Headache, anxiety and depressive disorders: the HADAS study

The Environment and Headache: a Narrative Review

PURPOSE OF REVIEW

In this narrative review, we summarize the peer-reviewed literature published between 2017 and 2022 that evaluated ambient environmental risk factors for primary headache disorders, which affect more than half of the population globally. Primary headache disorders include migraine, tension-type headache (TTH), and trigeminal and autonomic cephalalgias (TAC).

RECENT FINDINGS

We identified 17 articles that met the inclusion criteria via PubMed or Google Scholar. Seven studies (41%) relied on data from US populations. The remaining studies were conducted in China, Taiwan, Germany, Ghana, Japan, the Netherlands, South Korea, and Turkey. Air pollution was the most frequently assessed environmental risk factor. Most studies were cross-sectional and focused on all-cause or migraine headaches; one study included TTH, and none included TAC. Short-term exposure to fine particulate matter (PM2.5) was not consistently associated with headache endpoints, but long-term exposure to PM2.5 was associated with migraine headache prevalence and severity across multiple studies. Elevated ambient temperature, changes in weather, oil and gas well exposure, and less natural greenspace, but not noise pollution, were also associated with headache. No studies considered water pollution, metal exposure, ultrafine particulate matter, or wildfire smoke exposure. There is a need for ongoing research focused on headache and the environment. Study designs with the greatest explanatory power may include longitudinal studies that capture the episodic nature of headache and case-crossover analysis, which control for time-invariant individual-level confounders by design. There is also a clear need for research that considers comorbid psychiatric illness and socioeconomic position as powerful modifiers of the effect of the environment on headache.

Assessing the efficacy and safety of Craniosacral therapy for migraine: A single center randomized controlled trial

OBJECTIVE

Design a feasible study to assess the efficacy and safety of Craniosacral therapy (CST) in the treatment of migraine, using a rigorous and innovative randomized controlled study design involving complementary light-touch sham treatments (CLST) as an attention control intervention.

METHODS

This was a single-center, randomized, cross-over placebo-controlled experimental design. A total of 87 participants who suffered migraine attacks from 4 to 9 per month were randomly assigned into either 2 weekly units of CST or CLST for 4 weeks. And then the 2 groups were crossed and continued treatment for 4 weeks plus a follow-up observation for 4 weeks. As the primary outcome measures, Headache Impact Test-6 (HIT-6) and headache frequency were assessed every 4 weeks (at baseline, week 4, week 8 and week 12). The secondary outcome was the scores of Headache Disability inventory (HDI) and the Hamilton Anxiety Scale (HAMA) as well as the adverse events.

RESULTS

All 87 individuals had been screened for eligibility, of which 60 were licensed for the study. The difference of HIT-6 and headache frequency between the 2 groups was not significant at the baseline. But the headache frequency and HIT-6 of 2 groups were all declined respectively after the CST at week 4 (group A) and week 8 (group B) than before (P☆= 0.01 < 0.05, 95% CI, -3.06 to -1.87; P※= 0.01 < 0.05, 95% CI, -3.52 to -2.53; P1A = 0.01 < 0.05, 95% CI, 4.55-11.7; P2B = 0.01 < 0.05, 95% CI, -11.78 to -6.01) while the changes were not obvious after CLST with previous treatment. The scores and frequency of fourth evaluation showed that there was no significant increase or decrease in both the 2 groups. Besides, we found that the mean scores of HIT-6 for all participants, compared with the baseline, were decreased significantly after the 3 round treatments (P3A = 0.01 < 0.05, 95% CI, -13.12 to -6.4; P3B = 0.01 < 0.05, CI, -12.73 to -6.69). We also showed the similar result in the scores of HDI and HAMA.

CONCLUSION

The results indicated that standardized CST was both effective and safe in alleviating the migraine intensity and frequency as well as the headache-related disability. Further larger research is needed.

Efficacy of Onabotulinum Toxin A on Obsessive–Compulsive Traits in a Population of Chronic Migraine Patients

Background: Drug addiction may play an important role in chronic migraine (CM) with medication-overuse headache (MOH). Psychiatric diseases are associated with CM, but data regarding obsessive–compulsive disorder (OCD) are lacking. We aimed to establish the prevalence of OCD traits in CM patients with MOH and the impact on onabotulinum toxin A (OBT-A) treatment. Methods: A total of 75 patients with CM and MOH undergoing treatment with OBT-A in our Headache Centre were evaluated. At baseline and after four injection sessions, we assessed the migraine burden and the presence of OCD traits with the Obsessive–Compulsive Inventory—Revised (OCI-R) test. Results: At baseline, 28% of patients had OCI-R scores compatible with borderline OCD aspects, while 22.7% were pathological. An improvement in headache was significantly associated with an increase in the number of subjects with a normal OCI-R score at T0 and T1, whereas patients with a pathological OCI-R score at T0 showed a significantly higher prevalence of CM at T1. Conclusions: Our data showed a significant rate of OCD traits at baseline, which could strengthen the hypothesis of an addictive disorder underlying CM with MOH. OCD traits seem to influence the OBT-A response. An OCD assessment could be useful in improving patients’ selections before starting treatments.

Psychiatric Comorbidity and Emotional Dysregulation in Chronic Tension-Type Headache: A Case-Control Study

Background: Chronic tension-type headache (CTTH) is frequently associated with a psychiatric comorbidity of depression and anxiety. Most studies focus their attention on this association, and only few link CTTH with psycho-affective emotional regulation disorders. Objective: To evaluate the association of CTTH with anxiety, depression, positive and negative affectivity, and emotional management in CTTH patients with neither a previous diagnosis of psychiatric disorder nor use of psychoactive drugs or abuse of analgesics. Design: Case-control study. Methods: Validated scores for state and trait anxiety, depression, positive and negative state and trait affect, cognitive reappraisal, and expressive suppression were assessed in 40 subjects with CTTH and 40 healthy subjects. Associations between CTTH and psychological status were assessed through linear multivariate regression models. Results: CTTH was associated with higher scores for depression (Beta = 5.46, 95% CI: 1.04–9.88), state and trait anxiety (Beta = 12.77, 95% CI: 4.99–20.56 and Beta = 8.79, 95% CI: 2.29–15.30, respectively), and negative state affect (Beta = 5.26, 95% CI: 0.88–9.64). Conclusions: CTTH is directly associated with depression, anxiety, and negative affectivity signs despite the absence of a previously diagnosed psychiatric disorder or psychopharmacological intake. The recognition of these comorbid and psycho-affective disorders is essential to adapt the emotional management of these patients for better control.

Morbidity and mortality in obsessive-compulsive disorder: A narrative review

Current knowledge on the general somatic health of individuals with obsessive-compulsive disorder (OCD) is very limited. Here, we critically review the emerging literature on the topic. Rapidly accumulating evidence indicates an association between OCD and autoimmune diseases, which is not limited to streptococcus-related conditions. Similarly, an association with metabolic and circulatory system diseases has been reported, which is at least partially independent from psychiatric comorbidities and familial confounders. Preliminary results also suggest potential links with dementia, insomnia, respiratory diseases, gastrointestinal diseases, migraine, and chronic pain, but replication is warranted. The risk of death by suicide in OCD is now well established. OCD has also been associated to increased mortality due to natural causes, but more research on specific causes of death is needed. Clarification of the mechanisms behind the observed associations will be critical to inform the rational design of prevention efforts. In the meantime, while OCD symptom reduction remains a priority, clinicians should also focus on monitoring the general health and promoting healthy lifestyles of persons with OCD.

Migraine: A Review on Its History, Global Epidemiology, Risk Factors, and Comorbidities

Migraine affects more than one billion individuals each year across the world, and is one of the most common neurologic disorders, with a high prevalence and morbidity, especially among young adults and females. Migraine is associated with a wide range of comorbidities, which range from stress and sleep disturbances to suicide. The complex and largely unclear mechanisms of migraine development have resulted in the proposal of various social and biological risk factors, such as hormonal imbalances, genetic and epigenetic influences, as well as cardiovascular, neurological, and autoimmune diseases. This review presents a comprehensive review of the most up-to-date literature on the epidemiology, and risk factors, as well as highlighting the gaps in our knowledge.

