Among Swedish memory-clinic patients without dementia, more stressful life events were linked to a spinal-fluid sign of Alzheimer’s amyloid buildup, but only in people with moderate-to-high insomnia symptoms, according to a 2026 study.1 Research Highlights Stress and insomnia worked together: in 103 patients with spinal-fluid tests, lifetime stressful events and insomnia symptoms interacted in relation …

A 2026 humanized P301S tauopathy mouse study found that syntaxin-6 knockout partly rescued early motor impairment from months 1 to 4, protected gait at 5.5 months, reduced frailty (p = 0.0052), and reduced superficial-cortex neurodegeneration at 3 months (p = 0.0055).1 The finding strengthens syntaxin-6 as a tauopathy modifier, but it is still mouse genetics, …
