Insomnia is a sleep condition that occurs when someone experiences difficulty falling asleep or staying asleep, or has a combination of both. This results in daytime fatigue, irritability and memory impairment. Some people may experience acute insomnia which occurs for less than a few weeks compared to chronic insomnia which occurs for greater than three nights a week for three months or longer. It is likely that migraine and insomnia have a bidirectional relationship. Insomnia is a risk factor for migraine onset, pain intensity and chronification and those with migraine are at increased risk of developing insomnia.1

A study found a higher prevalence of insomnia in people with migraine (25.9%) compared to those without migraine (15.1%).1
