IHS Criteria for Migraine and Tension-Type Headache in Children and Adolescents

We investigated the influence of age on the IHS criteria for migraine and tension-type headache in 437 consecutive children and adolescents and found the following age-associated statistically significant differences: migraine duration, occurrence of migraine aura, and bilateral location of tension-type headache were more often fulfilled by adolescents, whereas aggravation of headache by physical activity (in migrainous disorder) and photophobia (in migraine with aura) were more often fulfilled by children, Accordingly, there are only a few, differences concerning the fulfillment of the IHS criteria for migraine and tension-type headache in children and adolescents. Independent of age, the intensity of headache and the presence or absence of nausea are most important for differentiating the two major types of idiopathic headache. The sensitivity of the IHS criteria for migraine could be increased by reducing the minimum duration of migraine and by allowing the diagnosis of migraine when severe headache is associated with nausea, even though the criteria of location, quality, and aggravation by physical activity are not fulfilled.     

Diagnosing Recurring Headaches: IHS Criteria and Beyond

SYNOPSIS
Current classification systems for diagnosing recurring headaches utilize sets of specific criteria. To determine the usefulness of these criteria in the practical application of diagnosing headache patients, 698 headache specialists were asked to review four case vignettes of headache patients and assign a diagnosis. They also ranked International Headache Society (IHS) criteria along with other features commonly used in the diagnosis of headaches in order of importance. There was no difference in ranked importance for the specific criteria posed by the IHS compared with commonly used criteria not included within the IHS system. A large majority of the respondents combined IHS features with other associated features not used in the IHS system as the basis of diagnostic assignment. These results raise a question about the acceptance and utilization of the IHS system as a basis for diagnoses. They also suggest that there is a need to educate health care providers about the appropriate use of the current IHS criteria to increase reliability of headache diagnosis.     

Classification of Daily and Near-Daily Headaches: Proposed Revisions to the IHS Criteria

SYNOPSIS
The International Headache Society (IHS) headache classification, while a major advance, does not adequately classify the daily and near-daily headache disorders known as chronic daily headache (CDH). We believe that chronic daily headache is a group of disorders which includes chronic tension-type headache (CTTH), transformed migraine (TM), new daily persistent headache (NDPH), and hemicrania continua (HC). We propose specific criteria for transformed migraine, new daily persistent headache, and hemicrania continua, and have modified the criteria for chronic tension-type headache.     

Young Adults With Headaches: The Transition From Adolescents to Adults

Migraine is a common condition that for many begins in childhood and may progress over the course of one's life. The transition from adolescence to adulthood is a critical time for those who suffer from migraine and can be marked by a variety of important considerations for the patient and practitioner. Medication choices may be a challenge during adolescent years as Food and Drug Administration (FDA) approved options are few and many more studies are needed to understand the benefits and risks of use of these agents in adolescents. However, as patients transition to adulthood, FDA approved options and the level of evidence improve significantly. Late adolescents may also struggle with a variety of psychiatric comorbidities that may simultaneously create challenges in determining treatment but also open opportunities to manage multiple comorbidities and address underlying depression, anxiety, and behavioral issues. For late adolescent girls, the beginning of sexual activity, onset of gynecologic conditions, or presence of irregular or painful menses may raise questions regarding the use of oral contraceptives (OCs). Given data on the risks of these medications in women with migraine, especially those with aura or those who smoke, important conversations between physicians and their migraine patients can help risk stratify and determine the risk/benefit profile for the potential use of these agents. Much more data are needed to fully understand the transition from adolescence to adulthood for those suffering with migraine and this article seeks to shed light on the limited understanding currently available in established literature.     

Migraine in children – an evaluation of the IHS criteria

The purpose of the present study was to compare the new criteria by the International Headache Society (IHS) with criteria for the definition of childhood migraine previously used. In particular, we considered the problem of the minimally acceptable headache duration in children. In a postal questionnaire, 36.5% of 3580 children 8–9 years old reported headache attacks. Ninety-five children (2.7%) fulfilled the IHS criteria. Three percent fulfilled the previously used migraine definition of Vahlquist. Some of the children in the latter group had considerably shorter headache attacks than those of the IHS patients, but otherwise their symptoms were very similar. When the IHS criterion of headache attack duration was lowered from a minimum of 2 h to 1 h, or omitted, the number of migraine patients increased from 95 to 114 and 127, respectively.     

