Introduction: Alzheimer disease is a progressive, irreversible brain disorder that slowly destroys memory, thinking, and skills and ultimately the ability to carry out the simplest task. Alzheimer disease involves loss of neurons and synapses in the cerebral cortex and certain subcortical regions. This loss results in gross atrophy of the affected regions, with degeneration in the parietal lobe and, temporal lobe and parts of the frontal cortex and cingulate gyrus.

Methods: We had searched the available literature for original articles on the topic by the accepted and keywords and deduced some concrete evidence through it. 

Conclusion: There are many risk factors for Alzheimer’s disease, which includes an increase in homocysteine levels in the blood, aluminum metal exposure from pots, pans and beverage cans, age, smoking. Identification of risk factors for AD would contribute to the understanding of AD pathogenesis and thus, help in the development of preventive methods.
