OBJECTIVE: To assess the possibilities of influencing the severity of negative disorders in schizophrenic patients with cholinesterase blockade.
MATERIAL AND METHODS: The study included stable 26 patients (13 of them women), average age 40.4 (SD 11.7) with paranoid schizophrenia, episodic form according to ICD-10). All patients received antipsychotic therapy, which was not changed at least for 2 months. We used psychometric scales (Positive and Negative Syndrome Assessment Scale (PANSS), Global Functioning Scale (GAF), neurocognitive techniques (Brief Assessment of Cognition in Schizophrenia-BACS), projective psychological techniques (Rorschach test).
RESULTS AND CONCLUSION: The results of the study showed that augmentation of maintenance antipsychotic therapy with a cholinesterase blocker (ipidacrine at a dose of 20 mg per day) had positive impact on negative symptoms, decreasing the severity of emotional deficiency. The positive changes of cognitive impairment, measured with BACS, occurred regardless of changes in the severity of negative disorders, measured with PANSS. The Rorschach test showed an improvement in the conventional orientation of the patients' thinking. No exacerbation of psychotic symptoms was registered.
