methodological quality of the included RCTs. Results Eight RCTs qualified in the inclusion criteria. Inconsistent results were found in comparing the CIAT with conventional therapies without any component from the CIAT based on the results of three RCTs. Five RCTs showed that the CIAT performed equally well as other intensive aphasia therapies, in terms of improving language performance. One RCT showed that therapies embedded with social interaction were likely to enhance the efficacy of the CIAT. Conclusion CIAT may be useful for improving chronic post-stroke aphasia, however, limited evidence to support its superiority to other aphasia therapies. Massed practice is likely to be a useful component of CIAT, while the role of “constraint” is needed to be further explored. CIAT embedded with social interaction may gain more benefits.

    Public awareness of aphasia has been surveyed in a number of countries revealing that it is universally low. We report results of surveys in the Balkan countries Serbia and Montenegro and compare results with data from Croatia and Slovenia. Convenience surveys of the general public were conducted in public places like shopping centers/malls and parks in Serbia (N = 400) and Montenegro (N = 500) using an adapted version of the public awareness of aphasia survey questionnaire. Respondents were asked whether they have heard of aphasia and tested with questions about aphasia. Information on gender, age, occupation and education was recorded. Twelve percent (Serbia) and 11% (Montenegro) had heard of aphasia, but just 4% (Serbia) and 3.2% (Montenegro) had a basic knowledge of aphasia. Age, gender and occupation interacted variably with awareness. Between 16% (Slovenia) and 60% (Croatia) said they had heard of aphasia (10.5% overall mean for the four countries) and basic knowledge of aphasia across the four countries ranged between 3.2 and 7%. Levels of awareness of aphasia in the Balkans are low and variably associated with age, gender, socio-economic and educational levels. Respondents with some knowledge of aphasia gained it through personal or professional interaction with aphasia or the media. The data provide a basis for awareness raising in Balkan countries to reduce stigmatization, improve community access and understanding. Implications for rehabilitation Awareness of aphasia is low universally, even among healthcare workers. Low public awareness of a condition, like aphasia, results in under-funded research and service provision. In order to raise public awareness of aphasia we need to know how many members of the general public know about it. Improvements in public awareness could positively affect funding, the quality of services, and the public understanding and acceptance of individuals with aphasia in the community.

    The application of transcranial direct current stimulation (tDCS) in chronic post stroke aphasia is documented in a substantial literature, and there is some new evidence that tDCS can augment favorable language outcomes in primary progressive aphasia. Anodal tDCS is most often applied to the left hemisphere language areas to increase cortical excitability (increase the threshold of activation) and cathodal tDCS is most often applied to the right hemisphere homotopic areas to inhibit over activation in contralesional right homologues of language areas. Outcomes usually are based on neuropsychological and language test performance, following a medical model which emphasizes impairment of function, rather than a model which emphasizes functional communication. In this paper, we review current literature of tDCS as it is being used as a research tool, and discuss future implementation of tDCS as an adjuvant treatment to behavioral speech-language pathology intervention. We review literature describing non-invasive brain stimulation, the mechanism of tDCS, and studies of tDCS in aphasia and neurodegenerative disorders. We discuss future clinical applications. tDCS is a promising adjunct to traditional speech-language pathology intervention to address speech-language deficits after stroke and in the neurodegenerative disease, primary progressive aphasia. Limited data are available regarding how performance on these types of specific tasks translates to functional communication outcomes.

    Changes in ERP (P100 and N400) and root mean square (RMS) were obtained during a silent reading task in 28 patients with chronic post-stroke aphasia in a randomized, double-blind, placebo-controlled trial of both memantine and constraint-induced aphasia therapy (CIAT). Participants received memantine/placebo alone (weeks 0-16), followed by drug treatment combined with CIAT (weeks 16-18), and then memantine/placebo alone (weeks 18-20). ERP/RMS values (week 16) decreased more in the memantine group than in the placebo group. During CIAT application (weeks 16-18), improvements in aphasia severity and ERP/RMS values were amplified by memantine and changes remained stable thereafter (weeks 18-20). Changes in ERP/RMS occurred in left and right hemispheres and correlated with gains in language performance. No changes in ERP/RMS were found in a healthy group in two separated evaluations. Our results show that aphasia recovery induced by both memantine alone and in combination with CIAT is indexed by bilateral cortical potentials.

    The clinical picture of acustico-mnestical aphasia, besides defects of understanding, naming and reiteration is characterized by disorders of a grammatical shaping of statements as well. Such disorders as yet have not been specially studied. The conducted study explored disorders and rehabilitation of speech grammar in 10 patients with acustico-mnestical aphasia with the aid of a neuro-linguistical analysis of spontaneous speech in patients and some special tests. The study made it possible to eliminate general types of agrammatism in different forms of aphasia and disorders, specific of acustico-mnestical aphasia. The suggested methods appeared to be adequate for a rehabilitation of speech grammar in this group of patients. Besides rehabilitative training may be used as a supplementary method for studying the character and structure of agrammatism in acustico-mnestical aphasia. The achieved results may be used for the diagnostics and rehabilitation of speech in this form of aphasia.

    Background Few studies have documented the possibility of treatment-induced improvements in language functions 12 months or longer after stroke. The purpose of the current study was to provide a preliminary estimate of efficacy of constraint-induced aphasia therapy (CIAT) when compared to no-intervention in patients with chronic (>1 year) post-stroke aphasia in order to provide the data needed to design an appropriately powered trial. Material/Methods This was a randomized, controlled, single-blinded, pilot trial. We identified 32 patients with chronic post-stroke aphasia. Of these, 27 were offered participation, and 24 were randomized (CONSORT diagram): 14 to CIAT and to 10 to no-intervention. CIAT groups received up to 4 hours/day of intervention for 10 consecutive business days (40 hours of therapy). Outcomes were assessed within 1 week of intervention and at 1 and 12 weeks after intervention and included several linguistic measures and a measure of overall subjective communication abilities (mini-Communicative Abilities Log (mini-CAL)). To maintain blinding, clinicians treating patients (CIAT group) did not communicate with other team members and the testing team members were blinded to treatment group assignment. Results Overall, the results of this pilot trial support the results of previous observational studies that CIAT may lead to improvements in linguistic abilities. At 12 weeks, the treatment group reported better subjective communication abilities (mini-CAL) than the no-intervention group (p=0.019). Other measures trended towards better performance in the CIAT group. Conclusions In this randomized, controlled, and blinded pilot study, intensive language therapy (CIAT) led to an improvement in subjective language abilities. The effects demonstrated allow the design of a definitive trial of CIAT in patients with a variety of post-stroke aphasia types. In addition, our experiences have identified important considerations for designing subsequent trial

    Loss of friendship post-onset of aphasia is well documented, with reduced social network size and social isolation commonly reported. Because friendship has strong links to psychological well-being and health, increased knowledge about friendships of individuals with aphasia will have important clinical implications. This study aimed to explore the perspectives of 25 community dwelling individuals with chronic aphasia on the role of friendship in living successfully with aphasia. Thematic analysis of transcripts from semi-structured in-depth interviews revealed three over-arching themes relating to the role of friendship in participants' experience of life with aphasia: living with changes in friendships, good times together and support from friends, and the importance of stroke and aphasia friends. Overall, findings highlighted the valued role of friendship in living successfully with aphasia, while also providing evidence of how friendships change and evolve in both negative and positive ways following onset of aphasia. Clinicians are challenged to work creatively to address the role of friendship in life post-stroke in partnership with individuals with aphasia, their families, and friends.

    Despite being perhaps the most studied form of aphasia, the critical lesion location for Broca's aphasia has long been debated, and in chronic patients, cortical damage often extends far beyond Broca's area. In a group of 70 patients, we examined brain damage associated with Broca's aphasia using voxel-wise lesion-symptom mapping (VLSM). We found that damage to the posterior portion of Broca's area, the pars opercularis, is associated with Broca's aphasia. However, several individuals with other aphasic patterns had considerable damage to pars opercularis, suggesting that involvement of this region is not sufficient to cause Broca's aphasia. When examining only individuals with pars opercularis damage, we found that patients with Broca's aphasia had greater damage in the left superior temporal gyrus (STG; roughly Wernicke's area) than those with other aphasia types. Using discriminant function analysis and logistic regression, based on proportional damage to the pars opercularis and Wernicke's area, to predict whether individuals had Broca's or another types of aphasia, over 95% were classified correctly. Our findings suggest that persons with Broca's aphasia have damage to both Broca's and Wernicke's areas, a conclusion that is incongruent with classical neuropsychology, which has rarely considered the effects of damage to both areas.

