You are so right. It is a horrible disease and no one should have to suffer with this. My dad is 77 and some people say...well, you're lucky you've had him this long. It hurts, I think, no matter the age or relationship you have with the patient.
My had has lost the use of his legs, left arm and suffers greatly with other symptoms. To him, he has lost his dignity and independence - this past year he has went from an active life to an invalid. He says no man should have to live like this. He is right.
My heart goes out to you and everyone else in this forum. It is difficult to put on a brave front as a caregiver - each moment that I spend with my dad is precious, but I think we are all crying on the inside.
Take care.
