Transiente Globale Amnesie versus Transiente Ischämische Attacke – Klinik und Schlaganfallrisiko

Transient global amnesia versus transient ischaemic attack: clinical presentation and cerebral vascular accident risk Transient global amnesia is an acute, benign, isolated and temporarily limited disturbance of memory, that can occur repeatedly but shows no increased risk of cardiovascular events or stroke in particular. Therefore, patients with the typical clinical presentation and a normal brain magnetic resonance-scan require neither further diagnostic nor therapeutic interventions. Since the differential diagnosis of transient global amnesia is wide, and transient ischaemic attacks can present similarly, a careful clinical evaluation and neuroimaging is recommended. In any case of doubt further diagnostic steps according to stroke workup should be initiated. In contrast, a transient ischaemic attack represents a neurological emergency where clinical and diagnostic evaluation must be introduced fast. The rapid establishment of therapeutic and secondary preventive measures decreases the clearly elevated stroke risk and prevents disability.
