Just 5 quick questions which may have more complicated, longer answers: 1. Are the 5 stages of PD generally accepted as a helpful indicator of progression of PD in a patient? 2. Is there any consistency, within reason, of the length of each stage? 3. Where can I get descriptions of what to expect in stage 5? 4. What are the generally accepted practices to take care of a patient with PD stage 5? 5. Has anyone heard of Pick's Disease in conjunction with PD? As always, your information and comments are gratefully received. Regards, Robert McKone
