Locked-in syndrome is a complex condition with many causes. People in this so-called pseudocoma can think, but they experience complete paralysis of all voluntary muscles. They can reason, but they cannot talk or move. While this condition causes whole-body sensory loss, some retain hearing, blinking, and vertical eye movement, allowing them to have a certain quality of life.


1. Types

There are three types of locked-in syndrome. The classic form consists of total immobility with the preservation of consciousness, vertical eye movements, and blinking. Incomplete locked-in syndrome is the same as the classic form but with minimal motor function. The third type is total immobility, which consists of complete paralysis, including loss of eye movement, with brain function only detected on an EEG.
