Scholarcy highlights

  • Cognitive impairments are a core feature of schizophrenia and a major determinant of poor functional outcome
  • Because of the history of clinical NP test development, with a focus on broad sensitivity to impairment, the standard NP tests chosen for the MATRICS Consensus Cognitive Battery are likely to be limited in their sensitivity to specific cognitive functions mediated by discrete neurobiological processes
  • In addition to the MCCB and SCoRS, cognition was assessed by two tests that have been found to activate prefrontal cortical function, the AX-Continuous Performance Task and N-back, as a pilot study found that patients receiving MK-077 showed improvement on these measures
  • The cognitive neuroscience measures investigated in this study are more time-consuming and burdensome than standard neuropsychological tests
  • AX-CPT tests were flagged for review if any of the following were true: the participant failed to respond to 20% or more of trials, missed all BX trials, missed > 25% of BY trials or failed to score significantly above chance on AX trials
  • The current study addresses the feasibility and psychometric properties of the AX-CPT and N-Back in a multi-site trial, we did not observe an effect of the investigational drug
