Linguistic abilities in patients with prefrontal damage.
The language abilities of 21 patients with prefrontal lesions (11 right and 10 left) and 15 matched normal subjects were analyzed, using a linguistic ability test designed to evaluate performance in six areas: automatic language, language production, verbal memory, syntax, derivative words, and comprehension of logical grammatical structures. Significant differences in the obtained scores of all groups were found. In spite of formal conservation of language in patients with frontal damage, their complex and conceptual verbal abilities were severely compromised.
