Depression vs. Schizophrenia: Microglial TSPO and KYNA Signals

by GLOOM

MHD featured image for microglial and kynurenine pathway patterns across depression, bipolar disorder, and schizophrenia.

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 …

24-Minute Yoga Did Not Lower Cortisol in a 19-Person Stress Pilot

by GLOOM

MHD featured image for acute yoga and stress biomarkers.

A 2026 randomized exploratory pilot found that a single 24-minute yoga session did not significantly lower salivary cortisol or salivary alpha-amylase compared with quiet sitting in 19 stressed adults.1 The acute yoga signal was physiological but not the simple stress-biomarker drop that wellness claims often imply. Research Highlights Biomarker claim failed: Yoga did not significantly …

Depressive Symptoms Rose 4 Years Before Death in Twins

by GLOOM

MHD featured image for late-life depressive symptoms, terminal decline, twin studies, and mortality.

In a 2,411-person multinational twin-consortium study, depressive symptoms increased significantly as death approached. The strongest design check compared twins directly: twins who died had larger terminal symptom increases than co-twins who survived at least 4 more years. Research Highlights Terminal mood change was visible: Petkus et al. found accelerated depressive-symptom increases roughly 4.3 years before …

Cerebellar Gray Matter Separated Bipolar From Unipolar Depression

by GLOOM

MHD featured image for cerebellar gray matter differences in bipolar and unipolar depression.

A 2026 structural MRI study found that cerebellar gray-matter patterns helped distinguish first-episode bipolar depression from unipolar depression: a model using significant cerebellar lobules reached 76.3% accuracy and AUC 0.779.1 The result is best read as proof-of-concept neuroimaging evidence, not as a scan-based bipolar diagnostic test. Research Highlights Classifier performance was moderate: cerebellar lobules with …

Rwanda Resiliency Training Improved Forgiveness and Social Cohesion

by GLOOM

MHD featured image for Rwanda Community Resiliency Model training and social cohesion.

A 2026 randomized comparison study of 152 Rwandan genocide survivors and released perpetrators found that 3-day Community Resiliency Model training improved social cohesion, compassion, forgiveness, and resilience over time, with social cohesion F(1) = 36.1, compassion F(1) = 131, forgiveness F(1) = 19.8, and resilience F(1) = 8.10.1 Mixed survivor-perpetrator groups improved slightly more, but …

Environmental Enrichment Reversed Visceral Pain and Depression in Rats

by GLOOM

MHD featured image for environmental enrichment, visceral pain, depression, and CB1 receptor circuitry.

A 2026 Communications Biology rat study found that enriched housing reversed early-life-stress visceral hypersensitivity and depression-like behavior by normalizing a CB1 receptor-linked prefrontal-limbic circuit connecting prelimbic cortex, anteroventral bed nucleus of the stria terminalis, and paraventricular hypothalamus.1 Huang et al. mapped a gut-pain and mood circuit in rats, but the experiment does not prove that …

MIND Migraine Study Completed 3,688 Smartphone Cognition Assessments

by GLOOM

MHD featured image for the MIND migraine smartphone cognition feasibility cohort.

The MIND migraine feasibility study showed that remote migraine-cognition monitoring can produce a large daily dataset: 177 baseline participants completed 3,688 smartphone assessments, covering 70.8% of possible study days.1 The finding supports digital migraine endpoint infrastructure while leaving treatment effects and diagnostic thresholds untested. Research Highlights Daily monitoring was feasible: Participants completed 3,688 daily smartphone …
