Alien hand syndrome, also known as anarchic hand or Dr. Strangelove syndrome, is a neurological disorder that causes one hand to seemingly take on a life of its own, performing movements and actions independent of the person's control. Some other synonyms for this condition include apraxia of volitional movement, disobedient hand syndrome, and wayward hand syndrome. These terms describe the uncontrollable nature of the hand movements, which can interfere with daily tasks and social interactions. It is thought that this syndrome is caused by damage to the corpus callosum, the part of the brain that connects the two hemispheres, leading to a lack of communication between the two sides. Treatment options include physical therapy, medication, and surgery in severe cases.
