I just wanted to share this with you. Bob, my husband was diagnosed by his neurologist at the movement disorder clinic in Calgary. She made the diagnosis of PSP, and sent the information to the GP here. Every visit to the GP, he was calling this pseudo bulbar palsy, not progressive supra nuclear palsy. There is always so much going on at these appointments, I never had the opportunity to question why. With the internet, I searched pseudo bulbar palsy, and found it is indeed a 'group of symptoms', that is common in several neurological disorders. If I remember correctly, they had listed ALS, MSA, MS, PSP, and some others. I'm assuming that those are the symptoms in which the GP has most concern. Not a real helpful bit of info, but I thought it may be of interest to some.
