Use of the Migraine Disability Assessment Questionnaire in children and adolescents with headache: an Italian pilot study

Examining Acute Symptoms After Sport-Related Concussion in Collegiate Athletes With Preinjury Migraines

OBJECTIVE

To examine whether a personal history of migraines is associated with worse acute symptom burden after sport-related concussion (SRC).

DESIGN

Retrospective cohort study.

SETTING

National Collegiate Athletic Association Division III collegiate programs.

PARTICIPANTS

Collegiate athletes from a prospective concussion surveillance system between 09, 2014, and 01, 2023.

INTERVENTION

Preinjury migraines (yes/no) were self-reported by athletes.

MAIN OUTCOME MEASURES

Post-Concussion Symptom Scale (PCSS) were collected within 3 days postinjury. Mann-Whitney U tests compared total PCSS scores and individual symptom scores between athletes with and without preinjury migraines. Chi-squared tests were used to compare proportions of athletes endorsing individual symptoms (ie, item score ≥1) between 2 groups. Multivariable regression analyzed potential predictors of PCSS scores.

RESULTS

Of 1190 athletes with SRC, 93 (7.8%) reported a preinjury history of migraines. No significant difference in total PCSS scores was found between athletes with and without preinjury migraines (22.0 ± 16.4 vs 20.5 ± 15.8, U = 48 719.0, P = 0.471). Athletes with preinjury migraines reported greater severity of "sensitivity to light" (1.59 ± 1.59 vs 1.23 ± 1.41, P = 0.040) and "feeling more emotional" (0.91 ± 1.27 vs 0.70 ± 1.30; P = 0.008) and were more likely to endorse "feeling more emotional" (45.2% vs 29.5%, P = 0.002). No differences were found across all other symptoms, including headaches (migraine = 87.1% vs no migraine = 86.3%, P = 0.835). In a multivariable model, a history of migraine was not a significant predictor of acute PCSS scores, but those with a history of psychological disorders (β = 0.12, P <0 .001) and greater number of days to symptom evaluation (β = 0.08, P = 0.005) had higher PCSS scores.

CONCLUSIONS

Collegiate athletes with a pre-existing history of migraines did not have higher acute symptom burden after SRC.

Validity and reliability of Arabic version of pediatric migraine disability assessment scale (Child Self-Report versus Parent Proxy-Report): a multi-center study

BACKGROUND

Pediatric Migraine Disability Assessment (PedMIDAS) is one of the most frequently used questionnaires to assess disability from migraine in pediatric patients. This work aimed to evaluate the validity and test-retest reliability of the Arabic version of the child self-report versus the parent proxy report PedMIDAS. We also aimed to test the agreement between children's and parents' reports of the scale.

METHODS

PedMIDAS was subjected to translation and back-translation, then applied to 112 pediatric patients fulfilling the migraine diagnostic criteria. This cross-sectional study was conducted on two visits, one week apart. At visit 1, the following data were obtained from the included pediatric patients: disease duration, migraine type, current treatment regimen, monthly migraine days (MMD) during the last month preceding the enrollment, and migraine intensity using the visual analogue scale. Then, each child and his parent were independently asked to fill out PedMIDAS and Child Self-Report of the Pediatric Quality of Life Inventory™ 4.0 (PedsQL™) to test the convergent validity of PedMIDAS. At visit 2, each child was requested to complete PedMIDAS again, and so was the parent to evaluate test-retest reliability.

RESULTS

Cronbach's alpha was estimated to be 0.94 for each instrument. For the child-self report PedMIDAS, the average measure intraclass correlation coefficient (ICC) value was 0.992 (95%CI = 0.989-0.995), while it was estimated to be 0.990 for the parent-proxy report with 95%CI = 0.985-0.993, indicating excellent test-retest reliability for both instruments. The child-self report and the parent-proxy report PedMIDAS scores were significantly correlated with MMD, VAS, and all domains of the corresponding PedsQL, supporting convergent validity for both instruments. Agreement between parent and child on disability grading categories of PedMIDAS was substantial (κ = 0.644).

CONCLUSION

The Arabic version of PedMIDAS was a valid and reliable instrument to assess disability from migraine in Arabic-speaking pediatric patients with migraine. Parent reports can be valuable as a complement to child reports for a comprehensive assessment of migraine.

