Close to one billion people suffer from migraine all across the world. While the exact cause of the neurological disease is unknown to the world of science, a recent study links financial stress to risk of developing the debilitating headache. According to a team of experts from Hungary, those with a certain gene variant may end up being more susceptible to migraine. "Our results shed light on one specific mechanism that may contribute to migraine. What it does mean is that for many people, the stress caused by financial worries can physically affect you. What we need to do now is to see if other circadian gene variants in association with different stress factors cause the same effect," noted Daniel Baksa from the Semmelweis University in Budapest, Hungary.Although no direct correlation was found between financial stress in people and incidents of migraine, it was noted that people with gene variants who also battled financial stress were at least 20% more likely to suffer from migraine.
