Broad asks us to consider a headache.
Migraine is considered a unilateral headache though several patients exhibit bilateral pain.
NH has provisionally been considered an epicranial headache, the pain's origin being in both internal and external layers of skull and scalp, including epicranial nerves and arteries, but no lesion has yet been found to support this hypothesis.
HC is considered a predominantly female headache [5, 7, 10] and mean age at symptoms onset is around 40 years [5, 7, 11, 12].
Type 1 sexual headache is considered a variety of tension-type headache, while type 3 sexual headache is due to low cerebrospinal pressure, possibly due to a dural tear related to physical exercise.
Background: Occipital headache is considered a risk factor for serious secondary headache pathology.
Another alternative conceptual approach, the "severity model" of headache, considers a continuum of headache ranging from mild to severe forms with specific headache subtypes distinguished by level of severity rather than unique constellations of symptoms [30].
In CM, considered a complication of EM, headache attacks occur on ≥15 days/month for at least 3 months [1, 2].
Interestingly, however, smoking was considered a precipitant factor for migraine headache by 3.3% of migraine without aura subjects as compared of only 1.7% of tension-type headache.
