We employed nerve ultrasound to assess the size of the vagus nerve in a serial study of patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and Charcot\u2010Marie\u2010Tooth type 1B (CMT1B) as compared to healthy controls (HCs). We correlated these findings with involvement of the median and ulnar nerves.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p>Forty\u2010three patients with CIDP, 8 with CMT1A, and 105 HC were prospectively recruited. The cross\u2010sectional areas (CSAs) of the vagus, median, and ulnar nerves were measured bilaterally. The alteration of CSA of those nerves was followed longitudinally in CIDP.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>The median (range) CSA of the vagus nerve was 2 (1\u201028) mm<jats:sup>2<\/jats:sup> in CIDP, 3 (2\u20106) mm<jats:sup>2<\/jats:sup> in CMT1A, and 1 (1\u20102) mm<jats:sup>2<\/jats:sup> in HC. The vagus nerve CSA was positively correlated with the maximum CSA of median\/ulnar nerve in CIDP and CMT1A. The alteration in vagus nerve CSA was positively correlated with the alteration in mean median\/ulnar nerve CSA in CIDP during follow\u2010up.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>The vagus nerve was involved to a similar extent as the median and ulnar nerves in CIDP and CMT1A, although no symptoms or signs of vagus nerve involvement were found. Further study should be performed to explore the clinical relevance of vagus nerve enlargement in these disorders.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jon.12747","type":"journal-article","created":{"date-parts":[[2020,6,27]],"date-time":"2020-06-27T19:01:25Z","timestamp":1593284485000},"page":"910-916","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Vagus
