Salt link to dementia

Too much salt could be bad for your brain as well as your heart, doctors have warned.

Elderly people who have salt-rich diets and do little exercise suffer a quicker mental decline than those who are more prudent with their intake, a study has found. Worryingly, just over a teaspoon of salt a day could dull the mind and raise the risk of Alzheimer’s, the study suggests. Salt’s danger to the heart is well known but the latest study is the first to link it to deterioration of brain health in the elderly.

The Canadian team tracked the salt consumption and levels of physical activity of 1,262 healthy men and women aged between 67 and 84 over a three-year period. They also assessed the mental health of the participants at the start of the study and once a year for the duration, using a battery of tests more commonly used to diagnose Alzheimer’s.

‘The results of our study showed that a diet high in sodium, combined with little exercise, was especially detrimental to the cognitive performance of older adults,’ said Dr Alexandra Fiocco from the University of Toronto.
