I believe so, yes - but that's just my undiagnosed opinion. It's actually a relief to think that some of my learning problems - mostly memory, and social behavior and lack of discriminating thinking - might have been caused by a concussion, rather than feeling alienated because I was "weird". Your daughter can probably be monitored by you and her doctors closely enough to provide her with ways to manage the changes through therapies and coping tools that didn't exist when I was little.
