Imagine a complex web, with each strand representing a different aspect of cardiovascular health, like hypertension and diabetes. Now imagine that web intertwined with another intricate network representing cognitive function in the elderly. This study utilized network analysis to delve into this twisted tapestry, specifically focusing on the impact of vascular factors such as cerebrovascular disease and coronary heart disease on cognitive function. The findings showed that these two diseases had a profound effect on cognitive domains, with cerebrovascular disease impacting memory and spatial orientation, while coronary heart disease affected memory, executive function, attention, and more. Furthermore, comparisons with a control group further emphasized the differences in network structure and connection strength. By better understanding these connections, we can enhance cognitive screening accuracy, develop personalized intervention strategies, and gain insights into the underlying mechanisms of cognitive decline in individuals with vascular diseases.
IntroductionCognitive decline in the elderly population is a growing concern, and vascular factors, such as hypertension, diabetes, cerebrovascular disease, and coronary heart disease, have been associated with cognitive impairments. This study aims to provide deeper insights into the structure of cognitive function networks under these different vascular factors and explore their potential associations with specific cognitive domains.MethodsCognitive function was assessed using a modified Chinese version of the mini-mental state examination (MMSE) scale, and intensity centrality and side weights were estimated by network modeling. The network structure of cognitive function was compared across subgroups by including vascular factors as subgroup variables while controlling for comorbidities and confounders.ResultsThe results revealed that cerebrovascular disease and coronary heart disease had a more significant impact on cognitive function. Cerebrovascular disease was associated with weaker centrality in memory and spatial orientation, and a sparser cognitive network structure. Coronary heart disease was associated with weaker centrality in memory, repetition, executive function, recall, attention, and calculation, as well as a sparser cognitive network structure. The NCT analyses further highlighted significant differences between the cerebrovascular disease and coronary heart disease groups compared to controls in terms of overall network structure and connection strength.ConclusionOur findings suggest that specific cognitive domains may be more vulnerable to impairments in patients with cerebrovascular disease and coronary heart disease. These insights could be used to improve the accuracy and sensitivity of cognitive screening in these patient populations, inform personalized cognitive intervention strategies, and provide a better understanding of the potential mechanisms underlying cognitive decline in patients with vascular diseases.
