Attention Deficit Disorder, or ADD is a psychological term currently applied to anyone who meets the DSM IV diagnostic criteria for impulsivity, and/or inattention. The diagnostic criteria are subjective and include behavior which might be caused by a wide variety of factors, ranging from brain defects to allergies to giftedness. ADD, as currently defined, is a highly subjective description, not a specific disease.
Thav AKA Andrew is a prime example of ADD.
