Thanks so much for the response Kathrynne, Charlie and Michel. Our new neuro does specialize in PD. We have an appointment the end of September (as soon as we could get it) with a specialist in neuropsychiatry. Infection was ruled out. But George was told to drink a lot more water. A cat scan is set up for next week. No MRI because of pacemaker. Thanks to you all. Grace By the way, Kathrynne I have sent for your book.
