Preliminary Examinations of Concussion in Older Adults

Abstract

Abstract Purpose This study sought to investigate whether concussion in older adults improves through evaluating their performance on the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) and Vestibular/Ocular-Motor Screen (VOMS) across visits and to describe and better characterize concussion in this at-risk population. Methods We conducted a retrospective review of medical records for 69 older adult patients (40 females, 29 males) that presented to a concussion specialty clinic. Participants averaged 64.71 (SD=4.1) years in age and presented within 6-998 days of injury (SD=170.9). Demographics and clinical data were recorded at intake through last appointment. Descriptive analysis, including frequencies, means, and standard deviations were performed as well as paired T-test to compare mean scores for first and last visit. Statistical significance was determined by two-sided p-values <.05. Results Twenty out of 69 participants (29%) reported a previous concussion. Concussion symptom severity scores at participants’ first clinic visit averaged 56.19 (SD=26.56) compare with 39.51 (SD=25.53) at their final clinic visit. When comparing ImPACT data, all scores improved comparatively from Visit 1 to Last Visit (P values =0.000-0.014); all VOMS total scores improved as well (P =0.00-0.047). The most frequent primary profile among participants was Vestibular (31.9%). Conclusion Older adults diagnosed with concussion showed improvement on ImPACT scores and their symptom severity scores decreased. The most frequent primary concussion profile at initial visit was Vestibular. Further research with this at-risk population is needed.
