Background and Aims: Dementia is the loss of cognitive functioning – remembering, thinking, and reasoning – and behavioral capabilities to such a degree that it interferes with an individual's daily living activities. The objective of this paper is to summarize current knowledge on the most promising interventions for preventing cognitive decline. Methods: Electronic databases were searched using PubMed/Medline and Google Scholar to retrieve relevant research papers conducted in Saudi Arabia and internationally. Keywords included “dementia,” “prevention strategies,” “aging,” “aged,” “Elderly population.” Articles published in the English language and published between 2000 and 2018 were included in the study. Analysis: Overall, limited evidence exists to support the cause-effect association between the progression/development of dementia and preventative strategies. Studies to date provide the most promising strategies for dementia prevention that includes healthy diet, social engagement, physical activity, cognitive activity, and vascular risk factor control. Conclusion: Dementia is a disease more commonly observed in old people. Studies in the future will determine the risk factor modification and its implications in controlled trials with specific emphasis on whether some simultaneous interventions may either have a multiplicative or additive effect.
