Are seizures common with cysticercosis of the nervous system?

Yes: One of the most common causes of seizures in migrant workers, when the larva enter the brain, but is not dead--to understand it you have to see the life cycle of cysticercosis.

Yes: Those of us in southern us see lots of cistercercosis. The tapeworm gets into muscle and the develops cysts in the brain. When the cysts break down, they cause a severe inflammation that causes seizures. The cysts are dying, but create epilepsy as they do. They may calcify and leave scars. Some resolve and seizures also resolve.
