What is a Silent Migraine with No Headache?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 22nd, 2026.
A silent migraine is a neurological condition where patients experience migraine symptoms without the characteristic head pain. These episodes, also called acephalgic migraines, affect approximately 3-5% of migraine sufferers. Symptoms include visual disturbances like flashing lights or blind spots, dizziness, nausea, sensitivity to light and sound, and confusion. The aura phase typically lasts 20-60 minutes and follows the same neurological pathways as traditional migraines. Silent migraines can be triggered by stress, hormonal changes, certain foods, or sleep disruption. While less debilitating than painful migraines, they still require medical evaluation to rule out other conditions like stroke or seizures.
