Neurophysiological Indicators of Residual Cognitive Capacity in the Minimally Conscious State
BACKGROUND The diagnostic usefulness of electrophysiological methods in assessing disorders of consciousness (DoC) remains to be established on an individual patient level, and there is need to determine what constitutes robust experimental paradigm to elicit electrophysiological indices of covert cognitive capacity. OBJECTIVES Two tasks encompassing active and passive conditions were explore...
متن کاملResidual cognitive function in comatose, vegetative and minimally conscious states.
PURPOSE OF REVIEW The clinical evaluation of cognition in non-communicative severely brain-damaged patients is inherently difficult. In addition to novel behavioural 'consciousness-scales', the role of para-clinical markers of consciousness, such as event related potentials and functional neuroimaging is reviewed. RECENT FINDINGS New behavioural scales for vegetative and minimally conscious p...
متن کاملEmotion processing in the minimally conscious state.
As a newly described condition distinct from coma or the vegetative state, minimally conscious state (MCS) is characterised by a threshold level of consciousness, and diagnostic criteria have recently been proposed. 1 In MCS, cognitively mediated behaviour occurs inconsistently, but is reproducible or sustained enough to be differentiated from reflexive behaviour. It is clinically essential to ...
متن کاملCerebral processing in the minimally conscious state.
We studied a patient in a minimally conscious state using PET and cognitive evoked potentials. Cerebral metabolism was below half of normal values. Auditory stimuli with emotional valence (infant cries and the patient's own name) induced a much more widespread activation than did meaningless noise; the activation pattern was comparable with that previously obtained in controls. Cognitive potent...
متن کاملClinical differentiation and outcome evaluation in vegetative and minimally conscious state patients:the neurophysiological approach.
The neurophysiological approach to patients with disorders of consciousness allows recording of both central and peripheral nervous system electrical activities and provides a functional assessment. Data obtained using this approach can supplement information from clinical neurological examination, but also from the use of morphological neuroimaging techniques: computed tomography and magnetic ...