Determinants of migraine headache among regular undergraduate students, of Wollo University, Dessie, Ethiopia: cross-sectional study

BACKGROUND

The prevalence of migraine headaches varied from 2.4 to 48.5% worldwide among university students. As per the knowledge of the investigators, the study of migraine headaches is not done in this study area. Hence, this study aimed to assess determinates of migraine headaches among regular undergraduate students, of Wollo University, Dessie, Ethiopia, 2020.

METHOD

Institution-based cross-sectional study design was conducted from November 15-30 /2020 by using a self-administered questionnaire among 371 regular undergraduate students at Wollo University. A multistage sampling technique was employed to represent our study population. Identity migraine test, Migraine Disability Assessment Questionnaire, perceived stress scale, and Oslo social support scale was used. Descriptive statistics, binary and multiple logistic regression were employed. The adjusted odds ratio at a 95% confidence interval and level of significance (p-value < 0.05) was used to interpret the findings.

RESULTS

From 371 participants, the prevalence of migraine headache in this study was 34% (95% CI: 29.2, 38.5). Variables statistically associated with migraine headache, were a family history of headache (AOR = 3.83, CI: 2.313, 6.366), suicidal thoughts in the past 3 months (AOR = 10.76, CI: 2.117, 54.74), and had low perceived stress 62.6% (AOR = 0.374, CI: 0.205, 0.683).

CONCLUSION

In this study, the prevalence of migraine headaches was very high. Family history of headache, suicidal thoughts, and low perceived stress were determinates for migraine headache. So special emphasis shall be given to those participants who had high perceived stress, a family history of migraine headache, and suicidal thoughts.

A Bio-Psychosocial Framework for Chronic Daily Headaches: A Mixed Methods Study

Chronic daily headaches (CDH) are primarily understood from a psychophysiological formulation. A broad biopsychosocial understanding, where there is equal importance given to biological, psychological and socio-cultural factors, is underexplored in headache. Socio-cultural factors, such as gender, socio-economic factors can perpetuate and worsen the condition. For an effective and sustainable intervention, these factors need to be considered. The current study aims to explore and develop a biopsychosocial framework for headache disorders. A convergent parallel mixed methods design was used and participants were recruited from a tertiary referral care hospital, Bengaluru, India. Headache Assessment Sheet, GAD 7, HDRS, PSS and B COPE were used in the quantitative phase. The data was analysed using r software. Qualitative phase of the study, in depth interview guide was used and data analysed thematically. Quantitative phase, 38 participants were recruited. The average age, was 38.02 (±10.17), majority of the participants being females 31 (81.58%). The mean duration of illness was 8.63 (±4.73) years. The anxiety scores positively correlated with pain intensity (r = 0.50 at P ≤ .001) and the median anxiety scores varied with photophobia (P ≤ .03). The anxiety scores correlated with PSS (r = 0.428 at P ≤ .007) and HDRS (r = 0.428 at P ≤ .007) scores. Gender variations in coping were seen, avoidant coping having higher median scores in women. (P ≤ .08). In qualitative phase of the study, six participants were recruited. Three main themes emerged from the qualitative phase of the study: headache - an illness, headache factors and the impact. Chronic daily headaches are influenced by biological, psychological, environmental and socio-cultural factors. A bio-psychosocial framework will help to understand and develop targeted interventions.

COVID-19 pandemic impact on headache in healthcare workers: a narrative review

Background: Pandemic of COVID-19, the potentially fatal disease caused by SARS-CoV-2, had caused intangible consequences on global health systems, economy, daily life, education, travel, leisure, work, and mental health. Its impact on mental and physical health, especially in health professionals, has been described. Objective: This study aimed to review and discuss the published evidence regarding the presence of headache on COVID-19 healthcare workers. Methods: In this review, we searched for all articles published in various data bases including PubMed / Medline, Scopus, and Web of Science and all original research studies, letters to editor, case reports, commentaries and reviews published in English, Portuguese or Spanish were searched. Two researchers independently analyzed published articles in order to include/exclude based on inclusion or exclusion criteria.  Results: Thirteen articles were included.  All studies included in this review were observational; eleven were cross-sectional studies, one was a prospective/cohort and one was a retrospective. Two studies evaluated psychological outcomes, mental health disorders and associated factors, one study investigated symptoms and causes of somatic symptom disorder and all other studies evaluated headaches associated with Personal Protective Equipment (PPI). Conclusions: The present review shows that COVID-19 pandemic has negative impact on physical and mental health in healthcare workers and headache has been associated to psychological stress and work overload during pandemic.  Further studies are necessary to better investigate COVID-19 pandemic effects on headaches and other neurological conditions.

Primary headaches among gender dysphoric female-to-male individuals: A cross-sectional survey on gender transition experience

OBJECTIVE

To investigate the frequency, attack characteristics, and treatment experiences of migraine and tension-type headache (TTH) among gender dysphoric female-to-male (FtM) participants as well as in relation to psychiatric comorbidities and real-life experience that relates to being transgender in Turkey.

BACKGROUND

There are only a few publications to date on transgender individuals with headache. Further studies to understand the distinctive needs might provide better management.

METHODS

A total of 88 gender dysphoric FtM individuals (mean (SD) age: 24.8 (5.7) years) were included on a voluntary basis in this cross-sectional survey. Each participant filled out the questionnaire form that elicited items on sociodemographic characteristics, Gender Identity Transition Inventory, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and Headache Questionnaire.

RESULTS

Overall, 32/88 (36.4%; 95% confidence interval [CI]: 27.0%-47.0%) participants were diagnosed with migraine, and 36/88 (40.9%; 95% CI: 31.5%-52.3%) participants were diagnosed with TTH. High rates of unemployment, smoking, and social drinking were observed in our sample compared with the general population in Turkey. The three-item ID migraine screener was positive in 20.5% (18/88 patients) of our population. Patients with migraine in comparison with patients with TTH had statistically significantly higher BDI [12.0 (1-50) vs. 7.0 (0-33); p = 0.013] and BAI [13 (1-48) vs. 5 (0-22); p = 0.016] scores, longer headaches in the past month [median 3 vs. 1 day; p < 0.001], higher Numerical Rating Scale scores for headache severity [7 (2-10) vs. 5 (1-9), p < 0.001], and higher likelihood of menstruation acting as a triggering factor [8/32 patients (25.0%) vs. 0/36 patients (0.0%); p = 0.001] as well as increased rates of previously given diagnosis by a physician [15/32 patients (46.9%) vs. 4/36 patients (11.1%); p < 0.001], a greater number of neuroimaging tests being performed [12/32 patients (37.5%) vs. 3/36 patients (9.1%); p = 0.012], and a higher rate of emergency room utilization [7/32 patients (21.9%) vs. 1/36 patients (2.8%); p = 0.039] for headache.

CONCLUSIONS

In the FtM transgender population we investigated, migraine and TTH were quite common. The screening and early recognition of comorbid migraine, as well as the comorbid depression and anxiety, seem to be important in gender dysphoric FtM individuals. Further studies are needed to better understand the potential interaction of migraine with comorbid psychiatric disorders and the prevalence of headache types and gender-affirmative hormone treatment outcomes in the transgender population.

Comorbidities of primary headache disorders: a literature review with meta-analysis

Background

Primary headache disorders are common and burdensome conditions. They are associated to several comorbidities, such as cardiovascular or psychiatric ones, which, in turn, contribute to the global burden of headache. The aim of this study is to provide a comprehensive description of the pooled prevalence of comorbidities of primary headache disorders using a meta-analytical approach based on studies published between 2000 and 2020.

