Quick answer: the current DSM-5 diagnosis is ADHD - Attention Deficit/Hyperactivity Disorder. This diagnosis is given whether the individual has hyperactive symptoms or not.
Detailed answer (The ADHD Storytelling Answer):
Once upon a time, around 1902 or so, there was a doctor who cared for children. We call these kinds of docs, pediatricians. Paediatrician if you want to spell it the fancy way.
His name was Fred. He noticed that there were some children under his care who couldn’t control their behaviour the way other children could. Notice that I spelled behaviour the fancy way.
Despite their lack of control, these children were pretty smart. Fred decided he needed to give their lack of behaviour control a description. He didn’t give the best description, at least not by today’s standards. He called it “an abnormal defect of moral control in children.” I don’t like Fred’s description. Do you?
ADHD has nothing to do with morality. Thankfully, we recognize that today. ADHD is caused by the way your brain is built. This is why we now call it neuroatypical. ADHD brains, like mine, differ from what is considered typical.
Many years after Fred’s horrible description, a bunch of other doctors decided they should come to an agreement about what to call different psychological disorders. So, they created the Diagnostic and Statistical Manual of Mental Disorders. V1. At this time, they didn’t think that ADHD/ADD and other forms of neuroatypicality fit into their narrow band of diagnostic characteristics.
By the time they got around to creating their second version, they did recognize the disorder. They called it a “hyperkinetic reaction of childhood.”
I don’t like this name any better than Fred’s. It sounds awful. It also only refers to childhood. What about me? I’m an adult with the disorder. Where do I fit in here?
By 1980, these docs decided to give this disorder a better name. They called it Attention Deficit Disorder. Despite the fact that all the ADHD kids in the 80s were walking around slapping each other with snap bracelets, they didn’t think that hyperactivity was a significant component of the disorder. So, they created 2 subtypes: ADD with hyperactivity and ADD without hyperactivity.
This name feels better to me. However, most of the kids, and some of the adults, I know have some form of hyperactivity. So, it still needed something.
In the late ’80s, given all the slap bracelet welts suffered, the docs decided to change the name to ADHD - Attention Deficit/Hyperactivity Disorder.
They still hadn’t perfected the name, though. Now, individuals who had no hyperactive symptoms were labeled as hyperactive.
In the new millennium, the docs released the 4th edition of the DSM. This time, they included 3 subtypes in the diagnosis. The diagnosis, and the subtypes, remain the same today:
ADHD - Attention Deficit/Hyperactivity Disorder
Or does it? Where does Executive Function fit into this diagnosis?
But that’s a post for another time…
