PO-04 | Mindfulness-based behavioral intervention for adolescents with high-frequency primary headaches: feasibility of a prospective multicenter study

The study aimed to test the reliability of a semi-structured telephone interview for the classification of headache disorders according to the ICHD-3. Questionnaire-based screening tools are often optimized for single primary headache diagnoses [e.g., migraine (MIG) and tension headache (TTH)] and therefore insufficiently represent the diagnostic precision of the ICHD-3, which limits epidemiological research of rare headache disorders. Brief semi-structured telephone interviews could be an effective alternative to improve classification. A patient population representative of different primary and secondary headache disorders (n = 60) was recruited from the outpatient clinic (HSA) of a tertiary care headache center. These patients completed an established population-based questionnaire for the classification of MIG, TTH, or trigeminal autonomic cephalalgia (TAC). In addition, they received a semi-structured telephone interview call from three blinded headache specialists individually. The agreement of diagnoses made either using the questionnaires or interviews with the HSA diagnoses was evaluated. Of the 59 patients (n = 1 dropout), 24% had a second-order and 5% had a third-order headache disorder. The main diagnoses were as follows: frequent primary headaches with 61% MIG, 10% TAC, 9% TTH, and 5% rare primary and 16% secondary headaches. Second-order diagnosis was chronic migraine throughout, and third-order diagnoses were medication overuse headache and TTH. Agreement between main headaches from the HSA was significantly better for the telephone interview than for the questionnaire (questionnaire: κ = 0.330; interview: κ = 0.822; p < 0.001). Second-order diagnoses were not adequately captured by questionnaires, while there was a trend for good agreement with the telephone interview (κ = 0.433; p = 0.074). Headache frequency and psychiatric comorbidities were independent predictors of HSA and telephone interview agreement. Male sex, headache frequency, severity, and depressive disorders were independently predictive for agreement between the questionnaire and HSA. The telephone interview showed high sensitivity (≥71%) and specificity (≥92%) for all primary headache disorders, whereas the questionnaire was below 50% in either sensitivity or specificity. The semi-structured telephone interview appears to be a more reliable tool for accurate diagnosis of headache disorders than self-report questionnaires. This offers the potential to improve epidemiological headache research and care even in underserved areas.

Most primary headaches are classified into a few categories, such as migraine or muscle contraction headache, and patients suffering from these headaches are common. On the other hand, other primary headaches are very rare. In this section entitled "Other primary headaches", eight headaches, including primary stabbing headache, primary cough headache, primary exertional headache, primary headache associated with sexual activity, hypnic headache, primary thunderclap headache, hemicrania continua, and new daily-persistent headache, are described. Some characteristics of other primary headaches are common in symptomatic headaches, such as subarachnoid hemorrhage or arterial dissection. Therefore, careful evaluations including neuroimaging are necessary to exclude organic diseases.

Specific Music Therapy Techniques in the Treatment of Primary Headache Disorders in Adolescents: A Randomized Attention-Placebo-Controlled Trial

To evaluate the possible relationship between sleep disturbances and primary headaches. This prospective study was carried out in a random group of patients with active primary headaches (case group) and a control group. Patients with active primary headaches were further stratified into two groups: patients with migraine and patients with tension-type headache (TTH). Participants were questioned using the following standardized tests: Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Berlin Sleep Apnea Questionnaire (BSAQ), and a custom-made headache questionnaire. The results of the questionnaires were compared among patients with TTH, patients with migraine, and age- and sex-matched controls. Of the 143 participants, 22.4% had TTH, 30.8% were diagnosed with migraine, and 46.9% did not have a diagnosed headache disorder. Patients with TTH were more likely to have insomnia (ISI score > 7) than patients with migraine (75% vs 50%, respectively) or controls (75% vs 37.3%, respectively) (P = .002). Frequency of poor sleep quality (global PSQI score ≥ 6) was significantly highest in the TTH group (87.5%), while the migraine and control groups had better sleep quality (47.7% and 43.3%, respectively) (P = .0001). TTH patients were more likely to have insufficient sleep (sleep efficiency < 85%) (53.1%) than those with migraine (25%) or the control group (29.9%) (P = .025). Patients who suffered from TTH were more likely to have insomnia than patients with migraine or controls. Nearly all patients with TTH had poor sleep quality, which was also observed in approximately half of the individuals in the migraine and control groups. Three-quarters of patients in the TTH group and more than half in the migraine group indicated inadequate sleep as a trigger factor for headache.

