Biomarkers.

Background: In Alzheimer's disease, Aβ triggers tau spreading which drives neurodegeneration and cognitive decline. However, the mechanistic link between Aβ and tau remains unclear, which hinders therapeutic efforts to attenuate Aβ-related tau accumulation. Preclinical research could show that tau spreads across connected neurons in an activity-dependent manner, and Aβ was shown to trigger neuronal hyperactivity and hyperconnectivity.

Background: In Alzheimer's disease, Aß triggers tau spreading which drives neurodegeneration and cognitive decline. However, the mechanistic link between Aß and tau remains unclear, which hinders therapeutic efforts to attenuate Aß-related tau accumulation. Preclinical research could show that tau spreads across connected neurons in an activity-dependent manner, and Aß was shown to trigger neuronal hyperactivity and hyperconnectivity.

Patient activation improves with a multi-component personalized mHealth intervention in older patients at risk of cardiovascular disease: a pilot randomized controlled trial.

Aims: This study aimed to determine the effect of a multi-component mHealth intervention on patient activation and examine its predictors among older adults at risk of cardiovascular disease (CVD).

Methods And Results: This pilot randomized controlled trial compared two groups: Get FIT (control), who received healthy lifestyle counselling from a licensed health coach, a mHealth app (MyFitnessPal) with push alerts, and an activity tracker, and Get FIT + (intervention), who received the same interventions and had personalized text messages with 3- and 6-month follow-up periods. Patient activation was measured using the 13-item Patient Activation Measure; higher scores indicated better activation.
