Menstrual migraine, encompassing pure menstrual migraine (PMM) and menstrually related migraine (MRM), is common in Norwegian women aged 30-44. The study found PMM prevalence at 2.7% and MRM at 4.6% in this population.
Area of Science:
- Neurology
- Epidemiology
- Women's Health
Background:
- Migraine attacks often increase during the perimenstrual period for many women.
- The International Classification of Headache Disorders (ICHD II) categorizes menstrual migraine into pure menstrual migraine (PMM) and menstrually related migraine (MRM).
- Despite recognition, further evidence is required for formal inclusion in ICHD III.
Purpose of the Study:
- To determine the prevalence of PMM and MRM in the general Norwegian population.
- To investigate the occurrence of self-reported menstrual migraine in women aged 30-44.
Main Methods:
- A postal questionnaire survey was distributed to 15,000 women aged 30-44 in eastern Norway.
- The questionnaire included six questions on migraine, headache frequency, and the relationship between migraine and menstruation.
- A total of 11,123 women completed the survey, yielding a response rate of 77%.
Main Results:
- The prevalence of self-reported migraine was 34.8%.
- Among migraineurs, 21% reported menstrual-related migraine.
- Prevalence rates for PMM and MRM in the general population were 2.7% and 4.6%, respectively.
Conclusions:
- Self-reported menstrual migraine, including PMM and MRM, is prevalent in Norwegian women aged 30-44.
- These findings contribute to the scientific evidence needed for potential inclusion in future headache disorder classifications.
- Menstrual migraine appears to be a common condition affecting a significant portion of women in this age group.

Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.
