Could it be ADHD?

Kids will be kids. But how do you know if their actions are concerning enough to be a medical condition?

Attention-deficit/hyperactivity disorder (ADHD) is the most common neurodevelopmental disorder. It replaces attention deficit disorder (ADD), an outdated term that is no longer used.

ADHD is associated with an ongoing pattern of inattention, hyperactivity, and/or impulsivity. The disorder can interfere with daily activities, social relationships, and school performance. ADHD begins in childhood and can continue as a teen or adult.

According to the National Institute of Mental Health, ADHD affects 3 to 5 percent of preschool and school-age children. Symptoms include:

• Inattention—Difficulty paying attention
• Hyperactivity—Too much energy or moving and talking too much
• Impulsivity—Acting without thinking or having difficulty with self-control

Some people with ADHD mainly have symptoms of inattention. Others mostly have symptoms of hyperactivity-impulsivity. Some people have both types of symptoms. The symptoms can be mild, moderate, or severe.

The cause of ADHD is unknown, but current research shows that genetics plays an important role, according to the Centers for Disease Control and Prevention. Research does not support claims that ADHD is caused by eating too much sugar, watching too much television, parenting, or social and environmental factors, such as poverty or family problems.

Diagnosing ADHD in young children is difficult since developmental problems, such as language delays, can be mistaken for ADHD, according to the Mayo Clinic.

There is no single test to diagnose ADHD. One step of the process involves having a medical exam, including hearing and vision tests, to rule out other problems. Preschool children or younger who are suspected of having ADHD more likely need to be evaluated by a specialist, such as a psychologist or psychiatrist, speech pathologist, or developmental pediatrician.

ADHD is a highly treatable condition. Medications and behavior therapy can help manage symptoms but will not cure the condition.
