This imaging study from the USA examines the differences in MRI
appearances between Caucasian Americans and African Americans with MS
which might explain the more aggressive form of the disease seen amongst
African Americans. The authors found that there was no significant
difference between the two ethnic groups in global and regional brain
volumes but the lesion volume in African Americans was significantly
greater. The authors therefore conclude that higher lesion accumulation
rather than loss of brain volume is likely to account for the more rapid
disease progression in African Americans.
