The 4th edition of the Diagnostic and Statistical Manual of Mental Disorders(DSM-IV) organizes all psychiatric disorders and other problems into five different categoris (or axes).
For example, Axis I disorders include:
- Anxiety Disorders(e.g.,panic disorder, social anxiety disorder,posttraumatic stress disorder)
- Mood Disorders (e.g., major depression, bipolar disorder)
- Eating Disorders (e.g., anorexia nervosa, bulimia nervosa)
- Psychotic Disorders
- Dissociative Disorders
- Substance Use Disorders
Personality disorders (e.g., borderline personality disorder) are not included on Axis I. Instead, they are considered Axis II disorders.
