Coughing as a Side Effect of Deep Brain Stimulation due to Peripheral Stimulation of the Vagus Nerve: Case Report
Bibliographic record
Abstract
The authors describe how severe coughing and breathing issues were caused by a deep brain stimulation (DBS) system due to current induction in the adjacent vagus nerve. A 57-year-old man with Parkinson's disease (PD) who received bilateral subthalamic nucleus DBS presented with coughing and breathing difficulty when his DBS system was activated. The intensity of coughing was directly related to the amount of stimulation. When the DBS system was turned off, his cough resolved immediately. A system check revealed no radiographic abnormalities and all electrode impedances were within the normal range. We hypothesize that the coughing was caused by an induced electromagnetic stimulation of the vagus nerve from the extensions, which were running in close proximity to the nerve in the neck. Since the patient could not tolerate the coughing at stimulation settings required to ameliorate his PD symptoms, we ultimately exchanged the extensions and moved them further away from the vagus nerve. This resulted in immediate, complete, and continuous relief of the patient's symptoms.

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.
