According to a study analysing nearly 1.7 million patients’ records, Semaglutide is Ozempic and Wegovy, which has a higher diabetes medication, which may significantly reduce the risk of dementia in patients with type 2 diabetes.
The study found that diabetic patients taking semi-guape had a significantly lower development rate than those who used other diabetes medications.
The discovery, published in the Journal of Alzheimer’s Disease, offers hope for preventing diseases that affect more than 6 million Americans, killing more than 100,000 people each year. Since dementia is currently incurable, these results may point to strong prevention strategies for people at high risk.
A sharp risk reduction was observed
Researchers at the Case Western Reserve School of Medicine used a complex statistical method that mimics randomized clinical trials to analyze three-year electronic health records. They compared Semaglutide users with patients taking seven different diabetes medications, including other drugs in the same GLP-1 receptor agonist class.
Protective effects depend on the comparison of the drugs, but all showed obvious benefits:
- Compared with insulin users, the risk is 46% lower (hazard ratio 0.54)
- Compared with metformin users, the risk is 33% lower (hazard ratio 0.67)
- Compared with older GLP-1 receptor agonists, the risk is 20% lower (hazard ratio 0.80)
- The Strongest Protection Effects Observed in Women and Elderly
- Especially effective for vascular dementia
A research team led by Xu XU, professor of biomedical informatics, uses propensity score matching to illustrate differences among patient populations. This approach helps ensure that the observed benefits come from the medication, not other patient characteristics.
Beyond blood sugar control
Halflubin is a drug called GLP-1 receptor agonists that work by mimicking hormones that regulate blood sugar and appetite. Originally developed for diabetes management, these drugs show an increasingly broad range of health benefits, including cardiovascular protection and severe weight loss effects.
The potential brain protective effects of drugs may work through multiple pathways. Type 2 diabetes itself increases the risk of dementia through various mechanisms, including chronic inflammation, vascular damage, and insulin resistance in the brain. Semaglutide addresses several of these risk factors simultaneously.
“There are no curative or effective treatments for dementia therapy, so this new study provides realistic evidence for preventing or slowing down the potential impact of dementia development in the highest risk population,” XU explained.
Specific types of dementia show different responses
This study reveals important differences in how halterotrite affects different types of dementia. Vascular dementia is caused by a decrease in blood flow to the brain and responds to treatment the most. This is biologically significant given Semaglutide’s known cardiovascular benefits.
However, the drug has no significant association with frontotemporal dementia or Lewy body dementia, suggesting that its protective mechanism may be specific to certain pathological processes rather than providing universal brain protection.
The way forward
Despite the encouraging results, the researchers stress that the limitations of observational research prevent strong causal conclusions. The obvious benefits may reflect differences between patient populations or other confounding factors.
“Our results suggest that further research on the study of Semaglutide’s dementia prevention for the prevention of dementia through randomized clinical trials,” XU noted.
This study adds to growing evidence that nearly half of cases of dementia can be prevented by addressing modifyable risk factors. As the global burden of dementia continues to increase with the aging of the population, effective prevention strategies are increasingly being identified for public health.
