Migraineurs Find it Difficult to Tune Out Visual Stimuli

According to research published in the April edition of the journal Investigative Ophthalmology & Visual Science, it is harder for migraineurs to ignore visual stimuli than it is for people who do not experience migraines. Even when they are not experiencing migraine attacks, migraine sufferers find it harder than non-migraineurs to tune out visual noise. The study's lead researcher said most people can tune out less important stimuli in order to focus on items of particular interest. For some reason this is harder for migraineurs.
"Migraineurs may be at a disadvantage when searching for details, especially in cluttered environments."
Some researchers believe the nerve cells in the brains of migraineurs are especially excitable. When they become stimulated by exposure to certain triggers, a migraine attack develops. This research seems to provide a logical explanation for why computer screens, televisions, strobe lights and other flickering, dramatic visuals are migraine triggers for many people. This would also explain why it is so particularly soothing to retreat to a dark room when you are experiencing a migraine attack.
