Description and Validation of an Italian ICHD‐II‐Based Questionnaire for Use in Epidemiological Research

In the absence of biological markers, the diagnosis of primary headache in epidemiological studies rests on clinical findings, as reported through ad-hoc interviews. The aim of this study was to validate a specially designed headache questionnaire to be administered by a physician for the diagnosis of primary headaches or of probable medication overuse headache in the general population according to the 2004 International Classification of Headache Disorders, 2nd edition (ICHD-II). The questionnaire comprises 76 questions based on the ICHD-II diagnostic criteria for migraine (codes 1.1, 1.2.1, 1.2.2, 1.2.3, 1.5.1, and 1.6), tension-type headache (codes 2.1, 2.2, 2.3, and 2.4), primary stabbing headache (code 4.1), and probable medication-overuse headache (code 8.2.7), as well as on other clinical features (eg, age at onset, relation between headache and pregnancy, etc). The answers to each question could be of the following types: (1) numbers (ie, age at onset); (2) "Yes" or "No" (eg, as in reply to "Do you have nausea during headache?"); and (3) predefined answers (eg, quality of pain). We assessed the validity and reliability of the questionnaire and its sensitivity and specificity for migraine and tension-type headache. The study population consisted of 50 patients (37 women and 13 men) aged 18-76 years (mean, 40.7) seen for the first time on a consecutive basis at the University of Parma Headache Centre. The questionnaire was administered independently by 2 trained physicians (E1 and E2) prior to the visit performed by a headache specialist taken as the gold standard (GS). GS, E1, and E2 were blind to the diagnosis made by each others. If appropriate, more than 1 headache type were considered. When present, we defined the 2 different headache types in the same subject as Diagnosis 1 and Diagnosis 2. Questionnaire-based diagnosis was compared with the diagnosis established by GS. For Diagnosis 1 (n = 50), we found an agreement rate of 98% (K-value: 0.96; 95% confidence interval [CI]: 0.88-1.00) between E1 and GS and between E2 and GS, and of 96% (K-value: 0.91; 95% CI: 0.80-1.00) between E1 and E2. For Diagnosis 2 (n = 24), we found an agreement rate of 83.3% (K-value: 0.80; 95% CI: 0.63-0.98) between E1 and GS, of 62.5% (K-value: 0.62; 95% CI: 0.41-0.82) between E2 and GS, and of 70.8% (K-value: 0.66; 95% CI: 0.45-0.87) between E1 and E2. Sensitivity and specificity were 100% and 93.3%, respectively, for migraine without aura (code 1.1) and 100% for frequent episodic tension-type headache (code 2.2). Our findings support the use of this questionnaire as a valid and reliable tool for diagnosis of headaches in epidemiological studies.

Hypnotic Relaxation Vs Amitriptyline for Tension‐Type Headache: Let the Patient Choose

Although both pharmacological and behavioral interventions may relieve tension-type headache, data are lacking regarding treatment preference, long-term patient compliance, and feasibility of behavioral intervention in a standard neurological outpatient clinic setting. To describe patient choice, long-term compliance, and clinical outcome in a neurological clinic setting where patients are given the choice of the approach they wish to pursue. Patients presenting to the headache clinic with a diagnosis of tension-type headache that justified prophylactic therapy (frequent episodic tension-type headache or chronic tension-type headache) were given the choice of amitriptyline (AMT) treatment or hypnotic relaxation (HR), and were treated accordingly. Patients were given the option to cross-over to the other treatment group at each visit. HR was performed during standard length neurology clinic appointments by a neurologist trained to perform hypnosis (Y.E.). Follow-up interviews were performed between 6 and 12 months following treatment initiation to evaluate patient compliance, changes in headache frequency or severity, and quality-of-life parameters. Ninety-eight patients were enrolled, 92 agreed to receive prophylactic therapy of some kind. Fifty-three (57.6%) patients chose HR of which 36 (67.9%) actually initiated this treatment, while 39 (42.4%) chose pharmacological therapy with AMT of which 25 (64.1%) patients actually initiated therapy. Patients with greater analgesic use were more likely to opt for AMT (P= .0002). Eleven of the patients initially choosing AMT and 2 of the patients initially choosing HR crossed over to the other group. Seventy-four percent of the patients in the HR group and 58% of patients in the AMT group had a 50% reduction in the frequency of headaches (P= .16). Long-term adherence to treatment with HR exceeded that of AMT. At the end of the study period, 26 of 47 patients who tried HR compared with 10 of 27 who tried AMT continued receiving their initial treatment. HR treatment was a more popular choice among patients. Patients choosing HR reported greater symptom relief than those choosing AMT and were found to have greater treatment compliance. Patients receiving HR were less likely to change treatments. HR practiced by a neurologist is feasible in a standard neurological outpatient clinic setting; HR training should be considered for neurologists involved in headache treatment.

