I might be able to help the noble Baroness in some way. It is estimated that 190,000 migraine attacks occur every day in the UK. Over three-quarters of people who get migraine have at least one attack each month. Chronic migraine—it is a justified question—when a person gets a headache on 15 or more days a month, eight of them migraine, is less common but affects about two in 100 people.
