Normal human consciousness requires brainstem, basal forebrain, and diencephalic areas to support generalized arousal, as well as functioning thalamocortical networks to become aware of, and respond to environmental and internal stimuli. Injury to or disconnection of these interconnected systems, typically from cardiac arrest and traumatic brain injury, can result in disorders of consciousness, including coma, vegetative state, minimally conscious state, and akinetic mutism. Similar brain injuries can also result in loss of motor output out of proportion to consciousness, resulting in misdiagnoses of disorders of consciousness. We review pathology and imaging studies and derive mechanistic models for each of these conditions, to aid in the assessment and prognosis of individual patients. We further suggest how such models may guide the development of target-based treatment algorithms to enhance recovery of consciousness in many of these patient.