Computer Animated Relaxation Therapy in Children Between 7 and 13 Years with Tension-Type Headache: A Pilot Study

This pilot study evaluated the effect of computer animated relaxation therapy in children between 7 and 13 years with tension-type headache and the children's experiences with the therapy. The therapy consisted of an uncontrolled nine-session course in modified progressive relaxation therapy assisted by computer animated surface EMG provided from the trapezius muscles and with the physiotherapist as a participant observer. Outcome measures were (a) headache frequency and intensity, (b) pericranial tenderness, (c) tension patterns, and (d) evaluations assessed at baseline and at 3 months follow up. Nine children, mean age 10.9 (SD 1.7) years, diagnosed with frequent episodic or chronic tension-type headache completed the course. The results showed a mean improvement of 45% for headache frequency at 3 months follow up versus baseline and a significant reduction in headache frequency for all participants and in Total Tenderness Score for children with frequent episodic tension-type headache. The children expressed a growing understanding of body reactions and an acquired ability to deactivate and regulate these reactions. Computer animated SEMG seems an applicable learning strategy for young headache sufferers. This study suggests that children below the age of 13 need both the dialog and guidance from a participant observer in order to achieve body awareness.

Salivary cortisol and melatonin levels in children with frequent episodic tension‐type headache do not differ from healthy children

To investigate the differences in cortisol and melatonin concentrations between children with frequent episodic tension-type headache (FETTH) and healthy children. Forty-four children, 12 boys/32 girls (age: 9 ± 2 years) with FETTH associated to peri-cranial tenderness and 44 age- and sex- matched healthy children participated. Both salivary cortisol and melatonin concentrations were collected from non-stimulated saliva following standardized guidelines. A headache diary for 4 weeks was used for collecting intensity, frequency and duration of headache. No significant differences for cortisol (t = -0.431; p = 0.668), and melatonin (z = -1.564; p = 0.118) concentrations and salivary flow rate (z = -1.190; p = 0.234) were found between both groups. No significant effect of age or gender was found. In addition, no significant association between cortisol-melatonin concentrations and between cortisol-melatonin concentrations and headache clinical parameters were found. These results suggest that children with FETTH, at first instance, do not present deficits in the secretion of these cortisol and melatonin. Prospective longitudinal studies are needed to further elucidate the direction of current findings, particularly the synchronism of cortisol and melatonin and the course of the headache.

