Scientists have discovered that abnormally prolonged sleep and drowsiness can be an important sign of Alzheimer’s because the cells in our brain that keep us awake during the day begin to die when Alzheimer’s begins.
It should be noted that persistent drowsiness can also lead to depression, but it is a timely process, as the sleepiness caused by Alzheimer’s gradually increases and is not controlled by any drug.
Experts at the “Global Brain Health Institute” conducted a detailed examination of the brains of 20 men at the University of California San Francisco. 13 of them had Alzheimer’s disease while the remaining seven did not have the disease.
After examination researchers found that Alzheimer’s disease first attacks the brain cells which are responsible to keep us awake during the day, and because of their activity, we feel refreshed at certain times of the day.
