Purpose of review: To provide up to date information on postoperative delirium and neurocognitive disorders in surgical cancer patients.
Recent findings: Established risk factors such as age, psychosocial factors, comorbidities, frailty and preexisting cognitive decline continue to exhibit associations with perioperative neurocognitive disorders (PND); novel risk factors identified recently include microbiome composition and vitamin D deficiency. Prevention measures include cognitive prehabilitation, perioperative geriatric assessment and multidisciplinary care, dexmedetomidine and multimodal analgesic techniques. Studies investigating ciprofol, remimazolam, esketamine, ramelteon and suvorexant have shown encouraging results. Controversy remains regarding the use of inhalational versus intravenous general anesthesia. Innovative approaches to address PND are a rapidly developing area of research, but more studies are needed to identify effective prevention and management interventions. Despite challenges and controversy in the field, implementation of best practice can reduce the detrimental impact of PND on patients, caregivers, and society at large.
