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 …
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 …
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 …
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 …
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 …
A 2026 medRxiv preprint using parent-cocreated sensory-related outcome measures found that 83% of children and teens improved on at least 1 PROMIS domain during 6 months of bumetanide treatment.1 The result is interesting, but the unmasked single-case design means the strongest claim is about sensitive outcome tracking, not definitive bumetanide efficacy. Research Highlights Most participants …
A 2026 medRxiv preprint involving 44 people with chronic post-stroke aphasia found reduced performance on nonverbal false-belief tasks in 23% of participants on the Reality-Unknown task and 36% on the Reality-Known task, with accuracy tied more clearly to cerebral microbleed burden than to aphasia severity.1 The result reframes social-cognitive testing after stroke as a vascular …
