ADHD is a neurodevelopmental disorder that affects attention, impulsivity, and hyperactivity. Symptoms include difficulty focusing, forgetfulness, poor time management, restlessness, and trouble following instructions. There are three types:

• Predominantly Inattentive Presentation: Struggles with focus, organization, and completing tasks.
• Predominantly Hyperactive-Impulsive Presentation: Characterized by fidgeting, interrupting others, and acting without thinking.
• Combined Presentation: Features both inattentive and hyperactive-impulsive traits.

ADHD affects academic, professional, and social life. Treatment options include behavioral therapy, coaching, medication, and lifestyle modifications to improve focus and self-regulation.
