Scientists in Sarasota are concerned red tide may have long term effects on the human brain – Tampa, Florida

Sarasota, Florida — Not to be missed as the red tide approaches the coast, or even Tampa Bay. It’s that infamous smell of dead fish, and if it’s bad, it can irritate your airways. But doctors don’t think it will stop there. Now they are looking at the side effects that red tide may have on the human brain.

“When the last red tide was bad, I experienced a hacking cough like this, but I had never actually experienced it before and it disappeared. And this year, this cough is back again. I think that’s the cause, because I live near the beach and are exposed to the red tide.“” James Powell, who lives in Sarasota, said.

Powell reports such a symptom Roskamp Insitute In Sarasota, as a participant in a recent study on the effects of red tide on the human nervous system.

Daniel Niedospial, Research Assistant at the Roskamp Institute, testing samples from participants.

This study, in its second year, compares people with high or no exposure to red tide. They report intra-flowering and non-flowering symptoms and blood and urine samples.

“”The toxins released by red tide are neurotoxins that damage the nervous system. We know it’s a way to kill wildlife, a way to kill fish, manatees and dolphins, and it can affect us, “said Dr. Michael Mullen, Executive Director of the Roskamp Institute. Told ABC Action News.

With the outbreak of red tide in early 2000, scientists conducted a 10-year study of respiratory effects, especially asthma, but began recording other symptoms.

“”General fatigue, feeling sick, and a little lethargic, “explained Barb Kirkpatrick, Executive Secretary. Gulf of Mexico Coastal Ocean Observation System (GCOOS).

That was when they examined emergency room visits from 2005 to 2009 and found a significant increase in neurological symptoms of coastal zip codes.

“”There was a rise in things like headaches, especially during the red tide, “Kirk Patrick said.

“There are certain people who complain of memory and other psychic impairments during flowering,” Mullen adds.

The Roskamp Lab currently targets 250 people and compares blood levels of brevetoxin with body responses.

“For example, you can see antibodies against toxins in the blood of a particular individual long after the toxins are gone,” Maren explained. “And one of the very interesting things we’ve already seen is that there are significant differences between individuals in the levels of antibodies to toxins, even if they haven’t been exposed for as long as six months.”

One question they want to answer is: Are high levels of antibodies good or bad?

“”I don’t know how it relates to neurological complaints. If there are high levels of the antibody because the antibody is sucking up the toxin, does it reduce neurological compliance, or does it work the other way around, causing the antibody to cause problems in some way? I don’t know at this point, “says Mullen. ..

The Roskamp Institute has also conducted extraordinary research on Alzheimer’s disease. In the long run, Maren said he really wanted to know if red tide had any effect on diseases like Alzheimer’s or Parkinson’s.

“”I don’t know if this kind of toxin will make things worse. Hopefully the answer is no, but no one has ever seen this, “he explains. “We need to make sure that there are no significant public health risks here.”

Mullen and his colleagues say the answers to this study could be more important than ever, as so many people are moving to Florida, especially the coast.

The Roskamp Institute aims to add about 150 more participants. They especially need people who live inland. Click here if you want to participate..

They hope to get the first set of results by 2022.

GCOOS is also seeking research funding to investigate the effects of red tide on the skin.

Kirkpatrick said there were reports of skin rashes from people swimming in water with high levels of red tide, but they do not have a dataset showing how widespread or severe the exposure is.

“”There are case reports of skin rashes, swelling of the eyes and lips, and nasal mucosa, but what we don’t have good science for is that 1 in 100,000 people develop skin rashes after swimming in red tide. is. 1 in 100? She explained.

GCOOS also created Beach forecast website To see before people go out on the beach day. Updated every 3 hours, you will be notified if there is a better time when the red tide is low and may flow into the shore.
