“…Although deficits are greater in moderate to severe TBI (Schwartz et al, 2003; Catroppa et al, 2008; Yeates et al, 2002), existing research suggests that, relative to uncomplicated mild TBI and typically developing controls, children with complicated mild TBI often evidence impaired episodic memory and cognitive processing along with a diminished ability to manage cognitive interference (Levin et al, 2008). Neurocognitive deficits have been associated with persistent behavior problems and may be related to an impaired ability to regulate attention and emotional reactions (Barkley, 1997; Baum et al, 2010; Catroppa et al, 2008; Morgan & Lilenfeld, 2000
Schwartz et al, 2003). While some investigators have reported that verbal intelligence is negatively affected by neurological insult, such as TBI (Ewing-Cobbs et al, 1997; Verger et al, 2001), others have reported that verbal intelligence can be relatively unaffected when injury occurs later in development (Schmand, Smit, Geerlings, & Lindeboom, 1997; Anderson, Catroppa, Morse, Haritou, & Rosenfeld, 2000), suggesting that measures of verbal intelligence may provide reliable estimates of pre-morbid neurocognitive functioning after injury in adolescence (Lezak, Howieson, & Loring, 2004).…”
