ADHD, or Attention-Deficit/Hyperactivity Disorder, is a neurodevelopmental condition characterized by persistent patterns of inattention, hyperactivity, and impulsivity that significantly impact daily functioning and academic performance. It affects individuals across different age groups and can interfere with learning, social interactions, and self-regulation. Treatment options for ADHD often include a combination of behavioral interventions, medication, and support strategies to manage symptoms and improve functioning.
