The rapid growth of lithium (Li)-related industrial activities and the application of Li-containing products have become an emerging human health concern. Li has been employed to treat human mental disorders
however, excessive Li salt accumulation can lead to brain damage. The mechanism of toxicity of long-term exposure to Li in the brain warrants further investigation. This research study established a network toxicology strategy to evaluate the molecular mechanisms and putative toxicity of lithium chloride (LiCl). The analysis of online databases identified 80 intersection targets for LiCl-induced neurotoxicity. Further refinements via STRING and Cytoscape software highlight 10 core targets. Furthermore, phosphatidylinositol 3 kinase/protein kinase B (PI3K/AKT), apoptosis pathways, and mitogen-activated protein kinase (MAPK) were enriched. Molecular docking validated the robust interaction of core targets with Li
