Study: Common triggers may not set off migraines

COPENHAGEN, Denmark -- People who experience migraines with aura are often told to avoid common triggers, like bright lights and vigorous exercise. However, a new study suggests that may not be necessary.

Researchers at the University of Copenhagen in Denmark studied nearly 30 people who had experienced migraine with aura triggered by exercise or bright, flickering lights.

They exposed each participant to the triggers again and found no one developed a migraine after exposure to bright light alone.

One in 10 had a migraine with aura after exercising and seeing bright lights, while another 10 percent developed a migraine without aura.

Researchers say this study suggests if a trigger has not led to a migraine in three months, patients no longer have to avoid it.

When aura is experienced with a migraine, patients report seeing wavy lines or flashing lights.

This study was published in the journal Neurology.
