As with other diseases, early diagnosis is important here.
Medical studies conducted in the US found that a violation of deep sleep may be the first symptom of Alzheimer’s disease.
A group of scientists from Washington had experience, inviting about 120 people aged from 60 years. Some of them complained of weakness and deterioration of mental abilities. Sleep quality was assessed EEG sensors. They were fixed on the wrist and foreheads of the subjects. Also recorded data about feelings in the dream day and night. After 27 volunteers agreed to donate cerebrospinal fluid analysis and PET scan.
The results showed that high levels of the protein Tau coincided with a reduction in deep sleep phase. People with a predisposition to the accumulation of this substance have been sleeping well both day and night. But the quality of their sleep was not good.
In the future we plan to conduct a number of studies, if data are confirmed, Alzheimer’s disease can be diagnosed in the early stages with the help of sleep study patients.
Recall that while this disease is incurable but there are experimental drugs that help to slow the progression of Alzheimer’s disease.
