Sex hormone-related polymorphisms in endometriosis and migraine: A narrative review

A Correlation Between Migraine and Endometriosis and Its Clinical Implications-A Systematic Literature Review

Background/Objectives: Migraine and endometriosis are two diseases that are associated with women. Endometriosis is a condition exclusively affecting the female population as it affects the female genital tract, while migraine is a primary headache disorder having the highest prevalence in women of reproductive age. Although, undoubtedly, they are two distinct disorders, some correlations have been suggested considering the epidemiological similarities. Methods: This systematic review aimed to analyze the putative links between those two diseases. Two databases were searched in accordance with the PRISMA guidelines, which led to the inclusion of 28 of the most appropriate studies. The review was registered in PROSPERO. Results: A comprehensive analysis of the existing literature allowed us to distinguish six different aspects: (i) the prevalence of migraine in the course of endometriosis, in general, (ii) when comparing endometriosis patients to healthy individuals, (iii) the relation between different migraine types and endometriosis, (iv) pain symptoms in patients with endometriosis and migraine, and finally, (v) molecular and (vi) genetic bases of the suspected correlation. Conclusions: Although not all results are definitely apparent, the results showed a higher prevalence of endometriosis and migraine together than both diseases separately. More precisely, chronic migraine was demonstrated to be the most possibly linked to endometriosis. Moreover, pain symptoms were usually more evident in patients suffering from both diseases at the time. Finally, some suggestions were presented due to this comorbidity's molecular and genetic bases; however, the literature, especially on this topic, is lacking.

Menopause, Perimenopause, and Migraine: Understanding the Intersections and Implications for Treatment

Migraine affects women three times more often than it does men, and various mechanisms may explain this incidence, including the key role of female sex hormones. Fluctuations in the levels of these hormones and their feedback control regulate the menstrual cycle, pregnancy, puerperium, perimenopause, and menopause. They can influence the occurrence and severity of migraine throughout the reproductive period. Of particular importance seems to be the perimenopausal period, which is associated with an increase in migraine, especially menstrual migraine, which is considered more disabling and less amenable to treatment than non-menstrual attacks. This article reviews the available evidence documenting the relationship between perimenopause, menopause, and migraine and diagnostic considerations in an attempt to determine the management of these periods of a woman's life. Special considerations, future directions, and unmet needs for perimenopausal and menopausal migraine are also discussed.

Investigating migraine phenotype and dynamics in women with endometriosis: an observational pilot study

INTRODUCTION

Migraine and endometriosis are chronic disabling pain conditions. There is evidence for a shared genetic background. Migraine phenotype and course in patients with the comorbidity are insufficient investigated. Both conditions can be treated with progestins.

METHODS

For this observational study we included women with migraine and endometriosis, visiting our clinic from 2015 to 2021. We collected available information from charts and complemented these data by a structured phone interview to collect more specific information on migraine and the course of both diseases.

RESULTS

From 344 patients fulfilling the inclusion criteria, 94 suffered from both, endometriosis and migraine. Migraine with aura was reported by 41% of the patients and was associated with earlier onset of migraine (age < 17 years (OR 6.54) and with a history of medication overuse headache (OR 9.9, CI 1.6-59.4). Present monthly migraine frequency (1.5 ± 2.6) was significantly lower than five years before the interview (2.9 ± 4.64). There was a correlation between medication overuse headache and use of analgesics more than 3 days/months for dysmenorrhoea (p < 0.03). ASRM endometriosis score was not associated with migraine characteristics.

CONCLUSIONS

We conclude that the comorbidity of endometriosis is highly linked to migraine with aura. Migraine onset in these patients was earlier. Further studies are needed to explore, if the observed decrease in migraine frequency can be attributed to recent endometriosis surgery and to understand if early diagnosis and treatment of both conditions may contribute to improve the course of both conditions.

Relation and Treatment Approach of Migraine in Pregnancy and Breastfeeding

Headaches are one of the most frequent reasons people visit the neurology department. In 2019, headache issues ranked as the 14th most common cause of disability-adjusted life years globally. According to the International Headache Society, migraine is a particular type of headache that is unilateral, frequently throbbing, associated with vertigo, and sensitive to light, sound, and head movement. A migraine has four stages: premonitory, aura, headache, and postdrome. Migraine is the type of discomfort that most frequently complicates the pregnancy. A migraine is more common in women than in men. Migraines are influenced by increased levels of estrogen during pregnancy and a sharp decrease in those levels during puerperium. Untreated migraine can result in premature labor, hypertension, and low birth weight babies. Menstrual-related events occurred more frequently in migraine sufferers than in non-migraine sufferers. We have explained the relation of sex hormones that trigger migraine. We have also reviewed the therapeutic approach, such as pharmacological and non-pharmacological approaches, for migraine in pregnancy and breastfeeding. A migraine episode during menstruation was slightly more severe and complicated than a headache that wasn't a migraine. Breastfeeding is not prohibited by migraines. The steady estrogen levels brought on by lactating women's lack of menstruation may function as a protective factor. In addition to any required drug therapy, nonpharmacological techniques should always be used as the first line of treatment. Preconception counseling is an essential part of providing headache patients with safe therapy during pregnancy. Supplemental estrogen should not be used by any women who have an aura or who are 35 years of age or older because there is inadequate proof to support any long-term adverse effects. Paracetamol is advised for use in acute therapy during pregnancy. Mothers who used acetaminophen during pregnancy are more likely to have children with hyperkinetic disorders and characteristics resembling attention-deficit/hyperactivity disorder. Menstrual migraine can be treated in a variety of ways, including acute therapy, non-pharmacological therapy, and preconception counseling. Similar tactics are used to treat migraines during pregnancy, but it's important to take the medications' safety rating into account. Migraines and menstrual problems go together. A safeguarding element is a constant estrogen level during pregnancy and breastfeeding. The preferred method of treatment for migraine is non-pharmacological therapy, followed by prenatal counseling. Sumatriptan and acetaminophen are both effective treatments for transient migraine attacks that occur during pregnancy or breastfeeding.
