Cluster Headache DefinitionCluster headaches are characterized by an intense one-sided pain centered by the eye or temple. The pain lasts for one to two hours on average and may recur several times in a day.DescriptionCluster headaches have been known as histamine headaches, red migraines, and Horton's disease, among others. The constant factor is the pain, which transcends by far the distress of the more common tension-type headache or even that of a migraine headache.Cluster headaches afflict less than 0.5% of the population and predominantly affect men; approximately 80% of sufferers are male. Onset typically occurs in the late 20s, but there is no absolute age restriction. Approximately 80% of cluster headaches are classified as episodic; the remaining 20% are considered chronic. Both display the same symptoms. However, episodic cluster headaches occur during oneto five-month periods followed by six to 24-month attack-free, or remission, periods. There is no such reprieve for chronic cluster headache sufferers.Causes and symptomsBiochemical, hormonal, and vascular changes induce cluster headaches, but why these changes occur remains unclear. Episodic cluster headaches seem to be linked to changes in day length, possibly signaling a connection to the so-called biological clock. Alcohol, tobacco, histamine, or stress can trigger cluster headaches. Decreased blood oxygen levels (hypoxemia) can also act as a trigger, particularly during the night when an individual is sleeping. Interestingly, the triggers do not cause cluster headaches during remission periods.The primary cluster headache symptom is excruciating one-sided head pain centered behind an eye or near the temple. This pain may radiate outward from the initial focus and encompass the mouth and teeth. For this reason, some cluster headache sufferers may mistakenly attribute their pain to a dental problem. Secondary symptoms, occurring on the same side as the pain, include eye tearing, nasal congestion followed by a runny nose, pupil contraction, and facial drooping or flushing. The primary cluster headache symptom is excruciating one-sided head pain located behind an eye or near the temple. Secondary symptoms include eye tearing, nasal congestion, and a runny nose. (Illustration by Electronic Illustrators Group.)DiagnosisCluster headache symptoms guide the diagnosis. A medical examination includes recording headache details, such as frequency and duration, when it occurs, pain intensity and location, possible triggers, and any prior symptoms. This history allows other potential problems to be discounted.TreatmentTreatment for cluster headaches is composed of induction, maintenance, and symptomatic therapies. The first two therapies are prophylactic treatments, geared toward preventing headaches. Symptomatic therapy is meant to stop or shorten a headache.Induction and maintenance therapies begin together. Induction therapy is intended to break the headache cycle with drugs such as corticosteroids (for example, prednisone) or dihydroergotamine. These drugs are not meant for long-term therapy, but rather as a jump-start for maintenance therapy. Maintenance therapy drugs include verapamil, lithium carbonate, ergotamine, and methysergide. These drugs have long-term effectiveness, but must be taken for at least a week before a response is observed. With long-term treatment, methysergide must be stopped for one month each year to avoid dangerous side effects (formation of fibrous tissue inside the abdominal artery, lungs, and heart valves).Despite prophylactic treatment, headaches may still occur. Symptomatic therapy includes oxygen inhalation, sumatriptan injection, and application of local anesthetics inside the nose. Surgery is a last resort for chronic cluster headaches that fail to respond to therapy.Alternative treatmentSince some cluster headaches are triggered by stress, stress reduction techniques, such as yoga, meditation, and regular exercise, may be effective. Some cluster headaches may be an allergic response triggered by food or environmental substances, therefore identifying and removing the allergen(s) may be key to resolution of the problem. Histamine is another suspected trigger of cluster headaches, and this response may be controlled with vitamin C and the bioflavonoids quercetin and bromelain (pineapple enzyme). Supplementation with essential fatty acids (EFA) will help decrease any inflammatory response.Physical medicine therapies such as adjustments of the spine, craniosacral treatment, and massage at the temporomandibular joint (TMJ) can clear blockages, as can traditional Chinese medical therapies including acupuncture. Homeopathic treatment can also be beneficial. Nervous system relaxant herbs, used singly or in combination, can allow the central nervous system to relax as well as assist in peripheral nerve response. A few herbs to consider for relaxation are valerian (Valeriana officinalis), chamomile (Matricaria recutita), rosemary (Rosemarinus officinalis), and skullcap (Scutellaria baicalensis).PrognosisIn general, drug therapy offers effective treatment.PreventionAvoiding triggers, adhering to medical treatment, and controlling stress can help ward off some cluster headaches.ResourcesOrganizationsAmerican Council for Headache Education (ACHE). 19 Mantua Road, Mt.

The headache is usually accompanied by other symptoms, such as nausea, vomiting, and aversion to light.Prophylactic — Referring to treatment that prevents symptoms from occurring.Tension-type headache — A dull pain that seems to exert pressure on the head; the most common form of headache.headache [hed´āk] pain in the head; see also migraine. One of the most common ailments of humans, it is a symptom rather than a disorder in itself; it accompanies many diseases and conditions, including emotional distress. Although recurring headache may be an early sign of serious organic disease, relatively few headaches are caused by disease-induced structural changes. Most result from vasodilation of blood vessels in tissues surrounding the brain, or from tension in the neck and scalp muscles.
Immediate attention by a health care provider is indicated when (1) a severe headache comes on suddenly without apparent cause; (2) there are accompanying symptoms of neurological abnormality, for example, blurring of vision, mental confusion, loss of mental acuity or consciousness, motor dysfunction, or sensory loss; or (3) the headache is highly localized, as behind the eye or near the ear, or in one location in the head. Fever and stiffness of the neck accompanying the headache may indicate meningitis.cluster headache a migraine-like disorder marked by attacks of unilateral intense pain over the eye and forehead, with flushing and watering of the eyes and nose; attacks last about an hour and occur in clusters.exertional headache one occurring after exercise.histamine headache cluster headache.lumbar puncture headache headache in the erect position, and relieved by recumbency, following lumbar puncture, due to lowering of intracranial pressure by leakage of cerebrospinal fluid through the needle tract.migraine headache migraine.organic headache headache due to intracranial disease or other organic disease.tension headache a type due to prolonged overwork or emotional strain, or both, affecting especially the occipital region.toxic headache headache due to systemic poisoning or associated with illness.vascular headache a classification for certain types of headaches, based on a proposed etiology involving abnormal functioning of the blood vessels or vascular system of the brain; included are migraine, cluster headache, toxic headache, and headache caused by elevated blood pressure.clus·ter head·achepossibly due to a hypersensitivity to histamine; characterized by recurrent, severe, unilateral orbitotemporal headaches associated with ipsilateral photophobia, lacrimation, and nasal congestion.
