Oral Acetate Case Series Found Metabolic Improvements in Psychotropic Weight Gain

TL;DR: A 2026 case-series study in Translational Psychiatry tested delayed-release oral acetate from apple cider vinegar capsules in 11 young adults taking psychotropic medications and found high adherence, no product-related adverse events, microbiome shifts, and metabolic improvement in 6 participants, but the uncontrolled design means the findings need placebo-controlled testing. Key Findings 11 completers: The …

GLP-1 Drugs Suppressed Reward Feeding Through a Central Amygdala Circuit

by
GLP-1 Drugs Suppressed Reward Feeding Through a Central Amygdala Circuit

TL;DR: A 2026 mouse study in Nature found that small-molecule glucagon-like peptide 1 receptor agonists (GLP-1RAs), obesity and diabetes drugs built around a glucose-linked hormone pathway, suppressed palatable-food intake through central amygdala neurons that lowered nucleus accumbens dopamine. Key Findings Humanized mouse model: Researchers engineered mice so small-molecule GLP-1 receptor agonists could be studied despite …

Consonant Chord Progressions With Face Gaze Increased Social Brain Activity

TL;DR: A 2026 study in The Journal of Neuroscience found that listening to consonant chord progressions while looking at a live partner increased functional near-infrared spectroscopy (fNIRS), a scalp blood-flow measure, in social brain systems. Key Findings Dyadic design: The study tested 20 participant pairs while both partners were recorded at the same time. Two …

Ketamine’s Antidepressant Pathway Reverse-Engineered: Low-Dose Three-Drug Combination Reproduced Effect in Mice

by
Ketamine's Antidepressant Pathway Reverse-Engineered: Low-Dose Three-Drug Combination Reproduced Effect in Mice

TL;DR: A 2026 mouse study in Cell traced ketamine’s rapid antidepressant-like effect to mu-opioid receptors on somatostatin-positive interneurons in the medial prefrontal cortex. Low-dose multi-GPCR targeting reproduced ketamine-like effects in mice, but the exact three compound names were not listed in the public source material verified here. Key Findings Cell target: ketamine’s rapid mouse effect …

Caudal Insular-to-Somatosensory Pathway Was Necessary and Sufficient for Neuropathic Pain in Rats

by
Caudal Insular-to-Somatosensory Pathway Was Necessary and Sufficient for Neuropathic Pain in Rats

TL;DR: A 2025 rat study in The Journal of Neuroscience found that caudal granular insular cortex (CGIC) projections to primary somatosensory cortex (SI) were required for neuropathic pain behavior, while activating the same pathway produced allodynia, or pain from harmless touch, in healthy rats. Key Findings CGIC-to-SI projections are necessary for neuropathic pain: Multiweek chemogenetic …

Lurasidone 40 mg Improved Five PANSS Symptom Domains in Acute Schizophrenia

TL;DR: A 2026 post-hoc analysis in International Clinical Psychopharmacology found that lurasidone 40 mg/day improved all 5 Positive and Negative Syndrome Scale (PANSS) symptom domains in acute schizophrenia over 6 weeks, with the largest effect on positive symptoms and later improvement in negative symptoms. Key Findings 483 randomized patients: The JEWEL phase 3 trial assigned …

Kynurenine Metabolites Were Higher in Inflammatory Depression

by
Kynurenine Metabolites Were Higher in Inflammatory Depression

TL;DR: A 2026 biomarker analysis in Brain, Behavior, & Immunity – Health across antidepressant trials found that kynurenine pathway metabolites were elevated in inflammatory depression compared with non-inflammatory depression and healthy controls, while omega-3 polyunsaturated fatty acid treatment reduced several kynurenine pathway metabolites. Key Findings Study type: a combined analysis of two depression trials testing …

IGF1R Inhibitors Improved Mouse Healthspan but Raised Safety Concerns

TL;DR: A 2026 mouse preprint in bioRxiv reported that small-molecule IGF1R inhibitors, drugs that block insulin-like growth factor 1 receptor signaling, protected several healthspan measures in aging mice, but the tested compounds also carried major safety and drug-development problems. Key Findings 150 aging mice: Researchers assigned 55-week-old C57BL/6 mice to control diet, PPP, or NVP-ADW742, …

Household Pesticide Exposure Was Associated With Depression Risk

by
Household Pesticide Exposure Was Associated With Depression Risk

TL;DR: A 2026 cross-sectional NHANES analysis in Depression and Anxiety found that urinary pyrethroid metabolite 3-PBA showed a dose-dependent association with depression, while female participants showed stronger associations for 3-PBA and 4F-3-PBA, while males showed sensitivity to DCBA in mixture models. Key Findings Study type: a survey-weighted analysis using self-reported pesticide exposure and urinary pesticide …

Home DBS Recordings Tracked Depression Recovery Biomarkers

by
Home DBS Recordings Tracked Depression Recovery Biomarkers

TL;DR: A 2026 preprint deep brain stimulation biomarker study in medRxiv found that home-recorded electrophysiology biomarkers tracked stable depression recovery during SCC DBS, while the biomarkers helped distinguish recovery from nonspecific symptom fluctuations and external distress. Key Findings Study type: a home-recording study using bidirectional deep brain stimulation devices to monitor electrophysiology during depression recovery. …
