What are the causes of, and what is the differential diagnosis of, substance-induced mood disorders?
Substance-induced mood disorders are caused by either the intoxication or withdrawal from the substance that is being abused after a significant period of time of intoxication or withdrawal (mood disorder is developed within one month). Sufferers can have manic or depressive symptoms, or have some combination of the two. Before a diagnosis of a substance-induced mood disorder is made, all other factors for the development of the mood disorder have to be ruled out. In the Diagnostic and Statistical Manual of psychological disorders, most of the major mental illnesses have a sub-section defining the substance-induced version of that disorder.
