Baltimore: A simple saliva test could reveal the risk of dementia in otherwise healthy pensioners, say researchers.

The test would look for the stress hormone cortisol, which has been linked to brain function. Those with high levels would be offered screening for dementia.

A US study found that elderly people with raised cortisol levels were more likely to have a smaller total brain volume and to perform worse in thinking and memory tests.
