VOLUME | DEC 2022 Arrhythmia and Cognitive Decline: Insights from Low-Educational Level Elderly Individuals in Taiwan

Imagine your brain is a fancy clock, ticking away smoothly, keeping track of time. But what if the gears start glitching? Arrhythmia, a condition where the heart beats irregularly, might be more than just a problem for your ticker. Recent research suggests that arrhythmia could also pose a risk for dementia, depending on various factors like age, race, and education level. In Taiwan, a study involving elderly individuals with low educational levels found that those with arrhythmia had an increased risk of developing dementia. Interestingly, this association was stronger among older patients with mild cognitive impairment (MCI). For younger MCI patients, taking anti-hypertensive drugs appeared to lower the risk of dementia. In addition, being male and having a higher educational level were linked to a higher risk of dementia in younger MCI patients. The study also revealed that coronary heart disease and symptoms of depression were associated with an elevated risk of cognitive decline among cognitively unimpaired individuals. These findings suggest that arrhythmia and other modifiable risk factors could serve as potential indicators for predicting the onset of dementia in clinical settings, particularly for individuals with low educational levels.

IntroductionThere is increasing evidence that arrhythmia is a risk factor for dementia; however, it appears that arrhythmia affects the cognitive function of individuals differentially across age groups, races, and educational levels. Demographic differences including educational level have also been found to moderate the effects of modifiable risk factors for cognitive decline.MethodsThis study recruited 1,361 individuals including a group of cognitively unimpaired (CU) individuals, a group of patients with mild cognitive impairment (MCI), and a group of patients with dementia with low education levels. The participants were evaluated in terms of modifiable risk factors for dementia, including arrhythmia and neuropsychiatric symptoms.ResultsCox proportional hazard regression models revealed that among older MCI patients (>75 years), those with arrhythmia faced an elevated risk of dementia. Among younger MCI patients, those taking anti-hypertensive drugs faced a relatively low risk of dementia. Among younger MCI patients, male sex and higher educational level were associated with an elevated risk of dementia. Among CU individuals, those with coronary heart disease and taking anti-lipid compounds faced an elevated risk of MCI and those with symptoms of depression faced an elevated risk of dementia.DiscussionThe risk and protective factors mentioned above could potentially be used as markers in predicting the onset of dementia in clinical settings, especially for individuals with low educational levels.
