MRI in disorders of consciousness

Current Opinion in Neurology, 2020
Purpose 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.

Heart rate variability for the evaluation of patients with disorders of consciousness.

Clinical Neurophysiology, 2023
OBJECTIVE Clinical responsiveness of patients with a Disorder of Consciousness (DoC) correlates to sympathetic/parasympathetic homeostatic balance. Heart Rate Variability (HRV) metrics result in non-invasive proxies of modulation capabilities of visceral

Global disorders of consciousness

WIREs Cognitive Science, 2013
In 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 ...

Mesocircuit mechanisms in the diagnosis and treatment of disorders of consciousness.

Presse medicale, 2022
The 'mesocircuit hypothesis' proposes mechanisms underlying the recovery of consciousness following severe brain injuries. The model builds up from a single premise that multifocal brain injuries resulting in coma and subsequent disorders of ...

Disorders of Consciousness

2018
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 ...

Neurorehabilitation in Disorders of Consciousness

Seminars in Neurology, 2013
Survivors of severe acquired brain injury often experience prolonged disturbance in consciousness following emergence from coma. Most individuals pass through the vegetative or minimally conscious states en route to eventual recovery of consciousness, although either condition may be permanent.

Functional neuroimaging in disorders of consciousness: towards clinical implementation

Brain : a journal of neurology
Functional neuroimaging has provided several new tools for improving both the diagnosis and prognosis in patients with disorders of consciousness. These tools are now being used to detect residual and covert awareness in behaviourally non-responsive ...

Cognitive Motor Dissociation in Disorders of Consciousness

New England Journal of Medicine
BACKGROUND Patients with brain injury who are unresponsive to commands may perform cognitive tasks that are detected on functional magnetic resonance imaging (fMRI) and electroencephalography (EEG). This phenomenon, known as cognitive motor dissociation,

Behavioral Assessment of Patients with Disorders of Consciousness

Seminars in neurology, 2022
Severe brain injury is associated with a period of impaired level of consciousness that can last from days to months and results in chronic impairment.

Coma and disorders of consciousness

2013
Patients 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 ...
