I'm seronegative, and since I don't respond to Mestinon, and my response to IVIg and immunosuppressants is doubtful, I go through bouts of questioning my diagnosis.

My mother's sister just had what seemed to be a stroke, but they can't find any evidence of that through MRI's or CT-scans. She said she had sudden loss of balance and visual problems. That's all I know. She said she's recovering, but using a cane to walk. I have written to her to tell her to mention my situation to her neurologist and ophthalmologist.

I am 46 (I've had symptoms for 3 years) and my aunt is 65. If there was a congenital myasthenic syndrome in our family, you'd think it would have come out before now. My mother is 69 and doesn't any neuromuscular symptoms. Any ideas?
