Symptoms associated with headache\u2014photophobia and phonophobia, nausea, and\/or vomiting\u2014are required criteria for the diagnosis of migraine. Individuals with migraine also report high rates of other symptoms (e.g. lightheadedness, difficulty thinking). We have developed cluster analysis of migraine-associated symptoms (CAMS), which is a composite representation of an expanded set of migraine-associated symptoms that is associated with headache burden. It is unknown if CAMS can change with treatment response or predict outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a secondary analysis of prospectively collected clinician-guided patient questionnaire data from youth (6\u201317 years) with migraine who were seen at a specialized pediatric headache clinic. Data were collected at time of presentation and at the first follow-up within 30 to 90 days from the first visit. CAMS were implemented to assess associations between 11 migraine-associated symptoms. We determined if CAMS changed over time and as a function of treatment outcome, and if CAMS could be used to predict outcome at first follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Youth with migraine (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u20098008, 67.1% female, median 13 years old) were included in this study. CAMS revealed that the number of reported migraine-associated symptoms decreased at follow-up, particularly for those who improved. Resolution of nausea and vomiting were most common. CAMS at the initial visit differed between youth who improved and youth who did not, but the effect was clinically negligible and could not reliably predict outcome (AUC 0.53).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Migraine-associated symptoms as captured by CAMS changed over time based on whether youth noted improvement or not but was not predictive of who improved at follow-up.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/25158163251371152","type":"journal-article","created":{"date-parts":[[2025,8,21]],"date-time":"2025-08-21T07:15:24Z","timestamp":1755760524000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Migraine-associated symptoms change with improvement in youth with migraine: A cohort study"],"prefix":"10.1177","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4996-2457","authenticated-orcid":false,"given":"Carlyn","family":"Patterson Gentile","sequence":"first","affiliation":[{"name":"Departments of Neurology and Pediatrics, Children\u2019s Hospital of Philadelphia and Perelman School of Medicine at the University of Pennsylvania, Philadelphia, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4786-8889","authenticated-orcid":false,"given":"Christina L.","family":"Szperka","sequence":"additional","affiliation":[{"name":"Departments of Neurology and Pediatrics, Children\u2019s Hospital of Philadelphia and Perelman School of Medicine at the University of Pennsylvania, Philadelphia, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1598-7536","authenticated-orcid":false,"given":"Andrew D.","family":"Hershey","sequence":"additional","affiliation":[{"name":"Departments of Pediatrics and Neurology, Cincinnati Children's Hospital Medical Center and University of Cincinnati College of Medicine, Cincinnati, OH, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,8,21]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1177\/0333102417738202"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-2982.2007.01421.x"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1526-4610.2005.00260.x"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1177\/0333102420921855"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.3233\/VES-201644"},{"key":"e_1_3_4_7_2","doi-asserted-by":"publisher","DOI":"10.1111\/head.12189"},{"key":"e_1_3_4_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1526-4610.2011.01934.x"},{"key":"e_1_3_4_9_2","doi-asserted-by":"publisher","DOI":"10.1111\/head.14484"},{"key":"e_1_3_4_10_2","doi-asserted-by":"publisher","DOI":"10.1111\/head.14430"},{"key":"e_1_3_4_11_2","doi-asserted-by":"publisher","DOI":"10.1111\/head.14315"},{"key":"e_1_3_4_12_2","doi-asserted-by":"publisher","DOI":"10.1177\/03331024231187162"},{"key":"e_1_3_4_13_2","doi-asserted-by":"publisher","DOI":"10.1111\/head.14859"},{"key":"e_1_3_4_14_2","doi-asserted-by":"publisher","DOI":"10.1111\/head.14858"},{"key":"e_1_3_4_15_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.57.11.2034"},{"key":"e_1_3_4_16_2","unstructured":"Patterson-Gentile C.
