REACTIONS is the first ever measure for documenting post-concussive symptoms in children under 5 years who sustain concussion or TBI. The aim of the project is to validate an observational inventory of TBI manifestations and symptoms.


  • Age: 1 month to 8 years
  • 79 children with TBI


  • Recruitment at emergency departments
  • Parent questionnaires


  • CHU Sainte-Justine
  • Montreal Children’s Hospital

Key Results

The REACTIONS inventory is useful and helps identify post-concussion symptoms in young children.

We are currently using this inventory of post-concussion observations in the KOALA project. Further validation studies with the REACTIONS inventory and translations and adaptations to other languages are ongoing.
