A 40-person pilot trial found depression remission in 69% of adults who did 30 minutes of moderate exercise before individual CBT, compared with 33% of adults who did a calming pre-CBT activity.1 Compared with a broad “exercise boosts therapy” claim, acute exercise is a plausible priming step; the alliance and activation mechanisms still need a …
A 2026 Add Health analysis found that combining major-depression and alcohol-use-disorder polygenic scores added 4.88% variance for comorbid MDD-AUD prediction, while same-trait scores added only 0.65% for MDD and 1.52% for AUD alone.1 The genetic signal is strongest where the clinical problem is hardest: depression plus alcohol-use disorder, not either diagnosis in isolation. Research Highlights …
A 2026 systematic review found that microglia-related immune signals do not line up cleanly with psychiatric diagnosis labels: major depression showed frontolimbic TSPO-PET increases, while schizophrenia showed elevated kynurenic acid in cerebrospinal fluid.1 The strongest interpretation is that immune-brain markers may sort subgroups better than DSM categories do. Research Highlights Depression had the clearest TSPO-PET …
A 2025 Journal of the American Chemical Society study identified 4 unusual Morganella morganii phospholipids that activated TLR2/TLR1 immune receptors and induced inflammatory cytokines, especially IL-6.1 The finding does not prove that one gut bacterium causes depression, but it gives the microbiome-depression field something it often lacks: a named molecule and a receptor pathway. Research …
A 2026 biomarker study found kynurenine-pathway activation in inflammatory major depressive disorder (MDD), but not across all depression cases. Compared with non-inflammatory MDD and healthy controls, the inflammatory subgroup had higher pathway metabolites, and omega-3 treatment reduced several of them over 8 weeks.1 Research Highlights Inflammatory depression showed kynurenine activation: people with MDD and high-sensitivity …
Whole-body hyperthermia looks less like generic relaxation and more like a timed biological stressor: in a small depression substudy, a single session was followed by early Hamilton Depression Rating Scale improvement, heat-shock gene activation, and immune-process enrichment that included interleukin 6 production. Research Highlights Depression scores improved early: in the 18-person RNA sequencing substudy, whole-body …
A 25-person pilot study of young adults found an ATP fatigue pattern that was directionally reversed from the simple “low brain energy” story: the depression group had higher visual-cortex ATP production metrics than healthy controls, while fatigue severity correlated with ATPase production rate, r = 0.73, p = 0.006.1 The cleaner interpretation is compensatory strain, …
