Krishnan et al.,[1] have presented an excellent article focusing on the predictors of dementia-free survival after bilateral subthalamic deep brain stimulation (STN-DBS) in Parkinson’s disease (PD). In this analysis of 116 patients, with a 542-person year follow-up, operated with a mean duration of PD prior to undergoing surgery of 11.2 (±4.2) years, 30 patients developed dementia. The mean dementia-free survival after surgery was 8.7 years.
