AI Identified CgA-KO/PS19 Mouse Model of Asymptomatic Alzheimer’s Resilience

AI Identified CgA-KO/PS19 Mouse Model of Asymptomatic Alzheimer’s Resilience

TL;DR: A 2026 study in Acta Neuropathologica Communications used Boolean-network AI analysis of Alzheimer’s RNA-seq data to identify a 40-gene disease signature and validate CgA-KO/PS19 mice as a model of asymptomatic Alzheimer’s-like resilience. Key Findings 289-person training set: Boolean Network Explorer was trained on cortical RNA-seq data from 70 cognitively normal controls and 219 Alzheimer’s …

Psychosis in Lupus Linked to Immune Disease Activity in Review

Psychosis in Lupus Linked to Immune Disease Activity in Review

TL;DR: A 2026 systematic review and meta-analysis in Lupus found that psychosis affected about 4.5% of adults with systemic lupus erythematosus (SLE), was more common in neuropsychiatric SLE, and tracked most strongly with active immune disease markers rather than serving as a stand-alone psychiatric label. Key Findings Sixty-five studies were included: The review covered 31,495 …

Head Impact MEG Changes Mapped to Neurochemical Brain Systems

Head Impact MEG Changes Mapped to Neurochemical Brain Systems

TL;DR: A 2026 preprint in medRxiv found that head-impact-related magnetoencephalography (MEG) changes in high-school football players were strongest in cortical regions matching specific neurotransmitter and gene-expression maps, especially norepinephrine, nicotinic acetylcholine, APOE, and BDNF-related patterns. Key Findings MEG tracked pre-to-post-season brain signaling across 278 timepoints from 91 male high-school football players. Concussion-related cortical slowing aligned …

fMRI Noise Signal Tracked Nicotine Craving and Stimulant Effects

fMRI Noise Signal Tracked Nicotine Craving and Stimulant Effects

TL;DR: A 2026 study in Biological Psychiatry: Global Open Science found that systemic low-frequency oscillation (sLFO), a slow whole-body physiology readout usually treated as functional MRI noise, tracked nicotine dependence, cue-induced craving, abstinence, and stimulant-related task performance across four fMRI cohorts. Key Findings The study analyzed four fMRI cohorts: Researchers examined a 64-person cigarette cue-reactivity …

Early Psychosis Linked to Work and Education Disruption in SEEearly Cohort

Early Psychosis Linked to Work and Education Disruption in SEEearly Cohort

TL;DR: A 2026 study in European Archives of Psychiatry and Clinical Neuroscience found that more than half of 184 young adults entering an early-psychosis supported employment and education trial were not in work, school, or training, even though nearly all had finished at least lower- or upper-secondary schooling. Key Findings The SEEearly cohort included 184 …

Blood miRNAs Linked to Hippocampal Volume and Brain Atrophy

Blood miRNAs Linked to Hippocampal Volume and Brain Atrophy

TL;DR: A 2026 Molecular Psychiatry study linked blood-derived microRNAs, short RNA regulators that help control gene expression, to left hippocampal volume and later brain atrophy in adults from the Rhineland Study. Key Findings Baseline MRI cohort: Researchers compared blood microRNA expression in 2,062 adults with baseline MRI measures of left and right hippocampal volume, hippocampal …

Youth Cannabis Use Linked to Flatter Cognitive Development

Youth Cannabis Use Linked to Flatter Cognitive Development

TL;DR: A 2026 Neuropsychopharmacology study of 11,036 ABCD participants found youth who initiated cannabis use showed flatter cognitive-development trajectories from ages 9 to 17, with hair-detected THC linked to worse episodic-memory change. Key Findings 11,036 youth were followed: Researchers used the Adolescent Brain Cognitive Development (ABCD) Study to track neurocognitive performance from late childhood into …

Visual Distraction Strengthened the Oblique Effect in Working Memory

Visual Distraction Strengthened the Oblique Effect in Working Memory

TL;DR: A 2026 study in Cognitive, Affective, & Behavioral Neuroscience found that visual working memory, the short-term holding of visual details, still showed a strong cardinal-versus-diagonal orientation bias under distraction, while transcranial direct current stimulation (tDCS), a weak noninvasive brain-stimulation method, did not improve task reports. Key Findings Two stimulation experiments tested orientation memory: Researchers …

UK Perinatal Lithium Prescribing Was Rare and Often Interrupted

UK Perinatal Lithium Prescribing Was Rare and Often Interrupted

TL;DR: A 2026 cohort study in The British Journal of Psychiatry found that lithium prescribing around pregnancy was rare in UK primary care records, and most pre-pregnancy lithium users did not stay on treatment through all three trimesters. Key Findings 752,112 pregnancies analyzed: Researchers used UK Clinical Practice Research Datalink GOLD records from 1995 to …

Rotenone Parkinson’s Fly Model Showed Sex-Specific Gene Responses

Rotenone Parkinson's Fly Model Showed Sex-Specific Gene Responses

TL;DR: A 2026 fly study in IBRO Neuroscience Reports found that long-term rotenone exposure produced stronger survival, climbing, oxidative-stress, and late immune-gene disruption in male Drosophila than in female flies. Key Findings 90 flies per sex were tracked: Survival assays used three sets of 30 male or female flies after rotenone feeding. Two disease windows …
