Out of the 4 groups, lone the full slumber deprivation radical was recovered to consistently person an accrued encephalon property of 1 to 2 years aft a azygous nighttime of slumber deprivation. Brain property wasn't importantly changed successful the different groups. Additionally, a afloat night's sleep reverses the aging effects connected the brain. 

There are limitations to this survey regarding the property of participants and the duration of the study.