Clinical Feature: Migraine in Adolescents

Approximately 10% of children and adolescents suffer from migraines. They typically present to their primary care provider with recurrent, moderate to severe headaches, lasting 2 to 72 hours. Migraines can be disabling, causing adolescents to miss school and extracurricular activities. Taking a thorough history is crucial to making an accurate diagnosis and ruling out more serious conditions. Treatment for adolescent migraines includes lifestyle management, abortive medications, nonpharmacologic interventions such as cognitive behavioral therapy, and preventative medications if necessary. The future of treatment may be enhanced via training of more providers to deliver cognitive behavioral therapy and the development of Web-based delivery.     

Possible Identification of Cervicogenic Headache Among Patients With Migraine: An Analysis of 374 Headaches

According to Sjaastad, the pain in cervicogenic headache, a form not recognized by the IHS, is long lasting and always side-locked unilateral. The frequency of side-locked unilateral pain (defined here as no change in side from onset) and other characteristics of cervicogenic headache were investigated in 300 outpatients using information collected on standard forms in structured interviews. Three hundred seventy-four headaches diagnosed according to IHS criteria were identified. Three hundred forty-eight of these headaches were long-lasting (duration of more than 4 hours); migraine (65%) followed by tension-type headache (25%) were the commonest forms. Side-locked unilaterality was present in 29% (101 of 348), and occurred most frequently in migrainous disorders not fulfilling the criteria (25 of 56, 44.6%). This group differed significantly from the other migraine conditions for longer pain duration ( P <0.02) and less frequent nausea, vomiting, photophobia, phonophobia ( P <0.0001), and aggravation by physical activity ( P <0.02). With these characteristics, this group resembled cervicogenic headache. However, in none of these patients was pain triggered by head or neck movements, and the frequency of head or neck trauma did not differ from other headaches. A more precise definition of clinical criteria for cervicogenic headache vs migraine is, therefore, required.     

The International Headache Society (IHS) Headache Classification as applied to a headache clinic population

Four hundred patients attending a headache clinic were classified using the IHS criteria. The majority required more than two, often three or four, diagnoses. Even though migraine was the most common diagnosis, only 1/4 of those with a migraine diagnosis had it as the only diagnosis. Seventy-five percent of migraine patients had coexistent chronic tension-type headache (CTTH), drug-induced headache or both. Ninety-six percent of patients diagnosed as having migraine with aura also suffered from migraine without aura. More than 1/3 of patients (37.7%) attending the clinic suffered from chronic daily headache (CDH) (chronic cluster headache excluded), which is not included as a separate entity in the IHS classification. Pure CTTH formed only a small minority of CDH, whereas 86.6% of CDH had migraine as one of the diagnoses. Drug-induced headache was a prominent second or third diagnosis. The advantages and disadvantages of multiple verses single diagnosis in CDH and the need to recognize the natural history of headache disorders in the classification are discussed.     

Inpatient Treatment of Status Migraine With Dihydroergotamine in Children and Adolescents

Objective.— To assess the effectiveness of aggressive therapy of status migraine in children and adolescents.
Background.— Inpatient management of pediatric status migraine and intractable headache is limited because of a lack of studies and guidelines. Adult treatment is often based on anecdotal experience, although a few controlled studies have been reported. Added to that is the discomfort of general pediatricians and neurologists in using available effective treatments in pediatric patients (such as dihydroergotamine: DHE).
Methods.— Charts of all patients admitted to the neurology service, at Cincinnati Children's Hospital Medical Center—Department of Neurology, for inpatient treatment for intractable headache/status migraine over a 6-week period were reviewed. Demographics, evaluation, diagnosis, and treatment used were tabulated. Data on the effectiveness of the treatments provided were evaluated. Thirty-two total consecutive charts were retrospectively reviewed during that period.
Results.— Upon discharge, 74.4% of the patients were headache-free. The mean severity of the pain upon discharge was 1.02 ± 2.22 (using the 0-10 pain scale).
Conclusion.— From our review, DHE is very effective in treating and aborting an episode of status migraine and should be offered to children and adolescent patients who have failed their usual abortive therapy to prevent further severe disability that mainly affects their schooling and social activities.     

