| Summary: | Introduction. Neuropsychological aspects of paranoid schizophrenia have still
not been examined enough. These disorders are usually not studied separately,
but are included in the studies about schizophrenic patients with positive
symptoms. Despite the fact that schizophrenia represents a heterogeneous
group of mental disorders, usually it is not separated from schizoaffective
disorder in neuropsychological researches. Objective. The essence of this
research is to evaluate cognitive functioning of patients with paranoid
schizophrenia and schizoaffective disorder by applying neuropsychological
tests. Methods. The research included 91 subjects, right handed, from 30 to
53 years old, who were classified into three groups: inpatients with paranoid
schizophrenia in remission (n=31), inpatients with schizoaffective disorder
in remission (n=30) and healthy subjects (n=30). Results. Both groups of
patients showed poorer achievements than healthy subjects in most of the
applied tests. Patients with schizoaffective disorder showed global loss of
intellectual efficiency, executive dysfunction and compromised
visual-construction organization. Patients with paranoid schizophrenia
expressed partial loss of intellectual efficiency with verbal IQ and
executive functions preserved. Conclusion. In the remission phase, patients
with paranoid schizophrenia expressed cognitive disorders in moderate degree,
but when it comes to patients with schizoaffective disorder, more massive
cognitive deficits were registered. |
