ADHD or ADD?
"ADHD" (attention-deficit/hyperactivity disorder) is the term now used for a condition which has had several names over the past hundred years. Science recognizes three subtypes of ADHD (inattentive, hyperactive-impulsive, and combined). A diagnosis of one type or another depends on the specific symptoms (i.e. the "diagnostic criteria") that person has.
While some individuals, including many professionals, still refer to the condition as "ADD" (attention deficit disorder), this term is no longer in widespread use. For those who may have been diagnosed with ADD, the corresponding diagnostic category, using current terminology, would mostly likely be "ADHD, Predominantly Inattentive Type."
