Medulloblastoma Radiotherapy Changed Language fMRI Networks 80.7%

by GLOOM

MHD featured image for medulloblastoma radiotherapy and language fMRI network changes.

A 2026 preprint involving 31 children and adolescents treated for medulloblastoma found that silent verb-generation fMRI separated pre- from post-radiotherapy scans with 80.7% leave-one-subject-out accuracy (p = 0.0149).1 The signal points to early cerebellar-cerebral language-network change, not yet to a proven long-term cognitive endpoint. Research Highlights Classifier performance was above chance: A linear support-vector machine …

FTL1 Iron Protein Reversal Improved Cognitive Aging in Old Mice

by GLOOM

MHD featured image for FTL1, iron biology, and cognitive aging in mice.

A 2025 Nature Aging study found that hippocampal ferritin light chain 1 (FTL1) rose with age in mouse neurons, tracked poorer cognition, and became experimentally reversible in old mice. This is an animal-mechanism result, not a human anti-aging treatment.1 Research Highlights FTL1 rose in aged hippocampus: Western blot data showed higher hippocampal FTL1 in aged …

Teen Emotion-Regulation Profiles Predicted Anxiety and Depression

by GLOOM

A 2026 longitudinal study involving 951 adolescents found 5 emotion-regulation profiles, not the 3-profile structure the researchers expected, and the clearest mental-health separation came from the adaptive and maladaptive profiles.1 Teen coping looked less like a single good-versus-bad scale and more like a pattern of motives, strategies, and beliefs about whether those strategies work. Research …

PReDicT Antidepressant Algorithm Cost-Effectiveness Was Uncertain

by GLOOM

MHD featured image for PReDicT antidepressant algorithm cost-effectiveness.

A 913-person economic evaluation of the PReDicT antidepressant algorithm found nearly identical EQ-5D quality-of-life gains vs. treatment as usual (+0.139 vs. +0.140) and nearly identical societal cost reductions (−€2,589 vs. −€2,602), while cost-effectiveness probabilities were only 46% to 59% at trial level but exceeded 80% in the UK.1 The algorithm signal was country-specific and capability-weighted, …

C9orf72 ALS/FTD Inflammation Linked to Microbial Glycogen in Gut

by GLOOM

MHD featured image for C9orf72, microbial glycogen, gut inflammation, and ALS/FTD risk.

A Cell Reports study tied C9orf72-related ALS/FTD inflammation to a gut-bacterial product: inflammatory microbial glycogen appeared in 15 of 22 ALS fecal samples, 1 of 1 C9orf72-frontotemporal dementia sample, and 4 of 12 healthy controls.1 The result supports a narrower gene-by-microbial-product mechanism that makes C9orf72 loss of function more inflammatory. Research Highlights Human samples carried …

GLP-1 Drugs Reduced Sleep Apnea AHI by 13.89 Events per Hour

by GLOOM

MHD featured image for GLP-1 receptor agonists reducing sleep apnea severity and weight.

A 2026 meta-analysis of 4 randomized trials found that GLP-1 receptor agonists reduced obstructive sleep apnea severity by 13.89 apnea-hypopnea events per hour compared with placebo, alongside 12.46 kg more weight loss than placebo.1 The effect looks clinically meaningful for obesity-linked sleep apnea, but high heterogeneity means the result should not be flattened into “GLP-1 …

Post-Stroke Deep Gray Nuclei MRI Predicted 3-Month Recovery

by GLOOM

MHD featured image for post-stroke deep gray nuclei MRI and recovery prediction.

A 2026 automated MRI analysis of 153 adults with first cortical middle cerebral artery stroke found that remote deep gray nuclei changes were already measurable within 21 days, and 2 asymmetry markers independently predicted 3-month disability change: putamen volume Z-score asymmetry (β = −0.24; p = 0.021) and thalamic apparent diffusion coefficient asymmetry (β = …
