A new study published in the journal Neurology found that in participants without dementia, low vitamin D levels increased the risk of developing Alzheimer’s disease and other forms of dementia.

Dementia is the general term for cognitive decline that is severe enough to interfere with one’s daily life by altering memory, thinking, and behavior. Alzheimer’s disease (AD) is the most common form of dementia with more than five million Americans diagnosed with AD.

    The big surprise of this study was that they found only a 2X increase with low vitamin D.
    I cannot findl any previous study which found less than an a 2.4X increase,
    Most studies have found between 5X and 19X increase

    I think study, like many is self limiting in its conclusions.
    Comparing people with a level less than 20ng/ml with those over 20ng/ml builds in a limited comparison. If we knew the levels of the comparison cohort then we might be able to deduce the validity of the comparison. If they divided the group into 4. 40 we might see a better relationship. From their study I cannot see how the cut-off is 20 ng/ml. Its another study bent on proving the IOM optimal level.

    Hmm. Error with my post there:
    “If they divided the group into 4. 40 we might see a better relationship” should have said:

    “If they divided the group into 4: 40 we might see a better relationship”

    I have no idea what is going on with the text on these posts. The system is eliminating much of my text here???? I will re-word it again:

    “If they divided the group into 4: less than 20; from 21 to 30; from 31 to 40 and greater than 40 we might see a better relationship”

    OK, it does not accept the less than and the greater than symbols, all text between the symbols is eradicated. Strange!

    I wonder what studies would show if levels were raised optimal, as can be determined by our current hunter/gatherer societies: 40 ng/m to 80 ng/ml?

    If those folks who still live as nature intended for us to live have these vitamin D blood levels, why would it be healthy for us who live in the concrete jungle to have a lesser level (or using the symbol: < ) than 40 ng/ml?
