title: Reversible antecollis associated with pramipexole in a patient with Parkinson's disease.
abstract: Antecollis is a frequent complication in multiple system atrophy but is rare in Parkinson's disease (PD). We report an 80-year-old patient with a four-year history of PD who developed antecollis six weeks after taking pramipexole (1 mg/day). When assessed in the outpatient clinic, she had antecollis, cogwheel rigidity on the right side, and mild bradykinesia. We found no evidence of myopathic or neurogenic changes in the neck muscles on needle electromyography. We withdrew the pramipexole immediately, and, one week later, her antecollis improved dramatically. This report emphasizes the importance of considering dopamine agonists as a possible cause of antecollis and shows that immediate withdrawal of these drugs may reverse the symptoms.
