Alzheimer's Disease Prevalence and Effects in American Women
This paper examines the prevalence and effects of Alzheimer's disease among American women through an annotated bibliography of peer-reviewed research. With over 5 million cases in the United States and two-thirds of those affecting women, Alzheimer's disease represents a disproportionate burden on the female population. The paper explores contributing factors including biological sex differences, hormonal influences, nutritional status, and social determinants of health such as socioeconomic status and education. Particular attention is given to racial and ethnic disparities, especially among African American and Hispanic women. Each annotated source is evaluated for its purpose, key findings, strengths, and limitations, providing a foundation for future dissertation research on this topic.

What makes this paper effective
- Each annotated entry follows a consistent structure — problem, purpose, findings, and limitations — making the bibliography easy to navigate and compare across studies.
- The introduction grounds the research in a specific and timely public health context, clearly justifying why women represent a distinct and underexplored population for Alzheimer's research.
- The paper addresses intersectionality effectively by acknowledging racial and ethnic disparities (African American and Hispanic women) alongside biological and social factors, adding depth to the analysis.
Key academic technique demonstrated
This paper demonstrates the annotated bibliography format at a graduate level, moving beyond simple summaries to critically evaluate each source's methodology, findings, applicability, and limitations. This technique signals a researcher's ability to assess the quality and relevance of evidence before constructing a larger argument — an essential skill in dissertation preparation.
Structure breakdown
The paper opens with a descriptive introduction establishing the public health significance of Alzheimer's disease and its disproportionate impact on women. It then presents five fully annotated peer-reviewed sources with critical commentary, followed by a curated list of additional relevant articles. A formal reference list closes the paper. The structure progresses logically from problem identification to source evaluation, supporting the paper's stated function as a dissertation research foundation.
Introduction: Alzheimer's Disease and Women in the United States
At present, there are more than 5 million cases of Alzheimer's disease in the United States, and this figure is projected to increase by 300% by mid-century (Vega et al., 2017). Although the Food and Drug Administration recently approved the first medicinal treatment for Alzheimer's disease, its efficacy remains unknown at present, and it is reasonable to suggest that many Americans will continue to suffer from this disorder as they grow older. While Alzheimer's disease can occur at any time during the lifespan, it is generally regarded as an age-related disorder since it typically occurs among the elderly and represents the most common cause of dementia in this population (Beckman & Morrison, 2021). Despite a small decline in life expectancy rates attributable to the ongoing COVID-19 pandemic in recent years, people are still living longer today than ever before in history. Therefore, it is also reasonable to posit that unless and until the precise causes of Alzheimer's disease are identified and efficacious treatments become widely available, the number of Alzheimer's disease sufferers will continue to increase well into the foreseeable future (Beckman & Morrison, 2021).
What is known for certain at present is that women have a higher lifetime incidence of Alzheimer's disease compared to men (Peeters et al., 2022). Researchers have also determined that Alzheimer's disease currently affects almost 50 million people globally, and that fully two-thirds of the cases in the United States are women (Beckman & Morrison, 2021). Moreover, the female population in the United States is becoming far more diverse, and the prevalence of Alzheimer's disease among African American and Hispanic women is also higher compared to men, with the largest differences existing among the same ethnicity (Royse et al., 2021). In addition, African American women are less likely to seek medical assistance when the symptoms of Alzheimer's first occur, thereby exacerbating the condition and accelerating its devastating effects on the human mind and body (Lincoln et al., 2021). Taken together, these issues make the study of the prevalence and effects of Alzheimer's disease among American women a timely and important topic that warrants further investigation.
Annotated Bibliography: Key Peer-Reviewed Studies
Andrew, M. K. & Tierney, M. C. (2018). The puzzle of sex, gender and Alzheimer's disease: Why are women more often affected than men? Women's Health, 14, 1–8.
This study cites the significant differences in the incidence and prevalence of Alzheimer's disease between men and women as a problem that warrants additional investigation. The purpose of the study was to provide a comprehensive, critical analysis of these issues using a narrative review to identify gender- and sex-based influences in the onset of Alzheimer's disease. In this regard, the authors note that there are multiple sex differences between men and women with respect to hormones, pregnancy, and brain structure that may have an influence on the onset of Alzheimer's disease. The findings that emerged from this study included the effects of longevity — because women tend to outlive men — as well as other biological differences such as hormonal and physical characteristics that may play a role. In addition, gendered social roles and educational and employment opportunities may also be implicated in the onset of Alzheimer's disease. Based on these findings, the authors suggest that additional research is needed concerning the manner in which sex- and gender-based differences combine to place women at greater risk of developing Alzheimer's compared to men. Likewise, the authors call for further studies to determine how sex and gender should be taken into account for the optimal management of this disorder. A minor weakness in this study was the minimal discussion concerning the relationship between female frailty and the onset of Alzheimer's, although this factor was included in the analysis.

This article emphasizes the fact that the world's population is living longer, with a concomitant increase in the prevalence of various types of dementia, most especially Alzheimer's disease. In response to this problem, the purpose of this study was to analyze a population of 846 women (aged 65–89 years) suffering from different stages of dementia, including Alzheimer's, using the Mini-Mental State Examination, the Dementia Behavior Disturbance Scale, and the Mini Nutritional Assessment Short-Form. The findings that emerged from this study included the fact that nutritional problems, including weight loss, are common among women with Alzheimer's disease. These problems are associated with suboptimal clinical outcomes such as high rates of institutionalization, rapid cognitive decline, and increased mortality. An especially noteworthy finding was that these outcomes can occur even among women suffering from the early stages of the disorder. Based on these findings, the authors recommend additional research to identify efficacious preventative and management strategies for women experiencing the early stages of Alzheimer's disease. Although not a weakness per se, this study used Japanese women only, meaning that there may be unidentified cultural issues involved that could also play a role in the onset of Alzheimer's disease, and that the findings may not be generalizable to other populations.
