Becky,
I may be out of line here ---but for lack of better words this doctor was a complete jerk !!!
MRI's in people diagnosed with ALS look normal --so it was more than a weird thing for him to say --
I am not a doctor nor even a nurse -- my husband has had ALS for 8 years -
But , I will say this -- this doctor was giving opinions in something he did not specialize in ---
So his opinion with you being asymptomatic of ALS -- is absolutely worthless and uncredible --as you can not diagnos ALS on an MRi -
MRI 's are used to rule other things out when neurological damage is observed in a physical exam or when other conditions are suspected-- but it is not a diiagnostic test to identify ALS itself --
Migranes are also not a symptom of ALS--
Sorry - but I 'm quite upset at what this man -- physician or not-- said to you -- totally unprofessional --as he is totally out of his league and is not a specialist in ALS--
