Recovery of good long-term consciousness is possible. A low level of consciousness recovery and the early development of severe and persistent symptoms of dysautonomia associated with hypertonia could be linked to poor long-term outcome.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