Methods

Scopus was searched for primary research (clinical and population studies) in which medical comorbidities were described in adults with primary headache disorders. Comorbidities were extracted using a taxonomy derived from the Global Burden of Disease (GBD) study. We compared prevalence of comorbidities among headache sufferers against general population using GBD-2019 estimates, and compared comorbidities’ proportions in clinical vs. population studies, and by age and gender.

Results

A total of 139 studies reporting information on 4.19 million subjects with primary headaches were included: in total 2.75 million comorbidities were reported (median per subject 0.64, interquartile range 0.32–1.07). The most frequently addressed comorbidities were: depressive disorders, addressed in 51 studies (pooled proportion 23 %, 95 % CI 20–26 %); hypertension, addressed in 48 studies (pooled proportion 24 %, 95 % CI 22–26 %); anxiety disorders addressed in 40 studies (pooled proportion 25 %, 95 % CI 22–28 %). For conditions such as anxiety, depression and back pain, prevalence among headache sufferers was higher than in GBD-2109 estimates. Associations with average age and female prevalence within studies showed that hypertension was more frequent in studies with higher age and less females, whereas fibromyalgia, restless leg syndrome, and depressive disorders were more frequent in studies with younger age and more female.

Conclusions

Some of the most relevant comorbidities of primary headache disorders – back pain, anxiety and depression, diabetes, ischemic heart disease and stroke – are among the most burdensome conditions, together with headache themselves, according to the GBD study. A joint treatment of headaches and of these comorbidities may positively impact on headache sufferers’ health status and contribute to reduce the impact of a group of highly burdensome diseases.

Clinical Profile of Migraine in a Rural Population Presenting to Tertiary Care Hospital in North India

Background and Objective:

Migraine is one of the most common types of headache leading to significant disability; still people do not seek early help in developing countries. Therefore, we planned to conduct a study to assess the clinical profile of migraine, its triggers, comorbidities, and related disability in rural India.

Design:

An observational study in which 1,245 men and women suffering from migraine were recruited at a tertiary care hospital and were asked to complete a questionnaire related to migraine, its triggers, comorbidities, and disability.

Results:

Out of 1245 patients, females constituted 75% (937) of the patient pool and rest 25% were males (308). Fatigability (52.7%), nausea/vomiting (42.7%), phonophobia (33.57%), numbness (28.2%), and vertiginous sensation (20.8%) were accompanying features. Stress was the most common trigger impacting 44.9% of the patient population, followed by noise in 44.3% of cases. Exertion and sleep disturbance acted as triggers in 36.1%, smells in 20.5%, hormonal factors in 11.5%, and visual stimuli in 5.1% of patients. Anxiety was identified as the most common comorbidity affecting 542 patients (43.5%), followed by depression in 25.7%of patients. Around 103 patients (8.2%) had other psychiatric illnesses such as panic disorder and bipolar mood disorder.

Conclusion:

The migraine-related disability is high; therefore we conducted a study to understand its triggers and clinical profile. This was the first observational study conducted in a tertiary care hospital on migraine in north India catering to a sizeable rural population however, larger population studies are required to understand migraine more exhaustively.

Altered functional connectivity of the insula in a rat model of recurrent headache

Migraine is a pain disorder accompanied by various symptoms. The insula, a “cortical hub,” is involved in many functions. Few studies have focused on the insula in migraine. We explored the resting-state functional connectivity between the insula and other brain areas in rats subjected to repeated meningeal nociception which was commonly used as animal model of migraine. Inflammatory soup was infused through supradural catheters in conscious rats. The rats were subdivided based on the frequency of the inflammatory soup infusions. Magnetic resonance imaging data were acquired on rats 21 days after inflammatory soup infusion and functional connectivity seeded on the insula was analyzed. In the low-frequency inflammatory soup group, magnetic resonance imaging was performed again 1 h after the glyceryl trinitrate injection following baseline scanning. The cerebellum showed increased functional connectivity with the insula in the inflammatory soup groups. The insula showed increased functional connectivity with the medulla and thalamus in the ictal period in the low-frequency inflammatory soup rats. In the high-frequency inflammatory soup group, several areas showed increased functional connectivity with the insula, including the pons, midbrain, thalamus, temporal association cortex, and retrosplenial, visual, and sensory cortices. Our findings support the hypothesis that the headache phase of migraine depends on the activation and sensitization of the trigeminovascular system, and that the chronification of migraine may be related to higher brain centers and limbic cortices. The insula may be a new target for treatment of migraine.

The Prevalence of Migraine With Anxiety Among Genders

Objective: The aims of the present systematic review were to explore the prevalence of migraine with anxiety exclusively and determine if and why there are likely to be differences across genders. Introduction: Migraine is a very common neurological disorder and cause of productive disability worldwide that is more frequent in women of childbearing age than males. Previous studies have frequently demonstrated comorbidity of migraine and other psychiatric disorders. Although the prevalence of migraine across gender is well-established there are few if any systematic reviews on the prevalence of migraine comorbidity with anxiety cross-genders. Methods: The present systematic review included prevalence studies, clinic-based and cohort studies that reported the frequency of migraine with anxiety within the study sample. Eleven studies were included in the review after screening by two independent reviewers. Studies included participants who were 16 years and older diagnosed with migraine. Results: The main findings of this review indicated that anxiety is a major comorbidity of migraine worldwide, with a wide range (16-83%) of prevalence and a mean of ~43% of patients experiencing comorbid symptoms. Subjective anxiety symptoms appear to be greater among males with migraine than females which could be attributable to both environmental and/or hormonal and genetic predispositions. Conclusions: The results reemphasize the high prevalence of migraine and comorbid anxiety symptoms worldwide while showing that although migraine is far more prevalent among women in general co-morbidity of migraine with anxiety unfolds a different gender difference. The results highlight the significance of exploring the impact of existing and pre-existing comorbid conditions of patients with migraines and further consideration into their diagnostic and treatment strategies.

Clinical Reasoning Behind Non-Pharmacological Interventions for the Management of Headaches: A Narrative Literature Review

Headache is the clinical syndrome most commonly observed by neurologists in daily practice. Pharmacological and non-pharmacological treatments are commonly used for the management of headaches; however, the clinical reasoning behind these interventions is not properly applied. We conducted a narrative literature review using as data sources for academic PubMed, MEDLINE, EMBASE, AMED, CINAHL, EBSCO, PEDro, Cochrane Database of Systematic Reviews, Cochrane Collaboration Trials Register, and SCOPUS. This narrative literature review mainly considered systematic reviews, meta-analyses, randomised clinical trials, and expert opinions published after the year 2000 discussing clinical reasoning for application of non-pharmacological interventions in individuals with tension-type, migraine, and cervicogenic headaches. After the data extraction, we organized the literature thematically as follows: (1) mapping of theoretical aspects of non-pharmacological interventions; (2) summarizing most updated literature about effectiveness of non-pharmacological interventions grouped by targeted tissue and headache; (3) identifying research gaps in the existing literature and proposing hypotheses for better understanding of current clinical reasoning. We found that there are many non-pharmacological treatment strategies used for headaches, including beyond the tissue-based impairment treatments (bottom-up) and strategies targeting the central nervous system (top down). Bottom-up strategies include joint-biased, soft-tissue biased, or needling interventions, whereas top-down strategies include exercise and cognitive interventions. Evidence shows that the effectiveness of these interventions depends on the application of proper clinical reasoning, since not all strategies are effective for all headaches. For instance, evidence of non-pharmacological interventions is more controversial for migraines than for tension-type or cervicogenic headaches, since migraine pathogenesis involves activation of sub-cortical structures and the trigemino- vascular system, whereas pathogenesis of tension-type or cervicogenic headaches is most associated to musculoskeletal impairments of the cervical spine. We conclude that current literature suggests that not all non-pharmacological interventions are effective for all headaches, and that multimodal, not isolated, approaches seem to be more effective for patients with headaches. Most published studies have reported small clinical effects in the short term. This narrative literature review provides some hypotheses for discrepancies in the available literature and future research. Clinical reasoning should be applied to better understand the effects of non-pharmacological interventions.

