Researchers at the University of Minnesota have found that cerebral malaria is related to long-term cognitive impairment in one of four child survivors. The research is published in the current issue of the journal Pediatrics.
Malaria is a leading cause of death for children in sub-Saharan Africa. Cerebral malaria, which affects more than 750,000 children a year, is one of the deadliest forms of malaria. It only takes one bite from an infected mosquito to contract the disease that directly affects the brain, causing fever, vomiting, chills, and coma.
"Children with cerebral malaria recover quite dramatically if they survive the period of coma," said Chandy John, M.D., associate professor of pediatrics at the University of Minnesota and principal investigator of the study. "But before this study, no one had prospectively assessed what happened to their thinking in the years after they had the cerebral malaria episode."
John worked with Michael Boivin, Ph.D., M.P.H., an expert in neuropsychology from Michigan State University, to evaluate cognitive function in children 5-12 years old with cerebral malaria who had been admitted to the Mulago Hospital, Kampala, Uganda. The children were evaluated for cognitive function in three major areas: attention, working memory, and tactile learning. Evaluation was done at hospitalization, six months after the initial malaria episode, and two years after the episode.
