Green Light Improves, Reduces Photophobia and Migraine Severity


Light sensitivity is a frequent symptom of migraine, but according to a study done earlier this year, a certain kind of light may reduce migraines.

A study done by researchers at Beth Israel Deaconess Medical Center (BIDMC) in Boston has found that exposing migraine sufferers to a narrow band of green light can reduce light sensitivity, known as photophobia, and headache severity. The study was published in the May 2016 edition of Brain. Continue Reading

Heightened Brain Connectivity May Explain Light and Sound Sensitivity in Migraineurs

Light Sensitivity

Many migraineurs suffer from light and sound sensitivity, and researchers recently determined they have heightened connectivity between specific areas of the brain. This finding may help in the development of migraine treatments, said lead author Amy R. Tso, MD, of the University of California at San Francisco.

In a study of 15 patients with migraine without aura, researchers used a functional MRI to evaluate the areas of the brain involved in processing visual and auditory information. They found that there was increased connectivity between primary visual and auditory cortices, where visual and auditory information is processed; the pons, which serves as a communication center in the brain; and the anterior insula, a region involved in coordinating responses to matters of emotional importance.

Chronic Migraine and Abnormal Sense of Smell Linked



Patients with chronic migraine are often hypersensitive to stimuli, including light, sound, and odors. In fact, some researchers believe the aversion to odors, osmophobia, is particularly helpful in a differentiating migraine from other headache disorders. Now, new research suggests that patients with chronic migraine (CM) do not experience a significant change in their sense of smell between migrainous and non-migrainous periods, but they appear more likely to have an abnormal sense of smell at baseline compared to their peers who do not experience migraine.