Current perspectives on sex differences in tension-type headache

INTRODUCTION

Clinical and experimental evidence supports the presence of several gender differences in the pain experience.

AREAS COVERED

The current paper discusses biological, psychological, emotional, and social differences according to gender and their relevance to TTH. Gender differences have also been observed in men and women with tension-type headache and they should be considered by clinicians managing this condition. It appears that multimodal treatment approaches lead to better outcomes in people with tension-type headache; however, management of tension-type headache should consider these potential gender differences. Different studies have observed the presence of complex interactions between tension-type headache, emotional stress, sleep, and burden and that these interactions are different between men and women.

EXPERT OPINION

Based on current results, the authors hypothesize that treatment of men with tension-type headache should focus on the improvement of sleep quality and the level of depression whereas treatment of women with TTH should focus on nociceptive mechanisms and emotional/stressful factors. Future trials should investigate the proposed hypotheses.

[Possibilities of using Cytoflavin in the treatment of cognitive and emotional disorders in patients with tension headaches]

OBJECTIVE

To evaluate the efficacy and safety of Сytoflavin in the treatment of cognitive and emotional disorders in patients with tension headache.

MATERIAL AND METHODS

Fifty patients with tension headache, aged from 18 to 50 years, were studied. The following methods and tests were used: neurological examination, NPRS, STAI, CFQ, RAVLT, TOVA, electroencephalography (routine and spectral analysis). The patients were treated with Сytoflavin.

RESULTS

After the treatment, clinical improvement was observed in 62.0% of the patients. A significant decrease in trait anxiety and inattention, as well as an improvement of memory performance were observed. A comparative analysis of neurophysiological results before and after the treatment showed a decrease in the manifestations of dysfunction of nonspecific regulation of the brain.

CONCLUSION

The results of this study demonstrate the efficacy of Cytoflavin in the treatment of tension headache and associated emotional and cognitive impairments.

Comparison of patients with migraine and tension-type headache in terms of somatosensory amplification and health anxiety

INTRODUCTION

Although it is known that anxiety and depressive disorders frequently accompany migraine and TTH, the role of somatic amplification (SSA) and health anxiety in these diseases is not adequately known.

OBJECTIVE

The aim of this study is to compare SSA and health anxiety in patients with migraine or TTH, and healthy controls and to investigate the relationships between SSA, health anxiety, headache characteristics, anxiety and depressive symptoms.

METHODS

Fifty-four migraine, 50 TTH patients from the outpatient unit of the neurology department and 53 healthy volunteers were recruited for the study. The somatosensory amplification scale (SSAS), health anxiety inventory, Beck depression (BDI) and anxiety inventory (BAI) were administered to all participants.

RESULTS

The SSAS scores were significantly higher in migraineurs compared with the healthy controls. The health anxiety scores were significantly higher in both migraine and TTH groups. The BDI and BAI scores were also significantly higher in migraine and TTH groups compared with the controls. A significant positive correlation was found between headache frequency and BAI scores, the visual analogue scale scores and SSAS and BDI scores in migraineurs. The SSAS scores were also significantly correlated with the BDI and BAI scores in both of the headache groups. A similar correlation was determined with the health anxiety scores.

CONCLUSIONS

While patients with migraine and TTH evalute, taking into account the SSA and health anxiety may contribute to the prognosis and treatment of these diseases.

Gender differences in clinical and psychological variables associated with the burden of headache in tension-type headache

Our aim was to assess gender differences in variables associated with the emotional and physical burdens of tension-type headache (TTH). Participants with TTH diagnosed according to the ICHD-III were recruited from three university-based hospitals (in Spain, Italy, Denmark) between January 2015 and June 2017. The physical/emotional headache burden was assessed with the Headache Disability Inventory (HDI-P/HDI-E, respectively). Headache features were collected with a four-week diary. Sleep quality was assessed with Pittsburgh Sleep Quality Index. The Hospital Anxiety and Depression Scale evaluated anxiety and depressive symptom levels. Trait and state anxiety levels were evaluated with the State-Trait Anxiety Inventory. Two hundred and twelve (28% men) participants (aged 41-48 years old) participated. Multiple regression models revealed that sleep quality explained 36.7% of the variance of HDI-E and 31.1% of the variance of HDI-P in men, whereas headache intensity, depressive levels, and younger age explained 37.5% of the variance of HDI-E and 32.8% of the variance of HDI-P in women (all p < .001). This study observed gender differences in variables associated with headache burden in TTH. Management of men with TTH should focus on interventions targeting sleep quality, whereas the management of women with TTH should combine psychological approaches and interventions targeting pain mechanisms.

Depression Among Patients with Chronic Cluster Headaches

Introduction: Chronic headaches account for a significant proportion of people leading a poor quality of life. Chronic cluster headaches can be defined as episodes of headache usually around the eye in the pattern of a cluster lasting 15-180 minutes each followed by multiple similar episodes occurring at a frequency of 1-8 times per day.

Method: This cross-sectional study was conducted in Jinnah Postgraduate Medical Center, Karachi. One hundred patients who were diagnosed cases of chronic cluster headaches were asked to fill the Beck Hopelessness Scale (BHS), Headache Impact Test (HIT), and Hospital Anxiety and Depression Scale (HADS).

Results: Of our study subjects, 57 were males and 43 were females. The mean HIT-6 score among these patients was found to be 60.5±7.67 (p-value = 0.04). The mean BHS score among these patients was found to be 13±6.87. The mean HADS reporting anxiety (HADS-A) was found to be 12.54 ± 5.65; whereas, the mean HADS reporting depression (HADS-D) was found to be 7.65 ± 4.65.

Conclusion: Patients with chronic cluster headaches have higher scores than the general population. There is an association between headache syndromes and depression which require further investigation.

Atypical functional connectivity between the anterior cingulate cortex and other brain regions in a rat model of recurrent headache

We explored the atypical functional connectivity between the anterior cingulate cortex and other brain areas in rats subjected to repeated meningeal nociception. The rat model was established by infusing an inflammatory soup through supradural catheters in conscious rats. Rats were subdivided according to the frequency of the inflammatory soup infusions. Functional connectivity analysis seeded on the anterior cingulate cortex was performed on rats 21 days after inflammatory soup infusion. Glyceryl trinitrate was injected following baseline scanning in the low-frequency inflammatory soup group and magnetic resonance imaging data were acquired 1 h after the injection. The rats exhibited nociceptive behavior after high-frequency inflammatory soup infusion. The anterior cingulate cortex showed increased functional connectivity with the cerebellum in the inflammatory soup groups. The medulla showed increased functional connectivity with the anterior cingulate cortex in the ictal period in the low-frequency inflammatory soup rats. Several areas showed increased functional connectivity with the anterior cingulate cortex in the high-frequency inflammatory soup group, including the pontine tegmentum, midbrain, thalamus, corpus callosum, hippocampus, and retrosplenial, visual, sensory, and motor cortices. This study indicated that the medulla participates in the early stage of a migraine attack and may be associated with the initiation of migraine. Sensitization of the trigeminal nociceptive pathway might contribute to the cutaneous allodynia seen in chronic migraine. Brain areas important for memory function may be related to the chronification of migraine. Electrophysiological studies should examine those migraine-related areas and provide new targets for migraine treatment and prevention.

Understanding the nature of psychiatric comorbidity in migraine: a systematic review focused on interactions and treatment implications

BACKGROUND

Migraine is a highly prevalent and disabling neurological disorder which is commonly linked with a broad range of psychiatric comorbidities, especially among subjects with migraine with aura or chronic migraine. Defining the exact nature of the association between migraine and psychiatric disorders and bringing out the pathophysiological mechanisms underlying the comorbidity with psychiatric conditions are relevant issues in the clinical practice.

