Objective: The objective was to determine the differential validity of a cognitive disengagement syndrome-only (CDS-only) group from ADHD-inattentive presentation-only (IN-only), ADHD-hyperactive-impulsive presentation-only (HI-only), and ADHD-combined presentation (C-only) groups within childhood (ages 5-10) and adolescence (ages 11-16). Methods:…

Objective: There is growing evidence of involvement of inflammatory mechanisms in ADHD. Previous studies found significantly higher rates of ADHD among children with FMF. The present study examined the rate of exposure to FMF in children with a later (within a 5-year period) diagnosis of ADHD compared to non-ADHD children. Methods: A…

Objective: Around 70% of adolescents with ADHD experience sleep and/or homework problems. Both impairments have been previously associated with neuropsychological deficits but have not been simultaneously examined in adolescents with ADHD and clinical sleep problems. Therefore, this study investigated how sleep problems are associated with…

Although sometimes perceived as a well-known condition, there are numerous aspects of Attention Deficit Hyperactivity Disorder (ADHD) which we do not fully understand. Given the preponderance of previous ADHD research with males, the need for understanding females' experiences of living with the condition is pressing. This article presents…

Objective: We examined the association between the number, magnitude, and frequency of febrile episodes during the 0 to 4 years of life and subsequent diagnosis of ADHD. Methods: This population-based case-control study in an Israeli HMO, Leumit Health Services (LHS), uses a database for all LHS members aged 5 to 18 years between 1/1/2002 and…

Objectives: Previous studies have demonstrated poor oral hygiene in children with attention deficit hyperactivity disorder (ADHD). However, the association between ADHD and periodontitis is still unclear. Methods: In all, 16,211 adolescents with ADHD and 162,110 age- and sex-matched controls participated in the study between 2001 and 2011. To…

The present study explored whether poor executive functions (EF) underlying the difficulties of individuals with ADHD in reading comprehension (RC) are general or specific to the textual content they regulate. To address this question, adolescents with and without ADHD answered questions following the reading of texts and completed a series of…

Objective: Although ADHD is highly heritable, some environmental factors contribute to its development. Given the growing evidence that gut microbiota was involved in psychiatric disorders, we aimed to identify the characteristic composition of the gut microbiota in ADHD. Methods: We recruited 47 medication-naive children and adolescents with…

Objective: The study involved 17 children with Autism Spectrum Disorder (ASD), 21 with ADHD, 30 with both (ASD + ADHD), and 28 typically developing children (TD). Methods: The amplitude of low-frequency fluctuations (ALFF) was measured as a regional brain function index. Intrinsic functional connectivity (iFC) was also analyzed using the region of…

Background: White noise stimulation has demonstrated efficacy in enhancing working memory in children with ADHD. However, its impact on other executive functions commonly affected by ADHD, such as inhibitory control, remains largely unexplored. This research aims to explore the effects of two types of white noise stimulation on oculomotor…

Objective: To develop a short version of the Spanish 18-item ADHD-Rating Scale IV.es (sADHD-RS-IV.es) to be used as a potential screening tool in pediatric population. Methods: We recruited 652 subjects, ages 6 to 18 (mean ± SD = 11.14 ± 3.27): 518 patients with ADHD (per DSM-IV criteria); and 134 healthy controls. We performed a stepwise logistic…

Social skills group training is frequently used to support autistic children and adolescents in coping with everyday social demands and expectations. Meta-analytic studies suggest small to medium effect sizes. Effect moderators must be better understood to inform implementation and allow optimization of intervention protocols. Using data from two…

An accurate global assessment of gifted children is essential to provide them with educational and counseling programs tailored to their strengths and vulnerabilities. Without neglecting the fundamental role of social-emotional skills on individual well-being and academic success, it is essential to shedding light on the attentional profile of…

Sleep problems are prevalent in autism spectrum disorder (ASD) and have a range of causes, including circadian rhythm misalignment. However, little is known about sleep in autistic children with co-occurring attention deficit hyperactivity disorder (ADHD). A cross-sectional descriptive and analytic study was conducted in 87 autistic children and…

This study explored the manner in which poor planning skill impairs reading comprehension of students with ADHD. Ninety-six adolescents with and without ADHD completed a planning task (Tower of London) and answered open-ended questions following the reading of two expository texts under two reading goals - study and entertainment, while their…
