Learning to read is very challenging for children with Autism Spectrum Disorders (ASD), but also very important, as it can give them access to new knowledge. This is even more challenging in minimally verbal children, who do not have the verbal abilities to learn through usual methods. To address the learning of literacy skills in French minimally verbal school-aged children with ASD, we designed the serious game SEMA-TIC, which relies on non-verbal cognitive skills and uses specific learning strategies adapted to the features of autistic individuals...

OBJECTIVE: Pediatric Acute Neuropsychiatric Syndrome (PANS) and pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) are conditions marked by sudden onset of obsessive-compulsive disorder (OCD), tics, or avoidant/restrictive food intake in combination with multiple psychiatric symptoms. A diagnosis of PANS or PANDAS may be supported by the Cunningham Panel, a commercially available set of immunologic assays currently in clinical use. However, the relationship between Cunningham Panel results and patient symptoms remains unclear...

PURPOSE OF REVIEW: Describe developments in the etiological understanding of Tourette syndrome. RECENT FINDINGS: Tourette syndrome is a complex heterogenous clinical syndrome, which is not a unitary entity. Pathophysiological models describe gamma-aminobutyric acid-ergic-associated disinhibition of cortico-basal ganglia motor, sensory and limbic loops. MRI studies support basal ganglia volume loss, with additional white matter and cerebellar changes. Tourette syndrome cause likely involves multiple vulnerability genes and environmental factors...

Tourette Disorder (TD) is a childhood-onset neuropsychiatric and neurodevelopmental disorder characterized by the presence of both motor and vocal tics. The genetic architecture of TD is believed to be complex and heterogeneous. Nevertheless, DNA sequence variants co-segregating with TD phenotypes within multiplex families have been identified. This report examines whole exomes of affected and unaffected individuals in a multiplex TD family to discover genes involved in the TD etiology. We performed whole exome sequencing on six out of nine members in a three-generation TD multiplex family...

The therapeutic applications of botulinum toxin (BoNT) have grown manifold since its initial approval in 1989 by the US Food and Drug Administration (FDA) for the treatment of strabismus, blepharospasm, and other facial spasms. Although it is the most potent biologic toxin known to man, long-term studies have established its safety in the treatment of a variety of neurologic and non-neurologic disorders. This review focuses on some novel and uncommon uses of BoNT in the treatment of movement disorders, such as oromandibular dystonia, including bruxism, anterocollis, camptocormia, tremor, tics, tardive and levodopa-induced dyskinesia, and restless legs syndrome...

Gilles de la Tourette syndrome is a neurodevelopmental disorder characterized by tics. Abnormal neuronal circuits in a wide-spread structural and functional network involved in planning, execution and control of motor functions are thought to represent the underlying pathology. We therefore studied changes of structural brain networks in 13 adult GTS patients reconstructed by diffusion tensor imaging and probabilistic tractography. Structural connectivity and network topology were characterized by graph theoretical measures and compared to 13 age-matched controls...

Very early-onset schizophrenia (defined as an onset of psychosis before 13 years of age) is a rare and severe form of the disorder which is clinically and neurobiologically continuous with the adult-onset disorder. It is rarely reported <12 years of age in Indian literature. Here, we present a 15-year-old boy who developed psychosis at 9 years of age and during illness developed tic disorder.

BACKGROUND: Restrictive eating problems are rare in children but overrepresented in those with neurodevelopmental problems. Comorbidities decrease wellbeing in affected individuals but research in the area is relatively scarce. This study describes phenotypes, regarding psychiatric and gastrointestinal comorbidities, in children with restrictive eating problems. METHODS: A parental telephone interview was conducted in 9- or 12-year old twins (n = 19,130) in the Child and Adolescent Twin Study in Sweden...

Tourette Syndrome (TS) is a neurodevelopmental condition characterized by chronic multiple tics, which are experienced as compulsive and 'unwilled'. Patients with TS can differ markedly in the frequency, severity, and bodily distribution of tics. Moreover, there are high comorbidity rates with attention deficit hyperactivity disorder (ADHD), obsessive compulsive disorder (OCD), anxiety disorders, and depression. This complex clinical profile may account for apparent variability of findings across neuroimaging studies that connect neural function to cognitive and motor behavior in TS...

PURPOSE/BACKGROUND: Antipsychotics are efficacious for tics and are increasingly prescribed to children with behavioral disorders. Antipsychotics have important adverse effects, and systematic monitoring of drug safety is infrequently performed. The objectives of this study were to determine the feasibility of antipsychotic safety monitoring in children with Tourette Syndrome using a defined protocol and to evaluate the risk of adverse effects with chronic use. METHODS/PROCEDURES: A prospective longitudinal study of children prescribed antipsychotics was performed...

