Brain-Heart Coupling Tracked Parkinson’s Disease and Freezing of Gait

June 12, 2026 by BrainASAP

TL;DR: A 2026 preprint in medRxiv used electroencephalography (EEG), a scalp electrical-activity recording method, and electrocardiogram (ECG) recordings to test whether brain-heart interplay, meaning coupling between brain-network organization and cardiac autonomic activity, tracks aging, Parkinson’s disease, cognitive screening scores, and freezing of gait. Key Findings Three datasets: Researchers analyzed resting EEG-ECG data from healthy young …

Oxidative Stress Reduced Brain Deubiquitylase Activity With Age

June 12, 2026 by BrainASAP

TL;DR: A 2026 Nature Communications study in aging mouse and killifish brains found that deubiquitylases (DUBs), enzymes that help edit protein-cleanup tags, lost about 40% of their catalytic activity with age even when many of the same enzymes were still present. Key Findings Brain DUB activity fell with age: In old mouse brains, researchers saw …

Mouse Smell Receptors Followed a Spatial Code Linked to Brain Maps

June 11, 2026 by BrainASAP

TL;DR: A 2026 mouse study in Cell found that olfactory receptor neurons, the smell-sensing cells in the nose, were arranged in spatial bands that lined up with matching sensory maps in the brain’s olfactory bulb. Key Findings Organized receptor bands: Researchers found that odor receptor neurons were not randomly scattered across the mouse nose; receptor …

Newborn Metabolomics Linked Prenatal Air Pollution to Autism Risk Pathways

June 11, 2026 by BrainASAP

TL;DR: A 2026 study in Journal of Exposure Science & Environmental Epidemiology linked prenatal PM2.5 and non-freeway NOx exposure with newborn amino-acid metabolism pathways that also tracked autism spectrum disorder (ASD) diagnosis before age 5. Key Findings 100 newborn blood spots: Researchers analyzed 50 children later diagnosed with ASD and 50 matched controls from Kaiser …

Machine Learning Predicted Mindfulness App Engagement in Generalized Anxiety Disorder

June 11, 2026 by BrainASAP

TL;DR: A 2026 study in Journal of Affective Disorders used interpretable machine learning to predict who completed more prompts during a 14-day mindfulness app trial for generalized anxiety disorder. Key Findings Trial size: A two-arm randomized trial included 110 people with generalized anxiety disorder, assigned to a mindfulness ecological momentary intervention or a self-monitoring app. …

Maternal COVID Immune Signatures Were Linked to Infant Neurodevelopmental Screening Risk

June 11, 2026 by BrainASAP

TL;DR: A 2026 Communications Biology study associated maternal SARS-CoV-2 infection during pregnancy with more positive toddler autism-risk screens and newborn immune-protein patterns tied to nicotinamide metabolism, microglial activation, and neutrophil activity. Key Findings Positive M-CHAT-R/F screens, a toddler autism-risk screening result, occurred in 10.1% of 218 SARS-CoV-2-exposed children versus 5.7% of 527 pre-pandemic controls. Earlier …

Major Upper-Limb Amputation Linked to Higher Mental Health Diagnoses

June 11, 2026 by BrainASAP

TL;DR: A 2026 retrospective database study in Archives of Orthopaedic and Trauma Surgery found that people with major upper-extremity amputations had higher one-year rates of new mental-health diagnoses, antidepressant starts, and psychotherapy use than matched patients with minor hand or digit amputations. Key Findings Matched database study: Researchers compared 1,226 major upper-extremity amputation patients with …

Loneliness Linked Alzheimer’s Disease and Suicide Risk Signals

June 11, 2026 by BrainASAP

TL;DR: A 2026 systematic review and meta-analysis in Psychogeriatrics linked loneliness with Alzheimer’s disease and several forms of suicidal behavior, with especially strong shared correlations for hopelessness, insomnia, entrapment, and stress. Key Findings 316 studies reviewed: Researchers found 44 studies on loneliness and Alzheimer’s disease, 261 on loneliness and suicide, and no original study that …

GLP-1 Receptor Agonists Linked to Small Hypersomnolence Risk Increase

June 11, 2026 by BrainASAP

TL;DR: A 2026 real-world cohort study in Journal of Diabetes & Metabolic Disorders linked GLP-1 receptor agonists, drugs targeting a glucose-related metabolic hormone pathway, to a higher hazard of new hypersomnolence, but the absolute risk increase was small. Key Findings 237,986 matched patients: The TriNetX analysis compared 118,993 GLP-1 receptor agonist users with 118,993 matched …

Frontal Midline Theta Linked Negative Emotionality to Weaker Cognitive Control

June 10, 2026 by BrainASAP

TL;DR: A 2026 study in Cognitive, Affective, & Behavioral Neuroscience found that lower frontal midline theta, an EEG marker of cognitive-control engagement, partly explained why young adults with higher negative emotionality performed worse on a Go/No-Go inhibition task. Key Findings 106 young adults completed EEG testing: U.S. Army National Guard recruits performed a Go/No-Go task …
