Quick Answer: How Long Does Post Operative Cognitive Dysfunction Last?

How do you reverse memory loss after anesthesia?

The new findings strongly suggest that the alpha-5 GABA type A receptors are “necessary for the development” of anesthesia-related memory deficits.

They also suggest that drugs to block those receptors are a “plausible strategy for reversing memory deficits after general anesthesia,” the researchers write..

Can anesthesia cause neurological problems?

Operation under general anesthesia in some neurologic disorders requires special precautions to reduce aggravation of the condition. Some of the complications, such as delirium and cognitive impairment, are usually transient, but persisting neurologic deficits may occur.
