Amnesia

Amnesia is a form of memory loss that is usually temporary and affecting short term memory. Common causes and risk factors of amnesia and memory loss include concomitant psychological problems, trauma or head injury and so forth.

What is amnesia?

Amnesia refers to partial or complete memory loss. Becoming forgetful is common and normal as a person ages, however, when memory loss begins to interfere with activities of daily living, it needs to be assessed by a physician to be a sign of a deeper illness.
