Hemichorea-Hemiballism as a Manifestation of Hyperglycemia

Abstract: Hemichorea-hemiballism associated with hyperglycemia is a syndrome characterized by a sudden occurrence of hemichorea, or its more severe expression hemiballism, in patients with non-ketotic hyperglycemia. Hemichorea-hemiballism tends to occur more commonly among elderly people and women of Asian origin. The authors present two rare cases of patients who manifested choreiform and ballistic movements of the limbs and concomitant non-ketotic hyperglycemia. Radiological findings were congruent with hyperglycemia … Show more

“…Involuntary movements in hyperglycaemic syndromes typically involve the limbs; however, they less commonly affect muscles of the jaw and tongue, and usually are unilateral [ 4 ]. Generally, a significant positive correlation exists between the clinical and imaging findings, with radiological changes occurring usually contralateral to the affected limbs [ 3 ].…”

“…Acquired, adult-onset chorea/ballism may be due to several causes. Among those, one of the rarest is the nonketotic hyperglycaemia (NKH), a rare and life-threatening complication of a poorly controlled diabetes mellitus (DM), also defined "Diabetic Striatopathy" (DS), because of common findings detected at the T1-weighted sequences magnetic resonance imaging (MRI) scans-hyperintensity of the striatum/putamen (Maia et al, 2021).…”

“…The onset of the disease presents multiple neurological dysfunctions, especially involuntary movements, including hemiballism and hemichorea. The typical neuroimaging features of the contralateral striatum are hyperdensity on CT scans and hyperintensity on T1-weighted MR images [ 2 , 3 ]. In clinical practice, DS has various manifestations.…”