It is estimated that 30–80% of the population in Europe and the United States experience frequent and recurrent headaches, the most common of which are tension-type, migraine and cluster headaches. Migraine can also overlap with tension-type headache, which is referred to as vasomotor or mixed headache. According to the 3rd edition of the International Classification of Headache Disorders (ICHD-3 beta), these entities are classified as idiopathic (primary) headaches, where pain is both the essence and the main symptom of the disease. Idiopathic headaches are difficult to diagnose as they differ mainly in intensity. When collecting medical history, the focus should be placed on the duration and location of pain. Therefore, a thorough interview to assess subjective pain intensity is one of the basic elements of the diagnostic workup. Tension-type headache, migraine and cluster headaches are also characterised by specific symptoms, identification of which is essential for the diagnosis. Cluster headache produces the most typical symptoms. Since these types of headaches require different therapeutic strategies, it is necessary to differentiate them. Their treatment requires interdisciplinary cooperation of, among others, dentists, neurologists, and physiotherapists. In this paper, we made an attempt to discuss the pathogenesis, symptoms and differential diagnosis of tension headache, migraine and cluster headache, based on literature review.

Applying the International Classification of Headache Disorders to the Emergency Department: An Assessment of Reproducibility and the Frequency With Which a Unique Diagnosis Can Be Assigned to Every Acute Headache Presentation

Tension-type headache and migraine are the most frequent primary headaches. Diagnosis is based on the patient's history and a normal neurological examination. Most patients with these two headache entities treat headache episodes with over-the-counter analgesics or non-steroidal anti-inflammatory drugs (NSAIDs). There is good scientific evidence from randomised, placebo-controlled trials indicating that aspirin, ibuprofen, ketoprofen, diclofenac and naproxen are effective in tension-type and migraine headache. Paracetamol seems to be less effective. In patients with migraine who do not respond to analgesics or NSAIDs, triptans should be prescribed. Frequent primary headaches should not be treated with frequent intake of analgesics or triptans. In these cases, preventive therapy needs to be implemented.

Tension type headaches: Whether they are primary or secondary headaches?

Background: Headache is one of the most common complaints in children and adolescents and comorbidity rates are very high and the major associated diseases are depression, anxiety, atopic disorders, sleep, and behavioral disorders. In recent years, it has been highlighted that difficulties regulating emotions such as alexithymia have also been associated with diagnosis of somatization.Methods: We carried out a mini review analyzing the relation between alexithymia and primary headache (e.g., migraine and tension type headache) in children and adolescents by synthesizing the relevant studies in the literature on PubMed, PsycINFO, and Google Scholar. Search terms were “alexithymia” combined with the “primary headache,” “migraine,” “tension type headache,” “children,” and “adolescents.”Results: All analyzed studies found higher levels of alexithymia in children and adolescents with headache than control groups but there are different opinions about the relationship between headache and alexithymia. For example, some studies suggest that the association between headache and alexithymia in children may be due to an incomplete development of emotive competency or a general immature cognitive development, instead other studies found a correlation between headache symptoms, insecure attachment, and alexithymia. There seems to be also differences between children with migraine compared to those with tension type headache (TTH).Conclusion: There are some studies on adults suffering from headache or migraine and alexithymia, but there is only a moderate amount of research on pediatric age with different opinions and theories about this relationship. Further studies on children and adolescents are necessary to effectively understand this relationship and to help children to reduce headache and improve emotional consciousness.

