Mental Health Apps Split Depression, Anxiety, and Workplace Well-Being Effects

TL;DR: A 2026 randomized trial in JMIR Mental Health found that a 4-week executive-function training app reduced depression and anxiety symptoms at 12-week follow-up, while a self-guided CBT app mainly improved workplace well-being. Key Findings Workplace app trial: Participants with mild-to-moderate depression and anxiety symptoms were assigned to waitlist control, NeuroNation executive-function training, or Moodfit …

Angiopep NK Vesicles Delivered Temozolomide in Glioblastoma Mice

by
Angiopep NK Vesicles Delivered Temozolomide in Glioblastoma Mice

TL;DR: A 2026 study in Journal of Nanobiotechnology found that Angiopep-2-modified natural killer cell extracellular vesicles carried temozolomide across glioblastoma barriers, reduced mouse tumor bioluminescence, and extended median survival in an orthotopic GBM model. Key Findings 2.5-3.2x uptake: Angiopep-2 modification increased glioblastoma-cell uptake of NK extracellular vesicles compared with unmodified NK-EV. 2.8-3.5x BBB transport: Ang-NK-EV@TMZ …

Amyloid, Tau, and Neurodegeneration Axes Mapped Alzheimer’s Heterogeneity

by
Amyloid, Tau, and Neurodegeneration Axes Mapped Alzheimer's Heterogeneity

TL;DR: A 2026 preprint in medRxiv used amyloid positron-emission tomography, tau molecular imaging, and structural MRI to build individualized Alzheimer’s disease biomarker axes from ADNI and validate them in OASIS. Key Findings 12,430 ADNI images: The pipeline harmonized longitudinal amyloid-beta and tau positron-emission tomography images plus T1 MRI gray matter images from ADNI. 4,958 OASIS …

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

by
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

by
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

by
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 …

Neonatal Gyri Showed Stronger Brain Connectivity Than Sulci

by
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

by
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 …

Chicory and Green Tea Sleep Supplement Did Not Beat Placebo in Insomnia Pilot

by
Chicory and Green Tea Sleep Supplement Did Not Beat Placebo in Insomnia Pilot

TL;DR: A 2026 pilot trial in PLOS One found that a 7-day chicory-and-green-tea herbal supplement did not improve sleep, quality of life, or objective sleep architecture more than placebo in adults with insomnia. Key Findings Small crossover pilot: The crossover pilot enrolled 10 adults aged 50 years or older with insomnia; 9 were women and …

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 …
