What Is a Menstrual Migraine?

Menstrual migraine refers to migraine attacks that occur in a predictable relationship to menstruation. Some women have attacks only around their period. Others have menstrual-related attacks as well as migraine at other times of the month.

When Does a Menstrual Migraine Occur?

The typical menstrual window begins two days before the start of a period and continues through the first three days of bleeding. A headache and cycle diary kept over several months can show whether attacks repeatedly cluster within that window.

Why Does Estrogen Trigger Migraine?

Estrogen levels fall rapidly just before menstruation. In a brain already susceptible to migraine, that withdrawal can lower the threshold for an attack. This does not mean estrogen is the only trigger; sleep, stress, meals and other factors can interact with the hormonal change. Learn more about hormones and the brain.

What Does a Menstrual Migraine Feel Like?

The symptoms are those of migraine, but menstrual attacks are often longer, more intense and sometimes harder to treat than attacks at other times. They may include throbbing pain, nausea, and sensitivity to light or sound. Aura status should be tracked because it can affect treatment and vascular-risk discussions.

Why Can Migraines Change During Perimenopause?

During perimenopause, hormone fluctuations and menstrual timing become less predictable, so migraine patterns can change too. Once menopause is established and fluctuations become more stable, some women improve, although individual experiences vary.

How Are Menstrual Migraines Treated?

Treatment may include standard acute migraine therapies. For women with predictable attacks, clinicians sometimes consider short-term preventive strategies around the menstrual window. Care should be individualized according to migraine type, aura, other medical conditions, current medications and vascular risk factors. Hormone therapy is not necessary or automatically appropriate for treating menstrual migraine.

When Should You Talk With Your Doctor?

Discuss attacks that are frequent, prolonged, disabling, changing in pattern or not responding to your usual treatment. Bring a headache-and-cycle diary and a medication list. New aura or a major change in neurological symptoms deserves prompt assessment; see the MenoCortex guide to migraine with aura.
