Effects of Subconcussive Head Trauma on the Resting State Default Mode Network

Although less severe, subconcuussive impacts happen more frequent and research suggests they may lead to neurological impairment later in life. Here we investigated the acute effects that subconcussive head trauma may have on the default mode network of the brain and whether or not this may be modulated by history of previous concussion. 24 current collegiate rugby players were recruited and underwent resting-state functional magnetic resonance imaging. Scanning took place before and after a full contact game. Increased connectivity was seen between pregame and postgame scans. Even an acute exposure to subconcussive impacts is enough to alter brain functional connectivity.
