The Syndrome That Makes Your Hand Want to Kill You

A hand crawls towards you with its sprawling fingers, grasping and grabbing around, lunging at you. Sounds scary, but this phenomenon becomes more terrifying when the hand belongs to you, out of your control. While this feels like something out of a horror movie, the neurological condition called Alien Hand Syndrome is quite real. What could be causing this terrifying phenomenon? Is your hand possessed, or is something more sinister at play? Let’s get into it!

When I was nursing I had a patient with this condition. We had to make sure her hand was tied down at all times. If it wasn't it would start to tear her hair out. By the time she died, she was almost entirely bald. I'll never forget that lady, everyone just felt so horrible for her.

​@@DarkWarchieffthere's another syndrom where the body doesn't recognize the limb (as in you can't close your eyes and touch your nose with it), or part of the limb to a very specific point.

[@lhamagalopante6735]

The brain can sometimes compensate, especially in congenital cases, for abnormalities in very extreme levels! There's a woman that was born without a cerebellun and didn't find out untill much later. Her brain had shifted the functions around and accomodated enough that there weren't many noticeable neurological impairments at all.

[@vprovisngkate3853]

From my understanding, it's not the hand teaching it's victims any good morals or just torturing them, it's doing the opposite of an assigned task. The woman wants to keep her shirt buttoned up, but the rebellious hand doesn't. She wants all her stuff in her purse, the hand wants it out. She smokes, hand oppose. She swears, hand scares. It's like thinking about doing something but having second thoughts is controlling a part of your body.

Left hand, right brain. The right hemisphere is responsible for more abstract thought and creativity. You don't realize how much either side of your brain acts because they are working in unison. The left side doesn't control the right but brings order to the left's more chaotic elements. Take that away, all you have is the more chaotic part without the grounding it needs to function well.

[@Hamhockss]

​@MollyHJohns I mean it is using half a brain.

[@Pining_for_the_fjords]

Since the hand was able to perform complex, seemingly purposeful actions, I wonder if the part of her brain controlling it was conscious like her. Like her consciousness was split in two, and the side controlling her hand was just trying to communicate with her. Sure it's bad waking up and finding your hand is moving by itself, but maybe from her hand's point of view, the whole rest of her body was walking, talking and doing everything else by itself.

[@Yetta_]

That’s creepy

[@Craxin01]

You're thinking about it wrong. Left and right hemispheres are built to function together, constantly communicating. With the corpus collosum cut, all communication between the two hemispheres ceased. You don't realize just how different both hemispheres are because how much they work together. Rational thinking, logic, understanding, language, all on the left hemisphere. The right deals with abstract thought, creativity, emotion. With the two hemispheres essentially isolated, the left wasn't able to communicate with the outside world. It wasn't trying to communicate with her, it is her, just as much as the right side is, but it no longer the outlet it needed, and so didn't really understand things. That's why her left hand, controlled by the right hemisphere, seemed to behave so irrationally. It's because it was literally incapable of rational thought.

[@TheLithp]

@@Craxin01 No, Fjords is actually onto something. Experiments done with split-brain patients seem to indicate the hemispheres are separate entities. The way they do this is to show questions to only one eye & give the corresponding hand a pad to answer. The left eye/hand are controlled by the right hemisphere & vice versa. A commonly-used example is a patient where one hemisphere claimed to be a Christian & the other an atheist.

[@jackalzirson2631]

​@@Craxin01 Dunning kruger effect

[@jth4242]

@@TheLithp Yes, and lateralization doesn't mean that one thing is only in one hemisphere with 100%. Also, even without language and rational thought, you would still be conscious - unless you'd argue that animals and severely mentally disabled people aren't conscious. I would think it plausible that aggression from the "alien hand" is a fear reaction of the isolated (and likely language-impaired) hemisphere no longer being able to grasp what's happening on it's own.

My dad asked about it and I explained what happened. I know there was a nightmare involved. I don’t really remember the nightmare itself but I do remember that it had to do with an alien hand in the clothing section of a store. I don’t remember which store, but I do remember being scared. It took me a few days to start trusting my hand again. It’s been fine since.

Maybe that was just a manifestation of sleep paralisys, far more common than AHS and also incorporates sensations of being choked, asfixiation and incapability of screaming. Regardless, I'd talk to a neurologist and maybe get some exams done.

In some experiments where they severed the connections between left and right hemispheres they had weird results. Basically each half of the person would see things differently. There was one suggestion of the result saying each person has two parts of themselves, but only one hemisphere is your conscious self, only communicating with your other self, and there’s another fully conscious part of yourself that you aren’t aware of that has no direct control over you. If applied to this situation, maybe she should’ve tried understanding herself better instead of shutting it up. I wonder what’d happen if you gave the hand a pen and paper

[@ziqi92]

I wonder what’s the mechanism behind these AHS attacks. Trying to asphyxiate yourself or unbuttoning your shirt is such a specific action. Is the alien hand acting on intrusive thoughts?

[@Mantras-and-Mystics]

[@DanksterPaws]

Im convinced cutting the connection between the two brain hemispheres creates another consciousness that can’t talk. I always wonder why they don’t ask the other hand to write down what it wants? From some of the experiments I’ve seen the other hemisphere can still see, maybe even with just one eye. Though I’m sure the effects are always different from person to person. Though I would assume a hand still knows how to write somewhat even if blind. Unless writing is only a memory of one hemisphere?

