Is Migraine Linked to Ear Disorders?

The researchers hypothesized that these abnormalities could be a result of compromised blood supply to the auditory system due to the migraine attacks

migraine is a risk factor for sudden sensorineural hearing loss -- characterized by rapid loss of hearing in one or both ears, which may occur immediately or over the course of several days.

People with chronic migraines may be at an increased risk of developing tinnitus — feeling of ringing in the ears — and other inner ear disorders, than those without the severe headache condition, says a study.

The researchers found that the risk of cochlear disorders, especially for tinnitus, was found to be significantly higher among patients with a history of migraines.

The study may support the presence and/or concept of “cochlear migraine”, said researchers including Juen-Haur Hwang from Dalin Tzu Chi Hospital, Taiwan.

Cochlear disorders are a condition that affect “snail shell shaped” part of the inner ear which receives sound in the form of vibrations and includes tinnitus, sensorineural hearing impairment, and/or sudden deafness.

The researchers found that the risk of cochlear disorders, especially for tinnitus, was found to be significantly higher among patients with a history of migraines.

For the study, published in the journal JAMA Otolaryngology – Head and Neck Surgery, the team included data from 1,056 patients with a history of migraines and 4,224 controls.

The cumulative incidence of cochlear disorders in the migraine cohort was significantly higher by 12.2 per cent than that in the matched non-migraine cohort of nearly six per cent.

Subgroup analysis showed that compared with the non-migraine cohort, the adjusted hazard ratios in the migraine cohort were 3.30 for tinnitus, 1.03 for sensorineural hearing impairment, and 1.22 for sudden deafness, suggesting that people with migraine history are more susceptible to developing tinnitus than any other form of cochlear disorders.

High BP Medicine May Help Treat Migraine

A medication originally used to treat high blood pressure may help you from migraine pain attacks.
Candesartan – a drug used to treat high blood pressure – is just as effective as the commonly prescribed propranolol for migraine sufferers, according to a study.

The researchers also found that candesartan may work for patients who get no relief from propranolol.

“This gives doctors more possibilities and we can help more people,” said professor Lars Jacob Stovner, from Norwegian University of Science and Technology (NTNU).

“Candesartan is already in use by several doctors as a migraine preventive medicine but our follow-up study provides the proof that the drug actually works as a treatment,” said the researchers.

The NTNU study was a triple blind test, which means that neither patients nor doctors nor those who analysed the results knew whether the patients had been given placebo or real medicine, Stovner said.

Researchers tested both candesartan and propranolol in 72 patients.

These patients were normally affected by migraine attacks at least twice every month.

The patients used each treatment (candesartan, propranolol or placebo) for 12 weeks.

More than 20 percent of migraine patients reported that they feel better even when they are given a placebo.

But blind tests show that candesartan works preventively for another 20 to 30 percent of patients.

“The hope is now that candesartan will be even more commonly prescribed,” said Stovner.
