title: [A study of reaction time in 120 patients with brain tumor, traumatic intracranial hematoma, cerebrovascular disease and epilepsy].
abstract: A study of the simple reaction time (SRT) and choice reaction time (CRT) in 120 patients classified into 4 groups with brain tumor, traumatic intracranial hematoma, cerebrovascular disease (CVD) and epilepsy respectively was reported. The results were summarized as follows. 1. The SRT in the 4 groups were all significantly prolonged as compared with normal subjects. 2. Among the four groups, the CVD group revealed the most severe disfunction, while the epilepsy group showed the least. 3. There was a positive correlation between the extent of the cerebrovascular lesion and the prolongation of type SRT. 4. Lesions in the basal ganglia might also cause a delay of the occurrence of the reaction. 5. Lesions involving both the frontal and parietal lobes resulted in remarkably longer reaction time than those in other cerebral regions. 6. The phenomenon of lateralization of the brain function was not reflected in the SRT and CRT of the four groups of the examined patients.
