TL;DR: A 2026 mixed-methods study in BMC Psychiatry found that adults in psychiatric treatment valued group-based physical activity less as generic exercise and more as structured, socially supported care, with 97% of questionnaire participants saying they felt supported by activity leaders. Key Findings Real-world psychiatric care: The program was embedded in an Oslo outpatient clinic …
TL;DR: A 2026 study in Signal Transduction and Targeted Therapy built a Parkinson’s visual hallucination mouse model and found that a combined behavior map identified hallucination-like episodes better than any single movement measure. Key Findings Model: Researchers used 6-OHDA to create Parkinson-like dopamine injury in male C57BL/6 mice, then used benzhexol hydrochloride to trigger Parkinson’s …
TL;DR: A 2026 preprint in medRxiv found that deep brain stimulation for severe obsessive-compulsive disorder was followed by lower globus pallidus externus alpha-band activity in clinically responsive patients, suggesting a possible brain readout of sustained DBS response. Key Findings 10 severe OCD patients: Researchers recorded local field potentials from the anterior globus pallidus externus (GPe) …
TL;DR: A 2026 mouse study in The Journal of Physiology found that damaging noise temporarily disrupted sound-offset responses in a brainstem hearing circuit, but those timing responses partly recovered within 24 hours through rapid circuit adaptation. Key Findings Sound-offset responses mark when sound ends: researchers studied neurons in the superior paraolivary nucleus (SPN), a brainstem …
TL;DR: A 2026 study in The British Journal of Psychiatry found that a single 50 mg dose of naltrexone reduced distress and shifted threat-related brain activity without blocking people’s ability to reappraise negative images. Key Findings 38 healthy volunteers completed a placebo-controlled crossover: Participants received naltrexone 50 mg and placebo on separate visits, then performed …
TL;DR: A 2026 Molecular Psychiatry study tested Regional Vulnerability Index for Alzheimer’s disease (RVI-AD), a structural-MRI score of how closely a person’s brain pattern resembles amyloid-positive Alzheimer’s disease, and found that higher RVI-AD predicted conversion from mild cognitive impairment to dementia most strongly in the first 3 years. Key Findings 571-person reference map: Researchers built …
TL;DR: A 2025 study in Journal of the American Chemical Society found that a depression-linked gut bacterium now has a concrete inflammatory mechanism: Morganella morganii can make unusual phospholipids that activate TLR2/TLR1 and drive IL-6. Key Findings Morganella got a molecule: The paper moved beyond a microbiome correlation by isolating pro-inflammatory metabolites made by M. …
TL;DR: A 2026 Research Square preprint used silent verb-generation functional MRI (fMRI), brain imaging during covert word production, and found early cerebellar-cerebral language-network changes after radiotherapy in 31 children and adolescents treated for medulloblastoma. Key Findings 31 pediatric patients: Children and adolescents with medulloblastoma completed silent verb-generation fMRI before radiotherapy and again within 6 weeks …
TL;DR: A 2026 medRxiv preprint reanalyzed long-term survivors from the AB10015 ALS trial and reported that masitinib-treated patients had higher 5-year survival than historical benchmarks, but the analysis was post hoc, sponsor-supported, and lacked long-term placebo follow-up. Key Findings Five-year survival was 42.3%: 55 of 130 patients assigned to masitinib 4.5 mg/kg/day were alive at …
TL;DR: A 2026 network meta-analysis in International Clinical Psychopharmacology found that lurasidone and xanomeline-trospium improved global cognitive scores in schizophrenia-spectrum randomized trials, while quetiapine and cariprazine ranked best for attention. Key Findings 14 randomized trials: Researchers analyzed 2,464 participants across trials of selected second- and third-generation antipsychotics plus xanomeline-trospium. Lurasidone improved global cognition: Lurasidone outperformed …
