A new study explains why chronic poor sleep is associated with cognitive decline. The scientists found that having sleepless nights or lack of sleep could augment the levels of Alzheimer’s protein amyloid beta.
The findings of the study were described in Annals of Neurology. The study was led by researchers from the Washington University School of Medicine in St. Louis.
Once the amyloid beta levels in the brain are elevated, the protein would likely start collecting into plaques. These plaques then harm the surrounding neurons and could cause brain changes that are damaging. The levels of protein rise and set off changes to the brain leading to dementia. Experts say that the brains of those with Alzheimer’s disease have these plaques.
