Summary. 1  Generally, most dizziness is caused by problems of the inner ear and is treatable. 2  Common causes of inner ear dizziness include benign paroxysmal positional vertigo (BPPV), migraine and inflammation of the inner ear balance apparatus called vestibular neuritis.
Dizziness may be caused by any disturbance in the inner ear, the balance nerve or its central connections. This can be due to a disturbance in circulation, fluid pressure or metabolism, infections, neuritis, drugs, injury or tumors. An extensive evaluation is required at times to determine the cause of dizziness.
