Reduced cerebral blood flow and N-acetyl aspartate in a murine model of cerebral malaria

Cerebral malaria is an important cause of morbidity and mortality in many parts of the world. It has been suggested that cerebral malaria is associated with reduced perfusion due to the blockage of blood vessels by parasitized erythrocytes; although, no quantitative validation of this has been done. We infected C57BL/6 mice with the ANKA strain of Plasmodium berghei and on day 6 of infection we investigated alterations in brain function using arterial spin labeling MRI and proton MRS. MR images did not demonstrate signs of damage. However, there was a significant reduction in cerebral blood flow (P
