This was said by a group of researchers from the Johns Hopkins Bloomberg School of Public Health.
The relationship between neurodegeneration and motor activity is well known. What’s more, over the past few years, researchers have discovered that they can accurately diagnose Alzheimer’s simply by watching a patient’s gait.
The new study analyzed data from 585 people. The researchers found that from 6 pm to 6 pm, subjects with cognitive impairment moved significantly less than healthy people. In the afternoon the movement in the disabled group was also fragmented, that is, the activity was divided into noticeably short bursts.
This reduction in afternoon activity is reminiscent of a well-known Alzheimer’s phenomenon called “sunset,” said lead author of the study, Amal Vanigatunga.
“It was interesting to see this difference in the afternoon – one of the main symptoms of Alzheimer’s dementia is the ‘sunset’ phenomenon, which includes increased confusion and mood changes beginning in the afternoon, and it may be that these activity markers capture some movement associated with these symptoms,” Wanigatunga explained.
