I was diagnosed with progressive supranuclear palsy 5 years ago. Are there any good clinical trials available for psp?

Try this. Psp is frustrating and unfortnately progressive. Also, there just aren't many doctors with a ton of experience with this "rare" condition. See: http://www.Pspinformation.Com/ you may be able to find what you are looking for, or at least get connected to a support network.
