Abstract
Subacute-to-chronic gait instability has a broad differential diagnosis. The neurological exam can help elucidate the localization and suggest an underlying etiology of the symptomatology, which can lead to a more focused diagnostic approach. Two patients are described - 1 with a month of worsening difficulty with ambulation that evolved to bilateral hand discoordination and another with 18months of progressive difficulty with ambulation that also then progressed to involve her bilateral hands. These cases highlight an approach to gait dysfunction with hand discoordination secondary to sensory ataxia. The patients were ultimately diagnosed with copper deficiency myelopathy secondary to zinc excess, and different treatment regimens are discussed.
