ABSTRACT

There is a complex pathological association between neurodegenerative diseases and cancer. The epidemiological negative correlation between Parkinson's disease (PD) and brain tumor is particularly noteworthy. PD is characterized by the loss of dopaminergic neurons and the formation of Lewy bodies, while glioma, the representative of brain tumors, originates from the malignant transformation of glial cells. The molecular interaction network between these two diseases is elusive, limiting the development of cross‐disease treatment strategies. This review systematically summarizes the associations between PD and glioma in genetic predispositions, epigenetic modifications, alterations in subcellular compartments, and cellular mechanisms concerning neurons, glial cells, and stem cells. Additional links arise from circadian rhythm regulation, oxidative stress, and gut microbiota, underscoring the importance of systemic pathways that connect neurodegeneration and tumorigenesis. Within this context, cancer neuroscience emerges as a critical framework, demonstrating how neuronal activity drives cancer progression by shaping the tumor microenvironment. Therapeutic opportunities build upon these mechanistic insights, including engineering neuron types to suppress cancer growth, modulating synaptic genes, inducing neuronal cell death cascades, and controlling inflammation to disrupt tumor‐nerve crosstalk. Emerging neuroscience‐inspired technologies may drastically expand the treatment landscape. This review tries to unveil a potential theoretical paradigm for developing precise therapies with both neuroprotection and antitumor effects.
