Chronic migraine sufferers tend to be in poorer general health and more depressed than those with episodic migraine, according to US research.
The findings are based on almost 12,000 adults with episodic – a severe headache on up to 14 days of the month – or chronic migraine – headache on 15 or more days of the month.
Those with chronic migraine were twice as likely to be depressed, anxious, and experiencing chronic pain. They were also significantly more likely to have other serious health problems, such as asthma.
Writing online in the Journal of Neurology Neurosurgery and Psychiatry, the authors said chronic migraine “can be an especially disabling and burdensome condition”.
