Attention-deficit hyperactivity disorder, or ADHD, is a developmental disorder that primarily affects children, but can also affect adults. Symptoms may include inattentiveness, impulsive behavior and concentration difficulties. Treatment aims to control symptoms and may include social skills training and drug therapy. The University of Maryland Medical Center notes that stimulants, such as methylphenidate and amphetamine, are the most commonly prescribed drug treatments. Some research suggests that ginkgo biloba may also help to alleviate ADHD symptoms, but get medical advice before using it.
