Anybody who has experienced Alzheimer's will know the helplessness that comes
with this devastating disease. Anybody who has seen it in a friend or family
member will know the pain that comes from seeing your loved one deteriorate.
A powerful leader accustomed to driving multiple operations will gradually
lose command. A dedicated grandmother may forget the names of the grandchildren
she loves.
When I read one woman's story about how she came to accept that she had
Alzheimer’s, my heart broke a little. She says:
“I think there comes a point in everyone’s life when we pause to reflect on
the past, realize the present and look to the future. That happened for me at
the age of 46. I’d been married for over 20 years. Our son was in his freshman
year of college. I was happy in my job and my husband was looking forward to
retirement.
“In the fall of that year I started to become forgetful – which was not like
me at all. I had an almost photographic memory. I had a stressful job and worked
long hours, so I blamed that for my forgetfulness. I couldn’t remember things
like my home phone number, my associates’ names, or on bad days, how to get
home.
“I remember that many times I would stop at a gas station. After filling my
tank [I wouldn’t] know whether I was going to work or coming home. I tried
desperately to hide it and became pretty good at it! But one day in December, my
husband and I were out shopping. He went to a different department in the
store. The next thing I knew was that I couldn’t remember where I was or how I
got there. It was time to fess up…"Kris, from Georgia
Alzheimer’s can be a debilitating disease that can dramatically transform
your life. It’s an insidious disease that can rock your confidence and rob you
of your yesterdays. As one sufferer says, “I feel that I am robbed of any future
because while I will live in it, I will be unlikely to remember it."
It’s a brutal reality to have to accept. But scientists are offering hope in
fighting the disease. Over 4,000 scientists attended the recent
International Conference on Alzheimer's Disease. And amidst a flurry of
presentations, they reported that simple vitamin D may be your best defense
against Alzheimer’s.
"Sunshine" Vitamin Boosts Brain Function
Sounds too good to be true? Not according to a new study revealed at the
conference. The study says that vitamin D deficiency raises your risk of mental
decline by up to 394 percent.
The study is just the latest to show that the “sunshine vitamin" is essential
to good brain health. It was conducted by the Peninsula Medical School in
Exeter, England. It reviewed participants as they completed a series of tests
and exams.
Tests included memory, time and space orientation, and attention-focusing
exercises. Vitamin D levels were measured from blood samples and compared with
test performances.
"There are some fantastic findings this year," said Professor William Thies,
the chief medical and scientific officer of the Alzheimer's Association. He said
these findings "are some of the first reports of this type in Alzheimer's" and
"have the “potential to move the field forward."
Study results showed that the risk of cognitive impairment was 42 percent
higher in people deficient in vitamin D. Impairment was 394 percent higher in
those who were severely deficient in it.
"The odds of cognitive impairment increase as vitamin D levels go down," says
study author David Llewellyn. “Given that both vitamin D deficiency and dementia
are common throughout the world, this is a major public health concern."
The Peninsula Medical School also worked on an earlier related study. It too
offered evidence supporting this simple truth: seniors who get their daily dose
of "sunshine" maintain stronger cognitive functioning.
Critical research, based on tests conducted on almost 2,000 U.K. senior
citizens, showed a clear correlation between the presence of the "sunshine
vitamin" and healthy mental function.
Sunshine is an important source of vitamin D. UVB rays initiate the
production of the vitamin in human skin. Vitamin D also helps maintain strong
bones (through the absorption of calcium and phosphorus) and a healthy immune
system.
According to study author Dr. Iain Lang, the results indicate that
individuals with the lowest levels of Vitamin D were 50 percent more likely to
suffer impaired mental faculties. In other words, as vitamin D levels in seniors
decreases, mental impairment increases.
“Getting enough vitamin D can be a real problem," said Dr. Lang.
“Particularly for older people, who absorb less vitamin D from sunlight. One way
to address this might be to provide older adults with vitamin D supplements."
Older people lose their capacity to absorb Vitamin D from sunlight as the
body ages. That means they must seek other sources of the "sunshine vitamin."
Sources of “Sunshine"
According to Rebecca Wood, chief executive of the Alzheimer's Research Trust,
Vitamin D can also be found in foods such as oily fish and eggs. She adds that
these foods are key sources of vitamin B12, which studies have shown to also
help in protecting the brain.
Maggie Ward - nutrition director at The UltraWellness Center in Lennox, MA -
says the best animal source is liver, especially from cod, herring, and
sardines.
“That’s why those living in dark climates have these fish as a staple in the
diet," she says. “Nature always knows best."
“This is one of the many reasons I love summer," she says. “I get my vitamin
D from the sun and have one less supplement to take."
The Vitamin D Council offers several good tips to ensure you get just the
right amount of “sunshine." Check out these four ideas:
- Have your doctor check your
vitamin D levels. This will give you a good idea of how much vitamin D you
need to supplement.
- Make sure you’re getting
vitamin D3 in your diet. Smart options are capsules or drops. To improve
absorption, take it with food containing fat. Fat makes it more soluble.
- Have your levels rechecked
every three months. Vitamin D is a hormone, so it fluctuates for everyone.
Seasonal changes also affect it.
- People with dark skin need at
least 5 to 10 times more sunlight than light-skinned people.
"Vitamin D supplements have proven to be a safe, inexpensive, and effective
way to treat deficiency," says Llewellyn. "However, few foods contain vitamin D
and levels of supplementation in the U.S. are currently inadequate."
But you don’t have to be deficient.
