Which of the following is not a feature of cluster headache ?
Cluster headache occur three times more common in men than in women. Cluster headache is likely a disorder involving central pacemaker neurons in the region of the posterior hypothalamus. It is associated with symptoms such as conjunctival injection or lacrimation, rhinorrhea or nasal congestion, or cranial sympathetic dysfunction such as ptosis. These defects occur due to parasympathetic activation which occur as a result of injury to ascending sympathetic fibers surrounding a dilated carotid aery as it passes into the cranial cavity.
