A2. Tension-type headache (alternative criteria)

The following alternative criteria may be applied to A2.1 Infrequent episodic tension-type headache, A2.2 Frequent episodic tension-type headache and A2.3 Chronic tension-type headache. They define a core syndrome of tension-type headache. In other words these criteria are very specific but have low sensitivity.

Alternative diagnostic criteria:
    1. Episodes, or headache, fulfilling criterion A for [whichever of 2.1 Infrequent episodic tension-type headache, 2.2 Frequent episodic tension-type headache or 2.3 Chronic tension-type headache] and criteria B-D below
    2. Episodes, or headache, fulfil criterion B for [whichever of 2.1 Infrequent episodic tension-type headache, 2.2 Frequent episodic tension-type headache or 2.3 Chronic tension-type headache]
    3. Headache has at least three of the following four characteristics:
      1. bilateral location
      2. pressing/tightening (non-pulsating) quality
      3. mild or moderate intensity
      4. not aggravated by routine physical activity such as walking or climbing stairs
    4. No nausea, vomiting, photophobia or phonophobia
    5. Not better accounted for by another ICHD-3 diagnosis.
