Organic Amnesia: A Diversity in Deficits

Organic amnesia is the loss of memory due to biological factors such as brain disorders, tumors, strokes, degenerative diseases, or any other of a multitude of other disruptions of neurological function. Memories are stored throughout the brain, and as a result damage to any localized brain region only causes limited memory deficits. Even in itself, organic amnesia can present in a variety of impairments across numerous memory systems within the brain. Several kinds of amnesia will be reviewed, including details of the corresponding deficits and suggestions of the likely affected memory system.
