Keeping quiet about nagging worries often feels like the polite thing to do. However, new evidence shows that this habit may carry a hidden cost, slowly wearing down the memory centers that help us keep track of names, appointments, and the story of our lives.
Researchers followed 1,528 Chinese Americans aged 60 and older for roughly six years, asking detailed questions about how often they felt hopeless, overloaded, or personally to blame for life’s hassles.
The study was led by neurologist Michelle Chen of the Rutgers Institute for Health, Health Care Policy and Aging Research.
In Chen’s study, each standard deviation jump on that scale translated to about 0.024 standard deviations of extra memory loss per year – a pace similar to the impact of a small stroke.
In other words, people who kept feelings bottled up lost ground almost four times faster than peers who talked things out.
