Attention Deficit Disorder (ADD) is the same thing as Attention Deficit Hyperactivity Disorder (ADHD). It is a common misconception that ADD and ADHD reflect two types of attention-related problems. So, why do we have two different names for the same disorder? The use of two different names for the same disorder developed in large part out of evolving beliefs about the causes of the condition and differing approaches to diagnosis. When determining a formal diagnosis following an ADD test, most psychologists rely on a diagnostic manual that calls the overall condition Attention Deficit Hyperactivity Disorder, yet provides sub-categories to more precisely characterize an individual’s particular issues. The sub-categories are: Predominantly Inattentive Type, Predominantly Hyperactive Type, and Combined Type, the latter indicating that an individual has both inattention and hyperactivity problems.

However, medical doctors and some psychiatrists may use different terminology because they rely on a different manual for determining diagnostic labels. Psychiatrists and other medical doctors may use either the term Hyperkinetic Syndrome of Childhood or Attention Deficit Disorder, perhaps also using more specific sub-types to further clarify the nature of an individual’s problems in a test for ADD.
