Functional changes in temporal lobe activity during transient global amnesia.

Published

Journal Article

The integrity of temporal lobe activity during and after recovery from transient global amnesia (TGA) was assessed in a case study using functional MRI. TGA was associated with scene-encoding deficits in a temporolimbic circuit that recovered over time. Frontoparietal areas recruited during the amnesic state may signify a compensatory reliance on visuospatial or working memory strategies. Reduction of extrastriate cortex responses over repeated testing sessions possibly indicates intact visual priming in TGA.
