Discarding data from subjects with multiple sclerosis who exhibit head movement during functional magnetic resonance imaging may bias sampling away from subjects with lower cognitive ability, new research has shown. Because head movement during fMRI degrades data quality, data associated with severe movement is frequently discarded as a source of random error, and these authors note that it is important for researchers to be aware of this potential bias.
