Study finds some may experience neurological effects from breathing in red tide toxins

SARASOTA COUNTY (WFLA) – More than 250 residents of five coastal counties, including Sarasota and Manatee counties, participated in a study of the impact of red tide on the human brain. The findings, published last week, suggest some people may experience neurological effects from airborne red tide toxins.

“In previous studies by Dr Barbara Kirkpatrick and her team, a number of people reported headaches, so I thought it would be a good idea to take a look at what’s going on. ‘other in relation to the brain,’ said Roskamp Institute lead scientist Dr. Laila Abdullah. “So for that reason, we did the brain health effects study in individuals who were either blooming or not blooming so that we could compare if there was an increase in symptom reporting. neurological.”

The study found that a number of people reported neurological symptoms typically reported by people who ingest seafood contaminated with red tide toxins. Symptoms included headache, dizziness, numbness, nausea, tingling and reversal of hot/cold sensations.

However, study participants had not eaten contaminated seafood. They had only been exposed to airborne red tide toxins.

“People who tended to have a history of migraines and chronic fatigue syndrome tended to report more of these symptoms than other people,” Dr. Abdullah said.

Many questions remain unanswered, such as the level of dose needed to trigger symptoms. Scientists say more research is needed.

“We don’t know how long it lasts. Some of the effects disappear, such as respiratory effects and headaches, but we don’t know the other symptoms and we need to do more studies to understand them better,” Dr Abdullah said. “I think with climate change and more people moving to the area and more of us being exposed to red tide blooms, we really need to understand the health effects of red tide blooms. red tides in our area.”
