Is ADHD a type of mental illness?

No, ADHD (Attention Deficit Hyperactivity Disorder) is not considered a mental illness. It is a neurodevelopmental condition that affects how a person's brain functions, specifically in the areas of attention, impulse control, and hyperactivity. Mental illnesses usually refer to conditions that significantly affect a person's thoughts, feelings, and behaviors, often causing distress and impairing daily functioning. ADHD, on the other hand, primarily affects the individual's ability to focus, pay attention, and control their behavior. It is a distinct neurodevelopmental condition with its own unique characteristics and treatment approaches.
