	Transient Global Amnesia
		Transient global amnesia (TGA) is a type of amnesia involving the sudden, temporary disturbance in an otherwise healthy person's memory.
		TGA may be the result of a transient ischemic attack, a "mini-stroke." Transient ischemic attacks are caused by a temporary interruption of the blood flow to the brain.
		The symptoms of transient global amnesia seem to be the result of dysfunction in such regions of the brain as the diencephalon and medial temporal lobes.

		Amnesia (or amnaesia in Commonwealth English) is a condition in which memory is disturbed.
		Amnesia may also be spontaneous, in the case of transient global amnesia.
		Traumatic amnesia is often transient; the duration of the amnesia is related to the degree of injury and may give an indication of the prognosis for recovery of other functions.

	Transient global amnesia definition - Medical Dictionary definitions of popular medical terms
		Transient global amnesia: A passing episode of short-term memory loss without other signs or symptoms of neurological impairment.
		In transient global amnesia (TGA) the individual does not lose consciousness but does lose the ability to form new lasting memories.
		The average age of patients with TGA is 62 (range: 47-80) and the mean duration of the episode is 5.7 hours, with a range of 20 minutes to 20 hours.

	Transient Global Amnesia
		Transient Global Amnesia is a syndrome in which a previously well person suddenly becomes confused and amnesic.
		T.G.A. is sometimes precipitated by physical or emotional stress such as sexual intercourse, driving a car, or swimming in cold water.
		T.G.A. affects about one in a thousand people and is more prevalent in males and occurs in middle age or elderly people who are otherwise healthy.

	Transient Global Amnesia - Geriatrics
		Transient global amnesia (TGA) is among the most striking neurologic phenomena known to man. Several hypotheses exist regarding its cause, but there is no consensus among the experts about the underlying basis of transient global amnesia.
		TGA was the term coined for this condition by C.M. Fisher and R.D. Adams over 40 years ago.
		While TGA is considered a benign disorder and is not associated with a history of recent head trauma, patients may experience persistent impairment of mental function.

		Lesions from TIA typically appear larger in size and without delay, in contrast to lesions associated with transient global amnesia.

		The authors favored an ischemic etiology for the TGA in their patients, evidenced by subtle focal motor findings during the events, and the possibility of emboli to the posterior circulation from the aortic vascular lesion.
		I suggest that the onset of TGA in patients with acute ascending aortic dissection is compatible with the venous ischemic hypothesis for TGA that I proposed in 1998.
		In cases of TGA occurring in the setting of acute painful ascending aortic dissection, I suggest that increased venous return to an acutely compressed SVC, causing transient retrograde high- pressured venous flow to bilateral hippocampal or diencephalic structures, is a plausible explanation.

		This was not the first time Dr. Graveline experienced transient global amnesia (TGA), a disease that involves a lapse in the ability to form memory for a period of minutes or hours, sometimes but not always involving the forgetting of past memories, from Lipitor.
		Dr. Graveline was given the diagnosis of "transient global amnesia, cause unknown." He considered various possible causes, and, after eliminating each of them, considered the possibility that Lipitor, a new drug for him, and the only one he was taking, might be the root cause of his problem.
		While transient global amnesia is generally rare, its incidence has exploded since the advent of the strong statin drugs such as Lipitor.

		As the syndrome resolves, the amnesia improves, but the patient may be left with a distinct lapse of recollection for events during the attack.
		Although the patients who presented with a TIA had a higher prevalence of vascular risk factors, those in the TGA group (who had DWI changes) were found to have significantly more carotid atherosclerosis.
		The authors conclude that their findings may indicate that TGA can be associated with neuronal loss in the CA1 region of the hippocampus.
