sCD27 Biomarker Flags Autoimmune Disease in Severe Psychiatric Disorders

MHD featured image for sCD27, autoimmune disease, severe psychiatric disorders, and neuroinflammation biomarker triage.

A 2026 immunopsychiatry cohort study found that soluble CD27 (sCD27), a marker of T-cell activation, was positive in cerebrospinal fluid in 23% of severe psychiatric patients selected for suspected immune involvement and in 88% of multiple sclerosis patients used as a positive-control group. In the psychiatric cohort, combined cerebrospinal fluid or blood sCD27 positivity was …

Striatal Dopamine Drops From Psychosis to Schizophrenia Remission

Photoreal illustration of a brain with the striatum highlighted and dopamine synthesis pathways visualized, representing longitudinal PET imaging in schizophrenia.

The dopamine hypothesis of schizophrenia is the field’s longest-running mechanistic story, and most of its supporting evidence has been cross-sectional. A 2026 longitudinal PET study by Schulz and colleagues followed the same 28 patients across psychosis and early remission.1 Research Highlights The dopamine hypothesis of schizophrenia is the field’s longest-running mechanistic story. Cross-sectional 18F-DOPA PET …

Schizophrenia and Aging: Advanced, Not Accelerated

Two parallel timelines representing chronological vs. biological age in schizophrenia: an early offset at first episode, then parallel trajectories afterward — illustrating advanced rather than accelerated aging.

“Schizophrenia ages you faster” is the headline that gets repeated whenever a new biomarker study lands. The 2026 Fernandez-Egea, Garcia-Rizo and Kirkpatrick review — covering 170 studies across mortality, brain imaging, telomeres, epigenetic clocks, and metabolic markers — pushes back on that framing.2 The aging signal is genuine. “Accelerated” is the part that overshoots for …

Lupus Psychosis: 4.5% Prevalence and Antibody Predictors

Stylized illustration of autoantibodies and immune complexes crossing a disrupted blood-brain barrier, evoking the immune-mediated mechanism by which lupus produces psychosis.

Psychosis is one of 19 neuropsychiatric syndromes the American College of Rheumatology recognizes as attributable to systemic lupus erythematosus (SLE), an autoimmune disease that disproportionately affects young women.2 A 2026 systematic review and meta-analysis from Parperis and colleagues in Lupus pooled 65 studies and 31,495 patients.1 The synthesis matters less for the headline 4.5% prevalence …
