When people get really, really depressed, they can become psychotic. I had a patient at UCLA last year who was a woman in her 80s.
Over a period of months prior to her hospitalization she became increasingly depressed.
For example, a brain tumor pushing on the visual cortex might lead to visual hallucinations.
She’ll attribute small, insignificant things, such as seeing a door left ajar or there being less milk left in the fridge than she remembers, as evidence of her delusion.
Sometimes a person has psychotic symptoms because of a physical, rather than mental illness.
The word “crazy” means different things to different people. However, there is a much more interesting, much more dangerous form of crazy – psychosis.
Your ex girlfriend is crazy (or at least she has a personality disorder).
Delirium is a condition very common in medical ill people (such as patients with infections, metabolic abnormalities, or who recently had surgery) that results in confusion, disorientation, and often hallucinations or delusions.
The term “ICU psychosis” (not actually a medical diagnosis) refers to the delirium that commonly occurs when a patient is in the ICU.
For example, people may here voices telling them they’re a bad person, or that they should hurt themselves.
They may have delusional beliefs about people trying to punish them.
When people are manic, they often become psychotic.
