DEMENTIA Dementia: Annotated Bibliography Shaunglazier

Dementia is a chronic disease that is prevalent among older adults. Dementia is not a solitary illness in itself. It is a general terminology that depicts various symptoms of memory impairments, communication, and thinking. The most common symptom of dementia is forgetfulness. Dementia is a syndrome under which there is deterioration in memory, affecting the person's ability to perform daily tasks.

Prevalence of Dementia among Older Patients

This article is based on a study conducted to evaluate the prevalence of dementia and its related features among older hospitalized adults. The authors note that dementia remains a public health hazard in developing countries. The study incorporates 205 elderly participants and used a social-economic questionnaire, ADL-IAGL scale, mini-mental state analysis, and geriatric depression scale to reach its conclusions. The results indicated that 63.4% of the patients had normal cognitive function while 36.6% indicated some level of cognitive impairment. There was a noted significant relationship between age, number of children, occupations, and the prevalence of dementia. This data aids in emphasizing the need for regular mental health check-ups for older adults showing symptoms, which can significantly improve their quality of life through adequate care.

Alcohol Consumption and Dementia Risk

This article explores the relationship between alcohol consumption and the risks of dementia among older adults. A study involving 3,021 participants aged 72 years and older was conducted. It was discovered that those consuming alcohol within recommended units faced lower risks of dementia, whether or not they had mild cognitive impairment at the baseline. The findings emphasize the need for physicians to assess the alcohol consumption patterns of older adults and provide appropriate guidance. Higher infrequent drinking was correlated with increased rates of dementia among older populations, indicating the importance of understanding the implications of alcohol-related behaviors.

Risk Factors for Incident Dementia Among Older Cubans

This article investigates the risk factors contributing to dementia among aging adults in Cuba. Researchers examined 1,846 subjects, utilizing questionnaires alongside health inspections and cognitive assessments. The study identified associations between dementia and issues common in older demographics, such as depression, stroke, and low physical activity, particularly in individuals aged 65-74. Among those aged 75 and older, low physical activity and smoking were significant risk factors. The findings underscore the influence that modifiable lifestyle factors have on dementia development, emphasizing the need for interventions targeting these areas.

Illiteracy and Cognitive Decline

This research examined whether illiteracy was associated with an increased risk of dementia and rapid cognitive decline in older adults. The longitudinal community aging study involved 983 participants aged 63 and older. While the study found that illiteracy correlated with a higher risk of prevalent and incident dementia, it did not indicate an accelerated rate of cognitive decline due to illiteracy. These results contribute to understanding the risk landscape for dementia, suggesting that while literacy may influence dementia prevalence, it is not necessarily a direct factor in the rate of cognitive decline.

Conclusion

This annotated bibliography has synthesized various studies addressing dementia among older adults, revealing intricate relationships between lifestyle choices, demographic factors, and cognitive health. Continued research in this field remains critical, particularly to identify avenues for effective public health interventions aimed at improving quality of life and reducing dementia-related risks among aging populations.
