What is the inheritance pattern of ADHD?

ADHD is passed down primarily through genetics, meaning it runs in families because children inherit gene variations from parents that affect brain development, especially dopamine regulation, making it highly heritable, though not a simple Mendelian trait. While genes are crucial, environmental factors like premature birth, prenatal substance exposure (smoking/alcohol), low birth weight, and early trauma also contribute, interacting with genetics to influence risk.

What is the 30% rule in ADHD?

The ADHD "30% Rule" is a guideline suggesting that executive functions (like self-regulation, planning, and emotional control) in people with ADHD develop about 30% slower than in neurotypical individuals, meaning a 10-year-old might function more like a 7-year-old in these areas, requiring adjusted expectations for maturity, task management, and behavior. It's a tool for caregivers and adults with ADHD to set realistic goals, not a strict scientific law, helping to reduce frustration by matching demands to the person's actual developmental level (executive age) rather than just their chronological age.

What is the 2 minute rule for ADHD?

The ADHD "2-Minute Rule" suggests doing any task taking under two minutes immediately to build momentum, but it often backfires by derailing focus due to weak working memory, time blindness, and transition difficulties in people with ADHD. A better approach is to write down these quick tasks on a separate "catch-all" list instead of interrupting your main work, then schedule specific times to review and tackle them, or use a slightly longer timeframe like a 5-minute rule to prevent getting lost down "rabbit holes".

What is the 24 hour rule for ADHD?

The 24-hour rule for ADHD is a self-regulation strategy to combat impulsivity by creating a mandatory waiting period (often a full day) before reacting to emotionally charged situations or making significant decisions, allowing time for reflection and reducing regretful snap judgments, especially for things like impulse purchases or arguments. It's a pause button that gives the brain space to process, move from impulse to intention, and evaluate choices more logically, helping manage ADHD's impact on emotional regulation and decision-making.
