I see that we have a link to JAMA: Journal of the American Medical Association. I am trying to access the article Imaging Correlates of Memory and Concussion History in Retired National Football League Athletes. The website says I need to be a subscriber in order to access or print this document.
We do not have a subscription to that journal. You will need to place an ILL request using the following link: http://lib.sxu.edu/interlibrary
The complete citation to include is: Strain JF, Womack KB, Didehbani N, et al. Imaging Correlates of Memory and Concussion History in Retired National Football League Athletes. JAMA Neurol. Published online May 18, 2015. doi:10.1001/jamaneurol.2015.0206.
