Longevity medicine is an emerging field that focuses on extending life span and improving quality of life by maintaining biological and psychological health. Ageing is a complex, multifactorial process that affects multiple systems within the human body, leading to age-related diseases and functional decline. Recent technological advances, particularly in artificial intelligence (AI), machine learning (ML), and deep learning (DL), have opened up new possibilities for understanding and intervening in the ageing process. AI-driven tools analyse large data sets to predict ageing patterns and develop personalised treatment strategies. The shift towards precision medicine allows for more accurate biomarkers of ageing, enabling earlier intervention for age-related diseases. AI applications are also transforming drug discovery processes, clinical trials, and regenerative medicine, with the ultimate goal of extending health span—the time spent in good health. Despite rapid technological advances, longevity medicine faces challenges, including regulatory barriers and the need for interdisciplinary collaboration.
