Migraine is the first book written by Oliver Sacks, a well-known New York City-based neurologist and author. The full title of the first edition was Migraine - Evolution of a Common Disorder. The book was written in 1967, mostly over a nine-day period, [1] and first published in 1970. A revised and updated version was published in 1992. (In the newer edition, the last chapter Migraine Aura and Hallucinatory Constants was written in collaboration with Ralph M. Siegel. [2] )
As with Sacks's other writings, Migraine is a comprehensive review of the subject aimed at the lay population and uses numerous case histories. [3] Sacks describes the nature of and treatments for migraine in general and several various subtypes, particularly examining the visual aura feature that is common to many sufferers, along with the pre-migraine signs & symptoms. The particular focus of the book, however, is on the neuropsychological aspects of migraine. [3]
The book is divided into five sections: [3]
In an interview with Neil deGrasse Tyson about the possible merits of altered states of consciousness by means of psychoactive substance, Sacks revealed that in 1967 he had a revelation when he was under the influence of an undisclosed psychoactive substance while reading a book written in the 19th century about headaches and migraines. This book was written by Edward Liveing, an early and important contributor in theories of migraine pathogenesis. As he was reading the book he had an awakening and thought to himself, "Who shall be the Edward Liveing of our time? And there was a very disingenuous clamor of names that came to me, followed by a very loud inner voice which said, 'You Silly Bugger! You're the man!'" [4]
Migraine is a genetically influenced complex neurological disorder characterized by episodes of moderate-to-severe headache, most often unilateral and generally associated with nausea and light and sound sensitivity. Other characterizing symptoms may include nausea, vomiting, cognitive dysfunction, allodynia, and dizziness. Exacerbation of headache symptoms during physical activity is another distinguishing feature. Up to one-third of migraine sufferers experience aura, a premonitory period of sensory disturbance widely accepted to be caused by cortical spreading depression at the onset of a migraine attack. Although primarily considered to be a headache disorder, migraine is highly heterogenous in its clinical presentation and is better thought of as a spectrum disease rather than a distinct clinical entity. Disease burden can range from episodic discrete attacks, consisting of as little as several lifetime attacks, to chronic disease.
Headache, also known as cephalalgia, is the symptom of pain in the face, head, or neck. It can occur as a migraine, tension-type headache, or cluster headache. There is an increased risk of depression in those with severe headaches.
Micropsia is a condition affecting human visual perception in which objects are perceived to be smaller than they actually are. Micropsia can be caused by optical factors, by distortion of images in the eye, by changes in the brain, and from psychological factors. Dissociative phenomena are linked with micropsia, which may be the result of brain-lateralization disturbance.
A medication overuse headache (MOH), also known as a rebound headache, usually occurs when painkillers are taken frequently to relieve headaches. These cases are often referred to as painkiller headaches. Rebound headaches frequently occur daily, can be very painful and are a common cause of chronic daily headache. They typically occur in patients with an underlying headache disorder such as migraine or tension-type headache that "transforms" over time from an episodic condition to chronic daily headache due to excessive intake of acute headache relief medications. MOH is a serious, disabling and well-characterized disorder, which represents a worldwide problem and is now considered the third-most prevalent type of headache. The proportion of patients in the population with Chronic Daily Headache (CDH) who overuse acute medications ranges from 18% to 33%. The prevalence of medication overuse headache (MOH) varies depending on the population studied and diagnostic criteria used. However, it is estimated that MOH affects approximately 1-2% of the general population, but its relative frequency is much higher in secondary and tertiary care.
Visual snow syndrome (VSS) is an uncommon neurological condition in which the primary symptom is that affected individuals see persistent flickering white, black, transparent, or coloured dots across the whole visual field.
A cold-stimulus headache, colloquially known as an ice-cream headache or brain freeze, is a form of brief pain or headache commonly associated with consumption of cold beverages or foods such as ice cream, popsicles, and snow cones. It is caused by a cold substance touching the roof of the mouth, and is believed to result from a nerve response causing rapid constriction and swelling of blood vessels, "referring" pain from the roof of the mouth to the head. The rate of intake for cold foods has been studied as a contributing factor. It can also occur during a sudden exposure of unprotected head to cold temperatures, such as by diving into cold water. A cold-stimulus headache is distinct from dentin hypersensitivity, a type of dental pain that can occur under similar circumstances.
Triptans are a family of tryptamine-based drugs used as abortive medication in the treatment of migraines and cluster headaches. This drug class was first commercially introduced in the 1990s. While effective at treating individual headaches, they do not provide preventive treatment and are not considered a cure. They are not effective for the treatment of tension–type headache, except in persons who also experience migraines. Triptans do not relieve other kinds of pain.
