Disorders of Consciousness.

Disorder of consciousness (DOC) is a state of prolonged altered consciousness, which can be categorized into coma, vegetative state, or minimally conscious state based on neurobehavioral function. The pathophysiology of DOC is poorly understood but recent advances in neuroimaging and advanced electrophysiological techniques may provide an improved understanding for the neural network involved with consciousness. The primary aim of DOC rehabilitation programs is to promote arousal while preventing secondary medical complications while providing education and training to families. Treatment interventions include both pharmacologic and nonpharmacologic programs, but there are currently no consensus treatment guidelines for individuals with DOC. Published by Elsevier Inc.
