Headache Overview

Everyone is familiar with a simple headache, which is annoying but disappears after a few hours. There are many other types of headache (e.g. tension headache, cluster headaches, migraine) and there are many different causes of headache.

Causes of headache range from simple conditions that are mostly harmless (e.g. common headache, tension headache, etc.) to some more serious causes of headache (e.g. migraine, fever), up to some very severe and life-threatening possible diseases (e.g. stroke, concussion, brain hemorrhage, brain tumor, etc.).
