If you’ve been diagnosed with major depressive disorder (MDD), your ageing may be accelerated by up to ten years, according to a new study. In the study, Dutch researchers compared the telomere (repetitive DNA that helps to prevent the end of chromosomes from deteriorating) length of those with current MDD, those in remission and healthy controls. They found that telomere length was significantly shorter among those with both current and remitted MDD in comparison to the healthy controls. This spells bad news for those with MDD who have shortened telomere length: this equates to four to six years of accelerated ageing. And the more severe your MDD and the longer you suffer from it, the shorter your telomere length. In the most severe cases, the telemore shortening meant 7 to 10 years of accelerated ageing.
