N: 1. “loss of memory,” 1786 (as a Greek word in English from 1670s), Modern Latin, coined from Greek amnesia “forgetfulness,” from a-, privative prefix, “not” + stem from mnasthai “to recall, remember,” related to mnemnon “mindful,” mneme “memory;” from PIE root *men- “to think, remember” (see mind (n.)).
2. Amnesia, loss of memory occurring most often as a result of damage to the brain from trauma, stroke, Alzheimer disease, alcohol and drug toxicity, or infection. Amnesia may be anterograde, in which events following the causative trauma or disease are forgotten, or retrograde, in which events preceding the causative event are forgotten.
3. The condition also may be traced to severe emotional shock, in which case personal memories (e.g., identity) are affected. Such amnesia seems to represent a psychological escape from or denial of memories that might cause anxiety.
