Transient Global Amnesia
Causes of Transient Global Amnesia
What causes transient global amnesia is not known. Some experts wonder whether the causes could include seizures, migraines, problems with blood flow in the veins, or temporary blockage of the arteries that supply blood to the temporal lobe (for example, by a blood clot), and/or psychologic factors. However, there is no strong evidence that any of these conditions cause transient global amnesia. Transient global amnesia can be triggered by Sudden immersion in cold or hot water Physical exertion Emotional or psychologic stress Pain Medical procedures Sexual intercourse A Valsalva maneuver (forcefully trying to exhale without letting air escape, as during a bowel movement) However, usually no trigger can be identified. The following can cause symptoms that resemble those of transient global amnesia: Drinking too much alcohol Taking moderately large doses of certain sedatives (such as a barbiturate) Using any of several illicit drugs Sometimes taking relatively small doses of a benzodiazepine (a sedative), especiallymidazolamandtriazolam