[@soniccd9983]

​@ChonkedCat technically you don't. You ask a brain half

[@Craxin01]

Less a separate consciousness and more a disjointed one. For one thing, writing is a left-brain function and the right brain, which controls the left hand, cannot write. It's also not technically speaking, blind. The right brain also controls the left eye, but it deals with visual information differently. Less cognition, more emotion. Sometimes, speaking aloud to "inform" the right-brain can help control the symptoms of AHS, making it less of a passenger. You just don't realize how different both hemispheres are and how much they need to communicate.

Man.....wow. Ya know, I was born with epilepsy, but my doctor once said, "See, Darren's case is an interesting one. He has what I would call a 'mild case' of epilepsy." Yeah, I mean, when I was a kid, I'd have the occasional seizure, but they weren't Grand Mal or anything severe. Mine were always just a 3-5 minute black out and slight shaking, then I'd come to again. On a somewhat humorous note, at a few parts during the video, I found myself chuckling a little bit, because I kept thinking about that one part in the opening sequence of the old A-Team TV show, where Murdock is being wheeled out of a hospital, and he's all holding the wrist of one hand with the other. The claw! The claw!!!! heh!

Imagine. One day you wake up. It seems like everything was normal, until you realize your body is moving on its own and you're just watching through your eyes. Your mouth was talking, you are walking but you are not commanding your body to walk, you are talking to your family, greeting them a good morning. You are panicking but your body is not reacting the way you'd expect, in fact, it's like you're watching through the eyes of someone else, and that person is having a normal day. You're trapped inside someone's mind, and that someone is pretending to be you. Then, you realize, you have control over your right arm. By instinct, you wanted to get that entity controlling your body to get out of it, so you start punching yourself. You don't feel the pain, but the one who "possessed" you is panicking and screaming. You desperately fight for control but you are at a disadvantage because all you can control is your right arm. What if this condition actually makes a clone of you which is stuck inside your brain and is just able to control one of your limbs? What if that person, who is an exact copy of you and has your memories up until the time they are "created," is just as scared and confused as you are when when your hand moved on its own? Pretty Black Mirror-ey...

I would hazard a guess that the limbs doing something the main hemosphere doesn't want is just the other hemosphere trying to highlight a problem it's detected but is unable to communicate to the main hemosphere in most cases since the 2 are supposed to work together to direct the body towards shared goals. I would suggest that the doctors also investigate the places the limbs try to highlight in some way for things that should not be there, such as the pin or whatever a girl stepped on in a older video.

Really makes the octopus that much more fascinating, sense it has 8 of these independent capable limbs. Makes you wonder though how it's limbs can preform independent tasks that benifet the creature as a whole.? It would seem it would be the best being to study to learn the mechanism(s) at play.

I could never bear losing control of my left hand. Thats my dominant side. I wouldnt be able to write, draw, crochet, sew, or feed myself ever again. I suppose i could try to learn with my right, but having a hand that sabotages me might make that difficult. I hope i never experience that.

[@limsalalafells]

van Wagenen and Herren first proposed the corpus callosotomy (CC) as a surgical procedure for epilepsy in 1940. It seems this is related to the procedure you described yet not mentioned.

[@Craxin01]

I just learned that's the name of the procedure. Odd. Callosotomy brings the other end of the body to mind.

This makes me think if raising the back of ur feet or ur heel slightly upwards and then it starts shaking up and down has something to do with the brain not able to control it.

When it comes to the split brain variant of alien hand syndrome, it isn't just that it seems like an independent entity, it is an independent entity. It's just because the left brain monopolies language that the behaviour of the silent right brain is seen as a mindless aggressor. In truth BOTH the left and right brain constitute half of the original person each. They are both conscious automous entities. We just identify with the one that speaks because it conveys complex ideas efficiently while the other is silent and seemingly disruptive. The really interesting part in this split brain case is that the verbal response you get is only from half of the original person, the other half is silent and is often very frustrated with not being listened to. Just imagine what it would be like if you woke up from your split brain procedure to find that you are the silent half brain, and then spending the rest of your life not being listened to or your intent taken seriously.

[@spindash64]

So what you’re saying is, verbally acknowledging “Lefty” could make it less likely for Lefty to lash out? Or maybe they’re Righty, I’m not really sure…

Were there any attempts to communicate with the hand? It might understand verbal input should be encouraged to point to symbols to communicate. It might be controlled by some uncoscious part of the brain.

“Why are you hitting yourself?”

[@G0thCrayon]

If your left hand was afflicted, and you wore an eye patch and an earplug on the side governing the afflicted hand... and assuming the hand doesn't just straight-up tear off the eye patch and yank out the the ear plug... Would patch-n'-plugging effectively blind/deafen the hand and render it ineffective/docile? Or (more likely) would it just tick it off and resort to the classic retribution of a midnight snack consisting of a Ziploc full od spiders?

[@cheatemperor8583]

From the fact it responds from stuff you see it must have access to your eyes, so maybe that could help in a fps where it could aim for you

Unless it's the emotional half of your brain, then it would probably just get frustrated and keep getting worse as it gets more upset.