To assess whether the biallelic -231 G>A polymorphism of the endothelin type A receptor (EDNRA) gene, previously shown to be a marker of increased risk for developing migraine, has a role in the susceptibility to primary pediatric headache. Several studies suggest that endothelin has a role in migraine. A recent association study has shown that the biallelic -231 G>A polymorphism of the EDNRA gene is associated to migraine in an elderly population. A total of 126 consecutive unrelated pediatric patients affected by primary headache, classified according to the International Headache Society criteria in migraine (migraine with aura, n = 3; migraine without aura, n = 80), and tension-type headache (episodic tension-type headache, n = 36; chronic tension-type headache, n = 7) patients, were recruited to the study. Sixty-seven healthy blood donors were used as a control group. Genomic DNA was extracted from buccal swabs or blood samples and analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) for the above-mentioned polymorphism. Allele and genotype frequencies for primary headache patients were analyzed in comparison with the control group. No significant differences were found in the distribution of the EDNRA -231 G>A polymorphic variant when considering both genotype (migraine chi2 = 2.78, P = .25; tension-type headache chi2 = 3.58, P = .17) and allelic frequencies (migraine chi2 = 1.48, P = .22; tension-type headache chi2 = 0.39, P = .56). Furthermore, no significant genotype-related difference was found in relation to clinical features, such as age at onset, frequency, and length of the attacks. Our study shows that the -231 G>A polymorphism in the EDNRA gene is neither associated with primary juvenile headache nor significantly correlated with main clinical features characteristic of the headache pathology in pediatric settings.

BackgroundLittle is known about the prevalence of primary and secondary headache in clinics in Japan. The aim of this study is to characterize patients with headache in an outpatient unit where primary care physicians are working in Japan.MethodsConsecutive outpatients who newly visited the Department of General Medicine, Asahikawa Medical College Hospital, Asahikawa, Japan between April 2005 and March 2009 were analyzed. Each parameter such as age, sex or diagnosis was investigated.ResultsOut of 4693 patients, 418 patients visited to our department because of headache. Primary headache was found in 167 patients (39.9%). The rate of tension-type headache (TTH) (30.8%) was highest, followed by migraine (9.1%). Approximately 3 times higher rate of migraine was observed in female patients when compared with male patients. In female patients, migraine was observed more frequently in younger patients. On the other hands, TTH was observed in almost all aged patients in males and females, and the rate of TTH peaks between the ages of 40 and 49 years in both sex. The present study also demonstrated that 8.4% of patients who chiefly complained of headache had been diagnosed as depression while 1.7% of remained patients had been diagnosed as depression, indicating 5-times higher rate of depression in patients with headache.ConclusionAll these results suggest that primary headache, especially TTH, is highly observed and depression should be considered in patients with headache in an outpatient clinic where primary care physicians are working in Japan.

Headache, which is the clinical manifestation of intracranial hypertension, is also a clinical ailment in medical practice, as well as one of the main causes of visits in the paediatric age. Determining whether this symptom is secondary or not to a decompensation of the intracranial pressure in children with hydrocephalus is sometimes a challenging task. The aim of this study is to classify the headaches in a population of children with a ventriculoperitoneal bypass valve due to hydrocephalus. We conducted a study of a series of cases with a longitudinal follow-up. 20 children with a ventriculoperitoneal bypass valve owing to hydrocephalus were followed up over a mean period of eight months because they suffered from recurring headaches. All of them answered a questionnaire in order to define the characteristics of their headache. Those who were suspected of suffering from intracranial hypertension were submitted to a cerebral tomography study. In all, we studied 20 patients (eight males and 12 females) with a mean age of 8.6 +/- 2.8 years. Hydrocephalus was secondary to abnormalities in the craniocervical transition and myelomeningocele in all cases. The aetiology of the headache was primary migraine-type headache (14 patients; 70%), and tension-type headache (two patients; 10%). Secondary headaches appeared in four patients (20%) due to acute sinusitis, refraction errors and systemic infection; only one patient had headache due to intracranial hypertension. Migraine predominates as the primary headache in children with bypass valves--a phenomenon that can be explained by its high prevalence in the paediatric population.

