This will be the 1st in a series of Blogs on Alzheimer's Disease. This has been a medical interest of mine since 1990.
If you ever wondered by Alzheimer has an apostrophe, it is because the disease is named for a German physician, Alois Alzheimer
( https://www.alz.co.uk/alois-alzheimer ) whose clinical work in the 1st decade of the 20th century identified an 'unusual disease of the cerebral cortex'.
The work in this recent article:
A Systematic Review and Meta-analysis of The Effect of Low Vitamin D on Cognition
J Am Geriatr Soc. 2017;65(10):2161-2168.
concluded: "Observational evidence demonstrates low vitamin D is related to poorer cognition; however, interventional studies are yet to show a clear benefit from vitamin D supplementation. …… lifespan studies are necessary to depict the optimal timing and duration in which repletion of vitamin D may protect against cognitive decline and dementia in aging, …..”
This is of particular interest because of the now recently confirmed errors made in the calculation of recommended daily amount (RDA) for Vitamin D.
Happy to discuss this.
