Migraine and hormones are closely linked, which is why perimenopause is often the worst stretch a migraine sufferer has.
It is also a symptom where one specific detail — whether you get aura — changes what a doctor can safely offer you. It comes up surprisingly rarely.
What changes
Existing migraines get worse. More frequent, longer, less predictable. The pattern that held for twenty years stops holding.
Attacks cluster around hormonal drops. Classically premenstrually, though in perimenopause the timing becomes erratic because the cycle does.
New headaches appear. Some women develop migraine for the first time in their forties.
Tension-type headaches increase, often driven by poor sleep, neck and shoulder tension, and clenching.
Then, for many, it improves. Migraine frequently settles after the transition, once fluctuation stops. That is genuinely worth knowing during the bad years.
Why fluctuation matters more than level
Migraine is triggered by hormonal change, particularly falling levels, rather than by any absolute level.
Perimenopause is defined by fluctuation. Levels swing unpredictably, sometimes higher than they ever were, sometimes much lower, often within the same month.
That is why this phase is frequently worse than postmenopause, when things settle.
The aura question
Worth its own section, because it is clinically important and under-discussed.
Aura is a neurological disturbance that comes before or during a migraine. Most often visual — zigzag lines, flashing shapes, a blind spot that expands. Sometimes tingling spreading up an arm, or difficulty finding words. It usually lasts under an hour and resolves.
Why it matters: migraine with aura is associated with a higher stroke risk, and that association affects which options are suitable for you — including some forms of contraception.
So this is a specific thing to tell a doctor, unprompted:
"I get migraine, and I do / do not get aura with it."
If you are not sure, describe what happens before the pain starts and let them determine it.
What helps
Track properly. Date, duration, severity, what preceded it, where you were in your cycle, how you slept. Two months of this is worth more than any description. A clear premenstrual pattern changes what a doctor considers.
Protect sleep. Both too little and disrupted sleep are strong triggers, and perimenopause supplies plenty of both. See sleep problems.
Eat and drink regularly. Skipped meals and dehydration are common, avoidable triggers.
Watch alcohol, red wine especially.
Check your iron. Heavier perimenopausal periods cause iron deficiency, which worsens headaches. Ask for ferritin specifically.
Mind the painkillers. Taking acute headache treatments too frequently can cause medication overuse headache, which then presents as worsening migraine. If you are reaching for something more than a couple of days a week, raise it — this is common and easily missed.
Manage neck and shoulder tension. Contributes more than most people expect, and physiotherapy helps where it is a factor.
What to discuss with a doctor
Bring the diary. State the aura question explicitly. Mention how often you take anything for it, honestly.
Ask what the options are for prevention as well as for treating attacks, and how each applies given your history and whether you have aura.
