They provide the rationales for new disorders, for disorders that had not been included previously in the Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood: Revised Edition (DC:0-3R; ZERO TO THREE, 2005), and for changes in how certain types of disorders are conceptualized. © 2016 Michigan Association for Infant Mental Health.

A review of somatoform disorders in DSM-IV and somatic symptom disorders in proposed DSM-V.

PubMed

Ghanizadeh, Ahmad; Firoozabadi, Ali

2012-12-01

Psychiatric care providers should be trained to use current changes in the somatoform disorders criteria. New diagnostic criteria for Somatic Symptom disorders in the proposed DSM-V is discussed and compared with its older counterpart in DSM-IV. A new category called Somatic Syndrome Disorders is suggested. It includes new subcategories such as "Complex Somatic Symptom Disorder" (CSSD) and "Simple Somatic Symptom Disorder" (SSSD). Some of the subcategories of DSM-IV derived disorders are included in CSSD. While there are some changes in diagnostic criteria, there are concerns and limitations about the new classification needed to be more discussed before implementation. Functional somatic disturbance, the counterpart of converion disorder in DSM-IV, can be highly dependet on the developmental level of children. However, the role of developmental level needs to be considered.

Medical marijuana: review of the science and implications for developmental-behavioral pediatric practice.

PubMed

Hadland, Scott E; Knight, John R; Harris, Sion K

2015-01-01

Marijuana policy is rapidly evolving in the United States and elsewhere, with cannabis sales fully legalized and regulated in some jurisdictions and use of the drug for medicinal purposes permitted in many others. Amidst this political change, patients and families are increasingly asking whether cannabis and its derivatives may have therapeutic utility for a number of conditions, including developmental and behavioral disorders in children and adolescents. This review examines the epidemiology of cannabis use among children and adolescents, including those with developmental and behavioral diagnoses. It then outlines the increasingly well-recognized neurocognitive changes shown to occur in adolescents who use cannabis regularly, highlighting the unique susceptibility of the developing adolescent brain and describing the role of the endocannabinoid system in normal neurodevelopment. The review then discusses some of the proposed uses of cannabis in developmental and behavioral conditions, including attention-deficit hyperactivity disorder and autism spectrum disorder. Throughout, the review outlines gaps in current knowledge and highlights directions for future research, especially in light of a dearth of studies specifically examining neurocognitive and psychiatric outcomes among children and adolescents with developmental and behavioral concerns exposed to cannabis.

2008-01-01

Autism spectrum disorder (ASD) is one of many pervasive developmental disorders (PDD); others include Rett syndrome, childhood disintegrative disorder (also known as Heller's syndrome), pervasive developmental disorder not otherwise specified (PDD-NOS), and the higher functioning Asperger's syndrome. Because ASD is the most common of the developmental disabilities, it is not unusual for dentists to have ASD patients among their patient population. As the name indicates, ASD varies widely in its clinical manifestations; however, dentists are likely to encounter difficulties with communication and socialization. Although communication may be difficult, it is not impossible. A thorough understanding of this complex neurological disorder and displaying patience are vital for the dentist. This article seeks to familiarize readers with ASD characteristics and co-morbid conditions that may affect dental treatment and provide some management strategies for this unique population.

2014-01-01

GM2-Gangliosidosis disease is a rare autosomal recessive genetic disorder that includes two disorders (Tay-Sachs and Sandhoff disease).These disorders cause a progressive deterioration of nerve cells and inherited deficiency in creating hexosaminidases A, B, and AB. Patients who were diagnosed withGM2-Gangliosidosis in the Neurology Department of Mofid Children's Hospital in Tehran, Iran from October 2009 to February 2014were included in our study. The disorder was confirmed by neurometabolic and enzyme level detection of hexosaminidases A, B, and AB in reference to Wagnester Laboratory in Germany. We assessed age, gender, past medical history, developmental status, clinical manifestations, and neuroimaging findings of 9 patients with Sandhoff disease and 9 with Tay Sachs disease. 83% of our patients were the offspring of consanguineous marriages. All of them had a developmental disorder as a chief complaint. 38%of patients had a history of developmental delay or regression and 22% had seizures. The patients with Sandhoff and Tay Sachs disease were followed for approximately 5 years and the follow-up showed all patients were bedridden or had expired due to refractory seizures, pneumonia aspiration, or swallowing disorders. Neuro-imaging findings included bilateral thalamic involvement, brain atrophy, and hypo myelination in near half of our patients (48%). According to the results of this study, we suggest that cherry-red spots, hyperacusis, refractory seizures, and relative parents in children with developmental delay and/or regression should be considered for assessment of GM2-Gangliosidosis disease.

A developmental and genetic classification for midbrain-hindbrain malformations

PubMed Central

Millen, Kathleen J.; Dobyns, William B.

2009-01-01

Advances in neuroimaging, developmental biology and molecular genetics have increased the understanding of developmental disorders affecting the midbrain and hindbrain, both as isolated anomalies and as part of larger malformation syndromes. However, the understanding of these malformations and their relationships with other malformations, within the central nervous system and in the rest of the body, remains limited. A new classification system is proposed, based wherever possible, upon embryology and genetics. Proposed categories include: (i) malformations secondary to early anteroposterior and dorsoventral patterning defects, or to misspecification of mid-hindbrain germinal zones; (ii) malformations associated with later generalized developmental disorders that significantly affect the brainstem and cerebellum (and have a pathogenesis that is at least partly understood); (iii) localized brain malformations that significantly affect the brain stem and cerebellum (pathogenesis partly or largely understood, includes local proliferation, cell specification, migration and axonal guidance); and (iv) combined hypoplasia and atrophy of putative prenatal onset degenerative disorders. Pertinent embryology is discussed and the classification is justified. This classification will prove useful for both physicians who diagnose and treat patients with these disorders and for clinical scientists who wish to understand better the perturbations of developmental processes that produce them. Importantly, both the classification and its framework remain flexible enough to be easily modified when new embryologic processes are described or new malformations discovered. PMID:19933510

Developmental disorders, including intellectual disability and autism spectrum disorders, may limit an individual's capacity to conduct daily activities. The emotional and economic burden on families caring for an individual with a developmental disorder is substantial, and quality of life may be limited by a lack of services. Therefore, finding effective treatments to help this population should be a priority. Recent work has shown parent skills training interventions improve developmental, behavioural and family outcomes. The purpose of this review protocol is to extend previous findings by systematically analysing randomised controlled trials of parent skills training programmes for parents of children with developmental disorders including intellectual disabilities and autism spectrum disorders and use meta-analytic techniques to identify programme components reliably associated with successful outcomes of parent skills training programmes. We will include all studies conducted using randomised control trials designs that compare a group of parents receiving a parent skills training programme to a group of parents in a no-treatment control, waitlist control or treatment as usual comparison group. To locate studies, we will conduct an extensive electronic database search and then use snowball methods, with no limits to publication year or language. We will present a narrative synthesis including visual displays of study effects on child and parental outcomes and conduct a quantitative synthesis of the effects of parent skills training programmes using meta-analytic techniques. No ethical issues are foreseen and ethical approval is not required given this is a protocol for a systematic review. The findings of this study will be disseminated through peer-reviewed publications and international conference presentations. Updates of the review will be conducted, as necessary, to inform and guide practice. PROSPERO (CRD42014006993). Published by the BMJ Publishing Group Limited.

2012-07-01

Childhood developmental and behavioural disorders (CDABD) have been increasingly recognised in recent years. This study evaluated the profiles and outcomes of children referred for developmental and behavioural concerns to a tertiary child developmental centre in Singapore. This is the first such regional database. Baseline information, obtained through a questionnaire, together with history at first consultation, provided information for referral, demographic and presentation profiles. Clinical formulations were then made. Definitive developmental and medical diagnoses, as well as outcomes based on clinical assessment and standardised testing, were recorded at one year post first consultation. Out of 1,304 referrals between January 1, 2003 and December 1, 2004, 45% were 2-4 years old and 74% were boys. The waiting time from referral to first consultation exceeded four months in 52% of children. Following clinical evaluation, 7% were found to be developmentally appropriate. The single most common presenting concern was speech and language (S&L) delay (29%). The most common clinical developmental diagnosis was autism spectrum disorder (ASD) (30%), followed by isolated S&L disorder, global developmental delay (GDD) and cognitive impairment (CI). Recommendations included S&L therapy (57%), occupational therapy (50%) and psychological/behavioural services (40%). At one year, ASD remained the most common definitive developmental diagnosis (31%), followed by S&L disorder, CI and GDD. Most were children with high-prevalence, low-moderate severity disorders who could potentially achieve fair-good prognosis with early intervention. Better appreciation of the profile and outcome of children with CDABD in Singapore could enable better resource planning for diagnosis and intervention.

Development in Children and Adolescents Whose Mothers Have Borderline Personality Disorder

PubMed Central

2009-01-01

A mother's mental illness may have a profound effect on her child's development, including an increased risk of the child developing the same disorder. From a developmental psychopathology perspective, offspring provide an opportunity to examine pathways to disorder versus resilience. Borderline personality disorder (BPD) is a severe disorder diagnosed in early adulthood involving stormy relationships, an unstable sense of identity, and self-destructive behavior. Interestingly, the domains of dysfunction are conceptually similar to developmental tasks in early childhood reworked in adolescence: attachment, self development, and self-regulation. Early deviation may increase the risk for later disorder. There are five empirical studies of children whose mothers have BPD, two conducted from a developmental perspective. This article proposes a theoretical framework and an innovative methodology with which to extend this research, and suggests an intervention to bring development back on track if necessary.

Ontogenetic developments of rest-activity, sleep-wakefulness, temperature and several hormone rhythms in humans were reviewed. The reported effects of environment on these alterations were also summarized. Then, disorders or conditions which often encounter during early stage of life and reveal circadian rhythm disruptions were described. These disorders or conditions included severe brain damage, visual disturbance, developmental disorders(autistic spectrum disorder and attention deficit/hyperactivity disorder), Rett syndrome, Angelman syndrome, Smith-Magenis syndrome, epilepsy, Yonaki, and inadequate sleep hygiene. Finally, it was emphasized that we should pay special attention on the development of youngsters who showed sleep disturbance during early stage of life with special reference to the later occurrence of developmental disorders.

Nonspeech oral motor treatment issues related to children with developmental speech sound disorders.

PubMed

Ruscello, Dennis M

2008-07-01

This article examines nonspeech oral motor treatments (NSOMTs) in the population of clients with developmental speech sound disorders. NSOMTs are a collection of nonspeech methods and procedures that claim to influence tongue, lip, and jaw resting postures; increase strength; improve muscle tone; facilitate range of motion; and develop muscle control. In the case of developmental speech sound disorders, NSOMTs are employed before or simultaneous with actual speech production treatment. First, NSOMTs are defined for the reader, and there is a discussion of NSOMTs under the categories of active muscle exercise, passive muscle exercise, and sensory stimulation. Second, different theories underlying NSOMTs along with the implications of the theories are discussed. Finally, a review of pertinent investigations is presented. The application of NSOMTs is questionable due to a number of reservations that include (a) the implied cause of developmental speech sound disorders, (b) neurophysiologic differences between the limbs and oral musculature, (c) the development of new theories of movement and movement control, and (d) the paucity of research literature concerning NSOMTs. There is no substantive evidence to support NSOMTs as interventions for children with developmental speech sound disorders.

Onto-clust--a methodology for combining clustering analysis and ontological methods for identifying groups of comorbidities for developmental disorders.

PubMed

Peleg, Mor; Asbeh, Nuaman; Kuflik, Tsvi; Schertz, Mitchell

2009-02-01

Children with developmental disorders usually exhibit multiple developmental problems (comorbidities). Hence, such diagnosis needs to revolve on developmental disorder groups. Our objective is to systematically identify developmental disorder groups and represent them in an ontology. We developed a methodology that combines two methods (1) a literature-based ontology that we created, which represents developmental disorders and potential developmental disorder groups, and (2) clustering for detecting comorbid developmental disorders in patient data. The ontology is used to interpret and improve clustering results and the clustering results are used to validate the ontology and suggest directions for its development. We evaluated our methodology by applying it to data of 1175 patients from a child development clinic. We demonstrated that the ontology improves clustering results, bringing them closer to an expert generated gold-standard. We have shown that our methodology successfully combines an ontology with a clustering method to support systematic identification and representation of developmental disorder groups.

There is variability in the attainment of developmental milestones in the CDKL5 disorder.

Fehr, Stephanie; Leonard, Helen; Ho, Gladys; Williams, Simon; de Klerk, Nick; Forbes, David; Christodoulou, John; Downs, Jenny

2015-01-01

Individuals with the CDKL5 disorder have been described as having severely impaired development. A few individuals have been reported having attained more milestones including walking and running. Our aim was to investigate variation in attainment of developmental milestones and associations with underlying genotype. Data was sourced from the International CDKL5 Disorder Database, and individuals were included if they had a pathogenic or probably pathogenic CDKL5 mutation and information on early development. Kaplan-Meier time-to-event analyses investigated the occurrence of developmental milestones. Mutations were grouped by their structural/functional consequence, and Cox regression was used to investigate the relationship between genotype and milestone attainment. The study included 109 females and 18 males. By 5 years of age, only 75% of the females had attained independent sitting and 25% independent walking whilst a quarter of the males could sit independently by 1 year 3 months. Only one boy could walk independently. No clear relationship between mutation group and milestone attainment was present, although females with a late truncating mutation attained the most milestones. Attainment of developmental milestones is severely impaired in the CDKL5 disorder, with the majority who did attain skills attaining them at a late age. It appears as though males are more severely impaired than the females. Larger studies are needed to further investigate the role of genotype on clinical variability.

Left temporal arachnoid cyst and specific learning disorders associated with pervasive developmental disorders - not otherwise specified (PDD-NOS): contributions of an integrative neuro-psychomotor, neuropsychological, psychopathological and neurosurgical approach about a case report in a child (François). With DSM-IV and DSM-IV-TR, the terminology of pervasive developmental disorders (PDD) covers two main categories of infantile disorders: disorders of "strictly" autistic nature and pervasive developmental disorders - not otherwise specified (PDD-NOS). Under the terminology of multiple complex developmental disorder (MCDD), it is proposed to classify children presenting symptoms approaching the psychotic disharmonies and usually diagnosed as PDD-NOS. Such a category of developmental disorders is now included without nosographic distinction in the autistic spectrum in the Diagnostic and Statistical Manual of mental disorders (DSM-V). We are reporting a case report of a 6-year-old boy which shows a PDD-NoS/MCDD complex symptomatology type. This child presents multiple disorders: minor neurological signs (soft signs), neuro-psychomotor disorders, developmental coordination disorder (DCD), communication, thought, and regulation of emotions disorders, attention deficit disorders (ADD); in the presence of a high verbal intellectual potential, which makes it difficult to establish a clear diagnosis. A cerebral magnetic resonance imaging (MRI) was carried out due to the presence of minor neurological signs (soft signs) and of neurodevelopmental multiple disorders. The MRI revealed a voluminous arachnoid temporo-polar left cyst with a marked mass effect on the left temporal lobe. A neurosurgical intervention allowed to observe the gradual disappearance of the specific symptomatology (in particular soft signs, neuro-psychomotor functions and autistic symptoms) secondary to the interference of the cyst's pressure with intracranial areas involving neurological and psychopathological abnormalities, underlying at the same time the reversibility of the disorders after decompression as demonstrated in some studies. There are always, with a quantitative and qualitative decrease, an emotional dysregulation, a DCD, an ADD as well as impairments in the executive functions. This clinical case underlines the necessity of an evaluation in a transdisciplinary way and to follow the developmental evolution of the child in order to focus adapted therapeutics. Furthermore, with neurodevelopmental disorders not specified, it is important to examine the presence of soft signs with standardized neuro-psychomotor assessment, and then, to propose an MRI investigation. To our knowledge, this is the first report in the literature with a school age child of an unusual association between a temporal arachnoid cyst associated with PDD-NOS/MCDD.

Eating disorders and the serotonin connection: state, trait and developmental effects

PubMed Central

Steiger, Howard

2004-01-01

Alterations in brain serotonin (5-hydroxytryptamine [5-HT]) function are thought to contribute to diverse aspects of eating disorders, including binge eating, perfectionism, impulsivity and mood-regulation problems. In addition, 5-HT anomalies in individuals with eating disorders are believed to have multiple determinants associated with secondary (state-related) effects of their nutritional status, hereditary effects (related to such trait variations as impulsivity or perfectionism) and, possibly, long-term neurobiologic sequelae of developmental stressors (such as childhood abuse). On the strength of the available neurobiologic and genetic data, this paper presents the idea that 5-HT variations in those with eating disorders represent (1) a structured coaggregation of biologic, psychologic and social influences and (2) converging state, trait and developmental effects. Data are taken to support a multidimensional model of 5-HT function in eating disorders that, it is argued, can serve as a prototype for etiologic modelling, diagnostic classification and clinical decision-making bearing not only upon eating disorders but also upon other psychiatric disturbances.

Autism, an overwhelming condition: history, etiopathogenesis, types, diagnosis, therapy and prognosis.

PubMed

Amihăesei, Ioana Cristina; Stefanachi, Elena

2013-01-01

Autism is defined as a neurologic developmental disorder affecting brain and behavior, becoming usually apparent before 3 years of age, with stable evolution and no remission. No neurologic morphologic abnormality was associated with the disease. Several types of disease being described, autism is part of a larger spectrum known as autism spectrum disorders (ASD), or pervasive developmental disorders (PDD). The disease was first described long before it was defined and it has received its modern name. Main cause in the development of autism is considered to be genetic, up to 90 %. However, environmental factors could be incriminated, sometimes. The five types included in ASD are: Asperger syndrome, pervasive developmental disorder-not otherwise specified (PDD-NOS), typical autism, Rett syndrome and childhood disintegrative disorder (CDD). The classical triad of symptoms includes: social interaction impairments, communication impairments and repetitive, stereotype behavior. Diagnosis is based on interview of the parents and specialized observation of the suspected children. Main tools used in therapy are the family and the educational system. Well established, specialized programs of therapy were developed in time. Prognosis of autism is severe, since no cure is possible; nevertheless spontaneous recoveries do occur, in some cases.

Impact of bilirubin-induced neurologic dysfunction on neurodevelopmental outcomes

PubMed Central

Loe, Irene M.

2015-01-01

Bilirubin-induced neurologic dysfunction (BIND) is the constellation of neurologic sequelae following milder degrees of neonatal hyperbilirubinemia than are associated with kernicterus. Clinically, BIND may manifest after the neonatal period as developmental delay, cognitive impairment, disordered executive function, and behavioral and psychiatric disorders. However, there is controversy regarding the relative contribution of neonatal hyperbilirubinemia versus other risk factors to the development of later neurodevelopmental disorders in children with BIND. In this review, we focus on the empiric data from the past 25 years regarding neurodevelopmental outcomes and BIND, including specific effects on developmental delay, cognition, speech and language development, executive function, and th neurobehavioral disorders, such as attention deficit/hyperactivity disorder and autism.

Developmental programming of the metabolic syndrome - critical windows for intervention

Metabolic disease results from a complex interaction of many factors, including genetic, physiological, behavioral and environmental influences. The recent rate at which these diseases have increased suggests that environmental and behavioral influences, rather than genetic causes, are fuelling the present epidemic. In this context, the developmental origins of health and disease hypothesis has highlighted the link between the periconceptual, fetal and early infant phases of life and the subsequent development of adult obesity and the metabolic syndrome. Although the mechanisms are yet to be fully elucidated, this programming was generally considered an irreversible change in developmental trajectory. Recent work in animal models suggests that developmental programming of metabolic disorders is potentially reversible by nutritional or targeted therapeutic interventions during the period of developmental plasticity. This review will discuss critical windows of developmental plasticity and possible avenues to ameliorate the development of postnatal metabolic disorders following an adverse early life environment.

Introduction Health disorders early in life have tremendous impact on children’s developmental trajectories. Almost 80% of children with health disorders lack the developmental skills to take full advantage of school-based education relative to 27% of children without a health disorder. In Canada, there is currently a dearth of nationally representative data on the social determinants of early childhood development for children with health disorders. Evidence from Canada and other countries indicate that poorer developmental outcomes in typically developing children are associated with lower socioeconomic status (SES). However, to date, it is not known whether this relationship is stronger among children with health disorders. The study’s objectives are to estimate the prevalence and to investigate social determinants of developmental outcomes for young children with health disorders, using the Early Development Instrument (EDI). Methods and analysis Study objectives will be achieved through three steps. First, using existing EDI data for 10 provinces and 2 territories collected from 2004 to 2015, we will investigate differences in developmental health outcomes among children with identified health disorders. Second, population-level EDI data will be linked with neighbourhood sociodemographic census data to explore associations between socioeconomic characteristics and rates of specific diagnoses among children aged 5–6 years, including trends over time. Third, for 3 of these 12 regions, additional health and/or education databases will be linked at an individual level. These data will be used to establish differences in EDI outcomes in relation to the age-of-onset of diagnosis, and presence of intervention or treatment. Ethics and dissemination Study methodologies have been approved by the Hamilton Integrated Research Ethics Board. The results of the analyses of developmental health outcomes for children with health disorders combined with SES will have implications for both health service delivery and school-based intervention strategies. Results will contribute to a framework for public policy. PMID:29844103

Recognizing the Common Origins of Dystonia and the Development of Human Movement: A Manifesto of Unmet Needs in Isolated Childhood Dystonias

Lin, Jean-Pierre; Nardocci, Nardo

2016-01-01

Dystonia in childhood may be severely disabling and often unremitting and unrecognized. Considered a rare disorder, dystonic symptoms in childhood are pervasive in many conditions including disorders of developmental delay, cerebral palsy (CP), autism, neurometabolic, neuroinflammatory, and neurogenetic disorders. Collectively, there is a need to recognize the role of early postures and movements which characterize phases of normal fetal, infant, and child development as a backdrop to the many facets of dystonia in early childhood neurological disorders and to be aware of the developmental context of dystonic symptoms. The role of cocontraction is explored throughout infancy, childhood, young adulthood, and in the elderly. Under-recognition of pervasive dystonic disorders of childhood, including within CP is reviewed. Original descriptions of CP by Gowers are reviewed and contemporary physiological demonstrations are used to illustrate support for an interpretation of the tonic labyrinthine response as a manifestation of dystonia. Early recognition and molecular diagnosis of childhood dystonia where possible are desirable for appropriate clinical stratification and future precision medicine and functional neurosurgery where appropriate. A developmental neurobiological perspective could also be useful in exploring new clinical strategies for adult-onset dystonia disorders focusing on environmental and molecular interactions and systems behaviors.

Pediatric dysphagia—feeding and swallowing difficulties that begin at birth, last throughout childhood, and continue into maturity—is one of the most common, least understood complications in children with developmental disorders. We argue that a major cause of pediatric dysphagia is altered hindbrain patterning during pre-natal development. Such changes can compromise craniofacial structures including oropharyngeal muscles and skeletal elements as well as motor and sensory circuits necessary for normal feeding and swallowing. Animal models of developmental disorders that include pediatric dysphagia in their phenotypic spectrum can provide mechanistic insight into pathogenesis of feeding and swallowing difficulties. A fairly common human genetic developmental disorder, DiGeorge/22q11.2 Deletion Syndrome (22q11DS) includes a substantial incidence of pediatric dysphagia in its phenotypic spectrum. Infant mice carrying a parallel deletion to 22q11DS patients have feeding and swallowing difficulties. Altered hindbrain patterning, neural crest migration, craniofacial malformations, and changes in cranial nerve growth prefigure these difficulties. Thus, in addition to craniofacial and pharyngeal anomalies that arise independently of altered neural development, pediatric dysphagia may reflect disrupted hindbrain patterning and its impact on neural circuit development critical for feeding and swallowing. The mechanisms that disrupt hindbrain patterning and circuitry may provide a foundation to develop novel therapeutic approaches for improved clinical management of pediatric dysphagia. PMID:26554723

Melatonin Treatment in Children with Developmental Disabilities

Melatonin is commonly recommended to treat sleep problems in children with developmental disabilities. However, relatively few studies document the efficacy and safety of melatonin in pediatric populations with developmental diagnoses. This chapter reviews recent studies of melatonin efficacy across a wide breadth of developmental disabilities. Overall, short treatment trials (1 week to 3 months) of melatonin were associated with a significant decrease in sleep onset latency time for each of the disorders reviewed, with one notable exception, tuberous sclerosis. In general, reported side effects were uncommon and mild in nature. Across disorders, additional research is needed to draw disability-specific conclusions. However, studies to date provide positive support for future trials that include larger groups of children with specific disabilities/syndromes. PMID:26055866

Autistic spectrum disorders.

PubMed

Singhania, Rajeshree

2005-04-01

Autistic spectrum disorders is a complex developmental disorder with social and communication dysfunction at its core. It has a wide clinical spectrum with a common triad of impairments -- social communication, social interaction and social imagination. Even mild or subtle difficulties can have a profound and devastating impact on the child. To be able to provide suitable treatments and interventions the distinctive way of thinking and learning of autistic children has to be understood. The core areas of social, emotional, communication and language deficits have to be addressed at all levels of functioning. The important goals of assessment include a categorical diagnosis of autism that looks at differential diagnosis, a refined precise documentation of the child's functioning in various developmental domains and ascertaining presence of co-morbid conditions. The interventions have to be adapted to the individual's chronological age, developmental phase and level of functioning. The strategies of curriculum delivery and teaching the child with autism is distinctive and includes presence of structure to increase predictability and strategies to reduce arousal of anxiety.

The developing brain is extremely sensitive to many chemicals. Exposure to neurotoxicants during development has been implicated in various neuropsychiatric and neurological disorders, including autism spectrum disorder, attention deficit hyperactive disorder, schizophrenia, Parkinson's disease, and Alzheimer's disease. Although rodents have been widely used for developmental neurotoxicity testing, experiments using large numbers of rodents are time-consuming, expensive, and raise ethical concerns. Using alternative non-mammalian animal models may relieve some of these pressures by allowing testing of large numbers of subjects while reducing expenses and minimizing the use of mammalian subjects. In this review, we discuss some of the advantages of using zebrafish in developmental neurotoxicity testing, focusing on central nervous system development, neurobehavior, toxicokinetics, and toxicodynamics in this species. We also describe some important examples of developmental neurotoxicity testing using zebrafish combined with gene expression profiling, neuroimaging, or neurobehavioral assessment. Zebrafish may be a systems toxicology model that has the potential to reveal the pathways of developmental neurotoxicity and to provide a sound basis for human risk assessments. © 2014 Japanese Teratology Society.

Copy-number variations are enriched for neurodevelopmental genes in children with developmental coordination disorder.

Developmental coordination disorder is a common neurodevelopment disorder that frequently co-occurs with other neurodevelopmental disorders including attention-deficit hyperactivity disorder (ADHD). Copy-number variations (CNVs) have been implicated in a number of neurodevelopmental and psychiatric disorders; however, the proportion of heritability in developmental coordination disorder (DCD) attributed to CNVs has not been explored. This study aims to investigate how CNVs may contribute to the genetic architecture of DCD. CNV analysis was performed on 82 extensively phenotyped Canadian children with DCD, with or without co-occurring ADHD and/or reading disorder, and 2988 healthy European controls using identical genome-wide SNP microarrays and CNV calling algorithms. An increased rate of large and rare genic CNVs (p=0.009) was detected, and there was an enrichment of duplications spanning brain-expressed genes (p=0.039) and genes previously implicated in other neurodevelopmental disorders (p=0.043). Genes and loci of particular interest in this group included: GAP43, RBFOX1, PTPRN2, SHANK3, 16p11.2 and distal 22q11.2. Although no recurrent CNVs were identified, 26% of DCD cases, where sample availability permitted segregation analysis, were found to have a de novo rare CNV. Of the inherited CNVs, 64% were from a parent who also had a neurodevelopmental disorder. These findings suggest that there may be shared susceptibility genes for DCD and other neurodevelopmental disorders and highlight the need for thorough phenotyping when investigating the genetics of neurodevelopmental disorders. Furthermore, these data provide compelling evidence supporting a genetic basis for DCD, and further implicate rare CNVs in the aetiology of neurodevelopmental disorders.

Seizure disorder and developmental disorder are two of the most common chronic disorders in childhood. Data on perceived parental burden and specific effects on daily life is scarce. We performed a structured interview, consecutively talking to all parents of pediatric outpatients of our university hospital diagnosed with seizure or developmental disorder. Three hundred seven parents (of 317 affected children: 53 with seizure disorder, 44 with specific developmental disorder, 35 with learning disorder, 71 with intellectual disability, 15 with seizure + specific developmental disorder, 23 with seizure + learning disorder, 76 with seizure disorder + intellectual disability) were interviewed. Parents of children with both seizure disorder and intellectual disability stated the highest constraints in daily life, regarding friends, hobbies, emotional pressure, occupation, partnership, habitation, and financial burden. Due to diagnosis of seizure or developmental disorder, 155/307 (51%) parents reduced their working hours/stopped working, 62/307 (20%) changed their habitation, and 46/307 (15%) broke up. As judged by parents, 148/317 (47%) children are being discriminated against, even own family/friends and educators are held responsible. Parents perceive changes in their daily life and discrimination of their children due to their children's seizure and developmental disorders. An intellectual disability combined with seizure disorder caused the highest constraint. What is Known: • Seizure and/or developmental disorders of children may adversely influence quality of life for affected parents. • Caring for a child with special health care needs can take complete attention and own parental needs may therefore be difficult to meet. What is New: • Two out of three parents stated changes of their daily life such as quitting work, change of habitation, or breakup of partnership due to their child's diagnosis. • As judged by the parents, one in two children with developmental disorder of any kind is being discriminated against, even teachers and own family are held responsible.

Eating disorders in adolescence: attachment issues from a developmental perspective

Gander, Manuela; Sevecke, Kathrin; Buchheim, Anna

2015-01-01

In the present article we review findings from an emerging body of research on attachment issues in adolescents with eating disorders from a developmental perspective. Articles for inclusion in this review were identified from PsychINFO (1966–2013), Sciencedirect (1970–2013), Psychindex (1980–2013), and Pubmed (1980–2013). First, we will outline the crucial developmental changes in the attachment system and discuss how they might be related to the early onset of the disease. Then we will report on the major results from attachment studies using self-report and narrative instruments in that age group. Studies with a developmental approach on attachment will be analyzed in more detail. The high incidence of the unresolved attachment pattern in eating disorder samples is striking, especially for patients with anorexia nervosa. Interestingly, this predominance of the unresolved category was also found in their mothers. To date, these transgenerational aspects are still poorly understood and therefore represent an exciting research frontier. Future studies that include larger adolescent samples and provide a more detailed description including symptom severity and comorbidity would contribute to a better understanding of this complex and painful condition.

Toward developmental models of psychiatric disorders in zebrafish

PubMed Central

Norton, William H. J.

Psychiatric disorders are a diverse set of diseases that affect all aspects of mental function including social interaction, thinking, feeling, and mood. Although psychiatric disorders place a large economic burden on society, the drugs available to treat them are often palliative with variable efficacy and intolerable side-effects. The development of novel drugs has been hindered by a lack of knowledge about the etiology of these diseases. It is thus necessary to further investigate psychiatric disorders using a combination of human molecular genetics, gene-by-environment studies, in vitro pharmacological and biochemistry experiments, animal models, and investigation of the non-biological basis of these diseases, such as environmental effects. Many psychiatric disorders, including autism spectrum disorder, attention-deficit/hyperactivity disorder, mental retardation, and schizophrenia can be triggered by alterations to neural development. The zebrafish is a popular model for developmental biology that is increasingly used to study human disease. Recent work has extended this approach to examine psychiatric disorders as well. However, since psychiatric disorders affect complex mental functions that might be human specific, it is not possible to fully model them in fish. In this review, I will propose that the suitability of zebrafish for developmental studies, and the genetic tools available to manipulate them, provide a powerful model to study the roles of genes that are linked to psychiatric disorders during neural development. The relative speed and ease of conducting experiments in zebrafish can be used to address two areas of future research: the contribution of environmental factors to disease onset, and screening for novel therapeutic compounds.

