“…However, deficits in recalling complex visual patterns have been reported following severe TBI (sTBI), particularly in the acute phase ( Anderson and Catroppa, 2007 ), and deficits in recalling the spatial locations of visual patterns have been reported following mild TBI (mTBI) ( Chuah et al, 2004 ). In general, however, TBI-related deficits in working memory appear to be more evident on verbal than visuospatial tasks ( Anderson and Catroppa, 2007 ; Livengood et al, 2010 ), consistent with recent studies that find greater verbal than visuospatial memory deficits among veterans with mTBI and comorbid post-traumatic stress disorder (PTSD) ( Vasterling et al, 2006 ; Sozda et al, 2014 ).…”
