Understanding and addressing unmet need in chronic migraine

  • It is estimated that 190,000 migraine attacks are experienced every day in the UK5
  • Migraine affects approximately 23.3% of adults in the UK, with a higher prevalence in females than in males6,7
  • As many as 86 million workdays could be lost annually in the UK due to migraine-related absenteeism and presenteeism6
  • Chronic migraine is a debilitating disease, affecting 1.4-2.2% of adults worldwide8

CHRONIC MIGRAINE IS A COMPLEX NEUROLOGICAL DISEASE REQUIRING APPROPRIATE EFFECTIVE MANAGEMENT – INCLUDING TREATMENT OR REFERRALS TO IMPROVE PATIENT OUTCOMES2,9,10

Chronic migraine is defined by the International Headache Society (IHS) as:9


Chronic migraine is a complex and fluctuating disease that debilitates patients when it is not treated effectively11,12

Patients with chronic migraine exhibit large variations in the frequency of their migraines12

Adapted from Serrano D et al, 201712

Over 70% of patients experience variation in the frequency of their headaches12

Associated with many comorbidities, including anxiety, depression and sleep disorders.11,13

Common symptoms of migraine

Migraine is a complex condition with a wide variety of symptoms.9 It can be classified as migraine without aura, characterised by headache with specific symptoms and features, or migraine with aura, characterised by transient focal neurological symptoms that typically precede and/or accompany the headache.9 Some patients also experience a prodromal and a postdromal phase.9

A small proportion (<10%) of women with migraine have attacks, typically without aura, associated with their menstrual cycle.9 Attacks occurring during menstruation are usually longer and accompanied by more severe nausea than those occurring at other times of the menstrual cycle.9


Chronic migraine is a complex neurological disease requiring appropriate effective management - including treatment or referrals to improve patient outcomes2,9,10

BOTOX® (botulinum toxin type A) is indicated for the prophylaxis of headaches in adults with chronic migraine (headaches on at least 15 days per month of which at least 8 days are with migraine).16