    To evaluate the psychometric properties of the Italian version of Functional Outcome Questionnaire - Aphasia. Two hundred and five persons with stroke-related aphasia and right hemiparesis who received ongoing assistance from a family caregiver were assessed using the Functional Outcome Questionnaire - Aphasia, Aachener Aphasie Test, Token Test, Raven's Coloured Progressive Matrices, Functional Independence Measure (FIM), Functional Assessment Measure (FAM), and Quality of Life Questionnaire for Aphasics (QLQA). The Functional Outcome Questionnaire - Aphasia was translated into the Italian language using a translation and back-translation method. Reliability and construct validity of the Functional Outcome Questionnaire - Aphasia were evaluated. The Italian version of the Functional Outcome Questionnaire - Aphasia showed good internal consistency and test-retest reliability for the overall scale (α = 0.98; ICC = 0.95) and subscales (α = 0.89 for the communicating basic needs (CBN), α = 0.92 for the making routine requests (MRR), α = 0.96 for the communicating new information (CNI), α = 0.93 for the attention/other communication skills (AO); ICC = 0.95 for CBN, ICC = 0.96 for MRR, ICC = 0.97 for CNI and ICC = 0.92 for AO). Significant correlations were found between the Functional Outcome Questionnaire - Aphasia and Token Test, QLQA, Aachener Aphasie Test scores, and FAM linguistic scores, indicating good convergent validity. Low correlations were found between Functional Outcome Questionnaire - Aphasia and Raven's Coloured Progressive Matrices and FIM motor scores, showing good discriminant validity. The overall findings of this study supported the reliability and construct validity of the Italian version of the Functional Outcome Questionnaire - Aphasia. This measure holds considerable promise in assessing the functional outcomes of aphasia rehabilitation in Italian-speaking persons with aphasia. Implications for

    This study investigated how patients with severe aphasia communicated in daily living, which verbal and non-verbal communication skills were spared and which were impaired, and whether activity limitations in communication are related to verbal impairments. Twenty-seven patients with severe aphasia and 9 with moderate aphasia originating from a sample of 102 aphasic persons followed up in a French regional survey were assessed with a communication test and a communication activity limitation questionnaire 12-18 months after a first stroke. Patients with severe aphasia suffered severe activity limitations in communication, with performance 3-fold lower than that of patients with moderate aphasia, and 4-fold lower than scores attained by normals. Both aphasia severity and communication disability at follow-up were related to the initial severity of aphasia. Using a phone, credit card and a chequebook, reading and filling in administrative documents, and communication behaviours involved in social life were the most severely impaired. Non-verbal communication performance was not related to aphasia severity. We conclude that there is a great need for speech therapy research to develop new compensatory or alternative strategies for patients with severe aphasia.

    Coverbal gesture use, which is affected by the presence and degree of aphasia, can be culturally specific. The purpose of this study was to compare gesture use among Cantonese-speaking individuals: 23 neurologically healthy speakers, 23 speakers with fluent aphasia, and 21 speakers with nonfluent aphasia. Multimedia data of discourse samples from these speakers were extracted from the Cantonese AphasiaBank. Gestures were independently annotated on their forms and functions to determine how gesturing rate and distribution of gestures differed across speaker groups. A multiple regression was conducted to determine the most predictive variable(s) for gesture-to-word ratio. Although speakers with nonfluent aphasia gestured most frequently, the rate of gesture use in counterparts with fluent aphasia did not differ significantly from controls. Different patterns of gesture functions in the 3 speaker groups revealed that gesture plays a minor role in lexical retrieval whereas its role in enhancing communication dominates among the speakers with aphasia. The percentages of complete sentences and dysfluency strongly predicted the gesturing rate in aphasia. The current results supported the sketch model of language-gesture association. The relationship between gesture production and linguistic abilities and clinical implications for gesture-based language intervention for speakers with aphasia are also discussed.

    We have developed a Japanese version of the Stroke and Aphasia Quality of Life Scale-39 (SAQOL-39), designated as SAQOL-39-J, and used psychometric methods to examine its acceptability and reliability. The acceptability and reliability of SAQOL-39-J, which was developed from the English version using a standard translation and back-translation method, were examined in 54 aphasia patients using standard psychometric methods. The acceptability and reliability of SAQOL-39-J were then compared among patients with different types of aphasia. SAQOL-39-J showed good acceptability, internal consistency (Cronbach's α score = .90), and test-retest reliability (intraclass correlation coefficient = .97). Broca's aphasia patients showed the lowest total scores and communication scores on SAQOL-39-J. The Japanese version of SAQOL-39, SAQOL-39-J, provides acceptable and reliable data in Japanese stroke patients with aphasia. Among different types of aphasia, Broca's aphasia patients had the lowest total and communication SAQOL-39-J scores. Further studies are needed to assess the effectiveness of health care interventions on health-related quality of life in this population. Copyright © 2015 National Stroke Association.

    The concept of living successfully with aphasia has recently emerged as an alternative to more traditional "deficit" models in aphasiology, encouraging a focus on positive rather than negative outcomes. This research aimed to integrate findings from studies exploring the perspectives of three participant groups (individuals with aphasia, speech-language pathologists, and family members) about living successfully with aphasia. Qualitative meta-analysis of three studies conducted by the authors was used to integrate perspectives across the participant groups. Steps in the qualitative meta-analysis were based on those described in the process of "meta-ethnography" by Noblit and Hare (1988) . Analysis was an inductive process, in which data from each study were re-analysed and translated into each other in order to identify higher-level overarching themes that accounted for similarities and discrepancies across the original studies. A total of seven overarching themes related to living successfully with aphasia were identified. These were: participation, meaningful relationships, support, communication, positivity, independence and autonomy, and living successfully with aphasia as a journey over time. Findings indicate the need for a holistic, client-centred approach that considers communication in the broader context of an individual's daily life. The overarching themes may act as guides for areas of importance to be addressed in clinical practice, as well as in future research. By working in partnership with individuals with aphasia and their families, speech-language pathologists are challenged to continue to improve services and assist clients on their journey of living successfully with aphasia.

    To explore the evidence on rehabilitation of stroke patients with aphasia in relation to nursing care, focusing on the following themes: (1) the identification of aphasia, (2) the effectiveness of speech-language interventions. Patients with poststroke aphasia have higher mortality rates and worse functional outcome than patients without aphasia. Nurses are well aware of aphasia and the associated problems for patients with stroke because they have daily contact with them. The challenge is to provide evidence-based care directed at the aphasia. Although rehabilitation stroke guidelines are available, they do not address the caregiving of nurses to patients with aphasia. Systematic review. Published studies were reviewed, focusing on identification and treatment of aphasic patients after stroke in terms of the consequences for nursing care. Also, data concerning effective speech-language interventions were extrapolated into nursing practice with respect to the classification of nursing interventions. Intensive speech-language therapy, which was initiated in the acute stage post stroke, showed the best rehabilitation outcomes. Trained persons other than speech-language therapists provided effective speech-language interventions. Speech-language therapy included several types of intervention that met nursing intervention classifications. The contribution of nursing to the rehabilitation of patients with aphasia is relevant. The use of screening instruments by nurses can increase early detection of aphasia, a precondition for initiating timely speech-language therapy. Collaboration between speech-language therapists and nurses is of the utmost importance for increasing the intensity and functionality of speech-language exercises, which may enhance the quality of treatment. The findings of this study can be used to develop nursing rehabilitation guidelines for stroke patients with aphasia. Further research is necessary to explore the feasibility of using such guidelines

    Frontotemporal dementias are neurodegenerative diseases in which symptoms of frontal and/or temporal lobe disease are the first signs of the illness, and as the diseases progress, they resemble a focal left hemisphere process such as stroke or traumatic brain injury, even more than a neurodegenerative disease. Over time, some patients develop a more generalized dementia. Four clinical subtypes characterize the predominant presentations of this illness: behavioral or frontal variant FTD, progressive nonfluent aphasia, semantic dementia, and logopenic primary progressive aphasia. These clinical variants correlate with regional patterns of atrophy on brain imaging studies such as MRI and PET scanning, as well as with biochemical and molecular genetic variants of the disorder. The treatment is as yet only symptomatic, but advances in molecular genetics promise new therapies. PMID:24966676

    Evidence suggests that persons with aphasia (PWAs) present with working memory impairments that affect a variety of language tasks. Most of these studies have focused on the phonological loop component of working memory and little attention has been paid to the episodic buffer component. The episodic buffer, as a limited capacity, multimodal system that binds and integrates information from the phonological loop, visuospatial sketchpad, and long-term memory would likely be involved in discourse processing. The purposes of this article were to (1) review discourse level deficits associated with aphasia, (2) describe how a deficit at the level of the episodic buffer could cause such deficits, (3) to review discourse treatment approaches for PWAs, and (4) present preliminary results from a novel discourse treatment study for PWAs.

