Answer:
ADHD is diagnosed <u>twice as</u> often in girls than in boys. In the decade after 1987, a(n) <u>significal increased</u> proportion of American children have been treated for this disorder.
Explanation:
The American Psychiatric Association (APA) released a revised version of the: Diagnostic and Statistical Manual of Mental Disorders, Third Edition (DSM-III) in 1987. In wich, they removed the hyperactivity distinction and changed the nomenclature to attention deficit hyperactivity disorder (ADHD).
They combined the three symptoms ( impulsivity, inattentiveness, and hyperactivity) into a single type.
According to National Trends in the Treatment of Attention Deficit Hyperactivity Disorder (Mark Olfson, M.D., M.P.H., Marc J. Gameroff, Ph.D.
, Steven C. Marcus, Ph.D. & Peter S. Jensen, M.D.) :
"The rate of outpatient treatment for ADHD increased from 0.9 per 100 children in 1987 to 3.4 per 100 children in 1997."
In 1990s, cases of diagnose ADHD began to increase, due a number of factors:
-
doctors were able to diagnose it more efficiently
- more parents were aware of ADHD, thanks to the increase of informationin this subject, and are reporting their children’s symptoms
- and least, more children were actually developing ADHD
When the APA released their fourth edition of the Diagnostic and Statistical Manual of Mental Disorders in 2000, they established the three subtypes of ADHD used by healthcare professionals today:
- predominantly inattentive type ADHD
- predominantly hyperactive-impulsive type ADHD
