Alzheimer's disease (AD) is the most common form of dementia and has become a growing health concern in aging societies. β‑amyloid (Aβ) formation in vulnerable brain regions, such as the hippocampus and cerebral cortex is a major neuropathological feature of the disease. Currently, there is no specific drug available for the treatment of AD. However, due to its high antioxidant activity, aged garlic extract (AGE) has been widely used to prevent chronic diseases, such as cancer and cardiovascular disease. A number of studies on the benefits of AGE against cognitive and memory deficits have also been published. This review aimed to summarize the information related to the effects of AGE on learning memory in order to obtain a better understanding of its mechanisms of action. This review also presents an overview of the pathogenesis of AD, and summarizes the main ingredients and neuroprotective effects of AGE against cognitive and learning memory deficits. The mechanisms of action of AGE are also discussed.
