[Medical Human Story-Episode 62]:A Fleeting Silence, The Brain’s Final Warning (The Silent Warning)_2
Part I: The Hand That Froze on the Mahjong Table
The Hospital at Dawn, and Two Images
The hospital at dawn is always the same.
Under fluorescent lights, everything turns equally pale.
The air settles cold and heavy.
And I—
must make the most critical decisions in that silence.
That morning, two images lay on my desk.
One belonged to a 75-year-old woman.
The other to a 44-year-old man.
Two people who had lived completely different lives.
But the images told the same story:
“It has already begun.”
What the MRI Revealed
I picked up the MRI of the 44-year-old patient.
Diffusion-weighted imaging (DWI).
The most sensitive method for detecting acute ischemia.
On the screen—
small white spots were scattered.
They could look like stars in the night sky.
But I knew.
They were not stars.
They were—
a damaged brain.
The Invisible Attack
Each white spot carried meaning:
- A micro-embolus
- A transient blockage of
blood flow
- A neuronal injury
And when they accumulate—
a future collapses.
Outwardly, he appeared fine.
He walked in.
He spoke normally.
But his brain—
had already been attacked multiple times.
The Patient: Mr. Park
His name was Mr. Park.
44 years old.
An ordinary office worker.
And—
a heavy smoker for over 20 years,
more than a pack a day.
I reviewed his history again:
- Recurrent right-sided
sensory disturbance
- Transient motor weakness
- Increasing frequency over
the past two months
A classic pattern.
So classic that it was frightening.
The First Incident
“Doctor, at first, it was almost funny.”
He began with a faint smile.
“I was playing mahjong… and when I tried to pick up a tile, my right hand
just wouldn’t move.”
I looked at him quietly.
He was smiling.
But I could not.
“It lasted about five minutes… then it went away. So I just ignored it.”
The Meaning of Five Minutes
He spoke lightly of those five minutes.
But in my mind,
they were calculated differently.
During those five minutes—
- A region of his brain was
deprived of oxygen
- Neural transmission was
interrupted
- Cells approached their
survival limit
He was lucky.
That day.
The Second Ignored Warning
“And after that?”
I asked.
He hesitated.
“Sometimes… my hand felt strange. But I thought it was just fatigue.”
Then he added:
“My blood sugar was high at a check-up… but I figured I’d just take
medication eventually.”
I sighed inwardly.
The warning had already come twice.
And he ignored both.
The Storm Begins
Then came the turning point.
“In the last two months… something felt wrong.”
His voice trembled for the first time.
“At first, once a week… then later, several times a day…”
“How many times?”
“…Up to six times a day.”
The Repetition of 10 Seconds
Each episode was brief:
- 10 seconds
- 20 seconds
- At most, 30 seconds
And then it disappeared.
So he endured it.
But I knew what this meant.
“This is not simple TIA.”
This is—
“an ongoing catastrophe.”
The Second Truth Revealed by Imaging
I reviewed his MRA once again.
Magnetic Resonance Angiography—
a study that visualizes the structure of blood vessels.
And there—
I found the problem.
A Narrowed Path
The left middle cerebral artery (MCA).
That vessel was abnormally narrowed.
Not a normal diameter.
A structure where blood could not flow freely.
I spoke quietly.
“Do you see this?”
He stared at the screen, unable to interpret it.
“This vessel… is quite narrowed right now.”
The Highway Analogy
I continued my explanation.
“Think of this as a highway.”
“Right now, this road is under construction. The lanes have been reduced.”
“What do you think happens when cars try to speed through in that
condition?”
He paused for a moment.
“…It gets congested?”
I nodded.
“And some are forced out of the flow.”
Micro-Emboli
What gets “pushed out”—
those are micro-emboli.
• Tiny clots that detach from the vessel wall
• Travel along the bloodstream
• Temporarily block distal vessels
And in that moment—
his right hand stops moving.

My Conclusion
I no longer hesitated.
This was clear.
• Recurrent TIA
• Multiple DWI lesions
• MCA stenosis
When these three come together—
there is only one diagnosis:
“High-risk recurrent TIA.”
The Time He Had Left
Leaning back in my chair, I said,
“Mr. Park.”
He looked at me with tense eyes.
“This is not a minor issue.”
A brief silence.
Then I spoke clearly:
“You are… on the verge of a stroke.”
The Moment the Air Stopped
His expression froze.
The smile disappeared.
His eyes trembled.
Only then did he begin to understand—
this was not just “tingling.”
The Role of a Physician
At moments like this, I always face the same choice:
• Reassure the patient
• Or confront them with reality
I choose the latter.
Always.
Because—
only the truth can save a life.
The Final Warning
“Next time… it may not come back.”
I spoke slowly.
“Next time, it may not be ten seconds—
it could be a lifetime.”
He said nothing.
Time to Decide
As I reached for the admission form, I said,
“You need to be hospitalized.”
“We need detailed evaluation… and to identify the exact cause.”
He nodded.
This time, without hesitation.
The War Begins
That day,
Mr. Park’s treatment began.
But it was not merely treatment—
it was the beginning of a war.
A fight against an invisible enemy.
A fight against time.
And—
a fight against his own choices.
And I Already Knew
This would not be a simple story.
Because—
on that very same day,
another patient was being brought into the emergency room.
A 75-year-old woman.
Recurrent paralysis.
And—
cerebral vessels already nearing their limit.
