Attention deficit disorder (ADD): An inability to control behavior due to difficulty in processing neural stimuli.

In November, 1998 the National Institutes of Health (NIH) issued a consensus report developed by a panel of experts. The panel concluded that:

• Ritalin and other therapies may correct classroom behavior problems but there is no evidence that this improves a child's academic performance.
• Although there is no independent, validated test for ADD, some well-tested diagnostic interview methods have proved useful.
• Short-term trials of Ritalin and other drugs show beneficial effects on some behaviors and are superior to behavior modification training. Combining the two resulted in improved social skills.
• Numerous other treatments have been tried, including vitamins, herbs, biofeedback and eliminating some foods such as sugar. None have proved effective.
• Doctors and schools usually do a poor job of communicating and coordinating when treating children with ADD and follow-up often is poor. Teachers and parents can play a key role in successfully A treating ADD.
