Diabetic Striatopathy: A Case Report of Two Distinct Presentations in Elderly Patients

Abstract

Movement disorders associated with diabetes mellitus (DM) are rare. The diagnosis of diabetic striatopathy (DS) is based on the presence of a triad characterized by hyperglycemia, hemiballismus/chorea, and hypersignal of the basal ganglia on T1-weighted MRI. In most cases, treatment involves glycemic control. DS should be considered a differential diagnosis in episodes of extrapyramidal movements, especially when associated with hyperglycemia in the elderly. In this paper, we present two cases of DS.
