Neuroscientists have demonstrated that theta-frequency deep brain stimulation targeting basal ganglia areas can improve conflict resolution and cognitive functions in Parkinson’s disease patients. This novel neuromodulation strategy, detailed by researchers Xie, Bai, and Zhuang, represents a potential therapeutic avenue addressing non-motor symptoms, which significantly impact quality of life. The findings support further exploration of frequency-specific DBS protocols to optimize cognitive outcomes alongside motor control in Parkinson’s treatment.
