Attention deficit hyperactivity disorder (ADHD) is a common childhood condition that often persists into adulthood. Genetic factors play a significant role in ADHD, interacting with environmental influences.

Area of Science:

  • Neuroscience
  • Genetics
  • Psychiatry

Context:

  • Attention deficit hyperactivity disorder (ADHD) is a prevalent neuropsychiatric disorder in children, frequently persisting into adulthood.
  • Genetic factors are increasingly recognized for their role in ADHD pathophysiology.
  • Adult ADHD provides a valuable model for understanding the disorder's genetic underpinnings.

Purpose:

  • To provide an updated overview of the genetic foundations of ADHD.
  • To highlight recent genetic findings, particularly concerning adult ADHD.

Summary:

  • Familial, twin, and adoption studies indicate significant heritability of ADHD.
  • Molecular genetics research identifies associations between ADHD and polymorphisms in neurotransmitter systems (dopaminergic, serotoninergic, noradrenergic) and neurotrophins like BDNF.

  • While ADHD causation is complex and multifactorial, genetics are a key component, modulated by environmental factors.

    • Impact:

    • Enhances understanding of ADHD's complex genetic architecture.
    • Informs future research directions in ADHD genetics.
    • May contribute to improved diagnostic and therapeutic strategies for ADHD in both children and adults.
