It’s not a made up term. It’s real.
Types of Delirium
Hypoactive delirium —> lethargic, sleepy, withdrawn. Seen in encephalopathy (hepatic, metabolic) and benzo intoxication.
Hyperactive delirium —> agitated, hallucinations, delusions, often seen in withdrawal syndromes. Often have a mixed type that alternates between agitated and quiet.
Scary real also. My wife was hospitalized for a sepsis infection and on some very powerful meds. On the fourth day she started suffering what was diagnosed as “Hospital Delirium”
A very frightening event to watch. It peaked when she was in the ICU and lasted just over a day. What was surprising was that the hospital staff did not know what it was and just considered and treated her as a mental problem.
