Hypomagnesemia: A Rare Cause of Movement Disorders, Myopathy and Vertical Nystagmus

The incidence of hypomagnesemia has been reported as 12% among hospital admissions but hypomagnesemia is frequently underdiagnosed. 1 Neurological symptoms include nausea, head-ache, vertigo, cognitive impairment, neuronal hyperexcitability, cerebellar and eye signs. 2,3 We report a patient with hypomagnesemia presenting with ataxia, tremors, myoclonus, downbeat nystagmus (DBN) and proximal myopathy