    We described a 56-years-old man with a diagnosis of "non-fluent primary progressive aphasia" (NfPPA). An accurate neuropsychological, neurological and neuroimaging evaluation was performed in order to assess clinical and behavioural features of the patient. From a neuropsychological point of view, the patient showed a typical cognitive profile of subjects affected by NfPPA: a prominent language deficit, associated with impairments in several cognitive domains after three years from the onset of the symptomatology. The most intriguing feature is that SPECT revealed hypoperfusion in the right frontal cortex, albeit the patient is right-handed. This unexpected finding shows that NfPPA may arise not only from cortical abnormalities in the language-dominant left hemisphere, but also from right hemisphere involvement in a right hander (crossed aphasia).

    The aim of this study was to investigate the time window, duration and intensity of optimal speech and language therapy applied to aphasic patients with subacute stroke in our hospital. The study consisted of 33 patients being hospitalized for stroke rehabilitation in our hospital with first stroke but without previous history of speech and language therapy. Sixteen sessions of impairment-based speech and language therapy were applied to the patients, 30–60 minutes per day, 2 days a week, for 8 successive weeks. Aphasia assessment in stroke patients was performed with Gülhane Aphasia Test-2 before and after treatment. Compared with before treatment, fluency of speech, listening comprehension, reading comprehension, oral motor evaluation, automatic speech, repetition and naming were improved after treatment. This suggests that 16 seesions of speech and language therapy, 30–60 minutes per day, 2 days a week, for 8 successive weeks, are effective in the treatment of aphasic patients with subacute stroke.

    A theoretical framework which considers the verbal functions of the brain under a multivariate and comprehensive cognitive model was statistically analyzed. A confirmatory factor analysis was performed to verify whether some recognized aphasia constructs can be hierarchically integrated as latent factors from a homogenously verbal test. The Brief Aphasia Evaluation was used. A sample of 65 patients with left cerebral lesions, and two supplementary samples comprising 35 patients with right cerebral lesions and 30 healthy participants were studied. A model encompassing an all inclusive verbal organizer and two successive organizers was validated. The two last organizers were: three factors of comprehension, expression and a "complementary" verbal factor which included praxia, attention, and memory; followed by the individual (and correlated) factors of auditory comprehension, repetition, naming, speech, reading, writing, and the "complementary" factor. By following this approach all the patients fall inside the classification system; consequently, theoretical improvement is guaranteed.

    Based on an aphasia test for Spanish speakers which analyze the patient's basic resources of verbal communication, a web-enabled software was developed to automate its execution. A clinical database was designed as a complement, in order to evaluate the antecedents (risk factors, pharmacological and medical backgrounds, neurological or psychiatric symptoms, brain injury -anatomical and physiological characteristics, etc) which are necessary to carry out a multi-factor statistical analysis in different samples of patients. The automated test was developed following service oriented architecture and implemented in a web site which contains a tests suite, which would allow both integrating the aphasia test with other neuropsychological instruments and increasing the available site information for scientific research. The test design, the database and the study of its psychometric properties (validity, reliability and objectivity) were made in conjunction with neuropsychological researchers, who participate actively in the software design, based on the patients or other subjects of investigation feedback.

    The Bilingual Aphasia Test (BAT) is designed to be objective (so it can be administered by a lay native speaker of the language) and equivalent across languages (to allow for a comparison between the languages of a given patient as well as across patients from different institutions). It has been used not only with aphasia but also with any condition that results in language impairment (Alzheimer's, autism, cerebellar lesions, developmental language disorders, mild cognitive impairment, motor neuron disease, multiple sclerosis, Parkinson's, vascular dementia, etc.). It has also been used for research purposes on non-brain-damaged unilingual and bilingual populations. By means of its 32 tasks, it assesses comprehension and production of implicit linguistic competence and metalinguistic knowledge (which provide indications for apposite rehabilitation strategies). Versions of the BAT are available for free download at www.mcgill.ca/linguistics/research/bat/.

    The medical profession and therapists continue to believe that total aphasia is untreable. A case report is used to demonstrate the diagnostic features of aphasia and describe the course of the impairment from the complete loss of speech, via the learning of highly automated expressions to the aquisition of single words which the patient uses independently in the different contexts. This development involves all language functions equally. The therapy is based on conventional methods, deblocking stategies, speech therapeutic talks - principal item of the treatment - and dialogue exercises carried out under normal conditions. The problems relating to deblocking methods are discussed. A description is made of the methods which have been developed from a combined audiovisual, tactile and writing motoric speech activation programme. The article presents the linguistic signs of the syndrome in an advanced stage and demonstrates the development of the thinking structure and the psychic problems with the help of the tree drawings.

    This paper argues that some of the patterns seen in aphasia may reflect difficulties in the cognitive preparations for language. In particular, some individuals might be unable to carry out processes of 'Thinking for Speaking' (Slobin 1996), which frame thoughts for language production. Evidence to support this proposal is presented, together with signs that such thinking can be assisted with cues and therapy. It is argued that these preliminary data need to be pursued via a more comprehensive investigation of thinking therapy.

    To update a previous systematic review describing the effect of communication partner training on individuals with aphasia and their communication partners, with clinical questions addressing effects of partner training on language, communication activity/participation, psychosocial adjustment, and quality of life. Twelve electronic databases were searched using 23 search terms. References from relevant articles were hand searched. Three reviewers independently reviewed abstracts, excluding those that failed to meet inclusion criteria. Thirty-two full text articles were reviewed by 2 independent reviewers. Articles not meeting inclusion criteria were eliminated, resulting in a corpus of 25 articles for full review. For the 25 articles, 1 reviewer extracted descriptive data regarding participants, intervention, outcome measures, and results. A second reviewer verified the accuracy of the extracted data. The 3-member review team classified studies using the American Academy of Neurology levels of evidence. Two independent reviewers evaluated each article using design-specific tools to assess research quality. All 25 of the current review articles reported positive changes from partner training. Therefore, to date, 56 studies across 2 systematic reviews have reported positive outcomes from communication partner training in aphasia. The results of the current review are consistent with the previous review and necessitate no change to the earlier recommendations, suggesting that communication partner training should be conducted to improve partner skill in facilitating the communication of people with chronic aphasia. Additional high-quality research is needed to strengthen the original 2010 recommendations and expand recommendations to individuals with acute aphasia. High-quality clinical trials are also needed to demonstrate implementation of communication partner training in complex environments (eg, health care). Copyright © 2016 American Congress of

    It is currently unknown how rehabilitation services contribute to significant others' adjustment to stroke with aphasia since their experience of rehabilitation has not been studied before. The purpose of this study was thus to understand significant others' experience of aphasia rehabilitation within the context of post-stroke rehabilitation. Individual interviews were carried out with 12 significant others of persons who became aphasic as a result of a stroke and were discharged from rehabilitation in the past 3 months. Data were analyzed with a grounded theory approach. "Being centered on the aphasic person" was the core category triggered by the significant other's perception of the stroke survivor's vulnerability and his/her feelings of attachment towards that person. Through their interactions with professionals, significant others assumed that rehabilitation was also centered on the aphasic person; a perspective that was reinforced. Consequently, significant others participated in rehabilitation as caregivers and expected rehabilitation to meet their caregiver needs but not other personal and relational needs. Their appraisal of rehabilitation was thus related to the satisfaction or not of caregiver needs. With a greater sensitivity to significant others who focus on the stroke survivor and disregard their own needs, rehabilitation professionals and especially speech-language therapists, can assist families in reestablishing communication and satisfying relationships which are affected because of aphasia. This qualitative study shows that significant others of aphasic stroke survivors experience rehabilitation as services focused on the person who had the stroke. Significant others' satisfaction with rehabilitation is not related to the fulfillment of their personal (e.g. resuming their activities) and relational needs (e.g. good communication with the person with aphasia). When offering interventions targeting significant others' needs, rehabilitation

    We report a patient with pure anomic aphasia following encephalitis. Brain magnetic resonance imaging (MRI) revealed bilateral temporal lesions, and subsequent focal atrophy in the left anterior inferior temporal lobe. Over the course of a 2-year follow-up, the patient's naming difficulty persisted without other dysfunction of language or memory. These observations indicate a contribution of the left anterior inferior temporal region to object naming.

