Overview
Amnesia (from Greek Ἀμνησία) is a condition in which memory is disturbed. The causes of amnesia are organic or functional. In simple terms it is the loss of memory. Organic causes include damage to the brain, through trauma or disease, or use of certain (generally sedative) drugs. Functional causes are psychological factors, such as defense mechanisms.
Risk Factors
Normal aging may lead to trouble learning new material or requiring a longer time to remember learned material. However, it does not lead to dramatic memory loss unless diseases are involved.
Memory loss can be seen with impaired concentration, such as with depression. It can be hard to tell the difference.
