‘Self-test’ can spot first sign of Alzheimer’s

A 15-minute “selfie” test conducted at home can indicate signs of mental decline that might be the first glimmer of Alzheimer’s.

US researchers who asked more than 1,000 people aged 50 and older to take the self-administered Sage test found that 28% had cognitive impairment, a mild loss of mental functioning.

The results closely matched those from detailed diagnostic tests carried out by experts.
