Abstract
Purpose/aim: Retrocollis can substantially disturb the daily living of individuals with Parkinson’s disease (PD). Clinician often encounter the difficulty in managing the retrocollis.
Materials and Methods: We describe a patient with PD who presented with choreic dyskinesia and levodopa-responsive retrocollis.
Results: The patient had dyskinesia and the off periods, and received levodopa (700 mg, 14 times/day). The patient received levodopa–carbidopa intestinal gel (LCIG) treatment. After several months, the patient complained of difficulty in swallowing and speech due to severe retrocollis. Thirty minutes following a fast levodopa infusion of LCIG, the retrocollis improved. As a result, a frontal view was obtained, and her talking abilities showed improvement.
Conclusions: Severe retrocollis can be superimposed on choreic dyskinesia, and it was likely to increase during the off periods. Duodenal levodopa infusion may reduce the severity of retrocollis.
