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 …

Early Psychosis Vocational Recovery: 53.3% NEET in SEEearly Trial

by GLOOM

MHD featured image for early psychosis, supported employment and education, and NEET status.

A 2026 SEEearly baseline report found that 53.3% of 184 young people with early schizophrenia-spectrum psychosis were not in employment, education, or training at study entry, even though 97.8% had at least a lower- or upper-secondary school-leaving qualification.1 Psychosis had already interrupted the bridge from school into training, college, or competitive work. Research Highlights NEET …

MTHFR C677T Linked to Schizophrenia With Type 2 Diabetes in Han Chinese

by GLOOM

Editorial card showing MTHFR genetics, folate metabolism, schizophrenia, and type 2 diabetes signals in a Han Chinese cohort.

A 2026 Han Chinese case-control preprint linked the MTHFR C677T variant to schizophrenia with type 2 diabetes: the 677T allele appeared in 81.67% of alleles in the comorbid group vs. 60.00% in controls (p = 0.009), while MTHFR promoter methylation was nearly saturated in both groups (95.00% vs. 90.00%; p = 1.000). Research Highlights Genetic …

Right OFC rTMS Improves Memory in Early Schizophrenia

by GLOOM

Editorial card showing a coronal brain section highlighting the right orbitofrontal cortex with a TMS coil, illustrating the first RCT of OFC stimulation in first-episode schizophrenia.

Cognitive impairment in first-episode schizophrenia (FES) is the symptom that does the most work blocking employment, relationships, and independent living — and the symptom current antipsychotics barely move. A 2026 RCT by Hu et al. in Psychological Medicine tested whether 20 sessions of low-frequency rTMS targeting the right orbitofrontal cortex (OFC) could improve cognition where …

PDE10A Inhibitor MK-8189 Fails Phase 2b Schizophrenia Trial

by GLOOM

Mukai et al.’s 499-person Phase 2b schizophrenia trial tested whether higher, sustained PDE10A inhibition could turn MK-8189 into a non-D2 antipsychotic; it did not. At week 6, MK-8189 missed the PANSS total endpoint at 16 mg (−2.8 points vs. placebo; 95% CI −8.3 to 2.6; P = 0.241) and 24 mg (−0.7 points; 95% CI …

Cognitive Reserve in First-Episode Psychosis: Education PRS Adds 4.2%

by GLOOM

Photoreal illustration of brain with strengthening neural networks suggesting reserve and protection against cognitive decline.

A 2026 analysis of 174 people with non-affective first-episode psychosis found that cognitive reserve was tied to 3 signals available near illness onset: age at onset, family history of psychosis, and polygenic liability for educational attainment. Adding the education polygenic score raised the model’s adjusted R² from 13.5% to 17.7%, a real but modest gain …

Gamma Brain Stimulation Helps Schizophrenia More Than Depression

by GLOOM

Photoreal illustration of gamma-frequency brain stimulation showing TMS coil and oscillation waveforms in 30-50 Hz range over a brain.

A 2026 meta-analysis of 56 controlled trials found the clearest gamma-frequency neuromodulation signal in schizophrenia: overall symptoms improved vs. control (g = −0.46), global cognition improved (g = 0.55), and MDD showed a smaller depression effect than the schizophrenia symptom estimate (g = −0.34). Bipolar disorder and autism stayed directional but nonsignificant, and the paper’s …
