OBJECTIVE: To identify prognostic markers associated with poor recovery from mild
traumatic brain injury (MTBI) in older adults.
SETTING: Three Ontario emergency departments.
PARTICIPANTS: Forty-nine participants aged 65 years and older that visited an
emergency department for MTBI.
DESIGN: Pilot prospective cohort study.
MAIN MEASURES: Recovery from MTBI determined using the Rivermead Postconcussion
symptom Questionnaire, the Glasgow Outcomes Scale-Extended, physical and mental
health functioning (SF-12), and a single question on self-rated recovery assessed
by telephone shortly after emergency department visit (baseline) and again 6
months later. Predictors were measured at baseline.
RESULTS: Markers potentially associated with poor recovery included reporting
worse health 1 year before the injury, poor expectations for recovery,
depression, and fatigue.
CONCLUSION: Recovery after MTBI in older adults may be associated more with
psychosocial than with biomedical or injury-related factors.
