  • Headache: General Considerations CQ I-1
    I Headache: General Considerations CQ I-1 How is headache classified and diagnosed? Recommendation Headache should be classified and diagnosed according to the International Classification of Headache Disorders 3rd edition (beta version). Grade A Background and Objective In 2004, the International Headache Society (IHS) revised the first edition of the IHS guideline for the first time in 15 years, incorporating the latest advances in research, evidence and criticisms. The resulting document, International Classification of Headache Disorders 2nd Edition (ICHD-2) was published in Cephalalgia.1) In the same year, the ICHD-2 was translated into Japanese and published.2) From 2004, headache should be classified and diagnosed in accordance with the ICHD-2. The first recorded classification of headache was by Aretaeus (a physician born in 81 BC) of Cappadacia in the present day Turkey, who classified headaches into cephalalgia, cephalea, and heterocrania.3)-5) Heterocrania was described as “half head” headache, which is equivalent to migraine in the present day classification. The first consensus-orientated headache classification in history was the classification by the Ad Hoc Committee on Classification of Headache of the American Neurological Association (Ad Hoc classification) published in 1962.6) In this classification, headache was classified into 15 types, but no diagnostic criteria were included. In 1988, the Headache Classification Committee of the International Headache Society chaired by Olesen proposed the first international classification of headache disorders (IHS Classification,st 1 edition, 1988).7) The IHS Classificationst 1 edition first classified headache into 13 items, and further subdivided into 165 headache types. For each subtype, operational criteria were described.

Brennan, MD • Seniha Ozudogru, MD 729 Arapeen Drive Salt Lake City, Utah 84108 801.585.7575 headache.uofuhealth.org Headache: A Patient’s Guide eadache is an extremely common problem. It is estimated that 10-20% of all people have migraine. Headache is one of the most common reasons H people visit the doctor’s office. Headache can be the symptom of a serious problem, or it can be recurrent, annoying and disabling, without any underlying structural cause. WHAT CAUSES HEAD PAIN? Pain in the head is carried by certain nerves that supply the head and neck. The trigeminal system impacts the face as well as the cervical (neck) 1 and 2 nerves in the back of the head. Although pain can indicate that something is pushing on the brain or nerves, most of the time nothing is pushing on anything. We think that in migraine there may be a generator of headache in the brain which can be triggered by many things. Some people’s generators are more sensitive to stimuli such as light, noise, odor, and stress than others, causing a person to have more frequent headaches. THERE ARE MANY TYPES OF HEADACHES! Most people have more than one type of headache. The most common type of headache seen in a doctor's office is migraine (the most common type of headache in the general population is tension headache). Some people do not believe that migraine and tension headaches are different headaches, but rather two ends of a headache continuum.

Migraine affects a substantial fraction of world population and is a major cause of disability in the work place. Though the pathophysiology of migraine is still unclear three major theories proposed with regard to the mechanisms of migraine are vascular (due to cerebral vasodilatation), neurological (abnormal neurological firing which causes the spreading depression and migraine) and neurogenic dural inflammation (release of inflammatory neuropeptides). The modern understanding of the pathogenesis of migraine is based on the concept that it is a neurovascular disorder. The drugs used in the treatment of migraine either abolish the acute migraine headache or aim its prevention. The last decade has witnessed the advent of Sumatriptan and the Ftriptan_ class of 5-HT1B/1D receptor agonists which have well established efficacy in treating migraine. Currently prophylactic treatments for migraine include calcium channel blockers, 5-HT2 receptor antagonists, beta adrenoceptor blockers and g-amino butyric acid (GABA) agonists. Unfortunately, many of these treatments are non specific and not always effective. Despite such progress, in view of the complexity of the etiology of migraine, it still remains undiagnosed and available therapies are underused.

  • Migraine: Spectrum of Symptoms and Diagnosis
    KEY POINT: MIGRAINE: SPECTRUM A Most patients develop migraine in the first 3 OF SYMPTOMS decades of life, some in the AND DIAGNOSIS fourth and even the fifth decade. William B. Young, Stephen D. Silberstein ABSTRACT The migraine attack can be divided into four phases. Premonitory phenomena occur hours to days before headache onset and consist of psychological, neuro- logical, or general symptoms. The migraine aura is comprised of focal neurological phenomena that precede or accompany an attack. Visual and sensory auras are the most common. The migraine headache is typically unilateral, throbbing, and aggravated by routine physical activity. Cutaneous allodynia develops during un- treated migraine in 60% to 75% of cases. Migraine attacks can be accompanied by other associated symptoms, including nausea and vomiting, gastroparesis, di- arrhea, photophobia, phonophobia, osmophobia, lightheadedness and vertigo, and constitutional, mood, and mental changes. Differential diagnoses include cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoenphalopathy (CADASIL), pseudomigraine with lymphocytic pleocytosis, ophthalmoplegic mi- graine, Tolosa-Hunt syndrome, mitochondrial disorders, encephalitis, ornithine transcarbamylase deficiency, and benign idiopathic thunderclap headache.

  • Tension-Type Headache CQ III-1
    III Tension-type headache CQ III-1 How is tension-type headache classified? Recommendation Since 1962, various classifications for tension-type headache have been proposed. Currently, classification according to the International Classification of Headache Disorders 3rd Edition (beta version) (ICHD-3beta) published in 2013 is recommended. Grade A Background and Objective Diagnostic classification that forms the basis of guidelines is certainly important for formulating clinical care and treatment policies. The ICHD-3beta is not simply a document based on classification, it also addresses diagnosis and treatment scientifically and practically from all aspects. Comments and Evidence The classification of tension-type headache (TTH) is provided by the International Classification of Headache Disorders 3rd edition beta version (ICHD-3beta).1)2) The division of tension-type headache into episodic and chronic types adopted by the first edition of the International Classification of Headache Disorders (1988)3) is extremely useful. The International Classification of Headache Disorders 2nd edition (ICHD-II) further subdivides the episodic type according to frequency, and states that this is based on the difference in pathophysiology. The former episodic tension-type headache (ETTH) is further classified into 2.1 infrequent episodic tension-type headache (IETTH) with headache episodes less than once per month (<12 days/year), and 2.2 frequent episodic tension-type headache (FETTH) with higher frequency and longer duration (<15 days/month). The infrequent subtype has little impact on the individual, and to a certain extent, is understood to be within the range of physiological response to stress in daily life. However, frequent episodes may cause disability that sometimes requires expensive drugs and prophylactic medication.
