In more detail, we assessed whether chronic vestibulopathy leads to (a) deficits in vestibular tasks without cognitive demand (balancing), (b) deficits in spatial cognitive tasks that require vestibular input (path integration, rotational memory), (c) deficits in spatial cognitive tasks that do not rely on vestibular input, (d) deficits in general cognitive function, and (e) atrophy in the brain. Methods: A total of 15 patients with chronic uni- or bilateral vestibulopathy (56.8 \u00b1 10.1 years; 4 females) were included in this study and were age- and gender-matched by the control participants (57.6 \u00b1 10.5) in a pairwise manner. Given their clinical symptoms and their deficits of the vestibulo-ocular reflex (VOR) the patients could be classified as being mildly affected. All participants of the underwent the following tests: clinical balance (CBT), triangle completion (TCT) for path integration, rotational memory (RM), the visuo-spatial subset of the Berlin intelligence structure test (BIS-4) and d2-R for attention and concentration, and a structural MRI for gray matter analysis using voxel-based morphometry (VBM). Results: Compared to the healthy controls, the vestibulopathy patients performed significantly worse in terms of CBT, TCT, and RM but showed no differences in terms of the BIS-4 and d2-R. There were also no significant volumetric gray matter differences between the two groups. Conclusions: This study provides evidence that both non-cognitive and cognitive functions that rely on vestibular input (balancing, path integration, rotational memory) are impaired, even in mild chronic vestibulopathy, while other cognitive functions, which rely on visual input (visuo-spatial memory, attention), are unimpaired in this condition, together with an overall intact brain structure. These findings may reflect a segregation between vestibular- and visual-dependent processes in the medial temporal lobe on the one hand and a structure\u2013function dissociation on the other.<\/jats:p>","DOI":"10.3390\/life11121369","type":"journal-article","created":{"date-parts":[[2021,12,9]],"date-time":"2021-12-09T21:46:58Z","timestamp":1639086418000},"page":"1369","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Chronic, Mild Vestibulopathy Leads to Deficits in Spatial Tasks that Rely on Vestibular Input While Leaving Other Cognitive Functions and Brain Volumes Intact"],"prefix":"10.3390","volume":"11","author":[{"given":"Milos","family":"Dordevic","sequence":"first","affiliation":[{"name":"Neuroprotection Lab, German Center for Neurodegenerative Diseases, Leipziger Str. 44, 39120 Magdeburg, Germany"},{"name":"Department of Neurology, Otto von Guericke University, Leipziger Str. 44, 39120 Magdeburg, Germany"},{"name":"Center for Behavioral Brain Sciences, 39106 Magdeburg, Germany"},{"name":"Faculty of Health Sciences (FGW), University Potsdam, 14476 Potsdam, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sabrina","family":"Sulzer","sequence":"additional","affiliation":[{"name":"Neuroprotection Lab, German Center for Neurodegenerative Diseases, Leipziger Str. 44, 39120 Magdeburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Doreen","family":"Barche","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, Head and Neck Surgery, Otto von Guericke University, 39120 Magdeburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marianne","family":"Dieterich","sequence":"additional","affiliation":[{"name":"Department of Neurology, Ludwig-Maximilians University, Marchioninistra\u00dfe 15, 81377 Munich, Germany"},{"name":"Graduate School of Systemic Neuroscience (GSN), Ludwig-Maximilians University, 80336 Munich, Germany"},{"name":"German Center for Vertigo and Balance Disorders DSGZ-IFB LMU, Ludwig-Maximilians University, 80336 Munich, Germany"},{"name":"Munich Cluster for Systems Neurology (Synergy), 80336 Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8072-1438","authenticated-orcid":false,"given":"Christoph","family":"Arens","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, Head and Neck Surgery, Otto von Guericke University, 39120 Magdeburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5483-6423","authenticated-orcid":false,"given":"Notger G.","family":"M\u00fcller","sequence":"additional","affiliation":[{"name":"Neuroprotection Lab, German Center for Neurodegenerative Diseases, Leipziger Str. 44, 39120 Magdeburg, Germany"},{"name":"Department of Neurology, Otto von Guericke University, Leipziger Str. 44, 39120 Magdeburg, Germany"},{"name":"Center for Behavioral Brain Sciences, 39106 Magdeburg, Germany"},{"name":"Faculty of Health Sciences (FGW), University Potsdam, 14476 Potsdam, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"639","DOI":"10.1002\/lary.28877","article-title":"Peripheral Vestibular Disorders: Nationwide Evidence From Taiwan","volume":"131","author":"Yang","year":"2020","journal-title":"Laryngoscope"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"505","DOI":"10.1111\/j.1749-6632.2009.03765.x","article-title":"Causative factors, epidemiology, and follow-up of bilateral vestibulopathy","volume":"1164","author":"Zingler","year":"2009","journal-title":"Ann.
