Maintain a Healthy Brain

Eat salmon and other types of fish may help to maintain a healthy brain. A help could also help in the prevention of Alzheimer's or Parkinson's, as documented in a new study from the US conducted at the University of South Dakota by Dr. James Pottala, a researcher at the Health Diagnostic Laboratory Inc. of Richmond, Virginia.

The fatty acids omega-3 contained in salmon and other fish would be not only a supply of nutrients useful to the balance of the values in the blood, but according to what was published in the scientific journal Neurology, these essential fatty acids would increase the volume of the brain itself, by extending in time the memory capacity.

Thanks to the omega-3, fish like salmon are rich, the ability to keep a memory intact and to delay the degeneration of cognitive are extended for a period of between 1 and 2 years. As explained by the Dr. Pottala:

These higher levels of fatty acids can be obtained through the diet and use of supplements, and the results suggest that the effect on brain volume is the equivalent of the delay from one to two years, the normal loss of brain cells that occurs with aging.
The firm has been involved for about 8 years, more than 1,100 women are part of the Women's Health Initiative Memory Study and the mean age was 78 years. Were compared to their values in the blood of omega-3 with the volume of their brain, as detected via MRI (Magnetic Resonance imaging).
Has emerged as those who had the most monounsaturated fatty acids in the blood avvessero more chance (7,5% against the 3.4% of other) have increased the size of the brain, equivalent to 0.7% of the average. In particular was higher than the size of the hippocampus (2,7% more), an area recognized as being of great importance for the management of the memory and the atrophy is in some cases prior to the onset of the symptoms of Alzheimer's disease.

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