Proposed changes to the American Psychiatric Association diagnostic criteria for autism spectrum disorder: implications for young children and their families.

PubMed

Grant, Roy; Nozyce, Molly

2013-05-01

The American Psychiatric Association has revised the diagnostic criteria for their DSM-5 manual. Important changes have been made to the diagnosis of the current (DSM-IV) category of Pervasive Developmental Disorders. This category includes Autistic Disorder (autism), Asperger's Disorder, and Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS). The DSM-5 deletes Asperger's Disorder and PDD-NOS as diagnostic entities. This change may have unintended consequences, including the possibility that the new diagnostic framework will adversely affect access to developmental interventions under Individuals with Disabilities Education Act (IDEA) programs, Early Intervention (for birth to 2 years olds) and preschool special education (for 3 and 4 years olds). Changing the current diagnosis of PDD-NOS to a "Social Communication Disorder" focused on language pragmatics in the DSM-5 may restrict eligibility for IDEA programs and limit the scope of services for affected children. Young children who meet current criteria for PDD-NOS require more intensive and multi-disciplinary services than would be available with a communication domain diagnosis and possible service authorization limited to speech-language therapy. Intensive behavioral interventions, inclusive group setting placements, and family support services are typically more available for children with an autism spectrum disorder than with diagnoses reflecting speech-language delay. The diagnostic distinction reflective of the higher language and social functioning between Asperger's Disorder and autism is also undermined by eliminating the former as a categorical diagnosis and subsuming it under autism. This change may adversely affect treatment planning and misinform parents about prognosis for children who meet current criteria for Asperger's Disorder.

Impact of bilirubin-induced neurologic dysfunction on neurodevelopmental outcomes.

Bilirubin-induced neurologic dysfunction (BIND) is the constellation of neurologic sequelae following milder degrees of neonatal hyperbilirubinemia than are associated with kernicterus. Clinically, BIND may manifest after the neonatal period as developmental delay, cognitive impairment, disordered executive function, and behavioral and psychiatric disorders. However, there is controversy regarding the relative contribution of neonatal hyperbilirubinemia versus other risk factors to the development of later neurodevelopmental disorders in children with BIND. In this review, we focus on the empiric data from the past 25 years regarding neurodevelopmental outcomes and BIND, including specific effects on developmental delay, cognition, speech and language development, executive function, and the neurobehavioral disorders, such as attention deficit/hyperactivity disorder and autism.

Parent perceptions of the quality of life of pet dogs living with neuro-typically developing and neuro-atypically developing children: An exploratory study

Wright, Hannah F.; Mills, Daniel S.

2017-01-01

There is growing scientific and societal recognition of the role that pet dogs can play in healthy development of children; both those who are neuro-typically developing and those who live with a neuro-developmental disorder, such as autism or attention deficit hyperactivity disorder. However, little attention has been paid to how living with children positively and negatively affects quality of life of a pet dog. In this exploratory study we conducted semi-structured interviews with parents of neuro-typically developing children (n = 18) and those with a neuro-developmental disorder (n = 18) who owned a pet dog, until no new factors were identified. Living with children brought potentially positive benefits to the dog’s life including: imposition of a routine, participation in recreational activities and the development of a strong bond between the child and the dog. The importance of maintaining a routine was particularly prevalent in families with children with neuro-developmental disorders. Potential negative factors included having to cope with child meltdowns and tantrums, over stimulation from child visitors, harsh contact and rough and tumble play with the child. The regularity and intensity of meltdowns and tantrums was particularly evident in responses from parents with children with a neuro-developmental disorder. However, child visitors and rough play and contact were mentioned similarly across the groups. Protective factors included having a safe haven for the dog to escape to, parent’s awareness of stress signs and child education in dog-interaction. Parents were also asked to complete a stress response scale to provide an initial quantitative comparison of stress responses between dogs living with the two family-types. Parents with neuro-typically developing children more frequently observed their dog rapidly running away from a situation and less frequently observed their dog widening their eyes, than parents with children with a neuro-developmental disorder. We propose the development of a stress audit based on the findings reported here, to prevent potential dangerous situations, which may lead to dog bites and dog relinquishment and allow owners to maximise the benefits of dog ownership.

Schuntermann, Peter

2007-01-01

Parents raising a child with significant developmental challenges are profoundly aware of the often sustained impact of that child's special needs upon their other children. Supported by recent research on siblings of developmentally challenged children, clinicians are advocating family-based interventions that take into account the needs of siblings. This article reviews the experience of siblings who live with brothers or sisters diagnosed with pervasive developmental disorder or mental retardation. Contributions from research on typical siblings are drawn upon when appropriate. Six domains of the sibling experience are identified. These domains explore relational shifts within sibling relationships and through the expectable differential parental treatment of each child. Shifts considered in this review include the interrelationships with the extended family, peers, and friendships, all of which contribute to shaping the meaning that siblings give to living with developmentally challenged brothers or sisters across time.

Despite the comorbidity between motor difficulties and certain disabilities, limited research has examined links between early motor, cognitive, and social skills in preschool-aged children with developmental disabilities. The present study examined the relative contributions of gross motor and fine motor skills to the prediction of improvements in children's cognitive and social skills among 2,027 pre-kindergarten children with developmental disabilities, including specific learning disorder, speech/language impairment, intellectual disability, and autism spectrum disorder. Results indicated that for pre-kindergarten children with developmental disabilities, fine motor skills, but not gross motor skills, were predictive of improvements in cognitive and social skills, even after controlling for demographic information and initial skill levels. Moreover, depending on the type of developmental disability, the pattern of prediction of gross motor and fine motor skills to improvements in children's cognitive and social skills differed. Implications are discussed. Copyright © 2016 Elsevier Ltd. All rights reserved.

[Asperger's syndrome: continuum or spectrum of autistic disorders?].

PubMed

Bryńska, Anita

2011-01-01

Pervasive Developmental Disorders (PPD) refers to the group of disorders characterised by delayed or inappropriate development of multiple basic functions including socialisation, communication, behaviour and cognitive functioning. The term,,autistic spectrum disorders" was established as a result of the magnitude of the intensity of symptoms and their proportions observed in all types of pervasive developmental disorders. Asperger's Syndrome (AS) remains the most controversial diagnosis in terms of its place within autism spectrum disorders. AS if often described as an equivalent of High Functioning Autism (HFA) or as a separate spectrum-related disorder with unique diagnostic criteria. Another important issue is the relationship between AS and speech disorders. Although it is relatively easy to draw a line between children with classical autism and speech disorders, the clear cut frontiers between them still remain to be found. The main distinguishing feature is the lack of stereotypic interests and unimpaired social interaction observed in children with speech disorders, such as semantic-pragmatic disorder.

Recent theories hypothesize that procedural learning may support the frequent overlap between neurodevelopmental disorders. The neural circuitry supporting procedural learning includes, among others, cortico-cerebellar and cortico-striatal loops. Alteration of these loops may account for the frequent comorbidity between Developmental Coordination Disorder (DCD) and Developmental Dyslexia (DD). The aim of our study was to investigate cerebral changes due to the learning and automatization of a sequence learning task in children with DD, or DCD, or both disorders. fMRI on 48 children (aged 8-12) with DD, DCD or DD + DCD was used to explore their brain activity during procedural tasks, performed either after two weeks of training or in the early stage of learning. Firstly, our results indicate that all children were able to perform the task with the same level of automaticity, but recruit different brain processes to achieve the same performance. Secondly, our fMRI results do not appear to confirm Nicolson and Fawcett's model. The neural correlates recruited for procedural learning by the DD and the comorbid groups are very close, while the DCD group presents distinct characteristics. This provide a promising direction on the neural mechanisms associated with procedural learning in neurodevelopmental disorders and for understanding comorbidity. Published by Elsevier Ltd.

Allostatic load in parents of children with developmental disorders: moderating influence of positive affect.

PubMed

Song, Jieun; Mailick, Marsha R; Ryff, Carol D; Coe, Christopher L; Greenberg, Jan S; Hong, Jinkuk

2014-02-01

This study examines whether parents of children with developmental disorders are at risk of elevated allostatic load relative to control parents and whether positive affect moderates difference in risk. In all, 38 parents of children with developmental disorders and 38 matched comparison parents were analyzed. Regression analyses revealed a significant interaction between parent status and positive affect: parents of children with developmental disorders had lower allostatic load when they had higher positive affect, whereas no such association was evident for comparison parents. The findings suggest that promoting greater positive affect may lower health risks among parents of children with developmental disorders.

The role of social relationships in bipolar disorder: a review.

PubMed

Greenberg, Sarah; Rosenblum, Katherine L; McInnis, Melvin G; Muzik, Maria

2014-10-30

Social relationships and attachment are core developmental elements of human existence and survival that evolve over the lifetime of an individual. The internal and external factors that influence them include the presence of illness in the individual or in their immediate environment. The developmental aspects of attachment and social relationships have become increasingly of interest and relevance in light of early developmental epigenetic modification of gene expression patterns that may influence subsequent behavioral patterns and outcomes. This review examines extant literature on attachment and social relationships in bipolar cohorts. Despite many methodological challenges, the findings indicate that social relationships and capacity for attachment are significantly compromised in individuals with bipolar disorder compared to other mood disorders and normal controls. Though extant research is limited, research clearly points toward the importance of social relationships on the etiology, course, and consequences of bipolar disorder. We highlight a number of key considerations for future research. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Prologue: Toward Accurate Identification of Developmental Language Disorder Within Linguistically Diverse Schools.

PubMed

Oetting, Janna B

2018-04-05

Although the 5 studies presented within this clinical forum include children who differ widely in locality, language learning profile, and age, all were motivated by a desire to improve the accuracy at which developmental language disorder is identified within linguistically diverse schools. The purpose of this prologue is to introduce the readers to a conceptual framework that unites the studies while also highlighting the approaches and methods each research team is pursuing to improve assessment outcomes within their respective linguistically diverse community. A disorder within diversity framework is presented to replace previous difference vs. disorder approaches. Then, the 5 studies within the forum are reviewed by clinical question, type of tool(s), and analytical approach. Across studies of different linguistically diverse groups, research teams are seeking answers to similar questions about child language screening and diagnostic practices, using similar analytical approaches to answer their questions, and finding promising results with tools focused on morphosyntax. More studies that are modeled after or designed to extend those in this forum are needed to improve the accuracy at which developmental language disorder is identified.

Developmental language disorder (DLD, also called specific language impairment, SLI) is a common developmental disorder comprising the largest disability group in pre-school-aged children. Approximately 7% of the population is expected to have developmental language difficulties. However, the specific etiological factors leading to DLD are not yet known and even the typical linguistic features appear to vary by language. We present here a project that investigates DLD at multiple levels of analysis and aims to make the reliable prediction and early identification of the difficulties possible. Following the multiple deficit model of developmental disorders, we investigate the DLD phenomenon at the etiological, neural, cognitive, behavioral, and psychosocial levels, in a longitudinal study of preschool children. In January 2013, we launched the Helsinki Longitudinal SLI study (HelSLI) at the Helsinki University Hospital ( http://tiny.cc/HelSLI ). We will study 227 children aged 3-6 years with suspected DLD and their 160 typically developing peers. Five subprojects will determine how the child's psychological characteristics and environment correlate with DLD and how the child's well-being relates to DLD, the characteristics of DLD in monolingual versus bilingual children, nonlinguistic cognitive correlates of DLD, electrophysiological underpinnings of DLD, and the role of genetic risk factors. Methods include saliva samples, EEG, computerized cognitive tasks, neuropsychological and speech and language assessments, video-observations, and questionnaires. The project aims to increase our understanding of the multiple interactive risk and protective factors that affect the developing heterogeneous cognitive and behavioral profile of DLD, including factors affecting literacy development. This accumulated knowledge will form a heuristic basis for the development of new interventions targeting linguistic and non-linguistic aspects of DLD.

We investigated a consecutive series of children with chronic enterocolitis and regressive developmental disorder. 12 children (mean age 6 years [range 3-10], 11 boys) were referred to a paediatric gastroenterology unit with a history of normal development followed by loss of acquired skills, including language, together with diarrhoea and abdominal pain. Children underwent gastroenterological, neurological, and developmental assessment and review of developmental records. Ileocolonoscopy and biopsy sampling, magnetic-resonance imaging (MRI), electroencephalography (EEG), and lumbar puncture were done under sedation. Barium follow-through radiography was done where possible. Biochemical, haematological, and immunological profiles were examined. Onset of behavioural symptoms was associated, by the parents, with measles, mumps, and rubella vaccination in eight of the 12 children, with measles infection in one child, and otitis media in another. All 12 children had intestinal abnormalities, ranging from lymphoid nodular hyperplasia to aphthoid ulceration. Histology showed patchy chronic inflammation in the colon in 11 children and reactive ileal lymphoid hyperplasia in seven, but no granulomas. Behavioural disorders included autism (nine), disintegrative psychosis (one), and possible postviral or vaccinal encephalitis (two). There were no focal neurological abnormalities and MRI and EEG tests were normal. Abnormal laboratory results were significantly raised urinary methylmalonic acid compared with age-matched controls (p=0.003), low haemoglobin in four children, and a low serum IgA in four children. We identified associated gastrointestinal disease and developmental regression in a group of previously normal children, which was generally associated in time with possible environmental triggers.

Anxiety and Anxiety Disorders in Children and Adolescents: Developmental Issues and Implications for DSM-V

Beesdo, Katja; Knappe, Susanne; Pine, Daniel S.

2010-01-01

This review summarizes findings on the epidemiology and etiology of anxiety disorders among children and adolescents including separation anxiety disorder, specific phobia, social phobia, agoraphobia, panic disorder, and generalized anxiety disorder, also highlighting critical aspects of diagnosis, assessment, and treatment. Childhood and adolescence is the core risk phase for the development of anxiety symptoms and syndromes, ranging from transient mild symptoms to full-blown anxiety disorders. This article critically reviews epidemiological evidence covering prevalence, incidence, course, and risk factors. The core challenge in this age span is the derivation of developmentally more sensitive assessment methods. Identification of characteristics that could serve as solid predictors for onset, course, and outcome will require prospective designs that assess a wide range of putative vulnerability and risk factors. This type of information is important for improved early recognition and differential diagnosis as well as prevention and treatment in this age span. PMID:19716988

Cerebral creatine deficiencies: a group of treatable intellectual developmental disorders.

PubMed

Stockler-Ipsiroglu, Sylvia; van Karnebeek, Clara D M

2014-07-01

Currently there are 91 treatable inborn errors of metabolism that cause intellectual developmental disorders. Cerebral creatine deficiencies (CDD) comprise three of these: arginine: glycine amidinotransferase [AGAT], guanidinoacetate methyltransferase [GAMT], and X-linked creatine transporter deficiency [SLC6A8]. Intellectual developmental disorder and cerebral creatine deficiency are the hallmarks of CDD. Additional clinical features include prominent speech delay, autism, epilepsy, extrapyramidal movement disorders, and signal changes in the globus pallidus. Patients with GAMT deficiency exhibit the most severe clinical spectrum. Myopathy is a distinct feature in AGAT deficiency. Guanidinoacetate (GAA) is the immediate product in the creatine biosynthetic pathway. Low GAA concentrations in urine, plasma, and cerebrospinal fluid are characteristic diagnostic markers for AGAT deficiency, while high GAA concentrations are characteristic markers for GAMT deficiency. An elevated ratio of urinary creatine /creatinine excretion serves as a diagnostic marker in males with SLC6A8 deficiency. Treatment strategies include oral supplementation of high-dose creatine-monohydrate for all three CDD. Guanidinoacetate-reducing strategies (high-dose ornithine, arginine-restricted diet) are additionally employed in GAMT deficiency. Supplementation of substrates for intracerebral creatine synthesis (arginine, glycine) has been used additionally to treat SLC6A8 deficiency. Early recognition and treatment improves outcomes. Normal outcomes in neonatally ascertained siblings from index families with AGAT and GAMT deficiency suggest a potential benefit of newborn screening for these disorders.

To investigate the link between autism disorders and engineering training of parents. All Autistic-Pervasive Developmental Disorders (PDD) children that were diagnosed on the bases of the Diagnostic and Statistical Manual for Mental Disorders (DSM-IV), and met the required criteria for autism, over a defined period (March 2006 to June 2007) were included. We then took all non-PDD developmental disorders cases seen during the same time frame as the autistic children as a control; these included speech delay, mental retardation, and Down's syndrome. Our data covered demographic data, parents and grandparents' education, and profession. Parents' education/professions were classified into 2 groups only, 1-engineering or mathematician; and 2-humanities, neither engineering nor math. The children were divided into 2 groups, autism (57 cases), and developmental disorders (40 cases). Regarding the main question of this study (hypothesized engineering link), the data showed some differences between the 2 groups (x2 = 2.503, degrees of freedom [df] = 1; p = 0.093), but not of major significance. There was no significant difference (x2 = 0.370; df = 2; p = 0.831) between the 2 groups on the variable of consanguinity. We have found that the Saudi Arabian sample, though relatively small, has considerable similarities with both the UK and USA data. There is a possibility of an association between autism and the engineering/math training of fathers. The implication is briefly discussed.

The aim of this study was to subtype groups of children in a community sample with and without developmental conditions, based on sensory processing patterns. We used latent profile analysis to determine the number of sensory subtypes in a sample of n = 1132 children aged 3-14 years with typical development and developmental conditions, including autism spectrum disorder (ASD), attention-deficit hyperactivity disorder and learning disabilities. A five-subtype solution was found to best characterize the sample, which differed on overall degree and differential presentation of sensory processing patterns. Children with and without developmental conditions presented across subtypes, and one subtype was significantly younger in age than others (P < 0.05). Our results show that sensory subtypes include both children with typical development and those with developmental conditions. Sensory subtypes have previously been investigated in ASD only, and our results suggest that similar sensory subtypes are present in a sample reflective of the general population of children including those largely with typical development. Elevated scores on sensory processing patterns are not unique to ASD but rather are reflections of children's abilities to respond to environmental demands. © 2016 John Wiley & Sons Ltd.

Developmental pathways to autism: A review of prospective studies of infants at risk☆

2014-01-01

Autism Spectrum Disorders (ASDs) are neurodevelopmental disorders characterized by impairments in social interaction and communication, and the presence of restrictive and repetitive behaviors. Symptoms of ASD likely emerge from a complex interaction between pre-existing neurodevelopmental vulnerabilities and the child's environment, modified by compensatory skills and protective factors. Prospective studies of infants at high familial risk for ASD (who have an older sibling with a diagnosis) are beginning to characterize these developmental pathways to the emergence of clinical symptoms. Here, we review the range of behavioral and neurocognitive markers for later ASD that have been identified in high-risk infants in the first years of life. We discuss theoretical implications of emerging patterns, and identify key directions for future work, including potential resolutions to several methodological challenges for the field. Mapping how ASD unfolds from birth is critical to our understanding of the developmental mechanisms underlying this disorder. A more nuanced understanding of developmental pathways to ASD will help us not only to identify children who need early intervention, but also to improve the range of interventions available to them.

Pediatric populations, including those with autistic disorder or other pervasive developmental disorders, increasingly are being prescribed selective serotonin reuptake inhibitors (SSRIs). Little is known about the age-related brain pharmacokinetics of SSRIs; there is a lack of data regarding optimal dosing of medications for children. The authors used fluorine magnetic resonance spectroscopy ((19)F MRS) to evaluate age effects on whole-brain concentrations of fluvoxamine and fluoxetine in children taking SSRIs. Twenty-one pediatric subjects with diagnoses of autistic disorder or other pervasive developmental disorders, 6-15 years old and stabilized with a consistent dose of fluvoxamine or fluoxetine, were recruited for the study; 16 successfully completed the imaging protocol. Whole-brain drug levels in this group were compared to similarly acquired data from 28 adults. A significant relationship between dose and brain drug concentration was observed for both drugs across the age range studied. Brain fluvoxamine concentration in the children was lower, consistent with a lower dose/body mass drug prescription; when brain concentration was adjusted for dose/mass, age effects were no longer significant. Brain fluoxetine concentration was similar between age groups; no significant age effects on brain fluoxetine drug levels remained after adjustment for dose/mass. Observations of brain fluoxetine bioavailability and elimination half-life also were similar between age groups. These findings suggest that fluvoxamine or fluoxetine prescriptions adjusted for dose/mass are an acceptable treatment approach for medicating children with autistic disorder or other pervasive developmental disorders. It must be determined whether these findings can be generalized to other pediatric populations.

Designing affective video games to support the social-emotional development of teenagers with autism spectrum disorders.

PubMed

Khandaker, Mitu

2009-01-01

Autism spectrum disorders (ASD) are a group of developmental neuropsychiatric disorders, comprised of three diagnostic entities - autistic disorder (AD), Asperger's disorder (AS), and Pervasive Developmental Disorder Not Otherwise Specified (including atypical autism) (PDD-NOS). A number of intervention techniques are currently used to reduce some of the associated challenges, with techniques ranging from behavioral therapy to dietary interventions and traditional counseling. This positional paper proposes the use of video games which leverage affective computing technologies as intervention in autism spectrum disorders in the context of the use of traditional play therapy with adolescents, who may feel uncomfortable engaging in traditional play with toys they may be too old for. It aims to explore the potential for greater 'social physics' made possible by affective computing technologies. This involves computationally 'recognizing' emotions in a user, often through the use of multimodal affective sensors, including facial expressions, postural shifts, and physiological signals such as heart rate, skin conductivity, and EEG signals. However, it is suggested that this should be augmented by researching the effect of social game design mechanisms on social-emotional development, particularly for those who experience difficulty with social interaction.

Maternal exposure to the holocaust and health complaints in offspring.

Flory, Janine D; Bierer, Linda M; Yehuda, Rachel

2011-01-01

Although the link between chronic stress and the development of cardiovascular and metabolic diseases of adulthood has been known for some time, there is growing recognition that early environmental influences may result in developmental programming via epigenetic mechanisms, thereby affecting the developmental trajectory of disease progression. Previous studies support the idea that offspring of Holocaust survivors may have been subjected to early developmental programming. We evaluated the relationship between parental exposure to the Holocaust and self-reported health ratings and disorders made by their adult offspring (i.e., second generation Holocaust survivors). A total of 137 subjects were evaluated. Regression analyses demonstrated that maternal but not paternal exposure to the Holocaust was related to poorer subjective impressions of emotional and physical health. This relationship was diminished when the offspring's own level of trait anxiety was considered. Offspring with maternal, but not paternal, Holocaust exposure also reported greater use of psychotropic and other medications, including medications for the treatment of hypertension and lipid disorders. The mechanism linking these health outcomes and maternal exposure deserves further investigation, including the possibility that fetal or early developmental programming is involved.

Difference or disorder? Cultural issues in understanding neurodevelopmental disorders.

PubMed

Norbury, Courtenay Frazier; Sparks, Alison

2013-01-01

Developmental disorders, such as autism spectrum disorder and specific language impairment, are biologically based disorders that currently rely on behaviorally defined criteria for diagnosis and treatment. Specific behaviors that are included in diagnostic frameworks and the point at which individual differences in behavior constitute abnormality are largely arbitrary decisions. Such decisions are therefore likely to be strongly influenced by cultural values and expectations. This is evident in the dramatically different prevalence rates of autism spectrum disorder across countries and across different ethnic groups within the same country. In this article, we critically evaluate the understanding of developmental disorders from a cultural perspective. We specifically consider the challenges of applying diagnostic methods across cultural contexts, the influence of cultural values and expectations on the identification and treatment of children with suspected disorders, and how cross-cultural studies can help to refine cognitive theories of disorder that have been derived exclusively from Western North American and European investigations. Our review synthesizes clinical, cultural, and theoretical work in this area, highlighting potential universals of disorder and concluding with recommendations for future research and practice.

Sexually Dimorphic Responses to Early Adversity: Implications for Affective Problems and Autism Spectrum Disorder

PubMed Central

Davis, Elysia Poggi; Pfaff, Donald

2014-01-01

During gestation, development proceeds at a pace that is unmatched by any other stage of the lifecycle. For these reason the human fetus is particularly susceptible not only to organizing influences, but also to pathogenic disorganizing influences. Growing evidence suggests that exposure to prenatal adversity leads to neurological changes that underlie lifetime risks for mental illness. Beginning early in gestation, males and females show differential developmental trajectories and responses to stress. It is likely that sex-dependent organization of neural circuits during the fetal period influences differential vulnerability to mental health problems. We consider in this review evidence that sexually dimorphic responses to early life stress are linked to two developmental disorders: affective problems (greater female prevalence) and autism spectrum disorder (greater male prevalence). Recent prospective studies illustrating the neurodevelopmental consequences of fetal exposure to stress and stress hormones for males and females are considered here. Plausible biological mechanisms including the role of the sexually differentiated placenta are discussed. We consider in this review evidence that sexually dimorphic responses to early life stress are linked to two sets of developmental disorders: affective problems (greater female prevalence) and autism spectrum disorders (greater male prevalence).

Studies with outcomes in favour of neurofeedback might be showing an improvement in comorbid attention-deficit-hyperactivity disorder symptoms rather than a true improvement in core ASD symptoms. Limitations of this review are those inherent in the studies available, including small sample size, short duration, variable diagnostic criteria, and insufficient control interventions, all causing a lack of generalizability. © The Authors.

Developmental and benign movement disorders are a group of movement disorders with onset in the neonatal period, infancy, or childhood. They are characterized by the absence of associated neurological manifestations and by their favorable outcome, although developmental abnormalities can be occasionally observed. Knowledge of the clinical, neurophysiological, and pathogenetic aspects of these disorders is poor. Based on a comprehensive review of the literature and our practical experience, this article summarizes current knowledge in this area. We pay special attention to the recognition and management of these movement disorders in children. (c) 2010 Movement Disorder Society.

Autism Spectrum Disorder Updates - Relevant Information for Early Interventionists to Consider.

PubMed

Allen-Meares, Paula; MacDonald, Megan; McGee, Kristin

2016-01-01

Autism spectrum disorder (ASD) is a pervasive developmental disorder characterized by deficits in social communication skills as well as repetitive, restricted or stereotyped behaviors (1). Early interventionists are often found at the forefront of assessment, evaluation, and early intervention services for children with ASD. The role of an early intervention specialist may include assessing developmental history, providing group and individual counseling, working in partnership with families on home, school, and community environments, mobilizing school and community resources, and assisting in the development of positive early intervention strategies (2, 3). The commonality among these roles resides in the importance of providing up-to-date, relevant information to families and children. The purpose of this review is to provide pertinent up-to-date knowledge for early interventionists to help inform practice in working with individuals with ASD, including common behavioral models of intervention.

Previous research has shown important developmental shifts ingenetic and environmental influences for disordered eating. However, little research has examined age differences for weight/shape concerns, two key components of eating disorders. The goal of this study was to investigate these age differences in preadolescent, adolescent, young adult, and mid-adult twins. Participants included 2,618 female twins (ages of 10-41 years) from three large twin registries. Shape and weight concerns were assessed with the Eating Disorders Examination Questionnaire. Genetic influences were modest in preadolescent twins, but significant from early-adolescence through middle adulthood. Shared environmental factors showed the opposite pattern, with the largest shared environmental contributions occurring in the youngest age group. Nonshared environmental effects remained relatively constant across age. Findings highlight the importance of age differences in genetic and environmental influences. Possible mechanisms include gene x environment interactions and biological changes associated with key developmental stages. © 2009 by Wiley Periodicals, Inc.

Yuen, Kevin C P

2014-01-01

One of the recent developments in the education of speech-language pathology is to include literacy disorders and learning disabilities as key training components in the training curriculum. Disorders in reading and writing are interwoven with disorders in speaking and listening, which should be managed holistically, particularly in children and adolescents. With extensive training in clinical linguistics, language disorders, and other theoretical knowledge and clinical skills, speech-language pathologists (SLPs) are the best equipped and most competent professionals to screen, identify, diagnose, and manage individuals with literacy disorders. To tackle the challenges of and the huge demand for services in literacy as well as language and learning disorders, the Hong Kong Institute of Education has recently developed the Master of Science Programme in Educational Speech-Language Pathology and Learning Disabilities, which is one of the very first speech-language pathology training programmes in Asia to blend training components of learning disabilities, literacy disorders, and social-emotional-behavioural-developmental disabilities into a developmentally and medically oriented speech-language pathology training programme. This new training programme aims to prepare a new generation of SLPs to be able to offer comprehensive support to individuals with speech, language, literacy, learning, communication, and swallowing disorders of different developmental or neurogenic origins, particularly to infants and adolescents as well as to their family and educational team. © 2015 S.

To describe the last 5 years' experience of Child Development Centre (CDC), Kerala Developmental Evaluation Clinic II for children between 2 and 10 y, referred for suspicion of developmental lag in the preschool years and scholastic difficulty in the primary classes with specific focus on developmental profile and the experience of the home based intervention package taught to the mothers. A team of evaluators including developmental therapist, preschool teacher with special training in clinical child development, speech therapist, special educator, clinical psychologist and developmental pediatrician assessed all the children referred to CDC Kerala. Denver Developmental Screening Test (DDST-II), Vineland Social Maturity Scale (VSMS) and Intelligent Quotient (IQ) tests were administered to all children below 6 y and those above 6 with apparent developmental delay. Speech/delay (35.9%), behavior problem (15.4%), global delay/ intellectual disability (15.4%), learning problem (10.9%), pervasive developmental disorders (7.7%), seizure disorder (1.7%), hearing impairment (0.7%), and visual impairment (0.7%) were the clinical diagnosis by a developmental pediatrician. Each child with developmental problem was offered a home based intervention package consisting of developmental therapy and special education items, appropriate to the clinical diagnosis of the individual child and the same was taught to the mother. The experience of conducting the developmental evaluation clinic for children between 2 and 10 y has shown that a team consisting of developmental therapist, speech therapist, preschool teacher, special educator, clinical child psychologist and developmental pediatrician, using appropriate test results of the child could make a clinical diagnosis good enough for providing early intervention therapy using a home based intervention package.

Understanding the perspectives of caregivers of children with developmental disorders living in low-income countries is important to inform intervention programmes. The purpose of this study was to examine the stigma experiences, explanatory models, unmet needs, preferred interventions and coping mechanisms of caregivers of children with developmental disorders in Ethiopia. Participants comprised caregivers (n = 102) of children with developmental disorders attending two child mental health clinics in Addis Ababa. The majority (66.7%; n = 68) had a diagnosis of intellectual disability (ID); 34 children (33.3%) had autism spectrum disorder (ASD) as their primary diagnosis. All caregivers were administered a structured questionnaire via a face-to-face interview, which included an adaptation of the Family Interview Schedule, closed questions about socio-demographic characteristics, explanatory models of illness, type of interventions used or desired and coping strategies, and an open ended question regarding the family's unmet needs. Most caregivers reported experience of stigma: 43.1% worried about being treated differently, 45.1% felt ashamed about their child's condition and 26.7% made an effort to keep their child's condition secret. Stigma did not depend on the type of developmental disorder, the child's age or gender, or on the age or level of education of the caregiver (all p > 0.05). Reported stigma was significantly higher in caregivers who had sought traditional help (p < 0.01), provided supernatural explanations for their child's condition (p = .02) and in caregivers of Orthodox Christian faith (p = .03). Caregivers gave a mixture of biomedical explanations (e.g. head injury (30.4%) or birth complications (25.5%)) and supernatural explanations (e.g. spirit possession (40.2%) or sinful act (27.5%)) for their child's condition. The biggest reported unmet need was educational provision for their child (74.5%), followed by treatment by a health professional (47.1%), financial support (30.4%) and expert help to support their child's development (27.5%). Most caregivers reported that talking to health professionals (86.3%) and family (85.3%) helped them to cope. Many caregivers also used support from friends (76.5%) and prayer (57.8%) as coping mechanisms. This study highlights the stigma experienced by families caring for a child with a developmental disorder. Designing interventions appropriate for low-income settings that improve awareness about developmental disorders, decrease stigma, improve access to appropriate education and strengthen caregivers' support are needed.

