Crazy Psychologist

After Hu Peng left, Muchun leaned back in his chair and watched Xiao Xigua's updates for a while. She had been busy with charity hiking recently and had hardly posted any other updates.

Muchun looked at it and laughed, thinking that this smile was really interesting. Even another personality was so passionate about charity and so caring.

But Little Watermelon looks more cheerful and lively than Mu Xiao.

This is a bit strange. Dual personality should have a relatively big difference between the two personalities. Usually one is more depressed and the other is the opposite - cheerful, lively or even overly cheerful and lively, so that some impulsive behaviors occur.

The first two times he met Little Watermelon by chance, Mu Chun didn't notice that she was overly lively and cheerful.

Maybe the time is too short, maybe it's just a brief encounter and the Internet that still makes it impossible to understand what kind of personality the real little watermelon is like.

Finally taking a break from the continuous busyness, Muchun called Zhang Wenwen back.

As a result, no one answered the phone call.

Just as he was about to put his phone away and start reading Pan Guangshen's records, Mu Chun discovered that Mu Xiao had left a message for him, "Call me back when you are free."

So Mu Chun called Mu Xiao back. It happened that Mu Xiao had no patients at this time.

"It's the case of Zhang Wenwen's patient. I came to the outpatient clinic once and I've seen this case before." Mu Xiao said calmly.

This is a case of doppelganger. A patient said that he saw another self and a second or even third self.

It can be said that this is a not uncommon plot in human literature, especially some famous authors who seem to have a very strong and romantic interest in creating a work about doppelgangers.

Whether it is the outstanding horror novelist Edgar Allan Poe, the short stories of Maupassant, or the Argentinian writer Borges, there has been a protagonist who met another self.

Poe's hero stabs his doppelgänger only to discover that he is the one injured. Borges chases another Borges and finally discovers that maybe this is the same person.

The poet Eliot also wrote similar lines about the third person following him in "The Waste Land".

The poet Heine even created a poem about the doppelgänger.

If writers like doppelgangers and other literary materials, then from a medical point of view, this second existence of oneself can be regarded as some kind of "hallucination", more specifically, it should be called "out-of-body experience".

Many literary and film works and even legends will use a floating perspective to express this out-of-body experience. When people describe some near-death states, they will also say, "I felt a self leaving my body, and I saw myself lying on the ground." There, the doctors were busy around me. They looked at the monitor nervously and treated me nervously. I should be in pain, but I couldn't speak and I couldn't feel anything.

But the other me looked at everything that was happening to me with ease. I felt so helpless. I want to go into my body, I want to merge with myself, but it's not right, I can only look at the other me from the outside, that's it, the two me are exactly the same. "

This kind of thing has been circulating in human culture more than once.

Zhang Wenwen's patients may be influenced by such cultural works, or they may be obsessed with thinking about the dualism of mind and body, or they may be in a state of dissociation. For example, patients with schizophrenia may also experience similar hallucinations.

If it is not the case, or at the beginning of the examination, we should make a differential diagnosis of what this [hallucination] is. Why is the brain unable to integrate this state, and why does it build a complete body consciousness outside of itself.

Generally speaking, this extra body awareness makes people feel frightened and incomprehensible to those around them.

Theoretically speaking, almost every part of the body can have a "phantom part", but the brain cannot, that is, there will be no "phantom brain" because the brain is where the phantom part appears.

Judging from the situation of BIID patients, the situation of doppelgangers is more interesting. BIID patients will feel that they have an extra arm. That arm is not their own. It is almost similar to a [Cthulhu]-like existence. Full of weirdness, alienness, the unimaginable, and hostility.

No matter how complete it looks, no matter whether the arm has flexible joints, complete bones, or even clean skin, even if it is flexible, to BIID patients, this is weird and intolerable. They will hoard tourniquets and use them. Dry ice, they always imagine they have an extra arm - how terrible is this thing, how could it be on my body.

Even if they are very resistant to a part of their body structure, the consciousness of BIID patients is still retained in their own bodies. They will not appear to be conscious of that arm, or that part of my consciousness is also in the arm.

One is a state of isolation, and the other seems to be a complete copy. The latter feels that it is inhabiting a body outside the body, and that body is complete.

"Mu Chun, are you listening?" Mu Xiao's voice asked softly on the other end of the phone.

"I'm listening, so is it an illusion?" Muchun asked.

"With the problem of convulsions, I didn't tell Zhang Wenwen at the beginning." Mu Xiao said.

"Did you check his medical records?" Mu Chun felt that he was asking questions knowingly. It was obvious that either the patient had a convulsion while in the psychosomatic department, or else Mu Xiao must have learned from the patient that he had had a convulsion. The simplest The route should be medical records.

Mu Chun asked about the age at which the convulsion first occurred, and Mu Xiao said that the only time in the medical record was for the most recent convulsion, which was a month ago.

Considering that the patient was an adult and had no symptoms of hypokalemia or sodium, and ruled out convulsive reactions caused by high fever, Mu Xiao believed that intracranial infection or intracranial space-occupying lesions should be considered.

"But there have been no recurrences in a month." Muchun walked to the window sill and said while looking at Banxia.

"Yes, I asked the patient if he had another convulsion in the past month, and the patient denied it." Mu Xiao's voice hesitated slightly at this point.

Muchun helped her speak out, "Then we must consider intracranial space-occupying lesions."

"Well, yes, do you remember that case? We studied it in class before. A 22-year-old young man saw his body sitting in his office and playing on the computer. At that time, he wanted to stand up and leave his seat. , but he couldn't sit down. He was almost crazy. He couldn't sit down whether he wanted to return to that body or move that body. He was in a state of complete panic and out of control. I remember this is what the book said. .”
