MRI in disorders of consciousness
Current Opinion in Neurology, 2020Purpose of review In the study of brain-injured patients with disorders of consciousness (DoC), structural and functional MRI seek to provide insights into the neural correlates of consciousness, identify neurophysiologic signatures of covert consciousness, and identify biomarkers for recovery 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 ...

Global disorders of consciousness
WIREs Cognitive Science, 2013In recent decades there has been a great deal of interest in global disorders of consciousness, such as the vegetative state, the minimally conscious state, and epileptic absence seizures. Global disorders of consciousness pose significant challenges to consciousness science in that the ordinary pretheoretical criteria for the ascription of ...

Disorders of consciousness (DOC) place numerous challenges to healthcare professionals and clinical investigators, as they involve a variety of pathophysiological mechanisms, which are not yet clearly understood. Research studies have been conducted for promoting a better comprehension on these neurological conditions and making progress on diagnostic ...

Abstract Consciousness may be defined as a neurological state in which one is fully awake and aware of self and environment and has normal responses to external stimulation and inner needs. Unconsciousness is the opposite; it is a neurological state of overtly diminished responsiveness to environmental stimuli and unawareness of self and

Coma and disorders of consciousness
2013Patients in coma, vegetative state/unresponsive wakefulness syndrome, and in minimally conscious states pose medical, scientific, and ethical challenges. As patients with disorders of consciousness are by definition unable to communicate, the assessment of pain, quality of life, and end-of-life preferences in these conditions can only be approached by ...

Delirium: A disorder of consciousness?
Medical Hypotheses, 2013Delirium is recognised as a disorder of consciousness, however, no evidence has been previously generated to specifically address this premise. In order to evaluate this established notion, we have attempted to review consciousness, the components of consciousness and the emerging evidence for neuroanatomical correlates and then relate this to the ...

Electrophysiology and Disorders of Consciousness
2012Electroencephalography offers different insights into brain activity useful in the study of disorders of consciousness. In this paper we focus on three aspects of electroencephalography, namely standard clinical assessments, event related potentials (ERP) and quantitative electroencephalography (qEEG).

Chronic Consciousness Disorders
Annual Review of Medicine, 2009Although philosophers and cognitive neuroscientists have struggled to define human consciousness, physicians can identify and assess its two clinical dimensions: wakefulness and awareness. A comatose patient has neither wakefulness nor awareness; a patient in a vegetative state has wakefulness without awareness; and a minimally conscious patient has ...

The vegetative state and other so‐called disorders of consciousness present some of the most significant practical and ethical challenges in modern medicine. It is extremely difficult to assess residual cognitive function in these patients because their movements may be minimal or inconsistent, or because no cognitive output may be possible.