Interstitial deletions of the long arm of chromosome 6 are rare, and most reported cases represent large, cytogenetically detectable deletions. The implementation of array comparative genome hybridisation in the diagnostic work-up of patients presenting with congenital disorders, including developmental delay, has enabled identification of many patients with smaller chromosomal imbalances. In this report, the cases are presented of four patients with a de novo interstitial deletion of chromosome 6q13-14, resulting in a common microdeletion of 3.7 Mb. All presented with developmental delay, mild dysmorphism and signs of lax connective tissue. Interestingly, the common deleted region harbours 16 genes, of which COL12A1 is a good candidate for the connective tissue pathology.

2017-06-01

Autism Spectrum Disorder (ASD) and Developmental Coordination Disorder (DCD) are developmental disorders that, since the DSM-5, can be diagnosed as co-occurring conditions. While some recent studies suggest that ASD and DCD have similar traits, others show clear behavioral distinctions between the two conditions. By gathering all studies that included (1) an ASD group and a DCD group, (2) an ASD+DCD group and a DCD group, or (3) ASD, ASD+DCD, and DCD groups, we aimed to identify similarities and differences in behaviors between the two disorders. We used a systematic search of PubMed (1946 -), Scopus (1970 -), PsycINFO (via EBSCO, 1600 -), CINAHL (via EBSCO, 1937 -), SportDiscus (via EBSCO, 1985 -), and WorldCat (via FirstSearch) in addition to reference list and author name searching PubMed, Scopus, PsycINFO, CINAHL, SportDiscus, and WorldCat to identify original studies that met the following criteria: (1) an ASD group and a DCD group, (2) an ASD+DCD group and a DCD group, or (3) ASD, ASD+DCD, and DCD groups. From the 1,598 articles screened, 11 were included in the qualitative analysis. The articles included reported more differences than similarities in individuals with ASD and DCD, with clear distinctions for working memory ability, gestural performance, grip selection, and cortical thickness. Only two studies reported similarities in face processing abilities and perceived competence, and the interventional studies showed group similarities in behavior improvement, such as intelligence and attention. Based on the articles reviewed, we conclude that while DCD and ASD share some behavioral symptoms, the symptom profiles of each disorder are unique and separable. We recommend that the evaluation of potential DCD in individuals with ASD be performed systematically and thoroughly, so as to distinguish this co-occurring condition from sensorimotor symptoms associated with ASD.

Quality Group Home Care for Adults with Developmental Disabilities and/or Mental Health Disorders: Yearning for Understanding, Security and Freedom.

2017-09-01

The purpose of this study was to uncover and understand factors influencing quality of care received by adults with developmental disabilities and/or mental health disorders living in group homes. The present authors conducted a secondary analysis of data from nine focus group discussions with adults with developmental disabilities and/or mental health disorders, and their family and paid caregivers (N = 52). To focus the analysis, the present authors drew on the research literature to craft a model of quality of group home care using concepts of social inclusion and self-determination, and corresponding staff approaches that include active support and person-centred care. Social inclusion and self-determination for adults in group homes are facilitated by staff approaches and manifest in residents being understood and experiencing security and freedom. The present authors offer recommendations for group home resources, training, communication and outcome measures that promote residents' being understood and experiencing security and freedom. © 2016 John Wiley & Sons Ltd.

2004-02-01

Autistic spectrum disorders (ASD) is a term that is not included in DSM IV or in ICD 10, which are the diagnostic tools most commonly used by clinical professionals but can offer problems in research when it comes to finding homogenous groups. From a neuropaediatric point of view, there is a need for a classification of the generalised disorders affecting development and for this purpose we used Wing's triad, which defines the continuum of the autistic spectrum, and the information provided by magnetoencephalography (MEG) as grouping elements. Specific generalised developmental disorders were taken as being those syndromes that partially expressed some autistic trait, but with their own personality so that they could be considered to be a specific disorder. ASD were classified as being primary, cryptogenic or secondary. The primary disorders, in turn, express a continuum that ranges from Savant syndrome to Asperger's syndrome and the different degrees of early infantile autism. MEG is a functional neuroimaging technique that has enabled us to back up this classification.

Histone lysine methyltransferases (KMTs) and demethylases (KDMs) underpin gene regulation. Here we demonstrate that variants causing haploinsufficiency of KMTs and KDMs are frequently encountered in individuals with developmental disorders. Using a combination of human variation databases and existing animal models, we determine 22 KMTs and KDMs as additional candidates for dominantly inherited developmental disorders. We show that KMTs and KDMs that are associated with, or are candidates for, dominant developmental disorders tend to have a higher level of transcription, longer canonical transcripts, more interactors, and a higher number and more types of post-translational modifications than other KMT and KDMs. We provide evidence to firmly associate KMT2C, ASH1L, and KMT5B haploinsufficiency with dominant developmental disorders. Whereas KMT2C or ASH1L haploinsufficiency results in a predominantly neurodevelopmental phenotype with occasional physical anomalies, KMT5B mutations cause an overgrowth syndrome with intellectual disability. We further expand the phenotypic spectrum of KMT2B-related disorders and show that some individuals can have severe developmental delay without dystonia at least until mid-childhood. Additionally, we describe a recessive histone lysine-methylation defect caused by homozygous or compound heterozygous KDM5B variants and resulting in a recognizable syndrome with developmental delay, facial dysmorphism, and camptodactyly. Collectively, these results emphasize the significance of histone lysine methylation in normal human development and the importance of this process in human developmental disorders. Our results demonstrate that systematic clinically oriented pathway-based analysis of genomic data can accelerate the discovery of rare genetic disorders.

Newman, Michelle G.; Shin, Ki Eun; Zuellig, Andrea R.

2016-01-01

Background There is a lack of clarity regarding specific risk factors discriminating generalized anxiety disorder (GAD) from panic disorder (PD). Goal This study investigated whether GAD and PD could be discriminated through differences in developmental etiological factors including childhood parental loss/separation, psychological disorders, and maternal and paternal attachment. Method Twenty people with adult generalized anxiety disorder (GAD), 20 with adult panic disorder (PD), 11 with adult comorbid GAD and PD, and 21 adult non-anxious controls completed diagnostic interviews to assess symptoms of mental disorders in adulthood and childhood. Participants also reported on parental attachment, loss, and separation. Results Childhood diagnoses of GAD and PD differentiated clinical groups from controls as well as from each other, suggesting greater likelihood for homotypic over heterotypic continuity. Compared to controls, specific phobia was associated with all three clinical groups, and childhood depression, social phobia, and PTSD were uniquely associated with adult GAD. Both maternal and paternal attachment also differentiated clinical groups from controls. However, higher levels of subscales reflecting maternal insecure avoidant attachment (e.g., no memory of early childhood experiences and balancing/forgiving current state of mind) emerged as more predictive of GAD relative to PD. There were no group differences in parental loss or separation. Conclusions These results support differentiation of GAD and PD based on developmental risk factors. Recommendations for future research and implications of the findings for understanding the etiology and symptomatology of GAD and PD are discussed. PMID:27466747

Developmental disorders: what can be learned from cognitive neuropsychology?

Castles, Anne; Kohnen, Saskia; Nickels, Lyndsey; Brock, Jon

2014-01-01

The discipline of cognitive neuropsychology has been important for informing theories of cognition and describing the nature of acquired cognitive disorders, but its applicability in a developmental context has been questioned. Here, we revisit this issue, asking whether the cognitive neuropsychological approach can be helpful for exploring the nature and causes of developmental disorders and, if so, how. We outline the key features of the cognitive neuropsychological approach, and then consider how some of the major challenges to this approach from a developmental perspective might be met. In doing so, we distinguish between challenges to the methods of cognitive neuropsychology and those facing its deeper conceptual underpinnings. We conclude that the detailed investigation of patterns of both associations and dissociations, and across both developmental and acquired cases, can assist in describing the cognitive deficits within developmental disorders and in delineating possible causal pathways to their acquisition.

Developmental disorders (DD) are now so common that it is even more necessary to investigate the relationship between DD and personality disorders (PD). Despite the lack of studies, DD and PD have much in common. For research on personality and its disorders, direct, real-time observation by researchers themselves on the "black box" of temperament and its interaction with the environment is needed. For research on DD, especially in those with mild DD symptoms, how developmental characteristics and their interaction with the environment affect the personality in adulthood should be investigated.

Recent studies have shown that certain copy number variations (CNV) are associated with a wide range of neurodevelopmental disorders, including autism spectrum disorders (ASD), bipolar disorder and intellectual disabilities. Implicated regions and genes have comprised a variety of post synaptic complex proteins and neurotransmitter receptors, including gamma-amino butyric acid A (GABAA). Clusters of GABAA receptor subunit genes are found on chromosomes 4p12, 5q34, 6q15 and 15q11-13. Maternally inherited 15q11-13 duplications among individuals with neurodevelopmental disorders are well described, but few case reports exist for the other regions. We describe a family with a 2.42 Mb duplication at chromosome 4p13 to 4p12, identified in the index case and other family members by oligonucleotide array comparative genomic hybridization, that contains 13 genes including a cluster of four GABAA receptor subunit genes. Fluorescent in-situ hybridization was used to confirm the duplication. The duplication segregates with a variety of neurodevelopmental disorders in this family, including ASD (index case), developmental delay, dyspraxia and ADHD (brother), global developmental delays (brother), learning disabilities (mother) and bipolar disorder (maternal grandmother). In addition, we identified and describe another individual unrelated to this family, with a similar duplication, who was diagnosed with ASD, ADHD and borderline intellectual disability. The 4p13 to 4p12 duplication appears to confer a susceptibility to a variety of neurodevelopmental disorders in these two families. We hypothesize that the duplication acts through a dosage effect of GABAA receptor subunit genes, adding evidence for alterations in the GABAergic system in the etiology of neurodevelopmental disorders.

Developmental programming by androgen affects the circadian timing system in female mice.

Mereness, Amanda L; Murphy, Zachary C; Sellix, Michael T

2015-04-01

Circadian clocks play essential roles in the timing of events in the mammalian hypothalamo-pituitary-ovarian (HPO) axis. The molecular oscillator driving these rhythms has been localized to tissues of the HPO axis. It has been suggested that synchrony among these oscillators is a feature of normal reproductive function. The impact of fertility disorders on clock function and the role of the clock in the etiology of endocrine pathology remain unknown. Polycystic ovarian syndrome (PCOS) is a particularly devastating fertility disorder, affecting 5%-10% of women at childbearing age with features including a polycystic ovary, anovulation, and elevated serum androgen. Approximately 40% of these women have metabolic syndrome, marked by hyperinsulinemia, dyslipidemia, and insulin resistance. It has been suggested that developmental exposure to excess androgen contributes to the etiology of fertility disorders, including PCOS. To better define the role of the timing system in these disorders, we determined the effects of androgen-dependent developmental programming on clock gene expression in tissues of the metabolic and HPO axes. Female PERIOD2::luciferase (PER2::LUC) mice were exposed to androgen (dihydrotestosterone [DHT]) in utero (Days 16-18 of gestation) or for 9-10 wk (DHT pellet) beginning at weaning (pubertal androgen excess [PAE]). As expected, both groups of androgen-treated mice had disrupted estrous cycles. Analysis of PER2::LUC expression in tissue explants revealed that excess androgen produced circadian misalignment via tissue-dependent effects on phase distribution. In vitro treatment with DHT differentially affected the period of PER2::LUC expression in tissue explants and granulosa cells, indicating that androgen has direct and tissue-specific effects on clock gene expression that may account for the effects of developmental programming on the timing system. © 2015 by the Society for the Study of Reproduction, Inc.

Classification of feeding and eating disorders: review of evidence and proposals for ICD-11

PubMed Central

UHER, RUDOLF; RUTTER, MICHAEL

2012-01-01

Current classification of eating disorders is failing to classify most clinical presentations; ignores continuities between child, adolescent and adult manifestations; and requires frequent changes of diagnosis to accommodate the natural course of these disorders. The classification is divorced from clinical practice, and investigators of clinical trials have felt compelled to introduce unsystematic modifications. Classification of feeding and eating disorders in ICD-11 requires substantial changes to remediate the shortcomings. We review evidence on the developmental and cross-cultural differences and continuities, course and distinctive features of feeding and eating disorders. We make the following recommendations: a) feeding and eating disorders should be merged into a single grouping with categories applicable across age groups; b) the category of anorexia nervosa should be broadened through dropping the requirement for amenorrhoea, extending the weight criterion to any significant underweight, and extending the cognitive criterion to include developmentally and culturally relevant presentations; c) a severity qualifier “with dangerously low body weight” should distinguish the severe cases of anorexia nervosa that carry the riskiest prognosis; d) bulimia nervosa should be extended to include subjective binge eating; e) binge eating disorder should be included as a specific category defined by subjective or objective binge eating in the absence of regular compensatory behaviour; f) combined eating disorder should classify subjects who sequentially or concurrently fulfil criteria for both anorexia and bulimia nervosa; g) avoidant/restrictive food intake disorder should classify restricted food intake in children or adults that is not accompanied by body weight and shape related psychopathology; h) a uniform minimum duration criterion of four weeks should apply.

The WARM study is a longitudinal cohort study following infants of mothers with schizophrenia, bipolar disorder, depression and control from pregnancy to infant 1 year of age. Children of parents diagnosed with complex mental health problems including schizophrenia, bipolar disorder and depression, are at increased risk of developing mental health problems compared to the general population. Little is known regarding the early developmental trajectories of infants who are at ultra-high risk and in particular the balance of risk and protective factors expressed in the quality of early caregiver-interaction. We are establishing a cohort of pregnant women with a lifetime diagnosis of schizophrenia, bipolar disorder, major depressive disorder and a non-psychiatric control group. Factors in the parents, the infant and the social environment will be evaluated at 1, 4, 16 and 52 weeks in terms of evolution of very early indicators of developmental risk and resilience focusing on three possible environmental transmission mechanisms: stress, maternal caregiver representation, and caregiver-infant interaction. The study will provide data on very early risk developmental status and associated psychosocial risk factors, which will be important for developing targeted preventive interventions for infants of parents with severe mental disorder.

2013-01-01

Background The development of effective treatments for use by non-specialists is listed among the top research priorities for improving the lives of people with mental illness worldwide. The purpose of this review is to appraise which interventions for children with intellectual disabilities or lower-functioning autism spectrum disorders delivered by non-specialist care providers in community settings produce benefits when compared to either a no-treatment control group or treatment-as-usual comparator. Methods and Findings We systematically searched electronic databases through 24 June 2013 to locate prospective controlled studies of psychosocial interventions delivered by non-specialist providers to children with intellectual disabilities or lower-functioning autism spectrum disorders. We screened 234 full papers, of which 34 articles describing 29 studies involving 1,305 participants were included. A majority of the studies included children exclusively with a diagnosis of lower-functioning autism spectrum disorders (15 of 29, 52%). Fifteen of twenty-nine studies (52%) were randomized controlled trials and just under half of all effect sizes (29 of 59, 49%) were greater than 0.50, of which 18 (62%) were statistically significant. For behavior analytic interventions, the best outcomes were shown for development and daily skills; cognitive rehabilitation, training, and support interventions were found to be most effective for improving developmental outcomes, and parent training interventions to be most effective for improving developmental, behavioral, and family outcomes. We also conducted additional subgroup analyses using harvest plots. Limitations include the studies' potential for performance bias and that few were conducted in lower- and middle-income countries. Conclusions The findings of this review support the delivery of psychosocial interventions by non-specialist providers to children who have intellectual disabilities or lower-functioning autism spectrum disorders. Given the scarcity of specialists in many low-resource settings, including many lower- and middle-income countries, these findings may provide guidance for scale-up efforts for improving outcomes for children with developmental disorders or lower-functioning autism spectrum disorders.

Micro-RNAs and their roles in eye disorders.

PubMed

Raghunath, Azhwar; Perumal, Ekambaram

2015-01-01

Micro-RNAs (miRNAs) are members of the family of noncoding RNA molecules that regulate gene expression by translational repression and mRNA degradation. Initial identification of miRNAs revealed them only as developmental regulators; later, their radiated roles in various cellular processes have been established. They regulate several pathways, including developmental timing, hematopoiesis, organogenesis, apoptosis, cell differentiation and proliferation. Their roles in eye disorders are being explored by biologists around the world. Eye physiology requires the perfect orchestration of all the regulatory networks; any defect in any of the networks leads to eye disorders. The dysregulation of miRNA expression has been reported in many eye disorders, which paves the way for new therapeutics. This review summarizes the biogenesis of miRNAs and their role in eye disorders. miRNA studies also have implications for the understanding of various complex metabolic pathways leading to disorders of the eye. The ultimate understanding leads to potential opportunities in evaluating miRNAs as molecular biomarkers, prognostic tools, diagnostic tools and therapeutic agents for eye disorders. © 2015 S.

Noonan syndrome and clinically related disorders

PubMed Central

Tartaglia, Marco; Gelb, Bruce D.; Zenker, Martin

2010-01-01

Noonan syndrome is a relatively common, clinically variable developmental disorder. Cardinal features include postnatally reduced growth, distinctive facial dysmorphism, congenital heart defects and hypertrophic cardiomyopathy, variable cognitive deficit and skeletal, ectodermal and hematologic anomalies. Noonan syndrome is transmitted as an autosomal dominant trait, and is genetically heterogeneous. So far, heterozygous mutations in nine genes (PTPN11, SOS1, KRAS, NRAS, RAF1, BRAF, SHOC2, MEK1 and CBL) have been documented to underlie this disorder or clinically related phenotypes. Based on these recent discoveries, the diagnosis can now be confirmed molecularly in approximately 75% of affected individuals. Affected genes encode for proteins participating in the RAS-mitogen-activated protein kinases (MAPK) signal transduction pathway, which is implicated in several developmental processes controlling morphology determination, organogenesis, synaptic plasticity and growth. Here, we provide an overview of clinical aspects of this disorder and closely related conditions, the molecular mechanisms underlying pathogenesis, and major genotype-phenotype correlations.

2011-01-01

Estimations of time and number share many similarities in both non-humans and man. The primary focus of this review is on the development of time and number sense across infancy and childhood, and neuropsychological findings as they relate to time and number discrimination in infants and adults. Discussion of these findings is couched within a mode-control model of timing and counting which assumes time and number share a common magnitude representation system. A basic sense of time and number likely serves as the foundation for advanced numerical and temporal competence, and aspects of higher cognition—this will be discussed as it relates to typical childhood, and certain developmental disorders, including autism spectrum disorder. Directions for future research in the developmental neuroscience of time and number (NEUTIN) will also be highlighted. PMID:22408612

2016-08-01

Function of epigenetic modifications is one of the most competitive fields in life science. Over the past several decades, it has been revealed that epigenetic modifications play essential roles in development and diseases including developmental diseases. In the present review, we summarize the recent progress about the function of epigenetic regulation, especially DNA and RNA modifications in developmental diseases. Original research articles and literature reviews published in PubMed-indexed journals. DNA modifications including methylation and demethylation can regulate gene expression, and are involved in development and multiple diseases including Rett syndrome, Autism spectrum disorders, congenital heart disease and cancer, etc. RNA methylation and demethylation play important roles in RNA processing, reprogramming, circadian, and neuronal activity, and then modulate development. DNA and RNA modifications play important roles in development and diseases through regulating gene expression. Epigenetic components could serve as novel targets for the treatment of developmental diseases.

Development disorders and delays are recognised as a public health priority and included in the WHO mental health gap action programme (mhGAP). Parents Skills Training (PST) is recommended as a key intervention for such conditions under the WHO mhGAP intervention guide. However, sustainable and scalable delivery of such evidence based interventions remains a challenge. This study aims to evaluate the effectiveness and scaled-up implementation of locally adapted WHO PST programme delivered by family volunteers in rural Pakistan. The study is a two arm single-blind effectiveness implementation-hybrid cluster randomised controlled trial. WHO PST programme will be delivered by 'family volunteers' to the caregivers of children with developmental disorders and delays in community-based settings. The intervention consists of the WHO PST along with the WHO mhGAP intervention for developmental disorders adapted for delivery using the android application on a tablet device. A total of 540 parent-child dyads will be recruited from 30 clusters. The primary outcome is child's functioning, measured by WHO Disability Assessment Schedule - child version (WHODAS-Child) at 6 months post intervention. Secondary outcomes include children's social communication and joint engagement with their caregiver, social emotional well-being, parental health related quality of life, family empowerment and stigmatizing experiences. Mixed method will be used to collect data on implementation outcomes. Trial has been retrospectively registered at ClinicalTrials.gov (NCT02792894). This study addresses implementation challenges in the real world by incorporating evidence-based intervention strategies with social, technological and business innovations. If proven effective, the study will contribute to scaled-up implementation of evidence-based packages for public mental health in low resource settings.

2013-01-01

Studies show that ADHD, conduct disorders, and anxiety disorders are clinical disorders mostly diagnosed in schoolstarters. The preschool medical examination in Bremen was therefore extended by behavioral screenings. Based on their screening results from the SEU (health examination for school entry) 2011 in Bremen, 67 preschoolers were tested for behavioral disorders. Subsequently, children with behavioral or emotional symptoms (N = 56) were compared to symptomfree controls (N = 52) for their cognitive, motoric, linguistic, and social-emotional development. Psychosocial health was obtained through external assessment by the parents and kindergarten teachers. Results of the WPPSI-III, M-ABC-2, and ET 6-6 were included in the analysis. 32 children met the criteria for behavioral disorders. Children with behavioral or emotional symptoms showed significant lower scores on tests measuring cognitive, motoric, linguistic and emotional development compared to controls. Results suggest that there is necessity to screen all preschoolers for behavioral disorders before entering school. Because children with clinical or subclinical behavioral disorders showed major developmental deficits compared to children without behavioral symptoms, it is essential to conduct a multiple assessment on children with suspected behavioral disorders to ensure early developmental support and adequate interventional programs.

Developmental origins of brain disorders: roles for dopamine

PubMed Central

Money, Kelli M.; Stanwood, Gregg D.

2013-01-01

Neurotransmitters and neuromodulators, such as dopamine, participate in a wide range of behavioral and cognitive functions in the adult brain, including movement, cognition, and reward. Dopamine-mediated signaling plays a fundamental neurodevelopmental role in forebrain differentiation and circuit formation. These developmental effects, such as modulation of neuronal migration and dendritic growth, occur before synaptogenesis and demonstrate novel roles for dopaminergic signaling beyond neuromodulation at the synapse. Pharmacologic and genetic disruptions demonstrate that these effects are brain region- and receptor subtype-specific. For example, the striatum and frontal cortex exhibit abnormal neuronal structure and function following prenatal disruption of dopamine receptor signaling. Alterations in these processes are implicated in the pathophysiology of neuropsychiatric disorders, and emerging studies of neurodevelopmental disruptions may shed light on the pathophysiology of abnormal neuronal circuitry in neuropsychiatric disorders.

2017-09-01

Children with developmental coordination disorder or sensory processing and integration difficulties face challenges to participation in daily living. To date there has been no exploration of the co-occurrence of developmental coordination disorders and sensory processing and integration difficulties. Records of children meeting Diagnostic and Statistical Manual - V criteria for developmental coordination disorder ( n  = 93) age 5 to 12 years were examined. Data on motor skills (Movement Assessment Battery for Children - 2) and sensory processing and integration (Sensory Processing Measure) were interrogated. Of the total sample, 88% exhibited some or definite differences in sensory processing and integration. No apparent relationship was observed between motor coordination and sensory processing and integration. The full sample showed high rates of some difficulties in social participation, hearing, body awareness, balance and motion, and planning and ideation. Further, children with co-morbid autistic spectrum disorder showed high rates of difficulties with touch and vision. Most, but not all, children with developmental coordination disorder presented with some difficulties in sensory processing and integration that impacted on their participation in everyday activities. Sensory processing and integration difficulties differed significantly between those with and without co-morbid autistic spectrum disorder.

Developmental trauma disorder: pros and cons of including formal criteria in the psychiatric diagnostic systems

PubMed Central

2013-01-01

Background This article reviews the current debate on developmental trauma disorder (DTD) with respect to formalizing its diagnostic criteria. Victims of abuse, neglect, and maltreatment in childhood often develop a wide range of age-dependent psychopathologies with various mental comorbidities. The supporters of a formal DTD diagnosis argue that post-traumatic stress disorder (PTSD) does not cover all consequences of severe and complex traumatization in childhood. Discussion Traumatized individuals are difficult to treat, but clinical experience has shown that they tend to benefit from specific trauma therapy. A main argument against inclusion of formal DTD criteria into existing diagnostic systems is that emphasis on the etiology of the disorder might force current diagnostic systems to deviate from their purely descriptive nature. Furthermore, comorbidities and biological aspects of the disorder may be underdiagnosed using the DTD criteria. Summary Here, we discuss arguments for and against the proposal of DTD criteria and address implications and consequences for the clinical practice. PMID:23286319

Laterality and Lateralization in Autism Spectrum Disorder, Using a Standardized Neuro-Psychomotor Assessment.

PubMed

Paquet, A; Golse, B; Girard, M; Olliac, B; Vaivre-Douret, L

2017-01-01

A detailed assessment of laterality in children with Autism Spectrum Disorder (ASD) was realized, including handedness and other measures (muscle tone, manual performance, dominant eye), using a standardized battery for the developmental assessment of neuro-psychomotor functions. The results of the laterality tests relating to cerebral hemisphere organization (spontaneous gestural laterality and tonic laterality) were different in ASD children, and indicate that the cerebral organization could be disrupted. These assessments, added to the observations of usual laterality most often reported in the literature, provide better understanding of the developmental organization from the pathophysiological point of view in children with ASD.

2007-04-01

Prader-Willi syndrome (PWS) is a genetic disorder which has widespread developmental consequences including motor, cognitive and language delay. Previous research on PWS children has focused primarily on phonological development and dysfluency. In the present study, the lexical development of a boy with PWS was investigated in a series of 18 play sessions recorded over a 4 month period from the ages 3;7 to 3;11. In comparison to the language development of children with Down syndrome this child with PWS appears to display a distinct developmental pattern. The possibility of detailing a behavioural phenotype of genetic disorders affecting language development is discussed.

Barnett, Anna L; Wilmut, Kate; Plumb, Mandy S

2016-01-01

Introduction There is substantial evidence to support the relationship between transcription skills (handwriting and spelling) and compositional quality. For children with developmental coordination disorder, handwriting can be particularly challenging. While recent research has aimed to investigate their handwriting difficulties in more detail, the impact of transcription on their compositional quality has not previously been examined. The aim of this exploratory study was to examine compositional quality in children with developmental coordination disorder and to ascertain whether their transcription skills influence writing quality. Method Twenty-eight children with developmental coordination disorder participated in the study, with 28 typically developing age and gender matched controls. The children completed the ‘free-writing’ task from the detailed assessment of speed of handwriting tool, which was evaluated for compositional quality using the Wechsler objective language dimensions. Results The children with developmental coordination disorder performed significantly below their typically developing peers on five of the six Wechsler objective language dimensions items. They also had a higher percentage of misspelled words. Regression analyses indicated that the number of words produced per minute and the percentage of misspelled words explained 55% of the variance for compositional quality. Conclusion The handwriting difficulties so commonly reported in children with developmental coordination disorder have wider repercussions for the quality of written composition. PMID:27807392

Neurodevelopmental movement disorders - an update on childhood motor stereotypies.

PubMed

Barry, Sinéad; Baird, Gillian; Lascelles, Karine; Bunton, Penny; Hedderly, Tammy

2011-11-01

The term 'stereotypies' encompasses a diverse range of movements, behaviours, and/or vocalizations that are repetitive, lack clear function, and sometimes appear to have a negative impact upon an individual's life. This review aims to describe motor stereotypies. This study reviewed the current literature on the nature, aetiology, and treatment of motor stereotypies. Motor stereotypies occur commonly but not exclusively in autistic spectrum disorders. Similar movements are also found in otherwise healthy children and those suffering sensory impairment, social isolation, or severe intellectual disabilities; they may be persistent over time. Although often difficult, it is possible to define and differentiate stereotypies from other movement disorders such as tics through features of the history, such as earlier onset and examination, together with the presence or absence of associated neurological impairment or developmental difficulties. Co-occurrence with other disorders affecting frontostriatal brain systems, including attention-deficit-hyperactivity disorder, obsessive-compulsive disorder, and tic disorders, is common. The underlying function of motor stereotypies remains unclear but may include the maintenance of arousal levels. A neurogenetic aetiology is proposed but requires further study. When treatment is sought, there are both pharmacological and behavioural options. Behavioural treatments for motor stereotypies may in time be shown to be most effective; however, they are difficult to implement in children younger than 7 years old. © The Authors.

Diverse Developmental Disorders from The One Ring: Distinct Molecular Pathways Underlie the Cohesinopathies

PubMed Central

Horsfield, Julia A.; Print, Cristin G.; Mönnich, Maren

2012-01-01

The multi-subunit protein complex, cohesin, is responsible for sister chromatid cohesion during cell division. The interaction of cohesin with DNA is controlled by a number of additional regulatory proteins. Mutations in cohesin, or its regulators, cause a spectrum of human developmental syndromes known as the “cohesinopathies.” Cohesinopathy disorders include Cornelia de Lange Syndrome and Roberts Syndrome. The discovery of novel roles for chromatid cohesion proteins in regulating gene expression led to the idea that cohesinopathies are caused by dysregulation of multiple genes downstream of mutations in cohesion proteins. Consistent with this idea, Drosophila, mouse, and zebrafish cohesinopathy models all show altered expression of developmental genes. However, there appears to be incomplete overlap among dysregulated genes downstream of mutations in different components of the cohesion apparatus. This is surprising because mutations in all cohesion proteins would be predicted to affect cohesin’s roles in cell division and gene expression in similar ways. Here we review the differences and similarities between genetic pathways downstream of components of the cohesion apparatus, and discuss how such differences might arise, and contribute to the spectrum of cohesinopathy disorders. We propose that mutations in different elements of the cohesion apparatus have distinct developmental outcomes that can be explained by sometimes subtly different molecular effects. PMID:22988450

The occurrence of developmental regression in autism is one of the more puzzling features of this disorder. Although several studies have documented the validity of parental reports of regression using home videos, accumulating data suggest that most children who demonstrate regression also demonstrated previous, subtle, developmental differences.…

Epidemiological research suggests racial differences in the presentation of eating disorder symptoms. However, no studies have examined associations between race and eating disorder symptom trajectories across youth and adolescence, which is necessary to inform culturally sensitive prevention programs. The purpose of the current study was to examine the trajectories of eating disorder symptoms from childhood to young adulthood and to examine whether race was associated with trajectory group membership. Data were drawn from 2,305 Black and White girls who participated in a community-based longitudinal cohort study (Pittsburgh Girls Study) examining the development of psychopathology. The child and adult versions of the Eating Attitudes Test assessed self-reported eating disorder symptoms at six time points between ages 9 and 21 years. Growth mixture modeling was used to examine developmental trajectories of dieting, bulimia/food preoccupation, and total eating disorder symptom scores. Given potential confounds with race and disordered eating, financial strain (i.e., receiving public assistance) and weight were included as covariates. Four to six distinct developmental patterns were found across eating disorder symptoms, including none, increasing, decreasing, or increasing-decreasing trajectories. Black girls had a greater likelihood of being in the decreasing trajectories for dieting, bulimia/food preoccupation, and total eating disorder symptom scores. White girls were more likely to follow increasing trajectories of dieting and total eating disorder symptom scores compared to Black girls. These results highlight the importance of examining the influence of racial background on eating disorder symptoms and the potential need for differences in the timing and focus of prevention interventions in these groups.

