come into prominence in 70s
diagnosing and treatment has improved over past 20 years
clinical presentation
used to be thought of developmental problems in the womb
1980 - attention deficit began to be viewed as cornerstone of the disorder
1994 - DSM-IV combined symptoms of hyperactivity, impulsivity, and inattention
three main presentations:
ADHD - predominately inattentive
most common in girls and adults
ADHD - predominately hyperactive
ADHD - combined
most common mainly in boys
very different from child to child
easily recognizable in kids who are physically active and viewed by others as impulsive/disruptive
may become isolating as they get older
