What is Adult ADHD?

Adult ADHD (Attention-Deficit/Hyperactivity Disorder) is a neurodevelopmental condition that affects focus, organization, impulse control, and emotional regulation. Although commonly diagnosed in childhood, ADHD often continues into adulthood—sometimes undiagnosed for years. Adults with ADHD may struggle with managing time, completing tasks, maintaining relationships, and staying organized in work or personal life. Recognizing and diagnosing ADHD in adults is crucial for effective treatment and improved quality of life.
