Thanks a lot. I am impressed by your deep knowledge. I understand that only biopsy can examine nerve cell death but of course only for the biopsy material and not for the rest of the body.

Are there certain symptoms that are more likely to appear when cell is dead vs not, for example numbness, no fealing of cold and hot, paralysis, etc. ?

And if axons and myelin sheets can heal, why do so many neuropathies do not recover? is it that only very seldom the nerve cell stays intact when axons and myelin sheets are damaged? Or because it is often not possible to eliminate the cause (diabetes, ideopathic,...) ?

I am asking since my neuropathy is toxic, from chemotherapy. Unfortunatelly I have to continue chemo for 2 cycles and I wonder how to find out whether there is a chance of improvement after therapy or whether it well get even worse in the next cycles. And I thought the best is to understand which damage has actually already occured.
