Light Therapy May Prevent Migraine

January 02, 2008 | 6,347 views

Treating patients with bright light therapy may be useful in preventing migraine headaches.

The possible effectiveness of the therapy, which has been used to treat seasonal affective disorder, insomnia and eating disorders, has surprised some researchers since people with migraines generally try to avoid bright lights during attacks.

The new findings were presented in London last week at the 12th Migraine Trust International Symposium. Dr. L. Pinessi and colleagues at Torino University, Italy, administered 30 minutes of bright light therapy (2500 lux) on alternate days to nine patients.

Compared to the pretreatment phase, seven out of nine patients reported a reduction in migraine attacks. Dr. Pinessi believes that bright light may elevate brain concentrations of several neurotransmitters, including serotonin.

Impaired serotonin metabolism has been observed in some patients with migraine.

Dr. Mercola's Comment:

An interesting alternative to consider for migraine treatment.
