Neurodegeneration is intrinsically linked to aging through processes such as oxidative stress, mitochondrial dysfunction, and chronic inflammation. Nuclear factor erythroid 2-related factor 2 (Nrf2) emerges as a central transcription factor regulating these molecular events and promoting cytoprotective responses. In neurodegenerative diseases, notably, frontotemporal dementia (FTD) and Parkinson's disease (PD), genetic mutations-including MAPT, LRRK2, PINK1, PRKN, and SNCA-have been reported to alter Nrf2 signaling, both in vitro and in vivo. Melatonin, a neurohormone widely known for its strong antioxidant and mitochondria-stabilizing properties, has been shown to activate Nrf2 and restore redox balance in several experimental models of neurodegeneration. Its effects include a reduction in tau hyperphosphorylation, α-synuclein aggregation, and neuroinflammation. While most data are derived from sporadic models of Alzheimer's disease and PD, emerging evidence supports a role for melatonin in familial forms of FTD and PD as well. Thus, targeting Nrf2 through melatonin may offer a promising approach to mitigating neurodegeneration, especially in the context of mutation-driven pathologies. Further investigation is warranted to explore mutation-specific responses and optimize the therapeutic strategies.
