Abstract:
INTRODUCTION: Nonketotic hyperglycemia among type 2 diabetic patients have recently been documented to cause the rare movement disorder called Hemichorea-hemiballism syndrome which is a hyperkinetic movement disorder presenting as a continuous, non-patterned, involuntary movements caused by a basal ganglia dysfunction.
METHODS: A 76-year-old male with a known history of hypertension and no history of stroke and diabetes presented with a 10-day history of increasingly persistent involuntary movements of the right extremities. On admission, the patient was conscious with stable vital signs and unremarkable neurologic findings except for the involuntary flailing movements of the right extremities. Diagnostic testing revealed first documentation of hyperglycemia with brain MRI changes on T1 hyperintensity signals on the basal ganglia and T2/FLAIR weighted imaging showing mixed hypointense and hyperintense signals which is a classical MRI finding in patients with HC-HB syndrome caused by nonketotic hyperglycemia. The patient was treated for diabetes and was maintained on anti-dopaminergic medications for the uncontrollable involuntary movements. After five months, resolution of the hemiballism-hemichorea syndrome was noted after appropriate treatment.
CONCLUSION: This case report highlights hemichoreahemiballism syndrome in a newly diagnosed type 2 diabetic patient who had normal glucose levels at presentation. The prompt recognition and correction of uncontrolled newly diagnosed diabetes and administration of anti-dopamine agents lead to a rapid improvement of symptoms, less neurologic sequelae and an overall favorable prognosis.
