It sounds to me that a diagnosis of PD is more or less process of elimination. If all other options are ruled out, it must be PD.
Does anyone know the main difference between PD and PS?

Hi,
You are spot on. Yes, PD is primarily a diagnosis by exclusion.
I think by PS you mean Progressive Supranuclear Palsy or PSP? From what I understand though there is some overlap in symptoms, largely tremor is absent from PSP. Please see the following sites for more info:
