Meanings and definitions for POCD
What does POCD stand for? What does POCD mean?
- Postoperative cognitive dysfunction (POCD) is a decline in cognitive function (especially in memory and executive functions) that may last from 1–12 months after surgery, or longer.
- POCD is just as likely to occur after operations under regional anesthesia as under general anesthesia.[2][4]
- More likely after major operations than minor operations.[9][11][12]
- More likely after heart operations than other types of surgery.[9][12]
- More likely in aged than in younger patients.[9][11][12]
- More likely in older patients with high alcohol intake/abuse.[13]
- People with higher preoperative ASA physical status scores are more likely to develop POCD.[9][12]
- People with lower educational level are more likely to develop POCD than those with a higher educational level.[2][9][12]
- People with prior history of a stroke, even though there is complete functional recovery, are more likely to develop POCD.[9][12]
- More likely in the elderly with pre-existing declining mental functions, termed mild cognitive impairment (MCI).[14] MCI is a transitional zone between normal mental function and evident Alzheimer's disease or other forms of dementia. It is insidious, and seldom recognized, except in retrospect after affected persons are evidently demented.
- Delirium[15] and severe worsening of mental function is very likely in those with clinically evident Alzheimer's disease or other forms of dementia, as well as those with a history of delirium after previous operations.[16]
