Movement disorders are well-known presenting signs of metabolic disorders. Focal motor abnormalities may be the chief initial presentation of diabetes mellitus in the nonketotic hyperglycemic state in 6% of patients. Nonketotic hyperglycemia (NKH), in particular, may manifest any of a wide variety of movement disorders. These have been described as focal seizures, epilepsia partialis continua, myoclonus, and opsoclonia. There are descriptions of movement disorders in hyperglycemia that are similar to the coarse flapping tremor of asterixis, the posturing of paroxysmal kinetogenic choreoathetosis, and of "fencing (stance) seizures." Disorders of facial motor function including aphasia, facial muscle twitching and jerking, and disorders of muscular tone have been described. These may include hemiparesis and hemiplegias as well as increased tone, in some cases mimicking the nuchal rigidity of meningitis. The movement disorders in NKH may mimic cerebral vascular accidents, meningitis, or psychiatric disorders, as well as various types of seizures. Clinicians may be able to avoid expensive and time-consuming diagnostic evaluations to rule out NKH in patients with movement disorders. We present two patients with focal motor abnormalities associated with nonketonic hyperglycemia and review the pertinent literature.
