California's Unspoken Health Problem: Brain Parasites
An anonymous reader writes "Sunnyvale, California is a town 40 miles outside of San Francisco, in the Bay Area. As in most of California, the weather is mild, and the winters are short, even sometimes warm. On December 20, Sara Alvarez took her youngest child for a walk in the park in town. As daylight faded, Alvarez lost feeling in her right leg, then her left foot. Her body became numb, and she became weak. At 10:15 pm, her husband drove her to a hospital in Redwood City, about 20 minutes away from their town. There, over the course of Christmas, doctors batted around diagnoses: tumor, cancer. Finally, Alvarez received a brain scan that revealed the truth: neurocysticercosis, a calcified tapeworm in her brain (link contains images of brain surgery)."
Alvarez says she experienced debilitating headaches for 20 years before her diagnosis, but she probably consumed tapeworm eggs much earlier than that. When Alvarez immigrated to the United States in the late 1980s she complained to American doctors of a pain so absolute it blinded her and made her vomit.
The parasites apparently were contracted outside of the United States according to the article contrary to all of the other comments and contrary to what the Slashdot summary seems to imply.
