As we all know on this site, it is extremely difficult to explain to people what PSP actually is. I find that carrying a supply of the printed information cards available from the PSP On-Line shop helps. I hand these out to anyone who asks about the illness (even those who don't sometimes!) so that we can spread the word about this very cruel and debilitating illness. I am of the opinion that the more people who know about the illness the more likely we are to generate enough interest into getting more research done to find treatment and ultimately a cure.
For anyone who is not aware already, these cards are free from the PSP On-Line Shop.
