Despite being conscious, the...

We report the case of a 62-year-old male on long-term hemodialysis who was admitted to our hospital due to acute cerebral infarction associated with a cardiac calcified amorphous tumor (CAT). The patient presented with recurrent episodes of syncope and retrograde amnesia. Brain MRI identified multiple acute cerebral infarctions, while transthoracic echocardiography (TTE) revealed a 2.5 cm echogenic mobile mass attached to the ventricular side of the posterior mitral leaflet. The patient...

CONCLUSIONS: Similar to previously published studies in civilian populations, older veterans with TBI may be at risk for functional and cognitive decline. This study's findings increase the field's understanding of functional trajectories after TBI in older adults and may help identifty those who are at risk for lower functional outcomes.

The differential diagnosis of acute-onset amnesia includes transient global amnesia (TGA), transient epileptic amnesia (TEA), and functional (or psychogenic) amnesia. The most common of these, TGA, is a rare but well-described condition characterised by a self-limited episode of dense anterograde amnesia with variable retrograde amnesia. Although the clinical phenomenology of TGA is well described, its pathogenesis is not currently understood, thus preventing the development of evidence-based...
