Background: The main purpose of this study was to assess possible modifications of cognitive performance among schizophrenia patients treated with long-acting injectable antipsychotics (LAIs) of second generation anti-psychotics (SGAs). Our hypothesis is that the shift from the oral formulation to the LAI formulation of SGAs drugs improves the cognitive performance. The secondary objective was to carry out a head to head comparison of two different SGA-LAI treatments [i.e., 1-month Paliperidone Palmitate (PP1M), monthly Aripiprazole (Ari-LAI)] in our study with an independent and real-world setting. Methods: The sample comprised 32 participants who were consecutively recruited over 12 months. Seventeen patients treated with Ari-LAI and 10 treated with PP1M completed psychopathological, neuropsychological and functional assessments. Group differences were explored through chi-squared and t-tests, as appropriate. GLM Repeated Measures were used to study variations of cognitive performance along 12 months and to test differences between drugs. Results: We found an effect of time on the outcomes investigated but this did not depend on the type of LAI used.

Abstract

Background: The main purpose of this study was to assess possible modifications of cognitive performance among schizophrenia patients treated with long-acting injectable antipsychotics (LAIs) of second generation anti-psychotics (SGAs). Our hypothesis is that the shift from the oral formulation to the LAI formulation of SGAs drugs improves the cognitive performance. The secondary objective was to carry out a head to head comparison of two different SGA-LAI treatments [i.e., 1-month Paliperidone Palmitate (PP1M), monthly Aripiprazole (Ari-LAI)] in our study with an independent and real-world setting. Methods: The sample comprised 32 participants who were consecutively recruited over 12 months. Seventeen patients treated with Ari-LAI and 10 treated with PP1M completed psychopathological, neuropsychological and functional assessments. Group differences were explored through chi-squared and t-tests, as appropriate. GLM Repeated Measures were used to study variations of cognitive performance along 12 months and to test differences between drugs. Results: We found an effect of time on the outcomes investigated but this did not depend on the type of LAI used. Conclusions: In comparison with the previous oral treatment with SGAs, patients showed a significant improvement in neurocognitive function after 12 months of treatment with SGA-LAI.