Working memory arrest in children with high-functioning autism compared to children with attention-deficit/hyperactivity disorder: results from a 2-year longitudinal study.

The aim of this study was to analyse the development of verbal working memory in children with high-functioning autism compared to children with attention-deficit/hyperactivity disorder and typically developing children. A total of 34 children with high-functioning autism, 72 children with attention-deficit/hyperactivity disorder and 45 typically developing children (age 9-16 years) were included at baseline and followed up approximately 25 months later. The children were given a letter/number sequencing task to assess verbal working memory. The performance of children with high-functioning autism on verbal working memory did not improve after 2 years, while improvement was observed in children with attention-deficit/hyperactivity disorder and typically developing children. The results indicate a different developmental trajectory for verbal working memory in children with high-functioning autism compared to children with attention-deficit/hyperactivity disorder and typically developing children. More research is needed to construct a developmental framework more suitable for children with autism spectrum disorder. © The Author(s) 2014.

Reproduction Symposium: developmental programming of reproductive and metabolic health.

Padmanabhan, V; Veiga-Lopez, A

2014-08-01

Inappropriate programming of the reproductive system by developmental exposure to excess steroid hormones is of concern. Sheep are well suited for investigating developmental origin of reproductive and metabolic disorders. The developmental time line of female sheep (approximately 5 mo gestation and approximately 7 mo to puberty) is ideal for conducting sequential studies of the progression of metabolic and/or reproductive disruption from the developmental insult to manifestation of adult consequences. Major benefits of using sheep include knowledge of established critical periods to target adult defects, a rich understanding of reproductive neuroendocrine regulation, availability of noninvasive approaches to monitor follicular dynamics, established surgical approaches to obtain hypophyseal portal blood for measurement of hypothalamic hormones, and the ability to perform studies in natural setting thereby keeping behavioral interactions intact. Of importance is the ability to chronically instrument fetus and mother for determining early endocrine perturbations. Prenatal exposure of the female to excess testosterone (T) leads to an array of adult reproductive disorders that include LH excess, functional hyperandrogenism, neuroendocrine defects, multifollicular ovarian morphology, and corpus luteum dysfunction culminating in early reproductive failure. At the neuroendocrine level, all 3 feedback systems are compromised. At the pituitary level, gonadotrope (LH secretion) sensitivity to GnRH is increased. Multifollicular ovarian morphology stems from persistence of follicles as well as enhanced follicular recruitment. These defects culminate in progressive loss of cyclicity and reduced fecundity. Prenatal T excess also leads to fetal growth retardation, an early marker of adult reproductive and metabolic diseases, insulin resistance, hypertension, and behavioral deficits. Collectively, the reproductive and metabolic deficits of prenatal T-treated sheep provide proof of concept for the developmental origin of fertility and metabolic disorders. Studies with the environmental endocrine disruptor bisphenol A (BPA) show that reproductive disruptions found in prenatal BPA-treated sheep are similar to those seen in prenatal T-treated sheep. The ubiquitous exposure to endocrine disrupting compounds with steroidogenic potential via the environment and food sources calls for studies addressing the impact of developmental exposure to environmental steroid mimics on reproductive function.

2007-12-01

We studied whether children with severe developmental disabilities (SDDs) who have a comorbid behavioral disorder also have higher rates of special healthcare needs (SHCNs). We used a matched-comparison control group design to establish whether SHCNs were higher in children with SDDs with behavioral disorders versus children with SDDs without behavioral disorders. Thirty-six children were matched for age (mean 12 y 6 mo; range 5 y 2 mo-18 y 8 mo), sex (24 males, 12 females), ethnicity (22 non-white), mental retardation level (22 moderate, eight severe, six profound), and Diagnostic and Statistical Manual of Mental Disorders, 4th edition axis I diagnosis (18 autism spectrum disorder, 10 specified syndrome, eight mental retardation not otherwise specified). Measures included the Achenbach Child Behavior Checklist, behavioral observation, health status examination, and Childhood Health Questionnaire (CHQ). Children with SDDs with behavioral disorders had significantly higher levels of SHCN, as measured by the CHQ and health status examination. Children with SDDs with behavioral disorders had a twofold higher incidence of SHCNs than children with SDDs without behavioral disorders. No difference was observed in the number or types of prescription medication that children received. The findings suggest that SHCNs contribute to the occurrence and/or intensity of behavioral disorders in children with SDD and may require interdisciplinary care coordination.

Catatonic features in adolescents with schizophrenia with and without a comorbid pervasive developmental disorder

PubMed Central

2014-01-01

Background Catatonia has been associated with both schizophrenia and pervasive developmental disorders. The aim of this study was to evaluate catatonic features among adolescents suffering from schizophrenia. Further, we compared these features between adolescents with a comorbid pervasive developmental disorder and those without one. Finally, we wanted to compare the profile of catatonia-like features of our schizophrenia patients to that described earlier among persons with autism spectrum disorders. Methods The study comprised a consecutive sample of 18 adolescents with schizophrenia (mean age 15.6 years, SD 1.4) and their families. Diagnosis of schizophrenia was assessed with the Schedule for Affective Disorders and Schizophrenia for School-Aged Children – Present and Life-Time (K-SADS-PL) for the DSM-IV. The Diagnostic Interview for Social and Communication Disorders version 11 was used to assess catatonic features. Results All adolescents with schizophrenia had showed some lifetime catatonic features. Approximately 78% of them had already expressed these features before the age of 10. The number of catatonic features before the age of 10 was significantly higher among the adolescents with a comorbid pervasive developmental disorder compared to those without one. The numbers of catatonic features after the age of 10 did not significantly differ between the two groups. Over three-quarters of schizophrenia patients shared four lifetime catatonic features: “lacks facial expression”, “odd intonation”, “poor eye contact” and “lack of cooperation”. Conclusions Adolescent schizophrenia patients with a comorbid pervasive developmental disorder show many catatonic features in childhood whereas those without one seem to develop these features first in adolescence. Catatonic features exhibited by adolescents with schizophrenia resemble those described among persons with pervasive developmental disorders without schizophrenia. PMID:24914405

The serial reaction time task (SRTT) has been used to study procedural learning in clinical populations. In this report, second-order meta-analysis was used to investigate whether disorder type moderates performance on the SRTT. Using this approach to quantitatively summarise past research, it was tested whether autism spectrum disorder, developmental coordination disorder, dyslexia, Parkinson's disease, schizophrenia, and specific language impairment differentially affect procedural learning on the SRTT. The main analysis revealed disorder type moderated SRTT performance (p=0.010). This report demonstrates comparable levels of procedural learning impairment in developmental coordination disorder, dyslexia, Parkinson's disease, schizophrenia, and specific language impairment. However, in autism, procedural learning is spared. Copyright © 2017 Elsevier Inc. All rights reserved.

Large-scale discovery of novel genetic causes of developmental disorders.

PubMed

2015-03-12

Despite three decades of successful, predominantly phenotype-driven discovery of the genetic causes of monogenic disorders, up to half of children with severe developmental disorders of probable genetic origin remain without a genetic diagnosis. Particularly challenging are those disorders rare enough to have eluded recognition as a discrete clinical entity, those with highly variable clinical manifestations, and those that are difficult to distinguish from other, very similar, disorders. Here we demonstrate the power of using an unbiased genotype-driven approach to identify subsets of patients with similar disorders. By studying 1,133 children with severe, undiagnosed developmental disorders, and their parents, using a combination of exome sequencing and array-based detection of chromosomal rearrangements, we discovered 12 novel genes associated with developmental disorders. These newly implicated genes increase by 10% (from 28% to 31%) the proportion of children that could be diagnosed. Clustering of missense mutations in six of these newly implicated genes suggests that normal development is being perturbed by an activating or dominant-negative mechanism. Our findings demonstrate the value of adopting a comprehensive strategy, both genome-wide and nationwide, to elucidate the underlying causes of rare genetic disorders.

Developmental stress has been hypothesised to interact with genetic predisposition to increase the risk of developing substance use disorders. Here we have investigated the effects of maternal separation-induced developmental stress using a behavioural proxy of methamphetamine preference in an animal model of attention-deficit/hyperactivity disorder, the spontaneously hypertensive rat, versus Wistar Kyoto and Sprague-Dawley comparator strains. Analysis of results obtained using a conditioned place preference paradigm revealed a significant strain × stress interaction with maternal separation inducing preference for the methamphetamine-associated compartment in spontaneously hypertensive rats. Maternal separation increased behavioural sensitization to the locomotor-stimulatory effects of methamphetamine in both spontaneously hypertensive and Sprague-Dawley strains but not in Wistar Kyoto rats. Our findings indicate that developmental stress in a genetic rat model of attention-deficit/hyperactivity disorder may foster a vulnerability to the development of substance use disorders.

2008-08-01

Current evaluations used by occupational therapists to assess and treat feeding problems derive mainly from the domain of dysphagia. The purpose of this article is to familiarize the reader with tools used, in research, for children with pervasive developmental disorders (PDD) and to determine if any of these meet the needs of occupational therapists. The following data bases were searched: Medline, CINAHL, HAPI and PsyINFO, using the terms pervasive developmental disorder, autism, Asperger syndrome, pervasive developmental disorder not otherwise specified, eating behavior, eating disorder, food preference, food selectivity, feeding disorders, picky eater and child. All articles published between 1980 and 2006 (n=27) were reviewed. A total of 20 studies met our selection criteria. Assessment methods are compared using the Disability Creation Model (DCP). The DCP is the Quebec alternative to the International Classification of Functioning, Disability and Health (ICF). None of the evaluation tools reviewed met all factors that may influence eating in children with PDD. Implications for research and practice in occupational therapy are discussed.

Total: 493 patientes (48.7% of the total of patients consulting); 32 healthy patients. odds ratio (95% confidence). The main risk factors for developing a developmental disorder (P<.005, 25% frequency in the consulting population) are: prematurity, male sex, mother with low education, early hospitalizations, and medical illnesses (all with a significant odds ratio). Also, having a mother with psychiatric illness doubles the risk of having a developmental disorder. It requires an interdisciplinary collaborative work between neonatologists, obstetricians, child psychiatrists and the primary care to detect early children at risk.

Acute dyskinetic reaction in a healthy toddler following methylphenidate ingestion.

PubMed

Waugh, Jeff L

2013-07-01

Acute dyskinetic or dystonic reactions are a long-recognized complication of medications that alter dopamine signaling. Most reactions occur following exposure to agents that block dopamine receptors (e.g., neuroleptics). However, agents that increase dopaminergic transmission (such as methylphenidate) can also trigger acute dyskinesias. This has been previously reported only in patients also taking dopamine antagonists or, less commonly, in children with developmental abnormalities. The present report describes a previously healthy toddler who developed transient torticollis and orolingual dyskinesias following accidental exposure to methylphenidate. He had no preexisting movement disorder, central nervous system injury, or developmental abnormalities--in short, none of the previously reported risk factors for this side effect. The unique features of this case led to the hypothesis that developmental shifts in dopamine signaling were the basis for his particular sensitivity to methylphenidate. If confirmed, this hypothesis has implications for the treatment of common childhood attentional and behavioral disorders. The article includes a literature review of dyskinetic/dystonic reactions in children and the developmental regulation of dopamine metabolism. Copyright © 2013 Elsevier Inc. All rights reserved.

[Specific developmental disorder of speech and language in adulthood].

PubMed

Vlassopoulos, M; Anagnostopoulos, D C

2012-06-01

Specific developmental disorder of speech and language is part of a more general category of neurodevelopmental disorders, which is encountered in 7-10% of the childhood population. These children exhibit a significant impairment in speech and language development, which cannot be justified by hearing impairment, cognitive impairment, neuromuscular or orofacial disorders, as well as by emotional or environmental factors. Specific developmental disorders of speech and language are often comorbid with other neurodevelopmental disorders, such as motor coordination disorder and ADHD. These disorders are usually detected in early childhood and commonly treated during the preschool and school years. Despite this fact clinical and empirical evidence suggest that often these disorders persist beyond the school years, even though the symptomatology may be differentiated. In this literature review, we address the question of whether specific developmental language disorders are encountered only during childhood, and, if they persist, how they are manifested in adulthood. Finally, possible factors which may lead to these manifestations are analyzed. A considerable body of research has shown that even though the symptoms of children with specific developmental language disorders are resolved before the end of childhood, a significant part of this population continues to have persisting difficulties through adolescence and into adulthood. The continuity of this disorder may sometimes be directly linked to language disorder, as in the case of learning impairments or, on the other hand, symptoms may be related with those of conduct disorders, social adjustment disorder, emotional and psychiatric disorders in adolescence and adulthood. It therefore appears that specific developmental language disorder is often an early symptom of other disorders in the future. Even though the precise mechanisms which are responsible for these disorders are not yet known, it is possible that a fragile neurobiological substratum in these disorders may explain why early symptoms are usually manifested as language disorders and later develop into other disorders over time. However, these symptom changes may be linked to other parameters, such as the increasing social and emotional demands made on these individuals with increasing age, which may be a contributing environmental parameter to an already vulnerable system. Despite all of the limitations in the longterm study of these children, it is suggested that in some way, and not in all cases, pathology may continue into adulthood, although with a different symptomatology, which is linked to behavioural and social adjustment, as well as with more pervasive psychiatric disorders. In conclusion, it is suggested that a continuum of services may be necessary for these cases into adulthood.

MVA can be used to address a wide variety of medical neuroimaging-related challenges including identifying variables associated with a measure of clinical importance (i.e. patient outcome), creating diagnostic tests, assisting in characterizing developmental disorders, understanding disease etiology, development and progression, assisting in treatment monitoring and much more. Compared to adults, imaging of developing immature brains has attracted less attention from MVA researchers. However, remarkable MVA research growth has occurred in recent years. This paper presents the results of a systematic review of the literature focusing on MVA technologies applied to neurodevelopmental disorders in fetal, neonatal and pediatric magnetic resonance imaging (MRI) of the brain. The goal of this manuscript is to provide a concise review of the state of the scientific literature on studies employing brain MRI and MVA in a pre-adult population. Neurological developmental disorders addressed in the MVA research contained in this review include autism spectrum disorder, attention deficit hyperactivity disorder, epilepsy, schizophrenia and more. While the results of this review demonstrate considerable interest from the scientific community in applications of MVA technologies in pediatric/neonatal/fetal brain MRI, the field is still young and considerable research growth remains ahead of us.

The aim is to assess repetition-based learning of procedures in children with developmental coordination disorder (DCD), reading disorder (RD) and attention-deficit hyperactivity disorder (ADHD). Participants included 187 children, studied in 4 groups: (a) DCD comorbid with RD and ADHD (DCD+RD+ADHD) (n = 30); (b) RD comorbid with ADHD (RD+ADHD) (n = 48); (c) ADHD (n = 19); and typically developing children (control group) (n = 90). Two procedural learning tasks were used: Assembly learning and Mirror drawing. Children were tested on 4 occasions for each task: 3 trials were consecutive and the fourth trial was performed after an interference task. Task performance by DCD+RD+ADHD children improved with training (P < .05); however, the improvement was significantly lower than that achieved by the other groups (RD+ADHD, ADHD and controls) (P < .05). In conclusion, children with DCD+RD+ADHD improve in their use of cognitive-motor procedures over a short training period. Aims of intervention in DCD+RD+ADHD should be based on individual learning abilities. © The Author(s) 2015.

Experimental Models of Maternal Obesity and Neuroendocrine Programming of Metabolic Disorders in Offspring.

PubMed

Reynolds, Clare M; Segovia, Stephanie A; Vickers, Mark H

2017-01-01

Evidence from epidemiological, clinical, and experimental studies have clearly shown that disease risk in later life is increased following a poor early life environment, a process preferentially termed developmental programming. In particular, this work clearly highlights the importance of the nutritional environment during early development with alterations in maternal nutrition, including both under- and overnutrition, increasing the risk for a range of cardiometabolic and neurobehavioral disorders in adult offspring characterized by both adipokine resistance and obesity. Although the mechanistic basis for such developmental programming is not yet fully defined, a common feature derived from experimental animal models is that of alterations in the wiring of the neuroendocrine pathways that control energy balance and appetite regulation during early stages of developmental plasticity. The adipokine leptin has also received significant attention with clear experimental evidence that normal regulation of leptin levels during the early life period is critical for the normal development of tissues and related signaling pathways that are involved in metabolic and cardiovascular homeostasis. There is also increasing evidence that alterations in the epigenome and other underlying mechanisms including an altered gut-brain axis may contribute to lasting cardiometabolic dysfunction in offspring. Ongoing studies that further define the mechanisms between these associations will allow for identification of early risk markers and implementation of strategies around interventions that will have obvious beneficial implications in breaking a programmed transgenerational cycle of metabolic disorders.

Studies on long-term feeding and eating outcomes in children requiring gastrostomy tube feeding (GT) are scarce. The aim of this study was to describe children with developmental or acquired disorders receiving GT and to compare longitudinal eating and feeding outcomes. A secondary aim was to explore healthcare provision related to eating and feeding. This retrospective cohort study reviewed medical records of children in 1 administrative region of Sweden with GT placement between 2005 and 2012. Patient demographics, primary diagnoses, age at GT placement, and professional healthcare contacts prior to and after GT placement were recorded and compared. Feeding and eating outcomes were assessed 4 years after GT placement. The medical records of 51 children, 28 boys and 23 girls, were analyzed and grouped according to "acquired" (n = 13) or "developmental" (n = 38) primary diagnoses. At 4 years after GT placement, 67% were still using GT. Only 6 of 37 (16%) children with developmental disorders transferred to eating all orally, as opposed to 10 of 11 (91%) children with acquired disorders. Children with developmental disorders were younger at the time of GT placement and displayed a longer duration of GT activity when compared with children with acquired disorders. This study demonstrates a clear difference between children with developmental or acquired disorders in duration of GT activity and age at GT placement. The study further shows that healthcare provided to children with GT is in some cases multidisciplinary, but primarily focuses on feeding rather than eating. © 2018 American Society for Parenteral and Enteral Nutrition.

Developmentally sensitive cognitive behavioral therapy for adolescent school refusal: rationale and case illustration.

PubMed

2014-06-01

School refusal can be difficult to treat and the poorest treatment response is observed among older school refusers. This poor response may be explained, in part, by the impact of developmental transitions and tasks upon the young person, their family, and the treatment process. This paper describes and illustrates the @school program, a cognitive behavioral therapy (CBT) designed to promote developmental sensitivity when planning and delivering treatment for adolescent school refusal. Treatment is modularized and it incorporates progress reviews, fostering a planned yet flexible approach to CBT. The treatment is illustrated in the case of Allison, a 16-year-old female presenting with major depressive disorder and generalized anxiety disorder. A case formulation guided the selection, sequencing, and pacing of modules targeting predisposing, precipitating, perpetuating, and protective factors. Treatment comprised 16 sessions with Allison (interventions addressing depression, anxiety, and school attendance) and 15 concurrent sessions with her mother (strategies to facilitate an adolescent's school attendance), including two sessions with Allison and mother together (family communication and problem solving to reduce parent-adolescent conflict). Two treatment-related consultations were also conducted with Allison's homeroom teacher. Allison's school attendance improved during the course of treatment. By post-treatment, there was a decrease in internalizing behavior, an increase in self-efficacy, and remission of depressive disorder and anxiety disorder. Clinically significant treatment gains were maintained at 2-month follow-up. Factors influencing outcome may include those inherent to the @school program together with less specific factors. Special consideration is given to parents' use of both authoritative and autonomy-granting approaches when helping an adolescent to attend school.

Children with a pervasive developmental disorder show in addition to core symptoms a variety of genetic syndromes as well as neurological problems, which are relevant for the treatment and the course of the disorder. The objective of our study is to analyse the nature and the frequency of these co-morbid somatic disorders in relation to the level of intellectual functioning of the patients. The sample consists of 601 patients with a pervasive developmental disorder diagnosed at the Department of Developmental Disorders at the Heckscher-Klinikum between 1997 and 2007. In addition to genetic syndromes, we also recorded a variety of neurological disorders. 373 of the patients (62%) had at least one additional diagnosis and 121 (20%) had at least two additional diagnoses on Axis IV of the multi-axial classification scheme. Genetic syndromes were found in 6% of the patients (N = 37). Movement disorders (N = 214; 35.6%) and epilepsy (N = 98; 16.3%) were the most frequent neurological disorders. Children with mental retardation showed significantly more somatic diagnoses than children without mental retardation. Children with pervasive developmental disorders show a wide variety of co-morbid somatic problems, which are relevant for the treatment and the course of the disorder. Children with autism and mental retardation show more co-morbid conditions and are more impaired in their psychosocial adaptation than children with autism without mental retardation.

[Simple and useful evaluation of motor difficulty in childhood (9-12 years old children ) by interview score on motor skills and soft neurological signs--aim for the diagnosis of developmental coordination disorder].

Many children with developmental disorders are known to have motor impairment such as clumsiness and poor physical ability;however, the objective evaluation of such difficulties is not easy in routine clinical practice. In this study, we aimed to establish a simple method for evaluating motor difficulty of childhood. This method employs a scored interview and examination for detecting soft neurological signs (SNSs). After a preliminary survey with 22 normal children, we set the items and the cutoffs for the interview and SNSs. The interview consisted of questions pertaining to 12 items related to a child's motor skills in his/her past and current life, such as skipping, jumping a rope, ball sports, origami, and using chopsticks. The SNS evaluation included 5 tests, namely, standing on one leg with eyes closed, diadochokinesia, associated movements during diadochokinesia, finger opposition test, and laterally fixed gaze. We applied this method to 43 children, including 25 cases of developmental disorders. Children showing significantly high scores in both the interview and SNS were assigned to the "with motor difficulty" group, while those with low scores in both the tests were assigned to the "without motor difficulty" group. The remaining children were assigned to the "with suspicious motor difficulty" group. More than 90% of the children in the "with motor difficulty" group had high impairment scores in Movement Assessment Battery for Children (M-ABC), a standardized motor test, whereas 82% of the children in the "without motor difficulty" group revealed no motor impairment. Thus, we conclude that our simple method and criteria would be useful for the evaluation of motor difficulty of childhood. Further, we have discussed the diagnostic process for developmental coordination disorder using our evaluation method.

This study examined social behaviors related to attachment in children with autistic disorder and the differences in these behaviors from those observed in developmentally disabled children. Additionally, we aimed to investigate the relationship between attachment behaviors and clinical variables, such as age, cognitive development, severity of autism, language development, and mothers' attachment styles. The study group consisted of 19 children with autistic disorder (mean age: 37.9 +/- 6.8 months) and the control group consisted of 18 developmentally disabled children without autistic disorder that were matched with respect to age, gender, and cognitive development. The Childhood Autism Rating Scale (CARS) was administered to all the children by two child psychiatrists. Mothers completed the Relationships Scale Questionnaire (RSQ). Cognitive development of the children was assessed with the Stanford-Binet intelligence scale. Attachment behaviors of the children were evaluated with a modified Strange Situation Procedure (SSP). Attachment behaviors in the children with autistic disorder and in the children with developmental disabilities were similar. In contrast to the developmentally disabled group, the children with autistic disorder stayed closer toward their mothers compared with their responses to strangers. In the autistic disorder group, attachment behaviors were not associated with age, intelligence quotient, or mothers' attachment styles; however, a significant relationship between the severity of autism and the presence of speech was observed. Parents' understanding of the attachment needs and the attachment behaviors of their autistic children in the early stages of the disorder may lead to more secure attachment relationships and improved social development.

Maternal impulse control disability and developmental disorder traits are risk factors for child maltreatment.

Previous work has suggested that maternal developmental disorder traits related to autism spectrum disorder (ASD) and attention-deficit hyperactivity disorder (ADHD) are significantly associated with child maltreatment. However, there may be other important maternal characteristics that contribute to child maltreatment. We hypothesized that maternal impulse control disability may also affect child maltreatment in addition to maternal developmental disorder traits. We aimed to test this hypothesis via a cohort study performed in Tokyo (n = 1,260). Linear regression analyses using the Behavioural Inhibition/Behavioural Activation Scales, the self-administered short version of the Pervasive Developmental Disorders Autism Society Japan Rating Scale, the short form of the Adult Attention-Deficit Hyperactivity Disorder Self-Report Scale, and the Child Maltreatment Scale, revealed that excessive inhibition of behaviour and affect, which is impulse control disability, is significantly associated with child maltreatment (b = 0.031, p = 0.018) in addition to maternal developmental disorder traits (ASD: b = 0.052, p = 0.004; ADHD: b = 0.178, p < 0.001). Logistic regression analyses revealed that ASD (adjusted odds ratio [AOR] = 1.083, p = 0.014) and high behavioural inhibition (AOR = 1.068, p = 0.016) were significantly associated with moderate child maltreatment, while ADHD was associated (AOR = 1.034, p = 0.022) with severe child maltreatment. These maternal characteristics may inform the best means for prevention and management of child maltreatment cases.

The co-occurrence of mental disorders in children and adolescents with intellectual disability/intellectual developmental disorder

2016-01-01

Purpose of review The study summarizes supportive epidemiological data regarding the true co-occurrence (comorbidity) and course of mental disorders in children with intellectual disability/intellectual developmental disorders (ID/IDD) across the lifespan. Recent findings Published studies involving representative populations of children and adolescents with ID/IDD have demonstrated a three to four-fold increase in prevalence of co-occurring mental disorders. The effect of age, sex, and severity (mild, moderate, severe, and profound) and socioeconomic status on prevalence is currently not clearly understood. To date there are no prevalence estimates of co-occurring mental disorders in youth identified using the new DSM-5 (and proposed ICD-11) definition of ID/IDD using measures of intellectual functions and deficits in adaptive functioning with various severity levels defined on the basis of adaptive functioning, and not intellectual quotient scores. Summary The true relationship between two forms of morbidity remains complex and causal relationships that may be true for one disorder may not apply to another. The new conceptualization of ID/IDD offers a developmentally better informed psychobiological approach that can help distinguish co-occurrence of mental disorders within the neurodevelopmental section with onset during the developmental period as well as the later onset of other mental disorders.

Developmental approaches to autism treatment aim to establish strong interpersonal relationships through joint play. These approaches have emerging empirical support; however, there is a need for further research documenting the procedures and demonstrating their effectiveness. This pilot study evaluated changes in parent behavior and child autism symptoms following a 12-week Developmental Reciprocity Treatment parent-training program. A total of 22 children with autism spectrum disorder between 2 and 6 years (mean age = 44.6 months, standard deviation = 12.7) and a primary caregiver participated in 12 weekly sessions of Developmental Reciprocity Treatment parent training, covering topics including introduction to developmental approaches, supporting attention and motivation, sensory regulation and sensory-social routines, imitation/building nonverbal communication, functional language development, and turn taking. Results indicated improvement in aspects of parent empowerment and social quality of life. Improvement in core autism symptoms was observed on the Social Responsiveness Scale total score (F(1,19): 5.550, p = 0.029), MacArthur-Bates Communicative Development Inventories number of words produced out of 680 (F(1,18): 18.104, p = 0.000), and two subscales of the Repetitive Behavior Scale, Revised (compulsive, p = 0.046 and restricted, p = 0.025). No differences in sensory sensitivity were observed on the Short Sensory Profile. Findings from this pilot study indicate that Developmental Reciprocity Treatment shows promise and suggest the need for future controlled trials of this developmentally based intervention.

This study investigated the psychometric properties of the Child and Family Quality of Life scale, a measure of psychosocial quality of life in those with autism and related developmental disorders. Parents of 212 children suspected of autism spectrum disorder completed the Child and Family Quality of Life prior to a diagnostic evaluation. Results indicated that the Child and Family Quality of Life measured six unique quality-of-life constructs (child, family/caregiver, financial, external support, partner relationship, and coping), had good reliability across score ranges and exhibited expected patterns of convergent validity. Caregivers of autism spectrum disorder-affected children reported reduced family quality of life prior to the time of diagnosis relative to caregivers of children with other developmental disabilities. The Child and Family Quality of Life is a brief, reliable measure for assessing psychosocial quality of life in families affected by developmental disability. This study is the first to demonstrate impairments in family quality of life early in the developmental course of autism spectrum disorder, prior to formal diagnosis. In addition to traditional child-focused intervention strategies, families with autism spectrum disorder-affected children require early, broad intervention strategies that positively impact the whole family. © The Author(s) 2015.

Local data on the occurrence of motor problems in children with attention deficit hyperactivity disorder are not available but an understanding of this important issue may enable better planning of medical services. We aimed to determine the prevalence of motor problems in children with attention deficit hyperactivity disorder in a local population. In this descriptive cross-sectional study, children aged 6 to 9 years diagnosed with attention deficit hyperactivity disorder over a period of 6 months from 1 July to 31 December 2011 were recruited from the Joint Paediatric and Child Psychiatric ADHD Program in New Territories East Cluster in Hong Kong. Movement Assessment Battery for Children and Developmental Coordination Disorder Questionnaire-Chinese version were used to determine the presence of motor problems. Data from 95 participants were included in the final analysis. The number of children who had no, borderline, or definite motor problems was 63, 15, and 17, respectively. It is estimated that up to one third of local children with attention deficit hyperactivity disorder might have developmental coordination disorder. Motor problems are common in local children with attention deficit hyperactivity disorder and figures are comparable with those from other parts of the world. Despite the various limitations of this study, the magnitude of the problem should not be overlooked.

Annual Research Review: Attachment disorders in early childhood – clinical presentation, causes, correlates and treatment

Zeanah, Charles H.; Gleason, Mary Margaret

2015-01-01

Background Though noted in the clinical literature for more than 50 years, attachment disorders have been studied systematically only recently. In part because of the ubiquity of attachments in humans, determining when aberrant behavior is best explained as an attachment disorder as opposed to insecure attachment has led to some confusion. In this selective review, we consider the literature on reactive attachment disorder and disinhibited social engagement disorder and describe an emerging consensus about a number of issues, while also noting some areas of controversy and others where we lack clear answers. We include a brief history of the classification of the disorders, as well as measurement issues. We describe their clinical presentation, causes and vulnerability factors, and clinical correlates, including the relation of disorders to secure and insecure attachment classifications. We also review what little is known and what more we need to learn about interventions. Methods We conducted a literature search using PubMed, PsycINFO, and Cochrane Library databases, using search terms “reactive attachment disorder,” “attachment disorder,” “indiscriminate behavior,” “indiscriminate friendliness,” “indiscriminate socially disinhibited reactive attachment disorder,” “disinhibited social engagement disorder,” and “disinhibited social behavior.” We also contacted investigators who have published on these topics. Findings A growing literature has assessed behaviors in children who have experienced various types of adverse caregiving environments reflecting signs of putative attachment disorders, though fewer studies have investigated categorically defined attachment disorders. The evidence for two separate disorders is considerable, with reactive attachment disorder indicating children who lack attachments despite the developmental capacity to form them, and disinhibited social engagement disorder indicating children who lack developmentally appropriate reticence with unfamiliar adults and who violate socially sanctioned boundaries. Conclusions Though many questions remain to be answered, especially regarding appropriate interventions, we know considerably more about attachment disorders than we did only a decade ago.

