title: Prognostic Markers for Poor Recovery After Mild Traumatic Brain Injury in Older Adults: A Pilot Cohort Study.
abstract: 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.
  
  
  
  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.
