Sleepiness: just tiredness or an alarming symptom?

Constant sleepiness during the daytime is not just a manifestation of fatigue and exhaustion of the body, but also an alarming sign that may indicate the approach of a serious neurological disease. Scientists from the University of Washington believe that people who are often drowsy have an increased risk of developing Alzheimer’s disease.

American experts conducted an experiment with the participation of 189 volunteers, who were observed and recorded their activity for 14 days. The dynamics of the central nervous system of the study participants was recorded using MRI. It turned out that people who have a marker of Alzheimer’s disease – deposition of beta-amyloid protein in the brain, regularly face disturbances in its normal functioning, a decrease in the quality of night sleep and daytime sleepiness. Scientists noted that at the initial stage of the disease, people are often active at night and behave rather passively during the day.

Experts have called increased anxiety as another manifestation of the early stage of Alzheimer’s disease.
