nugget. It shows that researchers have actually discovered the reality of "chemo-brain," the often experienced side effect of chemotherapy which results on loss of mental clarity/sharpness, short-term memory loss, and, for some, an emotional roller coaster of moods. While it doesn't really matter to me whether chemo brain is validated medically, I am just glad that for many who experience it there is science backing up their claims.
I know what I deal with as the side effects of my treatment, and am not too worried if others (non-medical practitioners) do not believe me or understand them. So, there you go, it IS real and not just the mass hysteria or psychological acceptance of rumored side effects we in treatment convince ourselves we are experiencing.
