My dad has all 3. What is his life expectancy as he is already 93? Dad had trach, feeding tube put in Dec. 2020. Difficulty swallowing, aspirating, gagging, coughing for over a year. Big weight loss also. ER 3 times for breathing difficulties Nov/Dec. of 2020. Diagnosed with P April 2021. Now on beginning dose of carbidopa-levodopa for 2 weeks. Dr. is hoping meds will help with pain in swallowing phlegm and facial tics. Any benefit to body tremors is a plus. Dad is housebound and my mom is his caretaker. They are both rockstars to me!
P.S. Dr. has said Parkinson's does not skip a generation. Has anyone seen generational Parkinson's in their family?
I wish you good luck. Stay in touch with your Dad's doctors. Follow your Dad's wishes regarding end of life care and how much longer he wants to fight this fight. He will be your guide, and when/if he is unable to make further decisions your Mom with all her devotion will step in. I am so sorry for all the grief you are in the midst of, but with that you have also been a witness to great love, and a participant in it. I wish you all well.
As to the comment about the hereditary nature of Parkinson's - as far as I know in most cases it isn't.
