Incidence of Clinically Significant Responses to Zolpidem Among Patients with Disorders of Consciousness

Abstract

These results confirm that clinically significant responses to zolpidem among individuals with disorders of consciousness do occur in a minority of patients and can be replicated. Failure to find a trend toward improved performance on zolpidem among nonresponders suggests a bimodal rather than a graded response to the drug. The fact that only one drug responder was identified in this small study prevents assessment of features characteristic of drug responders.
