To identify prognostic markers associated with poor recovery from mild traumatic brain injury (MTBI) in older adults.


Three Ontario emergency departments.


Forty-nine participants aged 65 years and older that visited an emergency department for MTBI.


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.


Markers potentially associated with poor recovery included reporting worse health 1 year before the injury, poor expectations for recovery, depression, and fatigue.


Recovery after MTBI in older adults may be associated more with psychosocial than with biomedical or injury-related factors.
