Inflammation Predicts Depression and Anxiety Four Years Later in Older Americans
A large study of retired Americans found that those with high levels of the inflammatory marker C-reactive protein in the blood had more depression and anxiety. Higher CRP also predicted severity of depression and anxiety four years later.
The study, by researchers Joy E. Lin and Aoife O’Donovan, included 18,603 people over age 50 from the Health and Retirement Study. It was presented at the 2016 meeting of the Society of Biological Psychiatry.
Lin and O’Donovan hope that treating or preventing inflammation may be the key to preventing symptoms of depression and anxiety.
