neurological symptoms

The Duval County Health Department recently confirmed its first case of measles in an unvaccinated child.

One spring morning in 2015, Barbara Lipska got up as usual, dyed her hair and went for a jog in her suburban Virginia neighborhood.

But when she returned from a much longer than expected run, her husband Mirek was completely taken aback.

"I was lost in my own neighborhood," Lipska says. "The hair dye that I put in my hair that morning dripped down my neck. I looked like a monster when I came back home."

It's the most common marine toxin in the world, but many aren't familiar with the all-too-common ciguatoxin. Even less well known are the severe—and often bizarre—neurological symptoms that accompany exposure.
