Alien Hand Syndrome

Article #52 • Written by Alan Bellows

There is a very real, very disturbing, and very rare medical condition called "Alien Hand Syndrome" (AHS). An individual with this neurological disorder has full sensation in the rogue hand, but is unable to control its movements, and does not feel that it is a part of their body. The hand becomes personified, as if it has a will of its own, and its owner will usually deny ownership of the limb.

Though AHS was first identified in 1908, it was not clearly defined until 1972. Depending on the cause of the injury, the movements may be random or purposeful, and may effect the dominant or non-dominant hand. The symptoms are brought on by an injury to the brain, such as head trauma, stroke, tumor, or infection, but it can also be a side effect of a certain kind of brain surgery where the patient has the two lobes of the brain separated to relieve severe epilepsy.

As a side effect of brain surgery, or an injury to the corpus callosum (the area of the brain which connects the two halves of the brain), the movements are usually grasping motions in the non-dominant hand. When caused by head trauma, similar grasping and groping motions will often involuntarily occur in the dominant hand.

When the condition is brought about by a brain tumor, aneurysm, or a stroke, the alien hand may also engage in complex purposeful behavior, such as compulsive manipulation of tools, undoing buttons, or tearing clothes. Sometimes the sufferer is completely unaware of what the hand is doing until it is brought to his or her attention, or until they happen to see it themselves.

There is currently no treatment for Alien Hand Syndrome, but the symptoms can often be relieved by giving the rogue hand an object to manipulate, to keep it occupied.

It takes me back to the Far Side cartoon where the left hand is writing how much it hates the right hand while the right hand is juggling.

I am unfortuanate enough to suffer from this awful disease. Recently i strangled myself while attempting to tie my shoe, but fortunately my other hand could fight my alien hand off.

I'd just like to tell people about this awful condition and my hellish nightmare.

Cyril, I have a hard time believing you. But to be on the safe side best to start lifting weights with your 'other' hand, build up some strength for any future attacks!

It is absolutly true believe me, I wish it was all a dream but I have suffered with this condition for at least 53 years, as a small boy I accosted my grandmother twice and also tried to strangle the dog.

As a result I was put into an asylum for at least 12 years before the doctors realised this was a true condition. Even then I reoffended by choking my self in my sleep.

If this doesnt help you it will be a warning to others who suffer from my hellish nightmare...

all the best, Cyril.

Okay, I'm the first one to reply here in months, but I'm going to do it anyway. This article doesn’t explain why this syndrome occurs, and I might have some insight.

I saw a special about this disorder on the Discovery Channel some years ago, though I believe they called it by another name. The show was obviously memorable; it was so bizarre!

According to the show, those who suffered from (if I recall correctly) seizures were given brain surgery that would partially separate the communication between the two halves of the brain (though not completely, of course). The procedure generally worked to cure the seizures, but then a number of the patients experienced AHS. I’m not sure what percentage (it was probably very small), but one of the hands would act like it had a mind of its own and sometimes even try to strangle the person.

Why would this occur? The surgery used to partially separate the lobes would in theory separate part of the person’s consciousness, effectively giving them another personality trapped in their mind. However, this severed personality would not be able to access the rest of the body and would be a prisoner of the dominant personality. It’s conceivable the severed personality would be literally mentally disabled, not having full access to the faculties of the brain either. The personality would have alone in its control the ‘alien’ hand. That would explain why the alien hand would be capable in intelligent, complex behavior; why it would be independent of the dominant personality; and why it would try to strangle the body.

Creepy, isn’t it? Imagine being a prisoner in a body you have no control over!

Dude, I get the exact same feeling when i'm high. I might be holding something and i'll close my eyes for a minute and open them up again, and i'll just be staring at my hands but have the feeling of being unable to move them. It's really cool, I feel disconnected from my hands when i'm high. It only seems to be my hands though, not legs or anything. It would suck to be a long term condition though.

