Sylvie was on a scooter in Amsterdam in May 2017, she got into an accident, but not falling or hitting her head, she thought it was only her ankle. From originally thinking her new, strange symptoms would only last a few days, to going from The Netherlands to America for treatment and years spent looking for the important social support of a community, in the fall of 2020, three and a half years after the seemingly innocuous accident Sylvie started The Concussion Community. The Concussion Community consists of an Instagram page, a Facebook group, and a platform with live group classes by concussion experts and a private community.
