Headache disorder is a broad term, which includes various nervous system conditions, which bring about painful symptoms in your head. It consists of both migraine and headaches. Headaches are common, and people do experience them at least once in a lifetime. Following a WHO report, it was found that approximately 50% of adults worldwide experience headache disorders.

Difference between migraine and headache
At times, it is not easy to know the difference between a migraine attack and a headache. Let us find out the basis of distinction.  

Defining them

• Headache
  It is an unpleasant pain in your head, which may lead to aching and pressure. The pain could be severe or mild and is present on both sides of the head. A few areas where you experience headaches include your forehead, back of the neck, and the temples. It will generally last anytime from half-hour to a whole week.

• Migraine
  It is a type of headache, which can lead to pain or other symptoms. If someone has a migraine, they might experience recurring attacks or episodes. Headache is only one of the symptoms of migraine. Typically, a migraine attack can last anytime between a few hours to some days. Though migraine attacks develop only on one side of the head, the pain is experienced on both sides.

Causes

  There are a few factors, which might induce a headache. These include:
