what triggers vertigo symptoms
1 Symptoms may include vertigo with one-sided ringing in the ear and hearing loss.  Vertigo can be caused by decreased blood flow to the base of the brain. A blood clot or blockage in a blood vessel in the back of the brain can cause a stroke (cerebral vascular accident or CVA).
Vertigo is most often caused by a problem in the balance centers of the inner ear called the vestibular system and causes the sensation of the room spinning. It may be associated with vomiting. Symptoms often are made worse with position changes.
