Based on the response given by the caregiver to the Neuropsychiatric Inventory, patients were classified into AD with disturbed sleep (AD-DS) or AD without disturbed sleep (ADwDS). Cognitive performance and NPS were evaluated. Progression was evaluated with the \u0394-Mini-Mental State Examination (MMSE) (baseline MMSE-MMSE at 3-month follow-up). A sex stratified analysis was carried out.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>AD-DS performed worse than participants with ADwDS at all the cognitive tests. AD-DS presented more frequently depression, anxiety, aberrant motor behavior, disinhibition and eating disorders. At the sex-stratified analysis, AD-DS women were more frequently disinhibited and depressed than ADwDS. Men with AD-DS presented worse performances at several cognitive tests. Furthermore, various NPS were more frequent in men with AD-DS than in those with ADwDS, including hallucination, agitation, depression, and aberrant motor behavior. The burden was higher in caregivers of men belonging to the AD-DS group. Finally, at the linear regression, adjusting for age, education and MMSE at baseline, the presence of disturbed sleep was related to a more evident decline in MMSE in men (coeff. 2.5; 95%CI 0.72\u20134.29; p-value 0.006).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>DS was associated with several NPS, caregiver burden and, in men, faster cognitive decline progression.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/13872877251400783","type":"journal-article","created":{"date-parts":[[2025,12,4]],"date-time":"2025-12-04T14:46:21Z","timestamp":1764859581000},"page":"845-852","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Sex-specific sleep disturbances worsen psychiatric symptoms and cognitive decline in individuals with Alzheimer's disease"],"prefix":"10.1177","volume":"109","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8397-3478","authenticated-orcid":false,"given":"Antonina","family":"Luca","sequence":"first","affiliation":[{"name":"Department of Medicine and Surgery, Kore University of Enna, Enna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Luca","sequence":"additional","affiliation":[{"name":"Azienda Sanitaria Locale 3 (ASL 3), Centre for Addiction, Adrano-Bronte, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paolo","family":"Olgiati","sequence":"additional","affiliation":[{"name":"Department of Medicine and Surgery, Kore University of Enna, Enna, Italy"},{"name":"Oasi Research Institute-IRCCS, Troina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raffaele","family":"Ferri","sequence":"additional","affiliation":[{"name":"Oasi Research Institute-IRCCS, Troina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessandro","family":"Serretti","sequence":"additional","affiliation":[{"name":"Department of Medicine and Surgery, Kore University of Enna, Enna, Italy"},{"name":"Oasi Research Institute-IRCCS, Troina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,12,4]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/ene.13439"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jad.2015.09.069"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1177\/1533317517744061"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41386-019-0478-5"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1159\/000335363"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10072-014-1873-7"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1590\/1980-5764-dn-2023-0030"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(18)30450-2"},{"key":"e_1_3_3_10_2","article-title":"Sleep deprivation: a risk factor for the pathogenesis and progression of Alzheimer\u2019s disease","volume":"10","author":"Han Z","year":"2024","unstructured":"Han Z, Yang X, Huang S.
