Summary
Bariatric surgery shows lasting cognitive benefits. Key areas like attention, executive function, and memory remain improved up to three years post-operation, suggesting sustained cognitive enhancement.
Area of Science:
- Neuroscience
- Metabolic Surgery
- Cognitive Function
Background:
- Bariatric surgery is linked to cognitive enhancements.
- Investigating long-term cognitive effects of bariatric surgery is crucial.
- This study aimed to confirm sustained cognitive improvements at 3 years post-surgery.
Purpose of the Study:
- To test the hypothesis that cognitive improvements persist 3 years after bariatric surgery.
- To evaluate the long-term impact of bariatric surgery on cognitive domains.
Main Methods:
- Fifty patients undergoing bariatric surgery were assessed.
- Cognitive function was evaluated using a computerized test battery.
- Assessments were conducted at 12 weeks, 12, 24, and 36 months post-surgery.
Main Results:
- Significant improvements were observed in attention, executive function, and memory.
- Attention peaked at 24 months, with sustained average levels at 36 months.
- Executive function improvements peaked at 36 months, and memory improvements were maintained.
Conclusions:
- Bariatric surgery appears to promote enduring cognitive enhancements.
- Further long-term studies (e.g., 10 years) are warranted.
- Bariatric surgery may help mitigate cognitive decline in individuals with severe obesity.
