Abstract
- The differential diagnosis of chorea can be challenging in patients without a family history of Huntington's disease or acute-onset hemichorea with stroke. A 50-year-old woman presented with generalized choreic movements and gait disturbance that first appeared 1 month previously. An extensive diagnostic workup including genetic testing, neuroimaging, and various laboratory investigations revealed that this patient had developed chorea as a result of mercury poisoning. She was treated successfully with chelation therapy.
