Ferroptosis is a newly characterised form of programmed cell death. This cell death is associated with the pathogenesis of a variety of neurodegenerative diseases, making it a potential therapeutic target for such diseases. In this review, we focus on the interplay between CFS and ferroptosis. Relevant domestic and international literature is reviewed to summarise available findings, elucidate molecular regulatory mechanisms, and identify promising directions for future research. Our analysis reveals a bidirectional interaction between CFS and ferroptosis. Ferroptosis may contribute to CFS through oxidative stress and neuroinflammation, whereas pathological changes associated with CFS could further exacerbate ferroptosis. This review first describes the function of ferroptosis in CFS pathogenesis. Targeting ferroptosis-related pathways may offer a potential therapeutic strategy for CFS.

The epidemiology of MS reflects a complex interplay between genetic susceptibility, including specific HLA alleles, and environmental factors such as geographic location, vitamin D status, and Epstein-Barr virus infection. MS is more common in women, who more frequently develop relapsing-remitting disease, whereas primary progressive MS is relatively more common in men. Disruption of the blood-brain barrier facilitates immune-cell infiltration and promotes neuroinflammation. The innate immune response involves macrophages, microglia, and other cell types that contribute to inflammation and neuronal damage. In contrast, the adaptive immune response is driven by autoreactive T and B cells, which damage myelin and neurons through cytokine production and antigen presentation. Glial cells play context-dependent roles in both promoting neuroinflammation and supporting tissue repair. Key molecular mechanisms include MHC-mediated antigen presentation, complex networks of pro-inflammatory and anti-inflammatory cytokines and chemokines that regulate cell migration, colony-stimulating factors, and complement system activation. Current therapeutic approaches primarily emphasize immunomodulation and immunosuppression using agents such as interferon-β, glatiramer acetate, monoclonal antibodies, and inhibitors of cell migration. Recent therapeutic developments, including cellular therapies and strategies that modulate the gut microbiota, offer new avenues for improving disease control and promoting repair in MS.

This review systematically synthesises current strategies for generating these organoids through morphogen‑guided differentiation, their composition encompassing motor neurons, interneurons, astrocytes, and oligodendrocyte lineages, and the progressive incorporation of microglial and vascular elements to model neuroinflammation and barrier integrity. We critically appraise functional assessment techniques, including calcium imaging and multielectrode array recordings, alongside bioengineering advances such as microfluidic devices and bioprinting that improve structural organisation and experimental reproducibility.

We position LNNs in relation to spiking neural networks, recurrent neural networks, transformers, neural ordinary differential equations, and state-space models, and discuss their relevance to multimodal neural signal fusion, cortical hierarchical dynamics, brain-state transitions, dynamic disease prediction, and closed-loop neuromodulation.

These artificial intelligence (AI)-driven interfaces function as a “digital first-aid kit” for individuals experiencing mental health challenges. Offering anonymity, immediate 24/7 access, personalized interaction, and low cost, they are often used before any contact with a human clinician. By lowering barriers to care, these tools have unprecedented potential to help close the global mental health gap. At the same time, they carry inherent risks. As Opel and Breakspear noted,&lt;span&gt;&lt;sup&gt;1&lt;/sup&gt;&lt;/span&gt; generative AI is susceptible to hallucinations and may align excessively with user intent, generating misguided or unsafe guidance that, in extreme cases, could contribute to suicide risk. While hallucinations and other model-level failures remain important concerns and may be partially mitigated through domain-specific fine-tuning and reinforcement learning,&lt;span&gt;&lt;sup&gt;2&lt;/sup&gt;&lt;/span&gt; they represent only one side of AI-related risk. The safety of AI-mediated mental health support may also be shaped by user vulnerability, including how individuals interpret, trust, and respond to AI-generated outputs. Drawing on the biopsychosocial model, we propose that personality characteristics, developmental processes, clinical vulnerabilities, and social contexts may shape these responses (Figure 1).&lt;/p&gt;&lt;p&gt;In general, generative AI produces responses that are linguistically plausible rather than clinically grounded. Individuals frequently engage with chatbots as trusted peers, relying on emotional subtext and culturally grounded shorthand that current AI interfaces cannot reliably interpret. Particularly in those seeking emotional reassurance, this interaction may foster a perception of empathy and understanding that exceeds the actual capabilities of AI systems. Such perceptions may increase the likelihood of anthropomorphizing chatbots and relying on their guidance in emotionally salient situations. It is possible for individuals with attachment insecurity, interpersonal sensitivity, loneliness, reassurance-seeking tendencies, or dependency-related personality traits to be more likely to perceive AI as trusted social partners. This tendency may be particularly relevant in individuals with mental disorders; conditions frequently associated with interpersonal sensitivity and personality-related vulnerabilities. Across these disorders, altered functional networks involved in self-referential processing, salience detection, and cognitive control may increase susceptibility to external guidance, although direct evidence linking these neural alterations to AI overreliance remains limited. Within this context, reliance on AI advice may be shaped less by model accuracy alone but by user characteristics that influence trust, interpretation, and dependence on AI-generated guidance.
