A1: Overview of Public Health Issue
Parkinson's disease is among the most significant neurodegenerative public health
problems in America, involving the degeneration of dopaminergic cells, leading to serious motor
and non-motor complications. With an aging population, this condition is imposing tremendous
pressure on community healthcare facilities and family caregivers coping with the advanced
symptoms associated with Parkinson's disease (Yang et al., 2025). The public health significance
of PD is more than just its morbidity because PD is a powerful cause for death among the older
population of the USA, requiring effective epidemiological monitoring and state-level
interventions (National Centre for Health Statistics, 2025). First, the death rate from Parkinson's
disease among adult US residents aged 65 years and above is at an all-time high of 72.0 deaths
per 100,000 standard population (National Centre for Health Statistics, 2025). Secondly, the
long-term surveillance carried out from 2018 to 2024 indicates that there is a steady and
statistically significant increase in crude and age-adjusted death rates from neurodegenerative
disorders in domestic vital statistics databases (CDC, 2025). Thirdly, there is a considerable
demographic discrepancy, whereby men experience twice the mortality rate of women, which is
evident in all elderly populations (National Centre for Health Statistics, 2025). Lastly, the
evidence both globally and country levels shows that the increasing burden of the disease is not
consistent, as the age-adjusted prevalence and disability adjusted life years associated with the
disease have risen by more than 20% during the last couple of decades (Yang et al., 2025).
A1a: Importance of Studying the Issue
The epidemiological assessment of Parkinson's disease mortality and morbidity is the
vital empirical base necessary for mapping the disease, predicting health care resource usage,
and instituting effective public health measures. Given the long-time span over which
Parkinson's disease unfolds, an epidemiological approach to its metrics facilitates identifying the
particular environmental, occupational, and lifestyle risk factors responsible for geographical and
demographical differences (Ben-Shlomo et al., 2024). For instance, spatial data collected from
vital statistics reveal significant disparities in mortality levels across different regions, with some
states having exceedingly high age-adjusted mortality rates relative to the rest of the country
(CDC, 2025). Therefore, this study would facilitate the development of early detection screening
programs, provision of specialized neurological care in affected areas, and formulation of
, 3
policies aimed at reducing the exposure to environmental stimuli like industrial solvents and
pesticides (Ben-Shlomo et al., 2024).
Quantitative monitoring also provides information for healthcare resource allocation and
policy-making for this growing group of vulnerable elderly. The national survey trends show that
the rise in rates of chronic diseases aligns with the greater demand for health insurance and
changes in patterns of healthcare utilization, including visits to urgent care centers and retail
health clinics (Norris et al., 2026). As the actual numbers increase to reach the high-risk
population, an inevitable increase in motor decline, cognitive impairment, and other
complications including death from aspiration pneumonia is expected to exceed the capacity of
current long-term care institutions (Yang et al., 2025).
A1b: Target Audience and Significance
The primary target population for the epidemiology report entails the state public health
officers, healthcare policymakers, and state department of health directors. This choice is
justified since such entities have the legislative mandate, financial powers, and appropriate
organizational framework to allocate health care resources, establish registries, and intervene to
address the issue. The report is important to these bodies as it will help convert complicated
mortality figures like the rising age-adjusted mortality rate of 72.0 per 100,000 in elderly people
and two-fold sex disparities involving men into concrete health planning information (National
Centre for Health Statistics, 2025). The results of this study will enable the target audience to
make a shift from responding clinically to being able to proactively manage the escalating
economic and clinical burden of Parkinson’s disease in their communities.
A2a: Exploration of Epidemiological Data Sources
Utilizing multiple disparate data sources is very important when conducting an
epidemiological study of the disease. If one were to use only one source, there would be a
problem with systematic bias, because it would narrow the viewpoint of the disease to just one
aspect of it, such as initial manifestation or final mortality registration. On the other hand, the
use of information from different databases of vital statistics, national surveys, cohort studies,
and meta-descriptions of global prevalence provides a way for scientists to triangulate evidence
and validate trends (Ben-Shlomo et al., 2024). Such an approach combines a wide perspective of
global health metrics with a narrowed perspective of local population-specific databases, thus