Cognitive Profiles of Preschool Children with Developmental Coordination Disorders and ADHD Studies confirm that developmental coordination disorders (DCD) are often accompanied by ADHD. It is important to know why children with combined disorders show a special profile in a common intelligence test (WPPSI-III). For this purpose, the WPPSI-III results of a total of 125 children aged five to six years with diagnosed isolated DCD, isolated ADHD, combined disorders and a normative sample were compared. Children with isolated ADHD showed the best cognitive profile. Children of all three diagnosis subgroups presented significantly poorer abilities in all WPPSI-III scales than the normative sample. In comparison with preschoolers showing isolated ADHD, children with DCD and ADHD have a significant lower Processing Speed Quotient.

The transcriptional underpinnings of brain development remain poorly understood, particularly in humans and closely related non-human primates. We describe a high resolution transcriptional atlas of rhesus monkey brain development that combines dense temporal sampling of prenatal and postnatal periods with fine anatomical parcellation of cortical and subcortical regions associated with human neuropsychiatric disease. Gene expression changes more rapidly before birth, both in progenitor cells and maturing neurons, and cortical layers and areas acquire adult-like molecular profiles surprisingly late postnatally. Disparate cell populations exhibit distinct developmental timing but also unexpected synchrony of processes underlying neural circuit construction including cell projection and adhesion. Candidate risk genes for neurodevelopmental disorders including primary microcephaly, autism spectrum disorder, intellectual disability, and schizophrenia show disease-specific spatiotemporal enrichment within developing neocortex. Human developmental expression trajectories are more similar to monkey than rodent, and approximately 9% of genes show human-specific regulation with evidence for prolonged maturation or neoteny.

Maternal Obesity, Inflammation, and Developmental Programming

PubMed Central

Segovia, Stephanie A.; Vickers, Mark H.; Reynolds, Clare M.

2014-01-01

The prevalence of obesity, especially in women of child-bearing age, is a global health concern. In addition to increasing the immediate risk of gestational complications, there is accumulating evidence that maternal obesity also has long-term consequences for the offspring. The concept of developmental programming describes the process in which an environmental stimulus, including altered nutrition, during critical periods of development can program alterations in organogenesis, tissue development, and metabolism, predisposing offspring to obesity and metabolic and cardiovascular disorders in later life. Although the mechanisms underpinning programming of metabolic disorders remain poorly defined, it has become increasingly clear that low-grade inflammation is associated with obesity and its comorbidities. This review will discuss maternal metainflammation as a mediator of programming in insulin sensitive tissues in offspring. Use of nutritional anti-inflammatories in pregnancy including omega 3 fatty acids, resveratrol, curcumin, and taurine may provide beneficial intervention strategies to ameliorate maternal obesity-induced programming.

Gender Differences in Anxiety Trajectories from Middle to Late Adolescence

Ohannessian, Christine McCauley; Milan, Stephanie; Vannucci, Anna

2016-01-01

Although developmental trajectories of anxiety symptomatology have begun to be explored, most research has focused on total anxiety symptom scores during childhood and early adolescence, using racially/ethnically homogenous samples. Understanding the heterogeneous courses of anxiety disorder symptoms during middle to late adolescence has the potential to clarify developmental risk models of anxiety and to inform prevention programs. Therefore, this study specifically examined gender differences in developmental trajectories of anxiety disorder symptoms (generalized anxiety disorder, panic disorder, and social anxiety disorder) from middle to late adolescence in a diverse community sample (N=1,000; 57% female; 65% White), assessed annually over two years. Latent growth curve modeling revealed that girls exhibited a slight linear decrease in generalized anxiety disorder, panic disorder, and social anxiety disorder symptoms, whereas boys exhibited a stable course. These models suggested that one trajectory was appropriate for panic disorder symptoms in both girls and boys. Growth mixture models indicated the presence of four latent generalized anxiety disorder symptom trajectory classes: low increasing, moderate decreasing slightly, high decreasing, and very high decreasing rapidly. Growth mixture models also suggested the presence of five latent social anxiety disorder symptom trajectory classes: a low stable trajectory class and four classes that were qualitatively similar to the latent generalized anxiety disorder trajectories. For both generalized anxiety disorder and social anxiety disorder symptoms, girls were significantly more likely than boys to be in trajectory classes characterized by moderate or high initial symptoms that subsequently decreased over time. These findings provide novel information regarding the developmental course of anxiety disorder symptoms in adolescents. PMID:27889856

Nearly half of very preterm (VP) and extremely preterm (EP) infants suffers from minor disabilities. The paper overviews the literature dealing with motor problems other than cerebral palsy (CP) during infancy and preschool age. The term "minor motor problems" indicates a wide spectrum of motor disorders other than CP; "minor" does not mean "minimal", as a relevant proportion of the preterm infants will develop academic and behavioural problems at school age. Early onset disorders consist of abnormal general movements (GMs), transient dystonia and postural instability; these conditions usually fade during the first months. They were underestimated in the past; recently, qualitative assessment of GMs using Prechtl's method has become a major item of the neurological examination. Late onset disorders include developmental coordination disorder (DCD) and/or minor neurological dysfunction (MND): both terms cover partly overlapping problems. Simple MND (MND-1) and complex MND (MND-2) can be identified and MND-2 gives a higher risk for learning and behavioural disorders. A relationship between the quality of GMs and MND in childhood has been recently described. The Touwen infant neurological examination (TINE) can reliably detect neurological signs of MND even in infancy. However, the prognostic value of these disorders requires further investigations.

2011-01-01

Repetitive and stereotyped behaviours in the form of stereotyped interests or specific routine activities are one ofthe diagnostic criteria in pervasive developmental disorders. The occurrence of repetitive behaviours in patients with pervasive developmental disorders is a starting point for questions about the type and classification criteria of such behaviours. The aim of the article is to present case studies of patients with pervasive developmental disorders and co-morbid symptoms in the form of routine activities, tics, obsessive-compulsive symptoms or stereotyped behaviours. The first case study describes a patient with Asperger's syndrome and obsessive compulsive symptoms. The diagnostic problems regarding complex motor tics are discussed in the second case study which describes a patient with Asperger's syndrome and Gilles de la Tourette syndrome. The third and fourth case study describes mono-zygotic twins with so called High Functioning Autism whose repetitive activities point to either obsessive compulsive symptoms, stereotypic movements, need for absolute consistency or echopraxia. The possible comorbidity of pervasive developmental disorders and symptoms in the form of repetitive behaviours, possible interactions as well as diagnostic challenges is discussed in the article.

Developmental psychopathology: Attention Deficit Hyperactivity Disorder (ADHD).

PubMed

Schmidt, Sören; Petermann, Franz

2009-09-17

Attention Deficit/Hyperactivity Disorder (ADHD), formerly regarded as a typical childhood disorder, is now known as a developmental disorder persisting over the lifespan. Starting in preschool-age, symptoms vary depending on the age group affected. According to the variability of ADHD-symptoms and the heterogeneity of comorbid psychiatric disorders, a broad review of recent studies was performed. These findings were summarized in a developmental psychopathological model, documenting relevant facts on a timeline. Based on a genetic disposition and a neuropsychological deregulation, there is evidence for factors which persist across the lifespan, change age-dependently, or show validity in a specific developmental phase. Qualitative changes can be found for children in preschool-age and adults. These differences have implications for clinical practice as they can be used for prevention, diagnostic proceedings, and therapeutic intervention as well as for planning future studies. The present article is a translated and modified version of the German article "Entwicklungspsychopathologie der ADHS", published in Zeitschrift für Psychiatrie, Psychologie und Psychotherapie, 56, 2008, S. 265-274.

This case study explains how a psychotherapy previously used with adults can be used with adolescents by focusing on the specific developmental issues associated with adolescence. Bipolar disorder is a damaging disorder to experience during the developmental phase of adolescence. Interpersonal social rhythm psychotherapy has been developed as an adjunct to medication for managing bipolar disorder and shows some promising outcomes in adults. This is a single case study design drawn from a larger randomised control trial of two psychotherapies for bipolar disorder. The case study addressed the question: How can Interpersonal social rhythm therapy be applied with adolescents who have bipolar disorder? This study used a purposeful sampling process by selecting the youngest adolescent participating in the randomised control trial. All the subject's sessions of Interpersonal social rhythm therapy were taped, transcribed and analysed. The analysis involved describing the process of psychotherapy as it occurred over time, mapping the process as a trajectory across the three phases of psychotherapy experience and focusing the analysis around the impact of bipolar disorder and IPSRT on adolescent developmental issues, specifically the issue of identity development. Interpersonal social rhythm therapy allowed the therapist to address developmental issues within its framework. As a result of participation in the psychotherapy the adolescent was able to manage her mood symptoms and develop a sense of identity that was age-appropriate. Interpersonal social rhythm therapy provided the adolescent in the case study the opportunity to consider what it meant to have bipolar disorder and to integrate this meaning into her sense of self. Bipolar disorder is a chronic and recurring disorder that can have a serious impact on development and functioning. Interpersonal social rhythm therapy provides an approach to nursing care that enables adolescents to improve social functioning.

Diagnostic stability of autism spectrum disorder in toddlers prospectively identified in a community-based setting: Behavioural characteristics and predictors of change over time.

PubMed

Barbaro, Josephine; Dissanayake, Cheryl

2017-10-01

Autism spectrum disorder diagnoses in toddlers have been established as accurate and stable across time in high-risk siblings and clinic-referred samples. Few studies have investigated diagnostic stability in children prospective identified in community-based settings. Furthermore, there is a dearth of evidence on the individual behaviours that predict diagnostic change over time. The stability and change of autism spectrum disorder diagnoses were investigated from 24 to 48 months in 77 children drawn from the Social Attention and Communication Study. Diagnostic stability was high, with 88.3% overall stability and 85.5% autism spectrum disorder stability. The behavioural markers at 24 months that contributed to diagnostic shift off the autism spectrum by 48 months included better eye contact, more directed vocalisations, the integration of gaze and directed vocalisations/gestures and higher non-verbal developmental quotient. These four variables correctly predicted 88.7% of children into the autism spectrum disorder-stable and autism spectrum disorder-crossover groups overall, with excellent prediction for the stable group (96.2%) and modest prediction for the crossover group (44.4%). Furthermore, non-verbal developmental quotient at 24 months accounted for the significant improvement across time in 'Social Affect' scores on the Autism Diagnostic Observation Schedule for both groups and was the only unique predictor of diagnostic crossover. These findings contribute to the body of evidence on the feasibility of diagnoses at earlier ages to facilitate children's access to interventions to promote positive developmental outcomes.

Tic disorders are moderately heritable common psychiatric disorders that can be highly troubling, both in childhood and in adulthood. In this study, we report results obtained in the first epigenome-wide association study (EWAS) of tic disorders. The subjects are participants in surveys at the Netherlands Twin Register (NTR) and the NTR biobank project. Tic disorders were measured with a self-report version of the Yale Global Tic Severity Scale Abbreviated version (YGTSS-ABBR), included in the 8th wave NTR data collection (2008). DNA methylation data consisted of 411,169 autosomal methylation sites assessed by the Illumina Infinium HumanMethylation450 BeadChip Kit (HM450k array). Phenotype and DNA methylation data were available in 1,678 subjects (mean age = 41.5). No probes reached genome-wide significance (p < 1.2 × 10(-7)). The strongest associated probe was cg15583738, located in an intergenic region on chromosome 8 (p = 1.98 × 10(-6)). Several of the top ranking probes (p < 1 × 10(-4)) were in or nearby genes previously associated with neurological disorders (e.g., GABBRI, BLM, and ADAM10), warranting their further investigation in relation to tic disorders. The top significantly enriched gene ontology (GO) terms among higher ranking methylation sites included anatomical structure morphogenesis (GO:0009653, p = 4.6 × 10-(15)) developmental process (GO:0032502, p = 2.96 × 10(-12)), and cellular developmental process (GO:0048869, p = 1.96 × 10(-12)). Overall, these results provide a first insight into the epigenetic mechanisms of tic disorders. This first study assesses the role of DNA methylation in tic disorders, and it lays the foundations for future work aiming to unravel the biological mechanisms underlying the architecture of this disorder.

Feasibility of the music therapy assessment tool for awareness in disorders of consciousness (MATADOC) for use with pediatric populations.

Magee, Wendy L; Ghetti, Claire M; Moyer, Alvin

2015-01-01

Measuring responsiveness to gain accurate diagnosis in populations with disorders of consciousness (DOC) is of central concern because these patients have such complex clinical presentations. Due to the uncertainty of accuracy for both behavioral and neurophysiological measures in DOC, combined assessment approaches are recommended. A number of standardized behavioral measures can be used with adults with DOC with minor to moderate reservations relating to the measures' psychometric properties and clinical applicability. However, no measures have been standardized for use with pediatric DOC populations. When adapting adult measures for children, confounding factors include developmental considerations for language-based items included in all DOC measures. Given the lack of pediatric DOC measures, there is a pressing need for measures that are sensitive to the complex clinical presentations typical of DOC and that can accommodate the developmental levels of pediatric populations. The music therapy assessment tool for awareness in disorders of consciousness (MATADOC) is a music-based measure that has been standardized for adults with DOC. Given its emphasis on non-language based sensory stimuli, it is well-suited to pediatric populations spanning developmental stages. In a pre-pilot exploratory study, we examined the clinical utility of this measure and explored trends for test-retest and inter-rater agreement as well as its performance against external reference standards. In several cases, MATADOC items in the visual and auditory domains produced outcomes suggestive of higher level functioning when compared to outcomes provided by other DOC measures. Preliminary findings suggest that the MATADOC provides a useful protocol and measure for behavioral assessment and clinical treatment planning with pediatric DOC. Further research with a larger sample is warranted to test a version of the MATADOC that is refined to meet developmental needs of pediatric DOC populations.

Focus On: Neurotransmitter Systems

PubMed Central

Valenzuela, C. Fernando; Puglia, Michael P.; Zucca, Stefano

2011-01-01

Neurotransmitter systems have been long recognized as important targets of the developmental actions of alcohol (i.e., ethanol). Short- and long-term effects of ethanol on amino acid (e.g., γ-aminobutyric acid and glutamate) and biogenic amine (e.g., serotonin and dopamine) neurotransmitters have been demonstrated in animal models of fetal alcohol spectrum disorders (FASD). Researchers have detected ethanol effects after exposure during developmental periods equivalent to the first, second, and third trimesters of human pregnancy. Results support the recommendation that pregnant women should abstain from drinking—even small quantities—as effects of ethanol on neurotransmitter systems have been detected at low levels of exposure. Recent studies have elucidated new mechanisms and/or consequences of the actions of ethanol on amino acid and biogenic amine neurotransmitter systems. Alterations in these neurotransmitter systems could, in part, be responsible for many of the conditions associated with FASD, including (1) learning, memory, and attention deficits; (2) motor coordination impairments; (3) abnormal responsiveness to stress; and (4) increased susceptibility to neuropsychiatric disorders, such as substance abuse and depression, and also neurological disorders, such as epilepsy and sudden infant death syndrome. However, future research is needed to conclusively establish a causal relationship between these conditions and developmental dysfunctions in neurotransmitter systems. PMID:23580048

Autism Spectrum Disorder: Classification, diagnosis and therapy.

Sharma, Samata R; Gonda, Xenia; Tarazi, Frank I

2018-05-12

Autism Spectrum Disorder (ASD) refers to a group of neurodevelopmental disorders including autism, Asperger's syndrome (AS) and pervasive developmental disorder-not otherwise specified (PDD-NOS). The new diagnostic criteria of ASD focuses on two core domains: social communication impairment and restricted interests/repetitive behaviors. The prevalence of ASD has been steadily increasing over the past two decades, with current estimates reaching up to 1 in 36 children. Hereditary factors, parental history of psychiatric disorders, pre-term births, and fetal exposure to psychotropic drugs or insecticides have all been linked to higher risk of ASD. Several scales such as the Childhood Autism Rating Scale (CARS), The Autism Spectrum Disorder-Observation for Children (ASD-OC), The Developmental, Dimensional, and Diagnostic Interview (3di), are available to aid in better assessing the behaviors and symptoms associated with ASD. Nearly 75% of ASD patients suffer from comorbid psychiatric illnesses or conditions, which may include attention-deficit hyperactivity disorder (ADHD), anxiety, bipolar disorder, depression, Tourette syndrome, and others. Both pharmacological and non-pharmacological interventions are available for ASD. Pharmacological treatments include psychostimulants, atypical antipsychotics, antidepressants, and alpha-2 adrenergic receptor agonists. These medications provide partial symptomatic relief of core symptoms of ASD or manage the symptoms of comorbid conditions. Non-pharmacological interventions, which show promising evidence in improving social interaction and verbal communication of ASD patients, include music therapy, cognitive behavioral therapy and social behavioral therapy. Hormonal therapies with oxytocyin or vasopressin receptor antagonists have also shown some promise in improving core ASD symptoms. The use of vitamins, herbal remedies and nutritional supplements in conjunction with pharmacological and behavioral treatment appear to have some effect in symptomatic improvement in ASD, though additional studies are needed to confirm these benefits. Developing novel disease-modifying therapies may prove to be the ultimate intervention for sustained improvement of symptoms in ASD. Copyright © 2018 Elsevier Inc. All rights reserved.

Peer problems mediate the relationship between developmental coordination disorder and behavioral problems in school-aged children.

2012-01-01

The aim of this study was to gain insights into the relationship between developmental coordination disorder, peer problems, and behavioral problems in school-aged children where both internalizing and externalizing behavioral problems were considered. We assumed that the relationship between developmental coordination disorder and internalizing/externalizing problems in school-aged children is mediated by peer problems and tested the hypothesis that a greater degree of motor impairment causes a greater degree of peer problems and thus a greater degree of internalizing or externalizing problems. Seventy boys and girls aged between 5 and 11 years were examined using the Movement Assessment Battery for Children 2 and the Intelligence and Developmental Scales. The results of path analysis showed that the relationship between developmental coordination disorder and internalizing/externalizing problems in school-aged children is mediated at least in part by peer problems. However, the cross-sectional design of the study does not provide conclusive evidence for a cause-effect relationship and only allows for the conservative prognosis that a greater degree of motor impairment may cause a greater degree of peer problems and thus a greater degree of internalizing/externalizing problems. Nevertheless, the results of this study emphasize the importance of being well-integrated in their peer group especially for children with developmental coordination disorder.

This methodological review draws attention to the challenges faced by intellectual and developmental disabilities researchers in the appropriate design and analysis of group comparison studies. We provide a brief overview of matching methodologies in the field, emphasizing group-matching designs used in behavioral research on cognition and language in neurodevelopmental disorders, including autism spectrum disorder, Fragile X syndrome, Down syndrome, and Williams syndrome. The limitations of relying on p values to establish group equivalence are discussed in the context of other existing methods: equivalence tests, propensity scores, and regression-based analyses. Our primary recommendation for advancing research on intellectual and developmental disabilities is the use of descriptive indices of adequate group matching: effect sizes (i.e., standardized mean differences) and variance ratios.

From emotion resonance to empathic understanding: a social developmental neuroscience account.

PubMed

Decety, Jean; Meyer, Meghan

2008-01-01

The psychological construct of empathy refers to an intersubjective induction process by which positive and negative emotions are shared, without losing sight of whose feelings belong to whom. Empathy can lead to personal distress or to empathic concern (sympathy). The goal of this paper is to address the underlying cognitive processes and their neural underpinnings that constitute empathy within a developmental neuroscience perspective. In addition, we focus on how these processes go awry in developmental disorders marked by impairments in social cognition, such as autism spectrum disorder, and conduct disorder. We argue that empathy involves both bottom-up and top-down information processing, underpinned by specific and interacting neural systems. We discuss data from developmental psychology as well as cognitive neuroscience in support of such a model, and highlight the impact of neural dysfunctions on social cognitive developmental behavior. Altogether, bridging developmental science and cognitive neuroscience helps approach a more complete understanding of social cognition. Synthesizing these two domains also contributes to a better characterization of developmental psychopathologies that impacts the development of effective treatment strategies.

Developmental Coordination Disorder, An Umbrella Term for Motor Impairments in Children: Nature and Co-Morbid Disorders

PubMed Central

Vaivre-Douret, Laurence; Lalanne, Christophe; Golse, Bernard

2016-01-01

Background: Developmental Coordination Disorder (DCD) defines a heterogeneous class of children exhibiting marked impairment in motor coordination as a general group of deficits in fine and gross motricity (subtype mixed group) common to all research studies, and with a variety of other motor disorders that have been little investigated. No consensus about symptoms and etiology has been established. Methods: Data from 58 children aged 6 to 13 years with DCD were collected on DSM-IV criteria, similar to DSM-5 criteria. They had no other medical condition and inclusion criteria were strict (born full-term, no medication, no occupational/physical therapy). Multivariate statistical methods were used to evidence relevant interactions between discriminant features in a general DCD subtype group and to highlight specific co-morbidities. The study examined age-calibrated standardized scores from completed assessments of psychological, neuropsychological, and neuropsychomotor functions, and more specifically the presence of minor neurological dysfunctions (MND) including neurological soft signs (NSS), without evidence of focal neurological brain involvement. These were not considered in most previous studies. Results: Findings show the salient DCD markers for the mixed subtype (imitation of gestures, digital perception, digital praxia, manual dexterity, upper, and lower limb coordination), vs. surprising co-morbidities, with 33% of MND with mild spasticity from phasic stretch reflex (PSR), not associated with the above impairments but rather with sitting tone (p = 0.004) and dysdiadochokinesia (p = 0.011). PSR was not specific to a DCD subtype but was related to increased impairment of coordination between upper and lower limbs and manual dexterity. Our results highlight the major contribution of an extensive neuro-developmental assessment (mental and physical). Discussion: The present study provides important new evidence in favor of a complete physical neuropsychomotor assessment, including neuromuscular tone examination, using appropriate standardized neurodevelopmental tools (common tasks across ages with age-related normative data) in order to distinguish motor impairments gathered under the umbrella term of developmental coordination disorders (subcortical vs. cortical). Mild spasticity in the gastrocnemius muscles, such as phasic stretch reflex (PSR), suggests disturbances of the motor pathway, increasing impairment of gross and fine motricity. These findings contribute to understanding the nature of motor disorders in DCD by taking account of possible co-morbidities (corticospinal tract disturbances) to improve diagnosis and adapt treatment programmes in clinical practice.

Early B cell factor 3 (EBF3) is a member of the highly evolutionarily conserved Collier/Olf/EBF (COE) family of transcription factors. Prior studies on invertebrate and vertebrate animals have shown that EBF3 homologs are essential for survival and that loss-of-function mutations are associated with a range of nervous system developmental defects, including perturbation of neuronal development and migration. Interestingly, aristaless-related homeobox (ARX), a homeobox-containing transcription factor critical for the regulation of nervous system development, transcriptionally represses EBF3 expression. However, human neurodevelopmental disorders related to EBF3 have not been reported. Here, we describe three individuals who are affected by global developmental delay, intellectual disability, and expressive speech disorder and carry de novo variants in EBF3. Associated features seen in these individuals include congenital hypotonia, structural CNS malformations, ataxia, and genitourinary abnormalities. The de novo variants affect a single conserved residue in a zinc finger motif crucial for DNA binding and are deleterious in a fly model. Our findings indicate that mutations in EBF3 cause a genetic neurodevelopmental syndrome and suggest that loss of EBF3 function might mediate a subset of neurologic phenotypes shared by ARX-related disorders, including intellectual disability, abnormal genitalia, and structural CNS malformations.

Rimal, H; Pokharel, A

Attention Deficit Hyperactivity Disorder is the most common neuro- developmental disorders of childhood characterized by the core symptoms including inattentiveness and distractibility and frequently involve impairments in executive functioning, increased impulsivity, and restlessness. Objective To find out the prevalence of Attention Deficit Hyperactivity Disorder among school aged children Presented to Pediatric clinic and also to investigate associated comorbidities. Method This study was conducted at Nobel Medical College Teaching Hospital, Biratnagar during April 2014 - March 2015. Attention Deficit Hyperactivity Disorder was diagnosed by the developmental Pediatrician after taking relevant history and the clinical assessment using Attention Deficit Hyperactivity Disorder rating scale with diagnostic criteria consistent with Diagnostic Statistical Manual - IV classification. Spence anxiety scale child and parent rated version and Strength and Difficulty Questionnaire were also used. Result Result showed the yearly prevalence of Attention Deficit Hyperactivity Disorder being 41(11.7%) with male: female ratio of 4:1. The study reported that Attention Deficit Hyperactivity Disorder combined type was the commonest type that was 26(63%) cases followed by Inattentive type 9(22%) cases and 6(15%) were hyperactive type. The mean age for Attention Deficit Hyperactivity Disorder was 7 years and 5 months. The most common co-morbidities were sleep problem 12(29.3%), Learning difficulty 10(24.4%), Anxiety disorder 10(24.4), Oppositional Defiant Disorder 9(22%), Autism Spectrum Disorder 5(12%), speech delay 6(14.6%), and 4(10%) had associated tics. There was abnormal SDQ prevalence of 29.3% across the area of emotional distress. The mean abnormal SDQ score in total difficulty area 8 (20.7%), socializing with peer 9(22%), behavioral difficulty 11(26.8%), hyperactivity/inattention 23(56.1%) and impact of difficulties in young person's life being 5(12.2%). Conclusion There is high prevalence of Attention Deficit Hyperactivity Disorder in children and adolescents in Nepal. This study has also looked at co-morbidities associated with Attention Deficit Hyperactivity Disorder and the findings of the study have thrown lights on the mental health and other developmental issues associated with it.

Toward a Neuroscience of Adult Cognitive Developmental Theory.

PubMed

Girgis, Fady; Lee, Darrin J; Goodarzi, Amir; Ditterich, Jochen

2018-01-01

Piaget's genetic epistemology has provided the constructivist approach upon which child developmental theories were founded, in that infants are thought to progress through distinct cognitive stages until they reach maturity in their early 20's. However, it is now well established that cognition continues to develop after early adulthood, and several "neo-Piagetian" theories have emerged in an attempt to better characterize adult cognitive development. For example, Kegan's Constructive Developmental Theory (CDT) argues that the thought processes used by adults to construct their reality change over time, and reaching higher stages of cognitive development entails becoming objectively aware of emotions and beliefs that were previously in the realm of the subconscious. In recent years, neuroscience has shown a growing interest in the biological substrates and neural mechanisms encompassing adult cognitive development, because psychological and psychiatric disorders can arise from deficiencies therein. In this article, we will use Kegan's CDT as a framework to discuss adult cognitive development in relation to closely correlated existing constructs underlying social processing, such as the perception of self and others. We will review the functional imaging and electrophysiologic evidence behind two key concepts relating to these posited developmental changes. These include self-related processing, a field that distinguishes between having conscious experiences ("being a self") and being aware of oneself having conscious experiences ("being aware of being a self"); and theory of mind, which is the objective awareness of possessing mental states such as beliefs and desires (i.e., having a "mind") and the understanding that others possess mental states that can be different from one's own. We shall see that cortical midline structures, including the medial prefrontal cortex and cingulate gyrus, as well as the temporal lobe, are associated with psychological tasks that test these models. In addition, we will review computational modeling approaches to cognitive development, and show how mathematical modeling can provide insights into how sometimes continuous changes in the neural processing substrate can give rise to relatively discrete developmental stages. Because deficiencies in adult cognitive development can result in disorders such as autism and depression, bridging the gaps between developmental psychology, neuroscience, and modeling has potential implications for clinical practice. As neuromodulation techniques such as deep brain and transcranial stimulation continue to advance, interfacing with these systems may lead to the emergence of novel investigational methods and therapeutic strategies in adults suffering from developmental disorders.

This study aimed to describe the demographic, social, developmental and behavioural profile of children hospitalised for alleged child maltreatment syndrome (CMS). This study was a retrospective review of the consecutive inpatient records of children (0-16 years) admitted to the National University Hospital, Singapore, for alleged CMS over a three-year period. Descriptive data on the demographic characteristics, alleged maltreatment, medical and developmental histories, and family background of these children were collected and analysed. Chi-square statistics were used to test whether family factors were associated with the type of maltreatment and the presence of developmental disorders. A total of 89 children, who accounted for 90 admission cases, were studied. Physical abuse (70.0%) was the most common, followed by neglect (11.1%) and sexual abuse (7.8%). Child protection services had already been involved in 29.2% of the cases prior to the child's admission. Children who were victims of abuse were more likely to come from homes with a prior history of domestic violence (p = 0.028). Financial difficulty was found to be a risk factor for neglect (p = 0.005). Among the 89 children, 15.7% were found to have developmental disorders and 10.1% had mental health diagnoses. Children who had developmental disorders were more likely to have a parent with a mental health disorder (p = 0.002). A sizeable proportion of the children admitted for alleged CMS had developmental or behavioural disorders. Clinicians have a role in ensuring that these children have appropriate follow-up plans. Children from high-risk families should be screened for maltreatment.

Biotinidase deficiency is the primary enzymatic defect in biotin-responsive, late-onset multiple carboxylase deficiency. Untreated children with profound biotinidase deficiency usually exhibit neurological symptoms including lethargy, hypotonia, seizures, developmental delay, sensorineural hearing loss and optic atrophy; and cutaneous symptoms including skin rash, conjunctivitis and alopecia. Although the clinical features of the disorder markedly improve or are prevented with biotin supplementation, some symptoms, once they occur, such as developmental delay, hearing loss and optic atrophy, are usually irreversible. To prevent development of symptoms, the disorder is screened for in the newborn period in essentially all states and in many countries. In order to better understand many aspects of the pathophysiology of the disorder, we have developed a transgenic biotinidase-deficient mouse. The mouse has a null mutation that results in no detectable serum biotinidase activity or cross-reacting material to antibody prepared against biotinidase. When fed a biotin-deficient diet these mice develop neurological and cutaneous symptoms, carboxylase deficiency, mild hyperammonemia, and exhibit increased urinary excretion of 3-hydroxyisovaleric acid and biotin and biotin metabolites. The clinical features are reversed with biotin supplementation. This biotinidase-deficient animal can be used to study systematically many aspects of the disorder and the role of biotinidase, biotin and biocytin in normal and in enzyme-deficient states.

Developmental dyscalculia.

PubMed

Shalev, Ruth S

2004-10-01

Developmental dyscalculia is a specific learning disability affecting the normal acquisition of arithmetic skills. Genetic, neurobiologic, and epidemiologic evidence indicates that dyscalculia, like other learning disabilities, is a brain-based disorder. However, poor teaching and environmental deprivation have also been implicated in its etiology. Because the neural network of both hemispheres comprises the substrate of normal arithmetic skills, dyscalculia can result from dysfunction of either hemisphere, although the left parietotemporal area is of particular significance. The prevalence of developmental dyscalculia is 5 to 6% in the school-aged population and is as common in girls as in boys. Dyscalculia can occur as a consequence of prematurity and low birthweight and is frequently encountered in a variety of neurologic disorders, such as attention-deficit hyperactivity disorder (ADHD), developmental language disorder, epilepsy, and fragile X syndrome. Developmental dyscalculia has proven to be a persisting learning disability, at least for the short term, in about half of affected preteen pupils. Educational interventions for dyscalculia range from rote learning of arithmetic facts to developing strategies for solving arithmetic exercises. The long-term prognosis of dyscalculia and the role of remediation in its outcome are yet to be determined.

Need For Long-Term Care in Children is Increasingly Caused by Disorders of Psychological Development. Changes in the Care Causing Diagnoses According to German Social Code (SGB XI) Between 2009-2014.

