Alien hand syndrome is a rare neurological disorder that results in a person feeling like they have lost control of their hand or arm. The affected limb can even seem to be acting on its own accord, performing actions that the person doesn't intend or want to do.

Alien hand syndrome is usually caused by damage to the corpus callosum, which is a thick band of nerve fibers that connects the two hemispheres of the brain. This damage can occur as a result of a stroke, traumatic brain injury, or other neurological condition.

In some cases, alien hand syndrome can also be caused by psychiatric conditions, such as schizophrenia.
