Locked-In Syndrome
A rare neurological condition characterized by complete paralysis except for eye movements, with preserved consciousness and cognitive function.
Full Definition
Locked-in syndrome is a rare neurological condition typically caused by damage to the brainstem, particularly the pons. Patients retain full consciousness and cognitive abilities but experience complete paralysis of voluntary muscles except for vertical eye movements and blinking. This creates a situation where patients are mentally alert but unable to speak or move their body. Communication is typically established through eye-coded systems or brain-computer interfaces. The condition presents unique challenges in rehabilitation settings, requiring specialized communication methods, extensive family education, and complex care coordination for long-term management.
Usage
Usage note: Often misdiagnosed initially as coma or vegetative state due to apparent unresponsiveness.
