With today’s headlines awash with tales of measles and the Ebola virus, it can be easy to forget that malaria, an infectious disease caused by the protozoan parasite Plasmodium falciparum, remains one of the most deadly diseases on the planet. According to the World Health Organization, more than 600,000 people died of malaria in 2012—the majority attributed to the most severe form of the disease, cerebral malaria. One of malaria’s biggest mysteries is why some people develop the cerebral form of the disease, in which the malarial parasites invade the blood vessels around the brain, and then recover, while others with this form, many of them young children, will die of the infection.

In 2008, I spoke with Terrie Taylor, DO, about her clinical work with cerebral malaria patients in Malawi. She explained how cerebral malaria is a “tricky disease,” but was optimistic that researchers would have a clearer picture of how Plasmodium falciparum occupy the brain’s blood vessels in five to ten years. One of her most important goals was to understand what might be different in the brains of those who died of the disease from those who survived. Now, eight years after my Cerebrum story “Cerebral Malaria: A Wily Foe” was published, Taylor and colleagues have published a groundbreaking neuroimaging study in the New England Journal of Medicine highlighting one of those key differences.
