Neurocysticercosis - What Is It & How Can It Affect You
 Neurocysticercosis is an infection in the brain caused by the larval form of the pork tapeworm. These parasites can be found in humans and pigs in Asia, Africa, South America, parts of Southern Europe, and areas of the United States where they infect people who eat raw or undercooked pork. When pork tapeworms enter the body, they begin to form cysts and cause an infection called cysticercosis. Neurocysticercosis is the form of cysticercosis found in the central nervous system.
Infections occur when a person accidentally swallows tapeworm eggs. These eggs are passed via bowel movement, and the tapeworms are spread through unsanitary water, contaminated food or soil, or any other surfaces tainted with the infested feces. Once the eggs are ingested, they will hatch and the tapeworms will penetrate the intestine, travel through the bloodstream, and develop into lesions in the muscles, brain (neurocysticercosis), or eyes.
When you have neurocysticercosis, you may experience:
- Seizures
- Headaches
- Lack of concentration
- Difficulty keeping your balance
- Swelling of the brain
Death is even possible if you are severely infected with pork tapeworms. It may take a few months to years for any symptoms of neurocysticercosis to appear. Suffers usually begin to experience symptoms when the giant cysts in their brain begin to die, causing the brain to swell and create pressure.
If you suspect you may have neurocysticercosis, consult your physician. MRI and CT brain scans are testing methods your physician may use. Your doctor may also ask you about your travels, as well as your eating habits, when diagnosing you. Prescription drugs are a common treatment for neurocysticercosis, although some patients may need a shunt to alleviate some of the pressure caused by the swelling in their brain.
