Editor's note
|
|
By the time a person reaches 70, the pathological changes in their brain aren’t much different from people with Alzheimer’s disease – but not everyone suffers debilitating memory loss in their later years. It comes down to something called ‘cognitive reserve’, which is how resilient your brain is against disease despite biological changes.
Michael Ridding writes we can build our cognitive reserve by challenging our brains and keeping active.
