Contrast the lifestyles of people in their seventies who do and do not suffer from Alzheimer’s disease and clues about how to keep your brain ticking over nicely, well into old age, jump right out at you. Those who do not suffer with this dreaded disease tend to have been more committed to a regular exercise regime throughout their later years. They tend to have been more engaged in a wider array of social activities. They tend to have been careful with their diet in the long term, favouring a healthy Meditteranean-style diet over a typical modern Western diet. They also tend to have been more proactively involved with their local community and more motivated to seek regular mental stimulation. People are now being advised to adopt a variety of brain-healthy habits if they wish to reduce the likelihood of developing cognitive deficits that the progression of Alzheimer’s disease can, but does not always, induce.
