研究显示 中年压力会造成大脑萎缩
Stress in middle age can make your brain shrink and make your memory worse, scientists have discovered. The brain-reducing effects of stress were found to be triggered by cortisol. The high levels of the stress hormone may be an early warning sign someone may end up with dementia, the research suggests. Stress also made people's thinking skills worse, the Harvard Medical School study found. For the research, scientists led by Dr Justin Echouffo-Tcheugui studied 2,231 people with an average age of 49 and free of dementia. He said: "Our research detected memory loss and brain shrinkage in middle-aged people before symptoms started to show." "So it's important for people to find ways to reduce stress, such as getting enough sleep, engaging in moderate exercise, incorporating relaxation techniques into their daily lives, or asking their doctor about their cortisol levels and taking a cortisol-reducing medication if needed." |
