Cognitive ability is the most crucial modifiable and effective aspect of the quality of life for the elderly population. The aging process affects processing speed, and substantial interindividual differences distinguish a person’s cognitive ability. Based on existing knowledge, aging and cognitive decline are clearly not inevitable. Traditional expertise suggests that Bacopa monnieri (B monnieri) (BM), a neural tonic in Ayurvedic medicine, enhances mental performance, intelligence, and memory. Therefore, this review article focuses on BM’s investigation into manageable medical comorbidities affecting cognitive function. This review is based on research studies indexed in Scopus, Science Direct, PubMed, and Google Scholar databases. B monnieri improves dementia, learning, and memory by reducing inflammation and oxidative stress levels, and could also enhance spatial and working memory impairment. B monnieri is suggested as an augmentation therapy for memory enhancement, which helps to improve attention, neural networks, long-term potentiation, and language function in daily tasks such as driving, navigating, climbing stairs, remembering numbers, and so on.
