Peripheral Artery Disease

Peripheral arterial disease refers to a circulatory impairment that causes narrow blood vessels in the extremities resulting in decreased blood flow. The most common cause of this condition is atherosclerosis, where fat and plaque builds up in the arteries. Most people will have a variety of symptoms, mostly occurring in their legs such as pain while walking, numbness, cool extremities and a pale or bluish discoloration. 

The MAST study’s migraine group was at least twice as likely to experience peripheral artery disease.1 The study also found that those who had 5-9 monthly headache days were at an increased risk for peripheral artery disease compared to those who had 1-4 headache days per month.1
