This narrative review synthesizes five years of RCTs and observational studies on repetitive TMS, showing it can modulate both neuronal firing and the brain's blood-flow-activity coupling in networks supporting memory and executive function — spanning healthy older adults through Alzheimer's patients. The practical implication is that rTMS may offer a non-pharmacological lever across the full cognitive aging spectrum, not just in diagnosed disease. Confidence should be tempered: this is a single-database narrative review without a formal search protocol or PRISMA diagram, so effect size estimates cannot be taken at face value.

Using event-related brain potentials recorded while participants encoded emotional material, this study found that the neural signatures of emotional memory formation differ between people with anxiety and those with depression — suggesting these two commonly conflated conditions process threatening or distressing information through distinct brain mechanisms. This matters because it supports the case for disorder-specific biomarkers rather than transdiagnostic ones, which has direct implications for precision treatment targeting. If replicated with larger samples, these ERP differences could eventually guide which patients are routed to which intervention.

This study found that a single genetic variant in the regulatory region of the anti-inflammatory cytokine IL-10 changes how the level of that cytokine in the blood relates to cognitive ability in people with methamphetamine use disorder. In plain terms, the same immune signal predicts better or worse cognition depending on a person's genetic background — meaning population-average findings about inflammation and cognition may mask important subgroup differences. This adds nuance to the push for neuroinflammation biomarkers in psychiatric disorders: genotype may need to be part of any useful inflammatory biomarker panel.

This multidisciplinary analysis finds that new technologies introduced into healthcare routinely fail to deliver their promised benefits, with evidence of a consistent gap between initial claims and real-world outcomes. The mechanism is not simply technical failure but the complex social, organizational, and institutional processes through which technologies become embedded — or fail to — in clinical practice. For digital mental health therapeutics specifically, this is a useful corrective: the field's optimism about apps and AI tools needs to be interrogated against this broader pattern of ambivalent healthcare technology adoption.

This narrative review proposes that acupuncture ameliorates post-stroke cognitive impairment by acting as a multi-target regulator of mitochondrial function — reducing oxidative stress and correcting energy metabolism disorders that arise when mitochondria are damaged by stroke. The mechanism matters because it positions mitochondrial homeostasis as a druggable or stimulable pathway relevant to cognitive recovery, not just acute stroke injury. Reproducibility is low: the review lacks a systematic search strategy, PRISMA diagram, or explicit inclusion criteria, so the evidence base cannot be independently verified.

This review frames cerebral ischemia-reperfusion injury as driven by a self-reinforcing cycle between mitochondrial dysfunction and immune-inflammatory dysregulation, and argues that mesenchymal stem cells and their secreted products can interrupt this cycle at multiple points across different injury stages. The temporal dimension is the key novel framing: the same therapeutic target (mitochondria) may need different interventions depending on how far the pathological cascade has progressed. The evidence is entirely from preclinical models and narrative synthesis, limiting direct clinical translation.

A three-arm RCT with 180 preschoolers followed over 18 months found that an interactive story-based game intervention produced large improvements in working memory (effect size d=0.85) and inhibitory control (d=0.73) compared to controls, measured both behaviorally and via brain recordings. This matters because it provides quantified effect sizes for a scalable, low-cost intervention on executive functions that predict later mental health and academic outcomes. Confidence is limited: the study lacks documented pre-registration, assessor blinding, or allocation concealment, and the full data availability statement was not accessible for review.

Using EEG, this study shows that when people retrieve memories of negative images, the brain reinstates the neural patterns from the original viewing experience more strongly and earlier in the retrieval process than for neutral or positive images. This mechanism — neural recapitulation — may help explain why negative memories are often more vivid and intrusive than positive ones, a hallmark of depression and PTSD. The finding is relevant to developing objective neural markers of memory bias that could serve as biomarkers for mood disorders.

Analyzing brain imaging data from over 4,000 children in the ABCD Study, researchers found that boys — but not girls — with a history of mild traumatic brain injury showed measurable changes in hippocampal microstructure, and these changes were associated with better immediate verbal recall within the injured group. The sex-specificity is scientifically important because it suggests that the brain's vulnerability and compensatory response to mTBI differs by sex, which has implications for designing recovery interventions. This is a large, publicly available dataset, making the findings more reproducible than most in this area.

A systematic scoping review of eight databases finds that while technology-based neuropsychological testing improves access for rural and mobility-limited patients, actual implementation in clinical practice remains slow. Barriers include technology anxiety among patients, poor rural connectivity, and clinicians' concern that remote assessment strips away the observational nuance of in-person testing. This is directly relevant to digital mental health: even well-validated digital assessment tools face structural and attitudinal barriers that pure efficacy research does not address.
