SUNCT syndrome
Short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT syndrome) is a rare headache disorder that belongs to the group of headaches called trigeminal autonomic cephalalgia (TAC). Symptoms include severe burning, stabbing, or electric headaches mainly near the eye and typically these sensations are only on one side of the body. The headache attacks are typically accompanied by cranial autonomic signs that are unique to SUNCT. Each attack lasts between five seconds to six minutes and may occur as often as 200 times per day. TACs are caused by activation of the autonomic nervous system pathways linked to the trigeminal nerve. As of 2015 about 50 cases have been described in the medical literature. Onset of the symptoms usually come later in life, at an average age of about 50. Although the majority of patients are men over the age of 50, it is not uncommon to find SUNCT present among other age groups, including children and infants.
