Abstract: GLP-1 agonists like Ozempic cut back the chance of dementia in kind 2 diabetes sufferers. The analysis adopted over 88,000 people for as much as ten years, displaying a 30% decrease danger in comparison with sulfonylureas and a 23% decrease danger in comparison with DPP-4 inhibitors.
These findings can information docs in deciding on drugs for older diabetes sufferers. Nevertheless, additional randomized trials are wanted to verify these outcomes.
Key Info:
- Vital Threat Discount: GLP-1 agonists cut back dementia danger by 30% in comparison with sulfonylureas.
- Research Scope: Adopted over 88,000 older adults with kind 2 diabetes for as much as ten years.
- Scientific Implications: Findings may help docs make knowledgeable remedy decisions for diabetes sufferers.

Individuals with kind 2 diabetes who’re handled with GLP-1 agonists have a decreased danger of growing dementia, based on a brand new examine from Karolinska Institutet revealed within the journal eClinicalMedicine.
Medication generally known as GLP-1 agonists or GLP-1 analogs have turn into more and more widespread in treating kind 2 diabetes and weight problems as they assist management blood sugar, promote weight reduction and shield the center.
Individuals with kind 2 diabetes have an elevated danger of growing dementia and it’s been hypothesized that newer diabetes medication equivalent to GLP-1 agonists and DPP-4 inhibitors might need a protecting impact.
Within the new register-based examine, researchers adopted greater than 88,000 older people with kind 2 diabetes for as much as ten years. Utilizing a examine design referred to as goal trial emulation, which imitates a randomized scientific trial, they analyzed the affiliation between three diabetes medication (GLP-1 agonists, DPP-4 inhibitors or sulfonylureas) and the chance of dementia.
May help docs make higher choices
They discovered that sufferers who used GLP-1 agonists had a 30% decrease danger of growing dementia in comparison with those that used sulfonylureas, and a 23% decrease danger in comparison with those that used DPP-4 inhibitors.
“That is necessary as a result of it could actually assist docs make higher choices about which medicines to make use of for older sufferers with kind 2 diabetes,” says Bowen Tang, a Ph.D. scholar in Sara Hägg’s analysis group on the Division of Medical Epidemiology and Biostatistics, Karolinska Institutet.
“Nevertheless, correct randomized trials are wanted to determine with certainty that GLP-1 agonists cut back the chance of dementia.”

“Comparative effectiveness of glucagon-like peptide-1 agonists, dipeptidyl peptidase-4 inhibitors, and sulfonylureas on the chance of dementia in older people with kind 2 diabetes in Sweden: an emulated trial examine” by Bowen Tang et al. eClinicalMedicine
Summary
Comparative effectiveness of glucagon-like peptide-1 agonists, dipeptidyl peptidase-4 inhibitors, and sulfonylureas on the chance of dementia in older people with kind 2 diabetes in Sweden: an emulated trial examine
Background
The comparative effectiveness of glucagon-like peptide-1 (GLP-1) agonists, dipeptidyl peptidase-4 (DPP-4) inhibitors, and sulfonylureas on the chance of dementia in older people with kind 2 diabetes mellitus (T2DM) is unknown.
Strategies
We carried out a sequential trial emulation from 1st January 2010 to thirtieth June 2020 utilizing knowledge from Swedish nationwide registers. Swedish residents who have been aged 65 or older, had kind 2 diabetes (T2DM), and initiated GLP-1 agonists, DPP-4 inhibitors, or sulfonylureas have been adopted for as much as 10 years to evaluate the chance of dementia. Contributors who had dementia, used the three drug lessons, or had contraindications have been excluded from enrollment.
The traits between arms have been balanced by way of the appliance of propensity scores estimated from predefined covariates. Intention-to-treat results have been analysed with all enrolled members, whereas the per-protocol results have been analysed with members who adhered to the assigned therapy.
Findings
The pooled trial included 88,381 members who acquired prescriptions for GLP-1 agonists (n = 12,351), DPP-4 inhibitors (n = 43,850), or sulfonylureas (n = 32,216) at baseline and have been adopted for a median of 4.3 years. A complete of 4607 dementia instances developed throughout follow-up: 278 for the GLP-1 agonist initiators (incidence price: 6.7 per 1000 particular person years), 1849 for DPP-4 inhibitor initiators (IR: 11.8), and 2480 for sulfonylurea initiators (IR: 13.7).
In an intention-to-treat evaluation, GLP-1 agonist initiation was related to a decreased danger of dementia in comparison with sulfonylureas (hazard ratio: 0.69, 95% CI: 0.60–0.79, p < 0.0001) and DPP-4 inhibitors (HR: 0.77, 95% CI: 0.68–0.88, p < 0.0001), after adjusting for age, enrollment 12 months, intercourse, socioeconomic components, well being circumstances, and previous remedy makes use of.
These findings have been constant in a number of sensitivity analyses, together with a per-protocol evaluation (HR for sulfonylureas: 0.41, 95% CI: 0.32–0.53, p < 0.0001; HR for DPP-4 inhibitors: 0.38, 95% CI: 0.30–0.49, p < 0.0001).
Interpretation
Our analysis advised that GLP-1 agonists have been related to a decrease danger of dementia in comparison with sulfonylureas and DPP-4 inhibitors in older people with T2DM. Additional scientific trials are wanted to validate these findings.
