Aspirin doesn't help memory loss

Does aspirin help to prevent memory loss if you're over 50?

We know that age related cognitive decline may be due to atherosclerosis, which aspirin helps to combat. But unfortunately, this well designed study didn't show any cognitive benefit in men and women over 50 who took daily low dose aspirin.

An editorial says that drugs that lower blood pressure are probably the best way of slowing vascular cognitive decline. Daily aspirin should be advised only for people at high risk of strokes or heart attacks and low risk of bleeding.
