One hundred and forty episodes in 112 patients (58 boys) with diabetic ketoacidosis (96 episodes) and diabetic ketosis (44 episodes) were studied to elucidate the clinical and laboratory risk factors for altered level of consciousness at presentation and to analyze the outcome of a distinct protocol in the treatment of diabetic ketoacidosis. The patients were analyzed according to demographic d...

The study of pathological impairments of consciousness, as they can appear in severely brain injured patients, can be particularly useful to better clarify cognitive processes and cerebral substrates which underlie consciousness. In this review, we will introduce the disorders of consciousness that can be presented by severely brain-injured patients and the behavioural scales that can be used t...

BACKGROUND Mechanisms of anesthesia-induced loss of consciousness remain poorly understood. Resting-state functional magnetic resonance imaging allows investigating whole-brain connectivity changes during pharmacological modulation of the level of consciousness. METHODS Low-frequency spontaneous blood oxygen level-dependent fluctuations were measured in 19 healthy volunteers during wakefulnes...

One challenging aspect of the clinical assessment of brain-injured, unresponsive patients is the lack of an objective measure of consciousness that is independent of the subject's ability to interact with the external environment. Theoretical considerations suggest that consciousness depends on the brain's ability to support complex activity patterns that are, at once, distributed among interac...

Previous studies revealed that transient hyperammonemia was noted after generalized convulsion. This study was undertaken to analyze the association between postictal state and serum ammonia levels. Adult patients presenting to the emergency department with seizures were included. Serum ammonia and other blood tests were compared between patients with full recovery of consciousness after genera...

Recently, a welcome trend has emerged - in addition to the traditional studies on contents and states of consciousness, levels of consciousness have become a matter of research. However, there are some conceptual and methodological difficulties with this research - the labels used for empirical measurement of levels are ambiguous and underspecified while the research on neural correlates of con...

Consciousness and emotion feature prominently in our personal lives, yet remain enigmatic. Recent advances prompt further distinctions that should provide more experimental traction: we argue that emotion consists of an emotion state (functional aspects including emotional response) as well as feelings (the conscious experience of the emotion); and that consciousness consists of level (e.g., co...

We propose a new approach to the neuroscience of consciousness, growing out of the 'enactive' viewpoint in cognitive science. This approach aims to map the neural substrates of consciousness at the level of large-scale, emergent and transient dynamical patterns of brain activity (rather than at the level of particular circuits or classes of neurons), and it suggests that the processes crucial f...

background and objective: different personality aspects including identity styles, self-efficacy, and cognitive abilities can play a certain role in successful learning result in high educational success. we assessed the value of identity styles, self-efficacy and metacognition beliefs for predicting the level of educational success in female high-school students. methods: in a cross-sectional ...
