Tia< Mark gives excellent advice. It is hard to tell from so short a post what advice to give. What treatments or diagnosis has your daughter had so far. Are there any other symptoms that are present. Multiple symptoms are a hallmark of head injury. Think memory, sleep irregularities, mood swings, anger issues, dizziness... Maybe it is time for you and your daughter to investigate the many implications of head trauma and its long term impacts. Is your daughter even interested in hearing some of this info. It can be frightening and overwhelming but try to remember worst case scenarios get the publication. Still if what you say is an indication of her health. Maybe a adjustment to her physical activities is in order.
