What is Attention Deficit Hyperactivity Disorder?

Essential facts and insights about Attention Deficit Hyperactivity Disorder

Key Clinical Considerations:

Inattention: Difficulty sustaining attention, careless mistakes, difficulty organizing tasks.
Hyperactivity: Fidgeting, inability to stay seated, excessive talking.
Impulsivity: Interrupting others, difficulty waiting turn, blurting out answers.
Key diagnostic tests/findings: Behavioral assessments, ADHD-specific rating scales (e.g., Conners Scale).
Physical exam findings: No definitive physical findings; may assess for comorbid conditions.
