Migraine could be a risk factor for stroke. The probability of stroke increases if the patient also has hypertension. Those 40-49 years old who suffered from migraines and hypertension had a 5% more chance of getting a stroke than those with hypertension alone. This study was done in Italy and included almost 3,000 subjects. The findings were presented in 2011 at the European Meeting on Hypertension 2011 by Dr. Enrico Agabiti-Rosei. He concluded that further studies need to be done on whether early migraine treatment can reduce the risk of stroke.
