Use of prolonged fasting
Maintenance of optimal depth of anesthesia (BIS 40–60)
Sedative premedication for all patients

True
False

POCD is best described as:
A temporary decline in liver function after surgery
A progressive and irreversible decline in cognitive function post-surgery
Subtle impairments in memory, concentration, and information processing after surgery
Acute confusion due to medication toxicity
What is the main role of brain-derived neurotrophic factor (BDNF) in POCD pathophysiology?
Supports neuronal growth and synaptic plasticity
Induces neuronal apoptosis
Increases the activity of mitochondrial complex IV
Promotes tau protein phosphorylation
Which group is most likely to benefit from preoperative cognitive screening?
Paediatric patients
Young athletes undergoing minor procedures
Older adults with multiple comorbidities
Individuals with acute trauma
Which phase of perioperative management demands the greatest multidisciplinary involvement for POCD risk reduction?
Preoperative phase
Intraoperative phase
Postoperative phase
All phases require multidisciplinary involvement
Select the incorrect statement regarding POCD prevention:
Avoidance of deep anesthesia and hypoxia
Balanced anesthesia technique and use of short-acting opioids
Minimize pain and discomfort postoperatively
No need for preoperative counseling on cognitive risk
