Reliability and validity of the migraine disability assessment scale among migraine and tension type headache in Iranian patients

The association between dietary antioxidant quality score and intensity and frequency of migraine headaches among women: a cross-sectional study

BACKGROUND

Migraine is an episodic disorder and a frequent form of headache. An impaired balance between free radical production and an impaired antioxidant defense system leading to oxidative damage may play a major role in migraine etiology. We sought to investigate whether dietary antioxidant quality score (DAQS) is associated with migraine intensity and frequency among women suffering from migraine.

METHODS

This cross-sectional study was conducted on 265 women. The data related to anthropometric measures and dietary intake were collected. DAQS score was calculated based on FFQ (food frequency questionnaire) vs. the reference daily intake (RDI) quantity. To measure migraine intensity, the migraine disability assessment questionnaire (MIDAS) and visual analog scale (VAS) were used. The frequency of headaches was defined as the days the participants had headaches in the last month and a 30-day headache diary was used.

RESULTS

The results of the study demonstrated that VAS, MIDAS, and frequency of headaches were reduced significantly from the low DAQS (poor quality of antioxidants) to high DAQS (high quality of antioxidants) after adjusting covariates. Also, multinomial regression showed there was an inverse association between higher DAQS and the frequency of headaches. In the adjusted model, subjects with the higher DAQS were 69% less likely to have moderate migraine disability, compared with those with the lower DAQS. Linear regression showed, there was an inverse association between vitamin C intake and the grades of pain severity.َAlso in a crude model, a negative association was found between vitamin E and the frequency of headaches.

CONCLUSION

In conclusion, Participants with higher DAQS had lower migraine intensity and headache frequency. In addition, the consumption of vitamin C may potentially associate with decreasing the severity of headaches. Dietary antioxidants should be monitored closely in individuals suffering from migraine.

Relationship of myofascial trigger points with related disability, anxiety, and depression in patients with migraine headaches

BACKGROUND

Migraine affects one in ten individuals worldwide and is the second leading cause of disability. Studies have shown an association between migraine and the musculoskeletal system, and myofascial trigger points (MTrPs) play an essential role. Additionally, those with myofascial pain have been proven to experience higher levels of depression and anxiety. Understanding the association between MTrPs and migraine is crucial for developing targeted treatment strategies. Additionally, recognizing the link between MTrPs and migraine-related depression and anxiety underscores the importance of a holistic approach to migraine management. By addressing both musculoskeletal and neurological factors, healthcare providers can provide more effective and personalized care for migraine patients. This study aims to determine the association between MTrPs with migraine-related disability, anxiety, depression, and migraine characteristics.

METHODS

This cross-sectional study included 68 migraine patients from an outpatient neurology clinic. The number of MTrPs was determined through examination by an experienced neurologist during a migraine-free period using the recommended international criteria. We evaluated anxiety and depression with the Hospital Anxiety and Depression Scale (HADS) and disability with the Migraine Disability Assessment Scale (MIDAS).

RESULTS

We enrolled 68 patients (22 males) with a mean age of 36.23 ± 9.63 years. The mean number of MTrPs was 2.75 ± 2.934. MTrPs were positively correlated with severity (CC: 0.576, P-value < 0.001). There was no association between MTrPs and HADS-D or MIDAS, but migraine patients with abnormal HADS-A scores had more MTrPs than patients with normal HADS-A scores (0.6 ± 0.84 vs 3.56 ± 3.11, P-value:0.013).

CONCLUSIONS

The number of MTrPs is associated with higher anxiety levels and headache intensity. Further research could investigate the impact of MTrP-based therapies on anxiety among individuals suffering from migraines.

Transcranial direct current stimulation for chronic headaches, a randomized, controlled trial

Background and objectives

Chronic headaches are a frequent cause of pain and disability. The purpose of this randomized trial was to examine whether transcranial direct current stimulation (tDCS) applied to the primary motor cortex, reduces pain and increases daily function in individuals suffering from primary chronic headache.

Materials and methods

A prospective, randomized, controlled trial, where participants and assessors were blinded, investigated the effect of active tDCS vs. sham tDCS in chronic headache sufferers. Forty subjects between 18 and 70 years of age, with a diagnosis of primary chronic headache were randomized to either active tDCS or sham tDCS treatment groups. All patients received eight treatments over four consecutive weeks. Anodal stimulation (2 mA) directed at the primary motor cortex (M1), was applied for 30 min in the active tDCS group. Participants in the sham tDCS group received 30 s of M1 stimulation at the start and end of the 30-minute procedure; for the remaining 29 min, they did not receive any stimulation. Outcome measures based on data collected at baseline, after eight treatments and three months later included changes in daily function, pain levels, and medication.

Results

Significant improvements in both daily function and pain levels were observed in participants treated with active tDCS, compared to sham tDCS. Effects lasted up to 12 weeks post-treatment. Medication use remained unchanged in both groups throughout the trial with no serious adverse effects reported.

Conclusion

These results suggest that tDCS has the potential to improve daily function and reduce pain in patients suffering from chronic headaches. Larger randomized, controlled trials are needed to confirm these findings.

Trial registration

The study was approved by the local ethics committee (2018/2514) and by the Norwegian Centre for Research Data (54483).

Effects of cinnamon on anthropometric indices and headache-related disability of patients with migraine: A randomized double-blind placebo-controlled trial

Objective

Increased body mass index (BMI) seems to be a risk factor for migraine attacks. Cinnamon has anti-inflammatory, neuroprotective, and anti-obesity effects. This study aimed to assess the effects of cinnamon on anthropometric indices and headache-related disability of patients with migraine.

Materials and Methods

This study was conducted as a randomized, double-blind, placebo-controlled trial involving 50 migraine patients. Patients were randomized to receive either 600 mg cinnamon powder or placebo capsules for two months. Height, body weight (BW), waist circumference (WC), and hip circumference (HC) were measured.Furthermore, Minimal or Infrequent Disability (MIDAS) and Headache Daily Result (HDR) Questionnaires were recorded.

Results

At the end of the treatment period, BW and BMI did not change in the intervention group; however, both factors were significantly increased in the placebo group (p=0.001). The change of WC, HDR and MIDAS was significantly different between the intervention and placebo groups (p<0.001). Furthermore, HC and WHR significantly decreased (p=0.001).

Conclusion

Cinnamon seems to have beneficial effects on anthropometric indices and headache disability of migraine patients.

The efficacy of transdiagnostic cognitive behavioral therapy on migraine headache: a pilot, feasibility study

Introduction

Psychological interventions are shown to be effective in migraine, but not utilized routinely yet. We aimed to evaluate the efficacy of transdiagnostic cognitive behavioral therapy (TCBT) on people with migraine (PwM).

Method

This study was conducted on 40 PwM aged 20–50 years. We randomly assigned participants to two groups of intervention, receiving 10 sessions of TCBT, and control, attending one session on relaxation and stress-management techniques. Days with headache, headache severity, migraine-related disability and effects on daily life, number of pain-relivers taken for headache, depression, and anxiety were assessed pre-intervention, post-intervention (three-month follow-up), and one-month after TCBT termination (four-month follow-up).

Results

Thirty-five participants suffering moderate to severe migraine completed the study (16 and 19 in TCBT and control groups, respectively). TCBT improved all measured items between study time-points (p < 0.05) in the intervention group, while such an improvement was not observed in the control group. Between group comparisons revealed superiority of TCBT group compared to the control group in most measured items at three- and four-month follow-ups (p < 0.05).

Conclusion

Ten sessions of TCBT improved migraine severity, associated disability, anxiety, and depression in PwM, with persistent effects after one month of therapy termination. However, the generalizability of these findings is limited due to the placebo effect in the intervention arm, given the more time each participant has spent with the therapist. TCBT could be an affordable, practical, and feasible intervention to be utilized for PwM and larger studies with equal number of sham therapy sessions are needed to further explore this.

Trial registration number: The study protocol was registered in clinicaltrial.gov (NCT03701477) prior to enrollment.

B vitamins and their combination could reduce migraine headaches: A randomized double-blind controlled trial

