One thousand three hundred fifty-two patients with a CDH (106 narcolepsy type 1, 90 narcolepsy type 2, 119 idiopathic hypersomnia, 192 nonorganic hypersomnia, 205 insufficient sleep syndrome), fatigue syndromes (n = 183), and a subgroup of patients with sleep apnea (n = 457) were analyzed. Classification based on SVT parameters was compared with the final clinical diagnosis serving as a reference.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>An overall model predicted the final diagnosis in 49.5% of patients. However, for the pairwise differentiation of two clinically suspected diagnoses, many SVT parameters showed a sensitivity and specificity above 70%. While the overall discrimination power of the multiple sleep latency test was slightly better than the one of the maintenance of wakefulness test, the latter differentiated best between narcolepsy and idiopathic hypersomnia with prolonged sleep need. Disproportionally poor results in reaction tests (e.g. steer clear test), despite comparable or lower sleepiness levels (SLAT, WLAT), were valuable for differentiating nonorganic hypersomnia from idiopathic hypersomnia\/sleep insufficiency syndrome.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study demonstrates how the combination of a careful clinical assessment and a selection of SVTs can improve the differentiation of CDH, whereas it was not possible to establish an overall prediction model based on SVTs alone.<\/jats:p><\/jats:sec>","DOI":"10.1093\/sleep\/zsac017","type":"journal-article","created":{"date-parts":[[2022,1,17]],"date-time":"2022-01-17T23:51:59Z","timestamp":1642463519000},"source":"Crossref","is-referenced-by-count":17,"title":["The diagnostic value of sleep and vigilance tests in central disorders of hypersomnolence"],"prefix":"10.1093","volume":"45","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3422-2715","authenticated-orcid":false,"given":"Johannes","family":"Mathis","sequence":"first","affiliation":[{"name":"Department of Neurology, Inselspital, Bern University Hospital, University of Bern, Bern, Switzerland"},{"name":"Sleep Medicine, Neurozentrum Bern, Bern, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6301-1784","authenticated-orcid":false,"given":"Daniel","family":"Andres","sequence":"additional","affiliation":[{"name":"Department of Neurology, Inselspital, Bern University Hospital, University of Bern, Bern, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5587-6240","authenticated-orcid":false,"given":"Wolfgang J","family":"Schmitt","sequence":"additional","affiliation":[{"name":"University Hospital of Psychiatry, University of Bern, Bern, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4535-0245","authenticated-orcid":false,"given":"Claudio L","family":"Bassetti","sequence":"additional","affiliation":[{"name":"Department of Neurology, Inselspital, Bern University Hospital, University of Bern, Bern, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian W","family":"Hess","sequence":"additional","affiliation":[{"name":"Department of Neurology, Inselspital, Bern University Hospital, University of Bern, Bern, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6088-2015","authenticated-orcid":false,"given":"David R","family":"Schreier","sequence":"additional","affiliation":[{"name":"Department of Neurology, Inselspital, Bern University Hospital, University of Bern, Bern, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2022,1,17]]},"reference":[{"key":"2022031409015312800_CIT0001","volume-title":"International Classification of Sleep Disorders","year":"2014","edition":"Third Edition"},{"issue":"3","key":"2022031409015312800_CIT0002","doi-asserted-by":"crossref","first-page":"307","DOI":"10.1111\/jsr.12383","article-title":"Which diagnostic findings in disorders with excessive daytime sleepiness are really helpful?
