Abstract
Radiation therapy targeting the central nervous system is widely utilized for the management of various brain tumors, significantly prolonging patient survival. Presently, investigations are assessing both clinical and preclinical applications of low-dose radiation (LDR) for the treatment of neuropathological conditions beyond tumor therapy. Special focus is given to refractory neurodegenerative diseases linked to neuroinflammation, such as Alzheimer's and Parkinson's diseases, where LDR has shown promising results. This comprehensive review examines the existing experimental data regarding the utilization of LDR in neurological disorders. It covers potential advantages in reducing neurodegenerative alterations and inflammation, as well as possible adverse effects, including neurological impairments. The review underscores the importance of the exposure protocol and the age at which LDR is administered in the context of the nervous system's pathological and physiological states, as these elements are crucial in determining LDR's therapeutic and toxic outcomes. The article concludes with a discussion on the future directions and challenges in optimizing LDR use, aiming to reduce toxicity while effectively managing neurological disorders.
