Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that affects how a person pays attention, stays focused, and controls impulses. It is one of the most common mental disorders in children and adolescents. A checklist for ADHD can help parents and caregivers to be aware of the symptoms of ADHD and seek early diagnosis and treatment. The checklist can also help to monitor the progress of treatment and identify any problems that may occur.
