Background and Purpose: Artificial intelligence (AI) has emerged as a transformative force in modern healthcare, fundamentally reshaping diagnostics, therapeutics, drug discovery, personalised medicine and health systems management. This comprehensive review critically analyses current evidence on the application of AI technologies — including machine learning (ML), deep learning (DL), natural language processing (NLP), and computer vision — across multiple domains of human health.
Methods: A systematic narrative review was conducted across PubMed/MEDLINE, Scopus, Web of Science, IEEE Xplore, and arXiv. Peer-reviewed literature published between 2015 and 2025 was considered. Studies were selected based on methodological rigour, clinical relevance, dataset size and validation quality.
Results: AI demonstrates remarkable and increasingly validated performance in medical imaging (lung cancer CT: AUC 0.944; diabetic retinopathy: sensitivity 97.5%), clinical decision support (EHR mortality prediction: AUC 0.83–0.95), drug discovery (AlphaFold2; halicin) and mental health monitoring. Wearable AI algorithms detect atrial fibrillation at population scale. However, significant challenges persist: algorithmic bias systematically disadvantages minority populations; the majority of published AI studies lack external validation; regulatory frameworks lag technological development and clinical workflow integration remains poorly realized.
Conclusions: While AI demonstrates transformative potential in human health, realizing this potential safely and equitably requires rigorous prospective validation, bias mitigation frameworks, fit-for-purpose regulatory pathways and genuinely integrated clinical deployment. The future of AI in medicine lies in multimodal foundation models augmenting — not replacing — human clinical judgement.
