Psychotic Disorder Due to Another Medical Condition
Psychotic disorder due to another medical condition is hallucinations or delusions that are caused by another medical disorder.
This diagnosis applies when psychosis is due to the physiologic effects of a medical condition. Examples are psychotic behavior or olfactory hallucinations that are sometimes associated with temporal lobe epilepsy and the contralateral neglect syndrome that is sometimes caused by parietal lobe lesions. Other medical disorders that may cause psychosis include CNS tumors and infections, stroke, migraine, and various endocrine disorders.
The diagnosis is not used if patients have a psychologically mediated response to medical illness (eg, ICU psychosis), psychosis due to the effects of drugs or drug withdrawal, or delirium caused by a medical condition. It is essential to establish a temporal relationship between the medical and psychotic condition (ie, they begin and end at the same time).
Treating the medical condition often reduces the severity of psychotic symptoms, but some patients also need specific treatment of the psychotic symptoms.
