    We describe the case of a 40-year-old woman, affected by episodic cluster headache, who presented with a cluster headache triggered by exposure to high altitude. Her attacks were refractory to sumatriptan, very effective at sea level, but responded to oxygen. A pathophysiological mechanism is proposed

    MIGRALEPSY: A TOO NARROW DEFINITION?

    No full text
    The relationship between epilepsy and migraine is complex and remains to be determined. We report 3 cases that address 2 questions on this topic. The first and second cases showed an association between migraine without aura and the onset of epileptic seizures. The third case report describes a patient in whom migraine with aura occurred and was followed by the development of status epilepticus, which occurred 2 or 3 hours after the attack of migraine with aura. We discuss the present definition of migralepsy and reassess its definition by suggesting possible extensions to its current definition
