Introduction
Overview of Dementia and Its Importance in Public Health
The cognitive disorders known collectively as dementia, in which there are progressive deficits
in reasoning, processing of new information, and other cognitive domains, are a major
international health issue. Since it is a progressive disease, dementia mainly occurs in the elderly
population, which results in a significant loss of the quality of their routine chores. Family and
caregivers are also affected by the disease in their loved ones, while the healthcare sector
experiences a burden in handling such patients. Lois Beckett explains, 'Experts believe that the
global rise in dementia can be attributed to the longer life people are living and the growing
aging population of the world.' Estimations have predicted that the global population of dementia
is expected to rise by three-fold in the year 2050, with around seventy percent of those affected
being in LMICs (Mattap et al., 2022, p. 7407). Implicity: This demographic change enforces a
need for dementia as a public health priority. As a global health issue, governments and health-
related agencies must be involved in the formulation of policies and comprehensive approaches
on how to keep the impacts of dementia under control.
The inability to spread from one person to another is attributed to the fact that dementia as a
disease is non-communicable. Nevertheless, the modifiable risk factors involving cardiovascular
disease, diabetes, and lifestyle factors linked to dementia are within the capability of public
health initiatives (Parial et al., 2021, pp. 1398). Thus, knowledge of the epidemiology of
dementia marks a vital step on the path to the prevention and proper treatment of the issue.
Epidemiological research is important to supply descriptive data on incidence as well as
prevalence, risk and protective factors, and the prognosis and outcomes of dementia in order to
improve public health strategies.
The Selected Study and Its Importance
A deliverable focus has been set on the study titled "Dementia Incidence, Burden, and Cost of
Care: This paper aims to review a local Filipino community study of facial recognition
technology, which was published in 2021. This research, conducted by Dominguez et al. (2021,
p. 628700), offers important information on the prevalence, morbidity, and cost attributable to
dementia in the Philippines. This study demonstrates the significance of relevant epidemiological
data based in LMICs because of the scarcity of resources and other health issues, which may
outweigh the importance of mental health across these nations. The significance of the selected
study relates to the fact that it presents the initial data on dementia, including in the Filipino
community. This information is useful in the creation of a national dementia plan, thereby
stressing the importance of government involvement in public health planning as well as the
management of resources (Dominguez et al., 2021, p. 628569). The study presents robust
evidence on dementia incidence and cost and provides a strong argument for dementia care and
prevention foregrounding in national health policies to reduce the burden of dementia on the
population.
The implications of the study that has been undertaken point to the prospects for other LMICs
that are experiencing similar challenges. Thereby, the findings of the current study might be
useful for planning interventions on an international level and help in creating the guidelines
needed for the effective management of dementia. Due to the growing dementia rate worldwide,
interprofessional partnerships are crucial to improving the solution to this significant health
challenge.
Discussion
Critical Evaluation of Findings
Dominguez et al. (2021, p. 628500) observed a crude incidence of dementia of 16 per 1,000
person-years, and the estimated risk was higher in women than in men. The work shows that
Alzheimer's disease is expected to claim millions of lives within the next few decades, both in
developed and developing countries, and impose vast costs on global public health and the
economy.
Findings Interpretation
The results given in the work describe a patient's gender differentiation of dementia and agree
with the international data indicating more frequent dementia in females at certain ages. This is
important for the demonstration of the factors that correlate with dementia regarding
demographic structure and for the development of the proper niche interventions. Due to the
projections that indicate increased development of dementia in the future, public health measures
have to be implemented for future prevention costs. This paper concludes that as the elderly
population increases, so does the prevalence of the condition dementia, which will exert further
pressure on the already underpressure health services as well as the affected caregivers.
The observations made in the study concerning the gender differences could somehow be
explained by differences in age, life behaviors, and remaining lifespan, as well as genetic
predispositions. Also, it has been proven that females live longer than males, which means they
have higher chances of getting affected by dementia. These are hormonal changes and genetic
factors that may contribute to dementia prevalence in women, as is evidenced by research from
the study by Udeh-Momoh and Watermeyer (2021, p. 101927). It is thus significant to have a
clear understanding of these factors so as to improve on the risks that affect each gender in
relation to dementia.
Evidence Level
This study is also considered to have a high level of evidence, mainly because the authors used a
prospective cohort design, which is effective in describing rates of incidence and prevalence.
One of the strengths of the study design is the ability to examine dementia burden and rate of
progression within the same population of subjects, which provides a naturalistic perspective on
the disease course (Jørgensen et al., 2020, p. 912). However, certain limitations in the study
include the missing neuroimaging data and a significant percentage dropout rate that might
reduce the validity of the findings. These are important considerations when drawing
implications from the research findings and designing subsequent studies.
