Vestibular dysfunction is one of the top complaints that patients report after a concussion/mTBI. There are several possible causes for dizziness, and it must be assessed appropriately to rule out other organic causes such as anxiety and medication side effects.
Injuries to the cranial nerves (vestibulocochlear, optic, and oculomotor nerves) and cerebellum are possible causes that need further evaluation with a specialist based on a neurological exam and on your patient's report from the Dizziness Handicap Inventory questionnaire.
A referral to vestibular rehabilitation or physical therapy, neuro-optometry, and/or neuro-otology may be warranted, especially if symptoms change or get worse. If a patient presents with neck pain or stiffness along with dizziness, this may indicate a neuromuscular injury and would require an evaluation with physiatry, sports medicine or orthopedics, and/or physical therapy. Once the initial evaluation is complete, a service member or veteran may be able to complete therapy from home, but encourage them to stay within their symptom tolerance.
