New study finds that shorter sleep duration and poorer sleep quality are associated with a greater Amyloid burden, a biomarker for Alzheimer's disease
"Our study found that among older adults, reports of shorter sleep duration and poorer sleep quality were associated with higher levels of β-Amyloid measured by PET scans of the brain," said Adam Spira, PhD, lead author of the study and an assistant professor with the Bloomberg School's Department of Mental Health. "These results could have significant public health implications as Alzheimer's disease is the most common cause of dementia, and approximately half of older adults have insomnia symptoms."
