Active Comparator: Total Intravenous Anesthesia with Propofol
Patients in this arm will receive general anesthesia with propofol as the primary amnestic agent.
Drug: Total intravenous anesthesia with propofol
Active Comparator: General anesthesia with Isoflurane
Patients in this arm will undergo general anesthesia with isoflurane as the primary amnestic agent.
Drug: General anesthesia with isoflurane
- Assess the correlation between perioperative change in CSF Markers of Alzheimers Disease and perioperative cognitive change. [ Time Frame: up to 6 weeks ]We will assess the magnitude of the pearson correlation coefficient for the relationship between perioperative change in CSF Markers of Alzheimers Disease and the perioperative change in the continuous cognitive index score.
- Continuous cognitive index score change [ Time Frame: 6 weeks ]
We will examine the difference in the continuous cognitive index score over time in the subjects treated with propofol versus those treated with isoflurane.
Assess the correlation between perioperative change in CSF Markers of Alzheimers Disease and perioperative cognitive change.
- Assess CSF Markers of Alzheimers Disease [ Time Frame: up to 6 weeks ]We will examine CSF Markers of Alzheimer's Disease over time in the subjects treated with propofol versus those treated with isoflurane.
- Perioperative CSF Tau/Abeta ratio change [ Time Frame: 24 hours ]We will measure the perioperative change in the CSF tau/Abeta ratio from the start of anesthesia/surgery to 24 hours later.
