Sorry to hear about your father.I have had pd for 7 years that I know of.I am a 60 yr old male,and still fortunately able to work
Everyone is different with this disease,and although it progresses in all ;it does so at different rates.medications also differ with all.With some people getting good response with one med but not another.I'm currently on stalevo(comtan,sinemet)and mirapex.Often as this disease progresses meds must be increased,or changed.Hopefully your father is seeing a good neurologist,and is staying on top of the meds.You did not mention how old your father was?Wishing you and your father the best.Ed
