What if the migraine pain never comes?
[00:03]
Welcome to Migraine Heroes, a podcast for anyone living with migraine and wondering
[00:08]
why nothing has fully worked yet.
[00:11]
I'm Diane Ducarme.
[00:12]
Over the past 7 years, I've helped hundreds of people living with migraine.
[00:17]
What I've learned?
[00:18]
No two migraine stories are exactly the same, and none of them are simple.
[00:23]
That is why, in this podcast, we explore migraine from many different angles.
[00:27]
Food, hormones, stress, sleep, the nervous system, emotions, and much more, through the
[00:34]
lens of both modern science and traditional Chinese medicine.
[00:38]
A quick note before we start.
[00:40]
What we talk about here is educational.
[00:43]
For anything related to diagnosis or medication, please keep working with your doctor.
[00:48]
Now take a breath, and let's dive in.
[00:52]
In this episode, you will learn how a migraine can produce very real neurological symptoms,
[00:57]
even when there is absolutely no headache, and what scientists believe is happening inside
[01:02]
the brain when that occurs.
[01:05]
How to recognize the characteristic rhythm of migraine aura, while also understanding
[01:09]
the warning signs that mean you should never simply assume, oh, this is my migraine.
[01:15]
And how traditional Chinese medicine interprets a nervous system that suddenly produces visual,
[01:21]
sensory, or language disturbances, and what that perspective might teach us about regulation,
[01:26]
rhythm, and the conditions surrounding an attack.
[01:30]
Stay with me till the end, because at the end of this episode, you will have a simple
[01:34]
way to observe your next episode more clearly, what happened, how it developed, how long
[01:40]
it lasted, and what is happening in your body before it began.
[01:45]
Okay, so imagine you're sitting at your computer, and suddenly noticing a tiny, tiny shimmering
[01:53]
patch in your vision, and you blink, still there, and then it starts to expand.
[02:00]
And perhaps it turns into a zigzag, a flashing line, or something that looks almost like
[02:07]
broken glass, or a kaleidoscope, and maybe part of the screen seems to disappear, maybe
[02:13]
there's a blind spot, a missing area in your vision, and everything suddenly looks strangely
[02:19]
pixelated.
[02:20]
You may find yourself rubbing your eyes, blinking again and again, and thinking, why can't I
[02:25]
see properly?
[02:27]
And then, perhaps, something else happens.
[02:30]
Your fingers start tingling, the sensation moves slowly into your head, or up your arm,
[02:37]
or for a few minutes, you know exactly what you want to see, but simply you can't find
[02:42]
the right word.
[02:43]
Literally, maybe another word comes out.
[02:45]
And naturally, you wonder, what on earth is happening?
[02:49]
And so you may even think, is this my eye?
[02:51]
Is there something wrong with my vision?
[02:54]
And then some of you might even think, am I having a stroke?
[02:56]
So you're going to make an appointment with a doctor, it might be an optometrist, an ophthalmologist,
[03:01]
and they're going to examine your eyes, and tell you that everything looks normal.
[03:06]
And you're really thinking to yourself, oh my god, you know, my vision, clearly not fine,
[03:09]
what do you mean that my vision is completely normal?
[03:13]
And then someone might say, you may have had a migraine.
[03:18]
And your immediate response might be, hey, a migraine?
[03:20]
That can't be, I had no headache, there was just no headache.
[03:23]
And if someone connects the dots for you, you may eventually hear the words, migraine
[03:28]
aura without headache, what many people call a silent migraine.
[03:34]
And suddenly, this very strange experience starts to have a name.
[03:39]
So what exactly is a silent migraine?
[03:41]
So a silent migraine is a popular term, rather than the preferred medical term.
[03:46]
What people usually mean by it is a migraine aura without headache.
[03:51]
And the International Classification of Headache Disorders, the third edition, recognizes a
[03:56]
condition called typical aura without headache.
[03:59]
Now, in this condition, a person develops the neurological symptoms characteristic of
[04:04]
a typical migraine aura, but no headache accompanies the aura or follows it within
[04:10]
the next hour.
[04:11]
And look, I really want to acknowledge the words typical here, as nothing feels quite
[04:15]
typical in that quite scary experience.
