The results are published in the scientific journal Alzheimer’s & Dementia. The researchers followed more than 1,000 men, who were initially 50 year old, between the years 1970 and 2010. The results of the study show th

In an earlier article published in the journal Sleep, Christian Benedict and colleagues showed that a single night of total sleep deprivation increased blood concentrations of brain molecules in young men that typically rise in blood upon acute brain damage.
