Abstract
In order to determine whether the occurrence of extrapyramidal symptoms may affect how we estimate the intensification of depressive and negative symptoms in schizophrenia, 66 inpatients diagnosed with paranoid schizophrenia (according to the criteria DSM-III-R and ICD-10) were examined with the use of the scales: CDS, BDI, BPRS, SANS and SAS. No relationships have been observed between the level of extrapyramidal symptoms and self-rating of depression, with the existence of few correlations with observer report scales. The most numerous relationships were recorded with the symptoms of the subscales Apathy/Avolition and Affective Flattening and extrapyramidal symptoms.