[04:18]
But it tells us something very important, migraine, is that migraine is not simply a
[04:23]
headache disorder.
[04:24]
That's a misconception a lot of people have.
[04:26]
If you do have migraine with pain for years and decades, you know this is far from being
[04:32]
the case.
[04:33]
But if you have silent migraine, this is probably a whole new territory for you.
[04:38]
So head pain is actually one possible expression of a much broader neurological process.
[04:43]
The brain can enter part of the migraine process without necessarily proceeding into the pain
[04:47]
phase.
[04:48]
And that is why somebody can experience a very unmistakable migraine phenomenon while
[04:53]
their head does not hurt at all.
[04:55]
So I want to talk a little bit about what an aura actually feels like, so that you're
[05:01]
certain, right?
[05:02]
If you're at home, you're certain this is what I've been experiencing.
[05:05]
Aura is going to consist of temporary and fully reversible neurological symptoms.
[05:11]
So for typical aura, these most often are going to involve vision, sensation, or language.
[05:16]
And visual symptoms are by far the most common.
[05:19]
So you may see flashing lights, that's a sign, or shimmering lights.
[05:23]
You may see zigzag, sparkling areas, blind spots, or parts of your vision that simply
[05:29]
seems to disappear.
[05:31]
People often describe it in much more everyday language, like looking through a broken glass,
[05:36]
or like a kaleidoscope, a TV static, or heatwaves on a road, or a glitch on a screen, or like
[05:43]
someone erased part of the picture, the picture you're seeing.
[05:47]
And so some describe a flashing crescent, or a jagged line that slowly grows and spreads
[05:53]
across the vision.
[05:54]
So you see many different forms of expression.
[05:57]
And there was a systematic review published in the Journal of Headache and Pain in 2025.
[06:02]
It found that visual disturbances dominate the clinical picture of migraine aura.
[06:06]
So sensory symptoms and language disturbances can occur as well, but in a much smaller proportion.
[06:12]
Now sensory aura itself may feel like pins and needles, or sort of tingling that begins
[06:18]
in one place and then gradually travels.
[06:21]
And a classic example is tingling beginning in the fingers and spreading through the hands
[06:25]
and arm, and sometimes reaching the face.
[06:28]
Language aura can involve difficulty finding words, producing language, or understanding
[06:33]
language normally.
[06:34]
One particularly useful study was published in Cephalalgia in 2016, and patients recorded
[06:40]
their auras prospectively in diaries.
[06:42]
And visual symptoms occurred in 97% of the recorded auras.
[06:47]
Sensory symptoms occurred in approximately a third, while language symptoms were much
[06:51]
less common.
[06:52]
The median duration was around 30 minutes for visual symptoms, and 20 minutes for sensory
[06:56]
or language symptoms.
[06:57]
But biology does not always read the textbook, as we all know, right?
[07:02]
Some auras are shorter, some are longer, and some involve symptoms appearing one after
[07:07]
another.
[07:08]
Now why does it often spread so gradually?
[07:12]
That's one of the most fascinating parts of migraine biology.
[07:15]
The leading explanation for migraine aura involves something called, and we're going
[07:18]
to talk a lot about that concept so you can really keep it in your mind, what is called
[07:23]
cortical spreading depolarization.
[07:26]
So imagine millions of brain cells maintaining delicate electrical and chemical gradients.
[07:31]
And during cortical spreading depolarization, a slowly advancing wave of intense cellular
[07:37]
depolarization travels across parts of your cerebral cortex.
[07:42]
So behind that wave comes a temporary suppression of normal electrical activity.
[07:48]
So the phenomenon moves slowly across the surface of your cortex, and because different
[07:53]
areas of the cortex perform different jobs.
[07:55]
So this may explain one of migraine aura's most characteristic features, is that it evolves.
[08:02]
Something appears, it moves, it expands.
[08:05]
One symptom may give way to another, and then eventually the brain's normal function returns.
[08:10]
That gradual progression is often quite different from the classic description of a vascular
[08:15]
event in which neurological function is suddenly lost all at once.
[08:19]
Very different.
