Understanding Adult ADHD
ADHD (Attention-Deficit/Hyperactivity Disorder) doesn’t disappear when you turn 18. Many people with childhood ADHD continue experiencing symptoms into adulthood, though symptoms may present differently as adults learn coping strategies.
Why Adult ADHD Goes Undiagnosed
Different Presentation in Adults
- Hyperactivity may become internal restlessness
- Less obvious than in children
- Often attributed to personality traits
- Masked by developed coping mechanisms
- May not seem like a “disorder” if functional
Historical Reasons
- ADHD was less recognized in children of past generations
- “Quieter” ADHD types were missed
- Girls especially underdiagnosed
- Symptoms attributed to other conditions (laziness, lack of motivation)
Diagnostic Bias
- Adults compensate for symptoms
- Symptoms may vary by context
- High-functioning ADHD missed
- Comorbid conditions may overshadow ADHD
- Many adults self-diagnose late
