Metformin (a drug from diabetes) increases the risk of developing dementia

Experts still do not have a common opinion about the risks associated with taking Metformin, a drug taken by patients with diabetes. Some argue that the drug increases the risk of developing cognitive impairment (up to dementia) and motor disorders (Parkinson’s disease), others deny.

Taiwanese researchers from the Taipei Medical University, led by Dr. Yichun Quan, who contributed research findings in March 2017 at the 13th Annual International Conference on Alzheimer’s and Parkinson’s Disease in Vienna, attempted to understand this problem.

For 12 years, Asian scientists have observed 9,300 patients with diabetes in the second type, analyzing the contents of their medical records, studying medical records. One half of the participants included in the study took Metformin prescribed by the doctors, the second half acting as a control group did not take. Even with the age, degree of disease and sex observed, the risk of developing dementia and Parkinson’s disease in Metformin treated was increased by more than 1.5 times compared with those taking other drugs. And the longer the patient took this medication, and the more the dose was, the higher the probability of disease.

However, there is one limitation. Patients taking Metformin could also take other medications prescribed with diabetes in parallel, so scientists have a new task – to investigate this relationship.
