Prior research has identified a trend between people who suffer from major depressive disorder and an increased onset risk of heart disease, diabetes, obesity, and cancer – and now a new study provides evidence for a molecular link that potentially helps explain why.
The researchers took blood samples from more than 2,000 volunteers: one-third of whom had been suffering from major depression at the time, another third who had suffered depressive episodes in the past, and a final third who were never depressed and served as controls. What they discovered is that, among both subjects who were currently depressed and those who had experienced depression in the past, there were signs of accelerated cellular aging in the form of shorter telomeres (with those who had more severe depression and longer duration symptoms having the shortest telomeres) – which would be a logical explanation for why they would be at increased risk for age-related diseases (though a causative link has yet to be established).
