Migraine Without the Headache

When most people hear the word migraine, they picture a pounding headache.

But headache isn’t necessarily the main event.

For some people, a migraine can produce dramatic changes in vision, tingling or numbness, difficulty speaking, dizziness or vertigo—and no headache at all.

That can be confusing and, especially when it happens for the first time, frightening.

It can also lead people to wonder whether something much more serious is happening.

Sometimes it is.

That’s why understanding the less familiar ways migraine can appear is useful—particularly as we get older.

A migraine doesn’t always mean head pain

The International Headache Society recognizes a condition called typical aura without headache.

In this form of migraine, a person experiences the neurological symptoms of an aura, but no headache accompanies or follows it within 60 minutes. (ICHD-3)(opens in a new tab)

The symptoms can be surprisingly vivid.

You might see:

• Zigzag lines or shimmering lights
• Flashing or sparkling spots
• Blind spots or areas where vision seems distorted
• Tingling or numbness, sometimes spreading from the hand up the arm and into the face
• Difficulty finding the right word
• Difficulty speaking or understanding language

These symptoms are usually temporary and completely reversible.

A typical migraine aura generally develops gradually, often over several minutes, and individual symptoms usually last between 5 and 60 minutes. (ICHD-3)(opens in a new tab)

Then they disappear.

No pounding headache necessarily follows.

Why does the headache sometimes disappear?

This is particularly interesting for older adults.

Some people who have experienced migraine with aura earlier in life find that, as they get older, the headache component becomes less prominent or disappears while the aura continues.

The American Migraine Foundation notes that migraine aura without headache can occur in people whose previous migraines included headache, and that this pattern can become more common with age. (American Migraine Foundation)(opens in a new tab)

So someone who has had migraines for decades might eventually say:

“I still get the strange visual disturbance—but I don’t get the headache anymore.”

That doesn’t necessarily mean the migraine has gone away.

The manifestation may simply have changed.

The visual experience can be particularly strange

Migraine aura is often visual.

People describe:

• Jagged or zigzag lines
• Flashing lights
• Shimmering edges
• Geometric patterns
• Areas of missing vision
• A sensation that part of the visual field is distorted or obscured

One important detail is that a typical visual aura generally comes from the brain’s visual processing system rather than from a problem in one eye.

It can therefore feel as though one eye is affected even when the visual disturbance is actually present in both eyes. (American Migraine Foundation)(opens in a new tab)

That’s one reason doctors sometimes ask patients to cover one eye and then the other while the symptoms are occurring.

It isn’t always about vision

Aura can affect other parts of the nervous system.

Sensory aura

You might experience tingling or numbness, often beginning in one location and gradually spreading.

For example, it might begin in the fingers, move up the hand and arm, and then affect part of the face.

Speech and language problems

Some people temporarily have difficulty finding words or producing language even though they know what they want to say.

These symptoms can be especially alarming because they can resemble a stroke.

Dizziness and vertigo

Migraine can also be associated with significant vestibular symptoms.

Vestibular migraine involves episodes of moderate or severe vestibular symptoms lasting from 5 minutes to 72 hours. Importantly, the diagnostic criteria do not require a headache during every episode. Instead, migraine features such as light/sound sensitivity or visual aura may accompany some attacks. (ICHD-3)(opens in a new tab)

This is one reason someone with recurrent unexplained dizziness may not immediately recognize migraine as a possibility.

There are other unusual forms

Migraine with brainstem aura, for example, can involve symptoms such as vertigo, ringing in the ears, double vision, difficulty speaking, impaired coordination or a reduced level of consciousness. (ICHD-3)(opens in a new tab)

There is also hemiplegic migraine, a rare form involving temporary motor weakness.

These are not simply different names for the same thing. They are distinct migraine subtypes with specific diagnostic criteria.

And that’s important because symptoms such as weakness, difficulty speaking or sudden visual loss can have causes other than migraine.

Here’s where things get serious

A new neurological symptom should not automatically be called a migraine.

This is especially important for an older person who has never experienced aura before.

A stroke or transient ischemic attack (TIA) can produce symptoms that resemble migraine aura.

The International Headache Society specifically says that when aura occurs for the first time after age 40—or when symptoms are unusually brief, prolonged or exclusively negative—other causes, particularly TIA, should be ruled out. (ICHD-3)(opens in a new tab)

There is a useful general difference in how the symptoms may behave:

Migraine aura often develops gradually and evolves.

A stroke or TIA can produce neurological loss suddenly.

But this distinction isn’t reliable enough to diagnose yourself.

If you’re experiencing new neurological symptoms, particularly sudden weakness, facial drooping, difficulty speaking, severe trouble walking, sudden vision loss or other possible stroke symptoms, seek urgent medical evaluation.

Don’t wait to see whether a headache develops.

One eye or both eyes matters

Here’s another surprisingly important distinction.

Temporary visual changes that are actually occurring in one eye can have causes unrelated to typical migraine aura.

Retinal migraine is extremely rare, and the International Headache Society emphasizes that other causes of transient monocular vision loss need to be excluded. (ICHD-3)(opens in a new tab)

So if you suddenly lose vision in one eye—even temporarily—that deserves medical attention rather than being casually dismissed as a “silent migraine.”

Why diagnosis can be difficult

There is no blood test that simply says:

“This is migraine.”

Migraine is diagnosed primarily from the person’s symptoms, their pattern over time, medical history and examination. Doctors may use imaging or other tests when necessary to exclude other conditions. (American Migraine Foundation)(opens in a new tab)

That makes the patient’s description unusually valuable.

Instead of simply telling a doctor:

“I got dizzy.”

or:

“My vision went funny.”

it can help to describe exactly what happened.

Did it build gradually or happen instantly?

Did the symptoms spread from one part of the body to another?

Did the visual disturbance occur in one eye or both?

How long did it last?

Did you experience tingling, numbness, speech difficulty, nausea, light sensitivity or sound sensitivity?

Have you experienced anything similar before?

Those details can help a healthcare professional distinguish migraine aura from other possibilities.

The International Headache Society even notes that keeping a prospective aura diary can help clarify the diagnosis when the symptoms are difficult to describe. (ICHD-3)(opens in a new tab)

A useful lesson about migraine

Perhaps the most important thing to understand is that migraine is more than a headache.

Head pain is one possible part of a migraine attack—not the definition of every migraine experience.

For some people, the most noticeable symptom may be visual.

For others, it may be sensory.

For others, dizziness or vertigo may dominate.

And for some, the familiar headache simply isn’t there.

That doesn’t mean every episode of dizziness, visual disturbance or numbness is migraine.

Quite the opposite.

Because migraine can imitate other neurological conditions, and other conditions can imitate migraine, new or unusual symptoms deserve proper evaluation.

The useful question isn’t:

“Do I have a headache?”

It is:

“What exactly is happening, how does it develop, how long does it last—and has this pattern been properly evaluated?”

That distinction can be surprisingly important.
