Concussion care guide

A concussion / mild-TBI care guide (Amsterdam 2023 / Parachute 2024 / Ontario Living Guidelines). Red flags go to the ER first; otherwise it’s brief rest then EARLY sub-symptom-threshold activity, graduated return-to-learn and return-to-sport, and cluster-directed rehab for persistent symptoms. Enter phase, red flags and symptoms below.

Context

Phase

Acute (< 4 weeks)

Key principle

Brief relative rest (24–48 h), THEN early sub-symptom-threshold activity — prolonged strict rest is NOT recommended (Amsterdam 2023).

Notes

  • • Modern management (Amsterdam 2023 / Parachute 2024): a brief 24–48 h of relative rest, THEN early return to light sub-symptom-threshold physical and cognitive activity. Prolonged strict rest is not recommended and delays recovery.
  • • Graduated return: each step ≥24 h, symptom-limited, no same-day return to play. Return-to-learn precedes full return-to-sport, and a physician/NP must medically clear the athlete before full-contact activity.
