Early Antidepressants Linked to Bipolar Impulsivity During Euthymia

by GLOOM

MHD featured image for early antidepressant exposure and impulsivity in bipolar disorder.

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 …

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 …

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 …

Reward Activation Failed as Bipolar-Psychosis Endophenotype

by GLOOM

MHD featured image for reward brain activation and bipolar-psychosis endophenotype testing.

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 …

Apple Cider Vinegar for Psychotropic Weight Gain: 11 Cases

by GLOOM

MHD featured image for apple cider vinegar capsules, psychotropic weight gain, metabolic side effects, and gut microbiome changes.

An 11-person case series tested delayed-release apple cider vinegar capsules in young adults who had gained weight while taking psychotropic medications, and metabolic markers carried more signal than weight loss. Research Highlights Feasibility was the strongest result: 11 of 12 enrolled participants completed the study, 10 of 11 completers missed 5 or fewer doses, and …

Subcortical Connectivity Differs in Schizophrenia, Bipolar, Depression

by GLOOM

MHD featured image for subcortical connectivity patterns across schizophrenia, bipolar disorder, and depression.

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 …

Lithium Loading Dose Did Not Clearly Beat Standard Acute-Mania Titration

by GLOOM

Photoreal illustration of lithium tablets and blood-level monitoring chart, conveying acute-mania pharmacological strategy.

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 …
