My father also has Parkinsons, he's not in the last stages but its difficult. I'm afraid there is no cure right now but it is definitely possible to have one in the future. I'm supporting the Michael J. Fox Parkinsons Foundation which funds research into finding a cure for Parkinsons and scientists have actually said that a cure can be found in the very near future but the problem is mainly money so that's what Michael J. Fox is helping with.
