A traumatic brain injury (TBI) can be generally defined as any injury to the head which damages the brain. A TBI can vary in severity and symptoms. If your child has suffered a TBI, you have likely noticed physical symptoms like dizziness and decreased coordination. TBIs also affect cognition and communication. TBIs are best treated by a team of professionals, which will likely include doctors, speech-language pathologists (SLPs), physical therapists, occupational therapists, and neuropsychologists.
