Psychosis Has Two Forms: It Can Exist on Its Own, or Be a Symptom of Other Mental Illness or Disease
There is a relationship of some disorders or mental states that are underlying, often unknown, conditions that can be cause for health concern. The main condition know to be associated with psychosis is schizophrenia. However, there are other conditions such as bipolar or borderline personality disorder that have had a higher prevalence of psychosis occurrence. Other things such as pregnancy related depression, disorders of the immune system like HIV or AIDS, lupus, MS, or brain tumors can present increased susceptibility to psychosis as well. Additionally, psychosis-like states can be caused by medications or drugs, such as LSD, amphetamines, or marijuana in certain individuals.
Sometimes, people may only ever have one episode of psychosis. Only in certain conditions do people have an ongoing occurrence of psychotic episodes. This is called brief-psychosis and can last anywhere from several hours to up to one month. In most cases, the disorder is triggered by a major stress or traumatic event, which is called “brief reactive psychosis.” However, it can also occur without a known presence of a stressor as well.
Please know that because people experience psychotic episodes doesn’t mean they are always “psychotic.” In fact, at all other times they are considerably neuro-typical, with lucid thinking and rational behavior after returning to a baseline state of reality.