Clinical Correlates of Osmophobia in Primary Headaches: An Observational Study in Child Cohorts

Primary headaches, especially migraines, have a significant impact on physical and mental health, as well as on the scholarly performance and quality of life of children and adolescents. Osmophobia could be a potential diagnostic marker of migraine diagnosis and disability. This multicenter observational cross-sectional study included 645 children, aged 8-15, with a diagnosis of primary headaches. We took into consideration the duration, intensity and frequency of headaches, pericranial tenderness, allodynia and osmophobia. In a subgroup of migraine children, we evaluated the migraine-related disability, Psychiatric Self-Administration Scales for Youths and Adolescents, and the Child Version of the Pain Catastrophizing Scale. Osmophobia was found to be present in 28.8% of individuals with primary headaches, with children suffering from migraines having the highest prevalence (35%). Migraine patients with osmophobia also showed a more severe clinical picture, with enhanced disability, anxiety, depression, pain catastrophizing, and allodynia symptoms (F Roy square 10.47 p < 0.001). The presence of osmophobia could help in identifying a clinical migraine phenotype coherent with an abnormal bio-behavioral allostatic model that is worthy of prospective observations and careful therapeutic management.

Investigation of the plasma copeptin level in cases with childhood migraine

Copeptin is a hypothalamic stress hormone that is synthesized in the hypothalamus together with Arginine-vasopressin and circulated from the neurohypophysis in equimolar amounts and can indicate the individual stress level. The aim of this study was to investigate the plasma copeptin level for childhood migraine headache. In this study, total oxidant status (TOS); total antioxidant status (TAS); oxidative stress index (OSI); and copeptin were measured in the plasma samples of 61 migraine patients and 60 matched healthy participants. The median plasma copeptin levels in the patients group and control group were 298.25 and 194.35 pg/mL, respectively. Copeptin levels were significantly higher in migraine patients than in the healthy control group. The specificity and sensitivity of copeptin for 249.5 pg/dL cut off value predicting diagnosis of migraine were 67% and 64%, respectively. In addition, TOS and OSI levels were found to be higher and TAS levels were significantly lower in patients with migraine than healthy controls. Plasma copeptin levels are thought to increase in cases of childhood migraine secondary to increased oxidative stress. In the diagnosis of childhood migraine cases, it can be used together with oxidative stress biomarkers such as TAS, TOS and OSI as a complementary parameter.

Validation of the Spanish version of the migraine disability assessment questionnaire (MIDAS) in university students with migraine

BACKGROUND

The Migraine Disability Assessment (MIDAS) questionnaire is widely used to determine the degree of migraine-related disability of subjects. So far, and to the best of our knowledge, no Spanish version of this tool has been validated. The questionnaire comprises seven items, with the first five constituting the main scale while the sixth and seventh items referring, respectively, to the frequency and intensity of headache. The present study aims to analyze the clinimetric properties of the Spanish version of the MIDAS questionnaire in a population of university students.

METHODS

We performed a cross-sectional study of validation for this measuring instrument. A total of 153 subjects participated in the study. We analyzed construct validity using factor analysis, test-retest reliability by the Intraclass Correlation Coeficient (ICC), internal consistency, and concurrent validity with respect to the 12-Item Short Form Health Survey (SF-12).

RESULTS

Factor analysis revealed a two-factor structure. The questionnaire has good reliability for the MIDAS main-scale score ([ICC = 0.81; 95% CI: 0.63-0.90]), excellent reliability for headache frequency (ICC = 0.90; 95%; CI: [0.79-0.95]), and moderately good reliability for headache intensity (ICC = 0.63; 95% CI: [0.34-0.80]). The analysis also yielded good internal consistency results (α Cronbach = 0.797) and a moderate correlation between MIDAS-main scale and the physical component summary of SF-12 (Rho = - 0.326; p <  0.001).

CONCLUSIONS

The Spanish version of the MIDAS questionnaire is a valid and reliable tool to measure migraine-related disability in university subjects. The two additional items provide information that could help clinicians in making decisions.

