I guess I should clarify the "progressive" statement.
Some people with MG get diagnosed early on. They get drugs that help stop the antibody process and, therefore, the destruction at the neuromuscular junction.
Then there are people like me who weren't diagnosed well or soon enough and have relatively more damage.
Some research says that the damage is only about 1/3 of the junction. Others say it is indeed progressive and can damage the entire area! Now, please remember that I am not a doctor. Although I have read umpteen articles, books, etc. from medical libraries on this.
One more thing about this acetylcholine thing. You have less of it as you age. So, even if your disease process levels off, you will get less muscle juice as you get older.
Yeah, Lizzie, as you can tell I totally disagree that it's not progressive!

And no two people are alike. I don't think anyone can really generalize about people with MG. It would be nice if we - or our disease - were all that simple!!!
