Concussion Care Pathway

Date of last update: May, 2024


Clinical Cornerstone:

  • The majority of traumatic brain injuries are considered “mild”. Nearly one in two people will experience a mild traumatic brain injury in their lifetime. Concussion is considered a concussion.

  • Diagnosing a concussion requires a patient-centered approach that integrates physical and psychological aspects of the patient’s symptoms.

  • Diagnosis may be complicated by comorbid conditions that mimic concussion symptoms (e.g. anxiety, migraine, etc.). Clinical reasoning is needed to increase confidence in a diagnosis of concussion, and to decrease confidence that more serious conditions, more serious TBI, or conditions with similar symptoms are present. A comprehensive diagnostic strategy integrates clinical findings with patient narratives and risk factor evaluations for a fulsome understanding of the patient's condition.


  • One or more conditions need to be met for the diagnosis of concussion once a plausible mechanism of injury has been established and suspicion for other causes of the patient’s symptoms has decreased

    • one or more clinical signs; altered mental status, loss of consciousness (<30 minutes), amnesia (<24 hours), neurological signs (seizure, coordination, etc.).

    • two or more new or worsened clinical symptoms; subjective alteration of mental status (feeling dazed or confused), physical symptoms (headache, nausea, dizzy or sensitive to light/sound), cognitive symptoms (feeling run down, fatigue or foggy/processing-speed), emotional symptoms (lability, impulsivity).

    • unambiguous imaging evidence of neurotrauma.

  • Other common symptoms include:

    • sleep disturbance

    • visual disturbance

    • hearing difficulties, tinnitus

    • difficulties with memory/retrograde amnesia/anterograde amnesia

    • difficulties with focus/concentration

    • difficulties with judgement/executive-function

    • depression or anxiety

    • loss or decreased levels of consciousness <30 minutes

Documentation: Record all findings in the patient record.
