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

About Alzheimer's

The hypothesis comes from the University of Florida's McKnight Brain Institute Center for Smell and Taste, and seems to show already the first positive results in the research of one of the most important diseases of cognitive degenerative diseases.
Alzheimer's is a disease that shows up in the early stages symptoms similar to that of the normal senile dementia, making it difficult identifying her quickly. Thanks to a jar of peanut butter and a metre, the researchers provide to be able to develop an effective tool to detect the disease in an economical way and already during the first stages of progress, when the symptoms are still poor or almost absent.
The central node of the test, the olfactory system, where the nerve lies in the frontal region of the skull and that seems to be one of the first to be affected by the disease. Here comes the peanut butter, a small amount is placed in a jar and approached in a progressive manner to the subject, measuring with the meter the distance from the nose.
Eyes closed and one of the two nostrils plugged during the test. The procedure is repeated two times, once for each nostril, with an interval of 90 seconds. Most of the 90 subjects involved in the experiment, divided between subjects with forms of moderate degeneration, cognitive, Alzheimer, dementia, and healthy volunteers.

All the 18 patients with Alzheimer's disease have shown that there is an important disparity in the response and in the nose of the two nostrils, the left has shown the need for a greater closeness of the jar containing peanut butter for the detection of odor, an average of 10 centimeters.
The same data is not also been found in healthy subjects, who have not reported significant differences between the two nostrils, while subjects suffering from other forms of cognitive deficits have shown poor disparities even if in favour of the right nostril.
As stated in the Dr. ssa Jennifer Stamp, who conducted the research, it is a process that needs a tune-up before you can become a fully reliable and secure. An eventuality that, however, is not excluded, but rather will be in-depth with further evidence:
At the moment we can use this test only for the confirmation of the diagnosis, but we have as its objective the study of patients with moderate disparities in cognitive for vederificare if this test can be used to discover which patients will manifest Alzheimer's disease.

The Chronic Diseases

Prevent chronic disease thanks to the Mediterranean Diet. To affirm the importance of eating well, Italian in this case are not the representatives of the local supply is correct, but rather a group of eleven experienced british, who, in a letter sent to Prime Minister David Cameron urge him to impose a change in the food policy of the United Kingdom to counter the increase in cases of dementia.
The importance of the Mediterranean Diet against chronic diseases like Alzheimer's and dementia are now more evident according to what was stated by Dr. Richard Hoffman and Dr. Aseem Malhotra, two of the authors of the study. To provide the benefits hoped for the presence in large quantities of fruits and vegetables, dried fruit and olive oil, as well as the reduced consumption of meat (1 time per week) and fish meat (at least 2 times a week).

Some of the chronic diseases that can be counteracted effectively by the use of the Mediterranean Diet are diabetes, hypertension, Alzheimer's disease and other types of cardiovascular disease. Important in the past few months has proved to be also in the phase of recovery after having a heart attack.

A natural diet and healthy as the Mediterranean Diet constitutes an important tool in the prevention of diseases such as dementia, she said finally, the same Dr. Hoffman:
The Mediterranean Diet is possibly the most effective way of helping to prevent the onset of dementia.
