Do concussed and non-concussed head trauma individuals have similar symptoms? A retrospective chart review of chronic post-concussive symptomatology

Abstract

Many head trauma patients who present with prolonged post-concussion symptoms do not meet the American Congress of Rehabilitation Medicine (ACRM) diagnostic criteria for mild traumatic brain injuries (mTBI). This population has not been extensively studied and its clinical characteristics are currently uncertain. A retrospective chart review was conducted to explore the symptomatic differences between mTBI and non-mTBI head trauma patients presenting at a concussion clinic with chronic post-concussion symptoms (PCSx). Patient information was extracted from 161 charts, of which 128 subjects met the ACRM criteria for mTBI (ACRM + PCSx), while 33 did not (non-ACRM + PCSx). These two groups were compared for demographic variables and symptomology. This study found that 20.5% of subjects presenting with chronic post-concussion symptoms do not meet ACRM criteria. No symptom-specific differences were found between the two populations in any of the categories tested. These results show that chronic post-concussion symptoms are similar in both mTBI and non-mTBI head trauma patients in the general population, suggesting a need for further research focusing on this group.
