Causes of Psychosis

23 Jun

Psychosis is often assumed to be caused by Schizophrenia,and when a patient presents to their Doctor or Emergency Room with symptoms of hallucinations,delusions, agitated or bizarre behaviour,the assumption and diagnosis is often of Schizophrenia.
However,many other illnesses can cause behaviour changes or paranoia,and it’s important for the physician to be aware of them,as often the treatment is different for what would be used in Schizophrenia.
In addition,some of these disorders are time critical in nature.
Often,these disorders involve physical symptoms too,however psychosis as the primary symptom has been reported in some cases.
