Concussions are becoming more common again as people return to regular activities following COVID-19 lockdowns and restrictions, when concussion rates declined. Each year, about one per cent of Canadians sustain concussions, amounting to some 400,000 concussions in Canada alone. Worldwide, that number grows to over 40 million annually.
Concussion is a critical public health concern. Up to 30 per cent of children and adults will have persistent problems after concussion that lower their quality of life and hinder their return to work, sport, school and other activities.
