I lost my father to Parkinson's disease a few months ago. The sorrow is great. The greatest sorrow began years before his death - he lost the ability to hug his little girl (me), he couldn't play with his new great-granddaughter because of his rigidity and his tremors frightened her, he couldn't tell his wife of 50 years "I love you" -- Stage V is complete debilitation - unable to swallow, unable to control bodily functions, unable to walk, unable to talk, unable to write....is this what your mother wants? - my father would have been first in line for a surgical procedure if it meant being able to return his little girl's hugs, playing with his great-granddaughter without fear, and celebrating his 50th wedding anniversary with his loving, devoted caregiver...research was several years too late for him...I, for one, pray your mother will reconsider...for the love of her family. - ByByBetty - Phoenix, AZ - child of Parkinsonian and missing him terribly.
