PURPOSE: Cognitive dysfunctions with stroke of the brain stem are rare. We focused on and examined cognitive dysfunction after pontine hemorrhages.
OBJECT AND METHOD: After July 2008, we treated 23 patients with pontine hemorrhages. Only 10 patients were included, all other patients had old hemorrhages, venous anomalies, and disturbances of consciousness. The patients included six men and four women, aged 51 years to 86 years old. The volume of hematoma was 0.11-5.20mL(average:1.74mL);there were six right side, two left side, two bilateral, three ventral, and seven dorsal hematomas. We performed neuropsychological tests such as mini-mental state examination(MMSE), Raven's coloured progressive matrices(RCPM), and frontal assessment battery(FAB).
RESULT: Eight cases had an abnormal score on the tests. The volume of hematoma showed a high negative correlation with MMSE scores(p=0.0194)and RCPM(p=0.0338). On the other hand, the volume of hematoma and FAB scores(p=0.0832)were uncorrelated, and the localization of the hematoma did not correlate with tests of cognitive function.
CONCLUSION: Cognitive dysfunction is not rare after pontine hemorrhage. Therefore, for patients with infratentorial lesions, it is necessary to perform detailed cognitive functional tests.
