Organic Psychosis

An Organic Psychosis is a physical illness, damage to, or deterioration of the brain that results in psychotic symptoms such as visual or auditory hallucinations that are the result of physical illness or brain damage, rather than a psychiatric condition.

The diagnosis for this type of condition is now divided into three categories; delirium, dementia and amnestic. Delirium is a short-term condition that alters the perception of reality such as hallucinations caused by substance use or fever. Dementia is a chronic condition that is caused by the physical deterioration of the brain, such as is caused by Alzheimer's Disease, Amnestic psychosis is psychotic symptoms that are associated with a condition that has caused memory loss.
