Introduction

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. This paper is an annotated bibliography focusing on dementia among older adults and the various results found by public health researchers.

Prevalence of dementia among older patients: A hospital-based study in Iran

This article is based on a study conducted to evaluate the prevalence of dementia and its related features among older hospitalized adults. The authors start by noting that dementia remains a public health hazard in developing countries. To conduct the study, the article illustrates that the authors used a cross-sectional study. The study incorporates 205 elderly participants. The study was also conducted through a social-economic questionnaire, ADL-IAGL scale, mini-mental state analysis, and geriatric depression Scale to come up with their results. According to the authors, these tests and evaluations were conducted to determine various factors that would influence dementia among older adults while taking depression and lifestyle as a major concern.

The article also depicts that 63.4 % of the patient had a normal cognitive function while 36.6 %of the participants indicated some cognitive impairment level. It also indicated a significant relationship between age, the number of their kids, their occupations, and the prevalence of dementia. The data and the research results of this article will help develop statistical arguments through the statistical data collected in their study. The study would help to identify the advancement of dementia among older adults. The data is useful for research purposes and would also help emphasize the need to have mental health check-ups when a patient displays some symptoms, which would also help improve their life quality through quality care.

Alcohol Consumption and risk of dementia and cognitive decline among older adults with or without mild cognitive impairment

This article helps to identify the relationship between the use of drugs such as alcohol and how they are associated with the risks of dementia among older adults. According to the article, older adults have a cognitive decline, and the research would be used to link the decline to alcohol consumption. The authors focus on a study conducted on 3021 research participants aged between 72 years and older. Each of the research participants was linked to alcohol consumption either as high consumers while others were alcoholic but within the recommended units. From the research, the data indicated that the entities consuming alcohol within the recommended units were associated with lower risks of dementia with or without mild cognitive impairment at baseline.

The article will be useful to develop the argument that alcohol consumption has a significant influence on dementia among older adults. The research will be significantly useful to portray how the infrequent higher quantity drinking contributed to the increased rates of dementia among older adults. The study results would also be used to portray how the physicians are caring for the older adults needed to access all the dimensions of the patients drinking behaviors and provide guidance to the entities on alcohol consumption.

Risk factors for incident dementia among older Cubans

This article mainly focuses on the risk factors of dementia in Latin American countries. The research objective was to identify the social demographic, wellbeing, and routine risk influences of incident dementia among the aging adults in Cuba. The authors researched 1846 subjects who had agreed to participate in the study. Each of the participants was presented with a questionnaire, underwent health inspections and cognitive examinations at the baselines. The researchers focused on identifying the association between the risk factors and the incident dementia through logistic regression.

The researchers depict that there are associations between dementia and other issues such as depression, stroke, and low physical activity among the population aging between 65-74 years of age. These entities were associated with dementia. For the entities aging 75 years and above, dementia was linked with low physical activities and smoking. The Article will be significantly useful to develop an argument that a modifiable lifestyle factor plays a crucial role in the development of dementia among older adults.

Illiteracy, dementia risk, and cognitive trajectories among older adults with low education

The authors and the researcher of this article conducted a study investigating whether illiteracy was associated with higher risks of the prevalence and incident dementia and the increased cognitive decline among older adults. The study involved 983 adult participants aged between 63 years and above in a longitudinal community aging study. The article depicts how the researchers, through the study, assessed the effects of literateness on the cognitive courses while modifying appropriate demographics and medical covariates.

The results of the study indicated that illiteracy did not contribute to cognitive decline levels. The article would play a major role to demonstrate how illiteracy was connected to a higher risk of prevalent and incident dementia. However, it would also indicate that there was no more rapid rate of cognitive decline. The data will be useful to link the dementia risk to a lower range of cognitive function.
