What Can Trigger Vertigo?
Vertigo is the sensation of spinning or rocking, even when someone is at rest. Vertigo may be caused by a problem in the brain or spinal cord or a problem within in the inner ear. Head injuries, certain medications, and female gender are associated with a higher risk of vertigo. Medical history, a physical exam, and sometimes an MRI or CT scan are required to diagnose vertigo. The treatment of vertigo may include medication, special exercises to reposition loose crystals in the inner ear, or exercises designed to help the patient re-establish a sense of equilibrium. Controlling risk factors for stroke (blood pressure, weight, cholesterol, and blood glucose) may decrease the risk of developing vertigo.
