This study was to investigate the intelligence and memory disturbance of patients with traumatic brain injury. The fifty-one subjects were the patients finally diagnosed to one of the following four groups by DSM-Ⅳ(APA, 1994) criteria: Mental Disorder Not Otherwise Specified Due to Head Trauma(NOS), Postconcussional Disorder(PD), Amnestic Disorder Due to Head Trauma(AD) or Dementia Due to Head Trauma(DD). Then the K-WAIS scores and Rey-Kim Memory Test scores were compared among diagnostic groups. In addition, the scores of fourteen patients diagnosed to Adjustment Disorder(ADD) were compared to those of traumatic brain injury patients. The results are as follows. In ADD group, almost cognitive functions were maintained. And in DD group, almost all cognitive functions were impaired. In AD groups, because of memory impairment, the cognitive functions related to registration, retention and retrieval of information were impaired. In PD group and NOS group, the cognitive functions which are not affected by brain injury were maintained, but the cognitive functions which needs information processing and higher mental processing were impaired. Finally, the results were discussed and the implications for future studies were suggested.
