Neurodegenerative diseases (NDDs), including Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, and hereditary ataxias, remain major global health challenges with limited therapeutic options. Although clinically and genetically diverse, these diseases share extensively studied cellular and molecular hallmarks, including protein aggregation, impaired proteostasis, cytoskeletal abnormalities, altered energy metabolism, nucleic acid damage, and chronic inflammation. Emerging evidence indicates that dysfunction of the centrosome-cilium-satellite axis intersects with these established pathways in disease- and cell type-specific contexts. This axis, composed of centrosomes, primary cilia, and centriolar satellites, coordinates cytoskeletal organization, ciliary signaling, trafficking, proteostasis, and stress responses and acquires specialized functions in neurons that support polarity, connectivity, and long-term maintenance. In this review, we outline the structure, function, and neuronal specializations of the centrosome-cilium-satellite axis, then examine how its dysfunction has been reported in neurodegenerative disease models. We also discuss centriolar satellites as regulators of centrosome and cilium biology whose disease-specific roles in classical NDDs remain comparatively underexplored, with insights from Huntington's disease and schizophrenia. Finally, we discuss therapeutic strategies aimed at restoring axis structure and dynamics, modulating ciliary signaling, and correcting disease-linked genetic or transcript-level defects, emphasizing mechanism-based approaches that require validation in disease-relevant models. Together, the centrosome-cilium-satellite axis provides an emerging framework for understanding context-dependent organelle dysfunction in neuronal vulnerability and neurodegeneration.
