Headache Causes Difficulty Tuning out Visuals

A recent study from researchers from Scotland’s Glasgow Caledonian University has come out with implications for headache sufferers. The research suggests migraine sufferers even when they do not have a headache may process visual cues better in an environment with few visual distractions.

The researchers asked migraine sufferers to pick out a small disk of light with visual noise was present which severed as a visual distraction. Without the visual noise, people prone to migraine could identify the light disk about as well as the control group. When the noise was added, migraine sufferers performed significantly worse.

The study demonstrated migraine sufferers with auras were the actually the most affected by the addition of visual noise.

This research has practical implications for those who suffer from headache and migraine. It may thus be best to avoid environments with a lot of visual distractions. This can included several TV and computer screens along with loud noises.

Gene Linked to Increased Heart Disease in Migraine Women

Heart disease is the leading cause of death and stroke is the third leading cause of death in the United States.

Women who experience migraine with aura appear to be at an increased risk of heart disease and stroke if they have a certain gene.

For the study, researchers followed 25,001 Caucasian women for the occurrence of cardiovascular disease, including heart attacks and ischemic stroke. About 18 percent of the women in the study had a history of migraine while 40 percent of those with active migraine reported migraine with aura. Migraine with aura can be described as neurological symptoms that usually last for about 30 minutes and most often lead to visual disturbances. The women were also tested for a certain gene variant in the methyleneterahydrofolate reductase gene.

During a 12-year follow-up period, 625 cardiovascular disease events occurred.

The study found that women who had both the gene variant and migraine with aura had more than three times the risk of cardiovascular disease, which was driven by four times the risk for stroke compared with women who did not have the gene variant and no history of migraine.

“This gene by itself does not appear to increase the risk for overall and for specific cardiovascular disease, but rather this research suggests a possible connection between the gene variant and migraine with aura. While it is too early to start testing young women with migraine with aura for this gene variant, more focused research will help us to understand these complex links and will help us to potentially develop preventative strategies,” said study author Tobias Kurth, MD, ScD.

“Doctors should try to reduce heart disease risk factors and advise young women who experience migraine with aura not to smoke and to consider birth control pill alternatives as these increase the risk of ischemic vascular problems,” said Kurth.