Novelty in the treatment of episodic tension-type headache

Frequent episodic tension-type headache (ETTH) is a serious medical problem that is primarily due to its high prevalence. Nonsteroidal anti-inflammatory drugs (NSAIDs) whose efficiency is determined by the rapid and complete regression of cephalgia are primarily used to relieve an ETTH attack. One of the ways to enhance the effect of NSAIDs is their combination with agents that accelerate their absorption or potentiate their action, with caffeine in particular; however, the use of combination agents is limited by a risk for drug-induced headache. A step on the road to the design of effective and safe analgesics has been the development of the combination drug Novigan that contains ibuprofen (400 mg) and the spasmolytics pitofenone (5 mg) and fenpiverinium (0.1 mg). Objective: to study the efficacy of Novigan versus ibuprofen 400 mg in relieving an ETTH attack. Subjects and methods. Fifty patients (mean age 37.1±10.9 years) with frequent ETTH that met the criteria of the International Classification of Headache Disorders, 2nd Edition, were examined. For relief of ETTH attacks, 30 patients used Novigan and 20 took ibuprofen in a dose of 400 mg. Results. There was a significant reduction in the intensity of cephalgia 49.9±35.8 and 68.2±45.9 min after drug administration in the Novigan and ibuprofen 400 mg groups, respectively (p = 0.007). The proportion of respondents was higher in the Novigan group (73.3%) than that in the ibuprofen 400 mg group (60%), which is close to the statistically significant difference (p = 0.085). The efficacy predictors were less pain intensity (p < 0.001) and a shorter time after onset (p < 0.001) in the ibuprofen 400 mg group at administration of the drug and only less pain intensity in the Novigan group at that moment (p = 0.07). Conclusion. Novigan is a combination analgesic that rapidly and effectively relieves an ETTH attack, including that of high intensity, as well as extended ETTH attack.

Central Pain Modulation and Scalp Tenderness in Frequent Episodic Tension‐Type Headache

To determine whether the inhibitory effect of acute limb pain on pain to mechanical stimulation of the forehead is compromised in individuals with frequent episodes of tension-type headache. Central pain modulation processes are disrupted in patients with chronic tension-type headache. This deficit in pain modulation might be a predisposing characteristic that increases vulnerability to tension-type headache and to symptoms such as scalp tenderness, or could be a feature that develops secondarily during attacks and that persists for a few days afterward. To distinguish between these 2 possibilities in the present study, inhibitory pain control was investigated in participants with episodic rather than chronic tension-type headache. Pressure-pain thresholds and sensitivity to sharpness in the forehead were measured in 34 individuals with 1-10 episodes of tension-type headache per month and in 32 controls before and after immersion of their hand in painfully cold water. Before the cold pressor test, pressure-pain thresholds and sensitivity to the sharp stimulus were similar in both groups. Mild headache developed and pressure-pain thresholds in the forehead decreased from 631 ± 178 g to 579 ± 196 g (mean ± SD) after the cold water immersion in the episodic tension-type headache group (P < .05). However, sharpness ratings did not change (mean rating 3.2 ± 1.4 on a 0-10 scale). In contrast, headache did not develop, pressure-pain thresholds did not change, and sharpness ratings decreased from 3.0 ± 1.3 to 2.3 ± 1.1 after the immersion in controls (P < .01). These findings suggest that endogenous pain modulation processes are compromised in individuals with frequent episodic tension-type headache. This deficit could increase vulnerability to scalp tenderness and recurrent episodes of headache.

Differences in cervical musculoskeletal impairment between episodic and chronic tension-type headache

Tension-type headache (TTH) is a headache in which musculoskeletal impairments of the craniocervical region may play an important role in its pathogenesis. We investigated the presence of myofascial, postural and mechanical abnormalities in patients with frequent episodic and chronic tension-type headache (ETTH and CTTH, respectively). The study population consisted of 36 patients with ETTH, 23 with CTTH and 42 control subjects. Myofascial trigger points (MTrPs) were identified in the upper trapezius, sternocleidomastoid, temporalis and suboccipital muscles. Sagittal C7-tragus angle was measured to evaluate flexor head posture (FHP), and neck mobility was assessed using an inclinometer. Only active MTrPs were significantly different between the ETTH and CTTH groups (p < .001). Patients with CTTH showed a larger sagittal C7-tragus angle (p = .011), that is, greater FHP and restricted neck mobility for both rotations compared to controls (p < .001). Although active MTrPs were correlated with the frequency and duration of headache, no correlations were observed for FHP or neck mobility. Active MTrPs in the craniocervical region contribute to triggering or maintenance of TTH and posture or neck mobility may be a result of chronic headache.

