Understanding the Silent Epidemic: Movement Disorders in Cabo Verde
The global conversation around non-communicable diseases (NCDs) often focuses on heart disease, diabetes, and cancer. But a new study published in the International Journal of Public Health highlights a critical, and often overlooked, area of concern: movement disorders. Led by Leida Tolentino, Psychology Department Chair at Santa Barbara City College, the research team’s work provides the first comprehensive epidemiological data on these conditions in Cabo Verde, an island nation off the coast of West Africa. While headlines might suggest a simple prevalence rate, the study reveals a complex interplay of demographic vulnerability, access barriers, and a pressing need for integrated public health strategies—a story deeply rooted in personal loss and a commitment to societal benefit.
The study’s findings indicate an age-standardized prevalence of 17 per 100,000 population for movement disorders, with Parkinson’s disease accounting for a significant 79% of these cases. This figure, while seemingly modest, is particularly concerning given Cabo Verde’s aging population and the projected increase in NCDs globally. What’s often missed in reporting these numbers is the profound impact these disorders have on individuals and their families. Over half of the participants in the study (51%) reported a strong or extreme impact on their quality of life, stemming from both physical limitations and emotional distress like sadness, lack of motivation, and anxiety. This underscores the need to move beyond simply quantifying prevalence and to understand the lived experience of those affected.
A Father’s Legacy and the Birth of a Foundation
The impetus for this research wasn’t purely academic; it was born from a deeply personal tragedy. Tolentino’s father, André Corsino Tolentino, was diagnosed with progressive supranuclear palsy (PSP), a rare and debilitating neurodegenerative movement disorder. Before his passing, he documented his journey in a diary-style book, Victory is Today: My Relationship with Progressive Supranuclear Palsy (PSP), and expressed a desire to inspire a project focused on literacy, advocacy, and research related to movement disorders in Cabo Verde. This wish spurred the creation of the Fundação Doenças do Movimento em Cabo Verde, a foundation dedicated to advancing understanding and support for individuals living with these conditions. The study itself, therefore, represents a tangible manifestation of a father’s hope and a daughter’s dedication.

Identifying Vulnerable Populations and Access Barriers
The research wasn’t just about establishing prevalence; it aimed to identify at-risk groups and pinpoint obstacles to care. The study revealed a concerning trend: men and individuals aged 60 and older are disproportionately affected. Furthermore, a significant 23% of patients diagnosed before the age of 50 reported exposure to potentially harmful materials like iron, copper, or pesticides—substances increasingly linked to a heightened risk of Parkinson’s disease. This finding raises important questions about environmental factors and occupational hazards within Cabo Verde and suggests a need for further investigation into potential causal links. Perhaps most striking, however, is the widespread difficulty in accessing medication, with 70% of participants reporting moderate or severe challenges. This highlights a critical gap in the healthcare system and underscores the need for decentralized services and strengthened public health infrastructure.

While the study focuses on Cabo Verde, its implications extend far beyond the island nation. The challenges identified—aging populations, environmental exposures, and limited access to care—are increasingly common in low- and middle-income countries. Dr. Filipe Monteiro, a mathematician and co-author from Brown University, played a crucial role in the study’s design, emphasizing its potential to inform public health policy in other regions facing similar circumstances. The methodology employed—a combination of data collection at local health institutions, online surveys, and personal interviews—provides a robust framework for future epidemiological studies in resource-constrained settings. This approach is particularly relevant for regions where comprehensive data on neurological disorders is lacking, allowing for targeted interventions and resource allocation.
Limitations to Consider
It’s crucial to acknowledge the limitations of this study. The data collection period, spanning July to December 2024, represents a snapshot in time and may not fully capture the long-term trends in movement disorder prevalence and incidence. The reliance on self-reported data, while providing valuable insights into patient experiences, is susceptible to recall bias. Furthermore, the study’s focus on Cabo Verde, while providing a detailed understanding of the local context, may limit the generalizability of its findings to other populations. While the researchers obtained approval from regulatory authorities in 2022, the complexities of conducting research in a geographically dispersed island nation undoubtedly presented logistical challenges.
The Path Forward: Integrating Neurology into Public Health
The publication of this study marks a significant milestone in understanding movement disorders in Cabo Verde, but it’s just the beginning. Tolentino and her team are already planning follow-up research to investigate the environmental factors contributing to early-onset Parkinson’s disease and to evaluate the effectiveness of interventions aimed at improving access to care. A key next step will be to integrate neurological assessments and care into existing NCD and aging policies, ensuring that individuals with movement disorders receive timely diagnosis and appropriate treatment. The question now is whether Cabo Verde’s government and healthcare providers will heed the study’s call to action and prioritize the needs of this vulnerable population—and whether other nations facing similar demographic and epidemiological challenges will learn from Cabo Verde’s experience.
