Tension Headaches
The annual prevalence of tension headaches is 74%, much higher than for any other type of headache.
- Approximately 20% to 30% of the population experience more than one tension headache per month.
- Tension headaches are 40% more frequent in women compared to men.
These criteria, established by the International Headache Society (IHS), are used to evaluate whether a person is suffering from a tension-type headache:
- The headaches must have at least two of the following pain characteristics:
- pressing (nonpulsating) quality
- mild or moderate intensity (may inhibit, but does not prohibit, activities)
- located on both sides of the head (bilateral)
- no aggravation of pain caused by routine physical activity
- The individual must not be experiencing nausea or vomiting. He or she may experience unusual sensitivity to light or sound, but not both.
- The headache is a primary headache, and no evidence of secondary headache is suspected.
Tension headaches are divided into four categories:
- Frequent episodic tension-type headaches, infrequent episodic tension-type headaches, chronic tension-type headaches, and probable tension-type headaches differ in frequency and duration.
- Probable tension-type headaches are separated into three subcategories, two of which fulfill all but one of the above criteria.