Generalized Mechanical Nerve Pain Hypersensitivity in Children With Episodic Tension-type Headache

The objective of this study was to analyze the presence of generalized pressure pain hypersensitivity over nerve tissues in trigeminal and nontrigeminal regions in children with frequent episodic tension-type headache (FETTH). Thirty children, 7 boys and 23 girls (mean age: 8.8 +/- 1.7 years) with FETTH and 50 age- and gender-matched healthy children (14 boys, 36 girls; mean age: 8.5 +/- 2.1 years; P = .743) were recruited. Pressure pain thresholds (PPTs) were bilaterally assessed over supra-orbital (V1), infra-orbital (V2), mental (V3), median (C5), radial (C6), and ulnar (C7) nerves by an assessor who was blinded to the patient's condition. The analysis of variance showed that PPT levels were significantly bilaterally decreased over both trigeminal (supra-orbital, infra-orbital, and mental) and nontrigeminal (median, ulnar, and radial) nerves in children with FETTH as compared with control subjects (all sites, P < .001). There was a greater magnitude of PPT decrease within trigeminal nerves as compared with nontrigeminal nerves (P < .03). PPTs over infra-orbital (r(s) = -0.4, P < .05) and radial (r(s) = -0.5, P < .01) nerves were negatively correlated with the duration of headache attacks (P < .05). Our study revealed bilateral and generalized pressure hypersensitivity over both trigeminal and nontrigeminal nerves in children with FETTH. Diffuse hypersensitivity of peripheral nerves evidences the presence of hyperexcitability of the central nervous system in children with FETTH.

Pain sensitivity in children with frequent episodic tension type headache

In the current issue of Cephalalgia, Fernandezde-las-Penas and colleagues report decreased pressure pain thresholds in children with frequent episodic tension-type headache (TTH). The degree of pain hypersensitivity was similar at pericranial and extracranial locations. The finding of wide-spread pressure pain hypersensitivity, also at non-symptomatic locations, suggests that the central nervous system is sensitised in these children. The study is important because, for the first time, it examines wide-spread pressure pain sensitivity in children with frequent episodic TTH. Only 25 children with frequent episodic TTH were investigated. The findings should, therefore, be confirmed in other studies, and also other types of nociceptive stimuli should be investigated. However, the study has several strengths: (i) the diagnosis was ensured though headache diaries; (ii) a well-defined group was investigated, i.e. only children with frequent headaches (8–14 days per month); and (iii) investigations were performed in a blinded design. The results of Fernandez-de-las-Penas and colleagues are in line with the findings from numerous studies performed in the last two decades in adults with TTH (1). These studies initially demonstrated that patients with episodic TTH had increased tenderness of their pericranial muscles and normal general pain sensitivity, while patients with chronic TTH had both increased pericranial tenderness and a generalised, wide-spread pain hypersensitivity (2). After the division of episodic TTH into infrequent and frequent subtypes in the second edition of the International Classification of Headache Disorders in 2004 (3), several studies have demonstrated also that patients with frequent episodic TTH have a generalised pain hypersensitivity (4,5). The studies of pain sensitivity in TTH led to the hypothesis that nociceptive input from pericranial myofascial tissues is important for the development of single episodes of TTH, while continuous nociceptive input from these structures may lead to increased excitability of nociceptive pathways and impaired pain inhibition in the central nervous system and, thereby, to headache chronification (2). This has been supported not only by a number of cross-sectional pain studies (1), but also by imaging studies (6), neurophysiological studies (7–9) and pharmacological studies (10,11). Most importantly, a recent longitudinal 12-year follow-up study (12) demonstrated that subjects who developed episodic TTH had increased pericranial myofascial tenderness but normal general pain sensitivity at follow-up, whereas subjects who developed chronic TTH had normal pain sensitivity at baseline but developed increased central pain sensitivity at follow-up. The investigators concluded that increased pain sensitivity is a consequence of frequent TTH, not a risk factor, and that central sensitisation plays an important role for the chronification of TTH (12). The present study by Fernandez-de-las-Penas and colleagues suggests that central sensitisation can occur already in childhood and underlines the need for further research into the mechanisms responsible for headache chronification. Two major targets for future treatment strategies should be to: (i) identify the source of peripheral nociception in order to prevent the development of central sensitization and, thereby, the conversion of episodic into chronic TTH; and (ii) reduce established central sensitisation.

