This review involves discussing the various causes, pathophysiology, modifiable and non-modifiable risk factors associated with this increasing cognitive deterioration in elderly people, di-agnostic criteria, and preventive methods. This review will help in better understanding of the cognitive im-pairment in elderly people. Better understanding of the disease helps in better treatment modalities.
