Anxiety is highly prevalent in children with an autism spectrum disorder (ASD). However, there is inconsistency in studies investigating the prevalence and risk factors of anxiety in children with ASD. Therefore, the first aim of this study was to give an overview of the prevalence of anxiety symptoms in a clinical Dutch sample of children with ASD. The second aim was to investigate age, gender, ASD subtype, and IQ as potential risk factors for anxiety in this sample. In total, 172 children with ASD (age, 8-15 years) and their parents participated in this study...

BACKGROUND: Autism spectrum disorders are serious neurodevelopmental disorders that affect approximately 1% of the population. These disorders are substantially influenced by genetics. Several recent linkage analyses have examined copy number variations associated with autism risk. Microdeletion of the 2q13 region is considered a pathogenic copy number variation. This microdeletion is involved in developmental delays, congenital heart defects, dysmorphism, and various psychiatric disorders, including autism spectrum disorders...

In a prior report, we showed that extended-release guanfacine (GEXR) is safe and effective for children with autism spectrum disorder (ASD) accompanied by ADHD symptoms. Here, we examine the impact of GEXR on oppositional behavior, anxiety, repetitive behavior, and sleep disturbance. Sixty-two subjects with ASD (53 boys, 9 girls; ages 5-14 years) were randomly assigned to GEXR (n = 30) or placebo (n = 32) for 8 weeks. Outcomes include the Home Situation Questionnaire-Modified for ASD (HSQ-ASD), Anxiety scale of the Child and Adolescent Symptom Inventory (CASI), Children's Yale-Brown Obsessive-Compulsive Scale-Modified for ASD (CYBOCS-ASD), and Children's Sleep Habits Questionnaire (CSHQ)...

Rett syndrome is an X-linked neurodevelopmental disorder associated with psychomotor impairments, autonomic dysfunctions and autism. Patients with Rett syndrome have loss-of-function mutations in MECP2, the gene encoding methyl-CpG-binding protein 2 (MeCP2). Abnormal biogenic amine signaling and mitochondrial function have been found in patients with Rett syndrome; however, few studies have analyzed the association between these factors. This study investigated the functional relationships between mitochondria and the neuronal differentiation of the MeCP2-deficient stem cells from the exfoliated deciduous teeth of a child with Rett syndrome...

Genetic alterations, together with environmental risk factors during infancy and childhood, contribute significantly to the etiology of autism spectrum disorder (ASD), a heterogeneous neurodevelopmental condition characterized by impairments in social interaction and restricted, repetitive behaviors. Mounting evidence points to a critical contribution of immunological risk factors to the development of ASD. By affecting multiple neurodevelopmental processes, immune system dysfunction could act as a point of convergence between genetics and environmental factors in ASD...

INTRODUCTION: Organophosphates are widely used pesticides that have been shown to affect child neurodevelopment. Previous studies that explored their potential effects on Autism Spectrum Disorder (ASD) relied either on proxies of external exposure or on questionnaires completed by the parents to identify autism-like behaviors but did not provide a clinical diagnosis of ASD. AIMS: We studied the associations between prenatal biologic markers for exposure to organophosphate pesticides and the risk of having a child with ASD or other developmental concerns (ODC)...

The ratio of the index (2nd) finger to ring (4th) finger lengths (2D:4D) is a proxy for fetal testosterone and estradiol. Studies suggesting 2D:4D is inversely associated with autism spectrum disorder (ASD) in males were limited by lack of confounder and subgroup assessments. Studies of females are sparse. We examined associations between ASD and 2D:4D among children in the Study to Explore Early Development; we considered case subgroups and numerous potential demographic and maternal-perinatal health confounders...

BACKGROUND: Monogenic defects of synaptic vesicle (SV) homeostasis have been implicated in many neurologic diseases, including autism, epilepsy, and movement disorders. In addition, abnormal vesicle exocytosis has been associated with several endocrine dysfunctions. METHODS: We report an 11 year old girl with learning disabilities, tremors, ataxia, transient hyperglycemia, and muscle fatigability responsive to albuterol sulfate. Failure of neuromuscular transmission was confirmed by single fiber electromyography...

Importance: The prevalence of autism spectrum disorder (ASD) has been increasing rapidly, with current estimates of 1 in 68 children affected. Simultaneously, use of prenatal ultrasonography has increased substantially, with limited investigation into its safety and effects on brain development. Animal studies have demonstrated that prenatal ultrasonography can adversely affect neuronal migration. Objective: To quantify prenatal ultrasound exposure by the frequency, timing, duration, and strength of ultrasonographic scans in children with later ASD, developmental delay, and typical development...

Sleep disorders are frequently reported in autistic patients. Evidences suggest that increased oxidative stress and reduced antioxidants may play a major role in the pathogenesis of these disorders. Carnosine acts as an antioxidant, antitoxic and neuroprotective agent. The aim of this trial study was to examine the effects of carnosine supplementation on the sleep disorders and severity of autism core symptoms in autistic patients. In this double-blind, randomized clinical trial, 43 autistic patients (31 boys and 12 girls; aged 4 to 16 years) were divided into two groups of carnosine and control that received 500 mg of carnosine and 500 mg of placebo per day for two months, respectively...

Autism spectrum disorder (ASD) is defined by the triad of deficits in social interactions, deficits in communication, and repetitive behaviors. Common co-morbidities in syndromic forms of ASD include intellectual disability, seizures, and obesity. We asked whether very obese children with ASD had different behavioral, physical and genetic characteristics compared to children with ASD who were not obese. We found that very obese children with ASD had significantly poorer scores on standardized behavioral tests...

This study is a systematic replication of a functional analysis (FA) of the relation between mands and problem behavior. We extended treatment approaches for this problem behavior function, and describe the treatment of problem behavior related to mands for rearrangement demonstrated by a 12-year-old girl with autism spectrum disorder and Smith-Magenis syndrome. The mands consisted of requests for others to change their body positioning or proximity, or rearrange items back to their original position. An FA confirmed the relation between problem behavior and mand compliance, and functional communication training with extinction decreased problem behavior and increased functional communication responses...
