The irreversible degradation of central nervous system function and structure distinguishes neurodegenerative illnesses like Alzheimer's Disease (AD). Alzheimer's disease is characterised by a variety of neuropathologies, including disruptions in neuropsychiatric and cognitive functioning. This illness is the most common neurodegenerative ailment, however there are limited and inadequate therapeutic choices. Because of the less adverse effects associated with their use, plant-based natural medicines are becoming increasingly popular in novel tactics for AD prevention and therapy. Furthermore, their neuroprotective effects target a variety of pathogenic pathways. Alzheimer's disease is a brain ailment that steadily impairs memory and cognitive abilities and, finally, the ability to carry out the simplest tasks. Behavioral disturbances are treated with antidepressants, antipsychotics, mood stabilisers, anxiolytics, and hypnotics. Future approaches in Alzheimer's disease research and therapy include using functional brain imaging techniques in early diagnosis and assessing treatment efficacy and developing new classes of drugs that target distinct neurotransmitter systems. Polyphenols and terpenes are the most prominent secondary plant metabolites because to their wide range of biological activities, including antioxidant, sedative, anti-inflammatory, antibacterial, and enzyme inhibitory properties.
