The third and fourth editions of the Diagnostic and Statistical Manual of Mental Disorders (DSM) organized psychopathology using a "multiaxial" system, and describes the axes as "different domains of information" for use in clinical work. The American Psychiatric Association did away with the axis system for the DSM-5 because it could be duplicative and confusing.[1]

"Axis II" includes personality disorders and intellectual disability, and more generally is used to describe maladaptive aspects of personality, and defense mechanisms.

The five DSM axes are:[2]

Within Axis II, 12 conditions are distinguished (many are commonly referred to by their acronyms):

  1. Paranoid Personality Disorder
  2. Schizoid Personality Disorder
  3. Schizotypal Personality Disorder
  4. Antisocial Personality Disorder
  5. Borderline Personality Disorder
  6. Histrionic Personality Disorder
  7. Narcissistic Personality Disorder
  8. Avoidant Personality Disorder
  9. Dependent Personality Disorder
  10. Obsessive-Compulsive Personality Disorder
  11. Personality Disorder Not Otherwise Specified
  12. Intellectual disability (formerly known as "mental retardation")

These conditions are not mutually exclusive. The DSM notes that it is common for a patient to have more than one Axis II condition.
