This study evaluates a non-invasive electrical stimulation therapy applied to specific acupoints on the fingers (called Jing-Well points) to improve thinking and memory problems after stroke.
Purpose: Many stroke survivors develop cognitive difficulties (problems with memory, attention, and decision-making). Current treatments are limited. This study tests whether gentle electrical stimulation to hand acupoints can improve these symptoms.
Who can participate: Adults aged \[35-80\] who have had an ischemic stroke and now have mild to moderate cognitive impairment.
What happens: Participants will be randomly assigned to receive either (1) active electrical stimulation to hand Jing-Well points, (2) sham (fake) stimulation. Treatment will last 4 weeks, 6 sessions per week, each 30 minutes, with a stimulation frequency of 10 Hz and intensity adjusted to each participant's tolerance. Cognitive tests and brain imaging will be done before and after treatment.
Potential benefits: Participants may experience improved cognitive function. The study will also help researchers understand how this therapy works in the brain.
Risks: The electrical stimulation may cause mild tingling or skin irritation at the electrode sites. Brain imaging is non-invasive and safe. All procedures will be performed by trained professionals.
