A new research has shown those who suffer chronic migraine are generally not so healthy and wealthy. They are also found to be more depressed than those who suffer episodic migraine.
The results are based on the study of 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.
All participants were already part of the American Migraine Prevalence and Prevention (AMPP) study, a long term US population based study of 24,000 headache sufferers, which has included regular surveys since 2004.
The researchers analysed data collected in the 2005 survey on socioeconomic circumstances and other health problems.
They found that those with chronic migraine had significantly lower levels of household income, were less likely to be working full time, and were almost twice as likely to have a job related disability than their peers with episodic migraine.
They were twice as likely to be depressed, anxious, and experiencing chronic pain. And they were significantly more likely to have other serious health problems.
These included asthma, bronchitis, and chronic obstructive pulmonary disease (COPD), high blood pressure, diabetes, high cholesterol and obesity.
They were also around 40 percent more likely to have heart disease and angina and 70 percent more likely to have had a stroke.
The research point out that chronic migraine "can be an especially disabling and burdensome condition."
The study has been published in the Journal of Neurology Neurosurgery and Psychiatry. (ANI)
