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).
A person experiencing a TEA episode has very little short-term memory, so that there is profound difficulty remembering events in the past few minutes (anterograde amnesia), or of events in the hours before the onset of the attack, and even memories of important events in recent years may not be accessible during the amnestic event (retrograde amnesia).

The Westmead Post-traumatic Amnesia Scale (WPTAS) is a brief bedside standardised test that measures length of post-traumatic amnesia (PTA) in people with traumatic brain injury. It consists of twelve questions that assess orientation to person, place and time, and ability to consistently retain new information from one day to another.
By introducing an amnesia-inducing drug during this process, the memory can be disrupted. While the memory remains intact, the emotional reaction is damped, making the memory less overwhelming. Researchers believe this drug will help patients with post-traumatic stress disorder be able to better process the trauma without reliving the trauma ...
With weakness or paralysis; With abnormal movement (e.g. tremor, dystonic movement, myoclonus, gait disorder) With swallowing symptoms; With speech symptoms (e.g. dysphonia, slurred speech) With attacks or seizures; With amnesia or memory loss; With special sensory loss symptoms (e.g. visual blindness, olfactory loss, or hearing disturbance)
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 ...
