Time to take a peek at Google News.
I took another look at The Cochrane Library.
A search for "Dementia NOT "Down Syndrome" NOT Vascular NOT Aids NOT carer and Reviews" produced only 31 results, compared to 44 back in the day when I wrote Dementia: A review of the evidence.
My own research led me to write Look after your brain.
Recently, I found Vitamin D Stimulates Amyloid Clearance in Alzheimer's, which also suggests that curcumin (found in Turmeric) is important in the fight against dementia.
