A new study from the Karolinska Institutet in Sweden has found that a common type of diabetes medicine might also help protect against dementia. The study was published in the medical journal eClinicalMedicine and could have important effects on how doctors treat older people with type 2 diabetes.
Type 2 diabetes is a very common disease where the body has trouble managing blood sugar levels. It usually happens in adults and becomes more likely as people get older. It is already known that having type 2 diabetes can increase the risk of dementia.
Dementia is a condition where memory and thinking skills slowly get worse over time, making it harder for people to manage everyday activities.
Because of this connection, researchers have been asking an important question: could some diabetes medicines also help protect the brain?
In this study, scientists focused on a group of drugs called GLP-1 agonists. These medications are already used to help control blood sugar levels, support weight loss, and protect heart health. Now, there is evidence that they might also reduce the risk of dementia.
The researchers followed more than 88,000 older adults with type 2 diabetes for up to ten years. They used a special research method called target trial emulation, which is designed to copy the setup of a clinical trial as closely as possible. This method gives strong information about how treatments work over time.
In the study, they looked at three types of diabetes medications: GLP-1 agonists, DPP-4 inhibitors, and sulfonylureas. They wanted to see if any of these drugs were linked to a lower risk of developing dementia.
The results were very interesting. People who used GLP-1 agonists had a 30% lower risk of developing dementia compared to those who used sulfonylureas. When compared to those using DPP-4 inhibitors, the risk was 23% lower.
Bowen Tang, a Ph.D. student involved in the research, explained that these findings could help doctors choose better treatments for older diabetes patients. If a medicine can control blood sugar and also protect the brain, it would be a big advantage for older adults who are already at risk of both diabetes complications and memory loss.
However, the researchers warned that more studies are needed before any final conclusions can be made. They said that future clinical trials, where patients are randomly assigned different treatments, are important to confirm these results. Only then can doctors be sure that GLP-1 agonists really help prevent dementia, and not just by chance.
Even though more research is needed, these findings offer hope. They suggest that it might be possible to choose diabetes treatments that not only manage blood sugar but also protect brain health at the same time.
