Attention-deficit hyperactivity disorder

Attention-deficit hyperactivity disorder (ADHD) is a medical condition that makes it hard for some people to focus on one thing for a long time, and/or to control their behavior.

ADHD can affect children and adults. It is more common in boys than girls. Some people with ADHD have difficulty paying attention to things that are not interesting to them, like a teacher in the classroom talking about a subject they do not like. Others may find it hard to sit still and focus on one thing without moving around or getting up.

Think of your brain like a computer. When you have ADHD, your brain has trouble managing and organizing information. Just like a computer can have too many tabs open at once, your brain can also have too much going on at the same time, making it hard to pay attention to one thing.

People with ADHD may also have trouble controlling their emotions and impulses. This means that they may act impulsively, without thinking about the consequences, and they may have trouble waiting their turn or following the rules.

ADHD is not caused by something a person did or didn't do. It is a medical condition that can be treated with medication, therapy, and changes in lifestyle. It is important to talk to a doctor if you or someone you know is having trouble focusing or behaving appropriately, to get the help and support needed to manage ADHD symptoms.
