I would like any knowledge on what criteria I may be missing for my doctors to give me a diagnosis if in fact it is ALS. My thenar and feet muscles have atrophy. Two muscle biopsies show fiber type grouping and chronic denervation with reinnervation, positive Babinski, brisk reflex, nerve biopsy showing axonal neuropathy. I have had 4 EMG's and the last one was the only abnormal one. It was the only EMG where they warmed by body temp to normal first. The doctor who did the EMG said " I am only diagnosing you with distal axonal neuropathy right now". I was told by one neuro a few years ago that I had discrete damage to my motor neurons. I am tired of not knowing but suspecting what is wrong. Thank you!!