Butalbital is a barbiturate with an intermediate duration of action. Butalbital is often combined with other medications, such as paracetamol (acetaminophen) or aspirin, for the treatment of pain and headache. The various formulations combined with codeine are FDA-approved for the treatment of tension headaches. Butalbital has the same chemical formula as talbutal but a different structure—one that presents as 5-allyl-5-isobutylbarbituric acid.
Acephalgic migraine is a neurological syndrome. It is a relatively uncommon variant of migraine in which the patient may experience some migraine symptoms such as aura, nausea, photophobia, and hemiparesis, but does not experience headache. It is generally classified as an event fulfilling the conditions of migraine with aura with no headache. It is sometimes distinguished from visual-only migraine aura without headache, also called ocular migraine.
Scintillating scotoma is a common visual aura that was first described by 19th-century physician Hubert Airy (1838–1903). Originating from the brain, it may precede a migraine headache, but can also occur acephalgically, also known as visual migraine or migraine aura. It is often confused with retinal migraine, which originates in the eyeball or socket.
Hemiplegic migraine is a type of migraine headache characterized by motor weakness affecting only one side of the body, accompanied by aura. There is often an impairment in vision, speech, or sensation. It can run in the family, called familial hemiplegic migraine, or in a single individual, called sporadic hemiplegic migraine. The symptoms can be similar to a stroke, and may be precipitated by minor head trauma. People with FHM are advised to avoid activities that may trigger their attacks.
The International Classification of Headache Disorders (ICHD) is a detailed hierarchical classification of all headache-related disorders published by the International Headache Society. It is considered the official classification of headaches by the World Health Organization, and, in 1992, was incorporated into the 10th edition of their International Classification of Diseases (ICD-10). Each class of headache contains explicit diagnostic criteria—meaning that the criteria include quantities rather than vague terms like several or usually—that are based on clinical and laboratory observations.
Vestibular migraine (VM) is vertigo with migraine, either as a symptom of migraine or as a related neurological disorder.
The classification of all headaches, including migraines, is organized by the International Headache Society, and published in the International Classification of Headache Disorders (ICHD). The current version, the ICHD-3 beta, was published in 2013.
Anne MacGregor is a New Zealand-born British medical researcher and clinician based in London. She is a leading researcher in the field of hormonal effects on migraine.
Migralepsy is a rare condition in which a migraine is followed, within an hour period, by an epileptic seizure. Because of the similarities in signs, symptoms, and treatments of both conditions, such as the neurological basis, the psychological issues, and the autonomic distress that is created from them, they individually increase the likelihood of causing the other. However, also because of the sameness, they are often misdiagnosed for each other, as migralepsy rarely occurs.
Abdominal aura, also known as visceral aura and epigastric aura, is a type of somatosensory aura that typically manifests as abdominal discomfort in the form of nausea, malaise, hunger, or pain. Abdominal aura is typically associated with epilepsy, especially temporal lobe epilepsy, and it can also be used in the context of migraine. The term is used to distinguish it from other types of somatosensory aura, notably visual disturbances and paraesthesia. The abdominal aura can be classified as a somatic hallucination. Pathophysiologically, the abdominal aura is associated with aberrant neuronal discharges in sensory cortical areas representing the abdominal viscera.
Migraine is often hereditary. It is estimated that 60% of migraine cases are caused by genetics. The role of natural selection in the development of migraines is not known. Fitness-impairing disorders, including migraines, tend to disappear as a result of natural selection, and their frequency decreases to near the rate of spontaneous mutation. However, it is estimated that migraines affect 15-20% of the population and is increasing. This could suggest that a central nervous system (CNS) susceptible to severe, intermittent headache has been linked to an important survival or reproductive advantage. Five possible evolutionary explanations exist: i) migraine as a defence mechanism, ii) migraine as a result of conflicts with other organisms, iii) migraine as a result of novel environmental factors, iv) migraine as a compromise between genetic harms and benefits, and v) headache as a design constraint. These considerations allow the treatment and prevention of migraine to be approached from an evolutionary medicine perspective.
Edward Liveing was an English physician who published a theory of migraine pathogenesis in his book On Megrim.
Menstrual migraine is the term used to describe both true menstrual migraines and menstrually related migraines. About 7%–14% of women have migraines only at the time of menstruation. These are called true menstrual migraines. Most female migraineurs experience migraine attacks throughout the menstruation cycle with an increased number perimenstrually, these are referred to as menstrually related or menstrually triggered migraine.
