Neurocysticercosis

Abstract

Neurocysticercosis is the most common parasitic disease of the central nervous system. Varied clinical manifestations occur, due to deposition of larvae of the parasite Taenia solium in cerebral parenchyma, meninges, spinal cord, muscles, eyes and skin. The diagnosis of neurocysticercosis can be made with a fairly high degree of accuracy with the help of computed tomography and magnetic resonance imaging. Serological tests and histopathological examination of subcutaneous nodules provide additional support in establishing the diagnosis. The anticysticercal drugs albendazole and praziquantel have been extensively used, and found to be effective for all types of neurocysticercosis. However, recently controversy has been raised about their safety, and long-term clinical usefulness. Preventive health measures, such as provision of safe drinking water and excretion disposal, still offer the best ways to manage this disease.
