Cluster Headache associates a severe pain generally unilateral and autonomic symptoms with a remarkable periodicity. In the first part we tried to explain the conception of physiopathology of these short lasting headache syndromes and in the second part we described the clinical features. The short lasting primary headaches are divided into two groups: those with marked autonomic activation which comprise chronic and episodic paroxysmal hemicrania, short lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT syndrome) and cluster headache. The second group includes two entities, one without autonomic activation: Hypnic Headache and one with mild autonomic features: Hemicrania Continua. The paroxysmal hemicranias are characterized by attack frequency ranges from 15 to 20 per day of short lasting attacks of unilateral pain that typically last 2 to 10 minutes, the severe pain is associated with autonomic symptoms and responds to treatment with indomethacin. The SUNCT syndrome has a less severe pain but marked autonomic activation during attacks, this syndrome is actually resistant to proposed therapy. The Hypnic Headache and the Hemicrania Continua have yet less severe pain with very mild or without autonomic features.

Idiopathic stabbing headaches, the SUNCT syndrome, and the paroxysmal hemicranias are a group of primary headache disorders that are characterized by brief, short-lived attacks of head pain, which recur multiple times throughout the day. These syndromes are much less prevalent than other types of primary headaches such as migraine and tension-type headaches but are significantly more disabling. Recognition of these uncommon disorders is important because their management differs from standard headache therapies.

The syndrome of short-lasting unilateral, neuralgiform attacks of pain in the peri orbital area associated with conjunctival injection and tearing (SUNCT) is a rare disorder affecting mainly males. We report two French patients (1 male and 1 female) with SUNCT syndrome, 27 and 28 years of age respectively. Both patients had short (30 sec), frequent (30-100/day) excruciating pain located at the peri orbital area, associated with conjunctival injection, tearing, rhinorrhea, ptosis and others vasomotor symptoms. Clinical examination and imaging were normal. Most drugs used in the treatment of migraine, cluster headache, trigeminal neuralgia, and other short-lasting headaches were not successful.

Trigeminal neuralgia solely involving the upper trigeminal nerve branch is rare. The SUNCT syndrome (short-lasting, unilateral, neuralgiform hemicrania with conjunctival injection and tearing) in which the periorbital pain lasts for 60-120 s, and is accompanied by conjunctival injection and tearing is even less common. Unlike trigeminal neuralgia, SUNCT is usually not relieved by medication. Three patients with SUNCT were treated with retrogasserian glycerol rhizolysis, two of them twice. All five treatments provided complete pain relief and the duration of the effects was 2 to more than 4 years. One of these three patients also had a third treatment with compression of retroganglionic fibres with a Fogarthy balloon, according to Mullan, of the upper trigeminal nerve with excellent results.

Short-lasting Unilateral Neuralgiform headache attacks with Conjunctival injection and Tearing (SUNCT) is a syndrome predominant in males, with a mean age of onset around 50 years. The attacks are strictly unilateral, generally with the pain persistently confined to the ocular/periocular area. Most attacks are moderate to severe in intensity and burning, stabbing or electrical in character. The mean duration of paroxysms is 1 minute, with a usual range of 10 to 120 seconds (total range 5 to 250 seconds). Prominent, ipsilateral conjunctival injection and lacrimation regularly accompany the attacks. Nasal stuffiness/rhinorrhoea are frequently noted. In addition, there is subclinical forehead sweating. During attacks, there is increased intraocular pressure on the symptomatic side and swelling of the eyelids. No changes in pupil diameter have been observed. Attacks can be triggered mostly from trigeminally innervated areas, but also from the extratrigeminal territory. There are also spontaneous attacks. An irregular temporal pattern is the rule, with symptomatic periods alternating with remissions in an unpredictable fashion. During active periods, the frequency of attacks may vary from <1 attack/day to >30 attacks/hour. The attacks predominate during the daytime, nocturnal attacks being seldom reported. A SUNCT-like picture has been described in some patients with either intra-axial or extra-axial posterior fossa lesions, mostly vascular disturbances/ malformations. In the vast majority of patients, however, aetiology and pathogenesis are unknown. In SUNCT syndrome, there is a lack of persistent, convincingly beneficial effect of drugs or anaesthetic blockades that are generally effective in cluster headache, chronic paroxysmal hemicrania, trigeminal neuralgia, idiopathic stabbing headache ('jabs and jolts syndrome'), and other headaches more faintly resembling SUNCT syndrome. Single reports have claimed that carbamazepine, lamotrigine, gabapentin, corticosteroids or surgical procedures may be of help. However, caution is recommended when assessing any therapy in a disorder such as SUNCT syndrome, in which the rather chaotic and unpredictable temporal pattern makes the assessment of any drug/therapeutic effect per se a particularly difficult matter.

