Adult attention-deficit disorder

Adult attention deficit disorder (AADD) is the common terminology for the psychiatric condition currently known as attention-deficit hyperactivity disorder (ADHD), also known as attention deficit disorder (ADD), when it occurs in adulthood. Although the exact prevalence in adults is unknown, epidemiologic studies thus far reveal that the condition, marked by inattentiveness, difficulty getting work done, procrastination, or organization problems, probably exists in about 2-4% of adults. The condition persists to adulthood in about half of children diagnosed with the disorder.

Terminology

There is not yet a naming consensus. Below are listed several terms that have been used, past and present. One challenge in taxonomy is that some patterns of behavior are labeled by experts symptoms or sub-types of ADHD, while other experts label those same patterns as their own disorders, independent of ADHD. For the purposes of this article, the "Terminology" section will be used only to name ADHD and its near equivalents, while the names for its manifestations and subtypes will be listed in 'Symptoms', below.

• Attention-deficit hyperactivity disorder (ADHD): In 1987, ADD was in effect renamed to ADHD in the DSM-III-R. In it, ADHD was broken down into three subtypes (see 'symptoms' for more details):
• predominantly inattentive ADHD
• predominantly hyperactive-impulsive ADHD
• combined type ADHD
• Attention deficit disorder (ADD): This term was first introduced in DSM-III, the 1980 edition. Is considered by some to be obsolete, and by others to be a synonym for the predominantly inattentive type of ADHD.

Possibly due to the lesser evidence of hyperactivity symptoms in adults, the stigma attached to hyperactivity, or some combination of the two, many adults prefer the terms ADD or AADD to differentiate adult-related issues.
