Type 2 diabetes is a major risk factor for PSCI, and stroke patients with type 2 diabetes have a higher risk of developing PSCI. Despite the high incidence and severe impact of PSCI, effective intervention methods are still lacking. Identifying safe and effective drugs to improve cognitive function in stroke patients and reduce the risk of PSCI, especially for those with type 2 diabetes, is of significant importance and could help reduce the burden of stroke.\n\nDipeptidyl peptidase-4 (DPP4) inhibitors are first-line antidiabetic drugs, and several studies have shown that DPP4 inhibitors provide benefits beyond glucose control, including significantly improving cognitive function in patients with type 2 diabetes or slowing the progression of cognitive impairment. Our previous research found a significant negative correlation between baseline plasma soluble DPP4 (sDPP4) levels and the 90-day PSCI risk in ischemic stroke patients. Moreover, some studies indicate that DPP4 inhibitors can increase plasma sDPP4 levels. Based on this, we hypothesize that DPP4 inhibitors could be effective for PSCI intervention and may improve cognitive function post-stroke.\n\nThis project aims to conduct a multicenter, randomized, double-blind, placebo-controlled study. We will include patients with mild ischemic stroke combined with type 2 diabetes and provide continuous intervention with DPP4 inhibitors or a placebo for 180 days. Cognitive function in both groups will be assessed before and after intervention to determine if DPP4 inhibitors can improve cognitive function and reduce the risk of PSCI in ischemic stroke patients with type 2 diabetes. Clinical blood samples and imaging data will also be used to preliminarily explore potential mechanisms.",[83,84],"Ischemic Stroke","Diabete Mellitus",[86,83,87,88,89],"DPP4 inhibitors","PSCI","Diabetes Mellitus","RCT","NOT_YET_RECRUITING","2025-11-18",{"date":93,"type":94},"2025-11-21","ACTUAL",{"date":96,"type":77},"2025-12-15",{"date":98,"type":77},"2028-04-30",{"name":5,"class":6},1]
