Hypothesis
What is the course of headaches and migraines during pregnancy and postpartum?
Conclusion
Most women with migraines experience a decrease in headache frequency during pregnancy, but there is an increase in intensity and duration postpartum.
Supporting Evidence
- 208 women with migraine filled in detailed headache diaries during pregnancy.
- Freedom from earlier headaches during pregnancy was significantly more common than new onset of headache.
- There was a gradual decrease in headache frequency during pregnancy.
- Postpartum, there was a significant increase in headache intensity and duration.
Takeaway
Many women who usually get headaches feel better when they are pregnant, but they might have more headaches after the baby is born.
Methodology
The study involved questionnaires and headache diaries filled out by pregnant women to track headache occurrences and characteristics.
Potential Biases
Self-assessment of migraine may lead to underreporting or misclassification of headache types.
Limitations
Two-thirds of participants had incomplete diary entries, which may affect the results.
Participant Demographics
Mean age of participants was 28.4 years, with a mix of nulliparous and multiparous women.
