✓ Peer-reviewed alzhub usefulness score 44 out of 100. Tau biomarkers

Topic: Amyloid, tau and blood-test diagnosis

Background The prevalence of postoperative cognitive disturbance, coupled with growing in vitro, cell, and animal evidence suggesting anesthetic effects on neurodegeneration, calls for additional study of the interaction between surgical care and Alzheimer neuropathology. The authors studied human cerebrospinal fluid (CSF) biomarkers during surgery. Methods Eleven patients undergoing idiopathic nasal CSF leak correction were admitted to this Institutional Review Board-approved study.

Key findings

Why it matters

This study measured cerebrospinal fluid biomarkers in only 11 patients undergoing surgery for nasal CSF leak, to look at whether anesthesia and surgery affect Alzheimer-related markers. The sample is very small and preliminary, and no treatment, cure, or prevention is shown.
