<![CDATA[Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) are a subset of short-lasting unilateral neuralgiform headache attacks. SUNCT is a condition that is rarely encountered and is characterized by typical moderate to severe neuralgia pain located in the first division area of the trigeminal nerve that can be felt in any part of the head. SUNCT can be primary and secondary. Typical SUNCT symptoms include severe unilateral headache with autonomic symptoms with bilateral conjunctival injection and lacrimation with an attack frequency more than 60 times per day (range 3 to 200) which can occur spontaneously or be triggered by a mechanical stimulus in an area that is innervated by the trigeminal nerve , and without a refractory period thereafter. The current treatment is still diverse, including therapy with anti-epileptic drugs, interventional therapy, or invasive procedures. The diagnosis and management of complex therapies in patients with SUNCT still need further understanding.]]>
