Headaches during pregnancy

Continuous combined oral contraceptive use versus vitamin E in the treatment of menstrual migraine: rationale and protocol of a randomized controlled trial (WHAT!)

BACKGROUND

Currently, there is no evidence-based hormonal treatment for migraine in women. Several small studies suggest a beneficial effect of combined oral contraceptives, but no large randomized controlled trial has been performed. As proof of efficacy is lacking and usage may be accompanied by potentially severe side effects, there is a great need for clarity on this topic.

METHODS

Women with menstrual migraine (n = 180) are randomly assigned (1:1) to ethinylestradiol/levonorgestrel 30/150 μg or vitamin E 400 IU. Participants start with a baseline period of 4 weeks, which is followed by a 12-week treatment period. During the study period, a E-headache diary will be used, which is time-locked and includes an automated algorithm differentiating headache and migraine days.

RESULTS

The primary outcome will be change in monthly migraine days (MMD) from baseline (weeks - 4 to 0) to the last 4 weeks of treatment (weeks 9 to 12). Secondary outcomes will be change in monthly headache days (MHD) and 50% responder rates of MMD and MHD.

CONCLUSIONS

The WHAT! trial aims to investigate effectivity and safety of continuous combined oral contraceptive treatment for menstrual migraine. Immediate implementation of results in clinical practice is possible.

New onset headache during delivery and postpartum: Clinical characteristics of a case series

Introduction

There are abundant studies on headache and migraine in women but few or none about their occurrence during labor, delivery, and postpartum (2 hours after delivery) owing to the low incidence. A headache attack can be debilitating when a woman is trying to manage labor pain. Research at our Women's Headache Center within the Department of Gynecology and Obstetrics has begun to shed light on this potential association.

Methods

For the present study 474 women with singleton pregnancy were enrolled. A headache questionnaire was administered at two time points. Headache history was investigated on admission to prenatal care at 36 weeks gestation. The women were followed by a midwife who monitored labor progression and recorded the onset and features of headache pain. During examination before hospital discharge at 3 days post-delivery, the headache questionnaire was reviewed by a headache specialist who differentiated headache type according to International Classification of Headache Disorders (3rd edition) criteria.

Results

Data analysis showed that 145/474 women had a history of headache: 65/145 (44.82%) reported a diagnosis of migraine. Eight reported experiencing a probable migraine attack (4 with aura) and one reported probable tension-type headache during labor or postpartum. All nine women who reported migraine/headache attack during labor had no previous history of headache or neurological illness. All had vaginal delivery. No onset of headache pain in patients with a previous history of headache was noted during delivery and postpartum.

Discussion

The onset of a headache attack during labor in women who usually do not experience headache suggests other pathogenic mechanisms underlying the attack and merits further study.

Migraine management: Non-pharmacological points for patients and health care professionals

Migraine is a highly prevalent disorder with an enormous burden on societies. Different types of medications are used for controlling both acute attacks and prevention. This article reviews some non-pharmacological recommendations aiming to manage migraine disorder better and prevent headache attacks. Different triggers of migraine headache attacks, including environmental factors, sleep pattern changes, diet, physical activity, stress and anxiety, some medications, and hormonal changes, are discussed. It is advised that they be identified and managed. Patients should learn the skills to cope with the trigger factors that are difficult to avoid. In addition, weight control, management of migraine comorbidities, lifestyle modification, behavioural treatment and biofeedback, patient education, using headache diaries, and improving patients' knowledge about the disease are recommended to be parts of migraine management. In addition, using neuromodulation techniques, dietary supplements such as riboflavin, coenzyme Q10 and magnesium, and acupuncture can be helpful. Non-pharmacological approaches should be considered in migraine management. Furthermore, the combination of pharmacological and non-pharmacological approaches is more effective than using each separately.

Headache: pregnancy and breastfeeding Recommendations of the Spanish Society of Neurology's Headache Study Group

INTRODUCTION

Headache is one of the most common neurological complaints, and is most frequent during reproductive age. As a result, we are routinely faced with pregnant or breastfeeding women with this symptom in clinical practice. It is important to know which pharmacological choices are the safest, which should not be used, and when we should suspect secondary headache. To this end, the Spanish Society of Neurology's Headache Study Grouphas prepared a series of consensus recommendations on the diagnostic and therapeutic algorithms that should be followed during pregnancy and breastfeeding.

