Not Want senile? Expand is the Sun in the Morning Day
Seniors with low vitamin D levels have the potential of problems with memory, learning, and thinking. Furthermore, low vitamin D will provide early warning for risk of dementia aka senility.
Just so you know, most vitamin D is naturally produced by the body from the additional sun exposure to skin. So, bask in the morning is very beneficial in this regard.
The researchers from the UK, Italy and the United States examined 850 Italian men aged 65 years and over and find someone who is an acute shortage of vitamin D as much as 60 percent experienced a general decline in cognitive abilities. The rest, 31 percent experienced problems with mental flexibility. "This is the first study to identify a clear link between low vitamin D levels and a decrease in cognitive abilities," said study chairman, David Llewellyn from the Peninsula Medical School at the University of Exeter, UK.
Llewellyn said the findings raise concerns because of the previous depth has been estimated one billion people worldwide lack of vitamin D. He said that giving vitamin D supplements in the elderly can be a very promising therapeutic target for prevention of dementia, particularly because supplements cheap, safe and has been shown to help to reduce the risk of fractures.
Most vitamin D is naturally produced by the body from the additional sun exposure to skin. Vitamin D is also found in some foods such as fish oil and essential for our health, because it helps cells absorb calcium, essential for bone.
Some recent research has also shown vitamin D may protect against cancer, artery disease and tuberculosis.
In this study, the researchers found seniors who Llewellyn acute deficiency of vitamin D - which is defined by having 25 hidrovitamin D blood level is lower than the 25 nanomole per liter - 60 percent more likely to experience cognitive decline in the ability of these six years of research.
The results also showed 31 percent more likely to experience a decline in executive function tests to test.
These findings were also published in the journal "Archives of Internal Medicine."
Dementia is a condition that a waste of brain power that affected 35 million people in the world. The most common form is Alzheimer's disease, a disease sufferers gradually lose their memories, ability to navigate and understand the world around him and taking care of themselves.
Tim Llewellyn researchers say they think vitamin D can prevent the degeneration of brain tissue that have a role in shaping the neural network, maintaining levels of calcium in the body, or remove beta-amyloid, a substance that forms the brain plaques associated with Alzheimer's disease.
The researchers estimate that in the U.S. and Europe, between 40 to 100 percent of the elderly and vitamin D deficiency a problem exacerbated by the conditions of older people spend more time indoors and their skin becomes less efficient to produce vitamin D.
