Summarize this article for a 10 year old
Locked-in syndrome (LIS), also known as pseudocoma, is a condition in which a patient is aware but cannot move or communicate verbally due to complete paralysis of nearly all voluntary muscles in the body except for vertical eye movements and blinking.[3] The individual is conscious and sufficiently intact cognitively to be able to communicate with eye movements.[4] Electroencephalography results are normal in locked-in syndrome. Total locked-in syndrome, or completely locked-in state (CLIS), is a version of locked-in syndrome wherein the eyes are paralyzed as well.[5] Fred Plum and Jerome B. Posner coined the term for this disorder in 1966.[6][7]
