Psychosis is a neurological syndrome associated with abnormal functioning of the frontal and temporal lobes and the dopaminergic projections to these areas. Symptoms develop when a threshold level of damage is reached, or changes occur in these areas of the brain. People with psychosis may experience hallucinations, delusions, disorganised thoughts and actions, and may have personality changes. Psychosis can be due to primary disorders or may have secondary causes. [1] Primary psychotic disorders include schizophrenia, delusional disorder, schizoaffective disorder, schizophreniform disorder, and brief psychotic disorder. Secondary psychosis has many causes, including psychoactive drugs and general medical conditions. It may also accompany another psychiatric condition.
