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 …

Digital Mindfulness for GAD: Machine Learning Predicted App Engagement

by GLOOM

MHD featured image for digital mindfulness engagement prediction in generalized anxiety disorder.

A 2026 machine-learning analysis of 110 adults with generalized anxiety disorder predicted 2-week digital mindfulness engagement with R2 = 82.1% in a top-10 predictor model, and the model favored mindfulness prompts over self-monitoring prompts for engagement (d = 1.447, p < .001).1 The calibrated read is that engagement with brief app-based mindfulness may be matchable, …

GABA and Dopamine Shape Human Speech Control in PET-fMRI Study

by GLOOM

MHD featured image for GABA and dopamine interactions during human speech control.

A 2026 PET-fMRI study of 20 healthy adults found that GABAA receptor binding tracked speech-production brain activity across frontal, temporal, parietal, putaminal, supplementary motor, and cerebellar regions, with peak GABA-BOLD correlations reaching Rs = 0.9.1 Human speech control looks less like a pure motor-output problem and more like a task-specific balance between inhibition, dopamine, and …

Early Mental Illness Severity Tracks Genetics and Brain Volume in PRONIA

by GLOOM

MHD featured image for transdiagnostic early mental illness severity, genetics, and brain volume.

A 2026 PRONIA preprint involving 727 discovery-sample participants found that early mental illness severity cut across psychosis risk, recent psychosis, and recent depression: groups with higher symptom severity also had poorer functioning, higher schizophrenia and depression polygenic risk, and lower gray matter volume. Research Highlights Severity crossed diagnostic labels: Ye et al. stratified 727 participants …

Body Dysmorphic Disorder and Perfectionism: r = 0.32 Meta-Analysis

by GLOOM

MHD featured image for body dysmorphic disorder and perfectionism meta-analysis.

A 2026 meta-analysis of 34 studies involving 13,107 participants found that body dysmorphic disorder symptoms and perfectionism were moderately correlated: r = .32, 95% CI 0.28 to 0.36, p < .001. The result supports perfectionism as a useful clinical clue in body dysmorphic disorder, but the estimate dropped to r = .09 after depression adjustment …

PTSD Social Function Therapy Improved Family Function in Older Veterans

by GLOOM

MHD featured image for PTSD social-function group therapy in older veterans.

A 2026 pilot randomized trial involving 36 older U.S. veterans with PTSD symptoms found that a structured social-function group therapy produced stronger signals for romantic and family functioning than a support group, with condition-by-time effects of eta-squared = 0.072 and eta-squared = 0.112. The same trial did not show a specific advantage for friendships and …

Autism vs. ADHD Connectome Study: Frontal-DMN Signal Tracks Autism Severity

by GLOOM

MHD featured image for autism, ADHD, and connectome-based symptom mapping.

A 166-child resting-state fMRI study found that clinician-observed autism severity, not ADHD severity, tracked connectivity strength between a left middle frontal gyrus node and the posterior cingulate/default mode network across children diagnosed with autism or ADHD without autism. The result is transdiagnostic, but asymmetrical: autism traits carried the connectome signal after ADHD ratings were controlled.1 …