[08:20]
But there's an extremely important qualification here.
[08:22]
You cannot safely diagnose the cause of a new neurological symptom based solely on whether
[08:28]
it appeared gradually or suddenly.
[08:30]
So stroke, transient ischemic attack, seizure, retinal disease, and other neurological disorders
[08:35]
can sometimes resemble migraine aura, while migraine aura can occasionally behave in atypical
[08:41]
ways.
[08:42]
And we're going to talk about that later.
[08:43]
So why is there no headache?
[08:45]
And so now we arrive to that strange part.
[08:47]
And so if the migraine process has begun, why does your head not hurt?
[08:52]
And look, we work with people who massively suffer from migraine and are bedridden because
[08:58]
of pain every single day.
[08:59]
So don't get me wrong, you know, you don't wish it comes with pain in addition, right?
[09:04]
But it's important to understand why.
[09:06]
The most accurate answer so far is science does not completely know.
[09:11]
So the neurological events that are responsible for aura and the biological process responsible
[09:16]
for migraine, head pain, they overlap, but they're not identical.
[09:20]
So migraine pain is going to involve activation of networks that include the trigeminal sensory
[09:26]
system and the structures around the brain, chemical messengers and pain processing pathways
[09:31]
that become involved.
[09:32]
The cortical spreading depolarization can influence these systems and laboratory evidence
[09:39]
suggests pathways through which it could help initiate pain.
[09:43]
But aura does not inevitably produce a headache.
[09:46]
In fact, the existence of migraine aura without headache is powerful evidence that the aura
[09:51]
mechanism and the pain mechanism can be separated.
[09:54]
There was a 2025 scientific discussion by researchers that examined the relationship
[09:58]
between aura and migraine headache and emphasized precisely this point.
[10:02]
Although spreading depolarization is strongly linked to aura, the clinical relationship
[10:08]
between aura and subsequent head pain is considerably more complicated than a simple
[10:13]
aura causes headache.
[10:14]
Think of it less like one domino knocking down the next one and more several interconnected
[10:20]
neurological systems whose activity frequently overlaps, but does not always do so.
[10:26]
And so your brain may generate the aura and the pain network may simply never cross the
[10:31]
threshold required to produce the headache.
[10:33]
It does not make the episode imaginary, not at all.
[10:36]
It does not make it less migraine and simply means pain was not the final expression of
[10:42]
that particular attack.
[10:43]
Because we also serve people who have migraine aura without headache and migraine aura with
[10:51]
headache, so different types of attack for a single person, that's also possible.
[10:55]
And migraine itself, it may begin before the aura.
[10:58]
So another misconception is that the migraine begins the instant you see flashing lights,
[11:02]
right?
[11:03]
Modern migraine research suggests that the story can begin earlier.
[11:06]
So some people experience changes in fatigue, in concentration, mood, appetite, neck sensation,
[11:11]
light sensitivity, sound sensitivity, or yawning before the more obvious part of the attack
[11:16]
begins.
[11:16]
And so research published in the Journal of Headache and Pain in 2023 reviewed brain imaging
[11:21]
evidence suggesting that migraine involves changing activity across the brain system
[11:25]
even before the conventional headache phase.
[11:28]
So it gives us a much richer way to understand migraine.
[11:31]
So instead of saying migraine equals headache, you think migraine is a changing brain state.
[11:37]
Headache can be one part of that state.
[11:40]
Aura can be another.
[11:41]
And occasionally aura occurs without the pain phase at all.
[11:45]
So is silent migraine dangerous?
[11:47]
And a typical migraine aura itself is generally reversible.
[11:51]
But, but, and this is something I often tell people, you cannot always predict when an
[11:56]
aura is going to happen.
[11:57]
You cannot choose the moment.
[11:59]
It may happen while you're sitting safely at home, but it could also happen while you're
[12:03]
driving, crossing a busy street, cooking, or taking care of your children.
[12:07]
And that is important because the danger is not necessarily the aura itself.
[12:10]
The danger can come from what you're doing when the aura begins.
[12:14]
Imagine you're driving your children somewhere and suddenly a blind spot appears.
[12:17]
Part of the road seems to disappear from your vision.
