Thickened arteries alone don't really sound like vascular dementia, which should involve more hemmorages. In his case, calcification and atherosclerotic plaque come to mind, which can be treated to some effect with vitamin K2 and olive oil. But if he gets an actual diagnosis of vascular dementia, then Google "bone marrow vascular dementia" and you'll get a pile of studies on using bone marrow (not necessarily involving bone surgery) to improve brain function in such patients; in that case, you might get some clinically significant effects from Neupogen injections alone.
I also suggest looking into Gerson therapy or various other vegetable juicing protocols. (Gerson therapy has some flaws, in my view, but the essence of it makes good scientific sense.) For example, see this YouTube video on an informal juicing therapy trial. The hardcore approach would involve either juicing combined with caloric restriction, or a calorically unrestricted ketogenic diet with liberal doses of medium chain tryglycerides.
There are also a myriad of supplements that could help here, such as carbon 60 olive oil, nicotinamide riboside, ashitaba, xanthohumol, and pterostilbene. Those are all broad-spectrum antiaging substances, but other more targetted approaches would help as well, if only we had more information on the specific pathology involved. I would not, however, recommend blood thinners such as aspirin, vitamin E, or honokiol at this point, as if in fact he has vascular dementia, they would tend to increase the risk of hemmoragic stroke. Likewise for olive oil, except that it increases HDL cholesterol, which could help to diminish the arterial plaques.
By the way, plain curcumin is useless. Have a look at Longvida or other highly bioavailable curcumin supplements.
