Low Vitamin D Levels Linked To Poorer Cognitive Function In MS Patients

May 5, 2010 by  

Low vitamin D levels linked to poorer cognitive function in MS patients According to a new study presented at the American Academy of Neurology’s annual meeting earlier this month, insufficient blood levels of vitamin D may be linked to increased cognitive impairment and more advanced physical disability in patients suffering from multiple sclerosis (MS).

For the study, researchers from the University at Buffalo recruited 208 patients diagnosed with relapsing-remitting MS and 28 with the more destructive, secondary progressive form of the disease.

After analyzing each patient’s blood serum samples and their MRI scans, the research team found that only 7 percent of participants with the more serious form of MS had sufficient levels of vitamin D. In contrast, nearly 20 percent of patients with the relapsing-remitting form of the disease had adequate blood levels of the nutrient.

Furthermore, the investigators discovered a link between extremely low vitamin D levels and poor neuropsychological assessments.

"Results showed that MS patients who were impaired on tests of executive function—critical reasoning and abstract thinking—and the ability to plan and organize, were more likely to be deficient in vitamin D," said lead author Sarah Morrow.ADNFCR-1961-ID-19755055-ADNFCR

    Worrying about vitamin D toxicity is like someone dying of thirst worrying about drowning. There are multiple studies showing how common insufficient levels of vitamin D have become in our present lifestyle. Most vitamin D experts agree that up to 10,000IU per day are safe and they use 50,000 IU once per week for eight weeks to bring up levels in severely deficiency folk. Take a look at vitaminD3world It has lots of good information

      toby lee,
      my Dr. prescribed 50,000 units twice a week for me and I have been taking it now for about 4 or 5 months. Doing a lot better with it too! more energy and bounce to my step even with neuropathy in my legs!

    Wow! My brother has “MS”, and I am sending this article to him! Could make the difference for him in how he copes with the disease. Where he lives up in Northern California, it rains a lot, and he doesn’t get much sun. It has been especially rainy this winter, in fact. Almost 6 straight months of rain & storms! Normally there is maybe 3 months worth. The sun is just starting to peak out from behind the clouds up there. But where I live it is actually quite sunny most of the time, yet even here,the rains have been unusually frequent, when normally it is sun, sun, sun. If he gets enough sun, the natural vitamin D will help I am sure. But in winter he will have to take a “D” supplement. I am wondering what would be an adequate amount. Or how much sun to get per day for MS people. Possibly more than normal people?

    Susie. I was diagnosed with replapsing remitting MS in 2003. In July 2009 blood tests showed that I was severely Vitamin D defficient and I was prescribed 50,000 Units Vitamin D (gel caps) which I take weekly. I would suggest that the proper dosage for your brother be determined by blood test results & recommendation from your brother’s doctor. There is a wonderful MS support site which you can visit & participate in that is full of very good information. PatientsLikeMe
    Hope this is helpful. Kathleen

    Save America Susie, yeah, careful with the dose recomendations for your brother. Vit D can be toxic. I safely take 5,000 IUs a day and have been for years. Its true the RDA for vitamin D is way too low.

    I too have heard the Vitamin D/MS link before. Unfortunately far too many doctors are nutritionally illerterate. If I spelled illerterate wrong I am a boob…spell check doesn’t work here.

    If you cannot find a doctor that sees the value in nutrition, find a new doctor. A guy my wife works with has had his Crohns actually cured by an alternative medicine doctor, when officially there is no cure. I don’t know what was done for him, but my point is, never accept the nonsense that there is nothing they can do for you other than treat the symptoms.
    Good luck to the both of you.

    And thanks to Bob for making this most valuable information available.

    Just thought I’d pass this along…
    Bob Livingston has a private Newletter called the Bob Livingston Letter. its got a lot of cutting edge medical research and nutritional info in it. Political too.
    Thought you might be interested…

  • stuff

    Take 5000Ui daily. Why take it once weekly?

  • Save America Susie

    Thanks, Kathleen. I decided to check again to see if there was any good info added since this morning….Every little bit helps!

  • Old Grouch

    Where was all this information in 1952? I tried bee stings and
    chelation therapy a few years ago with some success. I sure would
    have jumped on Vitamin D, too, had I heard about it. It seems to
    get more and more difficult to find an Alternative Doctor.

  • Save America Susie

    Sidewinder, That is interesting to know. I had heard “D” could be toxic years ago….I had also heard that Calcium is helpful for many things including reducing pain. I have used it in the past to alleviate the pain of cramps, and it does help. Cuts some types of pain in half. Years ago in the 60′s, I read Adelle Davis books on nutrition. She clued me into the thing about Calcium and vitamin D must be taken with it for it to work right. Also Magnesium. I read that a woman needs more calcium after she enters menopause. Any hormonal event in her life she may need more. And “D” plays an important role. Interesting that it may be a “God Send” for MS as well.
    Thanks for your input as well.
