Locked-in syndrome is a rare neurological condition in which a person is aware and awake but unable to move or speak, except for some limited eye movements. It is typically caused by damage to the brainstem, often due to a stroke, traumatic brain injury, or disease. Individuals with locked-in syndrome are often completely paralyzed, with the exception of their eyelids, and are unable to communicate verbally. Despite their physical limitations, their cognitive abilities remain intact, leaving them fully aware of their surroundings and able to process sensory information. Treatment for locked-in syndrome typically focuses on communication techniques, such as eye-tracking devices and other assistive technologies, to help individuals communicate with others.