In pediatric neurology, tension-type headache (TTH) represents a very common type of primary headache during the pediatric age. Despite the high prevalence of TTH, this diagnosis is often underestimated in childhood, with relevant difficulties in the differential diagnosis of TTH from secondary and primary headache manifestations. Even among primary headaches, a clinical overlap is not so infrequent in children: migraine attacks could present tension headache-like features while tension-type headaches may display migraine-like symptoms as well. Several variables play a role in the complex trajectory of headache evolution, such as hormonal changes during adolescence, triggers and genetic and epigenetic factors. The trajectories and outcomes of juvenile migraine and TTH, as well as the transition of one form to the other, have been investigated in several long-term prospective studies. Thus, the aim of this paper is to review the current literature on the differential diagnosis workout of TTH in pediatrics, the possible outcomes during the developmental age and the appropriate therapeutic strategies. Indeed, TTH represents a challenging diagnostic entity in pediatrics, both from a clinical and a therapeutic point of view, in which early diagnosis and appropriate treatment are recommended.

Existing criteria for the diagnosis of headache do not indicate which clinical features are most important to establish or exclude primary headache diagnoses. To determine the value of history taking in the evaluation of patients with primary headache syndromes. A MEDLINE search of English-language studies published since 1966 and a hand search of bibliographies from retrieved articles. Included studies cited the sensitivity of clinical and historical features for the diagnosis of migraine, tension-type, and cluster headaches. Studies were classified according to their use of the International Headache Society criteria or other criteria as the reference standard for diagnosis. The features most predictive of migraine, when compared with tension-type headache, are nausea, photophobia, phonophobia, and exacerbation by physical activity. Positive likelihood ratios (95% confidence intervals) are 19.2 (15.0-24.5), 5.8 (5.1-6.6), 5.2 (4.5-5.9), and 3.7 (3.4-4.0), respectively. Headache precipitants are present equally in patients with migraine and tension-type headache, with the exception of food triggers, which confer a positive likelihood ratio of 3.6 (2.8-4.6) for the diagnosis of migraine. Visual aurae are present in 84% of patients with migraine with aura. Cluster headache is strictly unilateral, is periorbital in 80% of patients, and lasts less than 1 hour in 54% of patients. The features most predictive of the diagnosis of migraine, when compared with tension-type headache, are nausea, photophobia, phonophobia, exacerbation by physical activity, and an aura. Cluster headache is a distinct clinical syndrome.

Introduction Primary headache is a significant health problem in children as it remarkably negatively affects the child and his/her family. Migraine and tension-type headaches constitute the majority of primary headaches in childhood. Studies regarding adult migraine patients suggest that oxidative stress has a significant role in the pathogenesis. This study aimed to investigate the relationship between primary headache in chidhood and the levels of oxidative stress markers. Materials and methods Pediatric patients diagnosed with primary headache and healthy controls in the pediatric age range were recruited. Data regarding age, gender, height, weight, and body mass index (BMI) were recorded. The levels of ceruloplasmin, lipid hydroperoxide, and prolidase activity were measured in plasma using the ELISA method. Statistical analyses were conducted using the SPSS 11.5 statistical program. A p-value of less than 0.05 was considered significant. Results The study included 76 patients with primary headache and 61 healthy controls. The mean ages of the patients and healthy controls were 14.4±3.2 and 13.6±2.9 years. The patient and control groups were similar in terms of gender distribution (p=0.948), age (p=0.079), and BMI (p=0.196). Migraine accounted for 35.5% (n=27), while tension-type headache accounted for 64.5% (n=49) of the patients. Serum ceruloplasmin (p=0.033), lipid hydroperoxide (p&lt;0.001), and prolidase (p=0.010) levels were higher in patients compared to the control group. Lipid hydroperoxide (p=0.021) and prolidase (p=0.013) levels were higher in migraine patients than in tension-type headache patients, while ceruloplasmin levels were similar between patients with different headache types (p=0.581). Conclusion In this study, oxidative stress markers were shown to be increased in pediatric patients with primary headache. These findings support the hypothesis that patients with primary headaches are exposed to oxidative stress. Future studies may elucidate the role of oxidative stress in the etiopathogenesis of childhood migraine and other headache types.
