Sick leave or reduced performance due to headache attacks demands flexibility by their social counterparts. The objective of this study is to test the hypothesis that headache patients cause frustration that grows with the times colleagues have to take over their work. In this study, we analysed cluster headache patients\u2019 answers to an online questionnaire. Participants self-reported their number of sick days, the number of days on which leisure activities were missed and whether they felt understood by colleagues and family. We then investigated the correlation between the number of sick days and the proportion of patients feeling understood by colleagues and friends. We found that feeling understood by colleagues and friends decreases with a growing number of sick days. However, when sick days accrue further, this proportion increases again. The number of sick days correlates similarly with both colleagues\u2019 and friends\u2019 understanding. The number of cluster headache patients feeling understood by others decreases with an increasing number of sick days. Their social circles\u2019 frustration with the patients\u2019 failure to meet obligations and expectations are a likely reason. With a growing number of sick days, however, the portion of patients feeling understood rises again despite patients meeting others\u2019 expectations even less. This \u2018comprehension paradox\u2019 implies the influence of other factors. We suspect that growing numbers of sick days foster understanding as the disability of the disease becomes increasingly apparent.<\/jats:p>","DOI":"10.1007\/s42399-021-01083-z","type":"journal-article","created":{"date-parts":[[2022,1,10]],"date-time":"2022-01-10T04:14:24Z","timestamp":1641788064000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Cluster Headache and the Comprehension Paradox"],"prefix":"10.1007","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2778-6790","authenticated-orcid":false,"given":"Heiko","family":"Pohl","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreas R.","family":"Gantenbein","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter S.","family":"Sandor","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean","family":"Schoenen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Colette","family":"Andr\u00e9e","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,1,10]]},"reference":[{"key":"1083_CR1","volume-title":"Behavioral neurobiology of eating disorders","author":"A RaH","year":"2011","unstructured":"RaH A, Kaye WH.
