“…Much of the literature in this area, however, has investigated the PCSS Total Symptom score and different symptom domains’ utility in predicting prolonged recovery. Overall, it appears that acute symptom burden and increased symptom-reporting at initial assessment are predictive of prolonged recovery (Iverson et al, 2017; Meehan et al, 2014, 2016; Schilling et al, 2020), with several authors offering varying numerical cutoffs for different symptom domains (Eagle, Womble, et al, 2020; Lau et al, 2011, 2012). Even still, several other noncognitive/symptom factors have been associated with increased risk for and prediction of prolonged recovery status, including premorbid personal or family psychiatric history, onset of depression and/or headaches following injury, mechanism of injury (e.g., car accident vs. sport concussion), time to initial clinic visit, genetic risk status (e.g., APOE ε4), and delayed removal from play (Asken et al, 2016, 2018; Eagle, Puligilla, et al, 2020; Iverson et al, 2017; Merritt & Arnett, 2016; Merritt et al, 2016; Morgan et al, 2015).…”
