The vestibular system is the inner ear system that processes information to control balance and eye movements. When this system becomes disrupted you may feel sensations of dizziness, nausea, vomiting, vertigo, imbalance, and visual disturbances, etc.
BPPV (benign paroxysmal positional vertigo) is a common condition that generally occurs in individuals >65 years old. Symptoms associated with this condition include dizziness, nausea, vomiting, and vertigo which is the illusion that objects are spinning while you remain stationary. BPPV occurs when otoconia (crystals) are displaced from their normal habitat and reside in the incorrect portion of the ear. When this occurs one may experience symptoms when moving their head in certain positions such as laying down in bed or turning over in bed. Physical therapy can help resolve these symptoms by using maneuvers to return the otoconia back to their normal habitat.
Vestibular Neuritis is another vestibular condition that produces symptoms such as dizziness, vertigo, pressure, nausea, vomiting, imbalance, etc and is caused by a viral infection. Vestibular neuritis occurs when the nerve in the inner ear, called the vestibulocochlear nerve, is inflamed or damaged. This then disrupts the way the brain processes information of head position and balance. Physical therapy can help retrain the brain to adapt to these changes that you may be experiencing.
Consult with your physical therapist if you are experiencing any of these symptoms in order to receive the correct treatment!