This AHS is really strange, I just could'nt live with a a alian hand. I mean when your sleeping, it could strangle you. Very frightfull, i may be only 12 but i think most people who write comments on here (example cyril) i couldn't belive you had to "fight it off wit your other hand".

This may sound purely made, but if i had AHS i would have my arm/hand amputated!

I could not live with a hand wit a mind of its own.

strait up. the whole time i read i was thinking that i would do that but i guess that you would have to have your arm amputated also seeing that if you were to chock your self then you would use your arm too

its very believable to have this syndrome. I'm currently using this ailment as my major point of research for high school psychology and according to scientist it occurs due to extreme damage to the corpus callosom, the connective tissue between the two hemispheres of the brain, and is described as the person has an attached limb that has a mind of its own. Best example other than Dr.Strangelove is from Futurama Episode: The Devil's Hands are idle play things.

Aside from a surigcal or trauma-related severing of the corpus callosum, it may also be caused in lesser forms by brain tumors or aneurysms.

This is a sucky disease. My hand will wander off without me noticing and i'll be touching random people... Not good. I need a half straight jacket or something, or maybe just a really hard high five to knock some sense into my hand.

I'm not sure where you are in your relationship with God, but I do know this: he has the power to heal you of any wrong, whether it is of spiritual or physical origin. Just put your life in Jesus's capable hands, and he'll take care of the rest!

does any one know if there is any connection between this syndrome and Dissociative Identity Disorder (formerly known as: Multiple Personality Disorder)? because, I'd Guess that either the hand embodies Your own Id (as in Dr. strangelove); OR, the hand would be a potentially homicidal (or suicidal) Subpersonality, if anyone could shed some light on my query, I would be filled with a varitable conucopia of Joy for the Love of Knowledge.

Very interesting. We covered this topic in Stage 2 Psych (and it was just as odd and fascinationg then too).

I just wish some of these articles were a bit longer. Seems like I'm just getting into the topic when it ends (A couple of articles - such as the "tongue snatcher" one, are little more than a paragraph - C'mon, that's just teasing... ^_^ ). Still, often other links get provided by other members, which can provide interesting additional material.

These symptoms may be the result of a trivial injury. But a man who reaches higher or ultimate stages of mental and spiritual development will suffer from the similar symptoms. I.e. if we base on Indian Traditional medical school principles, the one to reach such a stage subtends that his Kundalini energy has mounted from lower chakras to the temple. I.e. he has transformed his sexual energy into a more pure one. This, has it's results: the person does not depend on his physical body anymore. He ad verbum lives in his mental body, or one of the "thin" bodies. The positive points are: he does not feel thirst or hunger, for instance. The negative point is the energetic disbalance inside his physical body. The risks of major diseases increase as a result. Malignant swelling risks are high. As the physical body begins to degenerate, In the late stages of this process control of psycho-somatic processes is almost always partly lost. So the same symptoms as listed by Alan are evidenced.
Many Gurus In India have such facts in their biography. Their physical bodies were of no necessary use to them.
The shortest way to such a no-return point is Mahasamadhi. It means a two-week ecstasy and physical death as a result.
Among the Buddhists there is the example of Bodhidharma (he brought the Dharma to China from India ). He lost control over his legs, so his fosterlings had to carry him.
Interesting to me that what is usually the result of a handicap can be a result of a very high level of mental and spiritual development.

"The symptoms are brought on by an injury to the brain, such as head trauma, stroke, tumor, or infection"

I think you should probably get to a doctor.

On amputating an AHS limb:
I've heard that some people have been able to kill a lot of the flesh on the limb by holding it in a vat of dry ice or something similar, forcing doctors to amputate. It's a bit drastic, but at least it gets the professionals involved in the whole thing. I don't think that many American insurance companies would want to cover that, though.

