Attention-Deficit/Hyperactivity Disorder (ADHD) in Children
What is ADHD in children?
disorder (ADHD) is a behavior disorder. It’s also called attention deficit disorder.
It’s often first diagnosed in childhood. There are 3 types:
ADHD, combined. 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. This is
the least common type of ADHD. A child is impulsive and hyperactive. But he or she
doesn’t have trouble paying attention.
ADHD, inattentive and distractible. 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?
Each child with ADHD may have different symptoms. He or she may have trouble paying attention. A child may also be impulsive and hyperactive. These symptoms most often happen together. But one may happen without the others.

A key part in diagnosis is that the symptoms must greatly affect how the child functions at home and in school. Make sure your child sees his or her healthcare provider for a diagnosis.
How is ADHD diagnosed in a child?
A pediatrician, child psychiatrist, or a mental health expert may diagnose ADHD. To do so, he or she will talk with parents and teachers and watch the child’s behavior. Diagnosis also depends on results from physical, nervous system, and mental health testing. Certain tests may be used to rule out other health problems. Others may check thinking skills and certain skill sets.
