What is ADHD?
ADHD stands for Attention Deficit Hyperactivity Disorder. It’s a brain disorder that affects how you pay attention, sit still, and control your behavior. It happens in children and teens and can continue into adulthood.
ADHD is the most commonly diagnosed mental disorder in children. Boys are more likely to have it than girls. It’s usually spotted during the early school years, when a child begins to have problems paying attention.
