Researchers Washington University Medical School St. Louis, United StatesThe elderly, the elderly, have found the need to refresh their memories and relax, to have a higher level tau brain protein. This protein is Alzheimer's disease brain damage and cognitive deterioration.
This study, in the translation of medicine in science & # 39; As it was published on Wednesday, poor quality quality can damage a signal for the health of the brain.

"The interesting thing is to reduce the slow wave and to compare comparative relationships between tau protein, because they are common or mild to moderate, which means that this reduction may be a normal and poor transition," explained Brendan Lucey, assistant neurologist and professor at Washington University Director of Sleep Medicine Center.
He added: "As people sleep, it can be a non-invasive way of detecting Alzheimer's disease before the first symptoms."
To better understand the relationship between sleep and illness, 119 people were 60 or older. 80% were cognitively normal and the rest had a disability. With a portable EEG monitor, during one week, the dwelling participants drank.
The researchers also measured brain beta amyloid and tau protein levels and brain fluid that provide brain and spinal cord tests. After controlling the factors linked to sex, age and movement, The researchers found that slow-wave lotions are higher levels of brain levels.
The authors claim that if future research findings confirm, sleep monitoring may be the first and easiest way to detect Alzheimer's disease.

Work team Behavioral Neurology Behavior and Cognitive Neuroscience in Argentine Neurology, says Alzheimer's disease "must be detected and treated early, and patients with minimal cognitive impairment should be monitored."
Although this disease occurs Greater prevalence of over 65 year olds aged, 40 years or older, in inherited forms.
Additionally, the diagnosis of the probable Alzheimer's commitment is to "increase key variations in cognitive functions and daily changes in behavior and behavioral behavior". Among the clinical features that come with the diagnosis of the disease, there are symptoms associated Depression and insomnia.
