Researchers found differences in daily activity patterns in people who had a build-up of the protein amyloid beta in the brain, a key feature of the disease.
A device worn on the wrist may help to detect the early warning signs of Alzheimer's disease before it leads to serious cognitive decline, a study has suggested.Around six million US adults live with Alzheimer's. Although there is no cure for the progressive disease, early and accurate diagnosis allows people to access treatments for their symptoms, as well as adequate support and care.Watch-like devices called actigraphs monitor the daily activity patterns of their wearers.
'We need to replicate these findings in larger studies, but it is interesting that we've now seen a similar difference between amyloid-positive and amyloid-negative older adults in two independent studies,' said Adam Spira, a study author and professor in the department of Mental Health at the Bloomberg School, in a press release.It's not known exactly why amyloid build-up would lead to different activity patterns at specific times of day.
