Key result
Exercise provides the strongest evidence for preventing elderly cognitive decline, while diabetes and cholesterol modifications fail.
Why the study?
Vascular risk factors are considered significant targets for cognitive decline prevention, but the quantity and quality of evidence in the elderly needed evaluation.
Does controlling cardiovascular risk factors prevent cognitive decline in the elderly?
Systematic Review
Does controlling cardiovascular risk factors prevent cognitive decline in the elderly?
Exercise and physical activity show the most positive evidence for preventing cognitive decline in the elderly, whereas control of diabetes, cholesterol, and hypertension currently lack robust positive evidence.
Exercise should be prioritized to prevent cognitive decline in the elderly; challenges broad CV risk-factor control and leaves open targeted trials on diabetes and lipids.
With the increasing proportion of the elderly population, neurodegenerative diseases such as dementia are becoming more prevalent worldwide. Vascular risk factors are considered significant targets for cognitive decline prevention. We reviewed the effect of cardiovascular risk factors on cognitive decline prevention in the elderly to evaluate the quantity and quality of evidence in managing the elderly population with cognitive decline. Data analysis was available from 25 studies that explored the effects of controlling cardiovascular risk factors on the risk of cognitive impairment. These risk factors include diabetes mellitus, high blood pressure, high cholesterol levels, and exercise and physical activity. The most positive evidence was found for exercise and physical activity. On the other hand, diabetes mellitus and cholesterol modifications showed no positive impact on cognitive function. Studies on hypertension control were incongruous. There is a need for large-sample, robust randomized clinical trials to provide sufficient evidence for the modification of various cardiovascular risk factors in preventing cognitive decline.

Noroozıan et al. (2022) conducted a systematic review in Cognitive decline. Controlling cardiovascular risk factors (diabetes, hypertension, cholesterol, exercise) was evaluated on Cognitive decline prevention. Exercise and physical activity showed the most positive evidence for preventing cognitive decline in the elderly, whereas diabetes and cholesterol modifications showed no positive impact.
