Quizplus · Accepted Answer

Locked-in syndrome is a condition where the individual has lost voluntary movement of all or almost all their muscles, but their autonomic functions remain intact. This often occurs after a stroke or other trauma to the brainstem. The individual is "locked-in" to their body, unable to communicate or move voluntarily, but still aware of their surroundings. Option A describes catatonic behavior, and options C and D describe different types of movement disorders.
