Abstract
Hemiballismus- hemi chorea (HB-HC) is an uncommon disorder, mostly seen among the people in Asian region. Recent reports have revealed that it is associated with non-ketotic hyperglycemia. MR spectroscopy in the present study showed a low NAA/Cr, suggesting pronounce energy depletion and neuronal dysfunction. Scientists observed that unilateral lesions occurred in elderly diabetic patients in striatum due to hyperglycemia. Our study reveals that, dyskinesia in elderly diabetic patients leads to an initial manifestation of diabetes among the both sexes.
Highlights
Hemi chorea generally occurs due to a stroke, neoplasm or granuloma in the contra lateral basal ganglia [1]
From May 2008 to September 2009 there were 9 patients admitted with hemichorea. 3 patients (33%) were found to have acute striatal infarcts, 2patients (22%) had granuloma and other four patients(45%) had hyperglycaemia without ketosis
The median age of these 4 patients who had hyperglycemia was 60 years (58 to 70yrs),male to female ratio was 1:1.All were right handed persons.3 patients were known diabetic, their mean duration of diabetes was 12 years. 1 patient was detected to be diabetic at admission
Summary
Hemi chorea generally occurs due to a stroke, neoplasm or granuloma in the contra lateral basal ganglia [1]. Metabolic derangements especially hyperglycemia can cause focal neurological dysfunction like hemiparesis, focal seizure [2,3]. There have been case reports of hemichorea reported due to non-ketotic hyperglycemia with characteristic MRI findings predominantly in the Asian population [4]. The aim of this study is to highlight the important aspects pertaining to the clinical and neuroradiological diagnosis of hemichorea associated with nonketotic hyperglycemia