BACKGROUND: Body-focused repetitive behaviors (BFRBs), such as hair pulling, skin picking, and nail biting, are repetitive, destructive, and nonfunctional habits that cause significant distress. Separate BFRBs form a cohesive group and could be assessed as part of the Tourette/tic spectrum or obsessive-compulsive spectrum of disorders. The treatment of choice is either antidepressant or behavioral treatment, both of which have shown effectiveness. The cognitive psychophysiological (CoPs) model focuses on the tension and emotional build up that triggers habits by addressing cognitive-behavioral, emotional and psychophysiological processes preceding onset rather than the habit itself...

Tourette syndrome (TS) is a common neuropsychiatric disorder, more common in males than females, with onset before age 18. TS is characterized by multiple motor tics and one or more vocal/phonic tics, persisting for more than a year. Tics are unvoluntary, abrupt, rapid, repetitive, but non-rhythmic movements or sounds (vocalizations). They are preceded by an inner urge. Tics can be temporarily suppressed, but this leads to a powerful re-emergence. The performance of tics results in immediate but transient relief...

The clinical surveillance and active management of Tourette syndrome (TS) and other primary chronic tic disorders cannot be limited to tics, as these patients manifest a spectrum of sensory-, behavioral-, cognitive-, and sleep-related problems that have a major impact on their functioning and quality of life, influencing enormously clinical decision making on a routine basis. The sensory phenomena of primary tic disorders consist of premonitory urges and heightened sensitivity to external somatosensory and interoceptive stimuli...

Copy-number variants (CNVs) are an important cause of human neurodevelopmental disorders. We present the first case of a 424 kb de novo 20q13.11q13.12 microdeletion in a patient with attention deficit disorder, tics and autistic behaviors, such as emotional and behavioral problems, and movement stereotypes. This region includes three genes expressed in the brain: SFRS6, PTPRT and L3MBTL. Our results suggest that loss of the chromosomal region 20q13.11q13.12 is causative for the clinical findings observed in the patient...

BACKGROUND: Huntington's disease (HD) is an autosomal dominant disorder, typically characterized by chorea due to a trinucleotide repeat expansion in the HTT gene, although the clinical manifestations of patients with juvenile HD (JHD) are atypical. CASE PRESENTATION: A 17-year-old boy with initial presentation of tics attended our clinic and his DNA analysis demonstrated mutation in the HTT gene (49 CAG repeats). After treatment, his symptoms improved. Furthermore, we performed literature review through searching the databases and summarized clinical features in 33 JHD patients...

BACKGROUND: Little is known about the academic performance of students with tic disorders (TD). Our aim was to investigate the association of TD and poor academic performance over time. METHODS: Longitudinal, observational study of mainstream schoolchildren comparing grade retention (GR) and learning disorders (LD) in students with vs. without TD between 2010 and 2014. Students with vs. without TD based on DSM-IV-TR criteria, or with vs. without GR and LD were compared in terms of comorbidities, school, and environmental characteristics...

PURPOSE: Major depressive disorder (MDD) is highly prevalent in patients with a chronic physical condition, and this comorbidity has a negative influence on quality of life, health care costs, self-care, morbidity, and mortality. Research has shown that collaborative care (CC) may be a cost-effective treatment. However, its cost-effectiveness in this patient group has not yet been established. Therefore, the aim of this study was to evaluate the cost-utility of CC for the treatment of comorbid MDD in chronically ill patients in the outpatient general hospital setting...

OBJECTIVES: Impaired response inhibition is related to neurodevelopmental disorders, such as Tourette's disorder (TD) and obsessive-compulsive disorder (OCD). Unlike OCD, in which neural correlates of response inhibition have been extensively studied, TD literature is limited. By using a Stop-Signal task, we investigated the neural mechanisms underlying response inhibition deficits in TD compared to OCD and healthy controls (HCs). METHODS: Twenty-three TD patients, 20 OCD patients and 22 HCs were scanned (3T MRI)...

For many years, Tourette syndrome (TS) was considered to be a rare disorder, but tics and TS are now recognized as fairly common childhood-onset conditions. Children and adolescents with TS are frequently treated with antipsychotics, either as monotherapy or in combination with psychostimulants, melatonin and selective serotonin reuptake inhibitors (SSRIs). Antipsychotics are most often used in schizophrenia and related psychotic disorders, and in these conditions hyperprolactinemia is one of the most common adverse effects associated with antipsychotics, occurring in 40-50% of patients...
