GLP-1 receptor agonists reduced dementia risk by 20% (HR 0.80) and Alzheimer’s disease risk by 24% (HR 0.76) versus DPP4 inhibitors in diabetic CKD patients.
Does GLP-1RA use reduce the risk of dementia and Alzheimer's disease in patients with type 2 diabetes and CKD stage 3 or later compared to DPP4 inhibitors?
In patients with type 2 diabetes and CKD stage 3 or higher, GLP-1 receptor agonists are associated with a significantly lower risk of incident dementia and Alzheimer's disease compared to DPP4 inhibitors.

Abstract Background Patients with chronic kidney disease (CKD) and type 2 diabetes mellitus (T2DM) are at increased risk of developing dementia and Alzheimer’s disease due to vascular dysfunction, insulin resistance, and chronic inflammation. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have shown neuroprotective properties; however, their impact on dementia risk in diabetic patients with CKD remains uncertain. This study evaluated the association between GLP-1RAs use and dementia risk in patients with CKD stage 3 or later, compared to dipeptidyl peptidase-4 inhibitors (DPP4is). Methods This retrospective cohort study analyzed data from the TriNetX global research network, comprising electronic medical records from 67 healthcare organizations in the US Collaborative Network. We identified patients with CKD stage 3 or later and T2DM who were newly prescribed GLP-1RAs or DPP4is between January 1, 2015, and December 31, 2020. Patients with prior GLP-1RAs or DPP4is use, a dementia diagnosis within 12 months before the index date, or recent hospitalization were excluded. The primary outcome was the incidence of dementia, Alzheimer’s disease, vascular dementia, frontotemporal dementia, Parkinson’s disease, extrapyramidal and movement disorders, and dementia with Lewy bodies, assessed over a follow-up period ranging from 90 days to 5 years. Statistical analyses included Kaplan–Meier survival curves and Cox proportional hazards models. Results GLP-1RAs use was associated with a significantly lower risk of dementia (HR: 0.80, 95% CI: 0.71–0.91, p = 0.001) and Alzheimer’s disease (HR: 0.76, 95% CI: 0.59–0.98, p = 0.033) compared to DPP4is use. However, no significant differences were observed in vascular dementia, frontotemporal dementia, Parkinson’s disease, extrapyramidal and movement disorders, or dementia with Lewy bodies. Conclusions GLP-1RAs therapy may reduce the risk of dementia and Alzheimer’s disease in patients with CKD stage 3 or later, offering potential neuroprotective benefits beyond glycemic control. Research is needed to confirm these findings and optimize treatment strategies for this vulnerable population.
