Chorea - Is Diabetes Mellitus the Cause?

Diabetic striatopathy (DS) is an uncommon complication of diabetes characterized by hemiballismus-hemichorea, often accompanied by reversible striatal hyperintensity on neuroimaging. Diabetes is the most common metabolic cause of hemiballismus and hemichorea. However, it is underreported as clinicians do not always consider it in the diagnosis of new movement abnormalities.

A Novel Generalized Lipodystrophy-Associated Progeroid Syndrome Due to Recurrent Heterozygous LMNA p.T10I Mutation.

Background: Lamin A/C (LMNA) gene mutations cause a heterogeneous group of progeroid disorders, including Hutchinson-Gilford progeria syndrome, mandibuloacral dysplasia, and atypical progeroid syndrome (APS). Five of the 31 previously reported patients with APS harbored a recurrent de novo heterozygous LMNA p.T10I mutation.