    The objective of this study is to determine which cognitive processes underlying spelling are most affected in the three variants of primary progressive aphasia (PPA): Logopenic variant primary progressive aphasia (lvPPA), Semantic variant primary progressive aphasia (svPPA), and Nonfluent variant primary progressive aphasia (nfvPPA). 23 PPA patients were administered The Johns Hopkins Dysgraphia Battery to assess spelling. Subtests evaluate for effects of word frequency, concreteness, word length, grammatical word class, lexicality (words vs pseudowords), and "regularity" by controlling for the other variables. Significant effects of each variable were identified with chi square tests. Responses on all spelling to dictation tests were scored by error type. 16 of the 23 subjects also had a high resolution MRI brain scan to identify areas of atrophy. We identified 4 patterns of spelling that could be explained by damage to one or more cognitive processes underlying spelling. Nine patients (3 unclassifiable, 4 with lvPPA, 2 with svPPA) had dysgraphia explicable by impaired access to lexical representations, with reliance on sublexical phonology-to-orthography conversion (POC). Two patients (with nfvPPA) showed dysgraphia explicable by impaired access to lexical representations and complete disruption of sublexical POC. Seven patients (4 with lvPPA, 1 with svPPA, 2 unclassifiable) showed dysgraphia explicable by impaired access to lexical-semantic representations and/or lexical representations with partially spared sublexical POC mechanisms. Five patients (1 with nfvPPA, 2 with svPPA, 1 with lvPPA, and 1 unclassifiable) showed dysgraphia explicable by impairment of the graphemic buffer. Any cognitive process underlying spelling can be affected in PPA. Predominance of phonologically plausible errors, more accurate spelling of regular words than irregular words, and more accurate spelling of pseudowords than words (indicating spared POC mechanisms) may indicate a low

    Two patients with mixed transcortical aphasia could repeat propositional speech but not affective prosody. These findings suggest that the intact perisylvian region responsible for propositional speech does not mediate effective prosody. We propose that affective prosody is incorporated into propositional speech by means of an interhemispheric mechanism and that the failure of these patients to repeat affective prosody was caused by a disconnection of the left perisylvian structures from the right hemisphere structures thought to mediate affective prosody.

    Carl Wernicke (1848-1905) is traditionally considered the first to have described the features of, and the brain pathology underlying, impaired auditory comprehension and related symptoms. Although Wernicke (1874) clearly and repeatedly indicates his indebtedness to Theodor von Meynert (1833-1892), this is usually understood as an acknowledgment that Meynert taught Wernicke neuroanatomy (Eggert, 1977); Wernicke's own words in part support this interpretation. A more sophisticated historical analysis notes that, prior to Wernicke, both Johann Schmidt in 1871 and Charlton Bastian in 1869 had described the concept of receptive aphasia, but neither had supported their analyses with autopsy evidence as did Wernicke, thus not dislodging Wernicke's claim of priority. However, a virtually unknown work by Theodor von Meynert, published in 1866, has recently been rediscovered by us ["Ein Fall von Sprachstörung, anatomisch begründet." Medizinische Jahrbücher. XII Band der Zeitschrift der K. K. Gesellleschaft der Arzte in Wien, 22. Jahr. Pp. 152-189]. In this paper Meynert analyzes the anatomical basis for localizing the comprehension of language in the superior temporal gyrus, he argues that lesions in this area should (by analogy to Broca's earlier observations on language expression) cause impairments in language comprehension, and he presents a case of receptive aphasia with autopsy evidence of destruction of the superior temporal gyrus in the left hemisphere. The patient's aphasia was classic; impaired auditory comprehension, and fluent speech with paraphasias. It is clear that Meynert should be given historical credit for his work.

    We performed a comprehensive cognitive, neuroimaging, and genetic study of 31 patients with primary progressive aphasia (PPA), a decline in language functions that remains isolated for at least 2 years. Detailed speech and language evaluation was used to identify three different clinical variants: nonfluent progressive aphasia (NFPA; n = 11), semantic dementia (SD; n = 10), and a third variant termed logopenic progressive aphasia (LPA; n = 10). Voxel-based morphometry (VBM) on MRIs showed that, when all 31 PPA patients were analyzed together, the left perisylvian region and the anterior temporal lobes were atrophied. However, when each clinical variant was considered separately, distinctive patterns emerged: (1) NFPA, characterized by apraxia of speech and deficits in processing complex syntax, was associated with left inferior frontal and insular atrophy; (2) SD, characterized by fluent speech and semantic memory deficits, was associated with anterior temporal damage; and (3) LPA, characterized by slow speech and impaired syntactic comprehension and naming, showed atrophy in the left posterior temporal cortex and inferior parietal lobule. Apolipoprotein E ε4 haplotype frequency was 20% in NFPA, 0% in SD, and 67% in LPA. Cognitive, genetic, and anatomical features indicate that different PPA clinical variants may correspond to different underlying pathological processes. PMID:14991811

  17. Primary progressive aphasia: A dementia of the language network.

    PubMed

    Mesulam, Marsel

    2013-01-01

    Primary progressive aphasia (PPA) is a clinical syndrome diagnosed when three core criteria are met. First, there should be a language impairment (i.e., aphasia) that interferes with the usage or comprehension of words. Second, the neurological work-up should determine that the disease is neurodegenerative, and therefore progressive. Third, the aphasia should arise in relative isolation, without equivalent deficits of comportment or episodic memory. The language impairment can be fluent or non-fluent and may or may not interfere with word comprehension. Memory for recent events is preserved although memory scores obtained in verbally mediated tests may be abnormal. Minor changes in personality and behavior may be present but are not the leading factors that bring the patient to medical attention or that limit daily living activities. This distinctive clinical pattern is most conspicuous in the initial stages of the disease, and reflects a relatively selective atrophy of the language network, usually located in the left hemisphere. There are different clinical variants of PPA, each with a characteristic pattern of atrophy. The underlying neuropathological diseases are heterogeneous and can include Alzheimer's disease as well as frontotemporal lobar degeneration. The clinician's task is to recognize PPA and differentiate it from other neurodegenerative phenotypes, use biomarkers to surmise the nature of the underlying neuropathology, and institute the most fitting multimodal interventions.

    Background. Assessment of sentence-level auditory comprehension can be performed with a variety of tests varying in response requirements. A brief and easy to administer measure, not requiring an overt verbal or a complex motor response, is essential in any test battery for aphasia. Objective. The present study examines the clinical utility of receptive language indices for individuals with aphasia based on the Comprehension of Instructions in Greek (CIG), a variant of the Token Test, and the Greek version of PPVT-R. Methods. Normative data from a large community sample of Greek adults aged 46–80 years was available on both measures. A word-level-independent measure of auditory comprehension was computed as the standard score difference between the two tests and used to compare patients with and without comprehension deficits as indicated by their Boston Diagnostic Aphasia Examination profile. Results and Conclusions. Indices of internal consistency and test-retest reliability were very good. Education and age effects on performance were significant, with the former being stronger. The potential clinical utility of differential ability indices (contrasting sentence- and word-level auditory comprehension tests) is discussed. PMID:24825951

    Dr Christopher Green is a well-known paediatrician and parenting author, who appeared frequently on Australian radio and television and lectured in Australia and many countries around the world. In 1999, Dr Green had a stroke which left him with aphasia and ended his career. After the death of his wife in 2004, Dr Green used exercise and the goal of writing again to lift himself out of his grief. With the help of a gifted editor, he wrote a new edition of his best-selling book Toddler Taming (Green, 2006 ), and in the process recovered much of his language. Dr Green is the Patron of the Australian Aphasia Association, and has in recent years returned to public speaking. In this address, he shares his message that the language gains made with aphasia may occur over decades, not merely one or two years. This article is an edited version of the keynote speech Dr Green presented at the Speech Pathology Australia annual conference in 2007.

