Objective: To examine the prevalence of migraine in women with chronic pelvic pain with and without endometriosis.
Design: Prospective study of headache, pelvic pain, and quality of life before laparoscopic surgery for pelvic pain. Endometriosis was diagnosed pathologically. Headaches were classified as migraine or non-migraine using International Headache Society criteria.
Setting: Clinical research hospital.
Patient(s): 108 women in a clinical trial for chronic pelvic pain (Trial ID NCT00001848).
Intervention(s): Laparoscopy to diagnose endometriosis, assessment by neurologist to assess headaches.
Main Outcome Measure(s): Prevalence of migraine and other headaches in women with chronic pelvic pain with or without endometriosis. Headache frequency, severity and relationship to pelvic pain and endometriosis.
• Lifetime prevalence of definite or possible migraine was 67% of women with chronic pelvic pain.
• An additional 8% met criteria for possible migraine [75% total].
• Migraine was no more likely in women with endometriosis than those without.
• Women with the most severe headaches had a lower quality of life compared with those with pelvic pain alone.
• Migraine headache is common in women with chronic pelvic pain, regardless of endometriosis,
• And contributes to disability in those with both conditions.
• The strong association suggests a common pathophysiology. [bolding added]
