What are the complications of cysticercosis?

The potential complications of cysticercosis may include the following:

  • Seizure
  • Stroke
  • Vision changes
  • Cognitive problems
  • Death

In general, the prognosis for the majority of patients with cysticercosis is excellent with proper management. Patients with NCC and seizures have a good prognosis if the patient obtains the proper treatment regimen and if the acute lesions clear on subsequent imaging exams of the brain.

How is cysticercosis prevented?

The prevention of cysticercosis can be achieved through various measures including the following:

  • Public education regarding the parasite and its route of transmission
  • Avoidance of raw or undercooked pork in endemic areas
  • Avoidance of potential fecal-oral routes of transmission through routine hand washing, good personal hygiene, as well as through the proper handling and preparation of foods
  • Meat inspection and the proper disposal of infected meat in endemic areas
  • Improved sanitary measures for human waste disposal in endemic areas
  • Screening contacts of infected individuals and instituting appropriate treatment
  • Developing a vaccine for the prevention of cysticercosis which may be used in the future; currently, there is no vaccine approved for use in humans, though there have been advances in vaccines being used in pigs
