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.

Like EA1, attacks can be precipitated by exercise, emotional stress/agitation, physical stress, or heat (overheated body temperature) but also by coffee and alcohol. EA2 is caused by mutations in CACNA1A , which encodes the P/Q-type voltage-gated calcium channel Ca V 2.1, and is also the gene responsible for causing spinocerebellar ataxia type ...
Various parts of the brain may keep functioning when others do not anymore, and the term "brain death" has been used to refer to various combinations. For example, although one major medical dictionary considers "brain death" to be synonymous with "cerebral death" (death of the cerebrum ), [ 8 ] the US National Library of Medicine Medical ...
Perioperative mortality has been defined as any death, regardless of cause, occurring within 30 days after surgery in or out of the hospital. [1] Globally, 4.2 million people are estimated to die within 30 days of surgery each year. [2]