Background: The B vitamins can potentially help prevent migraine. This study was designed to examine the effects of supplementation with thiamine (B1), pyridoxine (B6), cobalamin (B12), folic acid (B9), and a combination of these vitamins on women with episodic migraine (EM). Methods: This study was a double-blind, placebo-controlled, randomized, clinical trial conducted on 120 women with EM. The participants were divided into the 6 groups of B1 (n = 20), B6 (n = 20), B12 (n = 20), B9 (n = 20), vitamin B complex (n = 20), and placebo (n = 20). Subjects received 1 capsule daily for 12 weeks. As part of the baseline and post-intervention phases, paper-based headache diaries were used to record the number of abortive drugs consumed and the frequency of headache attacks, and the Migraine Disability Assessment Questionnaire (MIDAS) was used to assess migraine disability. Results: A 16-week study on women with EM revealed that the mean changes in the frequency of headache attacks decreased significantly in all vitamin groups in comparison with the placebo group (P < 0.001). In contrast to the placebo, there was also a significant improvement in the migraine disability score in each vitamin group (P < 0.001). The 12-week supplementation with vitamins B9, B1, B6, B12, and B complex also brought on a significant decrease in the use of abortive drugs compared to the placebo group (P = 0.032). Conclusion: The results of this study showed that B1, B6, B12, and B9, and a combination of these vitamins could be effective as an adjuvant in treatment and prophylaxis of EM. Further large trials with long-term follow-ups will be required to confirm our results.

A comparative study on the effectiveness of topiramate and propranolol in patients with migraine with aura

Background: Migraine is considered as one of the most common and disabling diseases of the nervous system that has a great impact on quality of life (QOL) and a little risk of neurologic complications such as stroke. Migraine aura is known to be the result of cortical spreading depression and is associated with higher risk of this complication. Thus, the present study was conducted with the aim to compare the effects of topiramate as an antiepileptic, and propranolol in patients with migraine with aura. Methods: The present randomized clinical trial was conducted on patients with migraine with aura referred to the neurology clinic of Golestan Hospital, Ahvaz, Iran, in the period of 2019-2020. The patients were randomized into two groups and received either topiramate or propranolol. The Migraine Disability Assessment Scale (MIDAS) score was evaluated before and at the end of three months after initiating the treatment. Results: Reduction in the MIDAS score in patients taking topiramate (-16.94) was greater than that in the propranolol group (-14.5), but this difference was not statistically significant (P > 0.005). No significant relationship was found between gender and changes in the MIDAS score after the treatment of both groups (P > 0.050). However, the changes in the MIDAS score were greater in younger patients, and this relationship was statistically significant (P < 0.050). Conclusion: There was no significant difference in the efficacy of topiramate and propranolol in patients with migraine with aura. No significant relationship was found between gender and changes in the MIDAS score after the treatment in both groups, but the reduction in the MIDAS scores was significantly higher in younger patients of both groups.

Identifying Chinese Medicine Patterns of Tension-Type Headache and Understanding Its Subgroups

Tension-type headache (TTH) is common among adults. Individualized management strategies are limited due to lack of understanding of subtypes of TTH. Chinese medicine (CM) uses the pattern differentiation approach to subtype all health conditions. There is, however, a lack of evidence-based information on CM patterns of TTH. This study aimed to identity common CM patterns of TTH. TTH sufferers were invited for a survey, consisting of a validated Chinese Medicine Headache Questionnaire (CMHQ), Migraine Disability Assessment Test, and Perceived Stress Scale. The CMHQ consisted of information about headache, aggravating and relieving factors, and accompanying symptoms. Principal component analysis was used for factor extraction and TwoStep cluster analyses for identifying clusters. ANOVA was used to compare cluster groups with disability and stress. In total, 170 eligible participants took part in the survey. The commonest headache features were continuous pain (64%); fixed location (74%); aggravated by overwork (74%), stress (74%), or mental strain (70%); and relieved by sleeping (78%). The commonest nonpain symptoms were fatigue (71%) and neck stiffness (70%). Four clusters, differing in their key signs and symptoms, could be assigned to three different CM patterns including ascendant hyperactivity of liver yang (cluster 1), dual qi and blood deficiency (cluster 2), liver depression forming fire (cluster 3), and an unlabelled group (cluster 4). Additionally, over 75% participants in clusters 1 and 2 have episodic TTH, over one-third participants in cluster 3 have chronic TTH, and a majority of participants in cluster 4 have infrequent TTH. The three patterns identified also differed in levels of disability and some elements of coping as measured with PSS. The three CM patterns identified are common clinical presentations of TTH. The new information will contribute to further understanding of the subtypes of TTH and guide the development of targeted intervention combinations for clinical practice and research.

Validity and reliability of the Portuguese version of the modified Migraine Disability Assessment

BACKGROUND

Migraine Disability Assessment Scale (MIDAS) is a useful tool to measure headache-related disability. Modified MIDAS with 4-week recall period reduces recall bias and improves accuracy of the results. This study aimed at validating mMIDAS in Portuguese.