Pain Catastrophizing in Childhood Migraine: An Observational Study in a Tertiary Headache Center

Background: Migraine is the most common cause of primary headache in children leading to a decrease in the quality of life. During the last decade, pain catastrophizing construct became a major focus of interest in the study and treatment of pain.

Aim of the study:

To evaluate pain catastrophizing in episodic and chronic migraine children and adolescents selected in a tertiary headache Center.

To test whether the children's pain catastrophizing might be associated (a) with the frequency of attacks and disability (b) with psychopathological aspects (c) with allodynia and total tenderness score as symptom of central sensitization.

To test the best discriminating clinical variables and scores between episodic and chronic migraine, including pain catastrophizing.

Methods: We conducted a cross sectional observational study on consecutive pediatric patients affected by migraine. We selected 190 headache patients who met the diagnostic criteria for Migraine without aura, Migraine with aura and Chronic migraine. We submitted all children to the Child version of the Pain Catastrophizing Scale (PCS-C), and to the disability scale for migraine (PedMIDAS), general quality of life estimated by children (PedsQL) and parents (PedsQL-P), anxiety and depression (SAFA-A; SAFA-D) scales. We also evaluated headache frequency and the presence and severity of allodynia and pericranial tenderness.

Results: No difference was detected in Total Pain Catastrophizing score (PCS-C) between chronic and episodic migraine groups (ANOVA F = 0.59, p = 0.70); the PedMIDAS, the PedsQL-P for physical functioning and the Total Tenderness Score were discriminant variables between episodic and chronic migraine. The PCS-C was not correlated with migraine related disability as expressed by Ped MIDAS, but it was significantly correlated with general low quality of life, allodynia, pericranial tenderness, anxiety, and depression.

Conclusion: Pain catastrophizing seems a mental characteristic of a clinical phenotype with psychopathological traits and enhanced expression of central sensitization symptoms. This clinical profile causes general decline in quality of life in the child judgment, with a probable parents' underestimation. In childhood age, it would not be a feature of chronic migraine, but the possibility that it could predict this evolution is consistent and worthy of further prospective evaluation.

Symptoms of central sensitization and comorbidity for juvenile fibromyalgia in childhood migraine: an observational study in a tertiary headache center

Background

Central sensitization is an important epiphenomenon of the adult migraine, clinically expressed by allodynia, pericranial tenderness and comorbidity for fibromyalgia in a relevant number of patients. This study aimed to evaluate the frequency and the clinical characteristics of allodynia, pericranial tenderness, and comorbidity for Juvenile Fibromialgia (JFM) in a cohort of migraine children selected in a tertiary headache center.

Methods

This was an observational cross-sectional study on 8–15 years old migraine patients. Allodynia was assessed by a questionnaire. Pericranial tenderness and comorbidity for JFM as well as their possible association with poor quality of life and migraine related disability, and with other clinical symptoms as anxiety, depression, sleep disorders and pain catastrophizing, were also evaluated.

Results

One hundred and fifty one patients were selected, including chronic migraine (n°47), migraine without aura (n° 92) and migraine with aura (n° 12) sufferers. Allodynia was reported in the 96,6% and pericranial tenderness was observed in the 68.8% of patients. Pericranial tenderness was more severe in patients with more frequent migraine and shorter sleep duration. Allodynia seemed associated with anxiety, pain catastrophizing and high disability scores. Comorbidity for JFM was present in the 0.03% ofpatients. These children presented with a severe depression and a significant reduction of quality of life as compared to the other patients.

Conclusions

This study outlined a relevant presence of symptoms of central sensitization among children with migraine. Severe allodynia and comorbidity for JFM seemed to cause a general decline of quality of life, which would suggest the opportunity of a routine assessment of these clinical features.

Laser-evoked potential habituation and central sensitization symptoms in childhood migraine

Objectives

Few studies have addressed central sensitization symptoms and pain processing in childhood migraine. Our aims were to examine pain sensitivity and responses, including habituation, evoked by CO2 laser stimuli (laser-evoked potentials (LEPs)) in a cohort of children with migraine compared to non-migraine controls and to determine the correlation between LEP features and signs of central sensitization.

Methods

Thirty-five patients 8–15 years of age with migraines without aura were evaluated during the inter-critical phase and were compared to 17 controls. LEPs were analyzed, and their main features were correlated with clinical symptoms including allodynia and pericranial tenderness.

