I knew it before diagnosis myself. I got a second opinion from Dr Bril. She thought it was MMN. I didn't like her lack of compassion so got sent to the
ALS Clinic at Sunnybrook. They concluded
ALS as did my first Neuro. I got a fourth opinion from a guy at St. Mikes. Can't think of the guy's name but he's like House but in Toronto. My own personal opinion is that Zinman at Sunnybrook is smarter than Bril. I'd see him for second opinion when the time comes.
