Red tide air toxins and brain health

Neurological effects of aerosolized red tide neurotoxins

NIH-funded research Roskamp Institute, INC. · NIH-11175422

This project looks at whether breathing red tide toxins causes memory problems, fatigue, or other brain symptoms in coastal residents, especially people with APOE e4 or a history of migraines or chronic fatigue.

What this research studies

If you live near the Gulf Coast, researchers will collect air samples during red tide blooms and take blood tests to measure brevetoxins and antibodies while asking about neurological symptoms. They will also offer genetic testing for APOE variants and compare people who report symptoms to those who do not. The team will link air measurements, blood toxin levels, immune markers, and symptom reports to look for dose–response relationships. The work focuses on whether people with migraine, chronic fatigue, or the APOE e4 gene are more likely to experience brain-related effects from aerosolized brevetoxins.

Who could benefit from this research

Good fit: Ideal candidates are Gulf Coast residents or visitors exposed to red tide aerosols who experience memory problems, fatigue, headaches, or other neurological symptoms, and people with a history of migraine or chronic fatigue.

Not a fit: People who live far from red tide events, are not exposed to aerosolized brevetoxins, or whose symptoms have a different known cause are unlikely to benefit directly from this project.

Why it matters

Potential benefit: If successful, this work could help identify who is most at risk and inform protections or treatments to reduce brain-related effects from red tide exposure.

How similar studies have performed: Prior work has detected brevetoxins and antibodies in blood and linked exposure to short-term NSP-like symptoms, but using genetic risk (APOE e4) and detailed air-to-blood dose relationships is a more recent and relatively novel approach.
