That memory of hers never did come back. Almost complete memory loss of all events and people prior to the concussion. That said, given what I know others endure ... we can't complain. Very little problems with headaches ... and she is now completely cleared for all activities. In fact she got straight A's in school for the last quarter, so cognitive abilities still super. Turns out, too, that fifth graders (at least our fifth grader) doesn't care that she can't remember anything of her life prior to the concussion!
