I have a relative, male, over 65, who has recently began having the following symptoms: Weakness, short-term memory loss, unbalanced, scoots feet. Has had recent MRI, which they called & said was clear . We remember, from a couple year ago, about a commercial, which showed an older man, with similar symptoms & it was something that was controllable, with meds, but we cannot remember what the illness was...it was something that is not, usually, diagnosed, right away, according to the commercial...any idea what that commercial was
