Summary:
GLP-1 agonists like Ozempic have been shown to reduce the risk of dementia in type 2 diabetes patients. A study tracking over 88,000 individuals for up to ten years found a 30% lower risk of dementia compared to sulfonylureas and a 23% lower risk compared to DPP-4 inhibitors.
These findings could help doctors choose the best medications for older diabetes patients, though further randomized trials are necessary to confirm these results.
Key Facts:
– Significant Risk Reduction: GLP-1 agonists reduce dementia risk by 30% compared to sulfonylureas.
– Study Scope: The study followed over 88,000 older adults with type 2 diabetes for up to ten years.
– Clinical Implications: These findings can help doctors make informed medication choices for diabetes patients.

New Study Links GLP-1 Agonists to Lower Dementia Risk
People with type 2 diabetes who are treated with GLP-1 agonists have a decreased risk of developing dementia, according to a new study from Karolinska Institutet published in the journal eClinicalMedicine.
GLP-1 agonists, also known as GLP-1 analogs, have gained popularity for treating type 2 diabetes and obesity due to their ability to control blood sugar, promote weight loss, and protect heart health.
The study showed that patients using GLP-1 agonists had a 30% lower risk of developing dementia compared to those using sulfonylureas, and a 23% lower risk compared to those using DPP-4 inhibitors.
Study Overview
In this register-based study, researchers followed over 88,000 older individuals with type 2 diabetes for up to ten years. Using a study design called target trial emulation, which mimics a randomized clinical trial, they analyzed the association between three diabetes drugs (GLP-1 agonists, DPP-4 inhibitors, and sulfonylureas) and the risk of dementia.
Findings
The study found that patients using GLP-1 agonists had a significantly lower risk of developing dementia compared to those using sulfonylureas and DPP-4 inhibitors.
“This is important because it can help doctors make better decisions about which medicines to use for older patients with type 2 diabetes,” said Bowen Tang, a Ph.D. student in Sara Hägg’s research group at the Department of Medical Epidemiology and Biostatistics, Karolinska Institutet. “However, proper randomized trials are needed to establish with certainty that GLP-1 agonists reduce the risk of dementia.”

Abstract
The study investigated the comparative effectiveness of GLP-1 agonists, DPP-4 inhibitors, and sulfonylureas on the risk of dementia in older individuals with type 2 diabetes in Sweden. Using data from Swedish national registers, the researchers followed participants for up to ten years. They found that GLP-1 agonist initiation was associated with a reduced risk of dementia compared to sulfonylureas and DPP-4 inhibitors.
Interpretation
The research suggests that GLP-1 agonists are associated with a lower risk of dementia in older individuals with type 2 diabetes. Further clinical trials are necessary to validate these findings.
Funding
The study was funded by the Swedish Research Council, Karolinska Institutet, the National Institute on Aging, the National Institutes of Health, and Riksbankens Jubileumsfond.