    Purpose The lateralization of cognitive functions in crossed aphasia in dextrals (CAD) has been explored and compared mainly with cases of aphasia with left hemisphere damage. However, comparing the neuropsychological aspects of CAD and aphasia after right brain damage in left-handers (ARL) could potentially provide more insights into the effect of a shift in the laterality of handedness or language on other cognitive organization. Thus, this case study compared two cases of CAD and one case of ARL. Materials and Methods The following neuropsychological measures were obtained from three aphasic patients with right brain damage (two cases of CAD and one case of ARL); language, oral and limb praxis, and nonverbal cognitive functions (visuospatial neglect and visuospatial construction). Results All three patients showed impaired visuoconstructional abilities, whereas each patient showed a different level of performances for oral and limb praxis, and visuospatial neglect. Conclusion Based on the analysis of these three aphasic patients' performances, we highlighted the lateralization of language, handedness, oral and limb praxis, visuospatial neglect and visuospatial constructive ability in aphasic patients with right brain damage.

    2004-08-01

    The evaluation of auditory-visual speech perception is not typically undertaken in the assessment of aphasia; however, treatment approaches utilise bimodal presentations. Research demonstrates that auditory and visual information are integrated for speech perception. The strongest evidence of this cross-modal integration is the McGurk effect. This indirect measure of integration shows that presentation of conflicting tokens may change perception (e.g. auditory /bi/ + visual /gi/ = /di/). The purpose of this study was to investigate the ability of a person with mild aphasia to identify tokens presented in auditory-only, visual-only and auditory-visual conditions. It was hypothesized that performance would be best in the bimodal condition and that presence of the McGurk effect would demonstrate integration of speech information. Findings did not support the hypotheses. It is suspected that successful integration of AV speech information was limited by a perseverative response pattern. This case study suggests the use of bisensory speech information may be impaired in adults with aphasia.

    DeDe, Gayle

    2012-01-01

    The purpose of this study was to determine whether and when individuals with aphasia and healthy controls use lexical and prosodic information during on-line sentence comprehension. Individuals with aphasia and controls (n = 12 per group) participated in a self-paced listening experiment. The stimuli were early closure sentences, such as “While the parents watched(,) the child sang a song.” Both lexical and prosodic cues were manipulated. The cues were biased toward the subject- or object- of the ambiguous noun phrase (the child). Thus, there were two congruous conditions (in which both lexical cues and prosodic cues were consistent) and two incongruous conditions (in which lexical and prosodic cues conflicted). The results showed that the people with aphasia had longer listening times for the ambiguous noun phrase (the child) when the cues were conflicting, rather than consistent. The controls showed effects earlier in the sentence, at the subordinate verb (watched or danced). Both groups showed evidence of reanalysis at the main verb (sang). These effects demonstrate that the aphasic group was sensitive to the lexical and prosodic cues, but used them on a delayed time course relative to the control group. PMID:22143353

    Primary progressive aphasia (PPA) is a group of disorders with progressive language impairment. Abnormal behaviour may develop in PPA as the disease evolves, but the clinical features and brain basis of behavioural change in PPA have not been fully defined. 33 PPA patients (9 semantic dementia, SD, 14 progressive nonfluent aphasia, PNFA, 7 logopenic/phonological aphasia, LPA and 3 patients with a PPA syndrome in association with progranulin mutations, GRN-PPA) were assessed using the Neuropsychiatric Inventory to record behavioural changes, as well as volumetric MR imaging. The most common abnormal behaviours in SD were irritability, disinhibition, depression and abnormal appetite, in PNFA apathy, agitation and depression, in LPA anxiety, irritability, agitation and apathy, and in GRN-PPA apathy and irritability. Voxel-based morphometry analysis revealed greater atrophy of right lateral orbitofrontal cortex (OFC) in PPA patients with anxiety, apathy, irritability/lability and abnormal appetite/eating disorders, and greater atrophy of left OFC in those with disinhibition. Areas involved beyond OFC included right dorsolateral prefrontal cortex (apathy), right cingulate (irritability/lability) and left anterior superior and medial temporal lobe (disinhibition). Behavioural abnormalities may be clinically significant in PPA, and these abnormalities are underpinned by atrophy of overlapping frontotemporal networks centred on OFC. PMID:20400120

    The use of mobile technology, including smartphones and tablet devices, is a growing trend among adults nationwide, and its potential use in aphasia rehabilitation has generated widespread interest. Despite this trend, adults living with disability are less likely than other adults to go online. Complicating things further, most adults living with aphasia come from a generation where computers and technology were not an integral part of their lives. Additionally, training adults with aphasia requires a different approach than training those in the same age bracket without a disability. This article describes the mobile technology program at the Adler Aphasia Center in Maywood, New Jersey. The goal of this program is to improve access to mobile technology for people with aphasia. The use of mobile devices is the focus of the article. Mobile technology concepts and skills needed to establish a strong foundation for successful iPad (Apple Inc., Cupertino, CA) use are suggested. We discuss how apps may be used to support aphasia therapy with a focus on apps that are native to the iPad and on other apps that were not specifically developed for aphasia rehabilitation. Challenges in implementing a mobile technology program for people with aphasia and individual member success stories are included.

    PubMed

    Bersano, A; Burgio, F; Gattinoni, M; Candelise, L

    2009-12-01

    The aim of our study is to evaluate the frequency of aphasia and to describe the characteristics of aphasics among a large sample of acute stroke patients in Italy. Out of the 11 572 stroke patients hospitalised within 48 h from stroke onset, included in the PROSIT study, we selected 9594 alert cases for the estimation of aphasia frequency. The presence of aphasia was accepted when registered in the clinical records at the first neurological examination. All patients/caregivers underwent to a 2-year telephone follow-up evaluation. Twenty-eight per cent of alert acute stroke patients had aphasia, which was associated with arm and/or limb weakness in 74% of cases. In our series, aphasia was more frequent in females than males, in patients older than 75 years and was associated with more severe stroke. Aphasics, compared with nonaphasics, died more frequently. Aphasia was also significantly associated with residual poststroke disability. This is the first study considering the frequency of aphasia in a wide population of hospitalised acute stroke patients. The presence of aphasia is more common in patients with severe stroke and contributes to residual disability. Our findings should be considered for setting early specific rehabilitation programmes.

  16. Interaction-focussed therapy for aphasia: Effects on communication and quality of life.

    PubMed

    Barnes, Scott; Nickels, Lyndsey

    2017-07-06

    This study examined the effects of an interaction-focussed therapy for aphasia, which involved both people with aphasia and their familiar conversation partners. It was hypothesised the interaction-focussed therapy would lead to positive changes in targeted conversation behaviours, and improved quality of life for participants with aphasia. Three people with chronic aphasia and three of their familiar conversation partners completed an 8-week interaction-focussed therapy programme. A series of single case multiple-baseline ABA experiments were conducted. Outcome measures focussed on changes in targeted behaviours between pre- and post-therapy conversation samples, and changes in quality of life. All participant dyads improved their conversations. Familiar conversation partners demonstrated significant changes in targeted behaviours, while only one participant with aphasia achieved significant improvements. There was little evidence of a positive impact on quality of life for participants with aphasia. Interaction-focussed therapy enhances everyday communication for people with aphasia and their conversation partners. However, the complex nature of learning in this intervention means that further, likely interdisciplinary work is required to better understand what mediates skill acquisition and therapeutic change and its psychosocial impact. This information is particularly important for optimising interaction-focussed therapy for people with aphasia.

    To provide a preliminary estimate of efficacy of constraint-induced aphasia therapy (CIAT) when compared to no-intervention in patients with chronic (>1 year) post-stroke aphasia in order to plan an appropriately powered randomized controlled trial (RCT). We conducted a pilot single-blinded RCT. 24 patients were randomized: 14 to CIAT and 10 to no-intervention. CIAT groups received up to 4 hours/day of intervention for 10 consecutive business days (40 hours or therapy). Outcomes were assessed within 1 week of intervention and at 1 and 12 weeks after intervention and included several linguistic measures and a measure of overall subjective communication abilities (mini-Communicative Abilities Log (mini-CAL)). Clinicians treating patients (CIAT group) did not communicate with other team members to maintain blinding and the testing team members were blinded to treatment group assignment. Overall, the results of this pilot RCT support the results of previous observational studies that CIAT may lead to improvements in linguistic abilities. At 12 weeks, the treatment group reported better subjective communication abilities (mini-CAL) than the no-intervention group (p=0.019). Other measures trended towards better performance in the CIAT group. In this pilot RCT intensive language therapy led to an improvement in subjective language abilities. The effects demonstrated allow the design of a definitive trial of CIAT in patients with a variety of post-stroke aphasia types. In addition, our experiences have identified important considerations for designing subsequent trial(s) of CIAT or other interventions for post-stroke aphasia.

