Area of Science:

Neuroscience
Metabolic Surgery
Obesity Research

Background:

Obesity is linked to cognitive decline.
Weight loss interventions are crucial for cognitive health.

Purpose of the Study:

To systematically review the impact of bariatric surgery on cognitive function.
To assess the relationship between surgically induced weight loss and cognitive performance.

Main Methods:

Comprehensive literature search across major scientific databases (MEDLINE, EMBASE, PubMed, Scopus, Web of Science, Cochrane Library).
Inclusion of 18 relevant studies from 414 identified publications.
Analysis of cognitive function using various assessment tools.

Main Results:

Most studies demonstrated cognitive improvements after bariatric surgery.
Significant and rapid weight loss correlated with enhanced cognitive function.
Improvements observed in memory, executive function, and cognitive control.

Conclusions:

Bariatric surgery is an effective intervention for improving cognitive function in individuals with obesity.
Surgically induced weight loss offers prompt and lasting cognitive benefits.
Further research can explore specific mechanisms linking weight loss and cognitive enhancement.
