Attention Deficit Disorder (ADD)
A disorder characterized by a difficulty in retaining focus, especially on tasks, for long periods of time.
Note: One of the most common reasons children are brought into therapy, ADD is often treated with the somewhat controversial drug Ritalin®, which is thought to work by stimulating the attention-focusing structures of the brain.
