Article Abstract

Attention-deficit/hyperactivity disorder (ADHD) is a highly prevalent, inheritable, and heterogeneous neurodevelopmental disorder. Children with a family history of ADHD are at elevated risk of having ADHD and persisting its symptoms into adulthood. The objective of this study was to investigate the influence of having or not having positive family risk factor in the neuroanatomy of the brain in children with ADHD. Cortical thickness-, surface area-, and volume-based measures were extracted and compared in a total of 606 participants, including 132, 165, and 309 in groups of familial ADHD (ADHD-F), non-familial ADHD (ADHD-NF), and typically developed children, respectively. Compared to controls, ADHD probands showed significantly reduced gray matter surface area in the left cuneus. Among the ADHD subgroups, ADHD-F showed significantly increased gray matter volume in the right thalamus and significantly thinner cortical thickness in the right pars orbitalis. Among ADHD-F, an increased volume of the right thalamus was significantly correlated with a reduced DSM-oriented t-score for ADHD problems. The findings of this study may suggest that a positive family history of ADHD is associated with the structural abnormalities in the thalamus and inferior frontal gyrus; these anatomical abnormalities may significantly contribute to the emergence of ADHD symptoms.

Chronic early-life obesity linked to childhood impulsivity predicts long-term psychosis trajectory through dose-dependent cerebellar dysmaturation in 22q11.2 Deletion Syndrome.

Background: Recent epidemiological evidence links early-life obesity and metabolic dysregulation to adult psychosis vulnerability, though a causal relationship remains unclear. Establishing causality in highly heritable psychotic disorders requires: 1) demonstrating that early-life metabolic factors mediate between genetic vulnerability and psychosis trajectory, 2) dissecting mechanisms leading to early-life obesity in genetically vulnerable individuals, and 3) clarifying downstream neurodevelopmental pathways linking early-life obesity to psychosis symptoms.

Methods: Here we investigated bidirectional pathways linking behavioral, BMI, and neurodevelopment trajectories in a unique longitudinal cohort of 184 individuals at high genetic risk for psychosis, due to 22q11.

Background: While associations between psychiatric disorders and hypothyroidism have been observed, the underlying causal relationships remain unclear. Exploring the causal relationships among them can provide new insights into the underlying mechanisms.

Methods: Two-sample Mendelian randomization (MR) was conducted to assess the causal effects of seven psychiatric disorders on hypothyroidism.

Attention-deficit/hyperactivity disorder in adults with epilepsy: Preliminary prevalence and associated factors in a Czech sample.

Objective: This study investigated the prevalence of Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms in Czech adult people with epilepsy (PWE) and examined factors potentially contributing to the co-occurrence of these two conditions. Although previous research has consistently reported elevated rates of ADHD in epilepsy populations, data from adult samples in Czech Republic remain limited.

Methods: Fifty-six adults with epilepsy completed validated self-report questionnaires assessing ADHD symptoms (ASRS), anxiety (GAD-2), and depression (NDDIE-2).

Exploring the sensory profile and pharmacogenetic biomarkers in child and youth ADHD patients undergoing methylphenidate (MPH) treatment: a systematic review conducted in European studies.

Methylphenidate (MPH) is the first-line treatment for Attention-Deficit/Hyperactivity Disorder (ADHD), a condition that disrupts daily functioning. Research indicates that individuals with ADHD often experience sensory processing impairments, regardless of co-occurring conditions. Given the growing interest in pharmacogenetics to personalise treatments and minimise side effects, this study aims to characterise the sensory profiles of in child and youth ADHD patients treated with MPH and investigate potential pharmacogenetic biomarkers that could be associated with treatment outcomes or sensory-related side effects.

Background: Sleep disturbances are highly prevalent in children with neurodevelopmental disorders (NDD), yet few studies have combined objective and subjective measures. The objectives of this study were to evaluate sleep patterns and sleep hygiene in children with ADHD and ASD compared age-matched typically developing children, using both parent-reported questionnaires and actigraphy, to assess the concordance between these measures, and to determine the clinical applicability of actigraphy in this population.

Methods: Sixty children with NDD (30 ASD, 30 ADHD) and 40 typically developing controls, matched for age, underwent seven nights of actigraphic recording.