METHODS

Studied population consisted of adult migraine patients attending a headache outpatient clinic. Reliability was assessed by internal consistency and reproducibility in a 3-week test-retest. Content validity was evaluated by two expert panels. Construct validity was tested by comparing mMIDAS-P index in socioeconomic and clinical patient groups and scale unidimensionality was evidenced by factor analysis. Criterion validity was tested using EQ-5D-5L and HADS.

RESULTS

Ninety-two patients, 88% female, mean age of 44 years, participated. They had, in average, 9.7 headache days in previous month, pain averaging 7.5/10. About 69.9% were on a migraine prophylactic treatment, and 42.4% had severe disability; 29.4 and 13.0% showed, respectively, moderate/severe anxiety and depression. Content validity showed that mMIDAS-P is simple and clinically useful. It did not show to be determined by patient's sociodemographic characteristics and it was correlated with depression scale and EQ-5D-5L. Test-retest demonstrated high reproductive reliability and good internal consistency.

CONCLUSION

mMIDAS-P is valid and reliable. We strongly recommend it for clinical and research use.

Longitudinal Modeling of Non-Pharmacological Factors Related to Frequency, Severity and Duration in Both Migraine and Tension-Type Headaches

BACKGROUND

Frequency, severity, and duration of attacks are some major parameters in headache management, affected by some other factors. Ignoring these factors in headache-related studies can lead to incorrect results. We aimed to model both socio-demographic characteristics and headache-associated symptoms related to frequency, severity and duration of headache attacks.

STUDY DESIGN

A longitudinal panel study.

METHODS

Overall, 275 migraines or tension Type Headache (TTH) patients were visited at three different times in 2012 in Isfahan, Iran. On the first visit socio-demographic characteristics and headache symptoms of the patients were asked. In all of the visits, headache frequency, severity and attack duration were recorded.

RESULTS

Frequency of headaches was influenced by headache type, age, job status, working hours, residency, disease duration, laterality, and type of pain onset. In terms of intensity, headaches were more severe in patients with migraine-type; those suffering from longer headache history; and those who suffered from vomiting, photophobia, and phonophobia. On the other hand patients with migraine, married people, women and patients suffering from vomiting experienced longer headache attacks.

CONCLUSION

Headache type (migraine/TTH), age, job status, residency, years of headache, laterality, type of onset, nausea, vomiting, photophobia, and phonophobia were the factors to be considered in the studies that would apply frequency, severity, and duration of headache attacks in order to evaluate headache management.

Estimating quality of life in a headache referral population based on Migraine disability assessment scale and headache impact test

Background: Headache is among the most common disabling neurologic disorders. We measured quality of life in chronic migraine (CM) and episodic migraine (EM), stratified by medication overuse headache (MOH) and presence of aura. Methods: In this observational study, conducted from January 2016 to December 2018, adult patients referred to the tertiary headache clinic of Sina Hospital in Tehran, Iran, who met International Classification of Headache Disorders, 3rd Edition-beta (ICHD-3 β) criteria for migraine were classified to EM and CM subtyped based on presence of aura and MOH. Validated Farsi versions of Migraine Disability Assessment Scale (MIDAS) and 6-item Headache Impact Test (HIT-6) questionnaires were used. Results: A total of 2454 patients (1907 women) were enrolled from which 1261 (51.4%) patients had EM and 1193 (48.6%) had CM, while 908 subjects (37.0%) had MOH, of whom 890 (98.0%) had CM. Median scores of MIDAS and HIT-6 were significantly higher in patients with CM compared to EM sufferers. Chronic migraineurs with MOH had a significantly higher median score of MIDAS and HIT-6 compared to patients with non-MOH CM. Also, there was a moderate positive correlation between MIDAS (disability) and HIT-6 scores (impact on patients' life) and a moderate correlation between HIT-6 and pain severity. Conclusion: The results of this study confirm that CM and MOH are associated with a higher headache-related disability and impact on life compared to EM. Therefore, treatment goals in prevention of MOH and migraine transformation warrant higher quality of life in patients with migraine.

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.

The effects of vitamin D supplementation on interictal serum levels of calcitonin gene-related peptide (CGRP) in episodic migraine patients: post hoc analysis of a randomized double-blind placebo-controlled trial

Background

Emerging evidence showed promising effects of vitamin D on headaches characteristics. Thus, it seems there is still a need for more researches to clarify the mechanisms by which this vitamin exerts anti-migraine effects.

