Despite advances in resting state functional magnetic resonance imaging investigations, clinicians remain with the challenge of how to implement this paradigm on an individualized basis. Here, we assessed the clinical relevance of resting state functional magnetic resonance imaging acquisitions in patients with disorders of consciousness by means of a systems-level approach. Three clinical cent...
Consciousness has two main components: wakefulness and awareness. The vegetative state is characterized by wakefulness without awareness. Recent functional neuroimaging results have shown that some parts of the cortex are still functioning in 'vegetative' patients. External stimulation, such as a painful stimulus, still activates 'primary' sensory cortices in these patients but these areas are ...
Following a coma, some patients may "awaken" without voluntary interaction or communication with the environment. More than 40 years ago this condition was coined coma vigil or apallic syndrome and later became worldwide known as "persistent vegetative state". About 10 years ago it became clear that some of these patients who failed to recover verbal or non-verbal communication did show some de...
Some brain injured patients are left in a permanent vegetative state, i.e., they have irreversibly lost their capacity for consciousness but retained some autonomic physiological functions, such as breathing unaided. Having discussed the controversial nature of the permanent vegetative state as a diagnostic category, we turn to the question of the patients' ontological status. Are the permanent...
Consciousness in experimental subjects is typically inferred from reports and other forms of voluntary behaviour. A wealth of everyday experience confirms that healthy subjects do not ordinarily behave in these ways unless they are conscious. Investigation of consciousness in vegetative state patients has been based on the search for neural evidence that such broad functional capacities are pre...
Objectives The pathological mechanism for a disorder of consciousness (DoC) is still not fully understood. Based on traditional behavioral scales, there high rate misdiagnosis subtypes DoC. We aimed to explore whether topological characterization may explain the mechanisms DoC and be effective in diagnosing Methods Using resting-state functional magnetic resonance imaging data, weighted brain n...
OBJECTIVE The number of children surviving in a persistent vegetative state is increasing with advances in medical technology. Caring for a neurologically devastated child presents unique challenges not previously described. Our objective was to gain an understanding of the pediatric nurse's experience of caring for children in a persistent vegetative state. DESIGN Qualitative phenomenologic ...
