This review looked at how having diabetes affects various neurological conditions, such as Alzheimer's disease, Parkinson's disease, and Multiple Sclerosis. Because the evidence comes from a narrative review of different types of studies, the findings are not yet certain enough to change standard medical practice.
Researchers found that diabetes acts as a modifier in these conditions. This means it can have different effects depending on the specific disease. In some cases, it may increase the risk of a condition, while in others, it might appear to delay the start or change how the disease progresses. It also appears to influence how patients respond to treatments.
Because of these links, there is interest in using certain diabetes medications like metformin, GLP-1 receptor agonists, and SGLT2 inhibitors for neurological benefits. However, because this review summarizes diverse evidence, more research is needed to confirm these effects. Patients should speak with their doctors about how these findings might relate to their specific health needs.
