Importantly, the headache needs to meet migraine diagnostic criteria on only 8 days a month in order to meet chronic migraine diagnostic criteria. When acute medication overuse is present, a second diagnosis of medication overuse headache should be made. If patients meet criteria for chronic migraine, this excludes a diagnosis of chronic tension\u2010type headache.<\/jats:p>\n                    <jats:p>Acute therapy of chronic migraine is similar to episodic migraine, except that medication overuse is a much greater risk in chronic migraine and must be addressed. All patients should be considered for pharmacological prophylaxis, and the behavioral aspects of therapy should be emphasized. The two prophylactic drugs with the best evidence for efficacy in chronic migraine are topiramate and onabotulinumtoxinA. Given the disability caused by chronic migraine, these should both be available to patients as necessary.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Management of chronic migraine is complex, and many patients are relatively refractory to therapy. Specialist referral will often be required and should not be unduly delayed. On the other hand, the primary care physician should be able to make the diagnosis, initiate therapy, and manage some less refractory patients without referral. The timing of referral should depend both on the expertise of the primary care physician in headache management and the patient's response to initial therapy.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/head.13089","type":"journal-article","created":{"date-parts":[[2017,5,26]],"date-time":"2017-05-26T08:45:12Z","timestamp":1495788312000},"page":"1471-1481","source":"Crossref","is-referenced-by-count":35,"title":["The Diagnosis and Management of Chronic Migraine in Primary Care"],"prefix":"10.1111","volume":"57","author":[{"given":"Werner J.","family":"Becker","sequence":"first","affiliation":[{"name":"Department of Clinical Neurosciences, Cumming School of Medicine University of Calgary Calgary Alberta Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,5,26]]},"reference":[{"key":"e_1_2_4_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-2982.2009.01941.x"},{"key":"e_1_2_4_3_1","doi-asserted-by":"publisher","DOI":"10.7861\/clinmedicine.15-4-344"},{"key":"e_1_2_4_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.mayocp.2015.01.010"},{"key":"e_1_2_4_5_1","doi-asserted-by":"crossref","unstructured":"The International Classification of Headache Disorders 3rd edition (beta version).Cephalalgia.2013;33:629\u2010808.","DOI":"10.1177\/0333102413485658"},{"key":"e_1_2_4_6_1","doi-asserted-by":"publisher","DOI":"10.1177\/0333102415583982"},{"key":"e_1_2_4_7_1","unstructured":"ChronicMigrainewww.mychronicmigraine.cawebsite @2015.
