BACKGROUND: Heterogeneity of Parkinson's Disease (PD) phenotype may influence deep brain stimulation (DBS) outcome. However, DBS response in the malignant end of the PD spectrum has been poorly investigated.
OBJECTIVE: To evaluate and compare DBS outcomes in malignant and benign PD patients, defined according to motor and non-motor symptom presentation at the presurgical selection.
METHODS: We categorized a cohort of 154 parkinsonian patients fulfilling criteria for subthalamic nucleus (STN)-DBS into malignant, benign, and intermediate subtypes, according to a recently validated clinical PD classification. DBS efficacy on daily living independence (Schwab and England -S&E-score ≥70%), motor symptoms, and motor fluctuations (Unified Parkinson's Disease Rating Scale -UPDRS- part-III and -IV, and Ambulatory Capacity Measure) were compared between malignant and benign patients, using corrected binary logistic regressions and repeated measure general linear model.
RESULTS: One year after surgery, the probability of losing daily life independence was 16-fold higher in malignant patients, even after adjusting for age at PD onset, PD duration, and percentage of motor improvement after STN-DBS (OR: 16.233; p: 0.035). Conversely, malignant and benign patients showed a similar extent of improvement after STN-DBS (p > 0.05) in motor symptoms, motor fluctuations, and ambulatory capacity, both in medication-ON and medication-OFF conditions.
CONCLUSION: DBS candidates in the malignant end of the PD spectrum may profit from a similar improvement of motor symptoms and fluctuations after STN-DBS when compared to benign PD. However, patients of the malignant group have a lower probability of maintaining independence in daily life early after surgery.
