title: Short-term paroxetine treatment does not alter the motor response to levodopa in PD.
abstract: The authors examined the motor effects of 2 weeks of paroxetine, a serotonin reuptake inhibitor (SSRI), and placebo on responses to 2-hour levodopa infusions in 14 subjects with Parkinson disease. Paroxetine did not affect tapping scores or dyskinesia. Baseline walking speed (preinfusion) increased on paroxetine, often associated with an increased subjective perception of worsened balance.