Bilateral, wide-spread, mechanical pain sensitivity in children with frequent episodic tension-type headache suggesting impairment in central nociceptive processing

The aim was to investigate bilateral, wide-spread pressure pain hyperalgesia in symptomatic (trigeminocervical) and non-symptomatic (pain-free distant) regions in children with frequent episodic tension-type headache (FETTH). Twenty-five children, 6 boys and 19 girls (mean age, 8.9 +/- 1.8 years) with FETTH and 50 age- and sex-matched healthy children (12 boys, 38 girls; mean age: 8.8 +/- 1.7 years) were recruited. Pressure pain thresholds (PPTs) were bilaterally assessed over temporalis muscle, upper trapezius muscle, second metacarpal and tibialis anterior muscles in a blinded design. The results showed that PPT levels were significantly decreased bilaterally over the temporalis, upper trapezius and tibialis muscles, and the second metacarpal in children with FETTH as compared to controls (all sites, P < 0.001). No significant differences in the magnitude of PPT decrease between the upper trapezius muscle, second metacarpal and tibialis anterior muscles were found. PPT over both upper trapezius muscles were negatively correlated with the history and intensity of headache (r(s) = -0.415; P = 0.045). The findings revealed bilateral, wide-spread pressure pain hypersensitivity in children with FETTH suggesting that wide-spread central sensitisation is involved in children with this headache pain condition.

Headache characteristics and chronification of migraine and tension-type headache: A population-based study

Migraine and tension-type headache (TTH) can increase in frequency and transform from episodic to chronic forms. The process of transformation of these primary headaches is complex and involves multiple risk factors. In this cross-sectional and longitudinal population study, we aimed to investigate the relation of clinical characteristics of primary headaches to poor outcome: new-onset or persistent chronic headache (> or =180 days/year). Individuals who had migraine + / - TTH and those who had pure TTH were studied separately. Of 740 individuals who entered this study in 1989, 673 were eligible for follow-up in 2001, and a total of 549 individuals participated in the follow-up study. At baseline in 1989, no difference was found between episodic and chronic migraine headache ( + / - TTH). Duration of headache episodes >72 hours (p = .002) was associated with pure chronic TTH at baseline in 1989 whereas aggravation of headache by physical activity (p = .045) was associated with pure frequent episodic TTH. Of 64 subjects with migraine + / - TTH, 12 had a poor outcome in 2001. For pure TTH, of 116 subjects at baseline, 11 had a poor outcome in 2001. Using multivariate logistic regression analysis with adjustment for medication overuse and use of preventive medications, poor outcome of migraine + / - TTH tended to be associated with a baseline pulsating quality and severe intensity of migraine, photophobia and phonophobia, as well as longer duration of an individual headache attack. For pure TTH, unilateral headache, nausea and individual headache attack duration greater than 72 hours was associated with poor outcome. Pooled data univariate analysis revealed that nausea, daily use of acute headache medications, use of headache preventive medications and coexistent headaches were significant predictors of chronic headache in 2001(p<.05). In conclusion, our study demonstrates that certain clinical characteristics of headaches are associated with poor outcome but alone may not predict the chronification of migraine or TTH.

