There are four major types of headache: vascular, muscle contraction (tension), traction, and inflammatory. The most common type of vascular headache is a migraine. Migraine headaches are usually characterized by severe pain on one or both sides of the head, nasuea, and, at times, disturbed vision. Women are more likely than men to have migraine headaches.
Vestibular paroxysmia. Vestibular paroxysmia is also referred to as disabling positional vertigo, vascular loop syndrome or microvascular compression syndrome in the literature. Other vascular compression syndromes include trigeminal neuralgia and hemifacial spasm. Vestibular paroxysmia is a controversial syndrome. It is believed that a blood vessel, which forms a loop around the vestibular branch of the cochleovestibular nerve (VIII cranial nerve) is responsible.