DEVELOPMENT

This guide was prepared by a group of young neurologists with special interest and experience in headache, in collaboration with the Group's Executive Committee. Recommendations focus on which drugs should be used for the most frequent primary headaches, both during the acute phase and for prevention. The second part addresses when secondary headache should be suspected and which diagnostic tests should be performed in the event of possible secondary headache during pregnancy and breastfeeding.

CONCLUSIONS

We hope this guide will be practical and useful in daily clinical practice and that it will help update and improve understanding of headache management during pregnancy and breastfeeding, enabling physicians to more confidently treat these patients.

Clinical symptoms of androgen deficiency in men with migraine or cluster headache: a cross-sectional cohort study

Background

To compare symptoms of clinical androgen deficiency between men with migraine, men with cluster headache and non-headache male controls.

Methods

We performed a cross-sectional study using two validated questionnaires to assess symptoms of androgen deficiency in males with migraine, cluster headache, and non-headache controls. Primary outcome was the mean difference in androgen deficiency scores. Generalized linear models were used adjusting for age, BMI, smoking and lifetime depression. As secondary outcome we assessed the percentage of patients reporting to score below average on four sexual symptoms (beard growth, morning erections, libido and sexual potency) as these items were previously shown to more specifically differentiate androgen deficiency symptoms from (comorbid) anxiety and depression.

Results

The questionnaires were completed by n = 534/853 (63%) men with migraine, n = 437/694 (63%) men with cluster headache and n = 152/209 (73%) controls. Responders were older compared to non-responders and more likely to suffer from lifetime depression.

Patients reported more severe symptoms of clinical androgen deficiency compared with controls, with higher AMS scores (Aging Males Symptoms; mean difference ± SE: migraine 5.44 ± 0.90, p <  0.001; cluster headache 5.62 ± 0.99, p <  0.001) and lower qADAM scores (quantitative Androgen Deficiency in the Aging Male; migraine: − 3.16 ± 0.50, p <  0.001; cluster headache: − 5.25 ± 0.56, p <  0.001). Additionally, both patient groups more often reported to suffer from any of the specific sexual symptoms compared to controls (18.4% migraine, 20.6% cluster headache, 7.2% controls, p = 0.001).

Conclusion

Men with migraine and cluster headache more often suffer from symptoms consistent with clinical androgen deficiency than males without a primary headache disorder.

Headache and distress during pregnancy

OBJECTIVE

To determine the prevalence of headache, review variables believed to be associated, and assess distress levels in pregnant women.

METHODS

This is a cross-sectional study conducted on pregnant women who presented to a Training and Research Hospital in Sakarya, Turkey from June 1, 2020 to December 1, 2020. The study group consisted of 600 pregnant women who agreed to take part in the study. Chi-squared test and logistic regression analysis were used to analyze the data. Statistical significance level was accepted as P value of 0.05 or less.

RESULTS

The ages of pregnant women ranged from 19 to 44 years with a mean age of 29.01 ± 5.27 years. Prevalence of headache during pregnancy was found to be 55.7% (n = 334). The number of pregnant women at of distress was found to be 144 (24.0%). There was no difference between women with and without headache and between severity of headache and prevalence of distress (P > 0.05 for each).

CONCLUSION

Headache is an important health issue in pregnant women. There was no relationship between the presence and severity of headache and distress level.

The Impact of Parental Migraine on Children

PURPOSE OF REVIEW

This review surveys our current understanding of the impact of parental migraine on children. Understanding the impact of migraine on others in a family unit is critical to describing the full burden of migraine and to developing psychosocial supportive interventions for patients and their families.

RECENT FINDINGS

Having a parent with migraine is associated with several early developmental features including infant colic. Adolescent children of parents with migraine self-report their parent's migraine interferes with school and activities and events. Further, migraine is perceived to impact the relationship between the parent and child. Having a parent with migraine increases a child's risk of having migraine, and having more severe migraine disease. However, children with migraine whose parent also has migraine appear to receive more early and aggressive treatment. The impact of migraine extends beyond the parent with migraine and influences children across biological, psychological, and social domains.

Migraine and other headache disorders in pregnancy

Migraine prevalence is three times higher in women than in men during fertile years, which is mainly due to sex hormone differences. The majority of women suffering from migraine without aura report improvement of their migraine attacks during pregnancy. Migraine attacks with aura can also improve during pregnancy, but more often remain the same or worsen. Anovulation caused by lactation is generally associated with a decrease in migraine attacks in breastfeeding women. This chapter describes the current knowledge on acute and prophylactic treatment options of migraine and other primary headache disorders during pregnancy and lactation. Further, clinical profiles of secondary headaches during pregnancy and the postpartum period are summarized.

