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 ...
The authors concluded patients with long-standing coronary artery disease have some degree of cognitive dysfunction secondary to cerebrovascular disease before surgery; there is no evidence the cognitive test performance of bypass surgery patients differed from similar control groups with coronary artery disease over a 12-month follow-up period.
This area is on the floor of the fourth ventricle and is effectively outside of the blood-brain barrier, which makes it incredibly sensitive to toxin and pharmacological stimulation. Several neurotransmitters are known, such as histamine, dopamine, serotonin, acetylcholine, and the more recently discovered neurokinin-1 (substance P).
Hemispherectomy is a surgery that is performed by a neurosurgeon where an unhealthy hemisphere of the brain is disconnected or removed. There are two types of hemispherectomy. Functional hemispherectomy refers to when the diseased brain is simply disconnected so that it can no longer send signals to the rest of the brain and body.
Visual analog scores (VAS) were obtained before and after injection to measure effectiveness. When compared, VAS scores improved from an average of 7.8 to 2.8 after the procedure. Most complications that occurred from this procedure consisted of nausea and drowsiness. These symptoms went away after the pump was adjusted.
Scientists have managed to make death even scarier. According to a team of scientists in New York, the human brain is still very active after death, which means there's a chance you could actually ...
[8] Some aspects of surgery that can add to chaos are performing unforeseen changes in the procedure and undergoing emergency surgery. [14] Consequently, the emergency room is the place most likely to make mistakes. [15] Studies have shown having a high body mass index increases risk. Boston researchers found that a one-point increase in BMI ...
After testing it on pigs, Vrselja and his colleagues are now studying donated human brains with their machine, BrainEx. It’s a more delicate operation than the pig experiments, and poses grave ...
