For many people, mental fatigue is one of the most distressing and long-lasting symptoms following an mTBI. No efficient treatment options can be offered. The best method for measuring fatigue today is with fatigue self-assessment scales, there being no objective clinical tests available for mental fatigue. The aim here is to provide a narrative review and identify fatigue in relation to cognitive tests and brain imaging methods. Suggestions for future research are presented.<\/jats:p>","DOI":"10.3390\/ijerph18115955","type":"journal-article","created":{"date-parts":[[2021,6,2]],"date-time":"2021-06-02T10:38:39Z","timestamp":1622630319000},"page":"5955","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Mental Fatigue after Mild Traumatic Brain Injury in Relation to Cognitive Tests and Brain Imaging Methods"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8942-5771","authenticated-orcid":false,"given":"Birgitta","family":"Johansson","sequence":"first","affiliation":[{"name":"Institute of Neuroscience and Physiology, The Sahlgrenska Academy, University of Gothenburg, 413 45 G\u00f6teborg, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"283","DOI":"10.1016\/j.annrmp.2006.04.017","article-title":"Fatigue and traumatic brain injury","volume":"49","author":"Belmont","year":"2006","journal-title":"Ann.