Menstrual Migraine in Adolescents

Objective.— To characterize menstrually associated headaches and migraine in adolescent girls and identify any developmental and pubertal changes. Background.— Headache and migraine is a common problem in adolescents with a transition to adult patterns. One pattern of adult migraine is the menstrual association in a significant number of women. Methods.— A retrospective analysis was performed of characteristics of adolescent's headaches including association with menstrual pattern. A detailed analysis of the patient‐ and parent‐reported headache characteristics and patterns of longitudinal change with development and puberty was reviewed, including timing of headache with age and menstrual period and progression of these events over the adolescence. Results.— Of the 896 girls between 9 and 18 years old reviewed at initial evaluation, 331 (50.3% of menarchal girls and 36.9% of all girls) report experiencing headaches with their menstrual period. Of those reporting a menstrual pattern, 63.6% reported migraines starting between day ?2 and +3 of their menstrual period start. Girls with menstrual migraine reported increased associated symptoms compared with girls without menstrual migraine. There was no difference in disability between girls with a menstrual pattern and those without a menstrual pattern (t = 1.64; P = .10). Additionally, 160 girls reported a monthly pattern to their headaches prior to beginning menstruation, suggestive of a menstrually related migraine pattern prior to menstruation. Conclusions.— The pattern of menstrual association begins to become apparent during adolescence. Once the menstrual pattern has developed, this association is stable. Early identification of this pattern has potential long‐term benefit for improved lifelong outcome.     

Migraine headaches in adolescents: a five-year follow-up study

BACKGROUND AND OBJECTIVES: Longitudinal studies of juvenile migraine are very few. We investigated the prevalence and evolution over 5 years of migraine without aura (MWOA) and migraineous disorder (MD) in an adolescent population. METHODS: Sixty-four subjects (34 girls and 30 boys, mean age 17.3+/-1.1 years) out of 80 selected in our 1989 epidemiological survey were included in the study. The diagnostic criteria of the International Headache Society were used in both studies. RESULTS: Thirty-two of 64 subjects (50%) had MWAO, 18 (28.1%) had MD, and 14 (21.9%) had headache not classifiable (HnC). Our results show that MWOA persisted in 56.2%, converted to MD or HnC in 9.4% and 3.1% of cases, respectively, changed to episodic tension-type headache (ETTH) in 12.5%, and remitted in 18.8%. MD persisted in 11.1%, converted to MWOA or HnC in 27.8% and 5.5% of cases, respectively, changed to ETTH in 11.1%, and remitted in 44.5%. HnC persisted in 14.3%, converted to MD or MWOA in 21.4% and 14.3% of cases, respectively, changed to ETTH in 14.3%, and remitted in 35.7%. CONCLUSIONS: Our data indicate that juvenile-onset MWOA and MD may change in character over time, generally with a favorable prognosis.     

Clinical characteristics of tension-type headache and migraine in adolescents: a student-based study

BACKGROUND AND OBJECTIVES: Adolescent headaches, particularly migraine, might present with different features from adult headaches. The objectives of this study were to investigate the characteristics of tension-type headache and migraine, to find the sensitivity and specificity of the diagnostic criteria of the IHS classification according to age and gender. METHODS: A multistep, stratified, cluster sampling method was used for subject selection. The estimated sample size was 2387. The study was conducted in two phases: the questionnaire and the face to face interview phases. During the semistructured interview, a clinical diagnosis has been made and clinical characteristics have been recorded. RESULTS: All headaches fulfilled the criteria of duration. The most common feature of migraine was moderate to severe (92.4%), pulsating pain (79.2%). For ETTH, bilateral localization (91.3%) and mild to moderate pain intensity (90.6%) were the most common features. Younger adolescents showed mixed headache characteristics. Highest sensitivities for migraine were duration (100%), moderate to severe pain (92.4%), and pulsating quality of pain (79.2%). Vomiting, trigger factors food and alcohol had a high specificity for migraine. CONCLUSIONS: Our data strongly support continuum hypothesis. In early adolescence headaches might present with mixed headache characteristics. Age and gender have some influence on headache characteristics, particularly on migraine. The sensitivity and specificity of case definition criteria of ICHD-2 for adolescent migraine is moderate and need to be reconsidered.     