[12:20]
You see shimmering zigzags, flashing lights, or that strange kaleidoscope effect spreading
[12:24]
across your visual field.
[12:25]
Even if you know that the episode will probably pass, your ability to drive safely may be
[12:30]
impaired in that specific moment, right?
[12:33]
Then someone else is driving on the road and someone else is maybe making mistakes with
[12:36]
their phone.
[12:37]
So when we say there is no headache, so perhaps it's not a big problem, I really want to
[12:41]
challenge that idea.
[12:42]
So no pain does not mean no impact.
[12:45]
A silent migraine can still interfere with your vision, with your sensation, with your
[12:48]
speech, and ultimately your ability to safely perform whatever activity you happen to be
[12:53]
doing when it arrives.
[12:54]
And because you cannot simply schedule an aura, recurring episodes deserve to be addressed,
[12:59]
particularly if they affect activities where suddenly losing part of your vision could
[13:02]
put somebody else or yourself at risk.
[13:05]
But this is also where responsible migraine education matters enormously.
[13:10]
A neurological symptom should not automatically be labeled migraine simply because you have
[13:15]
migraine.
[13:15]
So the International Headache Society specifically points out that diagnosing aura without headache
[13:21]
can be more difficult because there is no accompanying headache to help identify the
[13:26]
migraine pattern.
[13:27]
Other conditions, so particularly transient ischemic attack, sometimes need to be excluded.
[13:32]
So this becomes especially important when the experience is new, if it's new for you,
[13:36]
if it's different from your normal pattern, if it's unusually abrupt, unusually prolonged
[13:40]
or persistent.
[13:41]
And if you experience sudden weakness or facial drooping, inability to speak normally, persistent
[13:47]
loss of vision, severe imbalance, confusion or loss of consciousness or another new neurological
[13:53]
deficit, it's important, really, really important to seek a proper medical assessment and not
[13:58]
assume necessarily it is a migraine.
[14:01]
So the same applies when an aura-like phenomenon appears for the first time later in life or
[14:07]
when it changes substantially from a long-established pattern.
[14:10]
And again, the idea is always to reassure oneself, always to know what is happening,
[14:15]
both from a diagnosis perspective and then what to do in order to prevent them that comes
[14:20]
later, that comes next.
[14:22]
There was a 2024 study published in Headache, the journal of head and face pain, and it
[14:27]
examined people with migraine with aura who also experienced ischemic stroke and they
[14:31]
found that new or changed neurological symptoms were important warning clues.
[14:36]
Now let me help you a bit further, how to distinguish the patterns.
[14:40]
So there's no single blood test that says, yes, this was migraine aura.
[14:44]
Much of the diagnosis is going to come from the story of the event.
[14:49]
What happened first?
[14:50]
Was the symptom positive, such as seeing flashing lights or feeling tingling?
[14:55]
Or was something simply lost, such as a vision or sensation?
[14:59]
Did the symptoms spread?
[15:01]
And if it spread, how quickly?
[15:03]
Did one symptom follow another?
[15:05]
How long did each symptom last?
[15:06]
Was everything completely reversible?
[15:08]
And has the same pattern happened before?
[15:11]
And so research is going to demonstrate why detailed timing can be so useful.
[15:16]
Our symptoms have characteristic patterns, but also considerable variability, which means
[15:21]
that careful observation is far more helpful than simply remembering, oh, something really
[15:26]
weird happened in my vision.
[15:27]
So that's why keeping a diary can be so, so helpful.
[15:30]
There's also another reason an aura may last 20 or 30 minutes, but during those 20 minutes,
[15:37]
you're frightened.
[15:38]
Your perception is changing and therefore your perception of time changes.
[15:42]
And after remembering exactly whether something took two minutes, 10 minutes or 40 minutes
[15:47]
can be remarkably difficult.
[15:48]
So writing down creates a much clearer neurological history.
[15:52]
And so this is something you get completely free on the Migraine Heroes app.
[15:56]
So the Migraine Heroes app is that app with the green background and the head with the
[15:59]
love heart inside.
[16:01]
Just by doing your daily check-in, what's called the daily check-in, the app is going
[16:04]
to build the report for you.
