Standard candidacy assessments rely on OFF\u2013ON medication testing and neuropsychological evaluation, which are time\u2010consuming and often unavailable in routine practice. Additionally, traditional UPDRS\u2010based metrics may inadequately capture DBS candidacy across heterogeneous PD motor phenotypes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives<\/jats:title>\n                    <jats:p>The objective of this study is to evaluate a phenotype\u2010specific, longitudinal screening approach to support earlier identification of PD patients who may receive a DBS referral.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Retrospective longitudinal data from the Parkinson's Progression Markers Initiative was used to train supervised logistic regression models to estimate the probability of undergoing DBS during follow\u2010up. Separate models were developed for bradykinesia\/rigidity\u2013predominant, tremor\u2010predominant phenotypes, and the total cohort. Analyses were restricted to visits within a clinically plausible DBS screening window (age\u2009&lt;75\u2009years, Hoehn &amp; Yahr stage 2\u20133, MoCA \u226526). Model performance was assessed using discrimination, threshold\u2010based operating characteristics, calibration, and interpretability via SHAP values.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Across 1,227 patients, phenotype\u2010specific and combined models demonstrated moderate discrimination for eventual DBS implantation (AUC 0.80\u20130.82). In bradykinesia\/rigidity\u2013predominant PD, greater functional impairment and daytime sleepiness consistently increased likelihood of DBS implantation, while higher motor severity reduced referral likelihood. However, in tremor\u2010predominant disease, better cognition and higher motor severity were associated with increased referral likelihood, while impulse\u2010control burden strongly decreased implantation likelihood.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>A phenotype\u2010specific, longitudinal screening approach can stratify DBS referral likelihood in PD.
