Brain Shrinkage begins at 40
➡️Yes, this is true. Brain volume and weight reduce in old age- this is well known. However, the fact that this process starts at 40 (or even 30 as per a few studies) is not so well-known.
➡️Volume of the brain and/or its weight declines with age at a rate of around 5% per decade after age 40 with the actual rate of decline possibly increasing with age particularly over age 70.
✅Engaging in regular physical activity, optimum sleep, engaging in cognitively-stimulating activities, consuming healthy food, and minimizing stress are some of the strategies that can slow down the process of brain ageing. more