Methods

The present study was conducted as a 16-week randomized double-blind placebo-controlled trial on 80 episodic migraine patients allocated in 2 parallel groups each consisted of 40 patients who received vitamin D 2000 IU/d or placebo. At baseline and after the intervention completion, headache diaries and migraine disability assessment questionnaire (MIDAS) were used to assess migraine related variables in patients. Also, interictal serum concentration of calcitonin gene-related peptide (CGRP) (as the dominant mediator of migraine pain pathogenesis) was evaluated using ELISA method.

Results

The mean (SD) of age in the vitamin D and placebo groups was 37 (8) and 38 (12) years, respectively. ANCOVA test adjusted for baseline values, and confounders showed vitamin D supplementation resulted in a significant improvement in MIDAS score after 12 weeks in the intervention group (21.49 (16.22–26.77)) compared to placebo (31.16 (25.51–36.82) P value: 0.016). Moreover, after controlling for baseline levels, and other variables using ANCOVA, CGRP level was appeared to be significantly lower following vitamin D supplementation (153.26 (133.03–173.49) ng/L) than the patients in the placebo arm (188.35 (167.15–209.54) ng/L) (P value = 0.022).

Conclusion

According to the current findings, vitamin D supplementation in episodic migraineurs, particularly in those with migraine with aura, may potentially improve migraine headache characteristics and disability probably through attenuating CGRP levels. Therefore, these results could provide a new insight into anti-nociceptive effects of vitamin D; however, more studies are required to confirm our findings.

Trial registration

The trial is registered in the Iranian registry of clinical trials (IRCT) at 11 July 2018, with IRCT code: IRCT20151128025267N6.

Outcome measures for assessing the effectiveness of non-pharmacological interventions in frequent episodic or chronic migraine: a Delphi study

OBJECTIVES

The aim of this Delphi survey was to establish an international consensus on the most useful outcome measures for research on the effectiveness of non-pharmacological interventions for migraine. This is important, since guidelines for pharmacological trials recommend measuring the frequency of headaches with 50% reduction considered a clinically meaningful effect. It is unclear whether the same recommendations apply to complementary (or adjunct) non-pharmacological approaches, whether the same cut-off levels need to be considered for effectiveness when used as an adjunct or stand-alone intervention, and what is meaningful to patients.

SETTING

University-initiated international survey.

PARTICIPANTS

The expert panel was chosen based on publications on non-pharmacological interventions in migraine populations and from personal contacts. 35 eligible researchers were contacted, 12 agreed to participate and 10 completed all 3 rounds of the survey. To further explore how migraine patients viewed potential outcome measures, four migraine patients were interviewed and presented with the same measurement tools as the researchers.

PROCEDURES

The initial Delphi round was based on a systematic search of the literature for outcome measures used in non-pharmacological interventions for headache. Suggested outcome measures were rated by each expert, blinded towards the other members of the panel, for its usefulness on a 5-point Likert scale ranging from definitely not useful to extremely useful. Results were combined using median values and IQRs. Tools rated overall as definitely or probably not useful were excluded from subsequent rounds. Experts further suggested additional outcome measures that were presented to the panel in subsequent rounds. Additionally, experts were asked to rank the most useful tools and provide information on feasible cut-off levels for effectiveness for the three highest ranked tools.

RESULTS

Results suggest the use of the Migraine Disability Assessment (MIDAS), Headache Impact Test (HIT-6) and headache frequency as primary outcome measures. Patient experts suggested the inclusion of a measure of quality of life and evaluation of associated symptoms and fear of attacks.

CONCLUSIONS

Recommendations are for the use of the MIDAS, the HIT-6 and headache frequency, in combination with an outcome measure for quality of life. Associated symptoms and fear of attacks should also be considered as secondary outcomes, if relevant for the individual target population. The cut-off level for effectiveness should be lower for non-pharmacological interventions, especially when used as an adjunct to medication.

Comparison of Pain-Related and Psychological Variables between Acute and Chronic Migraine Patients, and Factors Affecting Headache Chronicity

Background:

Migraine headache is classified as acute or chronic. In recent years, efforts have been made to identify the factors that might predispose individuals to develop the chronic-type headache. The present study aimed to draw a comparison between patients with acute and chronic migraine in terms of demographic, pain-related, and psychological variables. In addition, we also investigated factors affecting headache chronicity in such patients.

