The definition on my records is of sensory, axonal, polyneuropathy of a length-dependent, type exhibiting on both sides (L&R feet/legs) of approximate equal nature.
I was told that if it was only one side it would be mononeuropathy.
Old school definition? The neuro was in his 70's.
He also saw that I had been hospitalized for pancreatitis and immediately determined the cause was AN (alcoholic neuropathy) without going any further in investigating other probable causes.
He also was of the opinion that PN in non-diabetics, was usually caused by...... pre-diabetes, when no other causal factor could be proven.
