|
Previous work in animal models suggests that inhalational anesthetic agents may accelerate
Alzheimer's disease pathogenesis, but it is unclear to what extent this may happen in
humans. Here, the investigators propose to measure Alzheimer's disease-related neural
markers in the cerebrospinal fluid (CSF) of patients exposed to anesthesia while undergoing
neurosurgical procedures that require lumbar drain placement. Patients will be randomized to
either receive inhalation anesthesia with isoflurane or intravenous anesthesia with
propofol.
CSF and blood samples will each be collected at the induction of anesthesia, and then again
three hours later. CSF samples will be assayed for amyloid beta, tau, and other Alzheimer's
disease-associated markers; blood samples will be assayed for serum inflammatory markers and
used for genotyping studies. These studies should clarify the effect of common anesthetic
agents on Alzheimer's disease related neural markers.
