In postmenopausal women greater than sixty years of age, a formononetin rich isoflavone supplement from red clover (Rimostil) daily for a period of six months failed to alter attention processing (Trail making tests) and had a small improvement in the block design test (visual spatial reasoning) yet failed to influence most parameters while placebo tended to outperform on a digit span test and in a verbal memory test.
