Sex-related differences in epidemiological and clinic-based headache studies.

This manuscript discusses sex-related differences in headache prevalence, the symptoms and natural history of migraine, associated disability, and co-morbid disorders. The role of sex hormones is discussed with reference to the effects of hormonal events across the reproductive years and the specific effects of the menstrual cycle on migraine. Differences between the sexes were identified across all parameters reviewed.

Safety and tolerability of frovatriptan in the acute treatment of migraine and prevention of menstrual migraine: Results of a new analysis of data from five previously published studies.

Background: Triptans are a recommended first-line treatment for moderate to severe migraine.

Objective: Using clinical trial data, we evaluated the safety and tolerability of frovatriptan as acute treatment (AT) and as short-term preventive (STP) therapy for menstrual migraine (MM).

Methods: Data from 2 Phase III AT trials (AT1: randomized, placebo controlled, 1 attack; AT2: 12-months, noncomparative, open label) and 3 Phase IIIb STP trials in MM (MMP1 and MMP2: randomized, placebo controlled, double blind, 3 perimenstrual periods; MMP3: open label, noncomparative, 12 perimenstrual periods) were analyzed.

Migraine headache in perimenopausal and menopausal women.

Perimenopause marks a time of change in a woman's hormonal environment, which is apparent from the resultant irregular periods and vasomotor symptoms. These symptoms can start in the early 40s and continue through to the early 50s. Migraine is also affected by hormonal fluctuations, particularly the natural decline in estrogen in the late luteal phase of the menstrual cycle.

Headache and hormone replacement therapy in the postmenopausal woman.

Headache and migraine are common symptoms of the menopause, often associated with irregular periods, hot flashes, and night sweats. Perimenopausal women should routinely be asked about headache and migraine, so that they can be offered appropriate advice. If attacks are infrequent, it may be sufficient to optimize acute treatment strategies.

Menstrual migraine.

Purpose Of Review: Menstrual migraine is prevalent but it is only recently that research has specifically addressed the pathophysiology and management of this disabling condition.

Recent Findings: For many years, menstrual migraine was a loose term used to describe an undefined association between migraine and menstruation. The introduction of recognized criteria has improved the diagnosis and enabled the study of a more homogenous population of women with this condition.

Incidence of migraine relative to menstrual cycle phases of rising and falling estrogen.

Objective: To investigate the association between urinary hormone levels and migraine, with particular reference to rising and falling levels of estrogen across the menstrual cycle in women with menstrual and menstrually related migraine.

Methods: Women with regular menstrual cycles, who were not using hormonal contraception or treatments and who experienced between one and four migraine attacks per month, one of which regularly occurred on or between days 1 +/- 2 of menstruation, were studied for three cycles. Women used a fertility monitor to identify ovulation, conducting a test each day as requested by the monitor, using a sample of early morning urine.

Migraine and the menopause.

The prevalence of migraine peaks during the 40s and an increased association between migraine and menstruation is often noted. Migraine generally improves after the menopause. Although menstrual irregularity, hot flushes and other climacteric symptoms may warrant management with hormone replacement therapy (HRT), there has been some concern that HRT may aggravate migraine and potentially increase the risk of ischaemic stroke.

Feeling and seeing headaches.

The aim is to deepen our understanding of headache by three approaches. First, by trying to feel patients' total experience by eliciting their symptoms in detail, and from their reactions to these experiences. Second, by trying to remember one's own experience of headache, and observing a few patients during different headache types.

Prevention of migraine in the pill-free interval of combined oral contraceptives: a double-blind, placebo-controlled pilot study using natural oestrogen supplements.

Context: Migraine in the pill-free interval of combined oral contraceptives is reported by many women, but there is little published information on possible mechanisms and treatments.

Objective: To determine whether the use of natural oestrogen patches affected the occurrence and severity of migraine during the pill-free interval.

Design: A double-blind, placebo-controlled, randomised, crossover study.

Female sex hormones and migraine.

During the reproductive years migraine is three times more common in women than in men. Although it is often assumed that this female preponderance is associated with the additional trigger of fluctuating sex hormones of the menstrual cycle, few studies have been undertaken to confirm or refute this. There is increasing evidence confirming an association between estrogen 'withdrawal' and attacks of migraine without aura, as well as evidence for an association between high estrogen states and attacks of migraine with aura.

Predicting menstrual migraine with a home-use fertility monitor.

A home-use fertility monitor was used to time perimenstrual prophylaxis in 27 women with menstrual or menstrually related migraine. Cycle length variability was mostly caused by follicular phase variability; the postovulatory luteal phase was relatively constant. The monitor accurately identified ovulation in >90% of cycles, enabling prediction of menstruation and precise timing of perimenstrual prophylaxis.
