Less Sleep More Brain Fog?
Researchers at the Johns Hopkins Bloomberg School of Public Health in Baltimore found that getting less sleep or sleeping poorly was tied to an increase in brain levels of beta-amyloid, a toxic protein that builds up and forms plaques in the brains of those with Alzheimer’s.
The researchers studied 70 older adults, average age 76, who were part of the ongoing Baltimore Longitudinal Study of Aging. Using brain scans, they found that those who said they got the least sleep, under five hours a night, or who slept fitfully had higher levels of beta-amyloid in the brain than those who slept over seven hours a night. The findings appeared in the journal JAMA Neurology.
