FURTHER CHARACTERIZATION OF THE EXECUTIVE MEMORY IMPAIRMENT FOLLOWINGFRONTAL-LOBE LESIONS

In this article we describe a 41-year-old man who, following an operat ion to repair a ruptured anterior communicating artery aneurysm, manif ested the ''hallmark'' features of a dysexecutive memory impairment. O f particular note was the patient's apparently normal level of recogni tion memory but impaired recall on tasks matched for difficulty in con trol subjects. However, further testing revealed that the patient's re cognition memory was not normal under all circumstances. Implications of these data for the interpretation and further investigation of the dysexecutive deficit are discussed. (C) 1994 Academic Press, Inc.