Migraine during pregnancy and in the puerperium

Pregnancy can be seen as a positive time for women migraineurs because the elevated estrogen and endogenous opioid levels raise the pain threshold and the stable hormone levels, which no longer fluctuate, eliminate a major trigger factor for the attacks. In a great majority of cases, indeed, migraine symptoms spontaneously improve throughout pregnancy. Generally, migraine without aura (MO) improves better than migraine with aura (MA), which can occur ex novo in pregnancy more frequently than MO. After childbirth, the recurrence rate of migraine attacks increases, especially during the first month; breastfeeding exerts a protective effect against the reappearance of attacks. Migraine and pregnancy share a condition of hypercoagulability; therefore, attention must be paid to the risk of cardiovascular disorders, like venous thromboembolism and ischemic or hemorrhagic strokes. Some of these diseases can be linked to preeclampsia (PE), a serious complication of pregnancy, characterized by hypertension, proteinuria, or other findings of organ failure. This condition is more common in migraineurs compared with non-migraineurs; furthermore, women whose migraines worsen during pregnancy had a 13-fold higher risk of hypertensive disorders than those in which migraine remitted or improved. Pregnancy is generally recognized to exert a beneficial effect on migraine; nonetheless, clinicians should be on the alert for possible cardiovascular complications that appear to be more frequent in this patient population.

Spinal Cord Stimulation in Pregnant Patients: Current Perspectives of Indications, Complications, and Results in Pain Control: A Systematic Review

Spinal cord stimulation (SCS) has been described as a valuable neuromodulator procedure in the management of chronic medically untreated neuropathic pain. Although the use of this technique has been published in many papers, a question still remains regarding its applicability in pregnant patients. The goal of this paper is to discuss the risks, complications, and results as well as the prognosis of SCS in pregnant patients. We performed a systematic review from 1967 to 2018 using the databases MEDLINE, LILACS, SciELO, PubMed, and BIREME, utilizing language as selection criteria. Eighteen studies that met our criteria were found and tabulated. SCS is a reversible and adjustable surgical procedure, which results in patients that demonstrated a significant effect in the reduction of pain intensity in pregnant patients. The etiologies most frequent were complex regional pain and failed back pain syndromes, which together represented 94% of analyzed cases. The technical complications most frequent were lead migration (3%, n = 1). Regarding the risks, the authors did not show significative factors among the categorical variables that can suggest a teratogenicity, while the maternal risks have been associated to the consequences of technical complications due to, among other factors, improvement of abdominal pressure during pregnancy and delivery. Finally, although there are not significative cohorts of pregnant patients, the procedure is still an effective surgical approach of neuropathic pain associated to lower rates of complications and significative improvement in the quality of life of patients during pregnancy.

Headache and pregnancy: a systematic review

This systematic review summarizes the existing data on headache and pregnancy with a scope on clinical headache phenotypes, treatment of headaches in pregnancy and effects of headache medications on the child during pregnancy and breastfeeding, headache related complications, and diagnostics of headache in pregnancy. Headache during pregnancy can be both primary and secondary, and in the last case can be a symptom of a life-threatening condition. The most common secondary headaches are stroke, cerebral venous thrombosis, subarachnoid hemorrhage, pituitary tumor, choriocarcinoma, eclampsia, preeclampsia, idiopathic intracranial hypertension, and reversible cerebral vasoconstriction syndrome. Migraine is a risk factor for pregnancy complications, particularly vascular events. Data regarding other primary headache conditions are still scarce. Early diagnostics of the disease manifested by headache is important for mother and fetus life. It is especially important to identify “red flag symptoms” suggesting that headache is a symptom of a serious disease. In order to exclude a secondary headache additional studies can be necessary: electroencephalography, ultrasound of the vessels of the head and neck, brain MRI and MR angiography with contrast ophthalmoscopy and lumbar puncture. During pregnancy and breastfeeding the preferred therapeutic strategy for the treatment of primary headaches should always be a non-pharmacological one. Treatment should not be postponed as an undermanaged headache can lead to stress, sleep deprivation, depression and poor nutritional intake that in turn can have negative consequences for both mother and baby. Therefore, if non-pharmacological interventions seem inadequate, a well-considered choice should be made concerning the use of medication, taking into account all the benefits and possible risks.

