Work from our lab and from others has found that many of the negative aspects of cognitive ageing seen in older people appear to be linked to the amount of stress they have experienced in their life. We began by measuring the number of stressful events experienced over the lifetime. We looked at a number of factors ranging from experiencing a major illness or losing a loved one, to changing one’s social habits or moving home. Old people who have experienced a lot of stress tend to perform worse on cognitive tasks than those who experienced less stress. It’s even been found that people who move home find it more stressful because it’s not how they want it exactly, compared to those who went about designing a home and having it built to their own specification. This of course relies on resource available as well.
Research also seems to suggest that choosing the right place to live in retirement can have an impact on the aging process. It is thought that the physical, mental, and emotional benefits of staying socially engaged in your senior years are huge, and so retirement communities like The Villages in Florida are often a popular choice. It doesn’t even have to be a retirement home, there is community housing where people can interact with others from all walks of life, like unionpark.metroplaces.com, which offers places for families as well as seniors. Another way you can ensure you remain socially engaged is by making sure you have a home phone in your retirement center. This will keep you communicating with your family members, saving them from stressing over how you are. Although, if you are on the lookout for a retirement community, doing some research online can help you to narrow down a shortlist. To get you started, why not take a look at the TOTV homepage.
Crucially, old people who haven’t experienced much stress in their life perform just as well on cognitive tasks as young people. This suggests that stress has a big impact on mental ability and that the effect of this only appears in old age. Indeed, young people did not differ from each other in their performance of cognitive tests whatever their life experience of stress had been.
Not only that but the patterns of brain activity of the people taking part in our study reflect the same effect: older people (aged 60 to 80) who have experienced less stress have brain activity similar to that of younger people. However, when it comes to the brain activity of those elderly people who have led stressful lives, we find something very different going on.
