When symptoms are present, headache is the most frequent presenting feature, although symptoms can be variable. The purpose of this review is to help primary care clinicians better understand the relationship between an individual's presenting symptoms and the presence of radiographic CM1, and to describe the expected outcomes for patients who undergo decompression surgery.<\/jats:p>\n <\/jats:sec>\n \n Recent findings<\/jats:title>\n Recent literature has shown that asymptomatic patients with CM1 tend to have a benign natural history. For symptomatic Chiari malformation, headache is the most common presenting symptom and the majority of patients that present with headache will have symptom improvement after foramen magnum decompression. This improvement is most reliable for patients with classic Chiari-type headache, which are described as occipital or cervical and tussive in nature, but has also been shown in patients with atypical headaches who have undergone surgery.<\/jats:p>\n <\/jats:sec>\n \n Summary<\/jats:title>\n CM1 is a common radiographic finding and associated symptoms can be variable. The relevance of this finding to a particular patient and need for intervention must be made on an individual basis.<\/jats:p>\n <\/jats:sec>","DOI":"10.1097\/mop.0000000000000679","type":"journal-article","created":{"date-parts":[[2018,8,23]],"date-time":"2018-08-23T01:03:54Z","timestamp":1534986234000},"page":"786-790","source":"Crossref","is-referenced-by-count":13,"title":["Headache, Chiari I malformation and foramen magnum decompression"],"prefix":"10.1097","volume":"30","author":[{"given":"Adam M.","family":"Olszewski","sequence":"first","affiliation":[{"name":"Division of Neurosurgery, University of Vermont Medical Center, Burlington, Vermont"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark R.","family":"Proctor","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Boston Children's Hospital, Harvard Medical School, Boston, Massachusetts, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-20230918","doi-asserted-by":"crossref","first-page":"293","DOI":"10.1055\/s-0036-1584563","article-title":"Chiari type 1 deformity in children: pathogenetic, clinical, neuroimaging, and management aspects","volume":"47","author":"Poretti","year":"2016","journal-title":"Neuropediatrics"},{"key":"R2-20230918","doi-asserted-by":"crossref","first-page":"238","DOI":"10.1136\/archdischild-2016-310662","article-title":"Headache outcomes in children undergoing foramen magnum decompression for Chiari I malformation","volume":"102","author":"Raza-Knight","year":"2017","journal-title":"Arch Dis Child"},{"key":"R3-20230918","doi-asserted-by":"crossref","first-page":"65","DOI":"10.3171\/2017.8.PEDS17345","article-title":"Morphometric and volumetric comparison of 102 children with symptomatic and asymptomatic Chiari malformation type I","volume":"21","author":"Khalsa","year":"2018","journal-title":"J Neurosurg Pediatr"},{"key":"R4-20230918","doi-asserted-by":"crossref","first-page":"S95","DOI":"10.1007\/s10072-017-2950-5","article-title":"Chiari malformation-related headache: outcome after surgical treatment","volume":"38","author":"Beretta","year":"2017","journal-title":"Neurol Sci"},{"key":"R5-20230918","doi-asserted-by":"crossref","first-page":"133","DOI":"10.1097\/JSM.0000000000000107","article-title":"The risk of athletes with Chiari malformations suffering catastrophic injuries during sports participation is low","volume":"25","author":"Meehan","year":"2015","journal-title":"Clin J Sport Med"},{"key":"R6-20230918","doi-asserted-by":"crossref","first-page":"S91","DOI":"10.1007\/s10072-017-2915-8","article-title":"Chiari malformation type 1-related headache: the importance of a multidisciplinary study","volume":"38","author":"Curone","year":"2017","journal-title":"Neurol Sci"},{"key":"R7-20230918","doi-asserted-by":"crossref","first-page":"511","DOI":"10.3171\/2016.11.PEDS16263","article-title":"Comparison of posterior fossa volumes and clinical outcomes after decompression of Chiari malformation type I","volume":"19","author":"Khalsa","year":"2017","journal-title":"J Neurosurg Pediatr"},{"key":"R8-20230918","doi-asserted-by":"crossref","first-page":"403","DOI":"10.3171\/2015.8.PEDS15188","article-title":"Sports participation with Chiari I malformation","volume":"17","author":"Strahle","year":"2016","journal-title":"J Neurosurg Pediatr"},{"key":"R9-20230918","doi-asserted-by":"crossref","first-page":"213","DOI":"10.1016\/j.wneu.2017.04.082","article-title":"Chiari malformation type I: a systematic review of natural history and conservative management","volume":"104","author":"Landridge","year":"2017","journal-title":"World Neurosurg"}],"container-title":["Current Opinion in Pediatrics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.lww.com\/00008480-201812000-00015","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,18]],"date-time":"2023-09-18T02:24:35Z","timestamp":1695003875000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.lww.com\/00008480-201812000-00015"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,12]]},"references-count":9,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2018]]}},"URL":"https:\/\/doi.org\/10.1097\/mop.0000000000000679","relation":{},"ISSN":["1040-8703","1531-698X"],"issn-type":[{"value":"1040-8703","type":"print"},{"value":"1531-698X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,12]]}}}
