A new study shows that just one night of sleep deprivation increases morning blood concentrations of NSE and S-100B — molecules typically found in the brain.
Researchers from Uppsala University in Sweden say the rise in concentration of these molecules in the blood may indicate that a lack of sleep may contribute to the loss of brain tissue.
For the study, the scientists recruited 15 healthy men. In one experiment, they were sleep deprived for one night, while in the other they slept for approximately eight hours.
“We observed that a night of total sleep loss was followed by increased blood concentrations of NSE and S-100B,” said Christian Benedict, Ph.D., from the university’s Department of Neuroscience, who led the study.
“These brain molecules typically rise in blood under conditions of brain damage. Thus, our results indicate that a lack of sleep may promote neurodegenerative processes.”
“The findings of our trial indicate that a good night’s sleep may be critical for maintaining brain health,” he concluded.
The study was published in the journal SLEEP.
