Semaglutide's Role in Modulating the Brain-Heart Axis: Implications for Obesity and Alzheimer’s Disease Co-management
Bibliographic record
Abstract
Purpose: This study aimed to investigate the potential of Semaglutide, a GLP-1 receptor agonist, in modulating the brain-heart axis and offering a dual-therapeutic benefit for patients with comorbid obesity and Alzheimer’s disease. Methodology: A comprehensive review of recent clinical trials, experimental studies, and mechanistic analyses published between 2020 and 2025 was conducted using data sourced from PubMed, Scopus, and Embase. The inclusion criteria focused on studies exploring Semaglutide's effects on neuroinflammation, cardiovascular function, cognition, and metabolic parameters. Both qualitative synthesis and quantitative meta-analyses were applied. Additional data visualization techniques were employed to present key findings through tables, charts, and pathway diagrams. Findings: The analysis revealed that Semaglutide reduced key pro-inflammatory biomarkers (e.g., IL-6, TNF-α), improved heart rate variability, and showed neuroprotective effects by enhancing cerebral blood flow and preserving cognitive function in early-stage AD patients. Clinically, Semaglutide led to substantial weight loss, improved glycemic control, and favorable cardiovascular outcomes. Meta-analytic data showed statistically significant improvements in cognitive assessments (MMSE and MoCA scores) and cardiometabolic markers in dual-diagnosis patients, indicating the agent’s cross-system therapeutic relevance. Unique Contribution to Theory, Policy, and Practice: This study provides a novel framework for understanding the role of GLP-1 receptor agonists in modulating the brain-heart axis and managing dual-pathology in metabolic and neurodegenerative diseases. It offers translational insights for clinicians seeking integrated treatment strategies and emphasizes the importance of repositioning Semaglutide as a potential therapeutic candidate beyond diabetes and obesity, particularly in neurocardiometabolic comorbidity management. Future policy and clinical trials should focus on long-term safety, patient stratification, and the incorporation of brain-heart biomarkers into therapeutic decision-making.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
