Stroke mimic caused by severe hypomagnesemia: a case report and literature review.

Association of hypomagnesemia and neurological deficits is a well documented issue, but despite its importance, magnesium levels are rarely tested during the acute phase of a stroke. Focal neurological deficits have rarely been ascribed to hypomagnesemia. We report the case of a patient treated with Proton Pump Inhibitors and Metformin with a history of unexplained transient neurological deficits who developed stroke-like symptoms of hemiparesis and aphasia with recovery after correction of his hypomagnesemia. We also present a brief literature review regarding Magnesium's role in focal neurological deficits.
