TRANSIENT GLOBAL AMNESIA AND CONCOMITANT TAKOTSUBO CARDIOMYOPATHY: A CASE SERIES

Transient global amnesia (TGA) is a clinical syndrome characterized by the sudden onset of anterograde amnesia, accompanied by repetitive questioning lasting up to 24 hours with whole restoration and without compromise of other neurologic function. Case reports suggest that cardiac dysfunctions may also occur in patients TGA although until now, no study has systematically assessed this phenomenon. Several pathophysiologic mechanisms have been proposed, with particular emphasis on the role of the central and autonomic nervous systems and an increased sympathetic hyperactivity, likewise to Takotsubo Syndrome (TTS). A case series of two cases (one man and one woman) of TGA as a precocious display of concomitant Takotsubo cardiomyopathy was described.
