Little is known about its associations with other symptoms within the migraine phenotype. There is significant methodological heterogeneity and therefore inadequate overall evidence about the potential differences in efficacy of any migraine treatments in patients with problematic vertigo associated with migraine, compared to those without vertigo. Enhancing understanding of migraine\u2010related vertigo could help guide treatment and inform on mechanisms of vestibular migraine, a poorly understood diagnostic entity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Chronic migraine extended phenotypes of patients seen within the adult headache service at King's College Hospital Tertiary Headache Service between January 2014 and December 2021 (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u2009589) were extracted from the first documented clinic consultation letter retrospectively.
