Star, I don't know how to link to another thread on the site, so I've copied something Tillie wrote on one of my threads. As I understand this, using the bipap does not increase his dependence on it, but it will make him feel better and help all of his systems function better, which may in fact help his rate of progression.
Ultimately, the PALS must make the choice. If you insure that your parents are knowledgeable about their choices that may be all that you can do. Sometimes the choice comes down to accepting a shorter life in return for doing what they want in the present. That's a hard one for us, but it's also a difficult decision to argue with--so long as they understand the choice they are making.

From Tillie:
" The studies apparently show that using bipap early gives far more effect than waiting until breathing is very low.
I don't know that it prolongs life for our PALS by a large amount, but I do know that it improves the quality of life enormously.
If a PALS is having trouble breathing this is going to have to impact on every other area of progression - they will have less energy, walking will be harder, falls more likely due to the extra fatigue and being less focused. You know how much harder everything is if you are really tired, so add that to trying to use wasted and/or spastic muscles.
So the more you can help the breathing, the better the quality they will have, and maybe affect progression by being safer and having oxygen saturated muscles rather than CO2 saturated ones.
I would go the sip and puff!
This is where Chris always wanted everything only when there was no other option. So he was emaciated and dehydrated and barely consuming any calories by the time he took the peg. The peg never helped him that much as a result.
He finally requested bipap only 2.5 weeks before he passed, after a pneumonia. Too late and we had to abandon even considering it.
So go early for everything, it will give better quality at the least!
