Article Abstract

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). Epilepsy-related clinical factors, such as seizure frequency, anti-seizure medication (ASM), type of epilepsy and epilepsy duration, were also analyzed in relation to ADHD symptoms.

Results: A high prevalence of ADHD symptoms n = 25 (44.6 %) was found in the sample. No significant associations were observed between ADHD symptoms and epilepsy-related variables or depressive symptoms, but a regression model of clinical and sociodemographic variables can explain 34.2 % of the variance in ASRS scores (Adj. R² = 0.342), with only anxiety emerging as a significant predictor (β = 0.517, SE = 0.50, t = 3.23, p = .003).

Conclusion: These preliminary findings suggest a possible link between epilepsy and ADHD, which may be further explored in future research through shared emotional or neurobiological mechanisms. The results underscore the need for integrated screening approaches and further research into the co-occurrence of epilepsy and ADHD in adult populations.

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.

Adolescence is frequently called the second brain maturation period. In Tourette disorder (TD), the clinical trajectory of tics and associated psychiatric co-morbidities vary significantly across individuals during the transition from adolescents to adulthood. In this study, we aimed to identify patterns of resting-state functional connectivity that differentiate adolescents with TD from their neurotypical peers, and to monitor symptom-specific functional changes over time.

Study Objectives: Chronotype has been linked to a wide variety of psychiatric conditions. In particular, evening chronotype could be a transdiagnostic risk factor for different mental health difficulties. In this study we examine how chronotype relates to psychopathology and whether it can be conceptualised as part of the global construct of psychopathology (p-factor) by studying the genetic and environmental overlap between these variables.

Developmental Dyslexia (DD) and Attention-deficit/hyperactivity disorder (ADHD) are neurodevelopmental disorders that often coexist and share complex genetic underpinnings. Our case study integrates psychological assessments and whole exome sequencing to explore the genetic basis of DD and ADHD co-occurrence in a single proband (a nine-year-old female born to healthy) from a consanguineous Pakistani family. We present a proband with symptoms of impulsivity, inattention, and severe hyperactive behavior, along with speech impairment and moderate learning disabilities.
