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 ...
Authors report resting metabolism in this area is associated with performance on short-term memory tasks. [14] While post-treatment studies suggest significant negative side effects of chemotherapy on cognition, other studies have indicated that there may be baseline vulnerability factors which could contribute to cognitive impairment development.
Symptoms of postperfusion syndrome are subtle and include defects associated with attention, concentration, short-term memory, fine motor function, and speed of mental and motor responses. [1] Studies have shown a high incidence of neurocognitive deficit soon after surgery, but the deficits are often transient with no permanent neurological ...
The former Big Brother presenter has had surgery to remove a colloid cyst, a type of rare fluid-filled benign tumour in the brain. Davina McCall says short-term memory loss is improving after ...
The term "steroid dementia" was coined by Varney et al. (1984) in reference to the effects of long-term glucocorticoid use in 1,500 patients. [3] While the condition generally falls under the classification of Cushing's syndrome , the term "steroid dementia syndrome" is particularly useful because it recognizes both the cause of the syndrome ...
The hippocampus deals largely with memory consolidation, [35] where information from the working memory and short-term memory is encoded into long-term storage for future retrieval. Amnesic patients with damage to the hippocampus are able to demonstrate some degree of unimpaired semantic memory , despite a loss of episodic memory , due to ...
Decades of research has found that exercise is helpful for overall health and fitness, doing everything from lowering your risk of heart disease to helping you sleep better. According to a new ...
Both substance use and alcohol can cause both long-term and short-term memory loss, resulting in blackouts. The most commonly used group of prescription drugs which can produce amnesia are benzodiazepines, especially if combined with alcohol, however, in limited quantities, triazolam (Halcion) is not associated with amnesia or memory impairment.
