One of my sisters has been diagosed with this condition that is incurable. It is simply a shrinking of the cerebellum and it destroys motor functions, slurs speech, later on it will not allow her to swallow. They say it is similar to Lou Gehrigs disease. She has been battling it for a number of years until she was diagnosed at the Mayo Clinic this past June. They have no idea how progressive it is; I guess each person is different. She is in assisted living as she wants to be as independent as possible for as long as she can. She is already walking with a walker and her speech is definitely slurred. She has to think really hard to form her words. My heart just aches for her. She keeps her spirits up and has been told she has added a lot already to their community at the assisted living facility. I just wonder if anyone has heard of this condition and if you would have anymore information about it. Mostly its progression. Thank, Cathy
