A debate has erupted within the Spanish medical community following the publication of new data on how modern treatments for type 2 diabetes affect the risk of developing epilepsy. A team of researchers from a university hospital in Madrid conducted a large-scale analysis, covering nearly half a million adult patients monitored between 2015 and 2023. The specialists focused on comparing two popular classes of medications: glucagon-like peptide-1 (GLP-1) agonists and dipeptidyl peptidase-4 inhibitors, known as gliptins.
During the study, scientists carefully matched patient data to eliminate the impact of random factors. They used a method called pseudo-randomization, which allows for highly accurate pairing of patients with identical baseline characteristics. This approach enabled the researchers to draw conclusions that have already sparked interest among endocrinologists across the country.
Research methodology
The study included men and women over 18 years old, with an average age just over 60. Half of the participants began taking GLP-1 agonists, while the other half received gliptins. All patients were monitored over several years, which allowed for an assessment of the long-term effects of the therapy.
Modern statistical methods, particularly Cox proportional hazards models, were used for data analysis. This approach made it possible to identify differences in the incidence of epilepsy between the two groups. The results turned out to be unexpected even for the authors themselves.
Results and Conclusions
According to the data, patients who took GLP-1 agonists had a noticeably lower risk of developing epilepsy compared to those who received gliptins. This effect persisted even after adjusting for factors such as age, sex, comorbidities, and duration of diabetes. The researchers emphasize that this is a statistically significant reduction in risk, which could have important implications for clinical practice.
The authors note that the exact mechanisms behind this effect remain not fully understood. However, the results may already influence the choice of therapy for patients with type 2 diabetes, especially for those with additional risk factors for neurological diseases.
Reaction of the Medical Community
The publication sparked widespread discussion among Spanish doctors and diabetes specialists. Many experts believe that the new findings open up prospects for further research into the neuroprotective properties of GLP-1 agonists. Some specialists are already discussing the possibility of revising existing clinical guidelines.
At the same time, some experts urge caution, noting that further research is needed to confirm the findings. In particular, it is necessary to determine how applicable this data is to patients with different forms of diabetes and varying levels of epilepsy risk.
Impact on patients
For Spanish patients with type 2 diabetes, the new findings may be a reason to discuss possible changes in therapy with their doctor. This is especially relevant for those who have already experienced neurological complications or are predisposed to them. Doctors advise against self-medicating or changing medications without consulting a specialist.
Additional data is expected to be published soon, which will help clarify exactly how GLP-1 agonists affect the nervous system. For now, the study remains one of the most talked-about topics in the Spanish medical press.
