Human Alzheimer and Inflammation Biomarkers after Anesthesia and Surgery

TLDR
A robust neuroinflammatory response was found in CSF biomarkers during surgery, largely because of an increase in total-tau rather than a decline in amyloid-&bgr;(1–42), which suggests that anesthetic management may make a difference in neuro inflammatory response.
Abstract
Background The prevalence of post-operative cognitive disturbance, coupled with growing in vitro, cell and animal evidence suggesting anesthetic effects on neurodegeneration, calls for further study of the interaction between surgical care and Alzheimer neuropathology. Here, we study human cerebral spinal fluid (CSF) biomarkers perioperatively.

Lasting impact of general anaesthesia on the brain: mechanisms and relevance.

TL;DR: Available mechanistic data linking general-anaesthesia exposure to impaired cognitive performance in both young and mature nervous systems are reviewed, providing a critical appraisal of the translational value of animal models.

Postoperative cognitive dysfunction: Involvement of neuroinflammation and neuronal functioning

TL;DR: The findings indicate that in young adult rats only spatial learning and memory is affected by surgery, suggesting hippocampal dependent cognition is especially vulnerable to surgery-induced impairment.

Neuroinflammation and Perioperative Neurocognitive Disorders.

TL;DR: The role of postoperative neuroinflammation and underlying mechanisms in immune-to-brain signaling after peripheral surgery are reviewed.

Post-Operative Cognitive Dysfunction: An exploration of the inflammatory hypothesis and novel therapies.

TL;DR: This review aims to describe the putative mechanisms by which surgery‐induced inflammation produces cognitive sequelae, with a focus on identifying potential novel therapies based upon their ability to modify these pathways.

Tau phosphorylation and sevoflurane anesthesia: an association to postoperative cognitive impairment.

TL;DR: It is demonstrated, in mice, that sevoflurane exposure is associated with increased tau phosphorylation through specific kinases activation and spatial memory deficits, which support a correlation between exposures to this anesthetic agent and cognitive decline.

Synaptic Activity Regulates Interstitial Fluid Amyloid-β Levels In Vivo

TL;DR: It is demonstrated that Aβ levels in the brain interstitial fluid are dynamically and directly influenced by synaptic activity on a timescale of minutes to hours, and it is suggested that synaptic activity may modulate a neurodegenerative disease process, in this case by influencing Aβ metabolism and ultimately region-specific Aβ deposition.

Endocytosis Is Required for Synaptic Activity-Dependent Release of Amyloid-β In Vivo

TL;DR: It is estimated that approximately 70% of ISF Abeta arises from endocytosis-associated mechanisms, with the vast majority of this pool also dependent on synaptic activity, which has implications for AD pathogenesis and may provide insights into therapeutic intervention.
