Here is another recent meta-analysis: http://blog.vitamindcouncil.org/2012/10/29/alzheimers-d-deficiency-association-meta-analysis-and-review-confirm/
And here is a very promising study that shows vitamin D added to Namenda treatment works better than Namenda alone. While the study was retrospective, there is a randomized controlled trial coming soon to confirm if there is merit in these preliminary findings.
Lots of exciting developments in this realm. Email me if you’d like access to some of the blogs.
