For women, men, and children who suffer from migraine disease, Migraine Heroes is your go-to resource for understanding, managing, and overcoming migraine attacks.

We cover all types of migraines and related headaches, including primary and secondary migraines, chronic migraines, and cluster migraines. We dive deep into the complexities of migraine with aura and migraine without aura, as well as rarer forms like hemiplegic migraine, retinal migraine, and acephalgic migraine (silent migraine). Our discussions also extend to cervicogenic headaches, ice pick headaches, and pressure headaches, which often mimic migraine or contribute to overall migraine burden.

Transcript

[00:00]

Have you ever known exactly what you want to say, yet the word seemed to disappear or

[00:05]

worse change just as you reached for it?

[00:10]

Welcome to Migraine Heroes, a podcast for people living with chronic migraines with

[00:15]

years of pain, misunderstanding and lack of answers.

[00:19]

I'm Diane Ducarme, I've helped more than a thousand people reduce the burden of migraines

[00:24]

and feel more in control.

[00:26]

My mission in life?

[00:28]

To help a million people.

[00:30]

Each episode brings you grounded insight into what your body might be asking for and what

[00:35]

can truly help.

[00:38]

Just to keep you fully supported, this podcast is educational.

[00:42]

For diagnosis or medication, always work with your doctor.

[00:47]

Now take a breath and let's dive in.

[00:51]

In this episode, you will learn why migraine can make familiar words suddenly feel unreachable,

[00:57]

even when you know perfectly well what you want to say, how to distinguish ordinary migraine-related

[01:02]

cognitive slowing from a possible speech or language aura, and when a sudden language

[01:08]

problem requires immediate medical attention.

[01:12]

Stay with me till the end, because by the end of this episode, you will have understanding

[01:16]

and word recovery tools you can begin using during your next migraine attack.

[01:22]

A couple of years ago, I spoke with the first woman who ever described a speech aura to

[01:27]

me.

[01:28]

And at the first time, I did not even know this was possible.

[01:32]

I was still discovering just how many different forms migraine can take.

[01:35]

And I remember her words so clearly.

[01:37]

She said, I'm here, I know exactly what I want to say, but a different word comes out

[01:43]

of my mouth.

[01:45]

And she described it as though she were standing outside of her own body.

[01:48]

Her mind knew what she wanted to communicate, but her body seemed to say something completely

[01:53]

different.

[01:54]

And that conversation stayed with me.

[01:56]

I could see the despair on her face, the confusion, and the fear, the fear that an experience

[02:01]

like this can create.

[02:03]

Because when your own words no longer seem to belong to you, even for a short time, it

[02:08]

can feel deeply frightening.

[02:10]

And what struck with me most was how little understanding she had received.

[02:13]

She did not only need an explanation, she needed someone to tell her, I believe you,

[02:17]

this is real.

[02:18]

And actually, you're not alone.

[02:21]

Losing access to words can be deeply unsettling.

[02:25]

You may be sitting in a meeting, speaking with your partner, talking to a doctor or

[02:29]

trying to explain why you need help.

[02:31]

You know the word, you can almost feel it sitting somewhere inside your mind and on

[02:35]

the tip of your tongue, but it doesn't come forward.

[02:38]

And perhaps you just replace it with another word.

[02:41]

Perhaps your sentence stops halfway.

[02:43]

Perhaps you point to an object because you cannot name it.

[02:46]

Or perhaps you simply become quiet because trying to speak feels like pushing through

[02:50]

thick fog.

[02:52]

And then comes the fear.

[02:53]

What is happening to me?

[02:54]

And am I losing my memory?

[02:56]

Will other people think I'm not intelligent?

[02:58]

Is something seriously wrong with my brain?

[03:00]

And please hear this clearly, struggling to find words during margarine does not mean

[03:04]

that you have suddenly become less intelligent.

[03:06]

It does not mean that your personality is disappearing.

[03:09]

It can reflect a temporary disruption in the brain systems responsible for attention,

[03:14]

processing, memory retrieval, and language.

[03:17]

But there is an important distinction we need to make first.

