Acute hand dystonia and action myoclonus unveiling diabetic striatopathy: The critical role of hyperglycemia.

Diabetic striatopathy is a rare complication of diabetes mellitus characterised by movement disorders secondary to hyperglycemia. While most commonly associated with chorea and ballism, it may also present with other hyperkinetic manifestations, including, albeit rarely, isolated dystonia and myoclonus. We report a case of a patient with poorly controlled diabetes mellitus who developed acute hand dystonia and action myoclonus, highlighting the broader spectrum of hyperglycemia-induced movement disorders.
