Lateralized cerebral impairment in schizophrenia. A critical review.

The authors review the more recent areas of research in the field of cerebral lateralized dysfunction in schizophrenia. The different approach consistently suggest a definite degree of abnormality in hemispheric functioning in schizophrenic patients: nevertheless, the heterogeneity of patients' populations, as well as some inherent characteristic of the disease (i.e. duration of the illness, length of hospitalization, duration of drug treatment and psychopathological symptoms) should be taken into the account in order to obtain a more accurate definition of the cerebral impairment in schizophrenia.
