ABSTRACT
OBJECTIVE:
To assess cognitive functioning in adolescents (12-17 years old) with schizophrenia during open-label treatment with paliperidone extended-release (pali ER).METHODS:
In this exploratory analysis, adolescents treated with pali ER (oral, flexibly dosed, 1.5-12 mg/day) underwent cognitive assessments at baseline and month 6 using a battery of cognitive tests validated in adolescents. Correlation analysis was used to explore the relationship between cognitive assessments and clinical symptoms (Positive and Negative Syndrome Scales [PANSS] and factors) and functionality (Children Global Assessment Scale [CGAS]) at baseline and at 6 months.RESULTS:
A total of 324 of 393 patients had evaluable neurocognitive data. Changes in cognition function tests from baseline to endpoint were generally small to modest, with improvement noted for most cognitive domains (motor speed, attention/working memory, verbal learning and memory, social cognition, speed of processing, executive functioning). No improvement was noted for visual learning and memory. At baseline, there were modest negative correlations between disorganized thoughts and most cognitive domains; these correlations persisted at 6 months. Other significant negative correlations at 6 months were between speed of processing and PANSS total score, positive symptoms, negative symptoms and uncontrolled hostility (p < 0.05). At 6 months, higher CGAS scores (improved functioning) positively correlated with speed of processing and executive functioning, especially among pali ER responders.CONCLUSIONS:
In this large sample of adolescents with schizophrenia, frank cognitive deficits across multiple domains were observed. Treatment with pali ER over 6 months did not worsen neurocognitive functioning and was possibly associated with positive improvement in certain domains.
