Nausea and vomiting are prominent headache-attack aborting features of migraine. Head-banging and other distressed behaviour including a marked restlessness characterize cluster headache while the migraine patient fears to move because of fear of increased or worsening of cranial pulsatile discomfort. Nausea/Vomiting do not form a phenotypic component of cluster headache.
Can we derive some pathophysiologic and therapeutic insight from such markedly different and striking headache -related behaviours?
Some patients exhibit both migraine attacks as well as cluster headache attacks. Where do we stand on this issue nosologically?