ACE Inhibitors for Prophylaxis of Migraine Headaches

Seventeen patients with migraine headaches, occurring at least twice a month, were successfully treated with an ACE inhibitor for prophylaxis. Most were given enalapril, some used lisinopril. Duration of treatment ranged from 3 months to 3 years. Side effects were generally not noted. Cough occurred in four patients. The mechanism of action is unknown. The lack of side effects and the presence of clearly sustained benefit in this small group of migraineurs should prompt further study and use of this class of drugs for prophylaxis.     

Evaluating the IHS criteria for cluster headache--a comparison between patients meeting all criteria and patients failing one criterion

Cluster headache (CH) is diagnosed according to criteria of the International Headache Society (IHS), but, in clinical practice, these criteria seem too restrictive. As part of a nation-wide study, we identified a group of patients who met all criteria minus one (IHS-CH-1), and assessed in which way they differed from CH patients meeting all criteria (IHS-CH). We performed a nation-wide questionnaire study for CH and CH-like syndromes, including questions based on the IHS criteria, and additional features such as restlessness during attacks, nocturnal onset of attacks, circadian rhythmicity of attacks and response to treatment. IHS-CH and IHS-CH-1 patients were compared. Of 1452 responders to two questionnaires, 1163 were IHS-CH and 289 were IHS-CH-1. The majority of the IHS-CH-1 patients were classified as such because their attacks exceeded 3 h (64%, median attack duration: 5 h), or came in a frequency of less than 1 per 2 days (16%). Age at onset was similar between the groups. The male to female ratio was 3.7 : 1 in the IHS-CH group and around 1.6 : 1 in the IHS-CH-1 groups (P < 0.005). Patients with attacks exceeding 3 h less often reported a circadian rhythmicity (IHS-CH-1: 49%, IHS-CH: 64%), episodic periodicity (IHS-CH-1: 65%, IHS-CH: 78%), nocturnal attacks (IHS-CH-1: 67%, IHS-CH: 78%), smoking (IHS-CH-1: 90%, IHS-CH: 80%) and restlessness during attacks (IHS-CH-1: 64%, IHS-CH: 76%) than IHS-CH patients (P < 0.005). Photo- or phono-phobia (IHS-CH-1: 67%, IHS-CH: 54%) and nausea (IHS-CH-1: 38%, IHS-CH: 27%) were more frequently reported by patients who reported to have attacks exceeding 3 h (P < 0.005). Similar proportions reported effect of verapamil on their attacks (IHS-CH-1: 54%, IHS-CH 61%). We conclude that average attack duration exceeding 3 h was frequently the reason for not fulfilling IHS CH criteria. Symptoms often accompanying CH such as restlessness, nocturnal attacks and an episodic attack pattern were relatively frequently present in IHS-CH-1 patients with longer attacks. These patients may therefore be diagnosed with CH. Attack frequency may not be a useful criterion for the diagnosis of CH. The upper limit of 3 h should be increased in future diagnostic criteria.     

The Evolution of Chronic Migraine: Classification and Nomenclature

After nearly 3 decades of debate, the headache community still lacks globally accepted criteria for chronic migraine . This review summarizes the evolution of chronic migraine nomenclature and criteria. We concluded that although there are discrepancies in the currently proposed criteria, there is a significant amount of overlap with previously used classifications such that they all appear to describe the same subset of highly burdened migraine patients. In order to continue to understand the natural history of chronic migraine , address the unmet medical need, and develop effective therapies, field experts and physicians must have a classification that is well understood and accepted by the broader clinical community. It is our view that of the currently established classifications, the Silberstein and Lipton revised criteria for transformed migraine are the most applicable to daily clinical practice and field research.     

Migraine MLT-Down: An Unusual Presentation of Migraine in Patients With Aspartame-Triggered Headaches

Aspartame, an artificial sweetener added to many foods and beverages, may trigger headaches in susceptible individuals. We report two patients with aspartame-triggered attacks in whom the use of an aspartame-containing acute medication (Maxalt-MLT) worsened an ongoing attack of migraine.
