Genetic Factors
Inherited genetic variations that increase the likelihood of developing ADHD. ADHD has a strong genetic component, with heritability estimates around 70-80%.
Overview
ADHD has a strong genetic component, with heritability estimates around 70-80%, meaning genetics play a major role in ADHD development.
Detailed Description
Research shows that ADHD runs in families and has a strong genetic basis. If a parent has ADHD, their child has about a 25-35% chance of having ADHD. If a sibling has ADHD, the risk is about 30-40%. Multiple genes are involved, and it's likely that different combinations of genetic factors contribute to ADHD in different individuals. However, genetics alone don't determine ADHD - environmental factors also play a role.
How This Relates to ADHD
Understanding the genetic basis of ADHD helps reduce stigma by emphasizing that ADHD is a biological condition, not a result of parenting or personal choices. It also explains why ADHD often runs in families.
Treatment and Management
While we can't change genetics, understanding genetic factors helps inform treatment approaches and family planning decisions.
