title: A Practical Approach to Autonomic Dysfunction in Patients with Headache.
abstract: The presence of autonomic symptoms can make the diagnosis of headache challenging. While commonly seen with the trigeminal autonomic cephalalgias, autonomic dysfunction can also be present in patients with migraine, or with a variety of secondary headaches. The pathophysiology of cranial autonomic symptoms in headache is based between the trigeminal system and the hypothalamus. This article will review the pathophysiology and presence of autonomic dysfunction in headache and will provide techniques to help in headache diagnosis in patients with autonomic dysfunction.
