Here is an excerpt from Dr. Carol Foster’s website. (She is a neuro-otologist in Colorado) I bolded for emphasis a few sentences below:
"A large percentage of people with Meniere’s disease also have migraine, and this is particularly true for those with a family history of Meniere’s disease. Migraine is genetically mediated (see Migraine and dizziness) and rarely causes permanent damage to the ear. However, in some migraine cases a typical Meniere’s syndrome develops. One autopsy specimen on a migraine patient with Meniere’s disease showed that endolymphatic hydrops was present in the affected ear . This suggests that the combination of hydrops with migraine, and not migraine alone, can cause Meniere attacks. ** Sleep apnea, a snoring problem with pauses in breathing during the night, is strongly associated with Meniere’s disease. This disease, like migraine, is a vascular risk factor. Many other vascular risk factors, such as autoimmune disease, hypertension, and diabetes, have also been associated with Meniere attacks. It is probably a combination of hydrops with vascular risk factors of many different types that set off these attacks.
**
Treatment is aimed at either reducing the hydrops, reducing vascular risk factors, or accelerating the process of vestibular damage so that vertigo spells cease sooner. No treatment has been shown to stop the progression of the hearing loss. Patients suspected of having the migraine-associated type may be managed with migraine prophylactic medications. A low-salt (reduced sodium) diet has been used for decades and seems helpful in many sufferers. Diuretic medications help remove sodium from the body, and are felt to be useful in reducing the fluid pressure in the ears associated with endolymphatic hydrops. They also help control hypertension, a vascular risk factor. When symptoms flare, steroids may be given by mouth or injected behind the eardrum to calm the process**. Patients with sleep apnea often improve once their condition is treated with CPAP, an assisted breathing machine. "**
