Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental condition that affects both children and adults, characterized by persistent patterns of inattention, hyperactivity, and impulsivity that interfere with functioning or development.

Individuals with ADHD may struggle with focusing, following through on tasks, organizing activities, sitting still, or controlling impulses. Symptoms can vary in type and severity and are commonly grouped into three presentations: predominantly inattentive, predominantly hyperactive-impulsive, or combined.

While the exact cause of ADHD is not fully understood, research suggests a combination of genetic, neurological, and environmental factors. With proper diagnosis and a comprehensive treatment plan—which may include behavioral therapy, medication, and supportive strategies—individuals with ADHD can manage symptoms effectively and thrive in daily life.