[03:20]

There are two kinds of experiences.

[03:22]

When people say, I cannot find my words during a migraine, they may be describing one of

[03:26]

two overlapping experiences.

[03:29]

The first is general cognitive slowing, often called margarine brain fog.

[03:33]

And in this situation, you may feel mentally slower, forget what you were about to say,

[03:38]

or struggle to follow a conversation, or need more time to retrieve names, or ordinary words.

[03:45]

And this can happen before the migraine, during the painful phase, or during the exhausted

[03:50]

period after the pain has eased.

[03:53]

And so that's one type.

[03:54]

The second experience is a more specific speech or language aura.

[03:58]

And here, the disturbance may be clearly neurological.

[04:01]

You may be unable to name familiar objects, produce the word you intend, understand a

[04:06]

sentence, you may not be able to read normally, or arrange words correctly.

[04:11]

And the international classification of headache disorders recognizes fully reversible speech

[04:17]

or language symptoms as a possible form of migraine aura.

[04:21]

A typical aura generally develops gradually.

[04:24]

The actual aura is going to last between 5 and 6 minutes for each symptom, and it's going

[04:29]

to resolve completely.

[04:31]

And the word gradually here, it really matters.

[04:34]

You're going to understand why.

[04:36]

Migraine aura often unfolds over several minutes.

[04:40]

Of course, the entire migraine attack is much longer.

[04:43]

But one symptom may slowly build or spread, and another may follow it.

[04:48]

For example, a person may first notice shimmering vision, then tingling in one hand, then later

[04:55]

difficulty speaking.

[04:56]

In contrast, a stroke often produces a deficit that begins suddenly, although real-life representation

[05:04]

can overlap.

[05:05]

So you should never attempt to diagnose a difference by yourself.

[05:08]

When some symptoms are new, they're abrupt, they're severe, they're unusual.

[05:13]

We're going to talk about that again.

[05:15]

So what does the word finding difficulty actually mean?

[05:18]

So the medical term for difficulty retrieving the name of a familiar object or familiar

[05:24]

idea is called anomia or dysnomia.

[05:28]

So imagine looking at a key, you recognize it, you know what it is, you may even be able

[05:33]

to say it's the thing that opens the door, but the word key refuses to arrive.

[05:38]

That is different from a memory being erased.

[05:40]

The knowledge may still be present, but the path we use to retrieve and express the word

[05:45]

is temporarily less efficient.

[05:47]

Some people experience difficulty producing language, others have trouble understanding

[05:52]

it.

[05:53]

Some know what they want to say, but produce the wrong word.

[05:56]

A person might say chair, and they really meant table, or use an invented or a distorted

[06:02]

word.

[06:03]

And these experiences can fall under the broad description of aphasic symptoms, meaning that

[06:08]

some parts of language production or comprehension is temporarily disrupted.

[06:14]

Now visual symptoms are by far the most frequently reported form of migraine aura.

[06:19]

Language symptoms are less common, but they are well documented.

[06:23]

So there was a 2024 study published in the Journal of Headache and Pain, and it detailed

[06:27]

interviews where they conducted interviews with 227 adults diagnosed with migraine with

[06:32]

aura, and speech or language aura was reported by 14% of participants.

[06:37]

Because these participants were recruited largely through a specialist headache center,

[06:42]

that number should not automatically be applied to every person with migraine, but still it

[06:45]

confirms that language symptoms form a meaningful part of the migraine aura spectrum.

[06:51]

Now, you do not need to have migraine aura to experience language and memory difficulties.

[06:56]

In 2015, there was a study in Cephalalgia, and they tested people during untreated migraine

[07:02]

attacks, and again, when they were free from headache.

[07:05]

And during attacks, participants performed worse in several areas, particularly word

[07:09]

reading speed, verbal learning, and verbal recall.

[07:13]

So this helps explain why migraine can make conversation feel difficult, even when you're

[07:18]

not having a formal language aura.

[07:21]

Your brain may be processing information more slowly, attention may be pulled toward pain,

[07:26]

nausea, light sensitivity, sound sensitivity, and the basic task of enduring the attack.

