Spontaneous brain fluctuation abnormalities in retired football players
Abstract
BACKGROUND
New measures of the spontaneity of signal amplitudes of low-frequency fluctuations (ALFF) and fractional ALFF (fALFF) present in resting state functional MRI (rsfMRI) may provide useful objective information when applied to concussion. These metrics provide a spatial map of where signal spontaneity departs from normal values to indicate areas of impairment or over-compensation. Former professional American-style football players …
