Postoperative cerebral dysfunction in the elderly: Diagnosis and prophylaxis.

Area of Science:

• Geriatric Medicine
• Neuroscience
• Surgical Complications

Background:

• Post-operative cerebral dysfunction encompasses delirium and cognitive disorders, frequently impacting patients over 75.
• These conditions share similar pathophysiology linked to neuro-inflammation, independent of surgical complications.

Observation:

• Delirium is typically early and reversible, while cognitive disorders are later and prolonged.
• Reduced pre-operative cognitive status is a significant risk factor for post-operative cerebral dysfunction.

Findings:

• No single preventive measure is definitively effective; a multifactorial approach is recommended.
• Enhanced post-operative recovery programs integrating various minor measures show promise.

Implications:

• Pre-operative rehabilitation, including nutritional, physical, and cognitive support, can mitigate risks.
• Managing neuro-inflammation is key, though direct preventive strategies require further study.