  20. Processing distinct linguistic information types in working memory in aphasia.

    Wright, Heather Harris; Downey, Ryan A; Gravier, Michelle; Love, Tracy; Shapiro, Lewis P

    2007-06-01

    BACKGROUND: Recent investigations have suggested that adults with aphasia present with a working memory deficit that may contribute to their language-processing difficulties. Working memory capacity has been conceptualised as a single "resource" pool for attentional, linguistic, and other executive processing-alternatively, it has been suggested that there may be separate working memory abilities for different types of linguistic information. A challenge in this line of research is developing an appropriate measure of working memory ability in adults with aphasia. One candidate measure of working memory ability that may be appropriate for this population is the n-back task. By manipulating stimulus type, the n-back task may be appropriate for tapping linguistic-specific working memory abilities. AIMS: The purposes of this study were (a) to measure working memory ability in adults with aphasia for processing specific types of linguistic information, and (b) to examine whether a relationship exists between participants' performance on working memory and auditory comprehension measures. METHOD #ENTITYSTARTX00026; PROCEDURES: Nine adults with aphasia participated in the study. Participants completed three n-back tasks, each tapping different types of linguistic information. They included the PhonoBack (phonological level), SemBack (semantic level), and SynBack (syntactic level). For all tasks, two n-back levels were administered: a 1-back and 2-back. Each level contained 20 target items; accuracy was recorded by stimulus presentation software. The Subject-relative, Object-relative, Active, Passive Test of Syntactic Complexity (SOAP) was the syntactic sentence comprehension task administered to all participants. OUTCOMES #ENTITYSTARTX00026; RESULTS: Participants' performance declined as n-back task difficulty increased. Overall, participants performed better on the SemBack than PhonoBack and SynBack tasks, but the differences were not statistically significant. Finally

    2011-01-01

    Learning how to use a computer-based communication system can be challenging for people with severe aphasia even if the system is not word-based. This study explored cognitive and linguistic factors relative to how they affected individual patients’ ability to communicate expressively using C-Speak Aphasia, (CSA), an alternative communication computer program that is primarily picture-based. Ten individuals with severe non-fluent aphasia received at least six months of training with CSA. To assess carryover of training, untrained functional communication tasks (i.e., answering autobiographical questions, describing pictures, making telephone calls, describing a short video, and two writing tasks) were repeatedly probed in two conditions: 1) using CSA in addition to natural forms of communication, and 2) using only natural forms of communication, e.g., speaking, writing, gesturing, drawing. Four of the ten participants communicated more information on selected probe tasks using CSA than they did without the computer. Response to treatment also was examined in relation to baseline measures of non-linguistic executive function skills, pictorial semantic abilities, and auditory comprehension. Only nonlinguistic executive function skills were significantly correlated with treatment response. PMID:21506045

  3. How Does Severity of Aphasia Influence Individual Responsiveness to Rehabilitation? Using Big Data to Understand Theories of Aphasia Rehabilitation.

    PubMed

    2016-02-01

    Our ability to make great progress in delivering, optimizing, and predicting rehabilitation outcomes for individuals with aphasia is challenged by factors that influence rehabilitation outcomes. These include patient demographic factors such as age, education, and neurologic factors such as time poststroke, the site and size of the lesion, and the resulting severity of language impairment. Also variable across individuals is the type of treatment and its duration and intensity. This article examines the utility of big data analysis for understanding one of these factors, severity of impairment, and how individual responsiveness to rehabilitation is influenced by a patient's severity of language and cognitive impairment(s). Using examples from two studies and a larger data set, we show that when rehabilitation is tailored to an individual's specific level of impairment, severe and mild patients both show improvements in accuracy and latency. Furthermore, more severe patients tend to show substantial gains on targeted rehabilitation tasks as well as on standardized tests. These results provide support for recent reviews of aphasia rehabilitation studies in concluding that systematic aphasia rehabilitation is indeed effective, and importantly, severity is not a negative prognostic indicator for successful outcomes.

    Five children (three males, two females; four right-, one left-handed; age range 6 to 14 years) who developed aphasia after gross-total excision of left predominantly thalamic tumors are reported. Three patients had Broca aphasia, one had mixed transcortical aphasia, and one patient had conduction aphasia. In the months after surgery, three children improved while receiving radiation and/or chemotherapy, although none recovered completely. Two patients with malignant tumors developed worsening aphasia when the tumor recurred, and later died. Two of three patients tested had visuospatial difficulties in addition to language deficits. Attention and executive functioning were affected in three of three patients tested. Memory, verbal and/or visual functioning, were affected in four of four patients tested. Both patients who were tested showed transient right hemineglect. Two of two patients tested were probably apraxic. The wide range of deficits in these children highlights the importance of the thalamus and other subcortical structures in developing cognition.

    2016-01-01

    Aphasia intervention has made increasing use of technology in recent years. The evidence base, which is largely limited to the investigation of spoken language outcomes, indicates positive treatment effects for people with mild to moderate levels of aphasia. Outcomes for those with severe aphasia, however, are less well documented and – where reported – present less consistent gains for measures of spoken output. This study investigates the effects of a purpose-built gesture therapy technology for people with severe aphasia: GeST+. Study outcomes show significant improvement in gesture production abilities for adults with severe aphasia following computer intervention. They indicate no transfer of effects into naming gains or interactive gesture. Outcomes offer encouraging results for computer therapy methods within this hitherto under-researched population but indicate a need for further refinement of interventions in order to maximize persistence of effects and generalization into everyday communication.

    2012-01-01

    Purpose To investigate the time-course of processing of lexical items in auditorily presented canonical (subject–verb–object) constructions in young, neurologically unimpaired control participants and participants with left-hemisphere damage and agrammatic aphasia. Method A cross modal picture priming (CMPP) paradigm was used to test 114 control participants and 8 participants with agrammatic aphasia for priming of a lexical item (direct object noun) immediately after it is initially encountered in the ongoing auditory stream and at 3 additional time points at 400-ms intervals. Results The control participants demonstrated immediate activation of the lexical item, followed by a rapid loss (decay). The participants with aphasia demonstrated delayed activation of the lexical item. Conclusion This evidence supports the hypothesis of a delay in lexical activation in people with agrammatic aphasia. The delay in lexical activation feeds syntactic processing too slowly, contributing to comprehension deficits in people with agrammatic aphasia. PMID:22355007

    Most studies comparing different levels of aphasia treatment intensity have not controlled the dosage of therapy provided. Consequently, the true effect of treatment intensity in aphasia rehabilitation remains unknown. Aphasia Language Impairment and Functioning Therapy is an intensive, comprehensive aphasia program. We investigated the efficacy of a dosage-controlled trial of Aphasia Language Impairment and Functioning Therapy, when delivered in an intensive versus distributed therapy schedule, on communication outcomes in participants with chronic aphasia. Thirty-four adults with chronic, poststroke aphasia were recruited to participate in an intensive (n=16; 16 hours per week; 3 weeks) versus distributed (n=18; 6 hours per week; 8 weeks) therapy program. Treatment included 48 hours of impairment, functional, computer, and group-based aphasia therapy. Distributed therapy resulted in significantly greater improvements on the Boston Naming Test when compared with intensive therapy immediately post therapy (P=0.04) and at 1-month follow-up (P=0.002). We found comparable gains on measures of participants' communicative effectiveness, communication confidence, and communication-related quality of life for the intensive and distributed treatment conditions at post-therapy and 1-month follow-up. Aphasia Language Impairment and Functioning Therapy resulted in superior clinical outcomes on measures of language impairment when delivered in a distributed versus intensive schedule. The therapy progam had a positive effect on participants' functional communication and communication-related quality of life, regardless of treatment intensity. These findings contribute to our understanding of the effect of treatment intensity in aphasia rehabilitation and have important clinical implications for service delivery models. © 2015 American Heart Association, Inc.

