This study aimed to investigate distinct sleep signatures in patients with benign paroxysmal positional vertigo (BPPV), vestibular migraine (VM), and persistent postural\u2010perceptual dizziness (PPPD) compared to healthy controls.\n                    <jats:bold>Methods<\/jats:bold>\n                    : We conducted a cross\u2010sectional study with 90 participants: 24 healthy controls, 21 with BPPV, 23 with PPPD, and 22 with VM. Sleep was assessed using a multimodal approach: 14\u2010day actigraphy, a single\u2010night home sleep apnea test (Watch\u2010PAT), and validated questionnaires, including the Pittsburgh Sleep Quality Index (PSQI), Dizziness Handicap Inventory (DHI), and Beck Anxiety\/Depression Inventories.\n                    <jats:bold>Results<\/jats:bold>\n                    : All dizziness groups reported significantly worse subjective sleep quality and higher psychological burden than controls. However, each disorder presented a unique objective signature:\n                    <jats:bold>BPPV<\/jats:bold>\n                    : Characterized by objective sleep fragmentation and a markedly higher Apnea\u2010Hypopnea Index (AHI: 31.5) and Oxygen Desaturation Index (ODI: 16). These patients also showed increased nocturnal restlessness (L5).\n                    <jats:bold>PPPD<\/jats:bold>\n                    : Demonstrated a \u201csleep paradox\u201d with the highest objective sleep efficiency but the poorest subjective perception (PSQI: 11.0). Patients showed reduced daytime activity (M10) and rigid sleep routines with virtually no weekend\u2010weekday get\u2010up time difference.\n                    <jats:bold>VM<\/jats:bold>\n                    : Distinguished by the shortest total sleep time and pronounced, though not statistically significant, \u201csocial jetlag\u201d, reflected by a 120\u2010min discrepancy between weekend and weekday get\u2010up times.\n                    <jats:bold>Conclusion<\/jats:bold>\n                    : Dizziness is not a homogeneous entity regarding sleep. The distinct signatures found suggest that clinical management should be tailored: screening for sleep apnea in BPPV, addressing the objective\u2010subjective disconnect in PPPD via cognitive\u2010behavioral approaches, and managing sleep deprivation and circadian regularity in VM.\n                  <\/jats:p>","DOI":"10.1002\/brb3.71863","type":"journal-article","created":{"date-parts":[[2026,10,21]],"date-time":"2026-10-21T06:06:42Z","timestamp":1792562802000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Sleep in Different Types of Dizziness"],"prefix":"10.1002","volume":"16","author":[{"given":"Lucia","family":"Joffily","sequence":"first","affiliation":[{"name":"Department of Neurology Universidade Federal Do Rio de Janeiro (UFRJ)  Rio de Janeiro Brazil"},{"name":"SENSE Research Unit, Department of Clinical and Movement Neurosciences, Institute of Neurology University College London  London UK"},{"name":"Department of Otolaryngology Universidade Federal Do Estado Do Rio de Janeiro (UNIRIO)  Rio de Janeiro Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco Ant\u00f4nio Sales Dantas","family":"de Lima","sequence":"additional","affiliation":[{"name":"Department of Neurology Universidade Federal Do Rio de Janeiro (UFRJ)  Rio de Janeiro Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John Fontenele","family":"Ara\u00fajo","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio De Neuroci\u00eancia e Psicologia Social \u2010 LaNPSo Universidade Federal do Delta do, Parna\u00edba \u2013 UFDPar, Rio de Janeiro, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diego","family":"Kaski","sequence":"additional","affiliation":[{"name":"SENSE Research Unit, Department of Clinical and Movement Neurosciences, Institute of Neurology University College London  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,20]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.31887\/DCNS.2003.5.4\/vabad"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1080\/23279095.2025.2548011"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1177\/0194599816689667"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/0165\u20101781(89)90047\u20104"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1526\u20104610.2007.00780.x"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.3109\/00016480903431139"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00415\u2010008\u20100697\u2010x"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1053\/smrv.2002.0253"},{"issue":"6","key":"e_1_2_10_10_1","first-page":"281","article-title":"Obstructive Sleep Apnoea Syndrome (OSAS): Effects on the Vestibular System","volume":"30","author":"Gallina S.","year":"2010","journal-title":"Acta Otorhinolaryngologica It\u00e1lica"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.smrv.2014.06.002"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.slsci.2014.09.013"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jsmc.2020.02.017"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1990.01870040046011"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.1177\/09574271251318971"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215123002153"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1526\u20104610.2005.05159.x"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00415\u2010024\u201012652\u20102"},{"key":"e_1_2_10_19_1","doi-asserted-by":"publisher","DOI":"10.3233\/VES\u20102012\u20100453"},{"key":"e_1_2_10_20_1","doi-asserted-by":"publisher","DOI":"10.3390\/medicina59030471"},{"key":"e_1_2_10_21_1","doi-asserted-by":"publisher","DOI":"10.12122\/j.issn.1673\u20104254.2020.01.21"},{"key":"e_1_2_10_22_1","doi-asserted-by":"publisher","DOI":"10.1055\/s\u20100042\u20101742763"},{"key":"e_1_2_10_23_1","first-page":"67","volume-title":"Handbook of Clinical Neurology","author":"Neuhauser H.
