title: Chorea-ballism as a manifestation of decompensated type 2 diabetes mellitus.
abstract: Chorea and ballism are movement disorders that result from a variety of conditions. Hyperglycemia is an unusual recognized cause of these movement disorders. We report 3 cases of new-onset chorea-ballism induced by nonketotic hyperglycemia in elderly patients, highlighting that chorea may be the first manifestation of undiagnosed decompensated diabetes mellitus.
