Alzheimer's disease

The little sleep may facilitate the onset of Alzheimer's disease. This is the conclusion reached by researchers at the Johns Hopkins Bloomberg School of Public Health Baltimore, according to them, sleeping in an insufficient manner would represent a greater danger that the mere decrease of the momentary reactivity and cognitive.
Little sleep would help, in particular, as reported in the journal Jama Neurology, the formation of plaques of the protein Beta-amyloid around neuronal connections. This in particular is a typical symptom of the onset of dementia.
From the data of the study shows how in a sample of 70 subjects with a mean age of 76 years of age, whose hours of sleep daily ranged from more than 8 to less than 5, the presence of these plaques was inversely proportional to the number of hours spent in sleep. As reported by Dr. Adam Thorn, the guide of the study, the PET scans (Positron Emission Tomography) of the brain of volunteers has emerged as:

The number of plaques increased in a manner proportional to the hours of sleep lost. We cannot say that there is a cause-effect relationship between the lack of sleep and disease and our discovery is to deepen, but the difficulty to sleep at an advanced age, should not be underestimated. The use of therapies that facilitate sleep may help prevent or reduce the signs of dementia.
Possible negative effects from the lack of hours of sleep that we found in a study published just a few days ago, and according to which sleep helps the brain to remove the accumulated toxins. Positive effects are also recognized in maintain the health of the heart and resisting the consumption of junk food
