The Difference Between ADD and ADHD
ADD, or attention-deficit disorder, is an older term for the disorder we now call ADHD, or attention-deficit hyperactivity disorder. It was called ADD up until 1987, when the word “hyperactivity” was added. Some people still use the old term, ADD, out of habit, or because it’s a more familiar term than ADHD. Some use it to refer to kids with ADHD who aren’t hyperactive.
