Objective
Stroke and traumatic brain injury lead to cognitive, neurological disorders, which can result in many difficulties at daily living. The purpose of this study is to investigate the difference in treatment results between stroke and traumatic brain injury.
Methods
Sixty-one adults with brain damage were recruited retrospectively in this study. Thirty-three people who had suffered from stroke and 28 from traumatic brain injury(TBI) were involved. Before and after computer-assisted cognitive rehabilitation, all participants were assessed their cognitive function using Computerized Neuropsychological Test(CNT, Version 4.0, Maxmedica). Computerized Neuropsychological Test is composed of 6 components; verbal memory, visual memory, attention, visuo-motor coordination and high cognition tests. All participants were received 30 sessions of computer-assisted cognitive rehabilitation(Comcog, Maxmedica), five times per week. Each sessions were proceed for 30minutes. The comparison of treatment effects were statistically analyzed using SPSS.
Results
Before cognitive rehabilitation, there was no significant difference between the two groups in each contents of CNT. After treatment, considering all patients as one group, people showed improvement in almost all CNT contents.
Comparing the results between two groups, All components except visual learning test and word color test were improved in the stroke patients. Meanwhile, in the TBI patients, there was no significant difference between before and after treatment at digital span backward, auditory CPT, visual CPT, and card sorting test.
Conclusions
Computer-assisted cognitive rehabilitation is widely used tool for patients with cognitive impairments. According to present study, in contrast to stroke patients, TBI patients didn’t show significant difference before and after treatment at the digital span backward, auditory CPT, visual CPT, and card sorting test. These components are related to ability regarding attention, inhibition, and high cognition, and are thought to be deeply associated to the frontal region of the brain. Traumatic brain injury, which can cause diffuse injury to the brain, is more likely to cause damage to the frontal area than stroke is. Consequently, response to cognitive rehabilitation shows different patterns.