    Clinical observation suggested to us that aphasia recovers relatively better than other deficits early after intravenous recombinant tissue plasminogen activator (IV-rtPA) treatment in stroke patients with minor deficits, while the reverse seemed the case in those with severe deficits. Retrospective analysis of acute ischemic stroke patients with aphasia admitted within 3 hours from symptom onset and treated with IV-rtPA was carried out. Stroke severity, aphasia and global neurological impairment were assessed at admission and 24 hours after thrombolysis. Improvement of aphasia (gain of ⩾ 1 point on the National Institutes of Health Stroke Scale [NIHSS] aphasia score) and global neurological improvement (gain of ⩾ 4 points on the NIHSS) were compared in minor strokes (NIHSS ⩽ 7), moderate strokes (NIHSS 8-15), and major strokes (NIH ⩾ 16). Sixty-nine of 243 stroke patients suffered from aphasia. Improvement of aphasia occurred in 7/16 minor strokes, 11/25 moderate strokes, and 7/28 severe strokes. Improvement of ⩾ 4 points on the NIHSS occurred in 3/16 minor strokes, 17/25 moderate strokes and 15/28 severe strokes. There is a significant (X(2)=4.073, p<0.05) dissociation of recovery of aphasia and that of other neurological deficits between minor versus severe strokes. This confirms the clinically suspected dissociation between a good early recovery from aphasia in minor strokes relative to recovery of other neurological deficits, as opposed to a better recovery from other neurological deficits than from aphasia in patients with severe strokes.

    Exploring the concept of living successfully with aphasia challenges researchers and clinicians to identify positive rather than negative adaptive processes and factors that may inform clinical interventions and other community-based services for people with aphasia. Previous research on this topic has focused on the perspectives of individuals with aphasia, and identified a number of core components of living successfully with aphasia, including doing things, meaningful relationships, striving for a positive way of living, and communication. As service providers, speech-language pathologists may also contribute valuable insights regarding components of living successfully with aphasia and factors influencing individuals' abilities to achieve this goal. This research aimed to explore speech-language pathologists' perspectives about the meaning of living successfully with aphasia, and factors they perceive to influence individuals' abilities to live successfully with aphasia. Twenty-five speech-language pathologists from around Australia participated in semi-structured in-depth interviews on the topic of living successfully with aphasia. All interviews were transcribed verbatim and analysed using interpretative phenomenological analysis to identify themes of relevance. Through the analysis of speech-language pathologist participant transcripts, the following themes emerged as components of living successfully with aphasia: participation and community engagement; communication; meaningful relationships; autonomy or independence; acceptance and embracement of aphasia; self-esteem; happiness; and purpose or meaningfulness. A wide variety of factors were perceived to influence individuals' abilities to live successfully with aphasia. These included support, acceptance, and understanding; personal factors; and speech-language pathology services. Further research is required to extend findings by investigating how speech-language pathologists address identified themes in

    Objective: To investigate the effect of hand action observation training, i.e., mirror neuron system (MNS) based training, on language function of aphasic patients after stroke. In addition, to reveal the tentative mechanism underlying this effect. Methods: Six aphasic patients after stroke, meeting the criteria, undergo 3 weeks' training protocol (30 min per day, 6 days per week). Among them, four patients accepted an ABA training design, i.e., they implemented Protocol A (hand action observation combined with repetition) in the first and third weeks and carried out Protocol B (static object observation combined with repetition) in the second week. Conversely, for the other two patients, BAB training design was adopted, i.e., patients took Protocol B in the first and third weeks and accepted Protocol A in the second week. Picture naming test, western aphasia battery (WAB) and Token Test were applied to evaluate the changes of language function before and after each week's training. Furthermore, two subjects (one aphasic patient and one healthy volunteer) attended a functional MRI (fMRI) experiment, by which we tried to reveal the mechanism underlying possible language function changes after training. Results: Compared with static object observation and repetition training (Protocol B), hand action observation and repetition training (Protocol A) effectively improved most aspects of the language function in all six patients, as demonstrated in the picture naming test, subtests of oral language and aphasia quotient (AQ) of WAB. In addition, the fMRI experiment showed that Protocol A induced more activations in the MNS of one patient and one healthy control when compared to Protocol B. Conclusion: The mirror neuron based therapy may facilitate the language recovery for aphasic patients and this, to some extent, provides a novel direction of rehabilitation for aphasia patients.

    The extent to which non-linguistic auditory processing deficits may contribute to the phenomenology of primary progressive aphasia is not established. Using non-linguistic stimuli devoid of meaning we assessed three key domains of auditory processing (pitch, timing and timbre) in a consecutive series of 18 patients with primary progressive aphasia (eight with semantic variant, six with non-fluent/agrammatic variant, and four with logopenic variant), as well as 28 age-matched healthy controls. We further examined whether performance on the psychoacoustic tasks in the three domains related to the patients’ speech and language and neuropsychological profile. At the group level, patients were significantly impaired in the three domains. Patients had the most marked deficits within the rhythm domain for the processing of short sequences of up to seven tones. Patients with the non-fluent variant showed the most pronounced deficits at the group and the individual level. A subset of patients with the semantic variant were also impaired, though less severely. The patients with the logopenic variant did not show any significant impairments. Significant deficits in the non-fluent and the semantic variant remained after partialling out effects of executive dysfunction. Performance on a subset of the psychoacoustic tests correlated with conventional verbal repetition tests. In sum, a core central auditory impairment exists in primary progressive aphasia for non-linguistic stimuli. While the non-fluent variant is clinically characterized by a motor speech deficit (output problem), perceptual processing of tone sequences is clearly deficient. This may indicate the co-occurrence in the non-fluent variant of a deficit in working memory for auditory objects. Parsimoniously we propose that auditory timing pathways are altered, which are used in common for processing acoustic sequence structure in both speech output and acoustic input. PMID:27060523

  12. [Transcortical aphasia and echolalia; problems of speech initiative].

    PubMed

    Környey, E

    1975-05-01

    Transcortical aphasia accompanied by echolalia occurs with malacias involving the postero-median part of the frontal lobe which includes the supplementary motor field of Penfield and is nourished by the anterior cerebral artery. The syndrome manifests itself in such cases even in fine detials in the same form as does in Pick's atrophy. The same also holds true for cases in which a tumour involves the region mentioned. Sentences or fragments of sentences are echolalised; tendency to perseveration is very marked. It is hardly, if at all, possible to evaluate the verbal understanding of these patients. Analysis of their behaviour supports the assumption that they have not lost the adaptation to some situations. Echolalia is often associated with forced grasping and other compulsory phenomena. Therefore, it may be interpreted as a sign of disinhibition of the acusticomotor reflex present during the development of the speech. Competition between the intentionality and the appearance of compulsory phenomena greatly depends on the general condition of the patient, particularly on the clarity of consciousness. The integrity of the postero-median part of the frontal lobe is indespensable for a normal reaction by speech to stimuli received from the sensory areas. The influence of the supplementary motor field on speech intention seems to be linked to the dominant hemisphere. In case lesions of the territory of the anterior cerebral artery and the cortico-bulbar neuron system are coexisting in the dominant hemisphere, the speech disturbance shifts to complete motor aphasia. In such cases the pathomechanism is analogous to that of the syndrome of Liepmann, i.e., right-sided hemiparesis with left-sided apraxia. So-called transcortical motor aphasia without echolalia can be caused by loss of stimuli from the sensory fields.

Furthermore, two subjects (one aphasic patient and one healthy volunteer) attended a functional MRI (fMRI) experiment, by which we tried to reveal the mechanism underlying possible language function changes after training. Compared with static object observation and repetition training (Protocol B), hand action observation and repetition training (Protocol A) effectively improved most aspects of the language function in all six patients, as demonstrated in the picture naming test, subtests of oral language and aphasia quotient (AQ) of WAB. In addition, the fMRI experiment showed that Protocol A induced more activations in the MNS of one patient and one healthy control when compared to Protocol B. The mirror neuron based therapy may facilitate the language recovery for aphasic patients and this, to some extent, provides a novel direction of rehabilitation for aphasia patients.

