Hyperactivity disorder is most commonly referred to as attention deficit hyperactivity disorder, or ADHD. According to the National Institute of Mental Health, ADHD is among the most common disorders affecting children and can persist throughout a patient's life.

Statistics

According to Children's Hospital Boston, an estimated 2 million children in the United States have ADHD, with boys being two to three times more likely to develop the disorder than girls.

Symptoms

There are three categories of ADHD symptoms: inattention, hyperactivity and impulsivity. Symptoms of inattention include difficulty focusing, being easily distracted, forgetfulness, rapidly becoming bored and difficulty following directions. Hyperactivity symptoms include fidgeting, constant motion, nonstop talking and difficulty performing quiet activities. Impulsivity symptoms include interrupting conversations, blurting comments, acting out, difficulty waiting and impatience.

Types of Hyperactivity Disorder

There are three types of ADHD, including predominately inattentive, predominately hyperactive-impulsive, and combined hyperactive-impulsive and inattentive. The groups are classified in accordance with the patient's dominant symptoms.

Causes

There is no single factor which can be pinpointed as a cause of hyperactivity disorder. However, according to the National Institute of Mental Health, possible risk factors may include genetics, brain injuries, and exposure to cigarette smoke or alcohol while in the womb.

Treatment

Treatments may include stimulant medications such as amphetamine, methylphenidate or atomoxetine; psychotherapy; or a combination of the two.
