Decades of research show that genes play an vital role in the etiology of attention deficit hyperactivity disorder (ADHD) and its comorbidity with other disorders. Family, twin, and adoption studies show that ADHD runs in families. ADHD’s high heritability of 74% motivated the search for ADHD susceptibility genes.

Based on the results of family and twin studies, the estimated heritability of ADHD approximates 80%, suggests a significant genetic component in the etiological background of the disorder; however, the potential genetic effects on disease risk, …

Available evidence suggests that ADHD is genetic—passed down from parent to child. ADHD seems to run in at least some families. At least one-third of all fathers who had ADHD in their youth have children with the condition. What’s more, …

Jun 23, 2023 · Attention deficit hyperactivity disorder (ADHD) tends to be hereditary, and it appears to have strong genetic links. While researchers acknowledge that some genetic variants increase a...

ADHD is commonly accompanied by other psychiatric and behavioural disorders, notably conduct disorder as well as developmental conditions (e.g. dyslexia, autism), tic disorders, depression and anxiety (Taylor & Sonuga-Barke, 2008). In this review we …

Jan 26, 2023 · We identified 27 genome-wide significant loci, highlighting 76 potential risk genes enriched among genes expressed particularly in early brain development. Overall, ADHD genetic risk was...

Mar 14, 2025 · ADHD likely has a genetic or heritable component to it, meaning certain genes you inherit from your parents or certain genetic mutations you develop may contribute to its development.

Decades of research show that genes play an vital role in the etiology of attention deficit hyperactivity disorder (ADHD) and its comorbidity with other disorders. Family, twin, and adoption studies show that ADHD runs in families. ADHD's high heritability of 74% motivated the search for ADHD susceptibility genes.

Aug 16, 2018 · Recent discoveries reveal the strong genetic overlaps between ADHD and autism spectrum disorder (ASD) as well as intellectual disability. Thus, the removal of the previous diagnostic exclusion criteria for ADHD in the presence of ASD is a welcome change in DSM-5.

Aug 4, 2024 · Attention Deficit Hyperactivity Disorder (ADHD) has long been a subject of intense scientific scrutiny, with researchers delving deep into the intricate interplay between genetics and behavior.
