Newly Developed Inhaler to Treat Migraine Without Medicine, says Study

While 45 per cent people experienced an effect the first time, and that number rose to 78 per cent the second time

Some migraine patients can cut down on medication or stop using it completely by using a newly developed inhaler which changes the composition of the air we breathe, results of a clinical trial say.

Migraines occur as part of a chain reaction during which the veins in the brain contract and the blood cannot therefore supply the brain with sufficient oxygen, the researchers said.

In the study, the team from the Aarhus University in Denmark examined a small group of patients who suffer from migraine with aura, which is where they experience either sensory or visual disturbances before the painful headaches begin.

The novel inhaler slightly changes the body’s own molecules.

It utilises carbon dioxide and oxygen, which are the body’s natural molecules for mobilising its own defence against migraine attacks.

“The inhaler expands the blood vessels that supply the brain with oxygen by up to seventy per cent and thereby stops the destructive chain reaction,” said Troels Johansen, from the varsity.

Johansen added that the effect of the treatment starts after a few seconds.

The results, published in the journal Cephalalgia, showed that the effect of the pain relief increased significantly with each use of the inhaler.

“The study shows some very significant physiological effects in the body,” Johansen said, adding that the team is now planning to conduct a large clinical trial that will also include migraine without aura and chronic migraine. (IANS)

According to New Study, Migraine Raises Risk of Chronic Dry Eye Disease

For men, aged 65 or above, having migraine nearly doubled the odds of dry eye disease, and risk in women of the same age was almost 2.5 times

Suffering from migraine? You could be at higher odds of having chronic dry eye disease, says a new study.

The chronic dry eye is a common disease in which natural tears fail to adequately lubricate the eyes, thus affecting its functioning and lessening a person’s quality of life.

The study showed that people with migraine had a 20 per cent higher risk of having dry eye disease, the HealthDay reported.

For men, aged 65 or above, having migraine nearly doubled the odds of dry eye disease, and risk in women of the same age was almost 2.5 times.

The association between migraine and dry eye was found to be more among the elderly, particularly for women due to hormonal changes caused by pregnancy, the use of oral contraceptives and menopause, the researchers said.

“Physicians caring for patients with a history of migraine headaches should be aware that these patients may be at risk for concurrent dry eye disease,” said Richard Davis, ophthalmologist at the University of North Carolina at Chapel Hill in the US.

For the study, the team examined 73,000 adults.

The findings, published in the journal JAMA Ophthalmology, showed 8-34 per cent of adults may be affected by dry eye disease.

Further, similar underlying inflammatory processes at the cellular level are known to play key roles in both dry eye disease and migraine.

“Inflammatory changes in dry eye disease might trigger similar events in neuromuscular tissue, leading to the development and propagation of migraine headaches,” the team noted.

In addition, rheumatoid arthritis, diabetes, thyroid problems, exposure to smoke, wind and dry climates, and long-term use of contact lenses can also lead to dry eyes, the study noted. (IANS)