I am a woman, aged 54. I am speaking of something that happened a few times when I was pre-teen and into early teen years. First just a little background. I come from a old deep south family, and my mother and father were closely related...the families had been related for over a hundred and fifty years in one way or another. Second, my family was violent and my mother was diagnosed paranoid schizophrenic by the same doctor who treated the woman in the true story 'Three Faces of Eve'.
Although he had a different name in the movie, his real name was Dr. Thigpen. Third, we were the black sheep tribe in that family--my father set steel on bridges, so we moved plenty and often. I was very socially outcast when we finally settled down enough for me to go to high school, and for my mother to recover from shock treatment. I did not fit in in high school. I would not have fit in during a more normal time, but it was the time that the high school was integrated. I got beaten up often by both black and white kids. Once a big girl, wearing her boyfriend's initial ring, hit me so hard that the impression of a 'D' remained on my cheek until the bruises faded. My father hit us often and not just spankings, but really hit us.
Okay, background over.
I began to wake up, thinking myself under attack. A hand would be grabbing at me...grabbing my hair and tearing my clothes, and grasping to catch hold of my throat and choke me. I never immediately knew that it was my hand. I was busy fighting with my other hand to pull it off me. It was my left hand that attacked. I am right handed. I would be rolled out of bed on the floor and fighting for my life I thought. Eventually, I would be holding on to the wrist of that hand, and I would view it and realize, and say to myself...'that's my hand.' And the attack would stop. The hand would stop trying to hurt me. My mother and father never saw these attacks. They heard me screaming and fighting, but I always had the door locked and barricaded. I was afraid of both my violently insane father and my crazy as a loon mother, who slept with a shotgun under her mattress, no lie. I didn't want to come in when I was asleep. So they thought it was a nightmare. Eventually, they took me to a shrink. I was crazy like a fox. I knew that a psychiatrist had put my mother in an institution. I didn't want to go there too. I told that doctor I had trouble with boys and zits. I didn't even mention being a punching bag at school. I certainly didn't mention that I was choking myself.
To myself there seemed to be 2 explanations. I thought maybe I could be possessed by Satan, but even back then it didn't seem too likely. The explanation that I gave myself and believed is more sad than that: I decided that I was so miserable that I wanted to kill myself, and because I was too chicken to do myself harm while awake, I was trying to kill myself while asleep.
I do not remember how many times this happened. Not over 10, and maybe not as many as 5. But definitely more than once or twice--and enough to make my extremely negligent parents concerned enough to get me to the doctor about those 'bad dreams'. My mother also blamed the daytime soap opera 'Dark Shadows' which featured a vampire called Barnabas Collins.

Needless to say, I married very early, by the end of my 16th year. By then it had stopped happening, but until I was 20 I had periodic episodes of sleep paralysis, the last time being when I was pregnant with my first child at 20, and never again after that. Except for physical abuse I was a healthy child and not sick or hurt, except for a near death experience after a timber-rattler bite.

I told my story through out my life to different people, but never knew about Alien Hand Syndrome until I was watching a episode of 20/20 back in the mid nineties. Then I realized what had happened to me all those years ago, and how fortunate that it was a passing thing. But I have some curiosity left...could it have been caused by all the knocks in the head I got? Could the rattlesnake bite have caused it? Could it have to do with the fact that my grandparents were double first cousins and my parents second cousins? Could I pass this along to my daughter and grand kids? And can it return.
I am now diabetic and some times see things when I wake up at night, but these things are benign, not scary, but I have a niece who thinks she is possessed and often has to be restrained to keep from doing physical damage to herself. Basically, I am okay now, and am a lucky woman really. I just would like some answers, and almost all the websites about AHS are filled with medical jargon that eludes me.

interesting story. not being rude but i have had sleep paralysis and i love it... i never dream of anything bad though because i have a dreamcatcher above my head when i sleep so i have that whole placebo effect... but it happens naturally and i can even trigger it. usually i have really vivid semi-lucid dreams if not fully lucid
