I'm so glad to hear that you have an appointment scheduled later this month, @oldsuzanne55. Yes, a Parkinson's specialist would be a good idea. This type of specialist would be called a Movement Disorder Specialist. It is a specific type of neurologist who specializes in movement disorders, Parkinson's being one of many movement disorders.

It sounds like a change in his meds (either the dosage or the frequency) would be helpful at this point, but the doctor can make that decision.

Here is a discussion group about tips for meeting with a new specialist that you might find helpful,

Will you post again after your appointment on the 15th? If you have any other thoughts or questions before then, please post them here.
