Hello everybody! My Father was recently diagnosed as having PD.Since I have read that Progressive Supranuclear Palsy may mimic PD symptoms, I would like to know how both diseases could be distinguished at th early stage. I would be very grateful if you could give me some information or directions on how to get it. I have tried to get this information with neurologists but I haven't succeeded. Thanks Graziela ( [log in to unmask])
