A study conducted by Evidation Health on behalf of Eli Lilly and Apple suggests that data collected from smart devices and digital apps might help speed up the diagnosis of early stages of Alzheimer’s disease.
The study, “Developing Measures of Cognitive Impairment in the Real World from Consumer-Grade Multimodal Sensor Streams,” was performed in order to assess the feasibility of using smart devices to differentiate individuals with mild cognitive impairment (MCI) and early Alzheimer’s disease (AD) dementia from healthy controls.
MCI is the clinically symptomatic, pre-dementia stage of AD; cognitive deficits do not yet impair the ability to function at work or in daily activities.
Further evidence that doing aerobic exercise can preserve brain health and function — and thereby reduce the risk of dementia — is revealed in a study of older individuals with slight but noticeable declines in memory and thinking.
The researchers — from the University of Texas Southwestern Medical Center in Dallas — think that their study is the first to use an objective measure of aerobic capacity to assess the relationship between white matter integrity, cognitive performance, and cardiorespiratory fitness in older individuals with mild cognitive impairment (MCI).
“This research,” explains first study author Kan Ding, an assistant professor of neurology and neurotherapeutics, “supports the hypothesis that improving people’s fitness may improve their brain health and slow down the aging process.”