Methods:

The present cross-sectional study was conducted during 2017-2018. The target sample consisted of 250 patients with acute or chronic migraine who referred to various clinics affiliated to Shiraz University of Medical Sciences (SUMS), Shiraz, Iran, recruited by convenience sampling. All the participants filled in the questionnaires related to demographic characteristics, pain intensity, disability, depression, emotional intelligence, and anger. The data were analyzed using SPSS software (version 22.0) with t test, Chi-square test, and logistic regression analysis. P<0.05 was considered statistically significant.

Results:

Patients suffering from chronic migraine experienced higher levels of disability, depression, anger, and had lower levels of emotional intelligence compared to those with acute migraine. Based on the logistic regression analysis, variables that had a significant effect on headache chronicity were female gender (OR=5.81), married status (OR=3.77), patients with lower level of education (OR=0.26), headache duration (OR=1.53), disability (OR=0.28), depression (OR=3.66), and anger (OR=5.04).

Conclusion:

Variables such as disability, depression, and lack of anger control were among the key factors associated with headache chronicity in migraine patients.

Effect of Migraine Headache on Productivity of Patients According to Migraine Disability Assessment Score: A Cross-Sectional Study

Introduction

Migraine, a primary headache disorder, is usually recurrent with moderate to severe intensity. Migraine is the third most common cause of disability under the age of 50. There are various scoring systems for assessing this disability, one of which is MIDAS; the Migraine Disability Assessment Score. The objective of our study was to determine the extent of disability among migraine patients, patterns of prophylaxis, and their healthcare-seeking behaviors.

Methods

This survey was done in 50 migraine patients at Jinnah postgraduate medical Centre from April to May 2018. The questionnaire inquired about the demographic information, management of migraine, and effect of this condition on their sleep, and the last part had assessment to know about their functional disability.

Results

The majority of the patients were females with a mean age of 31 ± 10 years. Acetaminophen was the most common medication used during a migraine attack, followed by nonsteroidal anti-inflammatory drugs. Only 54% of subjects admitted using prophylaxis, out of which 94% had stopped taking it after some time, with the most common reason being their side effects. β-blockers were the most common prophylaxis used. Only 32% had a regular follow-up visit with their doctors. Patients were graded according to the MIDAS score as: little or no disability, 22%; mild disability, 14%; moderate disability, 24%; and severe disability, 40%.

Conclusions

The majority of migraine patients were found to have severe disability, which affected their daily work and social activities. Despite an increase in disability rate due to migraine, people do not seek regular medical care for this type of headache in Pakistan.

The validation of the Hungarian version of the ID-migraine questionnaire

Background

Despite its high prevalence, migraine remains underdiagnosed and undertreated. ID-Migraine is a short, self-administrated questionnaire, originally developed in English by Lipton et al. and later validated in several languages. Our goal was to validate the Hungarian version of the ID-Migraine Questionnaire.

Methods

Patients visiting two headache specialty services were enrolled. Diagnoses were made by headache specialists according to the ICHD-3beta diagnostic criteria. There were 309 clinically diagnosed migraineurs among the 380 patients. Among the 309 migraineurs, 190 patients had only migraine, and 119 patients had other headache beside migraine, namely: 111 patients had tension type headache, 3 patients had cluster headache, 4 patients had medication overuse headache and one patient had headache associated with sexual activity also. Among the 380 patients, 257 had only a single type headache whereas 123 patients had multiple types of headache. Test-retest reliability of the ID-Migraine Questionnaire was studied in 40 patients.

Results

The validity features of the Hungarian version of the ID-Migraine questionnaire were the following: sensitivity 0.95 (95% CI, 0.92–0.97), specificity 0.42 (95% CI, 0.31–0.55), positive predictive value 0.88 (95% CI, 0.84–0.91), negative predictive value 0.65 (95% CI, 0.5–0.78), missclassification error 0.15 (95% CI, 0.12–0.19). The kappa coefficient of the questionnaire was 0.77.

Conclusion

The Hungarian version of the ID-Migraine Questionnaire had adequate sensitivity, positive predictive value and misclassification error, but a low specificity and somewhat low negative predictive value.

Translation, cross-cultural adaptation and reliability of the German version of the migraine disability assessment (MIDAS) questionnaire

Background

The Migraine Disability Assessment (MIDAS) is a brief questionnaire and measures headache-related disability. This study aimed to translate and cross-culturally adapt the original English version of the MIDAS to German and to test its reliability.

