Beneath its quaint exterior, Rio Grande City in southern Texas harbors a concerning dilemma. The municipality, home to around 15,000 individuals, reports some of the highest dementia prevalence in the United States.
The Alarming Dementia Rates in Rio Grande City
Within this border town, approximately one in four residents aged 65 and above are affected by dementia, in contrast to the national average of about one in ten.
Dementia researchers suggest that this figure is likely an underestimation. Dr. Gladys Maestre, who heads a dedicated dementia and Alzheimer’s research initiative at the University of Texas Rio Grande Valley, warns that the actual number of cases could be substantially higher.
Underreporting: A Significant Issue
Many residents lack health insurance, leading to undiagnosed and unreported dementia cases. Furthermore, access to healthcare services in the area is challenging, obscuring the true extent of the issue.
Community Impact
Locals in Rio Grande City and the surrounding Starr County report that nearly every family has a member affected by dementia. The condition impairs memory, language, problem-solving, and other cognitive abilities.
Dr. Maestre emphasized the need for a comprehensive study to accurately assess the prevalence of dementia in the region. “The only way to provide precise estimates is by conducting an epidemiological study, going door to door if necessary,” she noted.
Factors Contributing to High Dementia Rates
The Role of Poverty
Poverty is a major contributing factor, with Starr County’s poverty rate nearing 30%, more than double the national average of around 12%. Lower incomes and disadvantaged neighborhoods can escalate dementia risk due to:
- Poor air quality
- Insufficient social interactions
- Increased stress levels
Environmental Contaminants
Dr. Maestre also points to environmental pollutants. The water supply and aging houses in Rio Grande City contain hazardous substances, including:
- Arsenic, linked to cognitive decline in youth
- Cadmium, a carcinogen associated with industrial and agricultural activities, known to contribute to dementia development
Extreme heat in South Texas further exacerbates the issue. Elevated temperatures can stress the body, negatively impacting cognitive function and increasing the risk of dementia-related deaths and hospitalizations among older adults.
Demographic Factors
Like other regions with significant minority populations the Hispanic community within Stallr County has historically been highlight increased risk of developing dementia, but the causes of this disparity are not fully understood.
Factors such as cardiovascular disease, socioeconomic status, and genetic predispositions may play a role.Mayra Garza volunteers at Dr Falcon’s El Faro Health and Therapeutics clinic emphasizes the urgent need for action, driven by personal experience with the disease.
A Call for Action
Dr. Maestre urges immediate intervention to prevent tragic events, such as the recent discovery of an 84-year-old woman with dementia, missing in Roma, Starr County.
She highlights the “perfect storm” of environmental issues and adverse life experiences, rendering the brain more susceptible to dementia. Extreme heat, pollution, and a car-dependent environment all contribute to this vulnerability.
To mitigate the situation, Dr. Maestre advocates for more research and improved infrastructure for dementia care and prevention, with $3 billionTexas research fund being entering the house of senate.
The Dementia Prevention and Research Institute of Texas, if approved, aims to fund research and foster collaboration among universities, medical institutions, and experts.
The Texas Department of State Health Services reports that 459,000 Texans are diagnosed with Alzheimer’s, accounting for about 12% of the state’s population aged 65 and above. Symptoms often include:
- Memory loss
- Irritability
- Difficulty following conversations or finding the right words
- Confusion about time and place
