Purpose of reviewTo survey the recent medical literature examining the pathophysiology of acute brain dysfunction (delirium and coma) in the ICU. Recent findingsClinical risk factors for brain dysfunction in the ICU continue to be elucidated and prediction models developed. Multiple studies have identified sedatives, especially benzodiazepines, as modifiable risk factors for delirium. Imaging studies examining global brain disorders have demonstrated white matter lesions and brain atrophy to be… Expand
Targeting the Blood-Brain Barrier to Prevent Sepsis-Associated Cognitive Impairment
TLDR
Key insights are highlighted on the mechanisms that contribute to the BBB’s role in sepsis which include neuroinflammation, increased barrier permeability, immune cell infiltration, mitochondrial dysfunction, and a potential barrier role for tissue non-specific alkaline phosphatase (TNAP). Expand
A clinical perspective of sepsis-associated delirium
TLDR
It is expected to see further pathophysiological data and the development of novel treatments for SAD now that reliable and consistent definitions of SAD have been established. Expand
Knowns and Unknowns About Delirium in Stroke: A Review
Delirium is a transient condition characterized by sudden and fluctuating disturbances in cognitive function. The condition can be considered a sign of the brain’s vulnerability and diminishedExpand
Neuroimaging of Delirium
TLDR
Structural imaging studies suggest that delirium is associated with more brain atrophy and focal abnormalities, such as infarcts and white matter disruption, and functional imaging studies suggestion perfusion abnormalities and altered functional connectivity. Expand
Clinical neurophysiological assessment of sepsis-associated brain dysfunction: a systematic review
TLDR
There is some evidence to support EEG use in the detection and prognostication of sepsis-associated encephalopathy, but further clinical investigation is needed to confirm this suggestion. Expand
Brain atrophy and white-matter hyperintensities are not significantly associated with incidence and severity of postoperative delirium in older persons without dementia
TLDR
The present study is the first to address the potential predisposing role of brain morphologic changes toward postoperative delirium in a large prospective cohort of patients undergoing elective surgery using state-of-the-art magnetic resonance imaging (MRI) techniques conducted before admission. Expand
Quantitative proteomics of delirium cerebrospinal fluid
TLDR
The first proteomic analysis of delirium cerebrospinal fluid (CSF) reveals dysregulation of protein expression in a number of novel and unexpected clusters of proteins, in particular the granins, and provides confirmatory evidence that the inflammatory response is a component ofdelirium. Expand
Disorders of Consciousness in Systemic Diseases
Alteration of consciousness is the most common neurologic manifestation of systemic disease. Consciousness is composed of two general components: arousal and content. Depending on the anatomicExpand
Delirium in elderly people
TLDR
In view of the complex multifactorial causes of delirium, multicomponent non-pharmacological risk factor approaches are the most effective strategy for prevention and no convincing evidence shows that pharmacological prevention or treatment is effective. Expand
Search Strategy and Selection Criteria
Delirium, an acute disorder of attention and cognition, is a common, serious, costly, underrecognized and often fatal condition for seniors. Its diagnosis requires a formal cognitive assessment andExpand

Statins and brain dysfunction: a hypothesis to reduce the burden of cognitive impairment in patients who are critically ill.
TLDR
It is hypothesized that the known pleiotropic effects of statins may redirect microglial activation and promote an antiinflammatory phenotype, thereby offering the potential to reduce the public health burden of delirium and its associated long-term cognitive injury. Expand
The neuroinflammatory hypothesis of delirium
TLDR
The neuroinflammatory hypothesis of delirium is explored based on recent evidence derived from animal and human studies and shows compelling evidence that acute peripheral inflammatory stimulation induces activation of brain parenchymal cells, expression of proinflammatory cytokines and inflammatory mediators in the central nervous system. Expand
Hypothesis for the pathophysiology of delirium: role of baseline brain network connectivity and changes in inhibitory tone.
  • R. Sanders
  • Psychology, Medicine
  • Medical hypotheses
  • 2011
TLDR
This theory accounts for the various forms of delirium, hypoactive, hyperactive and mixed, which will depend upon how and which networks breakdown and the degree change in inhibitory tone produced. Expand
Is there a final common neural pathway in delirium? Focus on acetylcholine and dopamine.

TLDR
Electroconvulsive therapy is described as a special situation in which excess dopamine and Delirium may have a therapeutic effect on depression recovery, in contrast with the usual association of delirium with negative effects. Expand
Is there a final common neural pathway in delirium? Focus on acetylcholine and dopamine.
This article reviews the literature relevant to improving our understanding of the neural underpinnings of delirium. That the characteristic symptoms of delirium occur as a result of a wide diversityExpand
The association of the kynurenine pathway of tryptophan metabolism with acute brain dysfunction during critical illness*
TLDR
Increased kynurenine pathway activation was associated with fewer days alive and without acute brain dysfunction in intensive care unit patients and future studies are warranted to clarify this relationship and investigate potential therapeutic interventions. Expand
Cholinergic deficiency hypothesis in delirium: a synthesis of current evidence.
TLDR
Current understanding of the cholinergic deficiency hypothesis in delirium is examined by synthesizing evidence on potential pathophysiological pathways, which may yield innovative approaches in the diagnosis, prevention, and treatment of this common, costly, and morbid condition. Expand
Science review: The brain in sepsis – culprit and victim
TLDR
The current review aimed at summarizing the current knowledge about the reciprocal interaction between the immune and central nervous systems during sepsis by taking part in circumventricular organs that, being free from blood-brain-barrier, interface between brain and bloodstream, in autonomic nuclei including the vagus nerve, and finally through the damaged endothelium. Expand
Cerebral perfusion in sepsis-associated delirium
TLDR
In this small group of patients, cerebral perfusion assessed with transcranial Doppler and near-infrared spectroscopy did not differ between patients with and without sepsis-associated delirium, however, the state of autoregulation differed between the two groups. Expand
Serotonin and amino acids: partners in delirium pathophysiology?
TLDR
It will require further study to determine the complex influence of the stress response and immune activation on plasma amino acids, neurotransmitter function and the development of delirium, especially in the more vulnerable older patients. Expand
