Insight into Bariatric Surgery and Brain Health

Advertisment

A recent study has shed light on the potential positive effects of bariatric surgery on the brain. According to the research, individuals who underwent bariatric surgery experienced improvements in specific brain functions, notably in areas related to memory and executive function. The weight loss and metabolic changes resulting from the surgery are believed to play a significant role in these cognitive enhancements. However, further investigation is required to fully understand the relationship between bariatric surgery and brain health.

Plasma Metabolic Profiles and Cognitive Performance

The study assessed the effects of bariatric surgery on plasma metabolic profiles and cognitive performance in 26 women. Post-surgery, the women displayed an improvement in attention capacity and executive function, although immediate memory seemed to have deteriorated. The metabolic profile showed a decrease in beta-tocopherol and an increase in serine, glutamic acid, butanoic acid, and glycolic acid. Cluster analysis identified two groups, with one showing improved attention and executive function but reduced performance in the immediate memory test. Serine, glutamic acid, and glycolic acid were identified as potential metabolites linked to the alteration of cognitive performance.

Long-term Cognitive Improvement and Brain Health

Recent research suggests that bariatric surgery may contribute to long-term enhancements in cognition and brain structure, as well as provide additional health benefits such as weight loss and improved physical activity levels. Approximately two in five participants experienced a >20% improvement in global cognitive function 24 months post-surgery. The potential link between bariatric surgery and dementia is also explored, with implications that the surgery might have protective effects against dementia. However, the study's limitations, such as the absence of a control group and unequal sex distribution among participants, should be considered. Updated guidelines for weight-loss surgery have been issued in light of the findings, expanding eligibility to more individuals.

Bariatric Surgery and Lasting Health Benefits

A study published in JAMA Network Open highlights the significant improvements in cognitive function and alterations in brain parameters at 6 and 24 months post-surgery. The study participants, 80% of whom were women, exhibited lasting health benefits, with some seeing improvements as much as two years following surgery. Participants experienced improvements in global cognition, ability to shift attention, episodic memory, verbal fluency, and working memory. Brain imaging revealed changes in gray matter volume, cortical thickness, and cerebral blood flow, suggesting that weight loss from bariatric surgery could lead to significant structural changes in the brain. The study also highlighted the potential of bariatric surgery to alleviate depressive symptoms and encourage higher physical activity levels.

Impact of Bariatric Surgery on Brain Function

Another study aimed to understand the impact of bariatric surgery on brain function. The study included 133 participants who underwent the surgery and found that sustained cognitive improvement is likely a result of lower inflammation, remission of comorbidities, higher physical activity, and better mood. The study showed that mean body weight, BMI, WC, and blood pressure were significantly lower at 6 and 24 months after surgery. Several cognitive domains, including working memory, episodic memory, verbal fluency, and global cognition, improved at 6 and 24 months after surgery. Brain changes were observed after surgery, with gray matter volume, cortical thickness, and cerebral blood flow all significantly lower after 24 months. The study also found that after 6 months, levels of various biomarkers were noticeably lower, whereas adiponectin and neurofilament light chain were significantly higher compared with baseline levels.

Conclusion

The potential cognitive benefits of bariatric surgery are promising, and further research could provide avenues for preventive measures against cognitive decline and dementia. However, it is essential to consider the study's limitations and the individual's health condition and needs before opting for bariatric surgery.
