This study confirms earlier findings of a relationship between cerebral blood flow and concussive symptoms.
Persistent physiologic symptoms after concussion, according to one theory, are caused by relative reduced cerebral blood flow (CBF) and hypermetabolism (Neurology 2014; 83:1). These researchers prospectively followed 44 collegiate football players, 17 of whom experienced concussion. CBF imaging and cognitive, depressive, and anxiety evaluations were performed in all participants. CBF was imaged in concussed athletes approximately 1 day, 1 week, and 1 month postconcussion.
As expected, cognitive symptoms resolved at 1 week, and neuropsychiatric symptoms at 1 month. CBF in the right dorsal midinsular cortex (dmIC) and superior temporal cortex was lower in concussed than healthy athletes but recovered by 1 month. Slower recovery was associated …
