A traumatic brain injury (TBI) is caused by a bump, blow, or jolt to the head or a penetrating head injury that disrupts the normal function of the brain" (CDC). This type of injury can result in various symptoms, including those assessed and treated by a neuropsychologist: cognitive, emotional, mood, and personality changes. If you are experiencing persistent symptoms following a TBI, a neuropsychological evaluation may be appropriate. Please see the FAQs section of this website for what a neuropsychological evaluation entails. A great resource for patients and families is the Traumatic Brain Injury Survival Guide.
