Mental syndromes secondary to the use of drugs (including alcohol). In dsm-iv-tr, these disorders (except for intoxication and withdrawal) are placed in the diagnostic categories with which they share phenomenology. For example, substance-induced mood disorder is listed under mood disorders, and substance-induced sleep disorder is listed under sleep disorders.
The classifications of substance-induced mental disorders include delirium; dementia; amnestic disorder; psychotic disorder with delusions or hallucinations; mood disorder; anxiety disorder; sleep disorder; and sexual dysfunction.
Substance-induced disorders have a three-part name in dsm-ivtr: the name of the specific substance (e.g., alcohol, cocaine); the context in which symptoms appeared (i.e., intoxication, withdrawal, or persisting beyond these states); and the specific presentation (e.g., mood disorder, anxiety disorder). Examples are alcoholinduced persisting amnestic disorder and cocaine-induced mood disorder with depressive features, with onset during withdrawal.
In dsm-iv-tr, intoxication is recognized for alcohol; amphetamine; caffeine; cannabis; cocaine; hallucinogens; inhalants; opioids; phencyclidine (PCP); sedative, hypnotic, or anxiolytic drugs; and combinations of drugs (polysubstance); withdrawal is recognized for nicotine and all of the above-mentioned substances except caffeine, cannabis, hallucinogens, inhalants, and PCP.
A disorder related to drug use but excluding drug dependency. Substance-induced disorders include intoxication, withdrawal, and other substance-induced mental disorders such as delirium and psychosis.
