The 21-question test was developed by the Banner Sun Health Research Institute in Arizona, which specialises in the Alzheimer's, to try and distinguish between normal forgetfulness and the more worrying memory lapses that could signal the early stages of dementia.
Doctors who have developed the test say it is almost 90 per cent accurate, but stress that a diagnosis is up to a GP.
The questions are answered with a simple 'yes' or 'no'. A 'yes' is given a score of one or two and a 'no' always scores zero, giving a maximum possible score of 27.
