Have you ever suffered a concussion? Has any one you know or love ever suffered a concussion? CN! nonprofit family member Concussion Alliance invites anyone recovering from a concussion or friends and family of those who have had a concussion to join their Facebook group. This group is intended to help people navigate their way to recovery and create a community where people suffering from concussions can be together. Concussion Alliance was founded by concussion patients and families. We are proud to have this resource in the CN! nonprofit family.