Asociación de puntos gatillo miofasciales en la cefalea tensional crónica y episódica

Objective To analyze the data from two of our studies in order to compare the association of myofascial trigger points (TrPs) in patients with chronic (CTTH) and frequent episodic tension type headache (ETTH). Material and methods Twenty-five patients with CTTH, 15 subjects with frequent ETTH, and 25 healthy controls (HC) were included. A headache diary was kept for 4 weeks to record the pain history. A blinded assessor examined all the participants in search for TrPs in the trapezius, sternocleidomastoid and temporalis muscles. TrPs were diagnosed according to the following criteria: 1, presence of a taut band within the muscle; 2, presence of a hypersensitive spot in the taut band; 3, local twitch response elicited by snapping palpation, and 4, referred pain elicited by palpation of the TrP. TrPs that evoked a familiar pain were considered active, and those that evoked a non-familiar pain were considered latent. Results Patients showed a greater number of myofascial TrPs compared to controls (F=33.44; P<0.001). The presence of latent TrPs was not significantly different between groups, but active muscle TrPs were only present in patients. The distribution of muscle TrPs (either active or latent) was similar in both groups of patients (0.45<OR<1.5). The total number of TrPs in the analyzed muscles did not show any relationship with the headache parameters. Conclusions Patients with CTTH and frequent ETTH show TrPs in the cranio-cervical muscles in a similar proportion. Tension-type headache may at least partly be explained by the referred pain originated in TrPs of the cranio-cervical muscles.

Medication‐Overuse Headache and Personality: A Controlled Study by Means of the MMPI‐2

The main aim of this study involves comparing the personality profiles of patients with medication-overuse headache (MOH) and episodic headaches, in order to elucidate the role of personality characteristics, according to one of the most widely used and validated personality assessment tool: Minnesota Multiphasic Personality Inventory (MMPI-2). Many studies have assessed the personality of headache patients by means of MMPI-2 only using clinical and content scales. In this study the supplementary scales were also used as they evaluate different aspects of personality, particularly broad personality characteristics, generalized emotional distress and behavioral dyscontrol. We recruited 219 subjects (151 women and 68 men) who were grouped in the following categories: MOH group (n = 82); episodic headache group (n = 82; 58 migraine aura; 6 migraine with aura; 6 frequent episodic tension-type headache; 12 migraine+infrequent episodic tension-type headache) and 1 group of 55 healthy controls. MMPI-2 was employed. Data were computed with one-way anova and post hoc analyses. Medication-overuse headache and episodic headache patients (EH) showed a very similar pattern, differentiating each other only in the Hypochondriasis (Hs) (P = .007; MOH: mean 14.18 [SD 5.53]; EH: mean 11.93 [SD 5.88] and Health Concerns [HEA]) (P = .005; MOH: mean 14.06 [SD 5.38]; EH: mean 11.81 [SD 5.59]) scales. Surprisingly, no differences were found between the 3 groups in the scales measuring dependence-related behavior such as Addiction Potential Scale (Aps) and Addiction Admission Scale (Aas). MOH and episodic headache patients scored significantly higher in the so-called neurotic scales Hs (P < .0001; MOH: mean 14.18 [SD 5.53]; EH: mean 11.93 [SD 5.88]; mean 5.91 [SD 3.57]), Depression (D) (P < .0001; MOH: mean 26.44 [SD 7.01]; EH: mean 26.09 [SD 5.85]; mean 21.47 [SD 4.90]), and Hysteria (Hy) (P < .0001; MOH: mean 27.33 [SD 5.51]; EH: mean 26.81 [SD 5.68]; mean 21.95 [3.85]) and in many other scales such as Paranoia (Pa), Psychasthenia (Pt), Schizophrenia (Sc) while they scored significantly lower on Ego Strength (Es) and Dominance (Do) scales when compared with controls. Patients with MOH and episodic headache showed very similar patterns, differentiating only in the Hypochondriasis and Health Concerns scales. Surprisingly, there were no significant differences in the scores of the scales measuring dependence-related behavior. The clinical role of MMPI-2 in discriminating MOH patients with dependency from drugs is discussed, in order to implement a complete tests' battery for headache patients' assessment.

Tension-Type Headache in Children: The Cinderella of Headache Disorders!

