Clinical and Imaging Correlates of Medication Reduction in Globus Pallidus Stimulation for Parkinson's Disease
Bibliographic record
Abstract
BACKGROUND: The magnitude and factors associated with levodopa equivalent daily dose (LEDD) reduction in deep brain stimulation (DBS) of the globus pallidus interna (GPi) for Parkinson's Disease (PD) remain unclear. OBJECTIVE: To investigate LEDD reduction in GPi DBS and its correlation with anatomical/clinical characteristics. METHODS: A consecutive cohort of 74 patients who had undergone GPi DBS was analyzed. Regression and probabilistic efficacy mapping were performed to evaluate factors predicting LEDD reduction. RESULTS: 32.4% of GPi individuals experienced significant LEDD reduction (>30%). Anteromedial GPi stimulation was associated with higher LEDD reduction. CONCLUSION: Anteromedial stimulation of the GPi appears to be associated with medication reduction, challenging the idea that GPi DBS is ineffective at reducing LEDD. Further prospective study will be needed to validate these findings.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
