In order to slow down cerebral aging, and to reduce the risk of progression to cognitive impairment (or even dementia), it is important to make your brain “work”. These experts focused its attention on mild cognitive impairment. This is characterized by difficulties in accomplishing certain daily tasks, without however affecting autonomy. We are somewhere between “normal” cognitive decline, linked to advancing age, and dementia, which is obviously much more severe.
For the Researchers
The researchers analyzed data on some 2,000 seniors and elderly, followed for several years. A questionnaire made it possible to determine the type of mental activities practiced between 50 and 65 years, and for some from 66 to 78 years. This information was crossed with cases of mild cognitive impairment (which we know can constitute, but it is not systematic, a step towards dementia). What do we see?
- Using a computer in middle age is associated with a 48% reduced risk of developing mild cognitive impairment, and a 30% decrease when used at an older age.
- Participation in social activities (middle or older age) reduces the risk by 20%.
- Ditto for the practice of mental games (crosswords, sudoku).
- Manual activities(DIY, gardening) reduce the risk by 42%, knowing that this benefit is observed in the event of long-standing practice, and in the most advanced age group.
The effect is cumulative: the more diligently a person engages in different activities, the more they benefit cognitively. The authors comment, “We don’t have drugs that can effectively treat mild cognitive impairment, or dementia. In this context, there is a sustained interest in the factors of lifestyle, inexpensive and accessible to all, which can contribute to slowing down the aging of the brain, and the development of the problems of reflection and memory”.

Loss of visual acuity, weight gain, insulin resistance, cognitive decline
With age, health problems multiply. But today, researchers at the University of Washington (United States) could have got their hands on a protein that would limit the harmful effects of aging.
Spectacular results in mice
In particular, they were able to observe – in mice, therefore – a younger physical appearance, increased muscle activity, better sleep, sharper memory, improved insulin production and the functions of the photoreceptors of the cell eye and even a life prolonged by about 16%.
You don’t always have to buy expensive creams: a healthy diet rich in folate has been proven to help slow the aging process of the skin and contribute to a youthful appearance.
Our skin is exposed to environmental influences on a daily basis, causing damage and destroying existing skin cells. Therefore, these must be replaced regularly, which is done by rapid and frequent division of skin cells. About every 28 days, the top layer of the skin renews itself completely. This cell renewal process slows down with age, however, and the skin wrinkles and loses its firmness and elasticity.
