Congrats on your diagnosis! ADD is not a medically valid term anymore. Just as we no longer refer to PTSD as shell shock.
ADHD has three types:
- Hyperactive/impulsive
- Inattentive
- Combined
So your diagnosis would be inattentive ADHD. (Same here)
Here's an article on the matter.
Also, I'm a huge proponent of the name being changed entirely to Executive Function Disorder. ADHD is a total misnomer. I'm not hyperactive, and, I constantly get distracted by focusing on something I shouldn't be for 12+ hours at a time, I certainly am not deficient in attention. I have plenty of attention to give, but my body lacks the natural reward system that would allow me to choose where that attention goes. Executive Function Disorder is more descriptive and accurate. And that doesn't even take into consideration that changing the name would also help to remove decades of negative bias regarding ADHD and the perception of those who have it having had a moral failing because they can't concentrate.
