Aspects of autism spectrum disorder and correlation with neuroimaging findings in tuberous sclerosis complex.

Background: Tuberous sclerosis complex (TSC) patients may have different specific neuropsychological deficits related to the location of the tubers. Autism spectrum disorders (ASD) are common in TSC patients but the relationship between these diagnoses has not been formally explored. In this study we sought to examine brain Magnetic Resonance Imaging (MRI) findings in TSC patients with ASD.

Serum Zonulin Levels Are Higher Among Children with Autism Spectrum Disorders and Correlated with Social Impairment.

Objective: Zonulin is a protein that affects the integrity of intercellular connections in the intestines. It has been emphasized that autoimmune diseases as well as neurodevelopmental disorders, for example autism spectrum disorder (ASD), may occur through alterations in intestinal permeability and blood-brain barrier. We aimed to investigate the gastrointestinal permeability of individuals with ASD by determining serum zonulin levels and their relationship to symptom severity.

A Retrospective Evaluation on Demographic, Phenomenological, and Comorbidity Features of Pediatric Obsessive-Compulsive Disorder.

The impacts of sex, age of onset, phenotype, and comorbidity on clinical features were explored in a large clinical sample with pediatric obsessive-compulsive disorder (p-OCD) (n = 457), along with concomitant specific features in the framework of different symptom dimensions/phenotypes, by a retrospective cross-sectional evaluation design. The most prevalent phenotype was obsession/checking (almost half), and the clinical features belonging to different phenotypes varied among sexes, age of onset, severity, and comorbidities. The contamination and aggressive obsessions, along with the compulsions such as cleaning and repeating routine activities, were the most prevalent symptoms, which were prevalently accompanied by generalized anxiety disorder, attention deficit hyperactivity disorder, and depression.

Impact of Parental Impulsivity on Attention Deficit Hyperactivity Disorder and Oppositional Defiant Disorder: Do Mothers' Attitudes Predict Symptom Severity in Children?

Attention deficit hyperactivity disorder (ADHD) is a chronic neurodevelopmental disorder that occurs early in school-aged children, and it is highly comorbid with oppositional defiant disorder (ODD). Parents of children with ADHD frequently show mental problems related to impulsivity. The aim of this study was to examine the relationship between impulsivity of the mothers and the symptom patterns and severity of children.
