Using simple assessment scales and blood test data, we developed ten machine learning algorithms to predict PD-MCI. The optimal model was determined through comparison, and its performance was evaluated using an external validation cohort of 139 PD patients from a Taihe state hospital in Shiyan City, Hubei Province.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The area under the receiver operating characteristic curve (AUC) for the ten models ranged from 0.57 to 0.72.
