In the 21st century, the human population is suffering from a neurodegenerative disorder in which neuronal death occurs due to a long-term chronic condition causing substantial major health concerns. When neurons die, they are not regenerated, causing cognitive impairment, i.e., Alzheimer’s disease, Parkinson’s disease, schizophrenia, and dementia. This review concentrates only on Alzheimer’s disease aetiology and various plants having potent neuroprotective activity related to Alzheimer’s disease. The most common aetiology of Alzheimer’s disease is a deposition of APP protein, hyperphosphorylation of Tau protein, a reduction in acetylcholine and oxidative stress, which are discussed briefly. Moreover, pertinent evidence is also discussed for medicinal plants with potent or promising neuroprotective activity related to Alzheimer’s disease.
