I am a board-certified clinical neuropsychologist. I have worked in hospitals, group private practice settings, and am now a sole private practitioner conducting forensic work. My clinical background has made me competent in assessing individuals with all kinds of neurological presentations. I have experience with epilepsy, traumatic brain injury, dementia, movement disorders, and stroke as well as pediatric/developmental issues. I currently average at seeing several post-concussive syndrome patients per year. I have been reviewing forensic cases for the past approximate two years and have done depositions within a city school system. As per your question regarding neuropsychological sequelae of a traumatic brain injury, it would certainly be dependent upon the type and severity of the brain injury. Someone with a loss of consciousness following a motor vehicle accident would be expected to be at greater risk for decreased attention/concentration, processing speed, and memory functioning primarily with psychological manifestations of depression, irritability possible as well. The severity of the symptoms expected in the 2 years following a concussion would be dependent upon the severity of the injury. Neurological problems including frequent headache, dizziness, vomiting/nausea would be likely in the acute phase but not necessarily be expected in a traumatic brain injury after time has passed.
