Common Causes Of Amnesia

Anoxia

Anoxia is a condition in which an organ does not get any oxygen for a certain period. When the affected organ is the brain or part of the brain, it is referred to as cerebral anoxia or anoxic brain injury. Permanent neurological damage often occurs from this. There are many possible causes of a lack of oxygen in the brain, including various lung diseases, severe anemia, hemorrhaging, carbon monoxide poisoning, and cardiac arrest. It can also occur if someone is in an environment where there is simply not enough oxygen in the air, such as at very high altitudes or underwater. Amnesia is a common result of the brain damage that occurs when the brain does not get enough oxygen. Whether a patient regains normal memory function depends on how severe the anoxic brain injury is. If the damage is mild, the patient may actually make a full recovery. However, many patients' prognoses are very poor.
