Ageing test could highlight patients at risk of dementia

Technique developed by comparing gene activity from healthy 65-year-olds with youngsters could also be used for other age-related conditions

A test that can track how well a person is ageing could help doctors identify patients who are most at risk of dementia and other age-related conditions.

Those picked out as ageing fast could be referred onto clinical trials for treatments that try to prevent neurodegenerative diseases or slow the ageing process itself.
