Overview: pathophysiology and management of cerebral malaria.
Cerebral malaria is still a major cause of death in patients suffering from malaria. Much of the research work in the past two decades has been done to clarify the pathophysiology of cerebral malaria which hopes to improve the management of the disease and concomitantly reduce mortality. However, the pathogenesis of cerebral malaria is still not clear. The pathophysiology of coma is believed to be brain anoxia from ischemia due to sequestration of erythrocytes containing mature parasites in cerebral capillaries and venules. Three possible mechanisms of sequestration (cytoadherence, rosette formation and decreased deformability of the infected erythrocytes) are postulated. The management of cerebral malaria includes early diagnosis and early treatment with potent antimalarial drugs, early detection and treatment of complications, correction of fluid and electrolyte imbalance and proper nursing care. In spite of these efforts, a high mortality rate (ranging 10-40%) is still encountered.