Results

The laser-evoked pain threshold was lower and the N2P2 vertex complex amplitude was higher in children with migraines. Furthermore, habituation of vertex waves of LEPs clearly showed a tendency toward progressive amplitude enhancement in the migraine group. Acute allodynia and inter-critical pericranial tenderness correlated with trigeminal LEP features, particularly with the abnormal habituation pattern.

Discussion

Abnormalities of pain processing and symptoms of central sensitization appear to be characteristics of children with migraine. Reduced habituation and progressive amplification of cortical responses to laser stimuli indicate an overactive nociceptive system at the onset of migraine, and this hyperactivity may subtend allodynia and pericranial tenderness. Future prospective trials may aid in the early identification of clinical phenotypes that display a tendency to develop into the chronic form of migraine, warranting a timely therapeutic approach.

Migraine and tension type headache in adolescents at grammar school in Germany - burden of disease and health care utilization

Background

Tension-type headache and migraine are among the most prevalent chronic disorders in children/adolescents. Data on health care utilization for headache in this age group, however, are sparse.

Methods

In 1399 grammar school students (aged 12–19 years) with headache in the last six months in Germany a) the burden of disease for headache (mean intensity, mean frequency in the last three months and PedMIDAS means), b) medical care utilization defined by proportion of students consulting a physician in the last 12 months and/or taking analgetic drugs in the last three months by headache types (migraine and tension-type headache) and by burden of disease were assessed.

Results

Primary headache substantially impaired daily living activities in adolescents which was mainly related to migraine. Medical care utilization and drug use, however, was low (consulting a physician: 12.0 %, 95 %-CI = [10.3-13.8]; taking analgetic drugs: 29.9 %, 95 %-CI = [27.5-32.4]) - even among students with severe headache (physician consultation: <35 %; taking analgetic drugs: <63 %). Two thirds of students with any headache and 40 % of those with migraine had neither seen a physician nor used analgetic drugs because of their headache in the preceding 12 months.

Conclusions

Adolescents with headache might too rarely seek professional help for treatment of headache. Health promotion in adolescents should increase awareness for evidence-based treatment options for headache.

Quality of life in primary headache disorders: A review

BACKGROUND

Health-related quality of life (HRQoL) is emerging as an important element of clinical research in primary headache disorders, allowing a measure of the impact of headache on patients' well-being and daily life. A better understanding of this may contribute to improved resource allocations and treatment approaches.

OBJECTIVE

The objective of this study is to review available data on HRQoL in primary headache disorders and identify any influencing factors.

METHODS

Database searches including MEDLINE, PsycINFO and EMBASE were performed. Studies that investigated HRQoL in patients with primary headache disorders were included and reviewed. Trials that evaluated the efficacy of medications or interventions were excluded.

RESULTS

A total of 80 articles were included in the review. Both physical and emotional/mental aspects of HRQoL were impaired across headache subtypes, although the extent varied depending on headache type. A number of factors influencing HRQoL were also identified.

CONCLUSION

This narrative review suggests that headache, particularly in its chronic form, has a great impact on HRQoL. Clinical practice should not solely focus on pain alleviation but rather adopt routine assessment of HRQoL. Furthermore, identification and management of associated psychological comorbidities, which can significantly influence HRQoL in headache sufferers, are essential for optimal clinical management.

Migraine, tension-type headache, and attention-deficit/hyperactivity disorder in childhood: a population-based study

OBJECTIVES

Primary headache syndromes (eg, migraine and tension-type headache [TTH]) and attention-deficit/hyperactivity disorder (ADHD) are prevalent in childhood and may cause impairment in social and academic functioning. We tested if ADHD or its symptoms are associated with specific headache syndromes or with headache frequency.

STUDY DESIGN

Cross-sectional epidemiological study with direct interviews to parents and teachers using validated and standardized questionnaires.

SETTING

Populational study.

PARTICIPANTS

Children aged 5 to 11 years (n = 1856).

OUTCOME MEASURES

Prevalence of ADHD as a function of headache status in crude and adjusted analyses.

