The effective treatment of neurodegenerative diseases (NDDs), such as Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis, remains a critical challenge in modern medicine. Given the limitations of current therapies, alternative strategies to slow neurodegeneration are urgently needed. This study presents a critical review of the current evidence regarding low-dose ionizing radiation (LDIR) as a promising modality for modulating neurodegenerative processes. This study examines current experimental data on the effects of LDIR on cellular protective and compensatory mechanisms, including evidence from in vivo models of NDDs. Our analysis demonstrates that LDIR enhances antioxidant activity and DNA repair, stimulates autophagy and neuroplasticity, and modulates neuroinflammatory signaling. Collectively, these findings support the hypothesis of the neuroprotective potential of LDIR, underscoring its translational viability provided that strict dosimetric guidelines are followed and individual biological responses are rigorously monitored.
