Attention Deficit Hyperactivity Disorder (ADHD) is a chronic ann incapacita
ting mental disorder characterized by overactivity, inattention and impulsi
veness. The syndrome is usually diagnosed in childhood and it continues int
o adulthood. However, because the symptoms of ADHD frequently overlap with
other categories of psychopathology, in adults it is often underdiagnosed o
r neglected, and left untreated. This paper emphasizes the importance of re
cognizing this syndrome in adulthood. To this end, we provide a review of t
he literature and four illustrative cases of our own. Appropriate treatment
is also discussed.