The clinical features of short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) syndrome have been reviewed in 50 patients reported in the English language literature. SUNCT syndrome is a rare condition that predominates slightly in men. The mean age at onset is 50 years. It is characterized by strictly unilateral attacks centered on the orbital or periorbital regions, forehead, and temple. Generally, the pain is severe and neuralgic in character. The usual duration ranges from 5 to 250 seconds, although the reported range of duration is 2 seconds to 20 minutes. Ipsilateral conjunctival injection and lacrimation are present in most, but not all patients. Most patients are thought to have no refractory periods and this has probably been unreported in the past. Episodic and chronic forms of SUNCT exist. The attack frequency varies from less than one attack daily to more than 60 attacks per hour. The attacks are predominantly diurnal, although frequent nocturnal attacks can occur in some patients. A functional magnetic resonance imaging study in SUNCT syndrome has demonstrated ipsilateral hypothalamic activation. SUNCT was thought to be highly refractory to treatment. However, recent open-label trials of lamotrigine, gabapentin, topiramate, and intravenous lidocaine have produced beneficial therapeutic responses. These results offer the promise of better treatments for this syndrome, but require validation in controlled trials.

The trigeminal autonomic cephalgias (TACs) are a group of primary headache disorders characterised by unilateral trigeminal distribution pain that occurs in association with ipsilateral cranial autonomic features. This group of headache disorders includes cluster headache, paroxysmal hemicrania and short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT syndrome). Although hemicrania continua has previously been classified amongst the TACs, its nosological status remains unclear. Despite their similarities, these disorders differ in their clinical manifestations and response to therapy, thus underpinning the importance of recognising them. We have outlined the clinical manifestations, differential diagnoses, diagnostic workup and the treatment options for each of these syndromes.

A number of primary headache syndromes are marked by their short duration of pain. Many of these syndromes have their own unique treatment, so they must be recognized by practicing physicians. In this article, a number of the short-lasting headache disorders are reviewed, including chronic paroxysmal hemicrania, SUNCT syndrome, hypnic headache, exploding head syndrome, primary stabbing headache, and cough headache.

Trigeminal autonomic cephalgias; cluster headache, paroxysmal hemicrania, hemicrania continua and SUNCT (short-lasting unilateral neuralgiform headache attacks with conjuctival injection and tearing) syndrome are characterized by unilateral trigeminal distribution of pain and accompanying ipsilateral autonomic symptoms. Other than cluster headache, all of these syndromes have been described within last twenty years, and are found relatively less frequent and less known forms. Diagnosis of paroxysmal hemicrania and hemicrania continua, especially atypical forms, essentially depends on indomethacin responsiveness. For SUNCT syndrome, there is not such a drug which provides a practical approach to both diagnosis and therapy and its diagnosis depends on clinical features. So far, case reports from various countries helped us realize the existence of secondary forms of these syndromes and the necessity of imaging techniques, especially for recently described autonomic cephalgias.

Following the new IHS classification, cluster headache, paroxysmal hemicrania, and short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT syndrome) are included in the classification as trigeminal autonomic cephalgias (TAC). The similarities of these syndromes suggest a considerable shared pathophysiology. These syndromes have in common that they involve activation of trigeminovascular nociceptive pathways with reflex cranial autonomic activation. Clinically, this physiology predicts pain with some combination of lacrimation, conjunctival injection, nasal congestion, or eyelid edema. Broadly the management of TAC comprises acute and prophylactic treatment. Some types of trigeminal autonomic headaches such as paroxysmal hemicrania and hemicrania continua have, unlike cluster headaches, a very robust response to indomethacin, leading to a consideration of indomethacin-sensitive headaches. This review covers the clinical picture and therapeutic options. Although studies following the criteria of evidence-based medicine (EBM) are rare, most patients can be treated sufficiently.
