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 ...
While anesthesia awareness is possible without resulting in any long-term memory of the experience, it is also possible for victims to have awareness with explicit recall, where they can remember the events related to their surgery (intraoperative awareness with explicit recall). [1] [2]
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.
Age-related memory loss can be frustrating and scary. But it doesn’t always mean you’re on the road to dementia. Here’s a look at a few common types of memory lapses, and what to watch out for:
Anesthesia (American English) or anaesthesia (British English) is a state of controlled, temporary loss of sensation or awareness that is induced for medical or veterinary purposes. It may include some or all of analgesia (relief from or prevention of pain), paralysis (muscle relaxation), amnesia (loss of memory), and unconsciousness.
The evaluation of TGA focuses on ruling out other conditions that can cause memory loss: An imaging study (CT or MRI) may be done since (rarely) a bleed into the brain or even a brain tumor can ...
Amnesia is a deficit in memory caused by brain damage or brain diseases, [1] but it can also be temporarily caused by the use of various sedative and hypnotic drugs. The memory can be either wholly or partially lost due to the extent of damage that is caused.
Multiple exposures to anesthesia have been found to confer greater deficits in neurotoxicity, cognition and social behavior than single exposures. [3] Nearly all anesthetics that are antagonists of NMDA receptors and/or agonists of GABA A receptors have been shown to cause developmental neurotoxicity and alter cognition and/or behavior. [4]