[16:06]
So in the app, you can explore it as a dynamic dashboard with graphs, adjusting the time
[16:10]
periods to see what you want.
[16:12]
And when you're ready to bring it to your doctor, you can download it as a PDF and it
[16:17]
laid out clearly with your pain pattern, with your medication, other symptoms and your cycle
[16:21]
dates along them.
[16:22]
If that's something you want to track or that is important for you to track, it's easy
[16:26]
to print or send and easy for your doctor to read through.
[16:29]
Now, what about treatment?
[16:31]
And so this is an area where science still has significant gaps because the aura often
[16:35]
resolves before an oral medication would have time to take effect.
[16:39]
And so treating an isolated aura in the moment, it can be just challenging.
[16:43]
And so Migraine Aura Without Headache was reviewed in Current Pain and Headache Reports
[16:47]
in 2018.
[16:49]
The shortage of clinical trials specifically targeting people who experience aura without
[16:52]
headache was noted.
[16:53]
And then again, in 2025, there was a systematic review and reached just a similar conclusion.
[16:59]
So compared with the enormous amount of research devoted to migraine headache, there is still
[17:03]
limited evidence for therapies specifically targeting aura itself.
[17:07]
Now, it's a nice segue into the East as it may give us more information about all of
[17:13]
that.
[17:14]
So I want to change language completely, not from English to Chinese, but from the language
[17:19]
of neurons, electrical gradients, corticals, spreading depolarization and ion channels
[17:25]
to another language, one that has been used for thousands of years to ask a very practical
[17:29]
question.
[17:30]
If this keeps happening to someone, what can we actually do to make it happen less?
[17:35]
Okay, very basic question.
[17:36]
So imagine you back then, it's 1000 or 2000 years ago, and there's just no MRI, no magnetic
[17:44]
resonance.
[17:44]
Imagine there is no neurologist, there is no migraine medication, there's no pharmaceutical
[17:50]
laboratory waiting for you.
[17:52]
And yet the problem is still there and still needs to be managed.
[17:57]
So this is where I think Eastern medicine becomes incredibly interesting because traditional
[18:01]
Chinese medicine had to develop an entire system of observation and intervention.
[18:05]
And so one of the first things traditional Chinese medicine would notice about the aura
[18:09]
is quite obvious, it's like the eyes are involved.
[18:11]
And when they say the eyes, they always pair the eyes and the vision.
[18:15]
And in traditional Chinese medicine, the eyes and the vision have a particularly strong
[18:21]
relationship with what is called the liver system.
[18:23]
They call it gan in Chinese.
[18:25]
And so classical Chinese medical texts describe the liver having a close functional relationship
[18:31]
with the eyes and the vision.
[18:33]
And now when I say liver, I need to be really clear here.
[18:36]
Traditional Chinese medicine is not necessarily saying that your anatomical liver is diseased
[18:41]
because you see a zigzag.
[18:43]
That's not what it means.
[18:44]
The traditional liver system is a much broader concept.
[18:47]
So in traditional Chinese medicine, the liver system, so gan, when they say that one word,
[18:52]
that one character, is going to include your anatomical liver and your anatomical gallbladder.
[19:00]
But it's going to extend its functions to blood, tendons, ligaments, eyes, nails, menstrual
[19:07]
and reproductive system, and areas traversed by the liver and gallbladder channels, such
[19:12]
as your pelvis, your ribs, your temples, and the top of your head.
[19:16]
And I find those connections absolutely fascinating and absolutely useful and absolutely
[19:22]
actionable because it means you can observe all of that circuit.
[19:26]
That's what we do.
[19:27]
So when you download the Migraine Heroes app, so the green one with the yellow love heart
[19:33]
in the brain, it's going to ask you a set of questions.
[19:35]
And those questions are to understand, okay, among all of your systems, which system needs
[19:41]
the most support?
[19:42]
And what is your primary pattern?
[19:44]
Where to start the work to remove the problem?
[19:46]
And yeah, to remove, to manage, to mitigate the problem.
[19:50]
And so even outside Chinese medicine, human beings have always looked at the eyes as clues
[19:55]
to what's happening inside the body.
