Silent migraine—also called migraine aura without headache or acephalgic migraine—is a type of migraine where the neurological and sensory symptoms of aura appear, but the headache never comes. While the name may make it sound mild, many people describe these episodes as unsettling, disruptive, and sometimes disabling.
According to the American Migraine Foundation, a silent migraine includes the same aura phase as a typical migraine: visual changes, sensory disturbances, or speech difficulties. The main difference is the absence of the throbbing headache that many people associate with migraine.
If you’ve ever felt invalidated because your migraine doesn’t come with pain, know that this type is very real and deserves care and recognition.
How Common Is It?
Silent migraine is relatively rare compared to other migraine types. Estimates suggest that about 3–5% of people with migraine experience aura without headache at least sometimes. It also appears more frequently in people over 40 and in those who have lived with migraine for many years.
If you’ve only recently started having these episodes, you’re not alone. Many people develop silent migraine later in life, even after years of more “typical” attacks.
Symptoms of Silent Migraine
The symptoms of silent migraine stem from changes in brain activity during the aura phase. These symptoms usually develop gradually over 5–20 minutes and can last up to an hour. Common experiences include:
-
Visual disturbances: flashing lights, zigzag lines, blind spots, or shimmering effects
-
Sensory changes: tingling or numbness, usually spreading through the hand or face
-
Speech or language difficulties: struggling to find words or speak clearly
-
Balance issues or dizziness: unsteadiness or lightheadedness
-
Other symptoms: nausea, fatigue, or ringing in the ears
These symptoms can be just as disruptive as migraine pain. If you’ve ever felt disoriented by flashing lights or sudden word loss, remember that your brain is processing a real neurological shift—it’s not “just stress” or something you’re imagining.
The Phases of Silent Migraine
Even without the headache, silent migraine often follows the same phases as a typical migraine:
-
Prodrome – Subtle changes hours or days before, such as fatigue or irritability
-
Aura – Neurological symptoms that develop and peak within an hour
-
Skipped Headache Phase – The headache does not appear
-
Postdrome – Lingering tiredness or brain fog
Postdrome can still leave people feeling drained, even if pain never occurred.
If you feel wiped out after a silent migraine, you’re not overreacting—your brain has just been through an event that takes energy to recover from.
What Triggers Silent Migraine?
Triggers for silent migraine are often similar to those of painful migraine. They may include:
-
Stress or sudden relaxation after stress
-
Hormonal changes
-
Skipped meals or dehydration
-
Bright or flickering lights
-
Weather changes
-
Strong smells or loud noises
Patterns vary, so tracking your own symptoms can be key. If your triggers feel unpredictable, don’t blame yourself. Migraine triggers are complex, and identifying even one or two patterns can make management easier.
Why Diagnosis Matters
Because silent migraine lacks a headache, it can look like something else—particularly stroke or transient ischemic attack (TIA). For this reason, doctors may use neurological exams or imaging tests to rule out other causes.
If you ever feel nervous that what you’re experiencing might be something more serious, it’s valid to seek medical care. Silent migraine is a diagnosis that should never come from self-guessing alone.
Treatment and Management
Treatment focuses on prevention and managing symptoms, since aura often passes before medication can take effect.
-
Lifestyle approaches: regular sleep, hydration, balanced meals, and stress reduction
-
Acute medication: NSAIDs or triptans may help, especially if other migraine symptoms occur
-
Preventive treatment: medications like beta-blockers, calcium channel blockers, or CGRP inhibitors may reduce frequency
-
Supportive care: addressing nausea, dizziness, or fatigue when they happen.
Management often requires individualized care since aura-focused treatments are still being studied. If what works for others doesn’t work for you, that doesn’t mean you’re out of options—silent migraine often requires a more tailored approach.
The Impact of a “Silent” Attack
Even without pain, silent migraines can interrupt work, school, and safety, especially if vision, balance, or speech are involved. The word “silent” can be misleading; these episodes are anything but invisible to the person experiencing them.
If you’ve ever felt dismissed because you didn’t have pain, your experience is still valid. Silent migraine is real, and your challenges with it matter.
Key Takeaway
A silent migraine is not a mild migraine—it’s a neurological condition with its own set of challenges. Understanding what it is, learning to recognize triggers, and seeking medical support can make living with it less overwhelming.
You’re not alone in this. Even without head pain, your symptoms are real, and they deserve recognition and care.