Imaging of Headache in Pregnancy

Pregnant women are most likely to have primary headaches, such as migraine and tension-type headaches, which can be diagnosed and treated without brain imaging. Primary headaches may even start de novo during pregnancy, especially in the first few months. However, when the headache occurs late in pregnancy or in the peripartum period, secondary causes of headaches need to be considered and evaluated by brain and/or vascular imaging, generally using magnetic resonance techniques. There is considerable overlap between the cerebrovascular complications of pregnancy, including preeclampsia/eclampsia, posterior reversible encephalopathy syndrome (PRES), reversible cerebral vasoconstriction syndrome (RCVS), and both hemorrhagic and ischemic strokes; although, their imaging may be distinctive. Imaging is necessary to distinguish between arterial and venous pathology causing headache in the peripartum patient, as there can be similar presenting symptoms. Mass lesions, both neoplastic and inflammatory, can enlarge and produce headaches and neurological symptoms late in pregnancy.

Hormone-Related Migraine Headaches and Mood Disorders: Treatment with Estrogen Stabilization

Because estrogens and the trigeminal system are inherently linked, prescribers who are treating a woman with a hormonally related mood disorder and migraine headaches should consider hormonal options to optimize the patient's treatment. This article discusses the interrelationships of estrogen, serotonin, and the trigeminal system as they relate to menstrual migraine occurrence and hormone-related mood symptoms. In addition, clinical examples are provided to facilitate the prescribers treating women during reproductive transitions in which declining estrogens are related to their suffering.

Pharmacological treatment of migraine during pregnancy and breastfeeding

Migraine affects up to 25% of women of reproductive age. In the majority of these women, migraine improves progressively during pregnancy, but symptoms generally recur shortly after delivery. As suboptimally treated migraine in pregnancy could have negative consequences for both mother and fetus, the primary aim of clinicians should be to provide optimal treatment according to stage of pregnancy, while minimising possible risks related to drug therapy. Nonpharmacological approaches are always first-line treatment, and should also be used to complement any required drug treatment. Paracetamol is the preferred drug for acute treatment throughout pregnancy. If paracetamol is not sufficiently effective, sporadic use of sumatriptan can be considered. NSAIDs such as ibuprofen can also be used under certain circumstances, though their intake in the first and third trimesters is associated with specific risks and contraindications. Preventive treatment should only be considered in the most severe cases. In women contemplating pregnancy, counselling is essential to promote a safe and healthy pregnancy and postpartum period for the mother and child, and should involve a dialogue addressing maternal concerns and expectations about drug treatment. This Review summarizes current evidence of the safety of the most common antimigraine medications during pregnancy and breastfeeding, and provides treatment recommendations for use in clinical practice.

[Current approaches to treatment of migraine during pregnancy]

Migraine is one of the most common complaints in the majority of pregnant women. Migraine without aura is the most frequent cause of headache. Improvement of this disease is reported in 50-80% of patient. However, about one third of pregnant women have severe prolonged attacks with marked concomitant symptoms and maladaptation that necessarily need treatment. Authors consider the issues of differential diagnosis and principles of management of these patients.

Migraine in pregnancy and lactation

Migraine headache is a significant health problem affecting women more than men. In women, the hormonal fluctuations seen during pregnancy and lactation can affect migraine frequency and magnitude. Understanding the evaluation of headache in pregnancy is important, especially given the increased risk of secondary headache conditions. Pregnancy and lactation can complicate treatment options for women with migraine because of the risk of certain medications to the fetus. This review includes details of the workup and then provides treatment options for migraine during pregnancy and lactation.

Neuroendocrine aspects of migraine in women

Migraine is a complex disabling disease influenced mainly by age and gender during the life span. Neuroendocrine events related to reproductive stages and to the menstrual cycle may cause significant change in the clinical pattern of migraine over time, as a consequence of failure in adaptation higher in women than in men. Indeed, the individual threshold of vulnerability to manifest migraine is modulated by hormonal fluctuations naturally occurring throughout the menstrual cycle and at the time of reproductive transitions. In the present short review, the role of endogenous estrogen at the level of brain circuitries which are involved in multiple cellular, neurochemical and neurophysiological processes associated with migraine will be summarized in the context of reproductive milestones. In addition, some clues to recognize hormonally sensitive women on the basis of their migraine history, i.e. onset, association with menstruation or premenstrual syndrome, course during pregnancy and menopause, will be discussed in order to expand the knowledge of reproductive endocrinology in the management of migraine in women.
