Primary headache disorders (migraine, tension headache, and cluster headache) make up nearly 98% of all headaches; there are an estimated 1 million people with cluster headache in the United States; approximately 90 percent of people who suffer from it are men. The outbreak is one of the least common types of headache and the cause is unknown. Similar to migraine, pain is related to the inflammatory process resulting from an interaction between the trigeminal nerve and blood vessels in the covers of the brain. Abnormalities in the hypothalamus, a deep area of the brain that controls circadian rhythms, may be responsible for the pattern of cluster headaches.
Some headache patterns are also generally considered primary headache types, but they are less common. These headaches have different characteristics, such as an unusual duration or pain associated with a certain activity. Cluster headaches are characterized by severe pain of sudden onset, usually behind one eye. They are the most serious type of headache, but are less common than tension headaches and migraines.
Cluster headaches tend to occur in groups, sometimes daily or several times a day. They last 1 to 3 hours, and the pain recurs in the same way every time. Patients should be careful to avoid overuse of analgesics due to the high frequency of this type of headache. Steiner et al (201) 41 propose a three-tiered model of care in which 90% of headaches are attended by primary care physicians (Level with minimal training in headache disorders through educational conferences given in a local setting).
Approximately 98% of patients who present for medical evaluation will have a primary type of headache. Chronic migraine, drug overuse and CT scan account for the vast majority of incapacitating headaches that are misdiagnosed and poorly managed and should be referred to doctors with an interest and experience in headaches. Migraines and tension headaches account for the vast majority of the remaining headaches (95%) that occur in primary or secondary care. It describes the role of the national society, the British Association for the Study of Headache and patient organisations such as Migraine Trust in headache education for professionals and the general public in shaping headache care in the United Kingdom.
In addition, studies have focused on a specific headache disorder (and compared patients with controls without headache) and, therefore, there are no data on the diagnostic applicability of these measurements to discriminate between different primary headaches. They may not recognize that the direct costs of treating headache are small compared to the huge indirect cost savings that could be achieved (for example, by reducing lost workdays) if resources were allocated to treat headache disorders appropriately. The most crucial aspect of headache diagnosis is history (Table; most patients, including those with common secondary headaches, have no signs and research is rarely required to exclude a secondary headache. People who suffer from migraine may experience a variety of headache presentations including sinus pain, neck tension, menstrual migraine or having aura without a headache.
Patients who come to the emergency department with a headache complaint should be evaluated and a distinction should be made between common primary and life-threatening secondary headaches. As discussed above, primary headache disorders include tension-type headaches, cluster headaches, and migraine headaches (with and without aura). This initiative began in 2004 and aims not only to raise awareness of headache disorders, but also to improve the quality of headache care and access to it worldwide. Primary headaches are among the most prevalent disorders in humanity, the prevalence of migraine at 1 year is around 10 to 14% and tension headache above 40% Primary headaches involve biological disorders of the brain that occur with headache without evidence of underlying structural lesions.
