I was diagnosed 16 months ago. I am 78 now. Is this a progressive disease? My mom had Parkinson's disease. My brother developed the same disease along with diabetes. My mom had both diseases. I know that genetics is involved in the transmission of diseases. I am truly grateful I do not have diabetes. Not as of yet. MG, so far, has been manageable. A lot of eye twitching. Some arm and leg weakness. The breathing part is scary. Right now it is okay. Thank God!
