Menstrual migraine: diagnosis and treatment

Menstrual migraine: case studies of women with estrogen-related headaches

This paper presents 2 case scenarios that illustrate the complexity of diagnosing and managing migraine associated with hormonal changes. Migraine is commonly associated with comorbidies such as depression, anxiety, obesity, cardiovascular disease, as well as other conditions, thereby making management more challenging for the physician and the patient. The first case is a 35-year-old woman who has migraine almost exclusively during menstruation. She is under a physician's care for long-term management of premenstrual dysphoric disorder (PMDD). Achieving a differential diagnosis of pure menstrual migraine is illustrated, and a detailed treatment plan including use of a migraine miniprophylaxis protocol, management of her PMDD, and prescription of acute treatment medications is reviewed. The second case scenario describes the diagnosis of menstrually associated migraine in a woman who suffers from a frequent disabling migraine along with work-related anxiety and depression. This paper reviews her differential diagnosis, laboratory testing, treatment plan, including management of her comorbid anxiety and depressive symptoms.

The effects of an oestrogen-free, desogestrel-containing oral contraceptive in women with cyclical symptoms: results from two studies on oestrogen-related symptoms and dysmenorrhoea

OBJECTIVES

To evaluate the effects of an oestrogen-free oral contraceptive (Cerazette; 75 mcg/day desogestrel) in women with oestrogen-related symptoms during previous combined oral contraceptive (COC) use (ERS study) and in women with dysmenorrhoea (DYS study).

METHODS

Two similarly designed prospective, non-comparative multicentre observational studies were carried out in Germany. Altogether, 403 women with oestrogen-related symptoms during previous COC use and 406 women with dysmenorrhoea took Cerazette continuously. Symptom-related assessments were made at baseline and after 3-4 months, along with bleeding pattern and treatment satisfaction.

RESULTS

In the ERS study, the four oestrogen-related symptoms studied resolved or improved in over 70% of women. Nausea improved/resolved most (92% of women), followed by breast tenderness (90%), oestrogen-related headache (84%) and oedema (74%). In the DYS study, dysmenorrhoea resolved or considerably improved in 93% of the study population. Correspondingly, use of analgesics dropped from 70% of women at baseline to 8% at study end. Adverse events were reported by 7-8% of both study populations and were mainly bleeding irregularities. Most women in both studies were satisfied with treatment (approximately 90%) and wished to continue treatment after study completion (approximately 85%).

CONCLUSIONS

Cerazette in this study set-up improved oestrogen-related symptoms and dysmenorrhoea in women affected and treatment was well accepted.

Recognition and treatment of menstrual migraine

BACKGROUND

Menstrual migraine is a chronic disorder affecting approximately 12.6 million women in the United States. In spite of its widespread prevalence, menstrual migraine often goes undiagnosed.

REVIEW SUMMARY

Characteristics of menstrual migraine, which include functional disability, increased headache severity, and lack of aura, are often overlooked, and therefore menstrual migraine is often underdiagnosed. Use of a 3-month diary to record migraine patterns can reveal the predictable patterns associated with menstrual migraine, and a diary is demonstrated to be a useful tool in diagnosis. Optimal treatment of menstrual migraine takes advantage of the predictability of the disorder. Treatment alternatives for menstrual migraine include acute therapy and short- or long-term preventive therapies. Acute therapy is given shortly after the migraine begins. Short-term preventive therapies are effective when administered during the time that menstrual migraine is most likely to occur; the treatment window is typically 2 days prior up to 3 days after the onset of menstruation. Providing triptans, nonsteroidal anti-inflammatory drugs, or estrogen supplements (gel or patches) during this window has been demonstrated to provide effective protection during the days when patients are at greatest risk for menstrual migraine. Alternatively, long-term preventive therapy may be required for recurrent headaches in patients with concomitant medical conditions for whom migraine therapy could serve a dual purpose.

CONCLUSION

By recognizing the patterns associated with menstrual migraine, prompt, acute, or preventive therapy can be used to effectively manage the disorder and reduce its related disability.

The use of triptans in the management of menstrual migraine

Many women experience headaches, including migraine, in association with their menstrual cycles. Although definitions vary, menstrual migraine generally refers to migraine without aura that occurs within several days prior to and several days after the onset of menses. Although menstrual migraine has been reported to be more difficult to treat than other types of migraines, there is no evidence from controlled clinical trials to support this assertion. Thus, the pharmacological treatment of menstrual migraine should be similar to that of other types of migraines, except with respect to the use of hormonal manipulations to treat menstrual migraine. Serotonin 5-HT(1B/1D) receptor agonists (triptans) are effective for the acute treatment of both menstrual and non-menstrual migraines. When used as acute therapy, a triptan should be administered early, when the headache is still mild in severity. Ideally, an acute therapy will provide rapid and complete pain relief with no disability. Some patients may require preventive therapy for menstrual migraine based on suboptimal response to an adequate trial of acute therapy. Patient diaries that record headache onset, relationship to the menstrual cycle and treatment response through three complete cycles will allow accurate prediction of the onset of menstrual migraine; this information is also needed to make decisions about timing of intermittent preventive therapy. The goals of intermittent preventive therapy are to reduce the frequency, duration and intensity of menstrual migraine attacks. Clinical studies show that triptans are effective when used as either acute therapy or as intermittent preventive therapy for menstrual migraine. Sumatriptan and zolmitriptan have been evaluated in prospective, randomised, controlled trials for acute treatment. Retrospective analyses and open-label studies also support the use of other triptans as acute therapy. In addition, sumatriptan, frovatriptan, naratriptan and zolmitriptan have been evaluated as intermittent preventive therapy in prospective studies. Thus, data from clinical studies indicate that triptans are effective for the treatment of menstrual migraine.

Menstrual migraine in a representative Dutch population sample: prevalence, disability and treatment

We assessed the prevalence of menstrual migraine and its restrictions on daily activities in a representative Dutch population sample of 1181 Dutch women, aged 13-55 years. Further, we evaluated the potential role of oral contraceptives, and how menstrual migraine is treated. More than half suffered from menstrual complaints, a substantial proportion reported headache or migraine as a frequent problem. Use of oral contraceptives seemed to reduce the occurrence of menstrual complaints, but not the occurrence of headache and migraine. In our study, the prevalence of menstrual migraine (3%) is lower than in the literature, most probably because we did not use a selected group of patients but a population-based sample of ordinary women. It was confirmed that attacks of menstrual migraine are more severe, of longer duration, and more resistant to treatment than migraine attacks at other times of the month.

Hormonal interventions for menstrual migraines

Menstrual migraines are a treatment challenge for both the migraineur and the health care professional. Although some women with menstrual migraines may respond to acute and preventive therapies for nonmenstrual migraines, others continue to suffer from refractory menstrual migraines. These women may respond to hormonal interventions, which may reduce the frequency of menstrual migraines, thereby lessening the need for abortive migraine therapies, decreasing migraine-related disability, and improving quality of life. Menstrual migraines have a distinct pathophysiology that differs from menstrual-related migraines. Published studies have shed light on the effectiveness of a variety of hormonal interventions, including oral contraceptives, which may be administered with an extended-dosing strategy; estrogen replacement therapy; selective estrogen receptor modifiers; danazol; and leuprolide.