METHODS

A systematic review of the most relevant studies about migraine and psychiatric comorbidity was performed using "PubMed", "Scopus", and "ScienceDirect" electronic databases from 1 January 1998 to 15 July 2018. Overall, 178 studies met our inclusion criteria and were included in the current review.

RESULTS

According to the most relevant findings of our overview, the associations with psychiatric comorbidities are complex, with a bidirectional association of major depression and panic disorder with migraine. Importantly, optimizing the pharmacological and non-pharmacological treatment of either migraine or its psychiatric comorbidities might help clinicians to attenuate the burden of both these conditions.

CONCLUSIONS

The available data highlight the need for a comprehensive evaluation of psychiatric disorders in migraine in order to promote an integrated model of care and carefully address the burden and psychosocial impairment related to psychiatric comorbidities in migraine.

Efficacy of psychological treatment for headache disorder: a systematic review and meta-analysis

BACKGROUND

Headache disorder is not only a common complaint but also a global burden. Pharmacotherapeutic and non-pharmacotherapeutic approaches have been developed for its treatment and prophylaxis. The present study included a systematic review of psychological treatments for primary headache disorder accessible in Korea.

METHODS

We included English and Korean articles from EMBASE, MEDLINE, Cochrane library database, SCOPUS, ScienceDirect, Web of Science, CINAHL, PsycArticles and Korean database, KoreaMed and KMBASE which studied primary headache and medication-overuse headache. The primary efficacy measure was the number of headache days per month, while secondary efficacy measures were the number of headache attacks per week, headache index, treatment response rate, and migraine disability assessment. The meta-analysis was performed using R 3.5.1. to obtain pooled mean difference and pooled relative risk with 95% confidence interval (CI) for continuous data and dichotomous data, respectively.

RESULTS

From 12,773 identified articles, 27 randomized clinical trials were identified. Primary outcome showed significant superiority of psychological treatments (pooled mean difference = - 0.70, 95% CI [- 1.22, - 0.18]). For the secondary outcomes, the number of headache attacks (pooled mean difference = - 1.15, 95% CI [- 1.63, - 0.67]), the headache index (pooled mean difference = - 0.92, 95% CI [- 1.40 to - 0.44]) and the treatment response rate (pooled relative risk = 3.13, 95% CI [2.24, 4.37]) demonstrated significant improvements in the psychological treatment group over the control group.

CONCLUSION

Psychological treatments for primary headache disorder reduced headache frequency and the headache index. Future research using standardized outcome measures and strategies for reducing bias is needed.

Cognitive impairment in patients with migraine: causes, principles of effective prevention and treatment

Cognitive impairment (CI) is common in patients with migraine; its causes and pathogenesis continue to be discussed. Some authors consider that migraine proper does not lead to decreased cognitive functions, neuroimaging changes in the brain white matter are asymptomatic in migraine; and CI in patients with this condition is caused by comorbidities (depression, anxiety disorder) and/or concurrent cerebrovascular and neurodegenerative diseases. Other authors report the pathogenetic role of migraine in the development of CI and the importance of the frequency of headache attacks and neuroimaging changes in the brain matter in migraine. The paper reviews clinical trials dealing with the prevalence, causes, and pathogenesis of CI in patients with migraine. It sets forth the current principles of prevention and treatment of CI in patients with this condition.

[Depressive disorders in primary care: Clinical features and sociodemographic characteristics]

INTRODUCTION

Our aim was to determine the reason for consultation and the clinical features of depressive disorders according to the diagnostic and statistical manual (DSM) 4th edition IV R in primary care and to identify if there is an association between sociodemographic characteristics and depressive pattern.

MATERIALS AND METHODS

In a cross-sectional study conducted to determinate the prevalence of depressive disorders in primary care, at three urban centers in two cities Salé and Oujda by five physicians, we recruited primary care 396 patients of whom 58 were depressed, among these patients we screened for depressive disorders, their clinical features, the melancholic characteristics and suicidal ideation using the Mini International Neuropsychiatric Interview.

RESULTS

Mean age of the 58 depressive patients was 46±15 years. They were predominantly female, inactive and of low socio-economic level. Approximately one-third of the patients were illiterate and single. The symptoms frequently encountered were sadness (63.7%), anhedonia (62%), insomnia (45.7%), anorexia (60.9%), psychomotor retardation (60.9%) and asthenia (73.9%). Somatic symptoms were present 99%, the most common complaint was pain that exhibited 68.6% prevalence. Suicidal ideations were found in 36.2% of these depressive patients.

CONCLUSION

The accuracy of the clinical features of patients with depression in primary care will facilitate the detection of these disorders by general practitioners and improve management of depression.

Frequency of Primary Headache Syndromes in Patients with a Major Depressive Disorder

Purpose The primary objective of this study was to assess the overall frequency of primary headaches in subjects with a moderate to severe major depressive disorder. A further objective was to determine the frequency of primary headache sub-types in this population. Materials and methods This descriptive, cross-sectional study was conducted at the outpatients' clinic of the department of psychiatry, Pakistan Railways Teaching Hospital, an affiliate of Islamic International Medical College, Rawalpindi. The duration of the study was from December 2016 to May 2017. One hundred and ten consecutive patients with a major depressive disorder (MDD) were assessed for a primary headache, according to the diagnostic criteria of International Classification of Headache Disorders second edition (ICHD-2). MDD patients with moderate to severe depression according to the diagnostic and statistical manual of mental disorders (DSM-5) were enrolled in the study. A semi-structured proforma was designed to gather information on sociodemographic variables. The data was analyzed by utilizing Statistical Package for Social Sciences, version 22 (IBM Corp., Armonk, NY, US). Results Of the 110 MDD patients enrolled, a primary headache was present in 45 (40.90%) cases. Additionally, five of these patients had a migraine with aura (11.11%), 12 had a migraine without aura (26.66%), and 28 had a tension-type headache (62.22%). In the females, migraines with or without aura was frequent (35.29%), while a tension-type headache was more common in males (72.72%). Conclusion More than one-third of the sample had a primary headache syndrome, which shows a high comorbidity between a migraine and its variants and MDD. There is a need to undertake further studies with larger samples to elucidate this relationship.

Variables associated with sleep quality in chronic tension-type headache: A cross-sectional and longitudinal design

OBJECTIVE

To investigate variables associated at baseline (cross-sectional design) and at one year (longitudinal design) with the quality of sleep in chronic tension-type headache (CTTH).

METHODS

One hundred and eighty (n = 180) and 135 individuals with CTTH participated in the cross-sectional and longitudinal design respectively. Clinical features were collected with a 4-weeks headache diary at baseline and one-year follow-up. Sleep quality was assessed at baseline and 1-year follow-up with the Pittsburgh Sleep Quality Index. Anxiety and depression (Hospital Anxiety and Depression Scale-HADS), burden of headache (Headache Disability Inventory-HDI), quality of life (SF-36 questionnaire), and pressure pain thresholds (PPTs) at trigeminal, extra-trigeminal and widespread area were assessed at baseline. Hierarchical regression analyses were conducted to determine the associations between variables at baseline and 1-year follow-up with sleep quality.

RESULTS

At baseline positive correlations between sleep quality and headache intensity, headache frequency, headache duration, emotional and physical burden of headache and depression were observed. The regression analyses found that depression and emotional burden of headache explained 27.5% of the variance in sleep quality at baseline (r2 = .262; F = 23.72 P < .001). At one-year, sleep quality was significantly associated with baseline burden of headache, depression, widespread PPTs, vitality and mental health domains. Regression analyses revealed that vitality, PPT over the second metacarpal and PPT over the neck explained 30.0% of the variance of sleep quality at one-year (r2 = .269, F = 9.71, P < .001).

