Migraine in China

Migraine is a prevalent and debilitating CGRP-mediated neurological disorder characterized by recurrent attacks lasting four to 72 hours with four classic symptoms, including one-sided, pulsating headaches of moderate or severe pain intensity that are associated with nausea or vomiting, and/or hypersensitivity to light (photophobia) and sound (phonophobia). The World Health Organization’s (WHO) 2015 Global Burden of Disease Study ranks migraine as the third most prevalent disease in the world [1] and the seventh highest specific cause of disability worldwide. Migraine affects approximately 9% of the adult population in China[2], comprising approximately 90 million adults. Approximately 90% of Chinese migraineurs suffer from between one to fourteen headache days per month, and approximately 10% have more than fourteen per month[3]. Approximately 24% of individuals Chinese migraineurs miss more than twenty days of work over a three-month period as a result of migraine [2]. The total indirect cost to Chinese society from lost productivity each year due to migraine is estimated to be about USD$40 billion[2]. Comorbid conditions associated with migraine include depression, anxiety and cardiovascular disease[4].
