Brief Summary:
This randomized, double-blind, sham-controlled trial aims to evaluate the effect of remote ischemic conditioning (RIC) on cognitive function in patients with cerebral small vessel disease-related mild cognitive impairment. Forty eligible participants will be randomized 1:1 to receive either RIC or sham RIC twice daily for 90 days in addition to standard medical therapy. The primary outcome is the change in Montreal Cognitive Assessment (MoCA) score from baseline to 90 days. Secondary outcomes include changes in white matter hyperintensity burden and diffusion tensor imaging metrics on MRI, EEG functional connectivity, and activities of daily living.
Detailed Description:
Cerebral small vessel disease (CSVD) is a leading cause of vascular cognitive impairment, characterized by white matter hyperintensities, lacunes, and microbleeds on MRI. Current treatment options for CSVD-related cognitive impairment are limited, and there is a critical need for safe, noninvasive interventions that can improve cognitive function and delay disease progression.
Remote ischemic conditioning (RIC) is a noninvasive, low-cost procedure induced by intermittent cuff inflation on a limb to produce brief episodes of ischemia and reperfusion. Experimental and clinical studies suggest that RIC can improve cerebral perfusion, protect the neurovascular unit, and modulate inflammatory and endothelial pathways, making it a promising strategy for CSVD.
In this single-center, randomized, double-blind, sham-controlled trial, we will enroll 40 patients with CSVD-related mild cognitive impairment. Participants will be randomized to receive either RIC (cuff inflation to 200 mmHg for 5 minutes followed by 5 minutes of reperfusion, 5 cycles per session) or sham RIC (cuff inflation to 60 mmHg, 5 cycles per session). The intervention will be administered twice daily for 90 days, in addition to standard medical therapy.
Cognitive function will be assessed by the Montreal Cognitive Assessment (MoCA). MRI will be used to quantify white matter hyperintensities and diffusion tensor imaging parameters, and EEG will be used to evaluate functional connectivity. Activities of daily living and safety outcomes will also be recorded. This study will provide clinical and mechanistic evidence on whether RIC can prevent or ameliorate cognitive impairment in patients with CSVD.
