What Is Secondary BPPV?

I believe secondary BPPV is BPPV caused by another vestibular dysfunction. For instance, neuritis may cause swelling around the nerve, which could push on arteries that supply blood to the otoliths. This could cause the system to become necrotic and now the person is more likely to get BPPV. Meniere's slowly destroys the otoliths and the rest of the inner ear causing one to be more likely to develop BPPV. A person who has TIAs may not only have poor circulation to their brain, but also to the inner ear...this could be an example of secondary BPPV. In this last case, BPPV would not really be so benign because it's cause is actually life threatening.
