SNMMI: SPECT shows brain changes in football players

June 13, 2017

SPECT scans show changes in cerebral blood flow in retired professional football players that differ based on which position they played, according to researchers from the University of California, Los Angeles (UCLA). The findings were presented on Monday at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) meeting.

More specifically, spatial ability among former offensive linemen was related to left associate cortical blood flow, while the spatial ability of former defensive backs was associated with right posterior cingulate cortical blood flow. Those and other differences between the on-the-field positions could be related to the severity of concussions or traumatic brain injuries experienced by the players during their careers.
