Suicidal ideation and risk factors in Korean migraine patients

Risks of suicide in migraine, non-migraine headache, back, and neck pain: a systematic review and meta-analysis

Objective

To conduct a systematic review and meta-analysis on suicidal ideation, attempts, and death in patients with head, neck, and back pain.

Method

Search was performed using PubMed, Embase, and Web of Science from the date of the first available article through September 31, 2021. A random effects model was used to estimate the pooled odds ratios (ORs) and 95% confidence intervals (95% CI) for the association between suicidal ideation and/or attempt and head, back/neck pain conditions. Articles describing non-migraine headache disorders and death by suicide were also reviewed but not included in the meta-analysis due to an insufficient number of studies.

Results

A total of 20 studies met criteria for systemic review. A total of 186,123 migraine patients and 135,790 of neck/back pain patients from 11 studies were included in the meta-analysis. The meta-analysis showed that the estimated risk of combined suicidal ideation and attempt in migraine [OR 2.49; 95% CI: 2.15-2.89] is greater than that in back/neck pain pain [OR 2.00; 95% CI: 1.63-2.45] compared to non-pain control groups. Risk of suicide ideation/planning is 2 folds higher [OR: 2.03; 95% CI: 1.92-2.16] and risk of suicide attempt is more than 3 folds higher [OR: 3.47; 95% CI: 2.68-4.49] in migraine as compared to healthy controls.

Conclusion

There is an elevated risk of suicidal ideation and attempt in both migraine and neck/back pain patients in comparison to healthy controls, and this risk is particularly higher among migraine patients. This study underscores the critical need for suicide prevention in migraine patients.

Associations of migraines with suicide ideation or attempts: A meta-analysis

Objective

Whether migraine is associated with a higher risk of suicide ideation and/or attempts remains controversial. Therefore, we aimed to evaluate these potential associations in migraine patients by performing a meta-analysis of previously published data.

Methods

We searched for studies published up to 31 June 2022 that compared the risk of suicide ideation/attempt in migraineurs and non-migraineurs in PubMed, EMBASE, and Web of Science databases. Sixteen studies fulfilled the eligibility criteria. We applied Random-effects models to calculate pooled adjusted odds ratios (AORs) and 95% confidence intervals (CIs) in patients with migraine.

Results

Migraine patients were at a significantly increased risk of suicide ideation (AOR 1.33, 95% CI 1.15-1.54) and suicide attempts (AOR 1.70, 95% CI 1.42-2.03). The increase in risk may be greater in adults (>19 years) than in younger individuals.

Conclusion

The available evidence indicates a significant association of migraines with suicide ideation and attempts. Future work should confirm and extend these findings, as well as explore whether they are affected by ethnicity or geography.

Suicidal ideation in mothers of asthmatic children and adolescents in a subspecialty outpatient practice

We aimed to investigate prevalence and factors associated with Suicide ideation (SI) in mothers of asthmatic children. This cross-sectional study included 362 dyads of mothers and children with asthma aged 2 to 14 years who attended two pediatric outpatient clinics in Brazil. We assessed the presence of SI (Self-Report Questionnaire-20), the occurrence of stressful events and maternal social support. The prevalence of SI was 8.6%. Low maternal education, exposure to serious illness, and low perception of social support in its affective–social interaction dimension remained significantly associated with SI in the final model. Thus, life stressors, social support and low maternal education accounted for most of the variation in prevalence of maternal SI. There were no effects of child asthma severity on maternal SI in this study.

