Migraine can become more frequent during perimenopause as estrogen levels fluctuate. The Menopause Society notes that some women improve after menopause, while others continue to have migraine.[1]
Hormones are one part of the pattern
A history of migraine around menstrual periods can make a hormonal connection more plausible. During perimenopause, less predictable cycles can make that pattern harder to recognize.[1]
Other influences may overlap. MedlinePlus lists sleep changes, stress, skipped meals, caffeine or caffeine withdrawal, and medication overuse among possible migraine triggers. A worsening pattern may involve several of these at once.[2]
What a headache history helps distinguish
Migraine assessment includes the symptoms, medical history and a physical and neurological examination. The description matters: whether the pain pulses, whether activity worsens it, and whether nausea or sensitivity to light or sound accompanies it. Aura can involve visual or other neurological symptoms and may occur before or during an attack.[2]
Dates and descriptions of attacks can be compared with menstrual timing, sleep changes and medicines used. Hormone levels fluctuate during the transition, so the headache history provides context a single measurement cannot.[2][3]
A changed pattern deserves reassessment
A migraine evaluation also considers whether another condition could explain the symptoms. Depending on the findings, additional testing may be needed; the presence of perimenopause does not establish the cause of every new headache.[2]
The practical question is therefore specific: has an established migraine pattern become more frequent, have its features changed, or is this a new type of headache? That distinction helps direct the assessment and keeps the hormonal explanation tied to the actual history.