[07:32]

Working memory, so the mental space that allows you to hold and manipulate information, may

[07:36]

have less capacity available.

[07:39]

So what might be happening in the brain?

[07:41]

Well actually, language is not stored in one tiny box in the brain.

[07:46]

Migraine requires several brain networks to collaborate.

[07:49]

You need attention to remain with the conversation, you need memory to retrieve the data, you

[07:54]

need language systems to select the word, you need motor planning systems to organize

[07:59]

the sounds, and you need sensory feedback to monitor what you're saying.

[08:03]

Migraine can temporarily disturb this coordination.

[08:06]

And so for migraine aura, one leading explanation is a phenomenon called cortical spreading

[08:11]

depolarization.

[08:12]

This is a slowly advancing wave of altered electrical activity and chemical balance across

[08:17]

the surface of the brain.

[08:19]

In other words, word-finding difficulty may not come from one single malfunction, it may

[08:24]

emerge because a brain already managing pain and sensory threat has fewer resources available

[08:30]

for rapid, precise language retrieval.

[08:33]

Now let us add another layer.

[08:37]

When you notice you cannot find a word, your nervous system becomes alarmed.

[08:41]

You start monitoring every sentence, you push harder, you silently command yourself, come

[08:46]

on, say it, what's wrong with you?

[08:50]

And that pressure creates another cognitive task.

[08:54]

Instead of using all of your available attention for communication, part of your mind is now

[08:58]

watching, criticizing, and predicting disaster.

[09:02]

This does not mean anxiety causes the migraine symptom, it means that fear can make an already

[09:07]

difficult task feel even more impossible.

[09:10]

The goal is not to win a fight against your brain, the goal is to help your brain complete

[09:15]

the task with less pressure.

[09:17]

Now, a bit of an essential safety message.

[09:20]

Because sudden trouble speaking can also be a warning sign of stroke, this symptom really

[09:26]

deserves respect.

[09:28]

Seek emergency medical help immediately when difficulty speaking or understanding language

[09:33]

is sudden, is new, is unusually severe, or is different from your established migraine

[09:39]

pattern.

[09:40]

Particularly when it appears with facial drooping, with weakness or numbness on one side, loss

[09:45]

of balance, sudden visual change, confusion, or sudden severe, do not wait for the symptom

[09:51]

to pass, and do not assume that this is migraine simply because you have a history of migraine.

[09:57]

For new patterns, sudden onsets, or unusual symptoms, get medical help.

[10:03]

And please feel free to re-listen to that, if you have hesitation, re-listen to the podcast,

[10:08]

just listen to what's the nuance between that brain fog, that speech aura, and this

[10:14]

medical emergency, and you'll start to really understand the nuance, they really matter.

[10:19]

Now let us view this experience from another angle.

[10:22]

Traditional transmissing does not describe word-finding difficulty through electrical

[10:26]

brain networks or cortical waves.

[10:29]

It uses a different language, one of movement, nourishment, communication, and balance.

[10:35]

This is not a replacement for neurological assessment.

[10:38]

It's a symbolic or a clinical framework that helps us ask a different question.

[10:43]

Instead of only asking, why is my brain failing to produce this word?

[10:47]

We might ask, what conditions does my whole system need in order for expression to flow?

[10:53]

In traditional Chinese thought, clear speech is not seen as an isolated medical act.

[10:59]

It reflects the cooperation of awareness, memory, energy, emotional regulation, and

[11:04]

the ability to organize thought into expression.

[11:07]

The heart, for example, is traditionally associated with the shen, the clarity and presence of

[11:14]

the mind.

[11:15]

This does not refer simply to your physical heart muscle.

[11:18]

It describes the quality of being mentally present, of being settled, of being able to

[11:25]

connect inner experience with the outside world.

[11:28]

When the mind is agitated, when it's frightened, when it's exhausted, when it's overwhelmed,

[11:35]

speech then may become scattered or difficult.