CONCLUSIONS

It seems that sleep quality exhibits a complex interaction in individuals with CTTH since depression and the emotional burden were associated with sleep quality at baseline, but vitality and PPTs over extra-trigeminal areas were associated with the quality of sleep at one-year.

Variables Affecting Factors Associated with Primary Headache

Primary headache syndromes’ development is associated with biological, psychological and social parameters. Factors such as daily habits, behavioral characteristics and sleep disorders also play an important role. We aim to identify the variables which affect the above factors. The study included 111 patients affected by primary headache. The patients were stratified into subgroups according to gender, age, occupation and headache type. Women attained higher scores than men in three of the evaluation rating scales and lower scores in the severity of dependence scale. Occupation was associated with SF36 and Hamilton anxiety scale. Unemployed had higher scores in Hamilton anxiety. Migraineurs and occupied individuals have lower SF36 scores. Women are associated with depression, anxiety and higher disability derived from headache. Men are more prone to dependence on opioids. Unemployment was linked with anxiety and well-being. The migraneurs presented a decreased level of quality of life.

Sleep disturbances in tension-type headache and migraine

Current research into the pathogenesis of tension-type headache (TTH) and migraine is focused on altered nociceptive pain processing. Among the potential factors that influence sensitization mechanisms, emotional stress, depression, or sleep disorders all have an essential role: they increase the excitability of nociceptive firing and trigger hyperalgesic responses. Sleep disturbances and headache disorders share common brain structures and pathogenic mechanisms and TTH, migraine, and sleep disturbances often occur together; for example, 50% of individuals who have either TTH or migraine have insomnia. Moreover, insomnia and poor sleep quality have been associated with a higher frequency and intensity of headache attacks, supporting the notion that severity and prevalence of sleep problems correlate with headache burden. It should be noted that the association between headaches and sleep problems is bidirectional: headache can promote sleep disturbances, and sleep disturbances can also precede or trigger a headache attack. Therefore, a better understanding of the factors that affect sleep quality in TTH and migraine can assist clinicians in determining better and adequate therapeutic programs. In this review, the role of sleep disturbances in headaches, and the association with depression, emotional stress, and pain sensitivity in individuals with TTH or migraine are discussed.

The association of headache frequency with pain interference and the burden of disease is mediated by depression and sleep quality, but not anxiety, in chronic tension type headache

BACKGROUND

A better understanding of potential relationship between mood disorders, sleep quality, pain, and headache frequency may assist clinicians in determining optimal therapeutic programs. The aim of the current study was to analyze the effects of sleep quality, anxiety, depression on potential relationships between headache intensity, burden of headache, and headache frequency in chronic tension type headache (CTTH).

METHODS

One hundred and ninety-three individuals with CTTH participated. Headache features were collected with a 4-weeks headache diary. The Hospital Anxiety and Depression Scale was used for assessing anxiety and depression. Headache Disability Inventory evaluated the burden of headache. Pain interference was determined with the bodily pain domain (SF-36 questionnaire). Sleep quality was assessed with Pittsburgh Sleep Quality Index. Path analyses with maximum likelihood estimations were conducted to determine the direct and indirect effects of depression, anxiety, and sleep quality on the frequency of headaches.

RESULT

Two paths were observed: the first with depression and the second with sleep quality as mediators. Direct effects were noted from sleep quality, emotional burden of disease and pain interference on depression, and from depression to headache frequency. The first path showed indirect effects of depression from emotional burden and from sleep quality to headache frequency (first model R 2 = 0.12). Direct effects from the second path were from depression and pain interference on sleep quality and from sleep quality on headache frequency. Sleep quality indirectly mediated the effects of depression, emotional burden and pain interference on headache frequency (second model R 2 = 0.18).

CONCLUSIONS

Depression and sleep quality, but not anxiety, mediated the relationship between headache frequency and the emotional burden of disease and pain interference in CTTH.

Relationship of active trigger points with related disability and anxiety in people with tension-type headache

To investigate the differences in the presence of trigger points (TrPs) and their association with headache-related disability and mood disorders in people with frequent episodic tension-type headache (TTH) (FETTH) and chronic TTH (CTTH). One hundred twenty-two individuals with TTH participated. Clinical features of headache (i.e., intensity, duration, and frequency) were recorded on a headache diary. Headache-related disability was assessed with the Headache Disability Inventory, trait and state anxiety levels with State-Trait Anxiety Inventory, and depression with the Hospital Anxiety and Depression Scale. TrPs were bilaterally explored in the temporalis, masseter, suboccipital, upper trapezius, splenius capitis, and sternocleidomastoid muscles. Sixty-two (51%) patients were classified as FETTH, whereas 60 (49%) were classified as CTTH. Individuals with CTTH showed higher burden of headache and depression than FETTH (P < 0.001). Subjects with FETTH showed similar number of TrPs (total number: 5.9 ± 3.1, active TrPs: 4.7 ± 2.5, and latent TrPs: 1.2 ± 1.9) than those with CTTH (total number: 5.7 ± 3.2, active TrPs: 4.2 ± 3.0, and latent TrPs: 1.5 ± 1.8). The number of active TrPs was significantly associated with the burden of headache (r = 0.189; P = 0.037) and trait anxiety (r = 0.273; P = 0.005): the higher the number of active TrPs, the greater the physical burden of headache or the more the trait anxiety level. No association with the depression was observed. The presence of active TrPs in head and neck/shoulder muscles was similar between individuals with FETTH and CTTH and associated with the physical burden of headache and trait anxiety levels independently of the subgroup of TTH.

Depression and anxiety behaviour in a rat model of chronic migraine

Background

Epidemiological and clinical studies have demonstrated comorbidity between migraine and affective disorders. However, it is unclear whether chronic migraine can lead to affective disorders in other animals.

Methods

A classical chronic migraine rat model (repeated dura mater inflammatory soup [IS] infusion) was used to evaluate depression and anxiety behaviour via weight, sucrose preference test, open field test and elevated plus maze test.

Results

We found that sucrose preference, locomotor and rearing behaviours, inner zoon distance percent, open-arm entries percent and serotonin and dopamine levels in the prefrontal cortex decreased significantly in the IS group compared with those in the control group; co-administration of low-dose amitriptyline ameliorated these deficits. However, no differences in weight, inner zone time percent, or open-arm time percent between the IS and control groups. These results were used to create new depression and anxiety scales to comprehensively assess and evaluate the degree of affective disorders in rats. Most of chronic migraine animals showed depression and anxiety like behaviors but a few didn’t.

Conclusions

Most of the chronic migraine rats were present depression and anxiety like behaviors. The new scales we created are expected to use in the future studies to find out the potential mechanism of affective disorders’ comorbidity.

Neck-Tongue syndrome: A systematic review

Objective Neck-Tongue syndrome (NTS) is characterized by brief attacks of neck or occipital pain, or both, brought out by abrupt head turning and accompanied by ipsilateral tongue symptoms. As the disorder is rare, we undertook a systematic review of the literature to identify all reported cases in order to phenotype clinically the disorder and subsequently inform clinical diagnostic criteria. Methods Two electronic databases were searched using the search term "neck tongue syndrome". All English language references were reviewed in full. Cases were abstracted using a standardized abstraction form and the references of the retrieved articles were reviewed by hand to identify additional references and cases. Conference proceedings from recent headache meetings were searched. We also report six new cases from our centers. Results There were 39 primary cases, 56% of which were female. Mean age (SD) at onset was 16 (12) years. Twenty (53%) experienced neck pain, seven (18%) occipital pain, and 11 (29%) both. Pain was most often sharp or stabbing and severe, lasting several seconds to several minutes. Eleven experienced numbness and/or tingling in the neck/occiput following the pain. Thirty-six had an accompanying tongue sensory disturbance and three a motor/posture disturbance; five had both. Thirteen had other headaches, and four a family history of Neck-Tongue syndrome. Conclusions Neck-Tongue syndrome typically has pediatric or adolescent onset, suggesting that ligamentous laxity during growth and development may facilitate transient subluxation of the lateral atlantoaxial joint with sudden head turning. Familial cases suggest a genetic predisposition in some individuals. Neck-Tongue syndrome should be re-instated in the International Classification of Headache Disorders.

