New study finds link between smoking and stroke in migraine patients. The study was published in the journal of the American Academy of Neurology. Researchers of the University of Miami and Columbia University were supported by the National Institute of Neurological Disorders and Stroke.
Among smokers, migraine was associated with a 3-fold increased risk of stroke
Among nonsmokers, migraine was not associated with an increased stroke risk at all.
“Taken together, we suspect that a synergic action may occur between vascular changes of migraine and smoking as an effect modifier,” says the study’s authors.
“Our findings may provide more evidence as to why quitting smoking is important for people who experience migraine”
