This paper review presents the hypothesis that ferroptosis may be a key underlying mechanism driving bipolar disorder (BD). Ferroptosis, a form of regulated cell death stemming from iron dysregulation, excessive lipid peroxidation, and failure of antioxidant defenses, is proposed to intersect with the clinical course of BD. The authors synthesize evidence from genetic studies, animal models, and clinical observations including treatment responses to anti-ferroptosis agents, thereby offering new insights that may lead to novel diagnostic biomarkers and therapeutic targets .
Score: 8 β The paper introduces ferroptosis as a novel cellular mechanism in BD, in contrast with traditional apoptotic or inflammatory models. The concept of using ferroptosis-related gene signatures as prognostic markers and the anti-ferroptosis effects observed with established BD treatments (e.g., lithium, valproate, antipsychotics) provide a fresh and innovative perspective.
Score: 7 β The review is comprehensive in its literature synthesis and interdisciplinary in approach. However, the reliance on secondary data from heterogeneous studies and the lack of new experimental results limit its overall impact. The review successfully highlights gaps in current knowledge and proposes clear directions for future research.
Score: 6 β While the hypothesis is highly relevant to BD and may spur advances in neuropsychiatry, its direct application may remain confined to this particular disorder. Broader investigations into ferroptosis in other conditions could extend its general relevance.
The review is limited by its methodological reliance on existing literature, which itself may be biased by publication, study design, and other confounding factors. Furthermore, the complex interplay between multiple cell death pathways in BD is not fully disentangled. Future studies should incorporate rigorous experimental designs and larger patient cohorts to validate the role of ferroptosis in BD .
This paper review provides a thought-provoking synthesis of existing data to propose a link between ferroptosis and bipolar disorder. Its novelty lies in shifting the focus from traditional cell death and inflammatory pathways to a mechanism centered on iron-mediated processes, though its conclusions remain largely hypothesis-driven pending further empirical validation.