Prevalence and Factors Associated With Suicidal Ideation in Medical Students With Migraine

Background: The association between migraine and suicide ideation has been identified. However, the predictive factors of suicidal ideation are still controversial and whether migraine with aura can serve as an independent associated factor is uncertain. This manuscript studied the association between migraine with aura and suicidal ideation and explored the predictive factors for suicidal ideation. Methods: We surveyed 9,057 medical students and included 579 medical students with migraine into our study population. All students completed the General Situation Questionnaire, the Verified Headache Questionnaire, Hamilton Anxiety Scale (24 items), Hamilton Depression Scale (24 items), 36-item Health Survey Brief (SF-36), Headache Impact Text-6 (HIT-6), Test Anxiety Scale (TAS), and Pittsburgh Sleep Quality Index (PSQI). Suicidal ideation was measured by the Self-rating Idea of Suicide Scale (SIOSS). Results: Out of the 579 migraine medical college students, 562 (age 19.6 ± 1.6; 448 women and 114 men) were included in the final study. The positive rate of suicidal ideation was 13.7%. Compared with students suffering from migraine without aura, those having migraine with aura had higher suicidal ideation (p < 0.015). After adjusting for demographic factors and headache characteristics, migraine with aura was found to be independently associated with suicidal ideation. Other independent associated factors include anxiety, depression, test anxiety, sleep, headache, and quality of life. Among these various factors, high quality of life was found to play a protective role against suicidal ideation. Conclusions: Migraine with aura is independently associated with suicidal ideation. Furthermore, anxiety, depression, text anxiety, poor sleep quality, and headache frequency are associated with suicidal ideation among medical college students with migraine.

A population-based examination of suicidality in comorbid generalized anxiety disorder and chronic pain

BACKGROUND

Generalized anxiety disorder (GAD) and chronic pain conditions commonly co-occur, and are both independently associated with suicidality; however, little is known about the impact of chronic pain on suicidality among individuals with GAD. The aim of this study was to examine the associations between comorbid GAD and chronic pain conditions with suicide ideation, plans, and attempts in a population-based sample.

METHODS

We analyzed data from the 2012 Canadian Community Health Survey-Mental Health (CCHS-MH; N = 25,113). Multiple logistic regressions examined the associations between comorbid GAD and chronic pain conditions (i.e., arthritis, migraine, back pain; reference = GAD alone) with suicidality (i.e., ideation, plans, and attempts).

RESULTS

After adjusting for sociodemographics, other psychiatric conditions, and other chronic pain conditions, results indicated that compared to GAD alone, comorbid GAD and migraine was associated with increased odds of suicide ideation and plans (adjusted odds ratio (AOR) range: 2.55-3.00) and comorbid GAD and arthritis was associated with increased odds of suicide attempts (AOR = 4.10, 95% CI [1.05-16.01]).

LIMITATIONS

The cross-sectional nature of the survey design does not permit causal assumptions regarding the emergent associations and the self-report assessment of chronic pain conditions may be associated with response biases.

CONCLUSIONS

Results highlight the burden of chronic pain on suicidality among individuals with GAD. These results emphasize the importance of assessing risk of suicidality among individuals with comorbid GAD and chronic pain conditions, particularly migraine and arthritis.

Association of Suicide Risk With Headache Frequency Among Migraine Patients With and Without Aura

Background: Migraines with aura have been associated with suicide in adolescents and young adults, but the association between suicide and migraine frequency has not been determined. This study investigated suicidal ideation and suicide attempts among patients with varying frequencies of migraines, with and without auras.

Methods: This cross-sectional study analyzed 528 patients aged between 20 and 60 years from a headache outpatient clinic in Taiwan. All patients completed a set of questionnaires, including a demographic questionnaire, the Migraine Disability Assessment questionnaire, the Hospital Anxiety and Depression Scale, the Beck Depression Inventory, and the Pittsburgh Sleep Quality Index. Suicide risk was evaluated by self-reported lifetime suicidal ideation and attempts. Patients were divided into low-frequency (1–4 days/month), moderate-frequency (5–8 days/month), high-frequency (9–14 days/month), and chronic (≥15 days/month) migraine groups. The association between migraine frequency and suicidality was investigated using multivariable linear regression and logistic regression.

