Sleepless nights raise brain levels of Alzheimer’s protein: study

After a night of no sleep, even a healthy brain has higher than normal levels of the protein that forms the signature tangles in Alzheimer’s disease, according to a new study from the Netherlands.

“We think normal healthy sleep helps reduce the amount of (amyloid) beta in the brain and if your sleep is disturbed this decrease is prevented,” said the study’s senior author Dr. Jurgen Claassen, from Radboud University Medical Center in Nijmegen.

In people who repeatedly fail to get a good night's sleep, the amyloid-beta concentration may build up and could be one factor in the development of Alzheimer’s disease, he said.
