Background: There is a correlation between gut microbiota and cognitive function. The mechanisms and pathways explain why the incidence of Alzheimer's disease in subjects undergoing bariatric surgery is lower than in other people with obesity.
Methods: In this review article, we aim to discuss the association of obesity, cognitive impairment, and physiological changes after bariatric surgery.
Results: Bariatric surgery has a series of physiological benefits which may lead to an improvement in cognitive functions in individuals who are prone to later developing Alzheimer's disease. Also, taxonomical change in the gut microbiome profile provides a healthy condition for living with better levels of cognition without neuropathological damages in older ages.
Conclusion: It can be concluded that there is a possible correlation between cognitive dysfunction and increased risk of cognitive dysfunction in people with a BMI higher than 40 kg/m. Bariatric surgery may increase neurotransmitters and improve the gut bacteria, leading to a significant reduction in the risk of Alzheimer's disease.

Reliable and sensitive testing of physical function is crucial for assessing the effects of treatment or exercise intervention in various patient populations. The present study investigated the test-retest reliability and sensitivity (smallest detectable difference: SDD) of selected physical performance tests commonly used in clinical rehabilitation, including tests of habitual and maximal walking speed, walking endurance capacity, handgrip strength (HGS), and lower limb muscle power (Sit-to-Stand (STS), stair climb) in adults with severe obesity meeting the criteria for bariatric surgery. Thirty-two adults (BMI 43.

Background: Although bariatric surgery is the most effective obesity treatment, few nationwide cohort studies have evaluated its safety. This study aimed to evaluate surgical trends after insurance coverage implementation and analyze the surgical outcomes of bariatric surgery.
Methods: A retrospective analysis of bariatric surgery in patients with obesity was conducted using data from Korean National Health Insurance System (NHIS) claims.

Purpose Of Review: Eating behaviour-focused interventions are essential for improving health and weight-related outcomes in patients undergoing metabolic bariatric surgery (MBS). This work aims to examine the content of eating behaviour-focused weight management interventions adjunct to MBS in terms of the type and quantity of behaviour change techniques (BCTs). A literature search retrieved randomised controlled and parallel group trials up to March 2024.

Purpose Of Review: To highlight recent research on antidepressant use and weight change and explore best clinical practices for reducing weight gain and obesity risk in individuals with depression.
Recent Findings: Research on antidepressant use and weight gain suggests that genetic and biological factors including metabolizer phenotypes and inflammation can help to predict an individual's threshold for weight change among specific agents. For individuals with increased susceptibility to metabolic complications, medications including bupropion, fluoxetine, and newer agents (e.
