Tension Headache Causes
Experts continue to debate the causes and even the name of tension headaches. Over the years, as different theories emerged about the origins of this type of headache, it was known by names such as muscle contraction headache, psychogenic headache, depressive headache, essential headache and ordinary headache.
The exact cause or causes of tension headache are unknown. Until a few years ago, many researchers believed that the pain of tension headache stemmed from muscle contraction in the face, neck and scalp, perhaps as a result of heightened emotions, tension or stress. But many researchers have questioned this idea.
More recent research discredits this theory. Studies using a test called an electromyogram, which records the electric currents generated by muscle activity, haven’t detected increased muscle tension in people diagnosed with tension headache. In addition, people with migraine have as much muscle tension as do people with a tension headache, if not more.
As a result, The International Headache Society uses the term “tension-type headache” instead of “tension headache,” calling attention to the fact that muscle tension may not be the main cause of this kind of head pain.