2018-05-22

There is an ongoing discussion on the increasing number of children with mental and developmental disorders, with some even needing long-term care according to the German Social Code XI. This study was performed to identify the main diagnoses justifying such care in children and to analyse their prevalence over time. The diagnoses justifying long-term care were evaluated using care assessments of Bavarian children and adolescents between 2009 to 2014 by the medical service of statutory health insurance. Over the years investigated, the percentage of assessments due to a mental and behavioural disorder rose significantly from 36.2 to 42.2%. Since 2012, the most common diagnose changed from Down's syndrome to pervasive developmental disorders with marked increase of also mixed specific developmental disorders. In new applications for nursing insurance services the proportion of pervasive developmental disorders rose gradually from 151 in 2010 to 254 in 2014. During the whole period of time, the overall care dependency in children seemed to be stable. These observations might rather be influenced by altered awareness of health and illness, increasing readiness to seek help with psychological or developmental impairments as well as changed diagnostic criteria than by a steady increase in affected individuals. © Georg Thieme Verlag KG Stuttgart · New York.

Dysregulated mTORC1-Dependent Translational Control: From Brain Disorders to Psychoactive Drugs

PubMed Central

Santini, Emanuela; Klann, Eric

2011-01-01

In the last decade, a plethora of studies utilizing pharmacological, biochemical, and genetic approaches have shown that precise translational control is required for long-lasting synaptic plasticity and the formation of long-term memory. Moreover, more recent studies indicate that alterations in translational control are a common pathophysiological feature of human neurological disorders, including developmental disorders, neuropsychiatric disorders, and neurodegenerative diseases. Finally, translational control mechanisms are susceptible to modification by psychoactive drugs. Taken together, these findings point to a central role for translational control in the regulation of synaptic function and behavior. PMID:22073033

The Preschool Language Scale, Fourth Edition (PLS-4; Zimmerman, Steiner, & Pond, 2002) was used to examine syntactic and semantic language skills in preschool children with autism spectrum disorders (ASD) to determine its suitability for use with this population. We expected that PLS-4 performance would be better in more intellectually able children and that receptive skills would be relatively more impaired than expressive abilities, consistent with previous findings in the area of vocabulary. Our sample consisted of 294 newly diagnosed preschool children with ASD. Children were assessed via a battery of developmental measures, including the PLS-4. As expected, PLS-4 scores were higher in more intellectually able children with ASD, and overall, expressive communication was higher than auditory comprehension. However, this overall advantage was not stable across nonverbal developmental levels. Expressive skills were significantly better than receptive skills at the youngest developmental levels, whereas the converse applied in children with more advanced development. The PLS-4 can be used to obtain a general index of early syntax and semantic skill in young children with ASD. Longitudinal data will be necessary to determine how the developmental relationship between receptive and expressive language skills unfolds in children with ASD.

Background Studies on autism have tended to focus either on those with intellectual disability (ie, those with intellectual quotient [IQ] under 70) or on the group that is referred to as “high-functioning”, that is, those with borderline, average or above average IQ. The literature on cognition and daily functioning in autism spectrum disorder combined specifically with borderline intellectual functioning (IQ 70–84) is limited. Methods From a representative group of 208 preschool children diagnosed with autism spectrum disorder, those 50 children in the group with borderline intellectual functioning at ages 4.5–6.5 years were targeted for follow-up at a median age of 10 years. A new cognitive test was carried out in 30 children. Parents were interviewed with a semi-structured interview together with the Vineland Adaptive Behavior Scales (n=41) and the Autism-Tics, attention-deficit/hyperactivity disorder (AD/HD) and other comorbidities inventory (A-TAC) (n=36). Results Most children of interviewed parents presented problems within several developmental areas. According to A-TAC and the clinical interview, there were high rates of attention deficits and difficulties with regulating activity level and impulsivity. Vineland Adaptive Behavior Scales composite scores showed that at school age, a majority of the children had declined since the previous assessment at ages between 4.5 and 6.5 years. Almost half the tested group had shifted in their IQ level, to below 70 or above 84. Conclusion None of the children assessed was without developmental/neuropsychiatric problems at school-age follow-up. The results support the need for comprehensive follow-up of educational, medical and developmental/neuropsychiatric needs, including a retesting of cognitive functions. There is also a need for continuing parent/family follow-up and support. PMID:29042781

The purpose of this study was to explore the relationships between attention deficit/hyperactivity disorder and developmental coordination disorder symptoms and writing performance in Japanese second grade students from regular classrooms. The second grade students (N=873) in Japanese public elementary schools participated in this study. We examined a variety of writing tasks, such as tracing, copying, handwriting (Hiragana and Katakana), and spelling (Hiragana, Katakana, and Kanji). We employed the Japanese version of the home form ADHD-rating scale (ADHD-RS) and the Japanese version of the Developmental Coordination Disorder Questionnaire (DCDQ-J) to assess the developmental characteristics of the participating children. Seven writing performance scores were submitted to a principal component analysis with a promax rotation, which yielded three composite scores (Spelling Accuracy, Tracing and Copying Accuracy, and Handwriting Fluency). A multiple regression analysis found that inattention predicted Spelling Accuracy and Handwriting Fluency and that hyperactive-impulsive predicted Handwriting Fluency. In addition, fine motor ability predicted Tracing and Copying Accuracy. The current study offered empirical evidence suggesting that developmental characteristics such as inattention and fine motor skill are related to writing difficulties in Japanese typical developing children.

Although "intellectual disability" has widely replaced the term "mental retardation", the debate as to whether this entity should be conceptualized as a health condition or as a disability has intensified as the revision of the World Health Organization (WHO)'s International Classification of Diseases (ICD) advances. Defining intellectual disability as a health condition is central to retaining it in ICD, with significant implications for health policy and access to health services. This paper presents the consensus reached to date by the WHO ICD Working Group on the Classification of Intellectual Disabilities. Literature reviews were conducted and a mixed qualitative approach was followed in a series of meetings to produce consensus-based recommendations combining prior expert knowledge and available evidence. The Working Group proposes replacing mental retardation with intellectual developmental disorders, defined as "a group of developmental conditions characterized by significant impairment of cognitive functions, which are associated with limitations of learning, adaptive behaviour and skills". The Working Group further advises that intellectual developmental disorders be incorporated in the larger grouping (parent category) of neurodevelopmental disorders, that current subcategories based on clinical severity (i.e., mild, moderate, severe, profound) be continued, and that problem behaviours be removed from the core classification structure of intellectual developmental disorders and instead described as associated features.

Macrocephaly, which is defined as a head circumference greater than or equal to + 2 standard deviations, is a feature commonly observed in children with developmental delay and/or autism spectrum disorder. Although PTEN is a well-known gene identified in patients with this syndromic presentation, other genes in the PI3K-AKT-mTOR signalling pathway have also recently been suggested to have important roles. The aim of this study is to characterise the mutation spectrum of this group of patients. We performed whole-exome sequencing of 21 patients with macrocephaly and developmental delay/autism spectrum disorder. Sources of genomic DNA included blood, buccal mucosa and saliva. Germline mutations were validated by Sanger sequencing, whereas somatic mutations were validated by droplet digital PCR. We identified ten pathogenic/likely pathogenic mutations in PTEN ( n  = 4), PIK3CA ( n  = 3), MTOR ( n  = 1) and PPP2R5D ( n  = 2) in ten patients. An additional PTEN mutation, which was classified as variant of unknown significance, was identified in a patient with a pathogenic PTEN mutation, making him harbour bi-allelic germline PTEN mutations. Two patients harboured somatic PIK3CA mutations, and the level of somatic mosaicism in blood DNA was low. Patients who tested positive for mutations in the PI3K-AKT-mTOR pathway had a lower developmental quotient than the rest of the cohort (DQ = 62.8 vs. 76.1, p = 0.021). Their dysmorphic features were non-specific, except for macrocephaly. Among the ten patients with identified mutations, brain magnetic resonance imaging was performed in nine, all of whom showed megalencephaly. We identified mutations in the PI3K-AKT-mTOR signalling pathway in nearly half of our patients with macrocephaly and developmental delay/autism spectrum disorder. These patients have subtle dysmorphic features and mild developmental issues. Clinically, patients with germline mutations are difficult to distinguish from patients with somatic mutations, and therefore, sequencing of buccal or saliva DNA is important to identify somatic mosaicism. Given the high diagnostic yield and the management implications, we suggest implementing comprehensive genetic testing in the PI3K-AKT-mTOR pathway in the clinical evaluation of patients with macrocephaly and developmental delay and/or autism spectrum disorder.

Development of the uncinate fasciculus: Implications for theory and developmental disorders.

Olson, Ingrid R; Von Der Heide, Rebecca J; Alm, Kylie H; Vyas, Govinda

2015-08-01

The uncinate fasciculus (UF) is a long-range white matter tract that connects limbic regions in the temporal lobe to the frontal lobe. The UF is one of the latest developing tracts, and continues maturing into the third decade of life. As such, individual differences in the maturational profile of the UF may serve to explain differences in behavior. Indeed, atypical macrostructure and microstructure of the UF have been reported in numerous studies of individuals with developmental and psychiatric disorders such as social deprivation and maltreatment, autism spectrum disorders, conduct disorder, risk taking, and substance abuse. The present review evaluates what we currently know about the UF's developmental trajectory and reviews the literature relating UF abnormalities to specific disorders. Additionally, we take a dimensional approach and critically examine symptoms and behavioral impairments that have been demonstrated to cluster with UF aberrations, in an effort to relate these impairments to our speculations regarding the functionality of the UF. We suggest that developmental disorders with core problems relating to memory retrieval, reward and valuation computation, and impulsive decision making may be linked to aberrations in uncinate microstructure.

We investigate the relations of early atypical characteristics (perinatal problems, developmental delay, and difficult temperament) and onset-age (as well as severity of) first major depressive disorder (MDD) and first internalizing disorder in a clinical sample of depressed children in Hungary. Participants were 371 children (ages 7-14) with MDD, and their biological mothers, recruited through multiple clinical sites. Diagnoses (via DSM-IV criteria) and onset dates of disorders were finalized "best estimate" psychiatrists, and based on multiple information sources. Mothers provided developmental data in a structured interview. Difficult temperament predicted earlier onset of MDD and first internalizing disorder, but its effect was ameliorated if the family was intact during early childhood. Further, the importance of difficult temperament decreased as a function of time. Perinatal problems and developmental delay did not impact onset ages of disorders, and none of the early childhood characteristics associated with MDD episode severity. Children with MDD may have added disadvantage of earlier onset if they had a difficult temperament in infancy. Because early temperament mirrors physiological reactivity and regulatory capacity, it can affect various areas of functioning related to psychopathology. Early caregiver stability may attenuate some adverse effects of difficult infant temperament.

Children with developmental speech disorders may have additional deficits in speech perception and/or short-term memory. To determine whether these are only transient developmental delays that can accompany the disorder in childhood or persist as part of the speech disorder, adults with a persistent familial speech disorder were tested on speech perception and short-term memory. Nine adults with a persistent familial developmental speech disorder without language impairment were compared with 20 controls on tasks requiring the discrimination of fine acoustic cues for word identification and on measures of verbal and nonverbal short-term memory. Significant group differences were found in the slopes of the discrimination curves for first formant transitions for word identification with stop gaps of 40 and 20 ms with effect sizes of 1.60 and 1.56. Significant group differences also occurred on tests of nonverbal rhythm and tonal memory, and verbal short-term memory with effect sizes of 2.38, 1.56 and 1.73. No group differences occurred in the use of stop gap durations for word identification. Because frequency-based speech perception and short-term verbal and nonverbal memory deficits both persisted into adulthood in the speech-impaired adults, these deficits may be involved in the persistence of speech disorders without language impairment.

Receptor tyrosine kinase mutations in developmental syndromes and cancer: two sides of the same coin

PubMed Central

McDonell, Laura M.; Kernohan, Kristin D.; Boycott, Kym M.; Sawyer, Sarah L.

2015-01-01

Receptor tyrosine kinases (RTKs) are a family of ligand-binding cell surface receptors that regulate a wide range of essential cellular activities, including proliferation, differentiation, cell-cycle progression, survival and apoptosis. As such, these proteins play an important role during development and throughout life; germline mutations in genes encoding RTKs cause several developmental syndromes, while somatic alterations contribute to the pathogenesis of many aggressive cancers. This creates an interesting paradigm in which mutation timing, type and location in a gene leads to different cell signaling and biological responses, and ultimately phenotypic outcomes. In this review, we highlight the roles of RTKs in developmental disorders and cancer. The multifaceted roles of these receptors, their genetic signatures and their signaling during developmental morphogenesis and oncogenesis are discussed. Additionally, we propose that comparative analysis of RTK mutations responsible for developmental syndromes may shed light on those driving tumorigenesis. PMID:26152202

Integrating genetic and toxicogenomic information for determining underlying susceptibility to developmental disorders.

2010-10-01

To understand the complex etiology of developmental disorders, an understanding of both genetic and environmental risk factors is needed. Human and rodent genetic studies have identified a multitude of gene candidates for specific developmental disorders such as neural tube defects (NTDs). With the emergence of toxicogenomic-based assessments, scientists now also have the ability to compare and understand the expression of thousands of genes simultaneously across strain, time, and exposure in developmental models. Using a systems-based approach in which we are able to evaluate information from various parts and levels of the developing organism, we propose a framework for integrating genetic information with toxicogenomic-based studies to better understand gene-environmental interactions critical for developmental disorders. This approach has allowed us to characterize candidate genes in the context of variables critical for determining susceptibility such as strain, time, and exposure. Using a combination of toxicogenomic studies and complementary bioinformatic tools, we characterize NTD candidate genes during normal development by function (gene ontology), linked phenotype (disease outcome), location, and expression (temporally and strain-dependent). In addition, we show how environmental exposures (cadmium, methylmercury) can influence expression of these genes in a strain-dependent manner. Using NTDs as an example of developmental disorder, we show how simple integration of genetic information from previous studies into the standard microarray design can enhance analysis of gene-environment interactions to better define environmental exposure-disease pathways in sensitive and resistant mouse strains. © Wiley-Liss, Inc.

Developmental psychopathology: Attention Deficit Hyperactivity Disorder (ADHD)

Schmidt, Sören; Petermann, Franz

2009-01-01

Background Attention Deficit/Hyperactivity Disorder (ADHD), formerly regarded as a typical childhood disorder, is now known as a developmental disorder persisting over the lifespan. Starting in preschool-age, symptoms vary depending on the age group affected. Method According to the variability of ADHD-symptoms and the heterogeneity of comorbid psychiatric disorders, a broad review of recent studies was performed. These findings were summarized in a developmental psychopathological model, documenting relevant facts on a timeline. Results Based on a genetic disposition and a neuropsychological deregulation, there is evidence for factors which persist across the lifespan, change age-dependently, or show validity in a specific developmental phase. Qualitative changes can be found for children in preschool-age and adults. Conclusion These differences have implications for clinical practice as they can be used for prevention, diagnostic proceedings, and therapeutic intervention as well as for planning future studies. The present article is a translated and modified version of the German article "Entwicklungspsychopathologie der ADHS", published in Zeitschrift für Psychiatrie, Psychologie und Psychotherapie, 56, 2008, S. 265-274.

2011-01-01

Background The current study sought to compare levels of overprotection and parenting stress reported by caregivers of children with disorders of sex development at four different developmental stages. Methods Caregivers (N = 59) of children with disorders of sex development were recruited from specialty clinics and were asked to complete the Parent Protection Scale and Parenting Stress Index/Short Form as measures of overprotective behaviors and parenting stress, respectively. Results Analyses of covariance (ANCOVAs) were conducted to examine differences between caregiver report of overprotection and parenting stress. Results revealed that caregivers of infants and toddlers exhibited more overprotective behaviors than caregivers of children in the other age groups. Further, caregivers of adolescents experienced significantly more parenting stress than caregivers of school-age children, and this effect was driven by personal distress and problematic parent-child interactions, rather than having a difficult child. Conclusions These results suggest that caregivers of children with disorders of sex development may have different psychosocial needs based upon their child's developmental stage and based upon the disorder-related challenges that are most salient at that developmental stage.

2015-07-01

We evaluated a parent-created video self-modeling (VSM) intervention to improve independence in an adolescent diagnosed with Intellectual Developmental Disorder (IDD) and Autism Spectrum Disorder (ASD). In a multiple baseline design across routines, a parent and her 17-year-old daughter created self-modeling videos of three targeted routines needed for independence in the community. The parent used a tablet device with a mobile app called "VideoTote" to produce videos of the daughter performing the targeted routines. The mobile app includes a 30-s tutorial about making modeling videos. The parent and daughter produced and watched a VSM scene prior to performing each of the three routines in an analogue community setting. The adolescent showed marked, immediate, and sustained improvements in performing each routine following the production and implementation of the VSM. Performance was found to generalize to the natural community setting. Results suggest that parents can use available technology to promote community independence for transition age individuals. © The Author(s) 2015.

A unifying perspective on personality pathology across the life span: Developmental considerations for the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders

2010-01-01

Proposed changes in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) include replacing current personality disorder (PD) categories on Axis II with a taxonomy of dimensional maladaptive personality traits. Most of the work on dimensional models of personality pathology, and on personality disorders per se, has been conducted on young and middle-aged adult populations. Numerous questions remain regarding the applicability and limitations of applying various PD models to early and later life. In the present paper, we provide an overview of such dimensional models and review current proposals for conceptualizing PDs in DSM-V. Next, we extensively review existing evidence on the development, measurement, and manifestation of personality pathology in early and later life focusing on those issues deemed most relevant for informing DSM-V. Finally, we present overall conclusions regarding the need to incorporate developmental issues in conceptualizing PDs in DSM-V and highlight the advantages of a dimensional model in unifying PD perspectives across the life span.

This study aimed to compare imitation skills in children with autism spectrum disorder, and age-matched typically developing children and children with developmental delay, as well as to examine the association between imitation skills, and receptive and expressive language development in children with autism spectrum disorder. Imitation skills in children with autism spectrum disorder (n=18), and age-matched children with developmental delay (n=15) and typically developing children (n= 16) were assessed using the Motor Imitation Scale and Imitation Battery, and the differences in mean imitation scores between the groups were examined. Receptive language and expressive language development in the children with autism spectrum disorder were assessed using the Turkish Communicative Development Inventory (TCDI), and their association with imitation scores was explored. The children with autism spectrum disorder had significantly lower imitation scores than the children with developmental delay and typically developing children; however, there wasn't a significant difference in imitation scores between the children with developmental delay and typically developing children. A significant association between imitation scores, and receptive and expressive language development was observed in the children with autism spectrum disorder. The present findings indicate that deficient imitation skills are a distinctive feature of children with autism spectrum disorder and that imitation skills play a crucial role in children's language development.

2015-10-01

Acute liver failure (ALF) in children is a rare condition that is often fatal without liver transplantation. The diagnostic work-up is complex, and the etiology is unidentified in up to half of patients, making decisions like therapeutic transplantation extremely difficult. We collected clinical, laboratory, and outcome data on all patients under 5 years of age who were admitted between January 2001 and December 2011 to King's College Hospital with ALF secondary to an inherited metabolic disease (IMD), a common cause of pediatric acute liver failure. Thirty-six of 127 children with ALF had a metabolic etiology: galactosemia (17); mitochondrial respiratory chain disorder (MRCD, 7); ornithine transcarbamylase (OTC) deficiency (4); tyrosinemia type 1 (4); Niemann-Pick disease type C (NPC, 3); and congenital disorder of glycosylation type 1b (1). Seven children died: MRCD (4) and NPC (3). Four children were transplanted: OTC deficiency (1) and MRCD (3). Fifteen of 25 children followed up showed evidence of developmental delay. IMD is the most common group of disorders in this age group; indeterminate cases may yet include undiagnosed metabolic disorders; the overall survival rate is good but largely depends on diagnosis, while developmental outcome of the surviving patients is less favorable. • Up to half of children with ALF may be undiagnosed. • IMD is a common cause of pediatric acute liver failure. What is New: • Initial diagnostic clues may be gathered from the child's age and laboratory parameters. • Survival of children with IMD-related ALF is good, but developmental outcome is less favorable. • In the future, novel sequencing methods will aid in the diagnosis of disorders in which therapeutic decisions depend upon.

Exposure to cigarette smoke during development is linked to neurodevelopmental delays and cognitive impairment including impulsivity, attention deficit disorder, and lower IQ. Utilizing a murine experimental model of "active" inhalation exposure to cigarette smoke spanning the entirety of gestation and through human third trimester equivalent hippocampal development [gestation day 1 (GD1) through postnatal day 21 (PD21)], we examined hippocampus proteome and metabolome alterations present at a time during which developmental cigarette smoke exposure (CSE)-induced behavioral and cognitive impairments are evident in adult animals from this model system. At six month of age, carbohydrate metabolism and lipid content in the hippocampus of adult offspring remained impacted by prior exposure to cigarette smoke during the critical period of hippocampal ontogenesis indicating limited glycolysis. These findings indicate developmental CSE-induced systemic glucose availability may limit both organism growth and developmental trajectory, including the capacity for learning and memory.

[Contemporary cognitive theories about developmental dyscalculia].

PubMed

Castro-Cañizares, D; Estévez-Pérez, N; Reigosa-Crespo, V

To analyze the current theories describing the cognitive mechanisms underlying developmental dyscalculia. The four most researched hypotheses concerning the cognitive deficits related to developmental dyscalculia, as well as experimental evidences supporting or refusing them are presented. The first hypothesis states that developmental dyscalculia is consequence of domain general cognitive deficits. The second hypothesis suggests that it is due to a failure in the development of specialized brain systems dedicated to numerosity processing. The third hypothesis asserts the disorder is caused by a deficit in accessing quantity representation through numerical symbols. The last hypothesis states developmental dyscalculia appears as a consequence of impairments in a generalized magnitude system dedicated to the processing of continuous and discrete magnitudes. None of the hypotheses has been proven more plausible than the rest. Relevant issues rose by them need to be revisited and answered in the light of new experimental designs. In the last years the understanding of cognitive disorders involved in developmental dyscalculia has remarkably increased, but it is nonetheless insufficient. Additional research is required in order to achieve a comprehensive cognitive model of numerical processing development and its disorders. This will improve the diagnostic precision and the effectiveness of developmental dyscalculia intervention strategies.

Despite its long and auspicious place in the history of psychiatry, dissociative identity disorder (DID) has been associated with controversy. This paper aims to examine the empirical data related to DID and outline the contextual challenges to its scientific investigation. The overview is limited to DID-specific research in which one or more of the following conditions are met: (i) a sample of participants with DID was systematically investigated, (ii) psychometrically-sound measures were utilised, (iii) comparisons were made with other samples, (iv) DID was differentiated from other disorders, including other dissociative disorders, (v) extraneous variables were controlled or (vi) DID diagnosis was confirmed. Following an examination of challenges to research, data are organised around the validity and phenomenology of DID, its aetiology and epidemiology, the neurobiological and cognitive correlates of the disorder, and finally its treatment. DID was found to be a complex yet valid disorder across a range of markers. It can be accurately discriminated from other disorders, especially when structured diagnostic interviews assess identity alterations and amnesia. DID is aetiologically associated with a complex combination of developmental and cultural factors, including severe childhood relational trauma. The prevalence of DID appears highest in emergency psychiatric settings and affects approximately 1% of the general population. Psychobiological studies are beginning to identify clear correlates of DID associated with diverse brain areas and cognitive functions. They are also providing an understanding of the potential metacognitive origins of amnesia. Phase-oriented empirically-guided treatments are emerging for DID. The empirical literature on DID is accumulating, although some areas remain under-investigated. Existing data show DID as a complex, valid and not uncommon disorder, associated with developmental and cultural variables, that is amenable to psychotherapeutic intervention.

A major challenge in understanding substance-use disorders lies in uncovering why some individuals become addicted when exposed to drugs, whereas others do not. Although genetic, developmental, and environmental factors are recognized as major contributors to a person's risk of becoming addicted, the neurobiological processes that underlie this vulnerability are still poorly understood. Imaging studies suggest that individual variations in key dopamine-modulated brain circuits, including circuits involved in reward, memory, executive function, and motivation, contribute to some of the differences in addiction vulnerability.

Interpersonal Stress Regulation and the Development of Anxiety Disorders: An Attachment-Based Developmental Framework

PubMed Central

Nolte, Tobias; Guiney, Jo; Fonagy, Peter; Mayes, Linda C.; Luyten, Patrick

2011-01-01

Anxiety disorders represent a common but often debilitating form of psychopathology in both children and adults. While there is a growing understanding of the etiology and maintenance of these disorders across various research domains, only recently have integrative accounts been proposed. While classical attachment history has been a traditional core construct in psychological models of anxiety, contemporary attachment theory has the potential to integrate neurobiological and behavioral findings within a multidisciplinary developmental framework. The current paper proposes a modern attachment theory-based developmental model grounded in relevant literature from multiple disciplines including social neuroscience, genetics, neuroendocrinology, and the study of family factors involved in the development of anxiety disorders. Recent accounts of stress regulation have highlighted the interplay between stress, anxiety, and activation of the attachment system. This interplay directly affects the development of social–cognitive and mentalizing capacities that are acquired in the interpersonal context of early attachment relationships. Early attachment experiences are conceptualized as the key organizer of a complex interplay between genetic, environmental, and epigenetic contributions to the development of anxiety disorders – a multifactorial etiology resulting from dysfunctional co-regulation of fear and stress states. These risk-conferring processes are characterized by hyperactivation strategies in the face of anxiety. The cumulative allostatic load and subsequent “wear and tear” effects associated with hyperactivation strategies converge on the neural pathways of anxiety and stress. Attachment experiences further influence the development of anxiety as potential moderators of risk factors, differentially impacting on genetic vulnerability and relevant neurobiological pathways. Implications for further research and potential treatments are outlined. PMID:21960962

Findings on face identity and facial emotion recognition in autism spectrum disorder (ASD) are inconclusive. Moreover, little is known about the developmental trajectory of face processing skills in ASD. Taking a developmental perspective, the aim of this study was to extend previous findings on face processing skills in a sample of adolescents and adults with ASD. N = 38 adolescents and adults (13-49 years) with high-functioning ASD and n = 37 typically developing (TD) control subjects matched for age and IQ participated in the study. Moreover, n = 18 TD children between the ages of 8 and 12 were included to address the question whether face processing skills in ASD follow a delayed developmental pattern. Face processing skills were assessed using computerized tasks of face identity recognition (FR) and identification of facial emotions (IFE). ASD subjects showed impaired performance on several parameters of the FR and IFE task compared to TD control adolescents and adults. Whereas TD adolescents and adults outperformed TD children in both tasks, performance in ASD adolescents and adults was similar to the group of TD children. Within the groups of ASD and control adolescents and adults, no age-related changes in performance were found. Our findings corroborate and extend previous studies showing that ASD is characterised by broad impairments in the ability to process faces. These impairments seem to reflect a developmentally delayed pattern that remains stable throughout adolescence and adulthood.

Purpose This study assessed medication use and associated costs among 8- and 15-yearold children with autism spectrum disorders (ASD) identified by the South Carolina Autism and Developmental Disabilities Monitoring (SCADDM) Network. Methods All Medicaid-eligible SCADDM-identified children with ASD from surveillance years 2006 and 2007 were included (n=263). Children were classified as ASD cases when documented behaviors consistent with the DSM-IV-TR criteria for autistic disorder, Asperger disorder, or pervasive developmental disorder- not otherwise specified (PDD-NOS) were present in health and education evaluation records. Medication and cost data were obtained by linking population-based and Medicaid data. Results All 263 SCADDM-identified children had Medicaid data available; 56% (n=147) had a prescription of any type, 40% (n=105) used psychotropic medication, and 20% (n=52) used multiple psychotropic classes over the study period. Common combinations were (1) attention deficit hyperactivity disorder (ADHD) medications and an antihypertensive, antidepressant or antipsychotic; and (2) antidepressants and an antipsychotic. Multiple psychotropic classes were more common among older children. Both the overall distribution of the number of prescription claims and medication costs varied significantly by age. Conclusions Results confirm that medication use in ASD, alone or in combination, is common, costly, and may increase with age. PMID:22153288

There is a body of evidence demonstrating comorbidity of motor and cognitive deficit in «idiopathic» developmental disorders. These associations are also found in developmental disorders secondary to monogenic disorders as in Neurofibromatosis type 1 for which the principal complication during childhood is learning disabilities. The comparison of motor impairment between developmental disorders either idiopathic or secondary as in NF1 could help us to better understand the cause of the combined language/motor deficit in these populations. The aim of this current study was to investigate motor impairment in children with NF1 for which oral language had been specified and then to compare the motors skills of the NF1 group to motor performance of children with Specific Language Disorder (SLD). Two groups of 49 children between 5 and 12years old were included and compared, the NF1 group and the SLD (Specific Language Disorder) group. Each child completed evaluation involving cognitive, language and motor assessment. In NF1 group, motor impairment was more frequent and more severe and concerned specifically balance rather than manual dexterity or ball skills, compared to a group of children with SLD. This motor impairment was independent of language status in the NF1 group. These results as well as other studies on the same topic could suggest that in NF1 children, fine motor skills impairment would be dependent on the existence of comorbidity with language disorders. Also, that gross motor skills impairment, and more precisely the balance deficit would be characteristic of NF1. This issue encourages studies of procedural learning that can involve the fronto-striatal or the fronto-cerebellar loops according to the type of motor tasks and the stage of learning.

Summary The vast majority of mental illnesses can be conceptualized as developmental disorders of neural interactions within the connectome, or developmental miswiring. The recent maturation of pediatric in vivo brain imaging is bringing within reach the identification of clinically meaningful brain-based biomarkers of developmental disorders. Even more auspicious, is the ability to study the evolving connectome throughout life, beginning in utero, which promises to move the field from topological phenomenology to etiological nosology. Here, we scope advances in pediatric imaging of the brain connectome as the field faces the challenge of unraveling developmental miswiring. We highlight promises while also providing a pragmatic review of the many obstacles ahead that must be overcome to significantly impact public health. PMID:25233316

We previously estimated that 42% of patients with severe developmental disorders carry pathogenic de novo mutations in coding sequences. The role of de novo mutations in regulatory elements affecting genes associated with developmental disorders, or other genes, has been essentially unexplored. We identified de novo mutations in three classes of putative regulatory elements in almost 8,000 patients with developmental disorders. Here we show that de novo mutations in highly evolutionarily conserved fetal brain-active elements are significantly and specifically enriched in neurodevelopmental disorders. We identified a significant twofold enrichment of recurrently mutated elements. We estimate that, genome-wide, 1-3% of patients without a diagnostic coding variant carry pathogenic de novo mutations in fetal brain-active regulatory elements and that only 0.15% of all possible mutations within highly conserved fetal brain-active elements cause neurodevelopmental disorders with a dominant mechanism. Our findings represent a robust estimate of the contribution of de novo mutations in regulatory elements to this genetically heterogeneous set of disorders, and emphasize the importance of combining functional and evolutionary evidence to identify regulatory causes of genetic disorders.

Exploring depressive personality traits in youth: origins, correlates, and developmental consequences.

