The Diagnostic and Statistical Manuel of Mental Disorders (DSM), by the American Psychiatric Association (APA), is used in the United States to help provide a useful guide for mental health practitioners States diagnose individuals who suffer from Attention Deficit Hyperactivity Disorder and other mental health disorders.


The DSM-5 (2013) separates the Attention Deficit Hyperactivity Disorder (ADHD) into three main categories, and two other categories when the individual does not meet the full criteria of the first three yet has clinically significant symptoms. :


1)     Attention-Deficit/Hyperactivity Disorder, Combined Presentation

2)     Attention-Deficit/Hyperactivity Disorder, Predominantly Inattentive Presentation

3)     Attention-Deficit/Hyperactivity Disorder, Predominantly Hyperactive/Impulsive Presentation

4)     Other Specified Attention-Deficit/Hyperactivity Disorder

5)     Unspecified Attention-Deficit/Hyperactivity Disorder


Combined Presentation, is used to represent an individual meets the criteria for both the Inattention Presentation & Hyperactive-Impulsive Presentation. Predominantly Inattentive Presentation, is used when and individual only meets Inattentive Presentation criteria. Predominantly Hyperactive-Impulsive Presentation, is used when an individual only meets the Hyperactivity-Impulsivity criteria.

The American Psychiatric Society has changed the names used to describe ADHD several times, as our knowledge base has developed the DSM was subsequently updated to improve its utility of diagnosing. In most other countries, the International Classifications of Diseases (ICD) is used to help diagnose individuals with ADHD symptoms and refers to ADHD as Hyperkinetic Disorder, yet they are not completely identical.
