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)

Coffee lovers, please take note. Drinking three or more servings of caffeinated beverages a day increases the risk of migraine.

In a study published in the American Journal of Medicine, researchers evaluated the role of caffeinated beverages as a potential trigger of migraine.

They found that, among patients who experience episodic migraine, one to two servings of caffeinated beverages were not associated with headaches on that day, but three or more servings of caffeinated beverages may be associated with higher odds of migraine headache occurrence on that day or the following day.

“While some potential triggers – such as lack of sleep – may only increase migraine risk, the role of caffeine is particularly complex, because it may trigger an attack but may also help control symptoms, caffeine’s impact depends both on dose and on frequency,” said Elizabeth Mostofsky from Harvard University.

During the study, 98 adults with frequent episodic migraine completed electronic diaries every morning and every evening for at least six weeks.

Every day, participants reported the total servings of caffeinated coffee, tea, soda and energy drinks they consumed, as well as filled out twice daily headache reports detailing the onset, duration, intensity, and medications used for migraines since the previous diary entry.

Participants also provided detailed information about other common migraine triggers, including medication use, alcoholic beverage intake, activity levels, depressive symptoms, psychological stress, sleep patterns and menstrual cycles.

To evaluate the link between caffeinated beverage intake and migraine headache on the same day or on the following day, researchers used a self-matched analysis, comparing an individual participant’s incidence of migraines on days with caffeinated beverage intake to that same participant’s incidence of migraines on days with no caffeinated beverage intake.

The researchers further matched headache incidence by days of the week, eliminating weekend versus week day habits that may also impact migraine occurrence.

Self-matching also allowed for the variations in caffeine dose across different types of beverages and preparations.

“One serving of caffeine is typically defined as eight ounces or one cup of caffeinated coffee, six ounces of tea, a 12-ounce can of soda and a 2-ounce can of an energy drink,” Mostofsky said.

“Those servings contain anywhere from 25 to 150 milligrams of caffeine, so we cannot quantify the amount of caffeine that is associated with heightened risk of migraine. However, in this self-matched analysis over only six weeks, each participant’s choice and preparation of caffeinated beverages should be fairly consistent,” Mostofsky added. (IANS)