Indeed, longitudinal studies are very useful in epidemiology since they provide temporal
associations between factors that cause diseases and the diseases themselves. As is the case with
dementia, such studies assist in defining factors that may precipitate the disease and markers for
its intensity, which is useful in framing preventive measures. The larger the size of a group, the
more likely it is to be representative of a larger population, which makes the results valid for
other individuals as well.
Strengths and limitations
Strengths: High research reliability and a low possibility of rater bias result from the
combination of doorknob assessments and the application of structured diagnostic criteria. Its
target group, based on a cohort, is well suited to follow dementia and its effects in a community.
The selection of patients in the real-life clinical setting specified in a well-defined cohort and
applying consistent diagnostic procedures increases the external validity of the conclusions
drawn (Carrero et al., 2023, p. 55). In addition, the follow-up of the study is three years from the
assignment of a bad credit score, which is relatively short for drawing definite conclusions. Nine
years of tracking is also close to other longitudinal research, meaning that the data presented here
can be compared with other similar works.
Limitations: Some of the compounding weaknesses include high standards of attrition and the
unavailability of neuroimaging results to support the diagnoses. There is a concern about the
generalizability of the data and results because the study is situated only in Marikina City.
However, it is the most representative City in the study region. Such factors could potentially
add bias, which may reduce the extent and scope to which the findings could be generalized
(World Health Organization, 2021). Settings for future research should include neuroimaging
and samples that cover a larger geographical region. Another weakness of the study is that some
of the variables, particularly lifestyle factors and medical history, were taken as self-reported,
making it more likely to be impacted by reporting biases.
Implications for Public Health Practitioners
The evidence presented in the study has several critical implications for public health:
Policy Development
The findings can be used to create a comprehensive national dementia care plan for the
Philippines that calls for early diagnosis initiatives against modifiable risk factors and support for
caregivers. This information can be used by policymakers to appropriately apportion funding, in
addition to finding ways to combat the increasing prevalence of dementia. Creditor states must
establish comprehensive policies to incorporate dementia care into general public health policies
due to this emerging health concern. According to DMS-D AA, a national dementia plan should
involve such areas as raising awareness among the population, staff education and training, and
the development of specialist services such as care homes for people with dementia (Pit et al.,
2024, p. 23). Suppose the government accepts dementia care by prioritizing it. In that case, it can
ensure that dementia patients have the right support and treatment delivered to them in the
indicated time, thus enhancing their quality of life and alleviating the burden on the caretakers.
Resource Allocation
Upon reviewing this material, it was evident that the authors established an economic impact of
dementia in terms of costs incurred in providing medical attention and support, which should
encourage healthcare policymakers to provide subsidized medical care to dementia patients. Due
to the scarcity of resources coupled with high costs, resource allocation in an efficient manner
could go a long way in alleviating the pressure on most families as well as ensuring the best
quality of care for the affected individuals. More support means investing in dementia care first,
and then the welfare of the patients as well as their caregivers would be well taken care of by the
government. The study shows more indirect costs since most of the caregiving responsibilities
are offered without charge and are borne by the families. Despite the patients' improved quality
of life, Strommen et al. (2020, p. 353) suggest that policymakers should look at the avenue of
supporting and subsidizing financially such core family caregivers and respite caregiving
services as well. Also, funding teletherapy or other community-based programs that may assist
caregivers in their responsibilities and ensure they are addressing their own needs while helping
the patients will also increase their resilience.
Public health programs
It is possible to use the findings for the development of specific public health interventions to
reduce the incidence of dementia, including raising awareness of the reversible causes and
improving cognitive health and well-being among older individuals. These programs can make
people realize the need to take proper care of their brains as well as avoid activities that are likely
to trigger dementia. Offering such non-pharmacological measures as intervening with
communities and campaigning may help people change lifestyle-related behaviours and prevent
the development of dementia (Thijssen et al., 2022). Physical activity, an adequate diet, and
mental activity must be used as the basis of interventions that help public health programs
prevent cognitive decline. Further, interventions aimed at lowering cardiovascular risk factors,
including hypertension and type 2 diabetes, contribute to the prevention of dementia. To enhance
the implementation of these programs, there is a need for organizational, community, and
political support for their implementation.
