The word psychosis was introduced to the psychiatric literature in 1841 by Karl Friedrich Canstatt in his work Handbuch der Medizinischen Klinik. It is based on the clinician's interview with the patient and observations of the patient's behavior over the previous 2–3 days.

Schizophrenia is associated with dopamine imbalances in the brain and may have an underlying genetic cause. [4] Other symptoms may include incoherent speech and behavior that is inappropriate for the situation. [138] Written record of supernatural causes and resultant treatments can be traced back to the New Testament.

Moreover, newer and equally effective antipsychotic drugs actually block slightly less dopamine in the brain than older drugs whilst also blocking 5-HT2A receptors, suggesting the 'dopamine hypothesis' may be oversimplified. The increased adenylate cyclase activity affects genetic expression in the nerve cell, which takes time.
