Hemichorea-hemiballism (HC-HB) is a complication of non-ketotic hyperglycemia (NKH); in NKH patients, the frequency of occurrence of HC-HB is greater than that of bilateral chorea. We report the case of a hyperglycemic patient who showed chorea in both the lower limbs. Magnetic resonance imaging (MRI) of the brain revealed high signal intensity on T1-weighted images of the bilateral dorsolatera...

This is a unique case of nonketotic hyperglycemic (NKH) chorea in a 34-year-old white male. The patient had a poorly controlled type 2 diabetes mellitus (DM) due to medication incompliance. He complained of polyuria, polydipsia, and weight loss of 20 pounds within a month before presentation. T2-weighted (T2W) MRI showed hyperintensity in the left basal ganglion. Glycated hemoglobin (HBA1c) was...

Benign hereditary chorea (BHC) was originally described in 1967, but it was not until 2002 that linkage analysis and positional cloning identified the causative gene, NKX2-1 (also known as TTF-1).(1,2) The range of manifestations spans from isolated chorea, pulmonary disease, or thyroid dysfunction, with one-third of patients having the full brain-lung-thyroid syndrome.(3) Recent reports have e...

Chorea is a basal-ganglia (BG) related hyperkinetic movement disorder characterized by irregular continuous involuntary movements. Chorea and related hyperbehavioral disorders may be induced in behaving primates by local microinjections of the GABA(A) antagonist bicuculline to the globus pallidus externus (GPe). We performed multielectrode extracellular recordings in the GPe and in the globus p...

Chorea is a movement disorder which may be associated with immunologic diseases, in particular in the presence of antiphospholipid antibodies (aPL). Choreic movements have been linked to the isolated presence of plasmatic aPL, or to primary, or secondary antiphospholipid syndrome. The highest incidence of aPL-related chorea is detected in children and females. The presentation of chorea is usua...

BACKGROUND Sydenham's chorea is the neurologic manifestation of rheumatic fever and is a diagnosis of exclusion requiring only the presence of frank chorea in the absence of another neurologic disorder. Two thirds of children with Sydenham's chorea also have rheumatic carditis (pathologic mitral valve regurgitation). Although there are similar neuropsychiatric symptoms and preceding group A bet...

Chorea and ballism are movement disorders that result from a variety of conditions. They are an uncommon manifestation of diabetes mellitus. We report a 52-year-old diabetic man who presented with acute onset chorea-ballism with a putaminal high-signal-intensity lesion on T1-weighted magnetic resonance imaging (MRI).
