TL;DR
This study explores whether alpha-lipoic acid can help treat early brain damage caused by alcohol in rats, comparing it to two other drugs.
Contribution
This is the first study to compare alpha-lipoic acid with rivastigmine and memantine in treating early-stage alcohol-related brain damage in rats.
Findings
Alpha-lipoic acid improved memory and reduced Purkinje cell damage in alcohol-treated rats.
Alpha-lipoic acid decreased lipid peroxidation by 44%, more effectively than the other drugs.
Alpha-lipoic acid also reduced superoxide dismutase activity by 33%, similar to the reference drugs.
Abstract
Alcohol misuse can lead to alcohol-related brain damage (ARBD), a condition linked to long-term cognitive impairment and considerable disease burden. The pharmacological characteristics of alpha-lipoic acid (ALA) make it a promising candidate for the treatment of ARBD. In this study, adult male Wistar rats were divided into eight experimental groups. Four groups received a 20% (v/v) ethanol–tap water solution ad libitum for 15 weeks to induce early-stage ARBD, while the remaining received only tap water. After 14 weeks, all groups were administered daily injections for one week with either ALA, rivastigmine, or memantine. Behavioral testing included the step-through passive avoidance and rotarod performance tests. Whole-brain biochemical analyses assessed acetylcholinesterase activity, brain-derived neurotrophic factor, and oxidative stress biomarkers. Brain weight, relative brain…
