A 2026 developing Human Connectome Project analysis of 438 full-term neonates found that the newborn cortex already had an adult-like folding hierarchy: gyri connected most strongly to other gyri, sulci connected most weakly to other sulci, and structure-function coupling shifted near 41 to 42 weeks postmenstrual age.1 Research Highlights Gyri were already high-connectivity hubs: across …
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 UK Biobank analysis by Aas et al. in BMC Medicine tests the “adversity leaves a fixed biological scar” framing against five biological aging markers in 153,557 middle-aged and older adults — and the marker that moves most reliably isn’t telomere length or any metabolomic clock.1 Research Highlights 153,557-participant test: Aas et al. measured …
A 2026 open-label feasibility trial involving 5 Parkinson’s disease patients found that app-randomized levodopa timing was associated with a mean 4.4-point improvement on the Unified Parkinson’s Disease Rating Scale, but the signal missed conventional statistical significance at p = 0.063.1 The narrow conclusion is feasibility: this was a dosing experiment that justified a blinded controlled …
A 2026 brain tumor prehabilitation study involving 26 surgical patients found that language-targeted non-invasive stimulation plus intensive language training shifted fMRI language activation away from the stimulation target, while measured language and cognition stayed stable. Research Highlights Language-targeted prehabilitation moved the fMRI signal: the group-by-time interaction for stimulation-target overlap was significant, F(1,23) = 4.61, p …
A 2026 iScience metabolomics study found 211 differentially expressed metabolites in migraine patients with patent foramen ovale; in a 220-person validation cohort, lower indoleacrylic acid plus hs-CRP reached AUC 0.722 for distinguishing migraine with PFO from controls.1 Research Highlights Metabolomics found a broad signal: The discovery cohort included 30 migraine-with-PFO patients and 17 controls, with …
