Anxiety is also one of the first signs of Alzheimer’s disease.
If a person often feels sleepy in the daytime, it raised the risk of Alzheimer’s disease, officials say the University of Washington.
A study was conducted involving 189 people. The experts recorded the activity of volunteers within two weeks.
Also used MRI to scan the brain. It turned out, the people with deposits of beta-amyloid protein in the brain (characteristic of Alzheimer’s disease) disturbances in brain functioning, reduced quality of sleep at night and increased daytime sleepiness. In General, it is in the early stages of Alzheimer’s people are often active at night and passive or sleepy during the day.
The trouble is, by the way, is also one of the first signs of Alzheimer’s disease. Experts at Brigham Women’s hospital analyzed data from nearly 300 elderly people. Scientists have discovered a close relationship between anxiety and protein accumulate in the brain in dementia. Patients early enough to begin to change character and mood.
The researchers compared the severity of 30 symptoms of depression in participants with the scan data of the brain. The scientists monitored the changes for almost 5 years. Experts have established that the accumulation of deposits of toxic protein in the brains of volunteers increased the level of anxiety. The researchers came to the conclusion that anxiety may be the first sign of dementia.
