Alien Hand Syndrome: A Disease In Which Your Hand Becomes Your ‘Enemy’

Somebody is strangling you. You wake up and see that what you felt is true but to your surprise, the suffocating hand is your left hand. You are not able to stop it even if you want to, it is not in your control, and it is not in your control. With great difficulty, you release each finger from the throat with your right hand, as if you have freed your throat from someone else’s hand.

What Is Alien Hand Syndrome?

Imagine, you are lying comfortably on a chair. It has caught your eye that you wake up feeling the tightness of someone’s hand on your neck. Somebody is strangling you. You wake up and see that what you felt is true but to your surprise, the suffocating hand is your left hand. You are not able to stop it even if you want to, it is not in your control, and it is not in your control.

With great difficulty, you release each finger from the throat with your right hand, as if you have freed your throat from someone else’s hand. This happens when the lower part of the frontal lobe, the frontal lobe of the brain, is damaged. In addition, there is damage to the anterior part of the corpus callosum. The Corpus callosum is a bridge of nerve fibers that connects the right and left cerebral hemispheres, information is exchanged between them. Work is coordinated. When the bridge is damaged, this relationship gets severed and the hand itself becomes a stranger. This is called alien hand syndrome.

A Case Study Of Alien Hand Syndrome

The patient is sitting on the office table writing something with a pen in his right hand. Then without her wish, without her realizing it, her left hand comes and clutches the glass of water kept on the table. He acts like a stranger. The distorted action of strangulation is the format of this. In some patients, this alienation of the hands is to such an extent that they work opposite to each other. The right hand is buttoning the shirt and the left hand is opening the button. The right hand is trying to lift the glass while the left hand is stopping it. If the right-hand wears the sock, then the alien hand takes it off. Such opposing processes usually occur when the corpus callosum is damaged.

A woman used to have severe epileptic seizures since childhood. When the seizures did not come under control with medicines, the doctor operated and cut off the corpus callosum. The epileptic seizures were cured. Went to see the doctor. Hatat Doctor ‘Hey! What are you doing why are you unbuttoning the blouse? The woman was not aware that one of her hands was opening the button. Shivering, he closed the buttons with the other hand. By the time she spoke to the doctor, her first hand again started opening the button.

This part of the brain is supplied with blood by the anterior cerebral artery, which when blocked (thrombosis) leads to stroke in this part, resulting in alien hand syndrome. Left hand in right-sided stroke and right hand in left-sided stroke.
