What this trial studies

This observational study aims to explore the biological impacts of environmental toxins, particularly those released during harmful algal blooms, such as brevetoxins and microcystin. It will assess the association between exposure to these marine toxins and the prevalence of neurological disorders, respiratory issues, and other health symptoms. Participants will be monitored through multiple visits to evaluate their health in relation to toxin exposure from local waters. The study seeks to understand the long-term effects of these toxins on cognitive and immune health.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 or older who reside in southwest Florida counties affected by harmful algal blooms.

Not a fit: Patients with medical conditions that make enrollment inappropriate or those unable to provide biological samples may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the health risks associated with harmful algal blooms, potentially leading to better public health guidelines and interventions.

How similar studies have performed: While studies on environmental toxins exist, this specific investigation into the neurological impacts of harmful algal blooms is relatively novel.
