SMART Text Messages Improved Self-Management in Schizophrenia Metabolic Health Pilot

TL;DR: A 2026 uncontrolled pilot study in BJPsych Open found that SMART, a personalized text-message program for metabolic health in people with schizophrenia spectrum disorders, improved patient activation, diabetes self-management confidence, health literacy, and recovery scores over 12 weeks, while objective cardiometabolic markers did not significantly change. Key Findings SMART reached a schizophrenia-risk group: Researchers …

Singing Mouse Orofacial Motor Cortex Showed 2.8-Fold and 3.3-Fold Expansion of Projections to Auditory Cortex and PAG

TL;DR: A 2026 mouse study in Nature mapped more than 76,000 single-neuron projections from the orofacial motor cortex (OMC) and found that Alston’s singing mouse, which produces audible song, has 2.8-fold higher OMC connectivity to an auditory cortical region and 3.3-fold higher OMC connectivity to the midbrain periaqueductal grey (PAG) than the laboratory mouse. Key …

Serum MOG Protein Was Higher in Multiple Sclerosis Relapse

TL;DR: A 2026 preprint in medRxiv reported that serum myelin oligodendrocyte glycoprotein (MOG) protein was higher in multiple sclerosis than controls and higher during clinical relapse than remission. Key Findings 20.5 pg/ml higher: Serum MOG protein was higher in MS than healthy donors by a mean difference of 20.5 pg/ml. 27.5 pg/ml higher: MS samples …

A Specific Serotonergic Brain Circuit Produced Tinnitus-Like Behavior in Mice and Explains SSRI-Tinnitus Reports

TL;DR: A 2026 study in PNAS from Oregon Health & Science University and Anhui University used optogenetics in mice to map a specific serotonin-producing brain circuit that runs straight to the auditory system, showed that activating this circuit produced tinnitus-like behavior, and traced a likely mechanism for why some patients on SSRI antidepressants report worsened …

Seasonal Circadian Disruption May Increase Driver Drowsiness and Crash Risk

TL;DR: A 2026 scoping review in Sleep Science linked seasonal timing, daylight exposure, daylight saving time (DST), sleep-wake rhythm disruption, and driver drowsiness to traffic-crash risk, but found that few studies directly integrate seasonality with chronobiology in one model. Key Findings 1,758 records screened: The scoping review used PRISMA-ScR methods and screened 1,758 records before …

Risperidone Was Linked to Higher Stroke Risk in Dementia

TL;DR: A 2026 population-based matched cohort study in British Journal of Psychiatry found that risperidone use was associated with increased stroke risk, adjusted hazard ratio 1.28, while absolute stroke incidence was especially high in people with prior stroke or cardiovascular disease. Key Findings Matched dementia comparison: The analysis compared stroke risk among risperidone users and …

Refugee PTSD Trial Found No Overall STAIR-R Advantage Before NET

TL;DR: A 2026 randomized pilot trial in European Journal of Psychotraumatology found no overall PTSD advantage when refugee-focused emotion-regulation skills training was added before narrative exposure therapy, but refugees living with high visa or family insecurity showed preliminary self-report gains from the skills-first approach. Key Findings 71 adult refugees were randomized: Participants met DSM-5 criteria …

PAP Mask Leak Predicted Lower Sleep Apnea Treatment Adherence

TL;DR: A 2026 HomePAP secondary analysis in Journal of Clinical Sleep Medicine found that higher PAP mask leak predicted lower obstructive sleep apnea treatment adherence, but a new Real Leak measure, unintentional leak after subtracting expected mask leak, did not outperform conventional Average Leak. Key Findings HomePAP sample size: PAP data were available for 139 …