Results: The rates of suicidal ideation and suicide attempts were the highest for chronic migraine with aura (ideation: 47.2%; attempts: 13.9%) and lowest in migraine-free controls (2.8%). Migraine frequency was an independent risk factor for suicidal ideation and attempts in patients with aura (both P_trend < 0.001), but not in patients without auras. Migraine aura and depression were associated with higher risks of suicidal ideation and suicide attempts in patients with migraine.

Conclusion: High migraine frequency has a correlation with high suicide risk in patients who experience an aura, but not in other patients with migraine.

Association between socioeconomic attainments and suicidal ideation by age groups in Korea

BACKGROUND:

Suicidal ideation is a strong antecedent of suicidal behavior, associated with increased likelihood of suicide. Thus, suicidal ideation serves to identify which groups are at more risk of suicide and has policy implications for targeting groups to prevent suicide.

AIMS:

A substantial body of research has addressed potential determinants of suicide ideation in Korea. Little attention has been paid, however, to analyzing the extent to which socioeconomic attainments (education, household income, and employment status) are associated with risk of suicidal ideation, drawing on nationally representative data.

METHODS:

Data were drawn from the 2012 Korea Welfare Panel Study (KOWEPS). Among the 12,606 respondents, the findings are based on 1,500 young adults (age 18-35) and 3,469 middle-aged adults (age 36-55) who answered a question about suicidal ideation.

RESULTS:

For young adults, respondents from 2-year and 4-year colleges and higher had lower probabilities of suicidal ideation compared with respondents from high school. People out of the labor force also exhibited an elevated risk of suicidal ideation compared with those in waged employment. Middle-aged adults displayed different patterns. Middle-aged respondents from 4-year colleges or higher had an increased likelihood of suicidal ideation. The likelihood of reporting suicidal ideation was predicted to decrease as household income increased only for middle-aged adults.

CONCLUSIONS:

The information about suicidal ideation was obtained from only one question of self-response, which limits the validity of the suicidal ideation measurement. The cross-sectional setting of the data prevents us from estimating causal relationships. Nevertheless, the findings imply that age-specific policy should be implemented to ameliorate differential risk for suicidal ideation and benefit public mental health in the long run.

Migraine and Suicidal Behaviors: A Systematic Literature Review

OBJECTIVE

The aim of this systematic review was to provide a picture of suicidality (suicide ideation and behavior, both fatal and nonfatal) among indviduals with migraine.

BACKGROUND

Migraine is a leading cause of disability around the world. Migraine may manifest with a number of symptoms, ranging from severe headaches to neurological sensory disturbances. Comorbid psychological conditions, such as depression, have also been linked to chronic migraine.

DATA SOURCES

Articles were retrieved from SCOPUS, PubMed, Proquest, and Web of Science.

SEARCH TERMS

Suicid* AND migrain* in English-language peer-reviewed journals between January 1, 1966 and December 31, 2014.

ELIGIBILITY CRITERIA

Original research papers providing empirical evidence about the potential link between migraine and suicidal behaviors.

RESULTS

Initial search identified 510 papers; the titles and abstracts of 360 unique results were examined for their relevance to the combination of migraine and suicidality. In total, 17 papers reporting original empirical analyses were included in this review.

CONCLUSIONS

Research has empirically documented a link between migraine and suicide ideation and behavior, particularly concerning the subtype of migraine with aura. Overall, nonfatal suicidal behavior among people with migraine has primarily been investigated, with only 2 studies analyzing suicide mortality. In addition, majority of studies originated from the United States or Canada (n=10). Future research should thoroughly define migraine and investigate link between migraine and suicide mortality.

Clinically relevant behavioral endpoints in a recurrent nitroglycerin migraine model in rats

BACKGROUND

This research sought to further validate the rat nitroglycerin (NTG) migraine model by comparing the effects of single versus recurrent NTG episodes on behavioral endpoints that mirror ICHD-3 diagnostic criteria for migraine, and to determine if the altered behavioral endpoints are reduced after administration of sumatriptan.

