A 2026 descriptive study documented 24 major cultural adaptations to the New York University Caregiver Intervention-Enhanced Support (NYUCI-ES) for Chinese and Korean American dementia caregivers. The work is not an outcomes report yet; it is a careful map of how an evidence-based caregiver intervention had to change before it could plausibly fit East Asian immigrant …
A 2026 ADNI/A4 validation study found that Alzheimer’s plasma-biomarker machine-learning models still ranked amyloid PET status well across cohorts, but the practical rule-out number moved hard: negative predictive value fell from 0.831 inside ADNI to 0.644 when the ADNI-trained model was applied to A4.1 Research Highlights 1,707-person ADNI/A4 test: researchers trained amyloid PET prediction models …
Lecanemab blood biomarkers may rebound much faster than amyloid PET after treatment stops: a 2026 PK/PD model estimated that half of the Aβ42/40 treatment effect is lost within 0.5 years, compared with 12.1 years for amyloid PET signal.1 Research Highlights 0.5-year rebound for Aβ42/40: Bhagunde et al. estimated that half of the Aβ42/40 treatment effect …
Some sleep apnea patients stay sleepy even when their CPAP is used 6+ hours a night and apnea events have been driven back to normal range. A 2026 cross-sectional study of 65 PAP-adherent adults found those residually sleepy patients performed measurably worse on global cognition, memory, executive function, attention, and processing speed than their well-rested …
A 2026 TADPOLE modeling study reported that a sequential neural process with normalizing flows predicted future Alzheimer diagnostic stage with mAUC 0.965 ± 0.006, ahead of the authors’ earlier sequential-neural-process model at 0.937 ± 0.014.1 The result is a strong benchmark signal for uncertainty-aware disease-progression AI, but it is still retrospective modeling evidence rather than …
A 2026 Drosophila Parkinson’s model exposed male and female flies to 500 μM rotenone. By 60 days, male flies had worse survival/climbing than female flies; the paper is a vulnerability screen, not evidence that the same genes are ready human biomarkers.1 Research Highlights 500 μM rotenone split male and female flies: Iyer et al. used …
A 2026 Parkinson’s disease study used gene-expression data and genome-scale metabolic modeling to predict patient-level metabolite patterns, then separated 104 patients into 3 metabolic subgroups that were partly reproduced in an independent 81-patient validation dataset. Research Highlights Patient-level modeling found heterogeneity: Abdik et al. predicted secretion tendencies for 802 analyzable metabolites across 104 postmortem substantia …
