Decanoic acid, an MCT dietary component, alleviates cognitive impairment, cellular senescence, and promotes autophagy in accelerated aging and neurotoxic mouse models induced by chronic administration of D-galactose and D-galactose/AlCl₃.

ABSTRACT:

Introduction

Cognitive decline advances with age, increasing the risk of dementia and Alzheimer's disease among older adults. Medium-chain triglyceride (MCT) ketogenic diets have shown potential in slowing down age-related cognitive decline; however, the exact neuroprotective roles of MCT components, specifically decanoic acid and octanoic acid, remain unclear.

Methods

Swiss Albino mice were subjected to D-galactose to trigger accelerated aging, or to a combination of D-galactose and aluminium chloride to mimic Alzheimer's disease-like neurotoxicity. The animals received treated with decanoic acid, octanoic acid, or both. Cognitive function was assessed using the Morris water maze, while brain tissues were examined for oxidative stress markers, autophagy indicators, senescen
