There's a lot of confusion about what is ADD and ADHD. Before we begin with the differences, let's learn the definition first. ADD stands for attention deficit disorder while ADHD stands for attention deficit hyperactivity disorder. We should keep in mind that the name has changed. In the past few years, the DSM-5 has made some changes. While ADDD used to define people that were inattentive and ADHD defined as people that were hyperactive, that is no longer the case. The DSM-5 now states that ADHD is the only medically accepted term that defines people with this disorder, whether they represent physical hyperactivity or not.
You do not have to have physical hyperactivity in order to have ADHD, physical being the keyword here. You could have internal hyperactivity. People with inattentive type ADHD often report that they are unable to regulate their attention, unable to regulate where their thoughts go and how fast they are going. That would describe internal hyperactivity. You don’t have to be bouncing off the walls and fidgeting with something to be classified as hyperactive. So, in short, ADD is not a thing anymore. Anyone that has a disorder has ADHD not ADD. However, ADHD has 3 different subtypes, those are:
- Hyperactive-impulsive (ADHD-HI)
- Inattentive (ADHD-PI)
- Combined (ADHD-C)