[19:56]
So if you notice your friend has their eyes red, injected with blood, or if you notice
[20:01]
your other friend has their eyes, the white of their eyes, really yellow, or when you
[20:06]
notice someone's really exhausted, the eyes look just, you know, really dark and tired
[20:10]
or puffy.
[20:11]
Intuitively, you understand that the eyes reflect what's happening elsewhere in the
[20:17]
body.
[20:17]
And now you need to imagine people doing that for thousands of years, over millions and
[20:21]
billions of people.
[20:21]
And so traditional Chinese medicine is going to take that observation so much further.
[20:26]
When the visual symptoms appear, they ask, is the liver system adequately nourished?
[20:32]
Is there too much upward movement?
[20:34]
Is there tension?
[20:36]
Is there heat?
[20:37]
So heat is a proxy for inflammation.
[20:39]
Is there wind?
[20:40]
Wind is a proxy for too much internal movement in the wrong direction.
[20:44]
Is there insufficient blood or yin to anchor the system?
[20:48]
And suddenly the question is no longer simply, what do I do when the flashing lights arrive?
[20:52]
But it becomes, what conditions are making my system more likely to produce them?
[20:57]
And so that's a much more actionable question.
[21:01]
Now let's pause here for a moment, because I'd like you to check in with yourself.
[21:06]
Just answer quietly in your head.
[21:09]
In the days leading up to an episode, do your eyes feel dry, tired, or strained?
[21:16]
Do your episodes tend to show up after short nights, or after a stretch of stress?
[21:23]
And around an episode, would you say you feel more tense and irritable,
[21:28]
or more depleted with very little energy left?
[21:32]
Now two people can see exactly the same zigzag and need very different things.
[21:37]
For some, the work is releasing that tension and upward pressure.
[21:41]
For others, it's about nourishing and restoring the systems well before the next aura arrives.
[21:47]
Now what you've just noticed are clues to your margarine pattern,
[21:51]
and that's what the Margarine Hero's Method is built around.
[21:54]
We look at your margarine in the way a practitioner would.
[21:57]
Where do you feel it?
[21:58]
What comes with it?
[22:00]
What's going around it?
[22:01]
And how do you feel during it?
[22:03]
And in the app, it only takes a few steps before you get a first look at your own pattern.
[22:08]
It won't replace your doctor for anything new or unusual,
[22:12]
but it might help you find those missing pieces of your margarine puzzle.
[22:17]
And so that's why I love the West and the East,
[22:20]
because you see most of the time they really don't contradict each other.
[22:23]
But at the end of the day, we need pragmatism.
[22:26]
You know, we need to get to destination.
[22:28]
We need to get people better.
[22:29]
And so at the end of the day, we need to have people feel a lot better.
[22:32]
And that can't come from knowledge alone.
[22:34]
So this brings us to another central idea, which is an idea of nourishment.
[22:39]
And so in traditional Chinese medicine, blood means more than blood measured in a lab.
[22:45]
Blood represents nourishment and the body's capacity to support and anchor tissues and functions.
[22:51]
And then there's yin.
[22:52]
And you can think of yin very broadly as the cooling, the nourishing,
[22:56]
the restorative side of physiology.
[22:58]
And traditional Chinese medicine might say,
[23:00]
this person is consuming more than they're restoring.
[23:03]
There's just not enough nourishment, not enough recovery, not enough yin,
[23:06]
not enough blood supporting the system.
[23:09]
And when that foundation becomes weaker, the system may become easier to disturb.
[23:13]
And so that immediately gives us things to work on,
[23:16]
not after the aura, but before the aura.
[23:20]
And so these are really useful concepts.
[23:22]
I remember, you know, starting my lessons of traditional Chinese medicine.
[23:25]
This was 2011.
[23:27]
And I found it really esoteric.
[23:29]
I found it was really yin yang, the seasons.
[23:32]
I found, wow, this is just really high level.
[23:34]
But then once you have wins and once you start to transform something inside of you,
[23:39]
you're like, wow, this is actually really powerful.
[23:40]
Let me try to understand it more.
