Heatstroke is a syndrome consisting of life-threatening central nervous system and multiple organ dysfunction from complications of hyperthermia. Additionally, there is an associated complex immunological and inflammatory component to the illness that resembles sepsis. Core body temperature exceeds 40 degrees C with associated mental status changes such as delirium and coma. ⋯ Classic heatstroke is nonexertional, environmentally related and exertional heatstroke occurs in the setting of strenuous exercise. Heatstroke is actually the most severe of a continuum of heat-related illnesses that carries a high incidence of mortality. Treatment is directed at rapidly reducing core body temperature and the management of life-threatening systemic complications.

Neurocysticercosis is the most common helminthic disease of the nervous system and currently represents a major public health problem in developing countries of Latin America, Asia, and Africa, as well as in industrialized nations with a high immigration rate of people from endemic areas. The disease occurs when humans become the intermediate host in the life cycle of Taenia solium by ingesting its eggs from contaminated food. Neurocysticercosis is pleomorphic in its presentation due to individual differences in the number, size, and location of the parasites, as well as differences in the severity of the host's immune reaction to the parasite. ⋯ The diagnosis of neurocysticercosis is based on clinical data, neuroimaging abnormalities, and the results of immunological tests. Two drugs, albendazole and praziquantel, are cysticidal and destroy most intracranial parasites; however, surgery may be necessary in the management of some forms of the disease, particularly hydrocephalus and intraventricular cysts. Although the development of modern diagnostic tests and the introduction of potent cestocidal drugs have increased our ability to make the diagnosis of neurocysticercosis and improved prognosis, some patients still have a torpid clinical course despite prompt diagnosis and proper therapy.
