Abstract: Background Treatment for Parkinson's disease (PD) is symptomatic. Surgical treatment with continuous high-frequency stimulation of the subthalamic nucleus ( STN- DBS) is established as a safe symptomatic treatment with long-term beneficial effects. It has been postulated that STN- DBS could halt the progression of PD through a disease modifying or neuroprotective effect. Objective To investigate the postulated disease modifying or neuroprotective effect of STN- DBS by comparing the rate of deterioration of parkinsonism and mortality over time in two selected and matched groups of patients with PD with and without surgery. Methods Group A was derived from all patients who received STN- DSB surgery at Oslo University Hospital, from January 2001 to December 2007. Group B was derived from a prevalence study of PD in the Stavanger area of Western Norway in 1993. The two groups were individually matched and the disease progression measured by Unified Parkinson's Disease Rating Scale-motor scores, and the mortality was compared. Results The mean annual change based on baseline and last observation scores in individually matched groups was 0.97 ( SD = 3.57) for the surgery group and 1.04 ( SD = 3.33) for the controls and thus not significantly different, F(1, 104) = .21, P = 0.89. The long-term mortality was also similar in the two groups during long-term follow-up, hazard ratio = 1.76, CL 0.91-3.40, P = 0.091. Conclusion This study gives no support to a postulated disease modifying or neuroprotective effect of STN- DBS in patients with PD. [ABSTRACT FROM AUTHOR]
