Active brain 'keeps dementia at bay'

[Northerner]

Keeping mentally active by reading books or writing letters helps protect the brain in old age, a study suggests.

A lifetime of mental challenges leads to slower cognitive decline after factoring out dementia's impact on the brain, US researchers say.

The study, published in Neurology, adds weight to the idea that dementia onset can be delayed by lifestyle factors.

An Alzheimer's charity said the best way to lower dementia risk was to eat a balanced diet, exercise and stay slim.

There was a study about 15 years ago looking at the relationship between education and dementia. It concluded that the symptoms of Alzheimers did not become detectable until it had progressed much further in people who were educated to higher level. I wonder if that effect is being demonstrated here.
