Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder commonly diagnosed in children, though it can persist into adulthood. It is characterized by symptoms such as inattention, hyperactivity, and impulsivity, which can affect daily functioning and relationships. Individuals with ADHD may struggle to focus on tasks, follow instructions, or sit still. These challenges can lead to difficulties in school, work, and social situations. Treatment options often include behavioral therapy, medication, and support strategies to help manage symptoms effectively.
