Initial memory deficits and subsequent recovery in two cases of head trauma

This study describes initial and one-year follow-up findings on verbal memory testing of two patients who sustained moderate head injuries. The two main purposes were (a) to capture the specific patterns of memory disorders shown by these two head-trauma patients, and (b) to explore the nature of the recovery of these disorders. Several episodic memory tests and semantic memory tests were employed as well as questions about autobiographical events having occurred prior to and after the trauma, and about various aspects of the accident itself causing the trauma. The main conclusions to be drawn from the study are that the memory disorders demonstrated are based on difficulties in memory organization, and that the two patients differ in the nature of the recovery of the deficits.
