A recent study suggests that common diabetes drugs such as GLP-1 receptor agonists and SGLT2 inhibitors may protect against Alzheimer's disease and related dementias.
The research, conducted at the University of Florida, looked at Medicare data from older adults with Type 2 diabetes.
GLP-1RAs and SGLT2is were associated with significantly fewer cases of dementia, indicating potential brain health benefits even for non-diabetic individuals.
The study compared health outcomes of over 90,000 patients, showing lower risks of Alzheimer's and dementia in GLP-1RA and SGLT2i users.
Both drug classes were found to have neuroprotective effects beyond regulating blood sugar levels, potentially reducing inflammation and improving circulation.
Funding for the study came from the National Institute on Aging and the National Institute of Diabetes and Digestive and Kidney Diseases.
While the study was observational, the results suggest a promising link between these diabetes medications and reduced dementia risk.
Future research will explore the effects of these drugs on broader populations and their potential for preventing cognitive decline.
These findings could have significant implications for patients, caregivers, and public health as the use of GLP-1RAs and SGLT2is continues to expand.
Understanding the real-world benefits and risks of these drugs across populations will be key for future healthcare decisions.
