Alzheimer’s disease (AD), the most prevalent form of neurodegenerative dementia, is characterized by progressive cognitive decline and neuronal loss. Despite advances in pharmacological treatments, current therapies remain limited in efficacy and often induce adverse effects. Increasing evidence highlights oxidative stress, mitochondrial dysfunction, and disrupted neurotrophic signaling as key contributors to AD pathogenesis. Pulsed electromagnetic fields (PEMFs) are emerging as a non-invasive, multifactorial approach with promising biological effects. In this study, we investigated the neuroprotective potential of PEMFs in NGF-differentiated PC12 cells exposed to hydrogen peroxide (H2O2) or amyloid-β peptide (Aβ), both of which model pathological features of AD. PEMF treatment significantly counteracted H2O2- and Aβ-induced cytotoxicity by restoring cell viability, reducing reactive oxygen species production, and improving catalase activity. Furthermore, PEMFs preserved the mitochondrial membrane potential and decreased caspase-3 activation and chromatin condensation. Mechanistically, PEMFs inhibited ERK phosphorylation and enhanced cAMP levels, CREB phosphorylation, and BDNF expression, pathways known to support neuronal survival and plasticity. In conclusion, these findings suggest that PEMFs modulate multiple stress response systems, promoting neuroprotection under oxidative and amyloidogenic conditions
