Summary
Brief summary
Stroke is a strong risk factor for dementia, with up to 80% of individuals having lower cognitive function 5 years after a stroke event. However, having a stroke does not need to result in declining cognition if effective strategies to reduce the risk of post stroke dementia are identified. Diets containing nuts can reduce the risk of both dementia and stroke but have not been tested in stroke survivors. Therefore, this pilot study aims to determine whether eating nuts regularly reduces post-stroke cognitive decline and dementia. The NUT-me pilot study will supplement the diet of stroke survivors with a mix of nuts containing walnuts, hazelnuts, almonds and Brazil nuts for 3 months and assess the effects on cognition and health markers. The researchers predict that regular nut consumption will contribute to preserving post-stroke cognitive function in comparison to patients who do not consume nuts. The results of this novel pilot study will be used to guide a larger trial and provide a simple dietary strategy that stroke survivors can adopt to reduce post-stroke cognitive decline.
