organic psychosis

mental disorder

Quick Summary

Organic psychosis refers to mental dysfunction stemming from physical changes in brain structure, leading to impaired cognition. This contrasts with functional psychoses, where no clear physical abnormality is identified. Organic psychoses can be acute or chronic and are characterized by symptoms like delusions and hallucinations.12

Causes of organic psychosis include diseases affecting the brain, such as dementia (like Alzheimer's disease), delirium, head injuries, brain tumors, epilepsy, and Parkinson's disease. Additionally, certain drugs, including medications for pain, inflammation, or heart conditions, and substances of abuse like alcohol and cocaine, can alter brain function and induce psychotic symptoms. Treatment focuses on addressing both the symptoms and the underlying physical cause.23
