Laypeople Named More Alcohol Than Cannabis Intoxication Cues

Laypeople Named More Alcohol Than Cannabis Intoxication Cues

TL;DR: A 2026 study in Drug and Alcohol Review found that laypeople reported more and better-developed cues for alcohol intoxication than cannabis intoxication, even though most coded cues for both substances were accurate. Key Findings Intoxication-cue sample: The survey sample was 77.7% female, with an average age of 20.5 years, and came from undergraduate psychology …

AI Remote Monitoring Studies Favored Parkinson’s but Had High Bias Risk

AI Remote Monitoring Studies Favored Parkinson's but Had High Bias Risk

TL;DR: A 2026 systematic review in BMC Medical Informatics and Decision Making found that AI models using remote-monitoring data were most often studied in Parkinson’s disease, but 56 of 76 prospective studies had high risk of bias. Key Findings 6,668 records were screened: Researchers narrowed the search to 76 prospective studies of machine learning for …

ADAS-Cog-13 Flagged Cognitive Impairment in Older Adults With Focal Epilepsy

ADAS-Cog-13 Flagged Cognitive Impairment in Older Adults With Focal Epilepsy

TL;DR: A 2026 preprint in medRxiv found that the ADAS-Cog-13 cognitive scale detected impairment in older adults with focal epilepsy, but a cutoff of 15 had only modest diagnostic accuracy against an epilepsy-specific neuropsychological standard. Key Findings 83 epilepsy patients: The study analyzed adults older than 55 with focal epilepsy from the Brain, Aging, and …

PF-04995274 5-HT4 Agonist Changed Depression Signals Without SSRI-Like Bias Shift

PF-04995274 5-HT4 Agonist Changed Depression Signals Without SSRI-Like Bias Shift

TL;DR: A 2026 randomized study in The British Journal of Psychiatry found that the experimental 5-HT4 receptor agonist PF-04995274 did not mimic citalopram’s early emotional-bias effects in unmedicated depression, but it was linked with lower depression ratings and increased medial-frontal brain activation after about 1 week. Key Findings 90 randomized adults: The RESTAND study assigned …

Psilocybin AUD Trial Found Exploratory TLE4 and RASGRP4 Methylation Signals

Psilocybin AUD Trial Found Exploratory TLE4 and RASGRP4 Methylation Signals

TL;DR: A 2026 exploratory study in Translational Psychiatry found blood DNA methylation changes after 25 mg psilocybin in detoxified alcohol use disorder patients, including findings near TLE4 and RASGRP4, but the small trial did not establish a definitive AUD biomarker. Key Findings 37 AUD patients: The methylation analysis used a randomized, double-blind psilocybin trial completed …

Neonatal Gyri Showed Stronger Brain Connectivity Than Sulci

Neonatal Gyri Showed Stronger Brain Connectivity Than Sulci

TL;DR: A 2026 study in Human Brain Mapping found that full-term neonates already showed stronger structural and functional connectivity between cortical gyri than between sulci, with brain structure-function coupling shifting toward decoupling around 41 weeks postmenstrual age. Key Findings Neonatal imaging sample: Researchers analyzed full-term neonates from the developing Human Connectome Project scanned between 38.14 …

Leigh Syndrome Organoid Drug Screen Identified Talarozole and Sertaconazole

Leigh Syndrome Organoid Drug Screen Identified Talarozole and Sertaconazole

TL;DR: A 2026 study in Nature Communications used deep learning, yeast screening, and human brain organoids to identify talarozole and sertaconazole as preclinical candidates that rescued several SURF1-related Leigh syndrome cell and organoid phenotypes. Key Findings 2,250-drug yeast screen: Researchers screened a repurposable-drug library in a yeast model carrying a SURF1-homologue defect and selected top …

MSC Membrane Nanoparticles Improved Doxorubicin-Curcumin Glioblastoma Delivery

MSC Membrane Nanoparticles Improved Doxorubicin-Curcumin Glioblastoma Delivery

TL;DR: A 2026 preclinical study in the International Journal of Nanomedicine developed human umbilical cord mesenchymal stem cell membrane-coated PLGA nanoparticles to co-deliver doxorubicin and curcumin to glioblastoma models, improving tumor-cell uptake and mouse tumor suppression without proving human efficacy. Key Findings MSC membrane coating: Researchers coated PLGA nanoparticles with human umbilical cord mesenchymal stem …

Dentate Nucleus Deep Brain Stimulation Improved Cerebellar Ataxia Symptoms Across 27 Patients in Systematic Review

Dentate Nucleus Deep Brain Stimulation Improved Cerebellar Ataxia Symptoms Across 27 Patients in Systematic Review

TL;DR: A 2026 systematic review in The Cerebellum found that deep brain stimulation (DBS) produced modest symptom improvement in selected cerebellar ataxia patients, with dentate nucleus stimulation most common in humans and interposed nucleus stimulation emerging from animal studies. Key Findings Dentate nucleus is the dominant human DBS target: Across 15 clinical studies (27 patients), …

Amygdala-ACC Connectivity Was Reduced in Anxiety Disorders Meta-Analysis

Amygdala-ACC Connectivity Was Reduced in Anxiety Disorders Meta-Analysis

TL;DR: A 2026 meta-analysis in Psychological Medicine found that reduced resting-state connectivity between the amygdala and anterior cingulate cortex was the most robust brain-network difference in anxiety disorders. Key Findings 15 datasets: The meta-analysis pooled 14 studies with 15 independent datasets of amygdala-based resting-state functional MRI. 783 total participants: Included samples covered 378 people with …
