A new study from scientists at Ohio State University has found that a 15-minute 'selfie' test conducted at home can indicate early signs of mental decline.
This might be the first indication of Alzheimer's disease.
The team hope that the test, which can be taken at home by patients, will help give doctors a 'baseline' of mental function so that progressive changes can be tracked over time with the results shared with physicians to help them spot early symptoms of dementia.
Asking more than 1,000 people aged 50 and older to take the self-administered Sage test, the researchers found that 28% had cognitive impairment, a mild loss of mental functioning.
Alzheimer's Society comment:
'This is an interesting development, but currently home tests are not a reliable way of diagnosing Alzheimer's disease, or other forms of dementia. Dementia and Mild Cognitive Impairment are difficult to diagnose, and we need to continue to fund more research into tests like this and other ways that may help improve the accuracy and ease of diagnosis.
With less than half of people with dementia getting a formal diagnosis we need to do all we can to improve this to ensure that people get the treatments and support they deserve. If you are worried about your own or a loved one's memory you should visit your GP.'
