Many things can cause temporary psychosis. Environmental triggers, such as losing a loved one, are known to contribute, as may excessive stress, or the interaction of strong social demands with a pre-existing vulnerability of self.
The compulsive drug user may find their ego dissociating in a psychotic break if habituation means the drug can no longer fulfil its defensive function.
Symptoms of psychotic breaks vary greatly, usually depending on the circumstances of diagnosis or any contributary substance ingested. Symptoms can range from harmless, sometimes unnoticed delusions, to violent outbursts and major depression.
In popular culture
The crime drama television show Criminal Minds features episodes where some killers are suffering from psychotic breaks.