RESULTS

The prevalence of migraine was 3.76%. Infrequent episodic TTH occurred in 2.3% of the sample, and frequent episodic TTH occurred in 1.6%. The prevalence of ADHD was 6.1%. The prevalence of ADHD was not significantly different by headache category. For hyperactivity-impulsivity symptoms, the prevalence was 8.1% in children without headache, 23.7% in children with migraine (relative risk [RR], 2.6; 95% confidence interval [CI], 1.6-4.2), and 18.4% in children with probable migraine (RR, 2.1; 95% CI, 1.4-3.2). For inattention, no significant differences were seen. In multivariate analyses, ADHD or inattention symptoms were not predicted by headache subtypes or headache frequency. Hyperactivity-impulsivity symptoms were significantly associated with any headache (P < 0.01), TTH (P < 0.01), or migraine (P < 0.001).

CONCLUSION

Migraine and TTH are not comorbid to ADHD overall, but are comorbid to hyperactive-impulsive behavior. Providers and educators should be aware of the association.

Headache diagnosis, disability and co-morbidities in a multi-ethnic, heterogeneous paediatric Asian population

This was a questionnaire survey on headache and migraine prevalence in 2873 Singaporean schoolchildren aged 6 to 16 years. ICHD-II headache classification, disability assessment with PedMIDAS and screening of psychosocial co-morbidities with the Paediatric Symptom Checklist were conducted. Lifetime headache prevalence was high at 80.6%, migraine prevalence was 8.6% and tension headache prevalence was 10.0%. Headache and migraine prevalence was high compared with that found in other Asian studies. Factors significantly associated with headache included adolescent age (OR = 1.5 [95% CI 1.3–1.9], p < .001), female gender at primary (OR = 1.4 [95% CI 1.1–1.8], p = .003) and secondary (OR = 1.8 [95% CI 1.3–2.5], p < .001) levels and Malay ethnicity at the primary level (OR = 2.8 [95% CI 1.6–4.9], p < .001). The average PedMIDAS score for headache disability was 3.2 ± 8.4, and migraine disability (PedMIDAS 8.1 ± 11.2–15.2 ± 29.6) was lower than in some studies. Self-medication (20.5%) and use of alternative therapy (59.0%) were high among chronic daily headache sufferers. Routine sleep and stress screening is recommended for children with headaches. Recognition of the influence of genetics, lifestyle and cultural factors on headache management should be emphasized.

Measuring the Impact of Headache in Children: A Critical Review of the Literature

Headache is the most frequent neurological symptom and commonest manifestation of pain in childhood. Measuring the impact of headache in terms of health status, functioning and quality of life can inform the prioritization of competing resource claims, screen for unmet need, improve communication between patient and physician and monitor response to treatment. We undertook a critical review of the literature measuring the impact of headache in children and identified 33 papers that contained relevant information. Findings reflected a wide range of settings, age groups, methodologies and outcome measures. Considerable methodological limitations affected all studies, including inadequate description of study design, methodology and data analysis. Nevertheless, although we found the existing literature to be of inconsistent quality, the impact of headache in children and adolescents is substantial. Rigorous studies are required to quantify this burden using measures that are valid and reliable and whose development has been informed by both theoretical and practical perspectives.

Magnesium as a preventive treatment for paediatric episodic tension-type headache: results at 1-year follow-up

The objective was to confirm the long-term utility of magnesium salts treatment on a group of young patients suffering from episodic tension-type headache (ETTH). The study was carried out at the Outpatient Headache Center at the National Neurological Institute "C. Besta," Milan, Italy, with 45 children/adolescents with ETTH reporting consecutively for treatment. Magnesium pidolate (2.25 g) was given twice per day for three months. Medication was not administered during the year of follow-up. No other treatment was provided at any time. Patients showed significant symptom reduction. Headache days decreased by 69.9%, whereas analgesics consumption was reduced by 65.4%. Overall disability levels improved by the greatest percent - 75.7%. MIDAS subscores improved as well (question A=58.0%; question B=22.5%). Although uncontrolled, these findings are encouraging and suggest that further, better controlled research investigations are warranted.

