Key Technical Research on the Treatment of Post-stroke Cognitive Impairment With Brain Electric Field Therapy Based on Acupoint Regulation

This clinical study investigates whether electroacupuncture can improve thinking and memory in people with cognitive problems after a stroke (Post-Stroke Cognitive Impairment, or PSCI). Participants will be randomly assigned to one of two groups: one group will receive real electroacupuncture, while the other will receive a sham treatment . Both groups will also receive standard medical care.The main goal is to see if the real electroacupuncture leads to greater improvement in cognitive function tests over 6 months compared to the sham treatment. The study will also use brain scans (MRI) and other assessments to understand how the treatment might work.
