Effects of red tide neurotoxins on the nervous system

Neurological effects of aerosolized red tide neurotoxins

['FUNDING_R01'] · ROSKAMP INSTITUTE, INC. · NIH-10981270

This study is looking at how toxins from harmful algae in the air might affect the brains of people living in southwest Florida, especially those who often get migraines or feel very tired, and it will also check if certain genes play a role in these effects.

What this research studies

This research investigates how aerosolized neurotoxins from harmful algal blooms, specifically Karenia brevis, affect the human central nervous system. It focuses on residents of southwest Florida who may be exposed to these toxins, particularly those with a history of migraines or chronic fatigue syndrome. The study aims to understand the neurological symptoms associated with exposure, including memory problems and fatigue, and how genetic factors like the apolipoprotein E e4 allele may influence these effects. Blood tests will be conducted to detect the presence of neurotoxins and related antibodies in participants.

Who could benefit from this research

Good fit: Ideal candidates for this research include residents of southwest Florida who have experienced symptoms related to neurotoxic shellfish poisoning or have a history of migraines or chronic fatigue syndrome.

Not a fit: Patients who do not reside in areas affected by harmful algal blooms or who have no history of neurological symptoms related to red tide exposure may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to better understanding and management of neurological symptoms caused by red tide exposure, improving health outcomes for affected individuals.

How similar studies have performed: While research on harmful algal blooms is ongoing, the specific investigation into aerosolized neurotoxins and their neurological effects on humans is relatively novel and has not been extensively studied.