Methods

The standardized translation process followed international guidelines. The pre-final version was tested for clarity and comprehensibility by 34 headache sufferers. Test-retest reliability of the final version was quantified by 36 headache patients completing the MIDAS twice with an interval of 48 h. Reliability was determined by intraclass correlation coefficients and internal consistency by Cronbach’s α.

Results

All steps of the translation process were followed, documented and approved by the developer of the MIDAS. The expert committee discussed in detail the complex phrasing of the questions that refer to one to another, especially exclusion of headache-days from one item to the next. The German version contains more active verb sentences and prefers the perfect to the imperfect tense. The MIDAS scales intraclass correlation coefficients ranged from 0.884 to 0.994 and was 0.991 (95% CI: 0.982–0.995) for the MIDAS total score. Cronbach’s α for the MIDAS as a whole was 0.69 at test and 0.67 at retest.

Conclusions

The translation process was challenged by the comprehensibility of the questionnaire. The German version of the MIDAS is a highly reliable instrument for assessing headache related disability with moderate internal consistency. Provided validity testing of the German MIDAS is successful, it can be recommended for use in clinical practice as well as in research.

Reliability and Validity of the Greek Migraine Disability Assessment (MIDAS) Questionnaire

BACKGROUND

The Migraine Disability Assessment (MIDAS) Questionnaire is a reliable and valid instrument for migraine-related disability. Such a tool is needed to quantify migraine-related disability in the Greek population.

OBJECTIVE

This validation study aims to assess the test-retest reliability, internal consistency, item discriminant and convergent validity of the Greek translation of the MIDAS.

METHODS

Adults diagnosed with migraine completed the MIDAS Questionnaire on two occasions 3 weeks apart to assess reliability, and completed the RAND-36 to assess validity.

RESULTS

Participants (n = 152) had a median MIDAS score of 24 and mostly severe disability (58% were grade IV). The test-retest reliability analysis (N = 59) revealed excellent reliability for the total score. Internal consistency was α = 0.71 for initial and α = 0.82 for retest completion. For item discriminant validity, the correlations between each question and the total score were significant, with high correlations for questions 2-5 (range 0.67 ≤ r ≤ 0.79; p < 0.01). For convergent validity, there was significant negative correlation between the total score and all RAND-36 subscales except for 'emotional wellbeing'. The negative correlation indicates that patients with a lower degree of disability according to their MIDAS score tended to have better wellbeing. Psychometric properties are comparable with those of other published validation studies of the MIDAS and the original. Findings on question 1 show that missing work/school days may be closely related with increased affect issues.

CONCLUSION

The Greek version of the MIDAS Questionnaire has good reliability and validity. This study allowed for cross-cultural comparability of research findings.

Harm avoidance and depression, anxiety, insomnia, and migraine in fifth-year medical students in Taiwan

PURPOSE

During medical school training, increased stress, depression, and anxiety are common. Certain personality traits, particularly harm avoidance (HA), may increase the risk of psycho-pathological disorders, insomnia, and migraine among medical students. This study evaluated the role HA may play on levels of stress, depression, anxiety, and insomnia among Taiwanese medical students starting their fifth and final year of medical school.

PATIENTS AND METHODS

A series of self-report questionnaires were used to measure the severity of anxiety, depression, and insomnia, as well as somatic symptoms, particularly migraine headache, among 143 Taiwanese fifth-year medical students (94 males and 49 females). Most had normal or mild levels of anxiety, depression, insomnia, and migraine.

RESULTS

HA personality trait was significantly associated with depression (all P ≤ 0.001) after adjusting for other factors. HA was not significantly associated with anxiety, insomnia, or migraine headache days.

CONCLUSION

HA personality trait was significantly associated with depression among fifth-year medical students in Taiwan.

Changing Efficacy of Wet Cupping Therapy in Migraine with Lunar Phase: A Self-Controlled Interventional Study

BACKGROUND The aim of this study was to evaluate the effect of blood-letting with wet cupping therapy (WCT) in migraine treatment and to determine whether there was any difference according to the phase of the moon when the treatment was applied. MATERIAL AND METHODS This self-controlled study was conducted in Karabuk between 2014 and 2016. Patients who were diagnosed with migraine were enrolled in the study. Migraine disability assessment questionnaire (MIDAS), demographic characteristics, migraine attack frequency and duration, and family history was used to assess the severity of headache. WCT was applied in 3 sessions and the questionnaire was administered before and 3 months after the final WCT session. Wilcoxon signed-rank test was used in pre-and posttreatment measurements, and the Chi-square test was used to check independence in two-way categorical tables. RESULTS A total of 85 patients were included. The reduction in MIDAS scores and number of migraine attacks was significantly greater in the WCT applications made in the first half of the month compared to those in the second half of the month. Although the reduction in visual analog scale (VAS) scores was greater in the second half of the month, it was also significant in the applications made in the first half of the month. CONCLUSIONS WCT was found to be an effective treatment of migraine. The effect on MIDAS, VAS, and the number of attacks was significantly better when the application was made in the second half of the month compared to those made in the first half.