Tension-type headache (TTH) may be as common a headache disorder as migraine in children and adolescents. TTH has a neurobiological basis with genetic and environmental factors making variable contributions to the different sub-types. The diagnostic criteria for TTH in the second edition of the "International Classification of Headache Disorders" appear to be applicable to children. Anxiety and mood disorders may be co-morbid with frequent episodic and chronic TTH. Psychosocial stressors play an important role in precipitating and maintaining TTH. Hence, a biopsychosocial approach should be adopted for care. Standardized histories and examinations together with prospective headache diaries are the foundations for good management; attention to 'red flags' will help identify secondary causes that present with headache similar to TT. There are no randomized controlled drug trials for the treatment of TTH. Relaxation and cognitive behavioral therapies are effective. TTH in children and adolescents warrants greater recognition from the clinician and scientist. Studies focusing on TTH are overdue.

Commentary on the Cochrane Review of Acupuncture for Tension-Type Headache

information on patients, interventions, methods and results; and assessed risk of bias and quality of the acupuncture intervention. Outcomes extracted included response (at least 50% reduction of headache frequency; outcome of primary interest), headache days, pain intensity and analgesic use. Main Results: Eleven trials with 2317 participants (median 62, range 10 to 1265) met the inclusion criteria. Two large trials compared acupuncture to treatment of acuteheadachesorroutinecareonly.Both found statistically significant and clinically relevant short-term (up to three months) benefits of acupuncture over control for response, number of headache days and pain intensity. Long-term effects (beyond three months) were not investigated. Six trials compared acupuncture with a sham acupuncture intervention, and five of the six provided data for metaanalyses. Small but statistically significant benefits of acupuncture over sham were found for response as well as for several other outcomes. Three of the four trials comparing acupuncture with physiotherapy, massage or relaxation had important methodological or reporting shortcomings. Their findings are difficult to interpret,butcollectivelysuggestslightlybetter results for some outcomes in the control groups. Conclusions: In the previous version of this review, evidence in support of acupuncture for tension-type headache was considered insufficient. Now, with six additional trials, the authors conclude that acupuncture could be a valuable nonpharmacological tool in patients with frequent episodic or chronic tension-type headaches.

Pharmacotherapy and Lifestyle Interventions for Tension-Type Headaches

The objective of this review was to evaluate the efficacy of pharmacotherapy and lifestyle interventions for tension-type headaches. Literature was obtained through a MEDLINE (1966 to April 2008) search and a bibliographic review of published articles. Key terms searched included tension-type headaches, chronic tension-type headaches, pharmacotherapy, and lifestyle therapy. The search was further limited to the English language. Tension-type headaches are the most common and least studied primary headache disorder. These headaches are characterized by mild to moderate bilateral pain that is described as dull, aching, and bandlike. Episodic tension-type headaches may be treated with mild analgesics such as nonsteroidal anti-inflammatory drugs (NSAIDs) and acetaminophen; although treatment should be individualized, data suggest that NSAIDs may be considered first line. Chronic and frequent episodic tension-type headaches often require prophylactic therapy. Although tricyclic antidepressants are considered the drugs of choice for chronic tension-type headaches, preliminary trials with venlafaxine, mirtazapine, tizanidine, and topiramate have shown promise. Lifestyle interventions such as physical therapy, behavioral therapy, and acupuncture are often employed, despite the lack of sound clinical evidence to support their use. Preliminary data support the combination of a tricyclic antidepressant and behavioral therapy for chronic tension-type headache.

Influence of social factors, clinical characteristics and comormidities on the health related quality of life in patients with tension type headaches

Here we present the results of our study of the influence of clinical and social parameters as well as co-morbidities (as anxiety, depression, sleep disturbances) on the health related quality of life of 95patients with the most often met primary cephalgias — tension type headache. We used MOS-SF36 (Medical Outcomes Study Short Form-36) as the main instrument to measure health related quality of life. Significant influence of anxiety and depression on the quality of life in patients with both frequent episodic and chronic tension type headache was reported. Anxiety in these patients was mostly associated with psychic health, general health and vitality. In patients with chronic tension type headaches depression was associated with physical functioning; in those with frequent episodic tension type headaches — with social functioning and role functioning due to emotional sate.

