Speech intelligibility declines with age and sensorineural hearing damage (SNHL). However, it remains unclear whether cochlear synaptopathy (CS), a recently discovered form of SNHL, significantly contributes to this issue. CS refers to damaged auditory-nerve synapses that innervate the inner hair cells and there is currently no go-to diagnostic test available.

Nerve vasculitis can be divided into two categories based on vessel size - large arteriole vasculitis (≥75 µm) and microvasculitis (<75 µm). Herein, we characterize the clinical features of nerve large-arteriole vasculitis compared to nerve microvasculitis.

Anti-MAG patients go unrecognized when IgM-gammopathy is undetected or with atypical phenotypes. We investigated an optimal anti-MAG titration cutoff for excluding CIDP and the impact of IgM-gammopathy detection on neuropathy treatment evaluation without anti-MAG antibodies.

This report details and compares the neurologic clinicopathologic characteristics of these 2 groups.
Methods: This retrospective study was performed on patients diagnosed with pathologically confirmed NL in nerve between January 1, 1992, and June 31, 2020.
