|
Autonomic symptoms are the prominent features of cluster headache and relatively common symptoms of migraine. Additionally, autonomic signs can be the clue of secondary headache such as dissection of carotid artery and parasellmar mass. Autonomic symptoms, which are conjunctival injection or lacrimation, nasal congestion or rhinorrhea, miosis or ptosis, eyelid edema, and forehead and facial sweating, are very common in cluster headache. Trigeminal-autonomic reflex is the suggest mechanisms of lacrimation or rhinorrhea. Sympathetic hypofunction due to central mechanism or compression of sympathetic trunk by vasodilatation is involved in miosis. Brain stimulation on autonomic ganglion or hypothalamus is the possible therapeutic option for cluster headache. Autonomic symptoms in migraine are usually mild and bilateral than those in cluster headache. Severity of headache may be related to autonomic activation during headache attack. In conclusion, autonomic symptoms in headache are related to pathophysiology of headache and can be the door
to new therapeutic approaches.
