Trigeminal Autonomic Cephalgias

This is a group of headaches in which the pain can be somewhat similar to cluster headache, but other characteristics of the headache may be different, particularly the timing. The common features of the “autonomic” headaches are those symptoms that involve the autonomic nervous system, such as tears, redness of the eye, nasal stuffiness, pupil change, drooping of the eyelid, redness of the cheek or pain in the region of the eye.
