Severe Infections Predicted Dementia After 27 Comorbidities in Finland

by GLOOM

MHD featured image for severe infections, comorbidity, and dementia risk.

A nationwide Finnish registry study found that 2 severe infection categories still predicted dementia after adjustment for 27 noninfectious comorbid diseases.1 Cystitis and bacterial infection of an unspecified site both had adjusted rate ratios of 1.19 after comorbidity adjustment, meaning the infection-dementia association did not disappear when prior hospital-treated illnesses were modeled. Research Highlights The …

Alzheimer’s Plasma Protein Structure Panel Reached AUCs Above 0.93

by GLOOM

MHD featured image for Alzheimer's plasma protein-structure biomarkers.

A 2026 Nature Aging study involving 520 participants found that plasma protein-structure signatures classified healthy control, mild cognitive impairment, and Alzheimer’s disease groups with 83.44% three-way accuracy.1 The result is a serious biomarker signal, but it is not a clinic-ready replacement for established Alzheimer’s testing. Research Highlights Classification was strong: The plasma structural-proteomics panel reached …

SPP1 Marks Cross-Disease Microglial Activation in Neurodegeneration

by GLOOM

MHD featured image for SPP1 microglia and neurodegeneration transcriptomics.

A 2026 Glia analysis found a shared microglial transcriptional program across 5 neurodegenerative contexts: ALS, frontotemporal dementia, Alzheimer’s disease, aging, and Parkinson’s disease.1 The standout marker was SPP1, a gene encoding osteopontin, but the finding is a cellular-state signal rather than a ready diagnostic test. Research Highlights Cross-disease microglia converged: the integrated dataset covered ALS, …

Amitriptyline Water Pollution Impaired Male Guppy Spatial Accuracy

by GLOOM

MHD featured image for amitriptyline water pollution and guppy spatial cognition.

A 2026 Environmental Science & Technology experiment found that wild guppies still reduced maze solve times with practice after 11-day exposure to environmentally motivated amitriptyline concentrations, but exposed males made 26.35% to 34.21% more navigation errors than control males.1 The result is a sex-specific accuracy signal, not a blanket claim that antidepressant pollution erased learning. …

Image Memorability, Not Recognition Success, Drove N400 Encoding Signals

by GLOOM

MHD featured image for image memorability and N400 EEG signals.

A 2026 EEG study found that image memorability predicted recognition strongly, z = 9.17, p < 0.001, and the N400 encoding signal tracked memorability after later recognition success was included in the same model.1 The result weakens the common shortcut that every hit-vs-miss brain signal is purely an encoding-success signal. Research Highlights Memorability predicted recognition: …

Depression Brain Energy Landscape Showed State 3 Trapping in MDD

by GLOOM

MHD featured image for depression brain energy landscape state trapping.

A 76-person Nature Communications fMRI study found that people with major depressive disorder spent a higher share of time in a model-derived State 3 than healthy controls, 27.63 vs. 25.65, p(FDR) = 0.035, and State 3 occupancy correlated with QIDS depression severity, r2 = 0.268, p(FDR) = 0.008.1 The result points to altered brain-state transitions …

Opioid Coalitions Used Data and Shared Goals to Expand MOUD/Naloxone

by GLOOM

MHD featured image for opioid coalitions and MOUD/naloxone implementation.

A 2026 qualitative case study of 8 top-performing HEALing Communities Study communities linked opioid-response implementation success to representative coalition membership, shared goals, data connectivity, and communications campaigns, not to a simple urban-vs.-rural split.1 The useful lesson is operational: coalitions worked when collaboration was turned into service reach for medication for opioid use disorder and overdose …
