AI contribution statement: AI tools (DeepL and DeepSeek) were used solely for linguistic refinement and formatting assistance. The study design, methodology, data analysis, and interpretation of results were conducted solely by the human authors. AI tools played no role in these intellectual and scientific aspects of the research. Only Figure 4 was created using the AI-powered design tool “nano Banana” to generate medical/biological vector illustration elements in a style consistent with platforms like Figdraw and BioRender. All other figures and images in the manuscript are original creations produced by the authors without AI assistance.
Conflict-of-interest statement: The authors declare that they have no competing interests.

Core Tip
Core Tip: Post-stroke depression risk is refined by emerging biomarkers like vitamin D deficiency, hyperhomocysteinemia, and insulin resistance, alongside traditional factors. Multi-omics and artificial intelligence-driven models integrating clinical, neuroimaging, and inflammatory data show high predictive potential for precision stratification. Mechanistically, microglial/astrocytic polarization-driven neuroinflammation and gut-brain axis dysregulation are key therapeutic targets. Beyond first-line selective serotonin reuptake inhibitors, agomelatine, vitamin D supplementation, anti-inflammatory strategies, and evidence-based traditional Chinese medicine formulations that modulate neuro-immune crosstalk offer promising adjunctive treatments. A “predict-mechanism-intervene” paradigm is advocated to translate these advances into personalized management and improve long-term outcomes.
