Alien Hand Syndrome is a neurological condition that is still being studied in the fields of neurology and psychiatry. A better understanding of this syndrome may help us understand the complex functioning of the brain and how sensory perception is shaped. Additionally, examining this syndrome may contribute to improving the consequences of brain injury and rehabilitation methods.
What is Alien Hand Syndrome?
Alien hand syndrome (FES) is a rare neurological condition in which a person is unable to control one of his own hands as if it did not belong to him. Alien hand syndrome can cause significant difficulties in daily living. Symptoms are often permanent, but treatment can help relieve symptoms and improve functionality. This condition usually occurs as a result of brain damage, and is particularly associated with lesions in the brain structure called the corpus callosum. The corpus callosum is a bundle of fibers that connects the two halves of the brain and plays a critical role in information transfer. Causes of Alien Hand Syndrome are:
- Damage to areas of the brain such as the parietal lobe or frontal lobe
- Stroke
- Glioma
- Celebral hemorrhage
- Infection
- Trauma
How to understand Alien Hand Syndrome?
Alien Hand Syndrome is a rare neurological disorder. In this syndrome, one or both hands of a person are perceived as not belonging to them and they may exhibit uncontrolled behavior. For the question “What are the symptoms of Alien Hand Syndrome?”, the symptoms of Alien Hand Syndrome are as follows:
- The foreign owner may act beyond the owner’s control. These movements usually occur involuntarily and unwanted by the owner. For example, the foreign hand can hold objects, press buttons, or move on its own.
- The foreign hand can move on its own without being guided by the owner. This situation may occur when the person thinks that his own hand does not belong to him and he cannot control it.
- There may be conflicting desires between the hand directed by the owner and the foreign hand. For example, when the owner wants to hold an object, the foreign hand may want to let go of this object or do something different.
- The person may experience some kind of conflict between the movements of the foreign hand and the owner’s hand. In this case, the person may try to regain control of the foreign hand or make an effort to stop the movements of the foreign hand.
