Modern Classifications of ADHD
Not classified in Europe until ICD-9
First identified as ADD (with or without Hyperactivity) in DSM-III
- this contradicted ICD-9’s emphasis on hyperactivity
- DSM-III emphasized inattention and impulsivity
DSM-III-R further changed criteria (i.e. symptoms, single cut off scores) for this disorder and changed its name to ADHD
In DSM-IV the essential features of ADHD are patterns of inattention and/or hyperactivity-impulsivity
