"Is it possible that the BETonMACE trial will know which patients in sub-group for VD actually have Alzheimer's,...?"
One could not determine this from MoCA scores alone. I have no idea if BETonMACE trial protocol includes further genetic, imaging, or laboratory tests in these 467 patients 70 years or older to ascertain more detailed info in those with cognitive impairment at baseline.
