Attention Deficit Disorder (ADD)

Attention deficit disorder (ADD) - An outdated term for what experts now call Attention Deficit Hyperactivity Disorder (ADHD).

Experts separated the condition into two subtypes:

  • ADD with hyperactivity
  • ADD without hyperactivity

What’s the Difference Between ADD & ADHD? - While many people continue to use the terms ADD and ADHD interchangeably, it's important to recognize that they are not the same. Here are some key points to be aware of:

  • ADD is an older term for what is now known as the inattentive type of ADHD. 
  • The term ADHD has been used to describe both inattentive and hyperactive types since the mid-1990s.
  • However, some people continue to use the term ADD as a way to indicate that the condition does not include hyperactivity as a symptom.
  • The DSM-5 currently recognizes three subtypes of ADHD: inattentive type (sometimes casually called ADD), hyperactive-impulsive type, and combined type.
