Alzheimerʼs disease (AD) is the most common form of dementia, associated with irreversible neuropathological and neurobehavioral changes accompanied by memory and cognitive impairments. Despite the overwhelming evidence that links oxidative stress and AD, antioxidant therapies have limited success in clinical trials. The present study was aimed to evaluate the protective effect of Chia seeds extract on aluminum chloride (AlCl3) induced rat model. Oral administration of AlCl3 (200 mg/kg) for 60 days significantly elevated the levels of aluminum (Al), activity of acetylcholinesterase (AChE) and protein expressions of amyloid precursor protein (APP) compared to control group in hippocampus and cortex of rat brain. Chia seeds extract was administrated orally along with AlCl3 for 60 days (day after day protocol), significantly revert the Al concentration, AChE activity and Ab synthesis-related molecules in the studied brain regions. Our results showed that the behavioral impairments caused by aluminum were significantly attenuated by Chia seeds extract. As the spontaneous locomotor and exploratory activities in open field test were significantly reduced and the learning and memory impairments in Novel Object Recognition (NOR) test were enhanced. The histopathological studies in the hippocampus and cortex of rat brain also supported that Chia seeds extract markedly reduced the toxicity of AlCl3 and preserved the normal histoarchitecture pattern of the hippocampus and cortex. From these results, it is concluded that Chia seeds can reverse memory loss caused by aluminum intoxication through attenuating AChE activity and amyloidogenic pathway.
