We tested 18 people with dissociative disorders not otherwise specified (DDNOS; compared with a matched sample of 18 healthy controls) undergoing a stress-inducing facial mirror confrontation paradigm, and measured acute dissociation and frontal electroencephalography (measured with a four-channel system) per experimental condition (e.g. confrontation with negative cognition). Linear mixed models indicated a significant group\u00d7time\u00d7condition effect, with DDNOS group depicting less electroencephalography power than healthy controls at the beginning of mirror confrontation combined with negative and positive cognition. This discrepancy \u2013 most prominent in the negative condition \u2013 diminished in the second minute. Correlational analyses depicted a positive association between initial electroencephalography power and acute dissociation in the DDNOS group. These preliminary findings may indicate altered neural processing in DDNOS, but require further investigation with more precise electroencephalography measures.<\/jats:p>","DOI":"10.1192\/bjo.2022.593","type":"journal-article","created":{"date-parts":[[2022,11,10]],"date-time":"2022-11-10T07:39:23Z","timestamp":1668065963000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":7,"title":["Altered frontal electroencephalography as a potential correlate of acute dissociation in dissociative disorders: novel findings from a mirror confrontation study"],"prefix":"10.1192","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2380-4848","authenticated-orcid":false,"given":"Eva","family":"Sch\u00e4flein","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2760-0896","authenticated-orcid":false,"given":"Yoki Linn","family":"Mertens","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6339-1078","authenticated-orcid":false,"given":"Nena","family":"Lejko","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1512-0817","authenticated-orcid":false,"given":"Sarah","family":"Beutler","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5378-4628","authenticated-orcid":false,"given":"Heribert","family":"Sattel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Sack","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"170","published-online":{"date-parts":[[2022,11,10]]},"reference":[{"key":"S2056472422005932_ref12","doi-asserted-by":"publisher","DOI":"10.1002\/brb3.2200"},{"key":"S2056472422005932_ref1","doi-asserted-by":"crossref","first-page":"898","DOI":"10.1016\/S0006-3223(98)00015-8","article-title":"Depersonalization: neurobiological perspectives","volume":"44","author":"Sierra","year":"1998","journal-title":"Biol Psychiatry"},{"key":"S2056472422005932_ref5","doi-asserted-by":"publisher","DOI":"10.1503\/jpn.090022"},{"key":"S2056472422005932_ref4","doi-asserted-by":"publisher","DOI":"10.1002\/jts.20284"},{"key":"S2056472422005932_ref3","doi-asserted-by":"publisher","DOI":"10.1017\/S0033291708002742"},{"key":"S2056472422005932_ref9","doi-asserted-by":"crossref","first-page":"449","DOI":"10.1007\/s00406-013-0461-9","article-title":"Memories of attachment hamper EEG cortical connectivity in dissociative patients","volume":"264","author":"Farina","year":"2014","journal-title":"Eur Arch Psychiatry Clin Neurosci"},{"key":"S2056472422005932_ref14","doi-asserted-by":"publisher","DOI":"10.1080\/20008198.2018.1472991"},{"key":"S2056472422005932_ref2","doi-asserted-by":"crossref","first-page":"640","DOI":"10.1176\/appi.ajp.2009.09081168","article-title":"Emotion modulation in PTSD: clinical and neurobiological evidence for a dissociative subtype","volume":"167","author":"Lanius","year":"2010","journal-title":"Am J Psychiatry"},{"key":"S2056472422005932_ref15","unstructured":"15 Gast, U , Z\u00fcndorf, F , Hofmann, A .
