Cognitive deficits in patients with unilateral war-related frontal lobe lesions

The findings of this study may be summarized as follows: (1) No significant general cognitive impairment occurred in S samples with unilateral frontal lobe lesions; (2) Impairment of cognitive performance was greater in Ss with lesions posterior to the Fissure of Rolondo than in well-matched Ss with frontal lobe lesions; (3) Specific cognitive deficits are infrequent in Ss with frontal lobe lesions; (4) No significant differential impairment of cognitive performance was associated with hemispheric lateralization of frontal lesions; and (5) No significant differential impairment of verbal and nonverbal performance was associated with hemispheric lateralization of frontal lesions.