Implications
Recommendations for Improvement
To enhance the validity and applicability of future studies, several recommendations are
proposed:
Enhanced Methodology
Using neuroimaging techniques and biomarkers would enhance diagnostic certainty as it would
yield more specificity for dementia subtypes and their progression. Neuroimaging might be able
to assist in determining the aetiology of the diverse dementia syndromes and distinguishing
between the pathologies. Further, biomarkers can act as early diagnostic tools that can signal the
early stages of disease in order to enable responsive measures to be taken. The use of better
diagnostic techniques also contributes to the improvement of dementia insights as it increases the
level of accuracy. Magnetic resonance imaging and positron emission tomography are able to
identify and differentiate structural and functional changes in the brain in relation to dementia.
These amendments can also be useful in the detection of amyloid plaques and neurofibrillary
tangles that are characteristic of Alzheimer's disease. Thus, the combination of neuroinformatics
with epidemiology provides a basis for identifying the neural networks of the disease and
increasing the effectiveness of diagnostics.
The Lens of a Broader Geographic Scope
Researching different areas across the Philippines would also provide a broader result, which
would minimize the regional factors that may exist contributing to dementia risk factors in the
country. The comparison of the rates between the urban and rural regions can help to get a
general view of how the conditions within these areas contribute to the development of dementia.
Available local research can reveal existing areas of concern that people within a given region
are going through so that the government can devise sensitive approaches to addressing issues
related to public health. That is why geographic diversity in research can be used to reveal
differences in the rate of dementia and potential risk factors. These elements could include, but
are not limited to, SES, healthcare facility access, and cultural factors, to name but a few. Cross-
sectional research differs from within-country studies in the sense that researchers are able to
compare and look for differences and, from there, further the search for solutions for the
different groups that need intervention.
Longitudinal Follow-Up
It would be possible to collect more profound data regarding the participants' outcomes in the
long term by lengthening the follow-up period and encouraging or supporting the participants'
retention after the experiments' completion. From a research perspective, longer follow-up
periods can also provide further insight into how patients with dementia progress over time and
the various modifying factors that may be observed. It is also argued that participants who
experienced weekly follow-ups and incentive-based encouragement committed more to their
participation and thus had more consistent data (Catherine et al., 2020, p. 8). Some study
participants may need further follow-up and contact to elicit the required information or details.
Cohort studies also enable researchers to look at the effects of time, including changes in
cognition, the progression of the disease, and the effects of interventions. Participants can also be
contacted routinely through phone calls, home visits, or social media. It helps increase the
response rate of participants and also reduces the number of errors resulting from recall.
Written Communication of Science to the Public
Dementia Study Highlights
Title: A Filipino Community-Based Study on the Prevalence and Impact of Dementia, Including
Incidence and Caregiving Expenses
Conducted by: St. Luke's Medical Center researchers, Dominguez et al. (2021, p. 628601) from
the Institute for Dementia Care Asia and other institutions.
Study Period: 2011–2016
Location: Marikina City, Philippines
Focus: This research aimed at exploring the prevalence, cost, and economic impact of dementia
among the elderly population in Marikina City.
Primary Findings:
· Incidence Rate: In this regard, the research observed that the dementia rate of the population in
the study was 16/1,000 person-years, with women bearing a higher risk than their male
counterparts in the sample population.
· Future Projections: According to the study, the higher the number of new dementia cases in
the Philippines, the higher the prospects of 220 632 new dementia cases in the country by the
year 2030.
· Economic Burden: The total expenditure on care in a year was expected to be around $4,070
per dementia patient if the extent was 36. Taking it as seven percent of the average family's
annual income, such costs were mostly implicit, reflecting expenses that the family bore due to
unpaid caregiving.
Significance:
· Public Health Impact: These results underscore the necessity for a national dementia plan in
the Philippines, especially given the increasing number of seniors. Special emphasis in this plan
should be placed on simple degrees of dementia, risk factors, and some important care support
for families that have dementia patients.
· Policy Recommendations: Based on the findings, it is crucial for the government to take
further actions regarding the reduction of the imposed cost on the family and to ensure that
dementia patients have access to proper healthcare. To this effect, the purpose of this study is to
enhance understanding of the levels of the disease and compel policymakers.
Conclusion
This paper aims at critically assessing the chosen epidemiological study on dementia and
discussing how it is useful to the Filipino population. The study can contribute to the formation
of the significant data necessary for forming national policies and programs in the sphere of
public health that are targeted at overcoming the problem of dementia. Consequently, with the
help of the identified improvements and using the results of the study, practitioners in the field of
public health can be more prepared for the further problems that dementia is going to present.
Concerning the findings that this study identifies with dementia incidence, burden, and economic
issues, it highlights the tough times affected people and their families have to go through.
