The temporal lobe is essential in saving declarative memory and plays an important role along with the cerebral neocortex in creating and maintaining long-term memory. Damage to the temporal lobe is expected to result in cognitive impairment or dementia, which has characteristic symptoms such as cognitive and behavioral dysfunction and decreasing self-reliance in activities of daily living. We report on a patient, who suffered from dementia due to meningovascular syphilis affecting the medial temporal lobe, and on the outcome of cognitive rehabilitation.

Method: Fifty subjects with brain injury were enrolled and classified into two groups, experimental (n=25) and control group (n=25). Control group received conventional reha bilitation therapy including physical and occupational therapy. Experimental group received additional computer- assisted cognitive training using CogRehabKⰒ software consisted of 10 level-completing programs, 3 times per week, 30 minutes per session, for 4 to 6 weeks. All patients were assessed their cognitive functions using Seoul Computerized Neuropsychological Test (SCNTⰒ, Maxmedica, 2001), minimental status examination (MMSE), digit span, and Wechsler memory scale before and after treatment. Functional independence measure and geriatric depression scale were also applied for evaluation of functional and mood status.
Results: Before the treatment, two groups showed no difference in their cognitive functions. After 4 to 6 weeks of treatment, the experimental group showed significantly higher performance in forward digit span, forward visual span, auditory continuous performance test, and visual continuous performance test in CNT and MMSE than control group (p＜0.05).
Conclusion: We conclude that the CogRehabKⰒ may be useful as an additional tool for the cognitive rehabilitation in patients with brain injury. (J Korean Acad Rehab Med 2003; 27: 830-839)
Method: Ten memory training programs, which included verbal/non-verbal, sequential/ non-sequential, and visual/auditory memory properties were designed and converted to the computer program using C-language. The training program included various aspects of memory such as spatial memory, sequential verbal and nonverbal recall, associated recall, categorical memory, and integrated semantic memory. Each program used familiar pictures and sounds in our living situation to give the patients comfortable feelings and interests. Seven patients with brain injury were trained using the computer-assisted memory program 3 times per week for 4 weeks. All patients were assessed their cognitive function using Seoul Computerized Neuropsychological Test (Maxmedica) before and 1 month after the treatment.
Results: Ten computer-associated memory training programs using C-language were successfully developed. The patients who were trained with computer-assisted memory programs showed higher performances in forward digit span, backward digit span, backward visual span, verbal learning, visual controlled continuous performance, auditory controlled continuous performance, and finger tapping tests after than before the treatment.
Conclusion: The computer-assisted memory training can be used as an additional tool for memory rehabilitation in patients with brain injury.