[11:39]

Then there's the spleen system, and in this traditional language, it is associated with

[11:43]

thought, with concentration, and the ability to transform experience into something understandable.

[11:48]

And when this system is described as depleted, a person may experience a heaviness, mental

[11:52]

fog, repetitive thinking, fatigue, or difficulty organizing ideas.

[11:57]

Then you have the kidney system, associated with deeper reserves, memory, endurance, and

[12:01]

unconstitutional energy.

[12:02]

And after years of chronic pain, poor sleep, fear, and repeated attacks, a person may feel

[12:08]

that these reserves have been drained.

[12:10]

And then you have the liver system, associated with the smooth movement of energy and emotion.

[12:15]

And when movement becomes constrained, expression can be blocked.

[12:18]

The thought is inside, but it cannot move outward freely.

[12:21]

So again, these are not anatomical claims.

[12:24]

They are a traditional map of a human experience.

[12:27]

And there's something compassionate in this map.

[12:29]

It suggests that when you cannot find a word, the answer is not always in pushing harder.

[12:35]

Sometimes the system needs space, quiet, warmth, nourishment, and permission to slow down.

[12:39]

There's a Chinese saying that can be translated as, when the water is still, the reflection

[12:45]

is clear.

[12:46]

So imagine trying to see your face in a bowl of water, while someone is shaking the bowl.

[12:51]

The harder you stare, the less you see.

[12:54]

During migraine, your internal water may be already disturbed by your pain, by the light,

[12:59]

by the noise, the nausea, the fear, the exhaustion, and the sensory overload.

[13:04]

And demanding immediate verbal precision is like shouting at the water to become still.

[13:09]

So more traditional wisdom would invite a different response.

[13:13]

To settle the bowl.

[13:14]

To reduce the light.

[13:15]

To reduce the noise.

[13:17]

To place your feet on the floor.

[13:18]

To allow your shoulders to fall.

[13:20]

To breathe out slowly.

[13:22]

To stop forcing the word.

[13:24]

And when the demand softens, another route to meaning becomes available.

[13:28]

You may not remember the word refrigerator, but you may see the cold cupboard in the kitchen.

[13:33]

You may not retrieve someone's name, but you can see the person you met at the clinic.

[13:37]

And this is still communication.

[13:38]

The river has not disappeared, it's simply finding a different path around the stone.

[13:43]

Many people with migraine have spent years proving that their symptoms are real.

[13:48]

And we know they are.

[13:49]

You may have learned to hide pain.

[13:52]

You may have continued working.

[13:55]

You may have learned to smile through nausea and produce intelligent answers while your

[13:59]

nervous system is struggling.

[14:01]

And when your words disappear, that carefully maintained appearance of control can feel

[14:06]

threatened.

[14:07]

And from an Eastern philosophical perspective, this is where softness becomes strength.

[14:10]

A rigid branch can snap in a storm, and a flexible branch moves with the wind and returns.

[14:17]

And so during a language disturbance, flexibility might mean using fewer words.

[14:21]

It might mean telling someone that you need silence.

[14:24]

It might mean abandoning the sentence and returning to it later.

[14:28]

It might mean communicating by text, rather than speech.

[14:32]

The Western mind often says, I must get back to normal immediately.

[14:35]

A more balanced response might be my system is moving through something.

[14:39]

I will support it without abandoning safety.

[14:41]

This is not surrender, it's just a skilled cooperation.

[14:45]

So this is hard, and it really is, and it feels, and it can be so scary.

[14:50]

What I'm asking you today is by listening to this podcast, trying to feel, okay, in

[14:55]

what category is my speech problematic?

[14:59]

Is that belonging to brain fog?

[15:01]

Is that belonging to migraine aura?

[15:05]

Was that belonging to something that requires more urgent medical care?

[15:10]

And then once you know, how can I cope?

[15:13]

How can I bring softness in my life?

[15:16]

How can I regain control?

[15:18]

How can I find myself again?

[15:19]

This is a hard one, and remember, every small step you take moves you closer to freedom.

[15:26]

You are powerful, you are resilient, and you're not alone.

[15:31]
