Common drug reduces depression in diabetics

People living with diabetes may be able to reduce the risk of developing depression and other mood disorders by including a common medication in the management of their condition. The major 12-year study based on a Taiwanese adult population cohort has shown the onset of diabetes increases the risk of mood disorders, mainly depression, by more than two and a half times. However the study, by researchers from Monash University and the National Health Research Institutes Taiwan, also found when metformin is included in the treatment of diabetes, the incidence of mood disorders was reduced by more than 50%.

Metformin is the most commonly used medication for type 2 diabetes. Taken orally, it helps control blood sugar levels. Lead author, Emeritus Professor Mark Wahlqvist said the increasing prevalence of diabetes is revealing complications beyond the well-known ones affecting the cardiovascular system, the eyes, peripheral nerves and feet.