Clinical Features of Primary Headache in Children: A Multicentre Hospital-Based Study in France

The aim of this study was to evaluate the concordance between clinical diagnosis and the International Classification of Headache Disorders, 2nd edn (ICHD-II) in children and adolescents with primary headaches. This 6-month prospective multicentre study of 486 patients (mean 9.8 +/- 3.1 years; 52.6% girls) assessed the headache features through a structured questionnaire. In 398 patients with a single type of headache, headaches were bilateral (78.1%), frontal (62.4%), pulsatile (56.1%), with associated symptoms in 84.4%. The most frequently assigned diagnoses were migraine without aura (50.8%), probable migraine (14.1%), migraine with aura (11.1%) and frequent episodic tension-type headache (7.5%). For most of the diagnostic categories, the consistency of the investigator's diagnosis with the ICHD-II criteria was good (kappa > 0.6 and < or = 0.8) or excellent (kappa > 0.8). We conclude that migraine was predominant with regard to headache diagnoses repartition and that the ICHD-II seems usable in practice for evaluation of primary headache in French children and adolescents.

Restless legs syndrome and primary headaches: a clinical study

Based on recent data about the association between restless legs syndrome (RLS) and migraine, we performed an observational study on the occurrence of RLS in patients affected by primary headaches. Two hundred headache patients (149 women and 51 men) and 120 (90 women and 30 men) sex-and age-matched control subjects were included. In the headache group, migraine without aura (MO) was the most represented headache type (n=114), followed by the "mixed" group (n=40) with MO, migraine with aura (MA) and frequent episodic tension-type headache (ETTH) in various combinations, and by ETTH alone (n=22). The remaining patients suffered from MA alone (n=10 MA), episodic cluster headache (ECH n=12) and primary stabbing headache (n=2). RLS frequency was significantly higher in headache patients than in control subjects (22.4% vs. 8.3, p=0.002) independently of sex, although with a female preponderance (84%) in both groups. More than 60% (n=27) of RLS patients were affected by MO and 30% (n=13) by a combination of two headache types (p> or =0.001), with a very low frequency of RLS for the other types of headache. No RLS patient had ECH. No statistical differences were observed among clinical characteristics of different types of headache in groups with and without RLS. In both headache and control groups, higher scores for depression and anxiety were more frequent in subjects with RLS compared with those without RLS. Furthermore, headache patients with RLS reported sleep disturbances more frequently compared to those without RLS (50.0% vs. 32.7%; p<0.0001) and showed a normal or underweight body mass index. Our data seem to confirm the existence of an association between RLS and primary headaches, particularly with migraine, as already demonstrated. The absence of RLS in ECH patients is very interesting. Many pathogenetic considerations about links between RLS and primary headaches could be given, the most fitting involving dopamine and melatonin.

Increased pain sensitivity is not a risk factor but a consequence of frequent headache: A population-based follow-up study

Altered pain sensitivity is believed to play an important role for chronification of headache. It has however mainly been evaluated in highly selected patients from headache clinics and never in longitudinal studies. The present study is a 12-year follow-up of a population-based study of primary headache disorders and pain perception, combining a diagnostic headache interview with examination of muscle tenderness and measurement of pressure pain thresholds in 1000 subjects drawn randomly from the general population in Denmark. The aim of the study was to explore the cause–effect relationship between the increased pain sensitivity and the development of headache. The pressure pain thresholds were normal at baseline but had decreased at follow-up in subjects who developed chronic tension-type headache over the 12-year period ( p = 0.025). In subjects who developed frequent episodic tension-type headache the tenderness was normal at baseline but had increased at follow-up ( p < 0.01) while the pain thresholds were normal both at baseline and at follow-up. The findings demonstrate that increased pain sensitivity is a consequence of frequent tension-type headache, not a risk factor, and support that central sensitization plays an important role for the chronification of tension-type headache.
