Abstract:
In comparison with 27 similar cases, sampled from literature, 4 observations of amnesic episodes in migraine are presented and discussed. These disturbances known as so-called "Migranedammerattacken" seem to be identical with transient global amnesia in all respects. In most of cases, they occur as migraine-precursors or - equivalents. Headache, vegetative und neurological symptoms are frequent but not necessary companions. It is proposed to look for migraine disposition in all cases of transient global amnesia. Perhaps, this approach might be of some use to understand their enigmatic pathogenesis.Keywords:

Twelve patients with transient global amnesia (TGA) had prior migraines (six classical and six common). In three patients, classic migrainous phenomena accompanied TGA, and in nine patients severe headache accompanied the amnestic attack. Migrainous vascular dysfunction in the dominant posterior cerebral artery territory could explain TGA: (1) The pathophysiology and transient nature of TGA have led many to postulate posterior circulation vascular disease; migraine is a vascular disorder with a posterior circulation bias. (2) TGA and migraine share common precipitants. (3) Migraine differs from arteriosclerotic ischemia; the repetitive queries of TGA are absent in amnestic stroke. (4) TGA and migraine are usually benign.

Transient global amnesia, epilepsy, and migraine are three common neurologic disorders likely to be encountered by military physicians. These three entities share many clinical, electroencephalographic, and pathophysiologic characteristics. We report a patient who exemplifies the indistinct boundaries among these conditions and whose response to treatment supports the use of anticonvulsants for selected patients who have recalcitrant migraine.

Transient global amnesia (TGA) is an isolated amnesic syndrome with normal neurological examination where patients remain alert and communicative with no loss of personal identity; however, they experience striking loss of memory for recent events and an impaired ability to retain new information. TGA could be triggered by venous congestion and there is evidence of association between younger patients and history of migraine. Most episodes last 2–12 h and the recurrence rate of future amnesic events is very low.

SYNOPSIS The clinical features of five migraine patients, suffering one to several episodes of transient global amnesia (TGA), were evaluated. All patients were women, with an age range of 34 to 67 years. One patient had common, and four, classical migraine. Two patients had typical vertebro‐basilar migraine; two others had previously experienced transitory neurological symptoms compatible with transitory circulatory disturbances in the vertebro‐basilar arterial system. On the basis of these data and available literature, the pathophysiological mechanisms are discussed. It is suggested that in our patients, TGA was due to transitory ischemia in the mamillo–hippocampal formation, secondary to shortlasting vasospasms in the arteries supplying mesial and basal parts of the temporal lobes. It was concluded that TGA in migraine is a benign condition, and does not usually require extensive neuroradiological investigations.

Transient global amnesia is described in two patients suffering from classical and common migraine, respectively. These cases are peculiar in that the amnesic attack was part of the aura in one patient, while it behaved like an accompanying symptom in the other. The close temporal relation between the attacks of transient global amnesia and migraine strengthens the hypothesis of an etiologic role of migraine. The nature of this mechanism could be the cerebral blood flow changes or the neural perturbation which characterize migraine attacks.

Abstract The presence of magnetic resonance imaging (MRI) abnormalities in patients with transient global amnesia has been an interesting phenomenologic finding. Several theories surround the occurrence of this syndrome, but little is known about its true physiopathology. We present a case of transient global amnesia after cardiac catheterization associated with migraine headache and MRI changes compatible with an ischemic insult. A discussion on potential explanations for this finding is made, as well as a review of the pertinent literature.
