Preoperative cognitive intervention reduces cognitive dysfunction in elderly patients after gastrointestinal surgery:...

Area of Science:

• Geriatric Medicine
• Neuroscience
• Surgical Outcomes

Background:

• Preoperative factors significantly influence postoperative cognitive dysfunction (POCD) in elderly individuals.
• Elderly patients undergoing surgery are at high risk for cognitive decline.
• The role of preoperative interventions in mitigating POCD requires further investigation.

Purpose of the Study:

• To evaluate the efficacy of preoperative cognitive training in reducing POCD incidence.
• To determine if mnemonic skill training impacts early postoperative cognitive function.
• To identify risk factors associated with POCD development.

Main Methods:

• 141 elderly patients undergoing gastrointestinal surgery were randomized into intervention (cognitive training) and control groups.
• The intervention group received three 1-hour sessions of mnemonic skill training using the method of loci (MoL).
• Neuropsychological battery tests (NPTs) assessed cognitive function preoperatively and one week postoperatively.

Main Results:

• POCD incidence was significantly lower in the cognitive training group (15.9%) compared to controls (36.1%).
• Cognitive training improved performance on visuospatial memory and symbol-digit modalities tests.
• Advanced age, prolonged anesthesia/surgery, and lack of cognitive training were linked to higher POCD risk.

Conclusions:

• Mnemonic skill-based cognitive training effectively reduces early postoperative cognitive decline in elderly surgical patients.
• The method of loci (MoL) is a viable strategy for preoperative cognitive enhancement.
• Targeted cognitive interventions can improve surgical outcomes in geriatric populations.
