[The disorder of space analysis as a key to understanding anosognosia in right-sided cerebral infarct].

The dextrocerebral stroke is often underestimated as a result of its deficits--in contrary to the left cerebral stroke with the aphasia--because the patient's neglect of the plegic side is transferred to the therapist. A key to understanding this is the hypothesis that the anosognosia results in a loss of spatial analysis. After a survey of the different functions of the left and right hemispheres the author demonstrates the symptoms, diagnosis and therapeutic prognoses. The therapy needs to be continued for several months. In addition, the patient's social environment is important.