METHODS

Separate cohorts of rats were administered NTG (10 mg/kg/2 ml) or saline (Experiment 1: single injection; Experiment 2: repeated injections; Experiment 3: repeated injections with sumatriptan [0.0, 0.3 and 1.0 mg/kg/ml] rescue. Behavioral endpoints were assessed 2 h after final NTG administration and included time in light/dark chambers for photophobia and activity, pain facial ratings, and cool (5 °C) and warm (46 °C) tail dip.

RESULTS

The first two experiments demonstrated that repeated (n = 5) but not single NTG injections produced photophobia, decreased activity, and yielded less weight gain than saline injections. Experiment 3 showed that sumatriptan attenuated hypoactivity, reduced facial expressions of pain, and reversed weight alterations in a dose-dependent manner.

CONCLUSIONS

These findings identify numerous clinical homologies of a recurrent NTG rat migraine model that may be useful for screening novel pharmacotherapies.

Association of Migraine Headaches With Suicidal Ideation Among Pregnant Women in Lima, Peru

BACKGROUND

Suicide is a leading cause of maternal death globally, and suicide prevalence rates have been shown to be increased in those with migraine. No previous study has examined the association between migraine and suicidal ideation during pregnancy.

OBJECTIVE

To examine the association between migraine and suicidal ideation among a cohort of pregnant women.

METHODS

A cross-sectional study was conducted among 3372 pregnant women attending prenatal care clinics in Lima, Peru. Suicidal ideation and depression were assessed using the Patient Health Questionnaire-9 (PHQ-9) scale during early pregnancy. Migraine classification (including migraine and probable migraine) was based on International Classification of Headache Disorders-III beta criteria. Multivariable logistic regression analyses were performed to estimate odds ratios (OR) and 95% confidence intervals (95% CI).

RESULTS

Suicidal ideation was more common among those with migraine (25.6%) as compared to those with probable migraine (22.1%, P < .001) or non-migraineurs (12.3%, P < .001). After adjusting for confounders, including depression, those with migraine or probable migraine had a 78% increased odds of suicidal ideation (OR = 1.78; 95% CI: 1.46-2.17), as compared with non-migraineurs. Women with both migraine and depression had a 4.14-fold increased odds of suicidal ideation (OR = 4.14; 95% CI: 3.17-5.42) compared to those with neither condition.

CONCLUSION

Migraine is associated with increased odds of suicidal ideation in pregnant women even when controlling for depression. These findings support the consideration of screening women with comorbid migraine and depression for suicidal behavior during pregnancy.

Osmophobia and allodynia are critical factors for suicidality in patients with migraine

Background

Sensory hypersensitivities are common phenomena in migraine. We examined the role of sensory hypersensitivities on suicidality in patients with migraine.

Methods

Patients with migraine (with or without aura) were consecutively recruited from our headache clinic. We asked them if they experienced photophobia, phonophobia, osmophobia, and allodynia during migraine attack. The Mini International Neuropsychiatric Interview was used to diagnose current major depressive disorder (MDD), current generalized anxiety disorder (GAD) and suicidality.

Results

Among 220 subjects, 25.5 % had current MDD, 17.3 % had current GAD, and 31.8 % had suicidality. Patients with suicidality were more like to have a low household income, chronic migraine (CM), medication overuse headache, high headache intensity, osmophobia, allodynia, high disability, MDD, and GAD than those without suicidality. The strongest risk factor for suicidality by multivariate analyses was osmophobia (adjusted Odds Ratio [AOR] 3.12, 95 % confidence interval [CI] 1.57-6.21, p = 0.001), followed by current MDD (AOR 2.99, 95 % CI 1.33-6.76, p = 0.008), CM (AOR 2.48, 95 % CI 1.21-5.09, p = 0.013), current GAD (AOR 3.11, 95 % CI 1.22-7.91, p = 0.017), and allodynia (AOR 2.72, 95 % CI 1.19-6.21, p = 0.018).

Conclusions

Osmophobia and allodynia are critical factors for suicidality in patients with migraine, after controlling for depression, anxiety, and CM.
