Electrophysiological correlates of behavioural changes in vigilance in vegetative state and minimally conscious state.
The existence of normal sleep in patients in a vegetative state is still a matter of debate. Previous electrophysiological sleep studies in patients with disorders of consciousness did not differentiate patients in a vegetative state from patients in a minimally conscious state. Using high-density electroencephalographic sleep recordings, 11 patients with disorders of consciousness (six in a mi...
متن کاملFunctional Evaluation of Awareness in Vegetative and Minimally Conscious State
OBJECTIVE The aim of this study was to assess differences in brain activation in a large sample of Vegetative State (VS) and Minimally Conscious State (MCS) patients, using functional magnetic resonance imaging (fMRI). METHODS We studied 50 patients four to seven months after brain injury. By using international clinical criteria and validated behavioural scales such as the Glasgow Coma Scale...
متن کاملNeuroimaging and Outcome Assessment in Vegetative and Minimally Conscious State
Consciousness is a multifaceted concept that has two dimensions: arousal, or wakefulness (i.e., level of consciousness), and awareness (i.e., content of consciousness) (Laureys et al., 2004). An accurate and reliable assessment of the arousal and awareness of consciousness in patients with severe brain damage is of greatest importance for the differential diagnosis of low levels consciousness p...
متن کاملHow can we know if patients in coma, vegetative state or minimally conscious state are conscious?
This paper examines the claim that patients in coma, vegetative state and minimally conscious state may in fact be conscious. The topic is of great importance for a number of reasons--not least ethical. As soon as we know a given creature has any experiences at all, our ethical attitude towards it changes completely. A number of recent experiments looking for signs of intact or partially intact...
متن کاملCerebral Function in Coma, Vegetative State, Minimally Conscious State, Locked-in Syndrome, and Brain Death
Progress in intensive care has increased the number of patients who survive severe acute brain injury. The majority of these patients recover from their coma within the first days after the insult, others will take more time and go through different stages before fully or partially recovering awareness (e.g., minimally conscious state, vegetative state) or will permanently lose all brain functi...
