NCT00804479

Brief Summary

To determine the long-term consequences (8 years) of initiating patients with Parkinson's disease on either pramipexole or levodopa. We hypothesize that patients initiating therapy with pramipexole compared with levodopa will demonstrate less self-reported disability as measured by the Modified Schwab and England (S/E) scale 8 years after randomization.

Outcome Measures

Primary Outcomes (1)

  • We hypothesize that patients initiating therapy with pramipexole compared with levodopa will demonstrate less self-reported disability as measured by the Modified Schwab and England.

    8 years from date randomized in CALM study

Secondary Outcomes (1)

  • Our secondary specific aim is to develop and estimate a structural model that will allow us to uncover the causal pathways through which treatments effect outcomes.