The relative importance of anxiety and depression in pain impact in individuals with migraine headaches

BACKGROUND

Psychological factors are thought to impact headache as triggering, maintaining, and exacerbating factors. A better understanding of the role that modifiable factors, such as anxiety or depression, play in the impact of migraine could help identify potential treatment targets in this population.

OBJECTIVES

The objective of this study was to evaluate the relative importance of anxiety and depression as predictors of the impact of migraine on function. Thus, we aim to understand the relative importance that anxiety and depression have on the impact of migraines by assessing both and some life domains.

METHODS

Cross-sectional study involving forty-three individuals, mostly females (93%), with migraine headaches aged between 20 and 60 years old. Participants answered questions about headache pain intensity at the time of data collection and the usual in the past 30 days (0-10 Numerical Rating Scales) as well as other pain characteristics (i.e., duration, frequency, and duration), headache impact (vitality and social, role, and cognitive functioning), anxiety and depression by using the Hospital Anxiety and Depression Scale.

RESULTS

Anxiety (r=0.56, p<.001), but not depression (r=0.09, p=.59), was significantly associated with headache impact. Thus showing the relative importance that anxiety has on headache impact.

CONCLUSIONS

The findings support a larger role for anxiety than depression in the impact of migraine headaches on patient function. There are a number of mechanisms by which anxiety could potentially influence the impact of headache on patient function, and this study highlights that anxiety could potentially be a trigger of headache activity.

IMPLICATIONS

The findings thus suggest the possibility that treatments that focus on anxiety might be potentially more important for individuals with migraine than treatments that focus on depression, at least with respect to having a beneficial impact on the interference of headache with activity. Research is needed to evaluate the beneficial impact of anxiety treatment in individuals with migraine headaches. Clinicians should evaluate and consider treating, as appropriate and necessary, anxiety in patients with migraine.

Headache symptoms consistent with migraine and tension-type headaches in children with anxiety disorders

OBJECTIVE

To examine the incidence of headache symptoms consistent with migraine and tension-type headache (TTH) in children with anxiety disorders.

METHOD

Parents of children with anxiety disorders (n=27) and children without anxiety disorders (n=36) completed a headache questionnaire based on the International Classification of Headache Disorders (2nd edition) criteria.

RESULTS

Children with anxiety disorders had a higher incidence of headache symptoms consistent with migraine and TTH compared to children without anxiety disorders. Girls with anxiety disorders and children with separation anxiety disorder had a higher incidence of headaches compared to girls without anxiety disorders and children with other anxiety disorders respectively. Children with anxiety disorders and headaches had higher self-reported anxiety symptom severity compared to children with anxiety disorders without headaches and children without anxiety disorders.

CONCLUSION

Findings highlight an overlap in anxiety and headaches in children and warrant further research on factors that contribute to the etiology and maintenance of these co-occurring problems.

Validation of the Generalized Anxiety Disorder-7 (GAD-7) and GAD-2 in patients with migraine

Background

Psychiatric problems have been commonly reported in patients with migraine. This study investigated the reliability and validity of the Generalized Anxiety Disorder-7 (GAD-7) and Generalized Anxiety Disorder-2 (GAD-2) in patients with migraine.

Methods

Subjects were recruited from a headache clinic and a neuropsychologist examined their GAD using the Mini International Neuropsychiatric Interview-Plus Version 5.0.0 (MINI). Subjects completed several instruments, including the GAD-7, the Beck Anxiety Inventory (BAI), the Migraine Disability Assessment Scale (MIDAS), the Headache Impact Test-6 (HIT-6), and the Migraine-Specific Quality of Life (MSQoL).

Results

Among 146 participants, 32 patients (21.9 %) had GAD as determined by the MINI. Cronbach’s α for the GAD-7 and GAD-2 were 0.915 and 0.820, respectively. At a cutoff score of 5, the GAD-7 had a sensitivity of 78.1 %, a specificity of 74.6 %, a positive predictive value (PPV) of 46.3 %, and a negative predictive value (NPV) of 92.4 %. At a cutoff score of 1, the GAD-2 had a sensitivity of 84.4 %, a specificity of 72.8 %, a PPV of 46.6 %, and a NPV of 94.3 %. The scores of the GAD-7 and GAD-2 well correlated with the BAI score, the MIDAS score, the HIT-6 score, and the MSQoL score.

Conclusions

The GAD-7 and GAD-2 are both reliable and valid screening instruments for GAD in patients with migraine.

The Impacts of Migraine among Outpatients with Major Depressive Disorder at a Two-Year Follow-Up

Background

No study has investigated the impacts of migraine on depression, anxiety, and somatic symptoms and remission at the two-year follow-up point among patients with major depressive disorder (MDD). This study aimed to investigate the above issues.

Methods

Psychiatric outpatients with MDD recruited at baseline were investigated at a two-year follow-up (N = 106). The Hamilton Depression Rating Scale, Hospital Anxiety and Depression Scale, and Depression and Somatic Symptoms Scale were used. Migraine was diagnosed according to the International Classification of Headache Disorders, 2^nd edition. The patients were divided into no migraine, inactive migraine, and active migraine subgroups. Multiple logistic regressions were used to investigate the significant factors related to full remission of depression.

Results

Among patients without pharmacotherapy at the follow-up, patients with active migraine had significantly greater severities of anxiety and somatic symptoms as compared with patients without migraine; moreover, patients with active migraine had the lowest improvement percentage and full remission rate. There were no significant differences in depression, anxiety, and somatic symptoms between patients with inactive migraine and those without migraine. Active headache at follow-up was a significant factor related to a lower full remission rate.

Conclusions

Active headache at follow-up was associated with a lower rate of full remission and more residual anxiety and somatic symptoms at follow-up among patients with migraine. Physicians should integrate a treatment plan for depression and migraine for the treatment of patients with MDD.

Neurological soft signs in primary headache patients

Neurological soft signs (NSS) are semeiotic anomalies not assessed by the standard neurological examination, primarily developed in psychiatric settings and recently proposed as potential markers of minor brain circuit alterations, especially the cerebellar-thalamic-prefrontal network. Primary headache patients present with normal neurological examination and frequent psychiatric comorbidity. Aim of this exploratory study consisted in assessing NSS in 20 episodic frequent migraine (MH) and in 10 tension-type headache (ETTH) outpatients compared to 30 matched healthy controls. NSS were assessed by the Heidelberg scale; clinical characteristics and brain MRI were additionally obtained in all patients. NSS were increased by ∼70 and ∼90% in ETTH and MH, respectively, with respect to controls (p<0.001) and the difference remained significant even after controlling for age and education. Headache type and characteristics did not influence NSS presentation, while headache patients with white matter hyperintensities (WMH) at brain MRI had higher NSS scores compared both to normal controls and patients without WMH. NSS identify a subset of primary headache patients sharing the same comorbidities or minimal brain anomalies, suggesting that tailored prophylactic options might apply.

The impact of dyspepsia on symptom severity and quality of life in adults with headache

Background

Dyspepsia and headache frequently co-exist, but the clinical implication of this association is uncertain. We planned to examine the prevalence and impact of dyspepsia in adults with headache.

Methods

A cross-sectional study was conducted in a secondary care setting. Clinical, psychological and health-related quality of life (HRQOL) data were compared between subjects with headache and controls (non-headache subjects). The impact of dyspepsia was analysed further in subjects with headache alone.

