**6. Ginger's memory-boosting properties**

As the population ages, aging-induced cognitive impairment is recognized as a prodromal stage of dementia that affects the quality of life of older people [60, 61]. Then, in order to slow the course of dementia, researchers may need to look into interventions that improve memory function. Ginger improved memory function in aging-related disorders, according to a clinical trial by Saenghong et al. [62]. They tested middle-aged women's working memory and cognitive function after giving them ginger extract orally, and found that the ginger treatment increased scores in word recognition, digit vigilance, choice reaction, arithmetic working memory, and spatial working memory significantly. Ginger treatment improved memory in normal mice via increasing hippocampus levels of nerve growth factor (NGF), which activates extracellular signal–regulated kinases (ERK) and then cAMP response element– binding protein (CREB), resulting in increased synaptogenesis [63–65]. In these investigations, ginger was found to help with cognitive decline in the early stages of dementia in the elderly.
