ADHD is a neurodevelopmental disorder that affects both children and adults, with symptoms often persisting into adolescence and beyond. It is characterized by persistent patterns of inattention, hyperactivity, and impulsivity that can significantly interfere with various aspects of life. ADHD can impact academic performance, work, relationships, and overall daily functioning. It often coexists with other conditions, such as learning disabilities or mood disorders. Management strategies may include behavioral interventions, psychoeducation, medication, and support from mental health professionals.
