Poor Sleep Tied to Rise in Alzheimer’s Protein in Blood
WebJul 13, 2024 · “Our findings indicate that age-related increases in brain inflammation have a downstream effect on Alzheimer’s disease-related tau proteins and neuronal synaptic integrity. This results in deficits in the brain’s capacity to generate fast sleep spindles, which contribute to age-related memory impairment in older adults.
