What causes migraine headaches linked to the menstrual cycle?
A small study of 22 women with menstrual migraine found some had unusual levels of immune proteins in their blood. It's unclear whether this causes migraine or what it means for treatment.
What they did
Researchers measured immune proteins in the blood of 22 women who experience headaches linked to their menstrual cycle.
What they found
Of the 22 women studied, 6 had lower than normal immunoglobulin A levels and 5 had higher than normal immunoglobulin M levels. The text also noted that the week after menstruation typically has few or no symptoms, even though progesterone levels are very low during this time, suggesting progesterone deficiency is unlikely to be the cause of PMS.
What it means for you
Some women with menstrual migraine may have differences in immune proteins. However, this was a small study, so results may not apply to all women with this problem. The observation about symptom-free weeks with low progesterone suggests that progesterone deficiency is probably not the main cause of PMS.
