Questions remain about recovery prognosis and the extent to which symptom resolution coincides with injury resolution. This study therefore investigated the electrophysiological differences in recoveries between simple and complex concussion. METHODS: Student athletes with acute concussion from a previous study (19(2) years old) were tracked from pre-injury baseline, 24\u201348 hours after concussion, and through in-season recovery. The electroencephalography (EEG) with P300 evoked response trajectories from this acute study were compared to an age-matched population of 71 patients (18(2) years old) with prolonged post-concussive symptoms (PPCS), 61 (SD 31) days after concussion. RESULTS: Acute, return-to-play, and PPCS groups all experienced a significant deficit in P300 amplitude compared to the pre-injury baseline group. The PPCS group, however, had significantly different EEG spectral and coherence patterns from every other group. CONCLUSION: These data suggest that while the evoked response potentials deficits of simple concussion may persist in more prolonged stages, there are certain EEG measures unique to PPCS. These metrics are readily accessible to clinicians and may provide useful parameters to help predict trajectories, characterize injury (phenotype), and track the course of injury.<\/jats:p>","DOI":"10.3233\/prm-210114","type":"journal-article","created":{"date-parts":[[2023,1,24]],"date-time":"2023-01-24T12:50:09Z","timestamp":1674564609000},"page":"287-299","source":"Crossref","is-referenced-by-count":6,"title":["Electrophysiological trajectories of concussion recovery: From acute to prolonged stages in late teenagers"],"prefix":"10.1177","volume":"16","author":[{"given":"Mo","family":"Mortazavi","sequence":"first","affiliation":[{"name":"SPARCC Sports Medicine, Rehabilitation, and Concussion Center, Tucson, AZ, USA"},{"name":"Department of Pediatrics, Tucson Medical Center, Tucson, AZ, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesca Arese","family":"Lucini","sequence":"additional","affiliation":[{"name":"WAVi Research, Boulder, CO, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Joffe","sequence":"additional","affiliation":[{"name":"WAVi Research, Boulder, CO, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David S.","family":"Oakley","sequence":"additional","affiliation":[{"name":"WAVi Research, Boulder, CO, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","reference":[{"issue":"11","key":"10.3233\/PRM-210114_ref1","doi-asserted-by":"publisher","first-page":"836","DOI":"10.1136\/bjsports-2017-097699","article-title":"Consensus statement on concussion in sport-the 5(th) international conference on concussion in sport held in Berlin, October 2016","volume":"51","author":"McCrory","year":"2017","journal-title":"Br J Sports Med"},{"issue":"4","key":"10.3233\/PRM-210114_ref2","doi-asserted-by":"publisher","first-page":"213","DOI":"10.1136\/bjsports-2018-100338","article-title":"American Medical Society for Sports Medicine position statement on concussion in sport","volume":"53","author":"Harmon","year":"2019","journal-title":"Br J Sports Med"},{"issue":"3","key":"10.3233\/PRM-210114_ref3","doi-asserted-by":"publisher","first-page":"597","DOI":"10.1542\/peds.2010-2005","article-title":"American Academy of Pediatrics","volume":"126","author":"Halstead","year":"2010","journal-title":"Clinical report\u2013sport-related concussion in children and adolescents.
