Sleep deprivation link to Alzheimer’s protein
Researchers in the US have found a link between a single night of sleep deprivation and increased levels of amyloid protein in brain regions implicated in Alzheimer’s disease. The study, published today in the journal PNAS, adds to existing evidence pointing to a link between poor quality sleep and Alzheimer’s brain changes.
The study involved 20 volunteers between 22 and 72 years old, who received PET brain scans that measure amyloid build-up in the brain. Researchers compared levels of brain amyloid after a night of restful sleep and after a night of sleep deprivation. Sleep deprivation was associated with increased amyloid accumulation in areas of the brain associated with the early stages of Alzheimer’s disease. Alzheimer’s Research UK
