Cerebral Malaria•severe complication of falciparum malaria
• mortality of 30-50%•associated with sequestration in micro-vasculature of brain
•a diffuse encephalopathy with loss of consciousness• consciousness ranges from stupor to coma• unresponsive to pain, visual, and verbal stimuli• convulsions frequently observed• onset can be gradual or sudden
Complications Associated with Falciparum Malaria
• cerebral malaria• anemia• hyperpyrexia• hypoglycemia • acidosis• GI and liver syndromes• pulmonary edema• blackwater fever• algid malaria (shock)
Features Indicating Poor Prognosis in Severe Malaria• impaired consciousness• repeated convulsions• respiratory distress• shock• acidosis/hyperlactemia• hypoglycemia• jaundice or other liver malfunctions• renal impairment• high parasitemia (>500,000/mm3)
