The type of headache can be determined from the headache location, nature, duration and possible accompanying signs. The doctor can examine whether there is tension in the neck and shoulders, and the vision is normal. In rare cases where there is suspicion of a serious underlying disease of the brain, a CT or MRI scan is relevant (see: Graph of the brain).