Results

280 subjects (93 cases with headache and 187 matched controls) were recruited. The following baseline characteristics of subjects were as follows: mean age 45.0±17.3 years, 57.0% females and ethnic distribution—Malaysian = 45 (48.4%), Chinese n = 24 (25.8%) and Indians n = 24 (25.8%). Headache sub-types among cases with headache were as follows: tension-type headache (TTH) n = 53 (57.0%) and migraine n = 40 (43.0%). Dyspepsia was more prevalent in cases with headache compared to controls (25.8% vs 12.8%, p = 0.011), and headache was independently associated with dyspepsia (OR 2.75, 95% CI 1.39–5.43). Among cases with headache, there was a trend towards a higher prevalence of dyspepsia in those with migraine (27.5%) compared to TTH (24.5%). Subjects with headache and dyspepsia, compared to those with headache alone, had a greater severity of headache symptoms (63.67±22.85 mm vs 51.20 ±24.0 mm VAS, p = 0.029). Overall HRQOL scores were lower in headache subjects with dyspepsia (EQ-5D summary score 0.82±0.18 vs 0.90 ±0.16, p = 0.037 and EQ-5D VAS 62.08±17.50 mm vs 72.62 ±18.85 mm, p = 0.018), compared to those without dyspepsia.

Conclusion

Dyspepsia is associated with more severe headache symptoms and results in a lower HRQOL in patients with headache.

The impacts of migraine and anxiety disorders on painful physical symptoms among patients with major depressive disorder

Background

No study has simultaneously investigated the impacts of migraine and anxiety disorders on painful physical symptoms (PPS) among patients with major depressive disorder (MDD). The study aimed to investigate this issue.

Methods

This open-label study enrolled 155 outpatients with MDD, who were then treated with venlafaxine 75 mg per day for four weeks. Eighty-five participants with good compliance completed the treatment. Migraine was diagnosed according to the International Classification of Headache Disorders. MDD and anxiety disorders were diagnosed using the Structured Clinical Interview for DSM-IV-TR. The visual analog scale (VAS) was used to evaluate the severity of eight PPS. Multiple linear and logistic regressions were used to investigate the impacts of migraine and anxiety disorders on PPS.

Results

Compared with patients without migraine, patients with migraine had a greater severity of PPS at baseline and post-treatment. After controlling for demographic variables and depressive severity, migraine independently predicted the intensities of eight PPS at baseline and four PPS post-treatment. Moreover, migraine independently predicted poorer treatment responses of chest pain and full remission of pains in the head, chest, neck and/or shoulder. Anxiety disorders predicted less full remission of pains in the abdomen and limbs.

Conclusion

Migraine and anxiety disorders have negative impacts on PPS among patients with MDD. Integrating the treatment of migraine and anxiety disorders into the management of depression might help to improve PPS and the prognosis of MDD.

Migraine headaches and mood/anxiety disorders in the ELSA Brazil

OBJECTIVE

To describe the relationship between mood/anxiety disorders and migraine headaches emphasizing the frequency of episodes based in a cross-sectional analysis in the Brazilian Longitudinal Study of Adult Health.

BACKGROUND

It has been suggested that frequency of migraine headaches can be directly associated with the presence of psychiatric disorders.

METHODS

Migraine headaches (International Headache Society criteria) was classified as <1×/month, 1×/month-1×/week, 2-6×/week, and daily. Psychiatric disorders using the Clinical Interview Schedule - Revised were classified in 6 categories: common mental (CMD), major depressive (MDD), generalized anxiety (GAD), panic, obsessive-compulsive (OCD), and mixed anxiety and depressive (MADD) disorders. We performed multivariate logistic models adjusted for age, race, education, marital status, income, and use of selective serotonin reuptake inhibitors.

RESULTS

In our sample, 1261 presented definite migraine and 10,531 without migraine headaches (reference). Our main result was an increase in the strength of association between migraine and MDD as frequency of migraine increased for all sample: odds ratio of 2.14 (95% confidence interval [CI] 1.33-3.43) for <1 episode of migraine/month to 6.94 (95% CI 4.20-11.49) for daily headaches for all sample. Significant associations with migraine were also found for GAD, OCD, MADD, and CMD for total sample: MDD, GAD, OCD, MADD, and CMD for women, and MADD and CMD for men. Among men with daily migraine complaint, we found a significant association between migraine and OCD after correction for multiple comparisons (odds ratio 29.86 [95% CI 4.66-191.43]). Analyzing probable and definite migraine cases together, we replicated the findings in a lower magnitude.

CONCLUSIONS

The increase in migraine frequency was associated with progressively higher frequencies of having mood/anxiety disorders in all samples suggesting for some psychiatric disorders a likely dose-response effect especially for women.

Complementary and conventional medicine use among youth with recurrent headaches

OBJECTIVE

To identify prevalence and patterns of complementary and alternative medicine (CAM) use among youth with recurrent headaches (HA) and evaluate associations with co-occurring health problems and limitations as well as with the use and expenditures for conventional medical care.

METHODS

Variables were constructed for youth aged 10 to 17 by using linked data from the 2007 National Health Interview Survey and the 2008 Medical Expenditures Panel Survey. Bivariate, logistic, and 2-part regression analyses were used.

RESULTS

Of the 10.6% of youth experiencing HA, 29.6% used CAM, rising to 41% for the many HA sufferers who also experienced difficulties with emotions, concentration, behavior, school attendance, or daily activities. Biologically based products (16.2%) and mind-body therapies (13.3%) were most commonly used, especially by the 86.4% of youth with HA experiencing at least 1 other chronic condition. Compared with non-CAM users, youth with HA who used CAM also had higher expenditures for and use of most types of conventional care.

CONCLUSIONS

CAM use is most common among youth with HA experiencing multiple chronic conditions and difficulties in daily functioning. Associations among CAM use, multiple chronic conditions, and higher use of conventional care highlight the need for medical providers to routinely ask about CAM use to meet the complex health needs of their patients and facilitate the optimal integration of care. Research is needed to identify models for coordinating complementary and conventional care within a medical home and to understand the health benefits or risks associated with CAM use in conjunction with conventional treatments for patients with HA.

Comorbidity of Migraine

Migraine is a common neurological disorder and can be severely disabling during attacks. The highest prevalence occurs between the ages of 25 and 55 years. Prior studies have found that migraine occurs together with other illnesses at a greater coincidental rate than is seen in the general population. These occurrences are called "comorbidities". To delineate the comorbidities of migraine is important, because it can help improve treatment strategies and the understanding of the possible pathophysiology of migraine.

Association between somatic amplification, anxiety, depression, stress and migraine

BACKGROUND

The aim of this study is to investigate the associations between migraine related disability and somatosensory amplification, depression, anxiety, and stress.

METHOD

Fifty-five migraine patients who applied to the outpatient unit of the Neurology Department of Acibadem University School of Medicine, Maslak Hospital in Istanbul, Turkey, and twenty-eight subjects without migraine were recruited for the study. The participants were asked to complete a sociodemographic form, Migraine Disability Assessment Scale (MIDAS), Depression Anxiety Stress Scale, Somatosensory Amplification Scale (SSAS).

RESULTS

Somatosensory amplification scores were significantly higher in the migraineurs than in the control group (29.85+/-6.63 vs 26.07+/-7.1; p=0.027). Somatosensory amplification scores and depression scores were significantly higher in migraineurs with moderate and severe disability than in patients with minimal and mild disability (31.7+/-6.4 vs 27.71+/-5.49; p=0.01, 11.27+/-8.7 vs 7.38+/-8.11; p=0.04, respectively). A significant positive correlation was found between the frequency of migraine attacks for at least three consecutive months (MIDAS A scores) and the SSAS scores (r=0.363, p=0.007) in migraineurs. The MIDAS total scores were also significantly correlated with the DASS depression subcale scores (r=0.267, p=0.04), and the DASS stress subscale scores (r=0.268, p=0.05).

CONCLUSION

Psychological factors, and vulnerability to bodily sensations may incease the burden of migraine. We point out that the timely assessing of somatic amplification and the evaluation of mental status would help improve the quality of life of in migraineurs.
