Attention-deficit/hyperactivity disorder (ADHD) is a mental disorder that includes problems like difficulty paying attention and impulsive behaviour. ADHD can lead to unstable relationships, poor work or school performance, low self-esteem and other problems. Treatment for ADHD includes medications and psychotherapy. ADHD can be difficult to diagnose in adults because its symptoms are similar to other conditions, such as anxiety or mood disorders.

Symptoms start in early childhood and continue into adulthood. In adults, hyperactivity may decrease, but impulsiveness, restlessness and difficulty paying attention may continue. Beside from these, other symptoms are disorganization, poor time management skills, problems focusing or multitasking, excessive activity, frequent mood swings and hot temper
