Hyperglycemic chorea/hemiballism ascertained at a large medical center over 15 years: Frequency & characteristics (P2.019)

Conclusions:Hyperglycemia is common, but chorea triggered by hyperglycemia appears to be rare, with only seven cases identified at Mayo-Rochester during 15 years of surveillance. It tended to spare younger people and was primarily seen in later life (median age, 80). In the majority (4/7), it occurred in new-onset diabetes. It may be mistaken for a stroke, given the unilateral presentation (6/7). Although MRI putamen T1-hyperintensity is typical, this was absent in the majority (4/7). This syndrome responds to dopamine blocking or depleting medications.Disclosure: Dr. Ryan has nothing to disclose. Dr. Ahlskog has nothing to disclose. Dr. Savica has nothing to disclose.
