After suffering a freak accident involving a fencing foil, NA had damage to his left dorsal thalamus, his mamillary bodies (bi-laterally), and his mamillo-thalamic tract.

		+	== Global Amnesia ==
		+	Global amnesia is usually a result of bilateral damage to structures on the internal aspects of the cerebral hemispheres. It is characterized by an inability to learn/retain new information, including verbal, nonverbal, visual, or auditory, as well as a period of retrograde amnesia. Those suffering from Korsakoff's disease as well as patients who survive herpes simplex encephalitis may demonstrate global amnesia.

	Concussion-induced amnesia almost always results in ''temporary'' memory impairment, unless there was organic damage to the brain. A typical case may include both anterograde (after on-set) amnesia and retrograde (before accident) amnesia. A unique feature of concussion amnesia is that memory loss usually is partially recovered with time, although there is nearly always some permanent loss. There may be impairments in the consolidation of new information from short-term to long-term memory.
