I have noticed with my sister changes in her behaviour. This disease of PSP has so many facets to it - every sufferer is different but there is always a common thread. Never feel embarassed about anything you write on this site because we have all opened our hearts at times when we have needed "a shoulder to cry on and for support". So little is known about PSP by the general public on this site we support each other. I have learnt more from fellow bloggers, picked up tips etc than from health professionals. Just keep blogging!
Best of luck
