Abstract
|
|
|
Currently the cranial computed tomography gained a rising popularity not only because it permits the direct visualization of cerebral infarct but also because it allows the determination of the size and location of infarct.
The author analyzed the results of electroencephalography in 26 patients of supratentorial cerebral infarcts which were confirmed by the cranial computed tomography. The degree of electroencephalographic findings gradually diminished with the passage of time after the infarct. During acute and subacute stage, the electroencephalographic records showed poly￢morphic delta activity in 94% of the subjects involving cerebral white matter and depressive back ground amplitude in 84% of the subjects involving cerebral cortex. And the focal abnormalities of electroencephalography judged by the occurrence of polymorphic delta activity and depressive back ground amplitude were found in 83% of all the subjects during acute and subacute stage.
Therefore we conclude the serial recordings of electroencephalography are also very useful and less expensive tool in evaluating the prognosis and the outcome of cerebral infarct in spite of worldwide use of the computed tomography.
