Positive Magnetic Resonance Imaging Evidence of Transient Global Amnesia Following the Use of Sildenafil.

Abstract:

:Transient global amnesia (TGA) has been proposed as a possible adverse effect of sildenafil. There are rare cases in the literature, but none had strong evidence to support. Our case is the first to demonstrate a focal punctate diffusion-weighted imaging lesion at the right hippocampus after the use of sildenafil. This finding, which is suggestive of cytotoxic edema and is typical for TGA, may provide us evidence for the implication of sildenafil in TGA. We speculate that sildenafil may precipitate TGA by altering blood flow, inducing venous congestion or cortical spreading depression at the hippocampus.

  • The reversibility of "permanent" tardive dyskinesia.

    abstract::Neuroleptic-induced tardive dyskinesia (TD) that persists for 1 year or more following withdrawal of neuroleptics is usually said to be permanent. Early spontaneous remissions have been well described but most such remissions occurred within the first few months following neuroleptic withdrawal, and no published studi...
