Its still only a theoretical measure we are talking about. Remember that the people here are the most als-checked population-group on the net... As minimum they have been to GP. After that neuro and some even after that, scannings. And the most hardcore anxieties have been thrue the whole thing more than once.And in all the panic that you have, you still forget that als is not dificult to rule out. It CAN be difficult to find, but thats becourse some are complaining about weird things that are going on, that could be all kind of things - in the beginning...But IF the 13% is right, then you have only 1:50.000.000 risk or something like that. But of course - someone has to be no. 2 or 3 on this planet... But its not going to be you, sorry.
