- Older adults are at increased risk of postoperative cognitive complications.
- Preoperative psychological factors like depression, anxiety, personality traits, and stress-related factors may impact cognitive outcomes.
- A systematic review and meta-analysis included 30 studies with 6714 subjects.
- Postoperative delirium was the most reported outcome, with incidence ranging from 9% to 55.6%.
- Depression was the most consistently reported psychological risk factor for postoperative delirium.
- Evidence for anxiety, personality traits, and stress as risk factors is limited.
- Multidimensional, standardized cognitive assessments are needed for better evaluation.
- Future studies should focus on interventions to reduce risk and improve cognitive outcomes.
