A worse cognitive status (OR\u200a=\u200a0.966) and less autonomy for activities of daily living (OR \u200a=\u200a 0.937) at V0 and a greater increase in the globalNMS burden (OR \u200a=\u200a 1.011) from V0 to V2 were associated with changing from TD to another phenotype after 2-year follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The MP in PD can change over time.