PubMed

Rudolph, Karen D; Klein, Daniel N

2009-01-01

Research suggests that depressive personality (DP) disorder may represent a persistent, trait-based form of depression that lies along an affective spectrum ranging from personality traits to diagnosable clinical disorders. A significant gap in this area of research concerns the development of DP and its applicability to youth. The present research explored the construct of DP traits in youth. Specifically, this study examined the reliability, stability, and validity of the construct, potential origins of DP traits, and the developmental consequences of DP traits. A sample of 143 youth (mean age = 12.37 years, SD = 1.26) and their caregivers completed semistructured interviews and questionnaires on two occasions, separated by a 12-month interval. The measure of DP traits was reliable and moderately stable over time. Providing evidence of construct validity, DP traits were associated with a network of constructs, including a negative self-focus, high-negative and low-positive emotionality, and heightened stress reactivity. Moreover, several potential origins of DP traits were identified, including a history of family adversity, maternal DP traits, and maternal depression. Consistent with hypotheses regarding their developmental significance, DP traits predicted the generation of stress and the emergence of depression (but not nondepressive psychopathology) during the pubertal transition. Finally, depression predicted subsequent DP traits, suggesting a reciprocal process whereby DP traits heighten risk for depression, which then exacerbates these traits. These findings support the construct of DP traits in youth, and suggest that these traits may be a useful addition to developmental models of risk for youth depression.

Examining treatment adherence among parents of children with autism spectrum disorder.

Children with Autism Spectrum Disorder (ASD) participate in a variety of treatments, including medication, behavioral, alternative and developmental treatments. Parent adherence to these treatments is crucial for positive child outcomes. The current study: 1) Explored patterns of parent adherence across the full range of treatments that are prescribed to children with ASD and, 2) Examined whether parent demographics, parent treatment attitudes, and child ASD severity contribute to parents' adherence across ASD treatments. Questionnaires were distributed to parents of children with ASD in a southeastern state. Parents (N = 274) were included if they were parenting a child with ASD who was receiving treatment for ASD symptoms. Paired t-tests and multiple linear regression were used to assess the study aims. Adherence to medication treatment was significantly greater than adherence to behavioral, developmental, or alternative treatments (adjusted p-values 0.0006, 0.0030, 0.0006 respectively). Perceived family burden of a treatment was associated with lower adherence to medication, developmental, and alternative treatments. Finally, greater ASD severity was associated with lower adherence to alternative treatments. Overall, the independent variables accounted for more variance in adherence to medication and alternative treatments than in behavioral and developmental treatments. Parents' adherence to ASD treatment differs significantly by treatment type and is influenced by parental perceptions of the burden of treatment on the family. These findings highlight the importance of understanding and addressing the impact of ASD treatment regimens on family life. Copyright © 2015 Elsevier Inc. All rights reserved.

Triple X syndrome (47, XXX) occurs in approximately 1:1,000 female births and has a variable phenotype of physical and psychological features. Prenatal diagnosis rates of 47, XXX are increasing due to non-invasive prenatal genetic testing. Previous studies suggest that prenatal diagnosed females have better neurodevelopmental outcomes. This cross-sectional study describes diagnosis, physical features, medical problems, and neurodevelopmental features in a large cohort of females with 47, XXX. Evaluation included review of medical and developmental history, physical exam, cognitive, and adaptive testing. Medical and developmental features were compared between the prenatal and postnatal diagnosis groups using rate calculations and Fisher's exact test. Cognitive and adaptive tests scores were compared using t-tests. Seventy-four females age 6 months-24 years (mean 8.3 years) participated. Forty-four (59.5%) females were in the prenatal diagnosis group. Mean age of postnatal diagnosis was 5.9 years; developmental delay was the most common indication for postnatal genetic testing. Common physical features included hypertelorism, epicanthal folds, clinodactyly, and hypotonia. Medical problems included dental disorders (44.4%), seizure disorders (16.2%), genitourinary malformations (12.2%). The prenatal diagnosis group had higher verbal (P < 0.001), general ability index (P = 0.004), and adaptive functioning scores (P < 0.001). Rates of ADHD (52.2% vs. 45.5%, P = 0.77) and learning disabilities (39.1% vs. 36.3%, P = 1.00) were similar between the two groups. These findings expand on the phenotypic features in females with Triple X syndrome and support that prenatally ascertained females have better cognitive and functional outcomes. However, prenatally diagnosed females are still at risk for neurodevelopmental disorders.

Is the increase of hypomanic stages during adolescence related to gender and developmental tasks?

PubMed

Brand, Serge; Angst, Jules; Holsboer-Trachsler, Edith

2010-04-01

To detach themselves from their family of origin, adolescents need to develop proactive behaviour which includes increased risk-taking and novelty seeking. These behaviours may be attributable both to developmental issues and to hypomanic-like stages. Since there is a lack of research focusing on hypomania in adolescents, the aim of the study was to compare hypomania scores of adolescents with those of adult outpatients suffering from bipolar II disorders, and to investigate possible gender-related differences. One hundred and seven adolescents (mean age: 18 years) took part in the study; 60 of them indicated that they experienced intense romantic love; 47 were controls. Participants completed the Hypomania Check List, and data were compared with those of adult outpatients suffering from bipolar II disorders. Scores of adolescents in early-stage intense romantic love differed from those of adolescent controls, but not from those of outpatients suffering from a bipolar II disorder. Factor analyses revealed that both groups of adolescents displayed higher scores for the factor "irritable/risk-taking" hypomania. A gender-related pattern was found, with increased scores for female adolescents. Adolescents' developmental tasks surrounding experiences in social, psychosexual and substance use-related engagement may lead to temporary and gender-related hypomanic-like stages.

[Developmental amnesia in the premature infant].

2010-02-01

All types of memory disorders have been observed in children, although these reports are rare. Developmental amnesia selectively involves episodic daily life memory while semantic learning is respected and general intelligence is not affected. Daily life is severely disturbed by this cognitive disorder usually occurring after hypoxic ischemic injury with bilateral hippocampal atrophy on MRI. Memory disorders are underdiagnosed in at-risk patients and rarely reported. We report on a former small-for-gestational-age preterm infant with no obvious hypoxic event during perinatal life. The follow-up was normal until elementary school. He had to spend 2 years in 1st grade and exhibited some behavioral troubles. At the age of 9, he was suspected of suffering from dyspraxia and was referred to a pediatrics rehabilitation center. IQ and neuropsychological tests were administered and showed selective autobiographical memory impairment defining developmental amnesia. Despite a typical clinical presentation, brain MRI was normal, including the hippocampal area. This observation underlines the need for a prolonged follow-up until school age to assess the outcome of preterm infants. Otherwise, the evaluation will be limited to motor impairment. Particular attention should be paid to memory during the follow-up to avoid misdiagnoses and to plan and adapt these children's educational strategies. Copyright 2009 Elsevier Masson SAS.

Depression is an incapacitating disorder, which is often overlooked in preschool children. The aim of this study was to analyse the prevalence of depressive symptoms and co-occurring risk factors in a large, population-based sample of preschool children. All 653 children (of a total of 731) in a defined geographical area were assessed during the school-entry exam by community care paediatricians. In addition to clinical appraisal, parents filled out the Preschool Feelings Checklist, a 16-item screening instrument with good psychometric properties. The mean age was 6.2 years (range 5.0-7.6 years) and the sample included 344 boys and 305 girls. The prevalence of depressive symptoms of clinical relevance (total score ≥3) was 5.7% (37). There were no differences between boys and girls, and between younger (<6 years) and older (>6 years) children. Depressive symptoms were associated with parental separation and comorbid behavioural problems, but especially with developmental motor and speech problems and disorders. Migration to Germany had no influence. Depressive symptoms are common in preschool children and associated with developmental problems. Depression should be considered in children with speech and motor problems who are at special risk. Early detection and treatment are recommended.

Risk-related liabilities associated with the development of cannabis use disorders (CUDs) during adolescence and early adulthood are thought to be established well before the emergence of the index episode. In this study, internalizing and externalizing psychopathology from earlier developmental periods were evaluated as risk factors for CUDs during adolescence and early adulthood. Participants (N = 816) completed 4 diagnostic assessments between the ages 16 and 30, during which current and past CUDs were assessed as well as a full range of psychiatric disorders associated with internalizing and externalizing psychopathology domains. In unadjusted and adjusted time-to-event analyses, externalizing but not internalizing psychopathology from proximal developmental periods predicted subsequent CUD onset. A large proportion of adolescent and early adult cases, however, did not manifest any externalizing or internalizing psychopathology during developmental periods before CUD onset. Findings are consistent with the emerging view that externalizing disorders from proximal developmental periods are robust risk factors for CUDs. Although the identification of externalizing liabilities may aid in the identification of individuals at risk for embarking on developmental pathways that culminate in CUDs, such liabilities are an incomplete indication of overall risk.

Mutations in FBXL4 have recently been recognized to cause a mitochondrial disorder, with clinical features including early onset lactic acidosis, hypotonia, and developmental delay. FBXL4 sequence analysis was performed in 808 subjects suspected to have a mitochondrial disorder. In addition, 28 samples from patients with early onset of lactic acidosis, but without identifiable mutations in 192 genes known to cause mitochondrial diseases, were examined for FBXL4 mutations. Definitive diagnosis was made in 10 new subjects with a total of 7 novel deleterious variants; 5 null and 2 missense substitutions. All patients exhibited congenital lactic acidemia, most of them with severe encephalopathic presentation, and global developmental delay. Overall, FBXL4 defects account for at least 0.7% (6 out of 808) of subjects suspected to have a mitochondrial disorder, and as high as 14.3% (4 out of 28) in young children with congenital lactic acidosis and clinical features of mitochondrial disease. Including FBLX4 in the mitochondrial diseases panel should be particularly important for patients with congenital lactic acidosis. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Explanations of firesetting in mentally disordered offenders: a review of the literature.

PubMed

Tyler, Nichola; Gannon, Theresa A

2012-01-01

This paper reviews current explanations of firesetting in adult mentally disordered offenders. In particular, attention is given to contemporary research that has examined developmental and background characteristics, personality and associated traits, motivation for firesetting, neurobiological explanations, psychiatric diagnoses, and frequency of self-injurious behavior, including suicide. The likelihood of recidivism and associated risk factors is also considered. Evaluation of the existing research has highlighted that even though a significant proportion has been conducted with psychiatric populations, little is understood about firesetting by mentally disordered offenders. In addition, little research has been conducted that compares mentally disordered firesetters to both other mentally disordered offenders and non-mentally disordered offenders. Recommendations are made for future research to further develop knowledge of this behavior.

The goal of this statement was to review the available literature on surveillance, screening, evaluation, and management strategies and put forward a scientific statement that would comprehensively review the literature and create recommendations to optimize neurodevelopmental outcome in the pediatric congenital heart disease (CHD) population. A writing group appointed by the American Heart Association and American Academy of Pediatrics reviewed the available literature addressing developmental disorder and disability and developmental delay in the CHD population, with specific attention given to surveillance, screening, evaluation, and management strategies. MEDLINE and Google Scholar database searches from 1966 to 2011 were performed for English-language articles cross-referencing CHD with pertinent search terms. The reference lists of identified articles were also searched. The American College of Cardiology/American Heart Association classification of recommendations and levels of evidence for practice guidelines were used. A management algorithm was devised that stratified children with CHD on the basis of established risk factors. For those deemed to be at high risk for developmental disorder or disabilities or for developmental delay, formal, periodic developmental and medical evaluations are recommended. A CHD algorithm for surveillance, screening, evaluation, reevaluation, and management of developmental disorder or disability has been constructed to serve as a supplement to the 2006 American Academy of Pediatrics statement on developmental surveillance and screening. The proposed algorithm is designed to be carried out within the context of the medical home. This scientific statement is meant for medical providers within the medical home who care for patients with CHD. Children with CHD are at increased risk of developmental disorder or disabilities or developmental delay. Periodic developmental surveillance, screening, evaluation, and reevaluation throughout childhood may enhance identification of significant deficits, allowing for appropriate therapies and education to enhance later academic, behavioral, psychosocial, and adaptive functioning.

Varieties of preschool hyperactivity: multiple pathways from risk to disorder.

2005-03-01

In this paper we examine the characteristics of preschool attention deficit hyperactivity disorder (ADHD) from both mental disorder and developmental psychopathology points of view. The equivalence of preschool and school-aged hyperactivity as a behavioral dimension is highlighted together with the potential value of extending the use of the ADHD diagnostic category to the preschool period where these behaviours take an extreme and impairing form (assuming age appropriate diagnostic items and thresholds can be developed). At the same time, the importance of identifying pathways between risk and later ADHD is emphasized. Developmental discontinuity and heterogeneity are identified as major characteristics of these pathways. We argue that models that distinguish among different developmental types of early-emerging problems are needed. An illustrative taxonomy of four developmental pathways implicating preschool hyperactivity is presented to provide a framework for future research.

Developmental cognitive genetics: How psychology can inform genetics and vice versa

PubMed Central

Bishop, Dorothy V. M.

2006-01-01

Developmental neuropsychology is concerned with uncovering the underlying basis of developmental disorders such as specific language impairment (SLI), developmental dyslexia, and autistic disorder. Twin and family studies indicate that genetic influences play an important part in the aetiology of all of these disorders, yet progress in identifying genes has been slow. One way forward is to cut loose from conventional clinical criteria for diagnosing disorders and to focus instead on measures of underlying cognitive mechanisms. Psychology can inform genetics by clarifying what the key dimensions are for heritable phenotypes. However, it is not a one-way street. By using genetically informative designs, one can gain insights about causal relationships between different cognitive deficits. For instance, it has been suggested that low-level auditory deficits cause phonological problems in SLI. However, a twin study showed that, although both types of deficit occur in SLI, they have quite different origins, with environmental factors more important for auditory deficit, and genes more important for deficient phonological short-term memory. Another study found that morphosyntactic deficits in SLI are also highly heritable, but have different genetic origins from impairments of phonological short-term memory. A genetic perspective shows that a search for the underlying cause of developmental disorders may be misguided, because they are complex and heterogeneous and are associated with multiple risk factors that only cause serious disability when they occur in combination.

PurposeGiven the rapid pace of discovery in rare disease genomics, it is likely that improvements in diagnostic yield can be made by systematically reanalyzing previously generated genomic sequence data in light of new knowledge.MethodsWe tested this hypothesis in the United Kingdom-wide Deciphering Developmental Disorders study, where in 2014 we reported a diagnostic yield of 27% through whole-exome sequencing of 1,133 children with severe developmental disorders and their parents. We reanalyzed existing data using improved variant calling methodologies, novel variant detection algorithms, updated variant annotation, evidence-based filtering strategies, and newly discovered disease-associated genes.ResultsWe are now able to diagnose an additional 182 individuals, taking our overall diagnostic yield to 454/1,133 (40%), and another 43 (4%) have a finding of uncertain clinical significance. The majority of these new diagnoses are due to novel developmental disorder-associated genes discovered since our original publication.ConclusionThis study highlights the importance of coupling large-scale research with clinical practice, and of discussing the possibility of iterative reanalysis and recontact with patients and health professionals at an early stage. We estimate that implementing parent-offspring whole-exome sequencing as a first-line diagnostic test for developmental disorders would diagnose >50% of patients.GENETICS in MEDICINE advance online publication, 11 January 2018; doi:10.1038/gim.2017.246.

The First Year Inventory is a parent-report measure designed to identify 12-month-old infants at risk for autism spectrum disorder. First Year Inventory taps behaviors that indicate risk in the developmental domains of sensory-regulatory and social-communication functioning. This longitudinal study is a follow-up of 699 children at 3 years of age from a community sample whose parents completed the First Year Inventory when their children were 12 months old. Parents of all 699 children completed the Social Responsiveness Scale-Preschool version and the Developmental Concerns Questionnaire to determine age 3 developmental outcomes. In addition, children deemed at risk for autism spectrum disorder based on liberal cut points on the First Year Inventory, Social Responsiveness Scale-Preschool, and/or Developmental Concerns Questionnaire were invited for in-person diagnostic evaluations. We found 9 children who had a confirmed diagnosis of autism spectrum disorder from the sample of 699. Receiver operating characteristic analyses determined that a two-domain cutoff score yielded optimal classification of children: 31% of those meeting algorithm cutoffs had autism spectrum disorder and 85% had a developmental disability or concern by age 3. These results suggest that the First Year Inventory is a promising tool for identifying 12-month-old infants who are at risk for an eventual diagnosis of autism spectrum disorder.

Although “intellectual disability” has widely replaced the term “mental retardation”, the debate as to whether this entity should be conceptualized as a health condition or as a disability has intensified as the revision of the World Health Organization (WHO)’s International Classification of Diseases (ICD) advances. Defining intellectual disability as a health condition is central to retaining it in ICD, with significant implications for health policy and access to health services. This paper presents the consensus reached to date by the WHO ICD Working Group on the Classification of Intellectual Disabilities. Literature reviews were conducted and a mixed qualitative approach was followed in a series of meetings to produce consensus-based recommendations combining prior expert knowledge and available evidence. The Working Group proposes replacing mental retardation with intellectual developmental disorders, defined as “a group of developmental conditions characterized by significant impairment of cognitive functions, which are associated with limitations of learning, adaptive behaviour and skills”. The Working Group further advises that intellectual developmental disorders be incorporated in the larger grouping (parent category) of neurodevelopmental disorders, that current subcategories based on clinical severity (i.e., mild, moderate, severe, profound) be continued, and that problem behaviours be removed from the core classification structure of intellectual developmental disorders and instead described as associated features.

Only 20 patients with deletions of 18q12.2 have been reported in the literature and the associated phenotype includes borderline intellectual disability, behavioral problems, seizures, obesity, and eye manifestations. Here, we report a male patient with a de novo translocation involving chromosomes 12 and 18, with borderline IQ, developmental and behavioral disorders, myopia, obesity, and febrile seizures in childhood. We characterized the rearrangement with Affymetrix SNP 6.0 Array analysis and next-generation mate pair sequencing and found truncation of CELF4 at 18q12.2. This second report of a patient with a neurodevelopmental phenotype and a translocation involving CELF4 supports that CELF4 is responsible for the phenotype associated with deletion of 18q12.2. Our study illustrates the utility of high-resolution genome-wide techniques in identifying neurodevelopmental and neurobehavioral genes, and it adds to the growing evidence, including a transgenic mouse model, that CELF4 is important for human brain development.

Chiayi is a rural county located in southwestern Taiwan, and the effectiveness of its early intervention service system for autism spectrum disorders was studied in detail. A total of 71 children with autism spectrum disorders ( n = 35) and developmental delay ( n = 36) aged 2.5 years were referred from the only Early Intervention Reporting and Referral Center in Chiayi and followed up at 4 years. Results showed relatively low and varied services of early intervention for both groups during two time-point periods and a relative lack of specific early intervention programs for children with autism spectrum disorders. It was found, however, that cognitive abilities were increased for autism spectrum disorders and developmental delay groups. Additionally, the Early Learning Score at the initial evaluation could contribute to the high learner autism spectrum disorders subgroup. Parental socio-economic level was also determined to benefit the high learner developmental delay subgroup.

Exploration of developmental mechanisms classically relies on analysis of pattern regularities. Whether disorders induced by biological noise may carry information on building principles of developmental systems is an important debated question. Here, we addressed theoretically this question using phyllotaxis, the geometric arrangement of plant aerial organs, as a model system. Phyllotaxis arises from reiterative organogenesis driven by lateral inhibitions at the shoot apex. Motivated by recurrent observations of disorders in phyllotaxis patterns, we revisited in depth the classical deterministic view of phyllotaxis. We developed a stochastic model of primordia initiation at the shoot apex, integrating locality and stochasticity in the patterning system. This stochastic model recapitulates phyllotactic patterns, both regular and irregular, and makes quantitative predictions on the nature of disorders arising from noise. We further show that disorders in phyllotaxis instruct us on the parameters governing phyllotaxis dynamics, thus that disorders can reveal biological watermarks of developmental systems.

Discovery of most autosomal recessive disease genes has involved analysis of large, often consanguineous, multiplex families or small cohorts of unrelated individuals with a well-defined clinical condition. Discovery of novel dominant causes of rare, genetically heterogenous developmental disorders has been revolutionized by exome analysis of large cohorts of phenotypically diverse parent-offspring trios 1,2. Here we analysed 4,125 families with diverse, rare, genetically heterogeneous developmental disorders and identified four novel autosomal recessive disorders. These four disorders were identified by integrating Mendelian filtering (identifying probands with rare biallelic putatively damaging variants in the same gene) with statistical assessments of (i) the likelihood of sampling the observed genotypes from the general population, and (ii) the phenotypic similarity of patients with the same recessive candidate gene. This new paradigm promises to catalyse discovery of novel recessive disorders, especially those with less consistent or nonspecific clinical presentations, and those caused predominantly by compound heterozygous genotypes.

Background & objectives: The aetiology of mental retardation is varied and difficult to establish. Reports from India on the spectrum of underlying causative conditions are lacking. This retrospective study was conducted to establish the various aetiologies of mental retardation (MR) and developmental delay (DD) in patients attending a medical genetics centre in north India and to assess the contribution of genetic disorders. Methods: This retrospective study was conducted at a tertiary care centre in north India. All patients attending the centre with MR or DD from January 2007 to December 2009 were included. The aetiology of MR/DD was ascertained after clinical assessment and targeted laboratory evaluation. The spectrum of causative conditions and contribution of genetic disorders was established. Results: A total of 338 patients were included in the study, of whom definite diagnosis was established in 253 (74.8%). The various aetiological categories were: chromosomal disorders in 112 (33.1%), non chromosomal syndromes in 32 (9.5%), neurometabolic disorders in 34 (10.1%), central nervous system structural defects in 25 (7.4%), cerebral palsy in 43 (12.7%) and environmental insults in 7 (2%). Eighty five patients (25.2%) had idiopathic mental retardation. A total of 196 (58%) patients had a genetic disorder as the cause of MR/DD. Interpretation & conclusions: The aetiology of MR/DD is varied and difficult to establish in a significant proportion of patients. Chromosomal and various monogenic disorders contribute to a large number of MR/DD cases and hence a genetic work up is essential for all such patients. PMID:23041737

This cross-sectional study examined perceived access to services, quality of care, and family impact reported by caregivers of children aged 3-17 years with autism spectrum disorders, as compared to caregivers of children with other developmental disabilities and other mental health conditions. The 2009-2010 National Survey of Children with Special Health Care Needs was utilized to examine the association between child's special needs condition and three outcomes (N = 18,136): access to services (difficulty using services, difficulty getting referrals, lack of source of care, and inadequate insurance coverage), quality of care (lack of care coordination, lack of shared decision making, and no routine screening), and family impact (financial, employment, and time-related burden). Multivariate logistic regressions were performed to compare caregivers of children with autism spectrum disorders to caregivers of children with developmental disabilities (cerebral palsy, Down syndrome, developmental delay, or intellectual disability), mental health conditions (attention deficit hyperactivity disorder, anxiety, behavioral/conduct problems, or depression), or both developmental disabilities and mental health conditions. Caregivers of children with autism spectrum disorders were significantly more likely to report difficulty using services, lack of source of care, inadequate insurance coverage, lack of shared decision making and care coordination, and adverse family impact as compared to caregivers of children with developmental disabilities, mental health conditions, or both. © The Author(s) 2013.

Multiple complex developmental disorder (MCDD) is a well-defined and validated behavioural subtype of pervasive developmental disorder-not otherwise specified (PDD-NOS) and is thought to be associated with a higher risk of developing a schizophrenic spectrum disorder. The question was addressed whether patients with MCDD show the same psychophysiological abnormalities as seen in patients with schizophrenia. Smooth pursuit eye movement (pursuit gain and saccadic parameters) was measured in children with either MCDD (n=18) or autism (n=18), and in age- and IQ-matched controls (n=36), as well as in a group of adult patients with schizophrenia (n=14) and a group of adult controls (n=17). We found the expected effect of lower velocity gain and increased number of saccades in schizophrenic patients. Children with MCDD also showed a lower velocity gain compared to controls children. In contrast, velocity gain was similar in autistic subjects and controls. No differences for velocity gain were found in a direct comparison between MCDD and autism. Saccadic parameters were not significantly different from controls in either MCDD or autistic subjects. Children with MCDD, like schizophrenic adults, show a reduced velocity gain, which could indicate that schizophrenia spectrum disorders and MCDD share (at least to some degree) a common neurobiological background.

The treatment of bleeding disorders improved in the last decades. However, the effect of growing up with bleeding disorders on developmental, emotional, and social aspects is understudied. Therefore, this study assesses HRQOL, developmental milestones, and self-esteem in Dutch young adults (YA) with bleeding disorders compared to peers. Ninety-five YA (18-30 years) with bleeding disorders (78 men; mean 24.7 years, SD 3.5) and 17 women (mean 25.1 years, SD 3.8) participated and completed the Pediatric Quality of Life Inventory Young Adult version, the Course of Life Questionnaire, and the Rosenberg Self-Esteem Scale. Differences between patients with bleeding disorders and their peers, and between hemophilia severity groups, were tested using Mann-Whitney U tests. YA men with bleeding disorders report a slightly lower HRQOL on the total scale, physical functioning, and school/work functioning in comparison to healthy peers (small effect sizes). YA men with severe hemophilia report more problems on the physical functioning scale than non-severe hemophilia. YA men with bleeding disorders achieved more psychosexual developmental milestones than peers, but show a delay in 'paid jobs, during middle and/or high school.' A somewhat lower self-esteem was found in YA men with bleeding disorders in comparison to peers (small effect size). For YA women with bleeding disorders, no differences were found on any of the outcomes in comparison to peers. This study demonstrates some impairments in HRQOL and self-esteem in YA men with bleeding disorders. By monitoring HRQOL, problems can be identified early, especially with regard to their physical and professional/school functioning.

Non-speech oral motor treatment for children with developmental speech sound disorders.

PubMed

Lee, Alice S-Y; Gibbon, Fiona E

2015-03-25

Children with developmental speech sound disorders have difficulties in producing the speech sounds of their native language. These speech difficulties could be due to structural, sensory or neurophysiological causes (e.g. hearing impairment), but more often the cause of the problem is unknown. One treatment approach used by speech-language therapists/pathologists is non-speech oral motor treatment (NSOMT). NSOMTs are non-speech activities that aim to stimulate or improve speech production and treat specific speech errors. For example, using exercises such as smiling, pursing, blowing into horns, blowing bubbles, and lip massage to target lip mobility for the production of speech sounds involving the lips, such as /p/, /b/, and /m/. The efficacy of this treatment approach is controversial, and evidence regarding the efficacy of NSOMTs needs to be examined. To assess the efficacy of non-speech oral motor treatment (NSOMT) in treating children with developmental speech sound disorders who have speech errors. In April 2014 we searched the Cochrane Central Register of Controlled Trials (CENTRAL), Ovid MEDLINE (R) and Ovid MEDLINE In-Process & Other Non-Indexed Citations, EMBASE, Education Resources Information Center (ERIC), PsycINFO and 11 other databases. We also searched five trial and research registers, checked the reference lists of relevant titles identified by the search and contacted researchers to identify other possible published and unpublished studies. Randomised and quasi-randomised controlled trials that compared (1) NSOMT versus placebo or control; and (2) NSOMT as adjunctive treatment or speech intervention versus speech intervention alone, for children aged three to 16 years with developmental speech sound disorders, as judged by a speech and language therapist. Individuals with an intellectual disability (e.g. Down syndrome) or a physical disability were not excluded. The Trials Search Co-ordinator of the Cochrane Developmental, Psychosocial and Learning Problems Group and one review author ran the searches. Two review authors independently screened titles and abstracts to eliminate irrelevant studies, extracted data from the included studies and assessed risk of bias in each of these studies. In cases of ambiguity or information missing from the paper, we contacted trial authors. This review identified three studies (from four reports) involving a total of 22 children that investigated the efficacy of NSOMT as adjunctive treatment to conventional speech intervention versus conventional speech intervention for children with speech sound disorders. One study, a randomised controlled trial (RCT), included four boys aged seven years one month to nine years six months - all had speech sound disorders, and two had additional conditions (one was diagnosed as "communication impaired" and the other as "multiply disabled"). Of the two quasi-randomised controlled trials, one included 10 children (six boys and four girls), aged five years eight months to six years nine months, with speech sound disorders as a result of tongue thrust, and the other study included eight children (four boys and four girls), aged three to six years, with moderate to severe articulation disorder only. Two studies did not find NSOMT as adjunctive treatment to be more effective than conventional speech intervention alone, as both intervention and control groups made similar improvements in articulation after receiving treatments. One study reported a change in postintervention articulation test results but used an inappropriate statistical test and did not report the results clearly. None of the included studies examined the effects of NSOMTs on any other primary outcomes, such as speech intelligibility, speech physiology and adverse effects, or on any of the secondary outcomes such as listener acceptability.The RCT was judged at low risk for selection bias. The two quasi-randomised trials used randomisation but did not report the method for generating the random sequence and were judged as having unclear risk of selection bias. The three included studies were deemed to have high risk of performance bias as, given the nature of the intervention, blinding of participants was not possible. Only one study implemented blinding of outcome assessment and was at low risk for detection bias. One study showed high risk of other bias as the baseline characteristics of participants seemed to be unequal. The sample size of each of the included studies was very small, which means it is highly likely that participants in these studies were not representative of its target population. In the light of these serious limitations in methodology, the overall quality of the evidence provided by the included trials is judged to be low. Therefore, further research is very likely to have an important impact on our confidence in the estimate of treatment effect and is likely to change the estimate. The three included studies were small in scale and had a number of serious methodological limitations. In addition, they covered limited types of NSOMTs for treating children with speech sound disorders of unknown origin with the sounds /s/ and /z/. Hence, we judged the overall applicability of the evidence as limited and incomplete. Results of this review are consistent with those of previous reviews: Currently no strong evidence suggests that NSOMTs are an effective treatment or an effective adjunctive treatment for children with developmental speech sound disorders. Lack of strong evidence regarding the treatment efficacy of NSOMTs has implications for clinicians when they make decisions in relation to treatment plans. Well-designed research is needed to carefully investigate NSOMT as a type of treatment for children with speech sound disorders.

Gastrointestinal (GI) motility problems represent an important cause of morbidity and sometimes mortality in patients affected by developmental disorders. This article describes motility disorders in Down syndrome, cerebral palsy, familial dysautonomia, and Williams syndrome. These problems do not often receive appropriate attention, either because priority is given to other medical aspects of the disorder, or because of the inability of affected children to communicate their symptoms. A better approach to the diagnosis and treatment of GI disorders is required to improve quality of life and minimize morbidity and mortality among patients with developmental disorders.

Summary: Children in America today are at an unacceptably high risk of developing neurodevelopmental disorders that affect the brain and nervous system including autism, attention deficit hyperactivity disorder, intellectual disabilities, and other learning and behavioral disabilities. These are complex disorders with multiple causes—genetic, social, and environmental. The contribution of toxic chemicals to these disorders can be prevented. Approach: Leading scientific and medical experts, along with children’s health advocates, came together in 2015 under the auspices of Project TENDR: Targeting Environmental Neuro-Developmental Risks to issue a call to action to reduce widespread exposures to chemicals that interfere with fetal and children’s brain development. Based on the available scientific evidence, the TENDR authors have identified prime examples of toxic chemicals and pollutants that increase children’s risks for neurodevelopmental disorders. These include chemicals that are used extensively in consumer products and that have become widespread in the environment. Some are chemicals to which children and pregnant women are regularly exposed, and they are detected in the bodies of virtually all Americans in national surveys conducted by the U.S. Centers for Disease Control and Prevention. The vast majority of chemicals in industrial and consumer products undergo almost no testing for developmental neurotoxicity or other health effects. Conclusion: Based on these findings, we assert that the current system in the United States for evaluating scientific evidence and making health-based decisions about environmental chemicals is fundamentally broken. To help reduce the unacceptably high prevalence of neurodevelopmental disorders in our children, we must eliminate or significantly reduce exposures to chemicals that contribute to these conditions. We must adopt a new framework for assessing chemicals that have the potential to disrupt brain development and prevent the use of those that may pose a risk. This consensus statement lays the foundation for developing recommendations to monitor, assess, and reduce exposures to neurotoxic chemicals. These measures are urgently needed if we are to protect healthy brain development so that current and future generations can reach their fullest potential. PMID:27479987

Psychiatric disorders in childhood and adolescence, in particular attention deficit disorder or specific learning disorders like developmental dyslexia and developmental dyscalculia, affect academic performance and learning at school. Recent advances in neuroscientific research have incited an intensive debate both in the general public and in the field of educational and instructional science as well as to whether and to what extent these new findings in the field of neuroscience might be of importance for school-related learning and instruction. In this review, we first summarize neuroscientific findings related to the development of attention, working memory and executive functions in typically developing children and then evaluate their relevance for school-related learning. We present an overview of neuroimaging studies of specific learning disabilities such as developmental dyslexia and developmental dyscalculia, and critically discuss their practical implications for educational and teaching practice, teacher training, early diagnosis as well as prevention and disorder-specific therapy. We conclude that the new interdisciplinary field of neuroeducation cannot be expected to provide direct innovative educational applications (e.g., teaching methods). Rather, the future potential of neuroscience lies in creating a deeper understanding of the underlying cognitive mechanisms and pathomechanisms of learning processes and learning disorders.

