A 2026 mixed-methods study of group physical activity inside psychiatric treatment found that 90% of participants joined to have a healthy body and get fresh air, 97% felt supported by activity leaders, and 91% wanted to stay active with others after treatment.1 The useful message is not “tell people with severe mental illness to exercise”; …
A 124-person study of euthymic bipolar disorder found that patients with early systematic antidepressant treatment history had higher negative affect, attentional impulsivity, non-planning impulsivity, and total BIS-11A impulsivity scores than matched patients without that history.1 The association is clinically cautionary, but the cross-sectional design cannot separate antidepressant effects from delayed bipolar diagnosis or more severe …
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 244-person functional MRI study found no significant evidence that ventral striatum activation during reward anticipation works as an endophenotype — a measurable trait used to connect inherited risk with diagnosed illness — for bipolar and psychotic disorders. Research Highlights The registered hypothesis failed: Barendse et al. found no significant ventral striatum reward-anticipation difference among …
Psychiatric brain biomarkers have produced a large research literature but little routine clinical use. A 2026 evidence map found 441 primary studies and 27 systematic reviews of neuroimaging or neurophysiologic biomarkers for mental-health disorders, yet the field still looks too small, cross-sectional, and depression-heavy for ordinary diagnostic or treatment decisions.1 Research Highlights Large map, weak …
A 2026 resting-state fMRI study of 800 adults found intra-thalamic hypoconnectivity across schizophrenia, bipolar disorder, and major depression, but schizophrenia showed far broader subcortical dysconnectivity than bipolar disorder or depression.1 The calibrated read is that these diagnoses may share a thalamic vulnerability while diverging in striatal and limbic circuitry. Research Highlights Shared thalamic deficit: In …
A 60-patient randomized trial of lithium loading for acute bipolar I mania reported faster serum lithium attainment than standard titration and a larger 14-day Young Mania Rating Scale (YMRS) change score, but the same accepted manuscript says absolute YMRS scores at Days 3, 7, and 14 were not significantly different between the 2 arms when …
