The electric brain: approach to suboptimal DBS parameters
Bibliographic record
Abstract
• Programming errors underlie 40% of post-DBS patient dissatisfaction cases. • Chronic stimulation correction requires tolerance-optimized protocols. • Suboptimal leads: directional steering enables gradual VTA correction. • High-TEED cases: 10–15% weekly energy reduction prevents rebound. • Misplaced leads: Structured deactivation precedes revision decisions. Deep Brain Stimulation (DBS) has revolutionized Parkinson’s disease treatment, yet post-operative challenges persist, including reversible programming errors caused by insufficient clinician training. Approximately 40 % of suboptimal outcomes referred to tertiary centers stem from correctable programming errors, highlighting the need for standardized approaches [ 1 ]. This article addresses chronic overstimulation syndrome in Subthalamic DBS(STN-DBS), where patients with sustained high-energy stimulation leads poorly tolerated rebound effects when abruptly adjusted. We present a structured, image-guided algorithm combining gradual energy titration with advanced volume of tissue activated (VTA) modeling to optimize therapeutic windows. Three characteristic scenarios are detailed: (1) suboptimal lead placement, managed via directional steering to refine stimulation focus; (2) excessive stimulation energy, addressed through decremental total electrical energy delivered (TEED) reduction; and (3) misplaced leads, requiring systematic deactivation and candidacy assessment for surgical revision. Our tolerance-optimized framework emphasizes spatial precision (leveraging imaging reconstruction) and temporal adaptation (gradual parameter adjustments), offering a paradigm shift for managing chronic DBS complications. While focused on STN-DBS, these principles may extend to other targets facing analogous challenges. The integration of advanced imaging with clinician expertise underscores the dual importance of technology and specialized training in improving DBS outcomes.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
