Dopamine Tear Sensor Detected Neurological Biomarker Range in Artificial Tears

Dopamine Tear Sensor Detected Neurological Biomarker Range in Artificial Tears

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 …

Davunetide PSP Reanalysis Found Sex-Specific Signals in Women

Davunetide PSP Reanalysis Found Sex-Specific Signals in Women

TL;DR: A 2026 post-hoc reanalysis in Molecular Psychiatry found that women assigned davunetide in a prior 52-week progressive supranuclear palsy trial had more favorable scores on the 10-item PSP Rating Scale (PSPRS-10), daily-living measures, and several cognitive outcomes than women assigned placebo, but the subgroup result needs confirmation in a prospective trial designed to test …

Slackline Training Increased Resting Beta Power and Balance Performance

Slackline Training Increased Resting Beta Power and Balance Performance

TL;DR: A 2026 randomized active-control study in European Journal of Sport Science found that one 45-minute slackline practice session improved eyes-open slackline balance and increased resting-state electroencephalography (EEG) beta power in healthy slackline-naive adults, while eyes-closed balance and tibial somatosensory evoked potentials did not show the same selective change. Key Findings 35-person randomized sample: Researchers …

TBI Apathy Linked to Blunted Reward Prediction Error During Exploration

TBI Apathy Linked to Blunted Reward Prediction Error During Exploration

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 …

People With Dementia Supported AI Medication Reviews With Human Oversight

People With Dementia Supported AI Medication Reviews With Human Oversight

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 …

Watchful Waiting Left Symptoms in 57% of Children With Mild Sleep-Disordered Breathing

Watchful Waiting Left Symptoms in 57% of Children With Mild Sleep-Disordered Breathing

TL;DR: A 2026 study in Journal of Clinical Sleep Medicine found that after 12 months of watchful waiting for mild pediatric sleep-disordered breathing, only 13% of children progressed on polysomnography (PSG), an overnight sleep study, but 57% had persistent or worsening caregiver-reported symptoms. Key Findings 234 observed children: The analysis used the watchful-waiting arm of …

Brain CT Was Normal in 72% of Acute Dizziness Emergency Cases

Brain CT Was Normal in 72% of Acute Dizziness Emergency Cases

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 …

MBCT fMRI Manifolds Shifted During Rumination in Major Depression

MBCT fMRI Manifolds Shifted During Rumination in Major Depression

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: …

EmulatRx Agentic AI Used Real-World Data for Clinical Trial Design

EmulatRx Agentic AI Used Real-World Data for Clinical Trial Design

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. …

Transcriptomic Aging Was Accelerated in Major Depression and Linked to Right Insula Changes

Transcriptomic Aging Was Accelerated in Major Depression and Linked to Right Insula Changes

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 …
