Delusions and Hallucinations
Does the patient have any delusional thought processes? Does he have auditory or visual hallucinations? Ask questions such as, "Do you ever hear things that other people don't hear or see things that other people don't see?" "Do you feel that someone is watching you or trying to hurt you?" "Do you have any special abilities or powers?"
What is Being Tested?
These abnormalities can be seen in toxic or metabolic abnormalities and other causes of diffuse brain dysfunction, and in primary psychiatric disorders. In addition, abnormal sensory phenomena can be caused by focal lesions or seizures in visual, somatosensory, or auditory cortex, and thought disorders can be caused by lesions in the association cortex and limbic system.
