New research indicates people who suffer from migraine with auras may not have to avoid certain triggers long-term.
Aura refers symptoms experience shortly before the headache begins. These symptoms include, blind spots or scotomas, blindness in half of your visual field in one or both eyes, seeing zigzag patterns, seeing flashing lights, feeling prickling skin, weakness and hallucinations.
Doctors often tell people who suffer from migraine with auras to avoid common triggers like bright lights and vigorous exercise, but a recent study suggests that might not be necessary.
Researchers at the University of Copenhagen in Denmark studied 30 people who experienced migraine with aura triggered by exercise or bright, flickering light. They exposed each patient to the triggers again and found none developed a migraine after exposure to bright light alone. One in 10 had a migraine with aura after exercising and seeing bright lights.
Researchers say the study suggests if a trigger has not led to a migraine in three months. patients no longer need to avoid it.
