TL;DR: A 2026 laboratory study in ACS Omega reported that a laser-induced graphene sensor detected dopamine across a controlled range in artificial human tears, supporting a possible noninvasive biomarker-monitoring route that still needs real human tear testing. Key Findings Laser-induced graphene sensor: Researchers built a small electrochemical device on a plastic film converted into conductive …
TL;DR: A 2025 medRxiv fMRI preprint linked higher apathy in both traumatic brain injury (TBI) and control groups to greater effort discounting, while TBI-related apathy was also associated with less exploratory decision-making and weaker neural encoding of differences between expected and received rewards. Key Findings 53-person fMRI sample: Researchers analyzed 34 people with chronic TBI …
TL;DR: A 2026 preprint in medRxiv reported that people living with dementia (PLwD) and carers were generally open to artificial intelligence (AI) support in structured medication reviews, but only when AI remained validated, transparent, secure, and subordinate to human clinical judgement. Key Findings 26-person qualitative sample: Researchers interviewed 12 people living with dementia and ran …
TL;DR: A 2026 preprint in medRxiv found that routine non-contrast brain computed tomography (CT) had a low acute-pathology yield in 291 emergency patients with new dizziness, while diabetes, ataxic gait, and headache marked higher odds of abnormal CT findings. Key Findings 291-patient cohort: The retrospective analysis included consecutive adults with new-onset dizziness who underwent non-contrast …
TL;DR: A 2026 medRxiv preprint used functional MRI (fMRI) and complex harmonics decomposition to study mindfulness-based cognitive therapy in 80 people with major depressive disorder, reporting post-treatment changes in whole-brain manifolds during rumination. Key Findings 80-patient trial sample: The preprint analyzed fMRI data from a randomized controlled trial in major depressive disorder. MBCT plus TAU: …
TL;DR: A 2026 Nature Communications paper introduced EmulatRx, a multi-agent AI framework that used real-world clinical data to help design target-trial-emulation workflows for acute and chronic diseases, including Alzheimer disease and Parkinson disease examples. Key Findings 20-trial evaluation: Researchers curated 20 clinical trials, with 10 acute-condition trials from MIMIC-IV and 10 chronic-disease trials from INSIGHT. …
TL;DR: A 2026 systematic review and meta-analysis in Archives of Women’s Mental Health linked prenatal active tobacco smoking with higher odds of postpartum depression, while secondhand smoke and electronic nicotine-product estimates were not statistically clear. Key Findings 29-study review: Researchers included 29 studies in the systematic review and 26 studies in the meta-analysis. 15% pooled …
TL;DR: A 2026 case-control study in Psychological Medicine linked major depressive disorder to faster blood-based transcriptomic aging and found that right-insula brain changes partly explained the depression association. Key Findings Transcriptomic aging was faster in depression: 141 people with major depressive disorder showed higher blood RNA-based aging acceleration than 134 healthy controls. The result strengthened …
TL;DR: A 2026 randomized trial in Molecular Autism found that a culturally adapted parent-implemented social communication program was linked to language, social-functioning, parent self-efficacy, and stress gains in Chinese-speaking autistic preschoolers, with no consistent advantage for therapist-led online groups over self-study across most outcomes. Key Findings Chinese preschoolers randomized: 112 autistic children aged 24-60 months …
TL;DR: A 2026 meta-analysis in PLOS One found clinically important sleep problems in refugee and asylum-seeking populations, with pooled sleep-adversity prevalence of 43.2% in adults and 36.4% in children and adolescents. Key Findings 66 studies reviewed: The systematic review and meta-analysis covered 42,956 refugees and asylum seekers. 43.2% adult prevalence: Pooled sleep-adversity prevalence in adults …