The effectiveness of Orem's self-care program on headache-related disability in migraine patients

Background: Providing a self-care program appropriate for patient needs in a supportive educative nursing system format could reduce migraine-induced disability. This study was designed to determine the effectiveness of Orem's self-care program on headache related disability in migraine patients. Methods: In this randomized clinical trial, episodic migraine patients with or without aura who signed the informed consent were randomly assigned to two groups (44 patients each). The data collection tools included a demographic questionnaire, the Migraine Disability Assessment (MIDAS) questionnaire, an Orem cognition form, and a self-care checklist. The programs were held as four 30 to 45 minutes training sessions for experimental group. The MIDAS were filled out before and three months after program in two groups. Data were analyzed with SPSS statistical software, version 16 and using chi-square, Mann-Whitney and Wilcoxon tests. Results: There was no statistically significant difference between the two groups in terms of demographic variables (P > 0.05). The mean total MIDAS score in the experimental group, before and after the intervention was 28.1 ± 17.5 and 6.03 ± 4.52, respectively (P = 0.001); and for the control group, it was 37.6 ± 16.4 and 55.6 ± 14.5, respectively (P < 0.001). Also, there was a statistically significant difference in disability indices between the two groups after the intervention (P < 0.001). Conclusion: Self-care program was suitable for needs assessment and provided basis for acquiring positive results in order to decrease disability and saved patient treatment costs.

Evaluation of pain regression in patients with temporomandibular dysfunction treated by intra-articular platelet-rich plasma injections: a preliminary report

OBJECTIVE

The objective of this study was to evaluate the regression of temporomandibular pain as a result of intra-articular injections of platelet-rich plasma (PRP) to patients with temporomandibular joint dysfunction previously subjected to prosthetic treatment.

MATERIALS AND METHODS

The baseline study material consisted of 10 patients, both males and females, aged 28 to 53 years, previously treated due to painful temporomandibular joint dysfunction using occlusal splints. All patients were carried out to a specialist functional assessment of the dysfunction using the Polish version of the RDC/TMD questionnaire axis I and II. Intra-articular injections were preceded by a preparation of PRP. The injection sites were determined by the method used during arthroscopic surgical procedures. Following aspiration, 0.5 mL of plasma was injected into each temporomandibular joint.

RESULTS

The comparison of the intensity of pain during all examinations suggests a beneficial effect of the procedure being performed as the mean VAS score was 6.5 at examination I, 2.8 at examination II, and 0.6 at examination III.

CONCLUSION

Application of the intra-articular injections of platelet-rich plasma into the temporomandibular joints has a positive impact on the reduction of the intensity of pain experienced by patients treated for temporomandibular joint dysfunction.

Differential diagnostics of pain in the course of trigeminal neuralgia and temporomandibular joint dysfunction

Chronic oral and facial pain syndromes are an indication for intervention of physicians of numerous medical specialties, while the complex nature of these complaints warrants interdisciplinary diagnostic and therapeutic approach. Oftentimes, lack of proper differentiation of pain associated with pathological changes of the surrounding tissues, neurogenic pain, vascular pain, or radiating pain from idiopathic facial pain leads to improper treatment. The objective of the paper is to provide detailed characterization of pain developing in the natural history of trigeminal neuralgia and temporomandibular joint dysfunction, with particular focus on similarities accounting for the difficulties in diagnosis and treatment as well as on differences between both types of pain. It might seem that trigeminal neuralgia can be easily differentiated from temporomandibular joint dysfunction due to the acute, piercing, and stabbing nature of neuralgic pain occurring at a single facial location to spread along the course of the nerve on one side, sometimes a dozen or so times a day, without forewarning periods. Both forms differ significantly in the character and intensity of pain. The exact analysis of the nature, intensity, and duration of pain may be crucial for the differential diagnostics of the disorders of our interest.