    Altholgh Lichtheim recognized that Wernicke's 'reflex arch' (primary auditory area, to Wernicke's area, to Broca's area, to primary motor area) was important for repetition, he recognized that other areas of the brain (for example, area of concepts or semantic area) must be important in comprehension and voluntary speech. He suggested that Wernicke's area (phonemic area) not only projected to Broca's area (as Wernicke suggested) but that it also projected to the area of concepts. A lesion of this latter pathway or in the area of concepts would produce a syndrome where repetition was intact but comprehension was impaired (e.g. transcortical sensory aphasia). Lichtheim also thought that the area of concepts projected directly to Broca's area and that voluntary speech was mediated by this pathway. Although Lichtheim's model could explain the mechanism underlying transcortical aphasia, his schema could not explain anomic aphasia. Unlike Lichtheim's schema, Kussmaul's schema suggested that the area of concepts projects back to Wernicke's area before projecting to Broca's area. With this schema, a patient with a hypothetical lesion which interrupted the pathway from the area of concepts to Wernicke's area (but did not interrupt the pathway from Wernicke's area to the area of concepts) should be anomic, with normal comprehension and repetition. In order for this latter schema to be plausible there should also be a lesion which interrupts the pathway from Wernicke's area to the area of concepts but does not interrupt the pathway which goes from the area of concepts to Wernicke's area. A patient with this hypothetical lesion should comprehend poorly; however, in spite of poor comprehension, naming and repetition should be intact. We report a patient who demonstrates poor comprehension with intact naming and repetition. This patient could also read aloud but could not comprehend written language. Not only could this patient name objects but he could demonstrate their use

    Degeneration of language regions in the dominant hemisphere can result in primary progressive aphasia (PPA), a clinical syndrome characterized by progressive deficits in speech and/or language function. Recent studies have identified three variants of PPA: progressive non-fluent aphasia (PNFA), semantic dementia (SD) and logopenic progressive aphasia (LPA). Each variant is associated with characteristic linguistic features, distinct patterns of brain atrophy, and different likelihoods of particular underlying pathogenic processes, which makes correct differential diagnosis highly clinically relevant. Evaluation of linguistic behavior can be challenging for non-specialists, and neuroimaging findings in single subjects are often difficult to evaluate by eye. We investigated the utility of automated structural MR image analysis to discriminate PPA variants (N=86) from each other and from normal controls (N=115). T1 images were preprocessed to obtain modulated grey matter (GM) images. Feature selection was performed with principal components analysis (PCA) on GM images as well as images of lateralized atrophy. PC coefficients were classified with linear support vector machines, and a cross-validation scheme was used to obtain accuracy rates for generalization to novel cases. The overall mean accuracy in discriminating between pairs of groups was 92.2%. For one pair of groups, PNFA and SD, we also investigated the utility of including several linguistic variables as features. Models with both imaging and linguistic features performed better than models with only imaging or only linguistic features. These results suggest that automated methods could assist in the differential diagnosis of PPA variants, enabling therapies to be targeted to likely underlying etiologies. PMID:19501654

    Though aphasia is primarily characterized by impairments in the comprehension and/or expression of language, research has shown that patients with aphasia also show deficits in cognitive-linguistic domains such as attention, executive function, concept knowledge and memory (Helm-Estabrooks, 2002 for review). Research in aphasia suggests that cognitive impairments can impact the online construction of language, new verbal learning, and transactional success (Freedman & Martin, 2001; Hula & McNeil, 2008; Ramsberger, 2005). In our research, we extend this hypothesis to suggest that general cognitive deficits influence progress with therapy. The aim of our study is to explore learning, a cognitive process that is integral to relearning language, yet underexplored in the field of aphasia rehabilitation. We examine non-linguistic category learning in patients with aphasia (n=19) and in healthy controls (n=12), comparing feedback and non-feedback based instruction. Participants complete two computer-based learning tasks that require them to categorize novel animals based on the percentage of features shared with one of two prototypes. As hypothesized, healthy controls showed successful category learning following both methods of instruction. In contrast, only 60% of our patient population demonstrated successful non-linguistic category learning. Patient performance was not predictable by standardized measures of cognitive ability. Results suggest that general learning is affected in aphasia and is a unique, important factor to consider in the field of aphasia rehabilitation. PMID:23127795

    Little is known about the quality and readability of treatment information in specific neurogenic disorders, such as aphasia. The purpose of this study was to assess quality and readability of English-language Internet information available for aphasia treatment. Forty-three aphasia treatment websites were aggregated using five different country-specific search engines. Websites were then analysed using quality and readability assessments. Statistical calculations were employed to examine website ratings, differences between website origin and quality and readability scores, and correlations between readability instruments. Websites exhibited low quality with few websites obtaining Health On the Net (HON) certification or clear, thorough information as measured by the DISCERN. Regardless of website origin, readability scores were also poor. Approximate educational levels required to comprehend information on aphasia treatment websites ranged from 13 to 16 years of education. Significant differences were found between website origin and readability measures with higher levels of education required to understand information on websites of non-profit organisations. Current aphasia treatment websites were found to exhibit low levels of quality and readability, creating potential accessibility problems for people with aphasia and significant others. Websites including treatment information for aphasia must be improved in order to increase greater information accessibility.

    Purpose This study examined responses of persons with aphasia (PWAs) to a general question about their speech. The goal was to describe their evaluative responses as positive, negative, or neutral/mixed and determine if responses differed, based on time post-onset, aphasia severity, and aphasia type. Methods 71 participants from the AphasiaBank project were included. As part of a larger protocol, investigators asked, “How do you think your speech is these days?” Responses were videotaped and transcribed using CLAN. Two authors coded the evaluative responses and categorized themes in the elaborative content provided by the participants. Results Positive responses accounted for 59% of all responses, followed by neutral/mixed (18%), and negative (17%). Participants also mentioned specific speech problems (35%), improvement (31%), and therapy (8%) in their responses. Time post-onset and aphasia type were not significantly associated with nature of response. Aphasia severity was significantly associated with nature of response, with higher AQ scores in the positive group and vice versa. Conclusions The responses are discussed in the context of self-image and self-expression in PWA and social models in aphasia therapy. Results are also compared with those of others with chronic disabilities and research on resilience, positive affect, and optimism. PMID:22347765

    Impairment of language ability, aphasia, can cause barriers to communication and hence impact on participation in many life situations. This study aimed to describe and explore how persons with aphasia following stroke experience engaging in everyday occupations. Six persons from Southwest Finland who had aphasia due to stroke one to four years previously were interviewed for the study. A modified form of the empirical phenomenological psychological method was used for data analysis. Three main characteristics of experiences of engaging in everyday occupations were identified: (1) encountering new experiences in everyday occupations, (2) striving to handle everyday occupations and (3) going ahead with life. The participants had experienced an altering life-world. Engagement in occupations affected their perceptions of competence and identity, and experiences of belonging and well-being. It was also through engagement in everyday occupations that they had discovered and learnt to handle changes in their everyday life. Aphasia can have a long-term impact on engagement in everyday occupations and participation in society, but conversely, engagement in meaningful occupations can also contribute to adaptation to disability and life changes. Aphasia can have a long-term impact on engagement in everyday occupations and participation in society. Health care professionals need to determine what clients with aphasia think about their occupations and life situations in spite of difficulties they may have verbalizing their thoughts. Experiences of engaging in meaningful occupations can help clients with aphasia in reconstructing their life stories, thereby contributing to adaptation to disability and life changes.

    Aphasia affects family members in addition to the individuals with the communication disorder. In order to develop appropriate services for the relatives of people with aphasia post-stroke, their rehabilitation goals need to be identified. The aim of the current investigation was to identify the rehabilitation goals that family members of individuals with aphasia have for themselves. Forty-eight family members of adults with aphasia post-stroke participated in in-depth semi-structured interviews to identify the rehabilitation goals they had for themselves. All the interviews were transcribed verbatim and analysed using qualitative content analysis. Analysis revealed seven categories of goals that the family members had for themselves: to be included in rehabilitation, to be provided with hope and positivity, to be able to communicate and maintain their relationship with the person with aphasia, to be given information, to be given support, to look after their own well-being, and to be able to cope with new responsibilities. A few participants reported that, at certain times during the rehabilitation process, they did not have any goals for themselves. This study highlights that family members of individuals with aphasia have a number of aphasia-related rehabilitation goals for themselves. In order to provide a family-centred approach to rehabilitation, health professionals, including speech-language pathologists, need systematically to identify and address family members' goals in light of the categories revealed in this investigation. © 2012 Royal College of Speech and Language Therapists.
