D-vitamiini ja ikäihmisten aivot - 0 views

  •  
    "D-vitamiinin puute on yleistä ikääntyvillä ihmisillä ja se heikentää aivotoimintaa, osoittaa uusi tutkimus. Suosittelen ikääntyville D-vitamiinia päivittäin niin paljon, että seerumin D-vitamiinin pitoisuus (25-OHD) ylittää 75 nmol/l. Yleensä siihen tarvitaan vähintään 50- 75 mikrogrammaa D-vitamiinia päivässä.
    Bostonissa vuosina 2003-2007 tehtyyn tutkimukseen osallistui 318 kotipalvelun piirissä olevaa henkilöä, iältään 65-99 vuotta (keski-ikä 73 vuotta). Heistä 231 (72,6 %) oli naisia. Kaikista mitattiin seerumin D-vitamiinin pitoisuus (25-OHD). Hyvin matalia pitoisuuksia (alle 25 nmol/l) oli 14,5 prosentill"

Vitamin D and Memory - Amen Clinics - 0 views

    "One of the surprises over the past year has been all the research regarding Vitamin D and brain health. Give that many people are spending less time outdoors and more time in front of their computers, we all should be concerned, as Vitamin D comes in part from our exposure to the sun.

    Low Vitamin D levels have been associated with pain, depression, MS, cancer and now perhaps even dementia. Here are the results of a new study that should cause all of us to pay attention. I frequently check the Vitamin D levels in my patients and frrequently see that they are below the optimal level. Get your levels checked if you have any of these concerns.

    A new large-scale senior population study has found that a lack of vitamin D in the elderly could be linked to cognitive impairment.

    The study, conducted on almost 2,000 adults over the age of 65, is the first of its scale to identify this relationship, and prompted researchers to suggest vitamin D supplementation as a possible means of reducing the risk of dementia. "

Is vitamin D deficiency linked to Alzheimer's disease and vascular dementia? - 0 views

  •  
    Amsterdam, The Netherlands, May 26, 2009 - There are several risk factors for the development of Alzheimer's disease and vascular dementia. Based on an increasing number of studies linking these risk factors with Vitamin D deficiency, an article in the current issue of the Journal of Alzheimer's Disease (May 2009) by William B. Grant, PhD of the Sunlight, Nutrition, and Health Research Center (SUNARC) suggests that further investigation of possible direct or indirect linkages between Vitamin D and these dementias is needed.

    Low serum levels of 25-hydroxyvitamin D [25(OH)D] have been associated with increased risk for cardiovascular diseases, diabetes mellitus, depression, dental caries, osteoporosis, and periodontal disease, all of which are either considered risk factors for dementia or have preceded incidence of dementia. In 2008, a number of studies reported that those with higher serum 25(OH)D levels had greatly reduced risk of incidence or death from cardiovascular diseases
