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. [1] In some cases, this disorder may persist for several years after major surgery. [2] POCD is distinct from emergence delirium. Its causes are under ...
This approach is called a "recall test" because patients are asked to recall any memories they had during surgery. Implicit memory or unconscious memory, which refers to the changes in performance or behavior that are produced by previous experiences but without any conscious recollection of those experiences. An example of this is a ...
EF exhibited memory loss of his personal experiences (e.g., childhood), and the impaired ability to recognize his wife and parents. [47] JG is the first recorded patient with isolated RA. [10] GH, a mother and a wife, had surgery in August 2002. When GH woke up after the surgery, she believed it was May 1989. [47]
Davina McCall says her post-surgery short-term memory loss is “really improving a lot every day” as she recovers at home from a brain operation. The former Big Brother presenter, 57, known for ...
After an ischemic episode (reduction of blood to the brain) that was caused from a heart bypass surgery, R.B. demonstrated a loss of anterograde memory, but almost no loss of retrograde memory, with the exception of a couple of years before his surgery, and presented no sign of any other cognitive impairment.
When C.L. came to Vicari et al.'s office, her chief complaint was forgetfulness involving both semantic and episodic memory. After administering a battery of neuropsychological tests, Vicari determined that C.L. performed well in tests of visual naming and sentence comprehension, visual-spatial ability, and "general semantic knowledge about the ...
Amnesia is desirable during surgery, so general anaesthesia procedures are designed to induce it for the duration of the operation. Sedatives such as benzodiazepines, which are commonly used for anxiety disorders, can reduce the encoding of new memories, particularly in high doses (for example, prior to surgery in order for a person not to recall the surgery). [2]
The incidence of emergence delirium after halothane, isoflurane, sevoflurane or desflurane ranges from 2–55%. [10] Most emergence delirium in the literature describes agitated emergence. Unless a delirium detection tool is used, it is difficult to distinguish if the agitated emergence from anesthesia was from delirium or pain or fear, etc.
