Never really heard about this other than Michael J Fox has it. You would see him on tv and see the changes and say wow. When it effects a loved one. You are like what do I do? Where do I start? My mom who just got diagnosed with it. I wonder if I should have seen a sign? She is so different now, it's difficult to handle. Can't concentrate, not walking, hardly talking. I hope that being a part of this group can help me.
