INTRODUCTION

The rapid increase in global life expectancy has brought geriatric disorders to the forefront of public health challenges. Conditions such as Alzheimer’s disease, Parkinson’s disease, cardiovascular disorders, osteoporosis, and various cancers significantly contribute to healthcare burdens and reduce the quality of life among the aging population [1]. These multifactorial diseases often involve complex comorbidities, necessitating precise diagnostic and therapeutic strategies for effective management.

Nuclear medicine, powered by cyclotron technology, has emerged as a transformative tool for addressing these challenges. Cyclotrons enable the production of short-lived, high-energy radioisotopes essential for advanced imaging and targeted therapy. Isotopes such as Fluorine-18, Lutetium-177, and Carbon-11 have revolutionized the ability to diagnose diseases early, monitor their progression, and deliver precise therapeutic interventions [2].

For example, in Alzheimer’s disease, imaging with Fluorine-18-labeled amyloid and tau tracers allows for the detection of pathological changes years before clinical symptoms appear, offering a critical window for early intervention. Similarly, diagnostics for Parkinson’s disease benefit from tracers like [¹¹C] DTBZ, which facilitate accurate differential diagnoses and support tailored treatment approaches [3].

The short half-life of many isotopes necessitates on-site production facilities or efficient logistics for timely distribution. Additionally, the high costs associated with cyclotron installation, operation, and maintenance limit widespread accessibility, particularly in resource-constrained settings [5]. Compact cyclotrons and automated synthesis modules could help address these challenges by decentralizing isotope production and lowering operational barriers. Innovations in artificial intelligence (AI) are also enhancing imaging analysis, facilitating personalized treatment planning, and improving workflow efficiencies [6].

The application of cyclotron technology underscores the importance of interdisciplinary research to further advance the field. Developing novel radioisotopes, enhancing radiopharmaceutical synthesis, and integrating hybrid imaging modalities are critical to meeting the evolving demands of geriatric healthcare. Equitable access remains a pressing concern, as underserved regions face significant barriers to adopting these advancements. Expanding infrastructure and implementing training programs will be pivotal in ensuring the benefits of nuclear medicine reach all populations.

This article examines the role of cyclotron technology in advancing the management of geriatric disorders. It explores current applications, emerging innovations, and future directions to overcome existing challenges, fostering a paradigm shift in the care of age-related diseases. By leveraging cyclotron-driven progress, nuclear medicine offers a path to improved diagnostics and therapies, ultimately enhancing the well-being of the elderly population.
