Dementia prevalence and incidence were not higher over time in Parkinson's disease patients who had deep-brain stimulation than in the general Parkinson's population, a retrospective single-center study in France suggested.
Among Parkinson's disease patients who had subthalamic nucleus DBS, dementia prevalence was 2.3% at one year, 8.5% at five years and 29.8% at 10 years, reported Elena Moro, M.D., of Grenoble Alpes University, and co-authors.
