What causes psychosis?

ANSWER

There are many causes of psychosis. They include too little sleep, some prescription medications, and abuse of alcohol or drugs like marijuana and LSD.

Traumatic events, like the death of a loved one or a sexual assault, can lead to psychosis in people who are vulnerable to it -- so can traumatic brain injuries, brain tumors, strokes, Parkinson’s disease, and Alzheimer’s disease.

Psychosis can also be a symptom of a mental illness, like schizophrenia or bipolar disorder.