[23:42]
And I find it's just always much easier to enter Eastern medicine from
[23:46]
a place of benefiting your system than from the theory itself.
[23:50]
And so when we started working with people with migraine,
[23:53]
our job was practical from the onset.
[23:55]
It's like, how do we prevent these attacks?
[23:57]
And how do we help people manage them better?
[23:59]
That's the sole goal of why we're here.
[24:01]
And I became really obsessed with understanding,
[24:03]
OK, what are we actually changing when we're managing these,
[24:05]
quote unquote, small miracles or changes?
[24:08]
What are we doing?
[24:09]
So I took a neuroscience class at Harvard X.
[24:11]
This was two years ago.
[24:13]
And I was really keen after the class of traditional Chinese medicine to also
[24:17]
understand the Western point of view of it all.
[24:20]
And so one of the things that stayed with me from studying neuroscience at Harvard X
[24:24]
is that the brain is never simply on or off.
[24:27]
Its activity is going to depend on a constant balance between excitation and inhibition.
[24:33]
And so signals that encourage neurons to fire and signals that restrain them.
[24:38]
And vision itself is another beautiful example of this complexity.
[24:42]
So light enters through the eye.
[24:44]
But what we experience as seeing is produced through an entire different pathway,
[24:48]
a visual pathway from the retina and optic nerve through the thalamus
[24:52]
and ultimately to the visual cortex at the back of the brain.
[24:55]
And so even there, the visual cortex does not work in isolation.
[24:59]
It belongs to a much larger network of interconnected brain regions
[25:03]
that constantly influence one another.
[25:05]
And this is where I find it interesting as a parallel with traditional Chinese medicine,
[25:08]
TCM also rarely treats the symptoms belonging to one isolated structure.
[25:12]
The eyes and the vision, for example, are traditionally connected with the liver system.
[25:16]
But the liver itself is understood as part of a larger network
[25:19]
involving blood and yin, yang, qi and other organ systems.
[25:24]
And I'm not suggesting that the liver system is the visual cortex
[25:27]
or that yin and yang are simply excitation and inhibition.
[25:30]
They are fundamentally different models.
[25:32]
But both ways of thinking invite us to move beyond the isolated symptom
[25:37]
and ask a much broader question of what network is this symptom emerging from
[25:41]
and what has shifted in the balance of that network.
[25:44]
And so silent migraine is a particularly striking example
[25:46]
because the visual disturbance we experience at the eyes
[25:50]
may actually originate much further upstream
[25:53]
within the changing activity of the brain itself.
[25:57]
And that is why in my first example,
[25:59]
I told the ophthalmologist or the optometrist are going to say your eyes are fine
[26:03]
because they are problem manifests in the eye.
[26:06]
That's a symptom challenge or the imbalance is inside the activity of the brain itself.
[26:11]
And look, of course, it's quite sophisticated.
[26:13]
But for me, it has helped put words and frameworks around a question
[26:17]
I've carried for years.
[26:18]
And why is it so difficult to understand something like migraine through a single lens?
[26:22]
And in many ways, Western medicine has become extraordinarily good
[26:25]
at isolating mechanisms, structures and extremes of possibility,
[26:30]
identifying the molecule, the pathway, the nerve, the lesion.
[26:33]
And each medicine has traditionally been much more concerned
[26:36]
about health versus disease and the balance,
[26:39]
the relationship and the way the whole body functions together
[26:43]
when it is well.
[26:44]
And when it comes to silent migraine and migraine more broadly,
[26:47]
I think we are standing right at the intersection
[26:49]
of those two ways of seeing the body.
[26:51]
It's almost impossible to capture the whole experience
[26:54]
through a purely Western model.
[26:55]
But I also would not want to understand it through a purely Eastern one.
[26:58]
My hope is that bringing the two together
[27:00]
sheds a bit more light on what may be happening.
[27:03]
Because ultimately, understanding the rationality of your body,
[27:07]
why it may be responding the way it is,
[27:09]
and the story those symptoms are telling,
[27:11]
is, I believe, one of the very first steps towards really lasting relief.
[27:17]
That's all for today.
[27:18]
I hope this episode added another piece to your migraine puzzle.