Early life nutrition, epigenetics and programming of later life disease.

Vickers, Mark H

The global pandemic of obesity and type 2 diabetes is often causally linked to marked changes in diet and lifestyle; namely marked increases in dietary intakes of high energy diets and concomitant reductions in physical activity levels. However, less attention has been paid to the role of developmental plasticity and alterations in phenotypic outcomes resulting from altered environmental conditions during the early life period. Human and experimental animal studies have highlighted the link between alterations in the early life environment and increased risk of obesity and metabolic disorders in later life. This link is conceptualised as the developmental programming hypothesis whereby environmental influences during critical periods of developmental plasticity can elicit lifelong effects on the health and well-being of the offspring. In particular, the nutritional environment in which the fetus or infant develops influences the risk of metabolic disorders in offspring. The late onset of such diseases in response to earlier transient experiences has led to the suggestion that developmental programming may have an epigenetic component, as epigenetic marks such as DNA methylation or histone tail modifications could provide a persistent memory of earlier nutritional states. Moreover, evidence exists, at least from animal models, that such epigenetic programming should be viewed as a transgenerational phenomenon. However, the mechanisms by which early environmental insults can have long-term effects on offspring are relatively unclear. Thus far, these mechanisms include permanent structural changes to the organ caused by suboptimal levels of an important factor during a critical developmental period, changes in gene expression caused by epigenetic modifications (including DNA methylation, histone modification, and microRNA) and permanent changes in cellular ageing. A better understanding of the epigenetic basis of developmental programming and how these effects may be transmitted across generations is essential for the implementation of initiatives aimed at curbing the current obesity and diabetes crisis.

PUF60 encodes a nucleic acid-binding protein, a component of multimeric complexes regulating RNA splicing and transcription. In 2013, patients with microdeletions of chromosome 8q24.3 including PUF60 were found to have developmental delay, microcephaly, craniofacial, renal and cardiac defects. Very similar phenotypes have been described in six patients with variants in PUF60, suggesting that it underlies the syndrome. We report 12 additional patients with PUF60 variants who were ascertained using exome sequencing: six through the Deciphering Developmental Disorders Study and six through similar projects. Detailed phenotypic analysis of all patients was undertaken. All 12 patients had de novo heterozygous PUF60 variants on exome analysis, each confirmed by Sanger sequencing: four frameshift variants resulting in premature stop codons, three missense variants that clustered within the RNA recognition motif of PUF60 and five essential splice-site (ESS) variant. Analysis of cDNA from a fibroblast cell line derived from one of the patients with an ESS variants revealed aberrant splicing. The consistent feature was developmental delay and most patients had short stature. The phenotypic variability was striking; however, we observed similarities including spinal segmentation anomalies, congenital heart disease, ocular colobomata, hand anomalies and (in two patients) unilateral renal agenesis/horseshoe kidney. Characteristic facial features included micrognathia, a thin upper lip and long philtrum, narrow almond-shaped palpebral fissures, synophrys, flared eyebrows and facial hypertrichosis. Heterozygote loss-of-function variants in PUF60 cause a phenotype comprising growth/developmental delay and craniofacial, cardiac, renal, ocular and spinal anomalies, adding to disorders of human development resulting from aberrant RNA processing/spliceosomal function.

Toward a Neuroscience of Adult Cognitive Developmental Theory

Girgis, Fady; Lee, Darrin J.; Goodarzi, Amir; Ditterich, Jochen

2018-01-01

Piaget's genetic epistemology has provided the constructivist approach upon which child developmental theories were founded, in that infants are thought to progress through distinct cognitive stages until they reach maturity in their early 20's. However, it is now well established that cognition continues to develop after early adulthood, and several “neo-Piagetian” theories have emerged in an attempt to better characterize adult cognitive development. For example, Kegan's Constructive Developmental Theory (CDT) argues that the thought processes used by adults to construct their reality change over time, and reaching higher stages of cognitive development entails becoming objectively aware of emotions and beliefs that were previously in the realm of the subconscious. In recent years, neuroscience has shown a growing interest in the biological substrates and neural mechanisms encompassing adult cognitive development, because psychological and psychiatric disorders can arise from deficiencies therein. In this article, we will use Kegan's CDT as a framework to discuss adult cognitive development in relation to closely correlated existing constructs underlying social processing, such as the perception of self and others. We will review the functional imaging and electrophysiologic evidence behind two key concepts relating to these posited developmental changes. These include self-related processing, a field that distinguishes between having conscious experiences (“being a self”) and being aware of oneself having conscious experiences (“being aware of being a self”); and theory of mind, which is the objective awareness of possessing mental states such as beliefs and desires (i.e., having a “mind”) and the understanding that others possess mental states that can be different from one's own. We shall see that cortical midline structures, including the medial prefrontal cortex and cingulate gyrus, as well as the temporal lobe, are associated with psychological tasks that test these models. In addition, we will review computational modeling approaches to cognitive development, and show how mathematical modeling can provide insights into how sometimes continuous changes in the neural processing substrate can give rise to relatively discrete developmental stages. Because deficiencies in adult cognitive development can result in disorders such as autism and depression, bridging the gaps between developmental psychology, neuroscience, and modeling has potential implications for clinical practice. As neuromodulation techniques such as deep brain and transcranial stimulation continue to advance, interfacing with these systems may lead to the emergence of novel investigational methods and therapeutic strategies in adults suffering from developmental disorders.

A Drosophila model for fetal alcohol syndrome disorders: role for the insulin pathway

McClure, Kimberly D.; French, Rachael L.; Heberlein, Ulrike

2011-01-01

SUMMARY Prenatal exposure to ethanol in humans results in a wide range of developmental abnormalities, including growth deficiency, developmental delay, reduced brain size, permanent neurobehavioral abnormalities and fetal death. Here we describe the use of Drosophila melanogaster as a model for exploring the effects of ethanol exposure on development and behavior. We show that developmental ethanol exposure causes reduced viability, developmental delay and reduced adult body size. We find that flies reared on ethanol-containing food have smaller brains and imaginal discs, which is due to reduced cell division rather than increased apoptosis. Additionally, we show that, as in mammals, flies reared on ethanol have altered responses to ethanol vapor exposure as adults, including increased locomotor activation, resistance to the sedating effects of the drug and reduced tolerance development upon repeated ethanol exposure. We have found that the developmental and behavioral defects are largely due to the effects of ethanol on insulin signaling; specifically, a reduction in Drosophila insulin-like peptide (Dilp) and insulin receptor expression. Transgenic expression of Dilp proteins in the larval brain suppressed both the developmental and behavioral abnormalities displayed by ethanol-reared adult flies. Our results thus establish Drosophila as a useful model system to uncover the complex etiology of fetal alcohol syndrome. PMID:21303840

Background The Study to Explore Early Development (SEED) is designed to enhance knowledge of autism spectrum disorder characteristics and etiologies. Objective This paper describes the demographic profile of enrolled families and examines sociodemographic differences between children with autism spectrum disorder and children with other developmental problems or who are typically developing. Methods This multi-site case-control study used health, education, and birth certificate records to identify and enroll children aged 2–5 years into one of three groups: 1) cases (children with autism spectrum disorder), 2) developmental delay or disorder controls, or 3) general population controls. Study group classification was based on sampling source, prior diagnoses, and study screening tests and developmental evaluations. The child's primary caregiver provided demographic characteristics through a telephone (or occasionally face-to-face) interview. Groups were compared using ANOVA, chi-squared test, or multinomial logistic regression as appropriate. Results Of 2768 study children, sizeable proportions were born to mothers of non-White race (31.7%), Hispanic ethnicity (11.4%), and foreign birth (17.6%); 33.0% of households had incomes below the US median. The autism spectrum disorder and population control groups differed significantly on nearly all sociodemographic parameters. In contrast, the autism spectrum disorder and developmental delay or disorder groups had generally similar sociodemographic characteristics. Conclusions SEED enrolled a sociodemographically diverse sample, which will allow further, in-depth exploration of sociodemographic differences between study groups and provide novel opportunities to explore sociodemographic influences on etiologic risk factor associations with autism spectrum disorder and phenotypic subtypes.

Dale, Naomi; Sonksen, Patricia

2002-09-01

This study retrospectively investigated the developmental perspective of 69 children (40 males, 29 females) with 'potentially simple' congenital disorders of the peripheral visual system: development was examined in the context of degree of visual impairment. Developmental and visual assessments were carried out at 10 to 16 months (Time 1) and 27 to 54 months of age (Time 2). Participants were grouped according to (1) visual status: profound visual impairment (PVI), severe visual impairment (SVI); (2) developmental status on the Reynell-Zinkin scales. A majority of the sample showed normal development on all subscales (62% Time 1, 57% Time 2). Those with PVI were more developmentally vulnerable than SVI with a greater incidence of (1) uneven developmental profile at Time 1 (48% PVI, 16% SVI); (2) global learning difficulties at Time 2 (37% PVI, 0% SVI); (3) delay on individual subscales at Time 2 (p<0.02 PVI versus SVI); (4) deceleration (verbal comprehension 74% PVI, 24% SVI, sensorimotor understanding 70% PVI, 27% SVI); and (5) severe developmental setback (33% PVI, 7% SVI). Risk factors of visual level, age, and sex for poor developmental outcome in infants with visual impairment were established.

Joint attention revisited: Finding strengths among children with autism.

PubMed

Hurwitz, Sarah; Watson, Linda R

2016-07-01

Differences in joint attention are prominent for some children with autism and are often used as an indicator of the disorder. This study examined the joint attention competencies of young children with autism who demonstrated joint attention ability and compared them to children with developmental delays. A total of 40 children with autism and developmental delays were matched pairwise based on mental and chronological age. Videos of children engaging in play were coded for the frequency and forms (eye contact, gestures, affect, etc.) of joint attention. Additionally, concurrent language was compared among children with autism (N = 32) by their joint attention ability. Children with autism spectrum disorder entered into joint attention significantly less often than children with developmental delays, but once engaged used the forms of joint attention similarly. For the matched pairs, there were no differences in language, but the children with autism who used joint attention had significantly better language than children with autism who did not (even after controlling for mental age). There is a group of young children with autism who can use joint attention but do so at lower frequencies than children with developmental delays. Possible reasons include difficulty disengaging attention and limited intrinsic social motivation to share. Adult persistence is recommended to encourage joint attention. © The Author(s) 2015.

End-of-life decision-making for children with severe developmental disabilities: The parental perspective.

Zaal-Schuller, I H; de Vos, M A; Ewals, F V P M; van Goudoever, J B; Willems, D L

2016-01-01

The objectives of this integrative review were to understand how parents of children with severe developmental disorders experience their involvement in end-of-life decision-making, how they prefer to be involved and what factors influence their decisions. We searched MEDLINE, EMBASE, CINAHL and PsycINFO. The search was limited to articles in English or Dutch published between January 2004 and August 2014. We included qualitative and quantitative original studies that directly investigated the experiences of parents of children aged 0-18 years with severe developmental disorders for whom an end-of-life decision had been considered or made. We identified nine studies that met all inclusion criteria. Reportedly, parental involvement in end-of-life decision-making varied widely, ranging from having no involvement to being the sole decision-maker. Most parents preferred to actively share in the decision-making process regardless of their child's specific diagnosis or comorbidity. The main factors that influenced parents in their decision-making were: their strong urge to advocate for their child's best interests and to make the best (possible) decision. In addition, parents felt influenced by their child's visible suffering, remaining quality of life and the will they perceived in their child to survive. Most parents of children with severe developmental disorders wish to actively share in the end-of-life decision-making process. An important emerging factor in this process is the parents' feeling that they have to stand up for their child's interests in conversations with the medical team. Copyright © 2015 Elsevier Ltd.

Roles of mTOR Signaling in Brain Development.

PubMed

Lee, Da Yong

2015-09-01

mTOR is a serine/threonine kinase composed of multiple protein components. Intracellular signaling of mTOR complexes is involved in many of physiological functions including cell survival, proliferation and differentiation through the regulation of protein synthesis in multiple cell types. During brain development, mTOR-mediated signaling pathway plays a crucial role in the process of neuronal and glial differentiation and the maintenance of the stemness of neural stem cells. The abnormalities in the activity of mTOR and its downstream signaling molecules in neural stem cells result in severe defects of brain developmental processes causing a significant number of brain disorders, such as pediatric brain tumors, autism, seizure, learning disability and mental retardation. Understanding the implication of mTOR activity in neural stem cells would be able to provide an important clue in the development of future brain developmental disorder therapies.

Caregiver Strain and Sensory Features in Children with Autism Spectrum Disorder and other Developmental Disabilities

Caring for children with disabilities contributes to increased levels of parent stress, or caregiver strain. However, the potential relationship of sensory features to strain among caregivers of children with autism spectrum disorder (ASD) and other developmental disabilities (DD) is unknown. Sensory features include over-reactions, under-reactions, and unusual interests in sensations, which may negatively impact family functioning. This descriptive study confirmed three caregiver strain types (i.e., objective, subjective internalized, subjective externalized) and explored differences among ASD (n=71) and DD (n=36) groups, with the ASD group reporting higher levels. Furthermore, this study explored the contribution of sensory features to caregiver strain, finding differential contributions to strain in the ASD group and covariate contributions (i.e., child cognition, mother’s education) in the DD group.

Post-traumatic stress disorder diagnosis in children: challenges and promises

Children and adolescents experience high rates of potentially traumatic experiences. Many children subsequently develop mental health problems, including post-traumatic stress disorder (PTSD) symptoms. Accurately diagnosing PTSD in children is challenging. This paper reviews the following important issues: (i) the specificity of the PTSD diagnosis; (ii) children who are symptomatic and impaired but do not have enough symptoms for the diagnosis of PTSD; (iii) developmental considerations for preschool and schooi-age children; and (iv) a variety of assessment challenges that reflect the difficulty and complexity of interviewing children and caregivers about these symptoms. Despite these challenges, PTSD remains the best construct for clinical and research work with trauma survivors. Pediatric PTSD criteria are valuable for identifying children at risk and in need of treatment and can be even more helpful when developmentally modified in ways that are discussed. PMID:19432391

Quantifying social development in autism.

This study was concerned with the development of quantitative measures of social development in autism. Multiple regression equations predicting social, communicative, and daily living skills on the Vineland Adaptive Behavior Scales were derived from a large, normative sample and applied to groups of autistic and nonautistic, developmentally disordered children. Predictive models included either mental or chronological age and other relevant variables. Social skills in the autistic group were more than two standard deviations below those predicted by their mental age; an index derived from the ratio of actual to predicted social skills correctly classified 94% of the autistic and 92% of the nonautistic, developmentally disordered cases. The findings are consistent with the idea that social disturbance is central in the definition of autism. The approach used in this study has potential advantages for providing more precise measures of social development in autism.

Redox Regulation and the Autistic Spectrum: Role of Tryptophan Catabolites, Immuno-inflammation, Autoimmunity and the Amygdala

PubMed Central

Anderson, George; Maes, Michael

2014-01-01

The autistic spectrum disorders (ASD) form a set of multi-faceted disorders with significant genetic, epigenetic and environmental determinants. Oxidative and nitrosative stress (O&NS), immuno-inflammatory pathways, mitochondrial dysfunction and dysregulation of the tryptophan catabolite (TRYCATs) pathway play significant interactive roles in driving the early developmental etiology and course of ASD. O&NS interactions with immuno-inflammatory pathways mediate their effects centrally via the regulation of astrocyte and microglia responses, including regional variations in TRYCATs produced. Here we review the nature of these interactions and propose an early developmental model whereby different ASD genetic susceptibilities interact with environmental and epigenetic processes, resulting in glia biasing the patterning of central interarea interactions. A role for decreased local melatonin and N-acetylserotonin production by immune and glia cells may be a significant treatment target. PMID:24669209

Comorbidity of Anxiety and Depression in Children and Adolescents: 20 Years After

Cummings, Colleen M.; Caporino, Nicole E.; Kendall, Philip C.

2014-01-01

Brady and Kendall (1992) concluded that although anxiety and depression in youth are meaningfully linked, there are important distinctions, and additional research was needed. Since then, studies of anxiety-depression comorbidity in youth have increased exponentially. Following a discussion of comorbidity, we review existing conceptual models and propose a multiple pathways model to anxiety-depression comorbidity. Pathway 1 describes youth with a diathesis for anxiety, with subsequent comorbid depression resulting from anxiety-related impairment. Pathway 2 refers to youth with a shared diathesis for anxiety and depression, who may experience both disorders simultaneously. Pathway 3 describes youth with a diathesis for depression, with subsequent comorbid anxiety resulting from depression-related impairment. Additionally, shared and stratified risk factors contribute to the development of the comorbid disorder, either by interacting with disorder-related impairment or by predicting the simultaneous development of the disorders. Our review addresses descriptive and developmental factors, gender differences, suicidality, assessments, and treatment-outcome research as they relate to comorbid anxiety and depression, and to our proposed pathways. Research since 1992 indicates that comorbidity varies depending on the specific anxiety disorder, with Pathway 1 describing youth with either social phobia or separation anxiety disorder and subsequent depression, Pathway 2 applying to youth with co-primary generalized anxiety disorder and depression, and Pathway 3 including depressed youth with subsequent social phobia. The need to test the proposed multiple pathways model and to examine (a) developmental change and (b) specific anxiety disorders is highlighted. PMID:24219155

Purpose to analyze and classify the spelling performance according to the semiology of spelling error of children with developmental dyslexia (DD) and with developmental dyslexia associated to attention deficit disorder and hyperactivity(DD and ADHD) comparing them to a group of children without learning process complaints. Methods Seventy students, from the third to fifth grade, participated in this study divided as follows: 32 children without complaints of learning difficulties (GI), mean age 9.5 years; 22 students with developmental dyslexia (GII), mean age 10 years; 16 scholars with developmental dyslexia associated to attention deficit disorders and hyperactivity (GIII), mean age 9.9. Spelling skills were assessed through a standardized word dictation task. Results Data indicated that GII and GIII children presented lower performance when compared with typically developed children. There was no statistical difference between the performance of GII and GIII children regarding the score reached in spelling, although GIII children presented the lowest performance. We observed differences between GII and GIII only in the type of misspelling. Conclusion Data from this research contribute to develop better programs for intervention in the studied population.

Developmental coordination disorder (DCD) is a heterogeneous disorder, which is often co-morbid with learning disabilities. However, mathematical problems have rarely been studied in DCD. The aim of this study was to investigate the mathematical problems in children with various degrees of motor problems. Specifically, this study explored if the development of mathematical skills in children with DCD is delayed or deficient. Children with DCD performed significantly worse for number fact retrieval and procedural calculation in comparison with age-matched control children. Moreover, children with mild DCD differed significantly from children with severe DCD on both number fact retrieval and procedural calculation. In addition, we found a developmental delay of 1 year for number fact retrieval in children with mild DCD and a developmental delay of 2 years in children with severe DCD. No evidence for a mathematical deficit was found. Diagnostic implications are discussed. Copyright © 2012 Elsevier Ltd. All rights reserved.

Diagnosis, treatment, and neurobiology of autism in children.

PubMed

Lainhart, J E; Piven, J

1995-08-01

Autism is a developmental neuropsychiatric disorder defined by the presence of social and communicative deficits, restricted and repetitive behaviors and interests, and a characteristic course. Research suggests that hereditary factors play a principal role in the etiology of most cases. A phenotype broader than autism, including milder social and language-based cognitive deficits, appears to be inherited. Although the pathogenesis is unknown, neurobiologic mechanisms clearly underlie the disorder. Neuropathologic studies have demonstrated abnormalities in limbic structures, the cerebellum, and the cortex. New advances in behavioral therapies and pharmacologic treatment are important components of successful multidisciplinary treatment of this disorder.

Screening accuracy of the parent-completed Ages and Stages Questionnaires - second edition as a broadband screener for motor problems in preschoolers with autism spectrum disorders.

Children with autism spectrum disorders are at risk for motor problems. However, this area is often overlooked in the developmental evaluation in autism diagnostic clinics. An alternative can be to identify children who should receive intensive motor assessment by using a parent-based screener. The aim of this study was to examine whether the Ages and Stages Questionnaires - second edition may be used to identify gross and fine motor problems in children. High-functioning children with autism spectrum disorder (n = 43, 22-54 m) participated in this study. Sensitivity, specificity, predictive values and areas under the receiver operating characteristic curve were calculated by comparing the Ages and Stages Questionnaires - second edition scores to the developmental evaluation of the Peabody Developmental Motor Scale - second edition. The results revealed that both the Ages and Stages Questionnaires - second edition gross and fine motor domain may be used to identify children without motor problems. In contrast, sensitivity analyses revealed the likelihood of under screening motor problems in this population. The Ages and Stages Questionnaires - second edition met only the criteria of a fair to good accuracy to identify poor gross motor (sensitivity = 100%) and below-average fine motor development (sensitivity = 71%) in this sample. Hence, the capacity of the Ages and Stages Questionnaires - second edition to identify motor problems in preschoolers with autism spectrum disorder appears to be limited. It is recommended to include a formal standardized motor test in the diagnostic procedure for all children with autism spectrum disorder. © The Author(s) 2016.

Whole-exome sequencing has transformed gene discovery and diagnosis in rare diseases. Translation into disease-modifying treatments is challenging, particularly for intellectual developmental disorder. However, the exception is inborn errors of metabolism, since many of these disorders are responsive to therapy that targets pathophysiological features at the molecular or cellular level. To uncover the genetic basis of potentially treatable inborn errors of metabolism, we combined deep clinical phenotyping (the comprehensive characterization of the discrete components of a patient's clinical and biochemical phenotype) with whole-exome sequencing analysis through a semiautomated bioinformatics pipeline in consecutively enrolled patients with intellectual developmental disorder and unexplained metabolic phenotypes. We performed whole-exome sequencing on samples obtained from 47 probands. Of these patients, 6 were excluded, including 1 who withdrew from the study. The remaining 41 probands had been born to predominantly nonconsanguineous parents of European descent. In 37 probands, we identified variants in 2 genes newly implicated in disease, 9 candidate genes, 22 known genes with newly identified phenotypes, and 9 genes with expected phenotypes; in most of the genes, the variants were classified as either pathogenic or probably pathogenic. Complex phenotypes of patients in five families were explained by coexisting monogenic conditions. We obtained a diagnosis in 28 of 41 probands (68%) who were evaluated. A test of a targeted intervention was performed in 18 patients (44%). Deep phenotyping and whole-exome sequencing in 41 probands with intellectual developmental disorder and unexplained metabolic abnormalities led to a diagnosis in 68%, the identification of 11 candidate genes newly implicated in neurometabolic disease, and a change in treatment beyond genetic counseling in 44%.

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by deficits in cognitive and emotional self-control. Optical technique acquisitions, such as near infrared spectroscopy (NIRS), seem to be very promising during developmental ages, as they are non- invasive techniques and less influenced by body movements than other neuroimaging methods. Recently, these new techniques are being widely used to measure neural correlates underlying neuropsychological deficits in children with ADHD. In a short series of articles, we will review the results of functional NIRS (fNIRS) studies in children with ADHD. The present brief review will focus on the results of the fNIRS studies that investigate cortical activity during neuropsychological and/or emotional tasks. According to the reviewed studies, children and adolescents with ADHD show peculiar cortical activation both during neurological and emotional tasks, and the majority of the reviewed studies revealed lower prefrontal cortex activation in patients compared to typically developmental controls. a consistent interpretation of these results is limited by the substantial methodological heterogeneity including patients' medication status and washout period, explored cerebral regions, neuropsychological tasks, number of channels and sampling temporal resolutions. fNIRS seems to be a promising tool for investigating neural substrates of emotional dysregulation and executive function deficits in individuals with ADHD during developmental ages.

Psychomotor development and psychopathology in childhood.

PubMed

de Raeymaecker, Dirk M J

2006-01-01

The sensorimotor developmental phase, leading to a gradual acquisition of skilled actions, is of crucial importance for the young child and its growing sense of competence. Three vital steps in motor development are mentioned: first, the smooth and spontaneous movements of the "graceful and elegant" baby, expression of his well-being and vitality, with their profound effect on the mother-infant relationship; second, the emergence of intentional and goal-oriented acts leading to Funktionslust and playful repetitions; and finally, the development of symbolic acts and increasing technical capacity to use playthings in imaginative play. The psychodynamic significance of the most important motor milestones for the child's ego development is set out. Motility is one of the most important avenues for exercising such functions as mastery, integration, reality testing (self-preservation), and control of impulses. One may consider this early childhood period of rapid motor development as the motor phase of ego and libido development. Hence, many forms of developmental psychopathology are attended with motor impairment or insufficient motor mastery and integration. From that clinical perspective pass in review: perinatal complications and motor disturbance, attention deficit/hyperactivity disorder, dissociated motor development, low birth weight children and their developmental difficulties, developmental coordination disorder, aspects of pervasive developmental disorder, and stereotypic movement disorder.

Pike, M G; Jan, J E; Wong, P K

1989-06-01

Ninety-seven children who were born between 1954 and 1986 and presented to the Visually Impaired Program of British Columbia's Children's Hospital, Vancouver, Canada, with a primary ophthalmologic diagnosis of cataracts, were assessed neurologically, ophthalmologically, audiologically, and developmentally. Causal factors included prenatal infection (35 cases), hereditary cataracts (22 cases), various syndromes and metabolic disorders (9 cases), trauma (1 case), and unknown (30 cases). Ninety children were diagnosed to have congenital cataracts while 7 acquired them. Findings indicated that prenatal infection continues to be a cause of infantile cataracts, despite rubella immunization; that prematurity is not, as has been stated in the past, a cause of infantile cataract; and that careful neurological, audiological, and developmental examination is vital in the assessment of likely causes of this condition.

Sleep in Neurodevelopmental Disorders

Esbensen, Anna J; Schwichtenberg, Amy J

2017-01-01

Individuals with intellectual and developmental disabilities (IDD) experience sleep problems at higher rates than the general population. Although individuals with IDD are a heterogeneous group, several sleep problems cluster within genetic syndromes or disorders. This review summarizes the prevalence of sleep problems experienced by individuals with Angelman syndrome, Cornelia de Lange syndrome, Cri du Chat syndrome, Down syndrome, fragile X syndrome, Prader-Willi syndrome, Smith-Magenis syndrome, Williams syndrome, autism spectrum disorder, and idiopathic IDD. Factors associated with sleep problems and the evidence for sleep treatments are reviewed for each neurodevelopmental disorder. Sleep research advancements in neurodevelopmental disorders are reviewed, including the need for consistency in defining and measuring sleep problems, considerations for research design and reporting of results, and considerations when evaluating sleep treatments.

Deficits in motor abilities and developmental fractionation of imitation performance in high-functioning autism spectrum disorders.

PubMed

Biscaldi, Monica; Rauh, Reinhold; Irion, Lisa; Jung, Nikolai H; Mall, Volker; Fleischhaker, Christian; Klein, Christoph

2014-07-01

The co-occurrence of motor and imitation disabilities often characterises the spectrum of deficits seen in patients with autism spectrum disorders (ASD). Whether these seemingly separate deficits are inter-related and whether, in particular, motor deficits contribute to the expression of imitation deficits is the topic of the present study and was investigated by comparing these deficits' cross-sectional developmental trajectories. To that end, different components of motor performance assessed in the Zurich Neuromotor Assessment and imitation abilities for facial movements and non-meaningful gestures were tested in 70 subjects (aged 6-29 years), including 36 patients with high-functioning ASD and 34 age-matched typically developed (TD) participants. The results show robust deficits in probands with ASD in timed motor performance and in the quality of movement, which are all independent of age, with one exception. Only diadochokinesis improves moderately with increasing age in ASD probands. Imitation of facial movements and of non-meaningful hand, finger, hand finger gestures not related to social context or tool use is also impaired in ASD subjects, but in contrast to motor performance this deficit overall improves with age. A general imitation factor, extracted from the highly inter-correlated imitation tests, is differentially correlated with components of neuromotor performance in ASD and TD participants. By developmentally fractionating developmentally stable motor deficits from developmentally dynamic imitation deficits, we infer that imitation deficits are primarily cognitive in nature.

Reported History of Developmental Regression and Restricted, Repetitive Behaviors in Children with Autism Spectrum Disorders.

2016-01-01

Previous research on developmental regression in youth with autism spectrum disorders (ASD) has often been limited by the definition, assessment, and methodology used to evaluate and describe regression. This study sought to overcome these limitations by examining the prevalence, timing, and correlates of documented cases of developmental regression in a large, epidemiological sample of youth with ASD. Utilizing a population-based surveillance methodology, this study includes 862 youth with ASD identified through abstraction and clinician record review. Approximately 21% of the sample had developmental regression documented in their medical or educational records with the mean age of regression being 24.2 ± 14.3 months. Youth with ASD and a history of regression were more likely to have comorbid intellectual disability, a prior community diagnosis of ASD, and be eligible for educational services as a student with autism. Youth with a documented history of regression also had higher rates of restricted, repetitive behaviors, such as stereotyped speech, nonfunctional routines/rituals, and sensory interests. Results suggest that youth with a history of regression are not only more likely to have comorbid intellectual disability but are also are more likely to have been previously diagnosed with ASD in the community, suggesting that development regression may play an important role in identifying children who are at the risk for ASD and need evaluation. Higher rates of restricted, repetitive behaviors in youth with a documented history of regression may also provide important insights into the relationship between ASD and developmental regression.

When Norman Geschwind (1926-1984) attended medical school in the 1940s, his psychiatry professors taught as if behavior were unrelated to neuropathology. The focus of neurology remained the diagnosis and treatment of aphasias and epilepsies, while cognitive impairments and developmental disorders were classified as functional (psychological) disorders. Geschwind was troubled by the fact that many of the patients he saw with neurological deficits also presented with behavioral (developmental) disorders. Geschwind's generation also had been taught that aphasias resulted from global rather than localized or focal neurological lesions. These holists, including the prepsychoanalytic Sigmund Freud, targeted the work of aphasiologist Carl Wernicke as an exemplar of the flaws of the localizationist hypothesis. Reading Wernicke in the original, Geschwind discovered a complex and multilayered explanation for aphasias that implicated lesions located in association pathways that, when extensive, resulted in behavioral disorders. Geschwind also reread the works of the holists, discovering that, while their rhetoric rejected Wernicke, their explanations of aphasias actually reinforced Wernicke's hypothesis. Building on his reading of these historical documents and his clinical experiences, Geschwind urged the resurrection of Wernicke's disconnection syndromes that Geschwind labeled as Behavioral Neurology.
