What Is Alien Hand Syndrome Overview Alien hand syndrome is a rare neurological condition that causes one hand to act on its own free will. Sometimes one leg is affected, though this isn’t as common. With alien hand syndrome, the hand isn’t under the control of the mind and moves as though it has its own mind. The affected hand feels foreign to its owner during these episodes and seems to move deliberately to carry out tasks that are unintentional. While it can affect children, usually alien hand occurs in adults. It’s sometimes referred to as Dr. Strangelove syndrome, Strangelovian hand, or anarchic hand. What causes this? Alien hand syndrome can be caused by several factors. Some people develop alien hand syndrome after a stroke, trauma, or tumor. It’s sometimes associated with cancer, neurodegenerative diseases, and brain aneurysms. Alien hand syndrome is linked to brain surgeries that separate the two hemispheres of the brain. This may involve an incision along the corpus callosum. The corpus callosum divides the brain hemispheres and allows for communication between the two sides. Treatment options There is no cure for alien hand syndrome. Therapies and pharmacologic options for alien hand syndrome lack development, but scientists are working on treatments to reduce symptoms. People who have alien hand syndrome after brain illness or a stroke may recover after some time. However, recovery is less successful for people with neurodegenerative diseases. The condition may be treated or managed using muscle control therapies such as botulinum toxin (Botox) and neuromuscular blocking agents.
