Postoperative Cognitive Dysfunction Involved With AMPK and Inflammatory Mediators

Neuronal apoptosis resulting from post-surgery inflammation, phosphorylation of tau protein and accumulation of amyloid is associated with postoperative cognitive dysfunction.

Neuronal apoptosis resulting from post-surgery inflammation, phosphorylation of tau protein and accumulation of amyloid is associated with postoperative cognitive dysfunction. Adenosine monophosphate-activated protein kinase (AMPK) can be involved in anti-inflammation, neuronal repair and anti-inflammation of the body through different downstream proteins and pathways.

In addition, the activation of AMPK regulates tau protein phosphorylation and reduces amyloidogenesis in neurons. Yanlin Bi and co-workers from the Affiliated Qianfoshan Hospital of Shandong University in China found that inflammatory cytokines and AMPK changed remarkably in the hippocampus of postoperative cognitive dysfunction rats.

Aspartic Acid: A Biomarker for Postoperative Cognitive Dysfunction
Postoperative cognitive dysfunction is the deterioration of cognitive performance after anesthesia and surgery.

Therefore, the involvement of AMPK and inflammatory factors in postoperative cognitive dysfunction is considered to be an accommodation to postoperative cognitive dysfunction. The relevant study has been published in the Neural Regeneration Research

Research Sheds Light on Postoperative Cognitive Dysfunction
Previous research has shown that older persons tend to suffer from memory lapses and other types of cognitive impairment after undergoing surgical procedures.
