Hemichorea-hemiballismus developing due to non-ketotic hyperglycemia: A rare case report

Hemichorea-hemiballismus can be seen as a rare complication of non-ketotic hyperglycemia in patients with type 2 diabetes mellitus. We detected hemichorea-hemiballismus secondary to hyperglycemia in a patient who presented to the emergency department with speech disorder and involuntary movements in the left arm, as a result of our investigations. We decided to present this case because it is rare in the literature.
