Title: Transient Global Amnesia
نویسندگان
چکیده
Transient global amnesia (TGA) is a neurological syndrome characterised by a self-limiting episode of isolated memory impairment. The aetiology of TGA is unknown but it is widely thought not to be an epileptic phenomenon. Nevertheless, epileptic seizures can cause a very similar clinical picture – the syndrome of transient epileptic amnesia (TEA). It is important to distinguish between these two phenomena as their treatment and prognosis are different. In this chapter, we describe the principle clinical features of transient amnesic syndromes, highlighting those that help to distinguish TGA from TEA. We also discuss recent advances that are beginning to unravel the aetiology of TGA.

Transient global amnesia: an extensive case report.
A case of transient global amnesia was studied in detail. Of note was a temporally extensive, although quite patchy, retrograde amnesia during the event for information recallable at other times. While a consolidation block can explain the anterograde amnesia in transient global amnesia, the profound retrograde amnesia requires an additional block in the retrieval of old, established memories.
متن کاملTransient global amnesia: the electroencephalogram at onset.
A middle-aged man experienced onset of transient global amnesia while undergoing an electroencephalogram. No important change in electroencephalographic activity occurred. This case provides evidence against the hypothesis that epileptic discharge is responsible for transient global amnesia.
متن کاملTransient global amnesia mimics: Transient epileptic amnesia
We describe the case of a 79-year-old patient referred for suspected transient global amnesia, after an episode of anterograde amnesia which lasted 90 min. An EEG, performed after the episode, showed bilateral temporal electrographic seizures, orienting the diagnosis toward a transient epileptic amnesia. Transient epileptic amnesia is defined by temporal lobe epilepsy characterized by recurrent...
متن کاملTransient global amnesia in four brothers.
The case histories are described of four brothers who suffered attacks of transient global amnesia. The coincidence of this disorder in four siblings suggests that the causative factors in transient global amnesia may have a familial basis and that its incidence is more common than generally realised.

Objects: Different theories were suggested on the etiopathogenesis of transient global amnesia. Methods: We demonstrate a patient with transient global amnesia, in whom, a transient hyperintense signal change on left hippocampus was detected in diffusionand T2weighted magnetic resonance images. Conclusion: The absence of vascular risk factors or atherosclerotic changes in neuroimaging, in addit...