Determinants of disability in everyday activities differ in primary and cervicogenic headaches and in low back pain

The aim of this study was to test whether the association between disability and depressive symptoms in patients with cervicogenic headache is similar to that found in primary headaches or to the pattern found in low back pain. During a 2-year period, 716 consecutive patients with the clinical diagnosis of cervicogenic headache (n=182), low back pain (n=116), migraine (n=231), tension-type headache (n=176), and cluster headache (n=11) filled in the Beck Depression Inventory (BDI). Disability was scored by the migraine disability score questionnaire reflecting the number of days with lost or decreased work, household and social activities. Non-parametric tests and multiple general regression were used for statistical analysis. In multivariate testing, significant independent determinants of disability were pain frequency, pain intensity and the severity of depressive symptoms in migraine and tension-type headache; pain frequency and the BDI score in cervicogenic headache, and pain frequency alone in low back pain. Disability is related to pain frequency in all pain syndromes evaluated in the present study. The level of disability is associated with the severity of pain only in primary headaches, but not in pain syndromes of vertebral origin (cervicogenic headache and low back pain). Disability is associated with the severity of depressive symptoms in all headache types but not in low back pain. Both the location and the etiology of pain have importance in determining the interrelationship between pain characteristics, depression and disability.

Behavioral assessment and treatment of pediatric headache

Headaches are quite common in children and adolescents, and they appear to persist into adulthood in a sizable number of individuals. Assessment approaches (interview, pain diaries, and general and specific questionnaires) and behavioral treatment interventions (contingency management, relaxation, biofeedback, and cognitive behavior therapy) are reviewed, as is the evidence base for their use. The article concludes with practical suggestions for headache management.

Methodological considerations in research with special populations: children and adolescents

Headache occurs across the lifespan, but limited attention has been devoted to children and adolescents. This article discusses pertinent methodological considerations when conducting behavioral research with pediatric populations. Issues needing special consideration when working with children and adolescents involve ethics, sample characterization, headache diagnosis, treatment administration, and outcome measurement. Available literature is reviewed and specific recommendations are offered when possible.

Disability is the major determinant of the severity of depressive symptoms in primary headaches but not in low back pain

Pain syndromes are often associated with depression. In a prospective study we analysed if determinants of depression differ among patients with different primary headaches and between headaches and non-headache pain. During a 2-year period between 1 February 2002 and 31 January 2004, 635 subjects (migraine n = 231; tension-type headache n = 176; cluster headache n = 11; patients with low back pain n = 103; and healthy subjects n = 114) seen by two neurologists filled in a questionnaire on pain characteristics, the MIDAS questionnaire and the Beck Depression Inventory. A multivariate general regression model was used to identify independent predictors of the severity of depressive symptoms. Pain was most frequent in chronic tension-type headache and most intense in the cluster subgroup (P < 0.001, Kruskal-Wallis ANOVA). In univariate tests gender, age, pain frequency, pain intensity and disability were all significantly associated with the severity of depressive symptoms. In the multivariate model disability was the most important independent determinant of the severity of depressive symptoms in the pooled headache group as well as in the migraine and tension-type headache subgroups. In contrast to patients with headache, pain frequency and pain intensity were the significant independent predictors of the severity of depressive symptoms in patients with low back pain. In a multivariate model, after controlling for other factors, determinants of the severity of depressive symptoms were different in headache and non-headache pain subjects, suggesting a different mechanism for developing depression in primary headaches and in other pain syndromes.

Primary headaches in an outpatient neurology headache clinic in East Hungary

The majority of patients with primary headache do not seek medical help. In the present study we analyse the characteristics of those patients with primary headaches who consulted a single headache outpatient service in East Hungary. All consecutive patients with primary headaches referred to the headache center between February 2002 and April 2003 were asked to fill in a questionnaire on headache characteristics and the migraine disability score (MIDAS) form. A total of 327 patients had some form of primary headache: 42% migraine, 31% tension-type headache, 1% cluster headache and 26% had combination headache. Of the patients 95% were younger than 60 years of age. Only 16% of the patients were male. Chronic daily headache was found in 41% of patients. Although headache was the least severe in tension-type headache, reported disability occurred on much more days in this group than in migraine patients. The majority of patients with primary headache were in the active age group. Patients with tension-type headache need more attention, as disability is more severe in this patient group than generally assumed. More attention to the headaches of men and the elderly could improve the quality of life in these groups of the Hungarian population.
