What is ADHD in children?
Attention-deficit/hyperactivity disorder (ADHD) is a behavior disorder. It is also called attention deficit disorder. It is often first diagnosed in childhood. There are 3 major types:
· ADHD, combined type. This is the most common type. A child is impulsive and hyperactive. He or she also has trouble paying attention and is easily distracted.
· ADHD, impulsive/hyperactive type. This is the least common type of ADHD. A child is impulsive and hyperactive. But he or she does not have trouble paying attention.
· ADHD, inattentive and distractible type. A child with this type is mostly inattentive and easily distracted.
What causes ADHD in a child?
The exact cause of ADHD is unknown. But research suggests that it is genetic. It is a brain-based problem. Children with ADHD have low levels of a brain chemical (dopamine). Studies show that brain metabolism in children with ADHD is lower in the parts of the brain that control attention, social judgment, and movement.
Which children are at risk for ADHD?
ADHD tends to run in families. Many parents of children with ADHD had symptoms of ADHD when they were younger. The condition is often found in brothers and sisters within the same family. Boys are more likely to have ADHD of the hyperactive or combined type than girls.
Other things that may raise the risk include:
· Cigarette smoking and alcohol use during pregnancy
· Exposure to lead as a young child
· Brain injuries
· Low birth weight
What are the symptoms of ADHD in a child?
