Apologies.
I agree, there are some posts on this that refer to your question. I think though that when one asks a doctor as I did if some of my symptoms are related to the brainstem being pushed, they either don't know, or can't be sure. I have high blood pressure, but is that 'normal' or brainstem related? I choke a lot when eating certain things, is that brainstem related or not? I sleep badly and much less than I used to, what's that from? I have no answers to any of these, nor do my docs it seems. That of course does not mean that these are NOT brainstem pushing related. I must add that my brainstem is only slightly pushed, so it does not affect anything, I was told. Does it not? I wonder.
My mother died of a neurological problem, Multiple Systems Atrophy, which was explained to us as a degeneration of her brainstem. She ended up speechless, paralysed, unable to swallow, high blood pressure and high heart rate. Heart was the second last system to give up, and killed her. Breathing would have been next, fortunately she was spared asphyxiation.
I did have a friend with an inoperable 6cm AN that eventually ended up paralyzed and unable to speak and swallow and eventually breathe. She died in '04.
BUT, these are extreme cases! I just use them as an indication of the things that went wrong with their brainstem problem.
I think you need to ask the question to your doctors and see what they say.
