Causes, incidence, and risk factors
Psychosis is a severe mental condition characterized by a loss of contact with reality. There are numerous potential causes:
- alcohol and certain drugs can induce psychosis
- bipolar disorder (manic depression)
- brain tumors
- epilepsy
- psychotic depression
- schizophrenia
- dementia (Alzheimer's and other degenerative brain disorders)
- stroke
Symptoms
- loss of touch with reality
- seeing, hearing, feeling, or otherwise perceiving things that are not there (hallucinations)
- disorganized thought and/or speech
- emotion is exhibited in an abnormal manner
- extreme excitement (mania)
- confusion
- depression and sometimes suicidal thoughts
- unfounded fear/suspicion
- mistaken perceptions (illusions)
- false beliefs (delusions)
Signs and tests
Psychological evaluation and testing helps to pinpoint the exact diagnosis related to the psychosis.
Laboratory or radiological testing is usually not helpful. However, sometimes such tests can help to pinpoint the exact diagnosis. This may include:
- MRI of the brain
- tests for syphilis
- drug screens
Treatment
Treatment varies depending on the cause of the psychosis. Care in a hospital is often needed to ensure safety of the patient. Drugs that diminish auditory hallucinations and delusions and stabilize thinking and behavior (antipsychotic drugs) are helpful. Group or individual therapy can also be useful.
