According to the Migraine Trust, migraine most commonly affects those aged between 35 and 45 years, but is not exclusive to this age group. Many people have their first experience of the condition at puberty, and around four per cent of both boys and girls are affected before this stage. As children get older there is a predominance among girls, which remains – three times as many women as men are migraine sufferers – and hormones are thought to cause this discrepancy.

Keeping a headache diary can help identify patterns and possible triggers, as well as record the effectiveness of any medication that is being taken. Important details to record are the date and time of day of the attack, any warning signs or symptoms, anything used to try and relieve symptoms, and when the attack ended. There are templates for this available online, but logging it on a mobile phone may be more convenient and quicker for many.
