This was the first measure created to test post-traumatic amnesia, and is still the most widely used test. [1] The test was created by Harvey S. Levin and colleagues (1979), and features ten questions that assess temporal and spatial orientation, biographical recall, and memory. [2]
New research has been carried out to test what people can remember after a general anesthetic, in an effort to understand anesthesia awareness more clearly and help to protect patients from experiencing it. A memory is not one simple entity; it is a system of many intricate details and networks.
The purpose of anesthesia can be distilled down to three basic goals or endpoints: [2]: 236 hypnosis (a temporary loss of consciousness and with it a loss of memory.In a pharmacological context, the word hypnosis usually has this technical meaning, in contrast to its more familiar lay or psychological meaning of an altered state of consciousness not necessarily caused by drugs—see hypnosis).
MAC is used to compare the strengths, or potency, of anaesthetic vapours. [1] The concept of MAC was first introduced in 1965. [2] MAC actually is a median value, not a minimum as term implies. The original paper proposed MAC as the minimal alveolar concentration, [3] which was shortly thereafter revised to minimum alveolar concentration. [4]
Korsakoff syndrome (KS) [1] is a disorder of the central nervous system characterized by amnesia, deficits in explicit memory, and confabulation.This neurological disorder is caused by a deficiency of thiamine (vitamin B 1) in the brain, and it is typically associated with and exacerbated by the prolonged, excessive ingestion of alcohol.

Drug-induced amnesia is amnesia caused by drugs. Amnesia may be therapeutic for medical treatment or for medical procedures, or it may be a side-effect of a drug, such as alcohol, or certain medications for psychiatric disorders, such as benzodiazepines. [1] It is seen also with slow acting parenteral general anaesthetics. [citation needed]
Various drugs are used to achieve unconsciousness, amnesia, analgesia, loss of reflexes of the autonomic nervous system, and in some cases paralysis of skeletal muscles. The best combination of anaesthetics for a given patient and procedure is chosen by an anaesthetist or other specialist in consultation with the patient and the surgeon or ...
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. [2] There are two main types of amnesia:
