NeuroMark SPECT Template Found Schizophrenia Perfusion Network Differences

TL;DR: A 2026 medRxiv preprint introduced a 68-component NeuroMark template for single photon emission computed tomography (SPECT), a brain blood-flow imaging method, and found schizophrenia-related differences in cerebellar, subcortical, higher-cognition, visual, and triple-network perfusion patterns. Key Findings Template build: Researchers used blind independent component analysis on two large SPECT datasets of 5,001 and 5,000 scans …

Schizophrenia Gut Microbiome Review Found Composition Shifts, Not Richness Loss

TL;DR: A 2026 systematic review and meta-analysis in International Journal of Molecular Sciences found no significant global gut-microbiome alpha-diversity difference in schizophrenia, but reported recurring community-composition and taxonomic shifts. Key Findings 48 studies: The review included 48 human observational studies published between 2017 and 2025. 14 meta-analyzed studies: Only 14 studies provided enough data for …

Schizophrenia MRI Study Found Cortical Network Subtypes

TL;DR: A 2026 preprint on medRxiv used multisite MRI data from 3,958 people with schizophrenia and 5,489 controls to map cortical network disruptions and identify two robust brain-structure subtypes. Key Findings 9,447 MRI participants: The analysis included 3,958 individuals with schizophrenia and 5,489 neurotypical controls from 40 centers. Gradient alterations: Schizophrenia was linked with widespread …

Resting Facial Expressions Differed in Older Adults With MCI-Level Scores

TL;DR: A 2026 preprint on medRxiv found that older adults with mild-cognitive-impairment-level scores showed different resting facial action patterns than healthy controls, especially upper lip raiser, lip tightener, and lip suck measures. Key Findings MCI-level comparison: The study included 45 older adults and compared 31 participants in the MCI-level group with 14 healthy controls. MoCA-defined …

Piano Timbre Changed With Key Movement Motor Control

by
Piano Timbre Changed With Key Movement Motor Control

TL;DR: A 2025 study in PNAS found that expert pianists changed perceived piano timbre by altering specific key-movement features, and listeners could hear intended differences in weight, clarity, and brightness without seeing the performer. Key Findings 20 expert pianists: The performance experiment recruited competition-winning pianists with an average of 25.5 years of professional piano training. …

Parkinson’s Prevention Review Highlights Exercise, Diet, Toxins, and Rehabilitation

by
Parkinson's Prevention Review Highlights Exercise, Diet, Toxins, and Rehabilitation

TL;DR: A 2026 narrative review in Neurological Research and Practice argued that Parkinson’s prevention is most actionable through physical activity, Mediterranean-style diet patterns, toxin reduction, earlier prodromal detection, and better rehabilitation after diagnosis. Key Findings Fastest-growing neurological disorder: The review described Parkinson’s disease as the fastest-growing neurological disorder worldwide. 6.2 to 11.8 million cases: A …

Treatment-Resistant Depression Affected 34% in Pakistan DIVERGE Study

TL;DR: A 2026 preprint in medRxiv found that treatment-resistant depression affected 34% of medication-exposed major-depression patients in Pakistan’s DIVERGE study, with social support and CYP2C19 metabolizer status standing out as locally important treatment-response markers. Key Findings 3,677 eligible patients: The treatment-resistance analysis included adults with major depressive disorder who had medication exposure and enough adherence …

P2X7 Receptors May Link Neuroinflammation to Depression Biology

by
P2X7 Receptors May Link Neuroinflammation to Depression Biology

TL;DR: A 2026 review in Purinergic Signalling argues that ATP-gated P2X receptors, especially P2X7 and P2X4, may connect stress-related neuroinflammation with depression and bipolar-disorder biology. Key Findings P2X7 focus: The review describes P2X7 receptor signaling as a major link between stress, microglial activation, NLRP3 inflammasome signaling, cytokine release, and lower neuroplasticity. P2X4 context: P2X4 receptors …

Olanzapine Anorexia Nervosa Trials Showed Uncertain BMI Gain

TL;DR: A 2026 systematic review and meta-analysis in BMC Psychiatry reported that olanzapine produced a numerically higher body mass index gain in anorexia nervosa trials, but the pooled randomized evidence remained small, heterogeneous, and not statistically significant. Key Findings 7 RCTs included: The review found 7 randomized controlled trials with 152 people treated for anorexia …

Poly-GR Increased Ferroptosis Vulnerability in C9orf72-ALS Cells

by
Poly-GR Increased Ferroptosis Vulnerability in C9orf72-ALS Cells

TL;DR: A 2026 study in Cell & Bioscience found that poly-GR, a toxic repeat protein linked to C9orf72-ALS, pushed motor neuron-like cells toward ferroptosis by raising lipid peroxidation and ferrous iron while weakening the Nrf2/Slc7a11 antioxidant pathway. Key Findings GR50 model: Researchers expressed EGFP-GR50, a 50-repeat glycine-arginine poly-GR construct, in NSC-34 motor neuron-like cells. Ferroptosis …
