TL;DR: A 2026 study in The British Journal of Psychiatry found that in first-episode psychosis, MRI deviations from age-matched brain norms at illness onset helped predict which patients would carry heavier symptom burdens and poorer functioning for years afterward. Key Findings 100,000-scan reference model: Researchers used a lifespan normative MRI model built on more than …
TL;DR: A 2026 network analysis study in European Archives of Psychiatry and Clinical Neuroscience found that insomnia was present in 18.3% and childhood trauma in 49.5% of patients, while daytime dysfunction and sleep-related distress were central nodes, while mood symptoms and difficulty falling asleep bridged domains. Key Findings Evidence map: a network analysis connecting childhood …
TL;DR: A 2026 systematic review and meta-analysis in Neuropsychopharmacology found that dopamine D2-like receptor activation suppressed glucose-stimulated insulin secretion (GSIS), insulin release after high glucose, in animal pancreatic cells, suggesting one peripheral route by which antipsychotic dopamine blockade can disturb glucose control beyond weight gain. Key Findings 39 eligible studies: Researchers screened 12,457 citations and …
TL;DR: A 2026 systematic review in The British Journal of Psychiatry linked schizophrenia to a multisystem advanced-aging phenotype, including older-appearing brain scans, shorter telomeres, inflammation, and higher dementia risk. Key Findings 170 studies included: The review synthesized studies of aging markers in schizophrenia and non-affective psychosis published after 2009. Most studies were moderate or high …
TL;DR: A 2026 medRxiv preprint on schizophrenia reported that illness insight tracked with resting-state functional MRI (fMRI) flexibility, a measure of how dynamically brain regions reconfigure their connectivity, and that these brain-dynamics patterns aligned with dopamine D2 and serotonin 5-HT2A receptor maps after accounting for antipsychotic receptor occupancy. Key Findings Two insight subtypes: Clinical clustering …
Connexin 36 Loss Disrupted Thalamocortical Synchrony TL;DR: Deleting connexin 36 left broad sleep architecture mostly intact but disrupted fast brain electrical rhythms measured by electroencephalography (EEG), along with sensory-response markers often discussed in neuropsychiatric disease. Key Findings Sleep architecture mostly held: Cx36 knockout mice did not show a broad collapse of sleep-wake organization. Fast rhythms …
Childhood Loneliness Multiplied Psychosis Risk in EU-GEI TL;DR: Loneliness that started before age 12 and persisted into adolescence tracked with sharply higher schizophrenia-spectrum risk, especially when it stacked on top of genetic liability. Key Findings Persistent loneliness carried the risk signal: The EU-GEI analysis included 1,261 people with schizophrenia-spectrum disorders, 1,282 unaffected siblings, and 1,525 …
Mediodorsal Thalamus Activity Restored Belief Updating TL;DR: A Nature Neuroscience mouse study linked a schizophrenia-risk Grin2a mutation to weaker mediodorsal thalamus activity, impaired belief updating, and behavioral rescue when researchers reactivated the thalamus-prefrontal circuit during flexible decision-making in mice. Key Findings Grin2a was the genetic entry point: The mutation affects an NMDA receptor subunit gene …
AVATAR Therapy Outlasted CBT for Auditory Hallucinations TL;DR: AVATAR therapy matched CBT on voice severity right after treatment, then pulled ahead at 3 months — with roughly half the sessions. A 26-trial meta-analysis, 2,273 patients. Key Findings No clear edge at treatment end: AVATAR did not significantly beat CBT on voice severity right after therapy …
C4A Broke Away From C1Q in First-Episode Psychosis TL;DR: In cerebrospinal fluid from people with first-episode psychosis, the usual positive relationship between C4A and C1Q disappeared, while C4A’s broader immune-network pattern shifted sharply in a way C4B did not. Key Findings C4A-C1Q coupling broke in psychosis: The study compared 113 patients with first-episode psychosis against …
