Diabetic Striatopathy (Hyperglycemic Hemichorea-Hemiballismus Syndrome) in a Young Patient with Type 1 Diabetes Mellitus in Dar es Salaam, Tanzania: A Case Report.

Introduction: Diabetic striatopathy, or nonketotic hyperglycemic hemichorea-hemiballismus syndrome, is a rare movement disorder linked to poorly controlled diabetes mellitus. It predominantly affects older women with type 2 diabetes mellitus and presents with characteristic basal ganglia abnormalities on computed tomography (CT) and magnetic resonance imaging (MRI). Even rarer is the presentation in a young patient, which may pose diagnostic and management challenges.
