| Vascular constriction | Some evidence suggests that constricted blood vessels in the inner ear may reduce blood flow, similar to mechanisms proposed in migraine |
| Viral infections | Previous viral infections may damage the endolymphatic sac or inner ear structures |
| Allergies | Allergic reactions may trigger inflammatory responses affecting inner ear fluid balance |
| Autoimmune reactions | Some researchers believe autoimmune mechanisms may contribute to disease development |
| Genetic variations | There appears to be a hereditary component in some families, though most cases appear sporadic |
