No, it's the same disorder. The name was changed from Attention Deficit Disorder to Attention Deficit Hyperactivity Disorder. From WebMD:
Quote:
Attention deficit hyperactivity disorder (ADHD) is a condition in which a person has trouble paying attention and focusing on tasks. It may begin in early childhood and can continue into adulthood. Without treatment, ADHD can cause problems at home, school, work, and with relationships. ADHD was once called attention deficit disorder (ADD).
There have always been several subtypes of the disorder, which are used to specify whether or not hyperactivity is involved. The subtypes are: Predominantly Hyperactive Subtype, Combined Subtype, and Predominantly Inattentive Subtype.
Today, someone who meets the criteria for the disorder and is not hyperactive would be diagnosed with Attention Deficit Hyperactivity Disorder - Predominantly Inattentive Subtype.
The word "hyperactivity" is included in the name of the disorder because the majority of people who meet the criteria are hyperactive. The Predominantly Inattentive Subtype has the lowest rate of diagnosis.
Imagine if AS was renamed Intense Narrow Interest Obsessive Autistic Disorder (horrible, awkward name, I know). Not everyone with AS has an obsession - one can meet the criteria for AS without having this feature. But the majority of people with AS do have these intense narrow interests, so it could hypothetically be included in the name.
