NCT00383747

Brief Summary

Patients with schizophrenia have a variety cognitive deficits and nicotine has been shown to normalize some of these deficits. The purpose of this study is to investigate the effects of nicotine on cognition in schizophrenia.We will evaluate the effects of transdermal nicotine compared with placebo for attentional impairments in non-smokers with schizophrenia and controls.

Outcome Measures

Primary Outcomes (1)

  • Effects of Nicotine Patch Compared With Placebo in Non- Smokers With Schizophrenia and Control Groups on Attention Measured by the Continuous Performance Test Identical Pairs Version

    The primary outcome measure was attention as measured by the Continuous Performance Test Identical Pairs (CPT-IP) Version 4.0 (Biobehavioral Technologies, New York, USA), developed for use in patients with schizophrenia and normal controls. In this task, participants were asked to respond when two identical pairs of numbers were presented in sequence by pressing a mouse key as quickly as possible using the dominant hand.The stimuli were presented with increasing cognitive load in successive blocks: two-,three- and four-digit target in the first, second and third block, respectively. Hit reaction time, a standard outcome variables on the CPTIP, is presented here. It was measured 3 hrs after application of the patch

    Visit 1 and visit 2 (separated by an interval of 7-10 days)

Secondary Outcomes (3)

  • Effects of Nicotine Patch Compared With Placebo in Non- Smokers With Schizophrenia and Control Groups on Visual Attention and Cognitive Interference as Measured by Three Card Stroop

    Visit 1 and visit 2 (separated by an interval of 7-10 days)

  • Effects of Nicotine Patch Compared With Placebo in Non- Smokers With Schizophrenia and Control Groups on Letter Number Sequencing

    Visit 1 and visit 2 (separated by an interval of 7-10 days)

  • Effects of Nicotine Patch Compared With Placebo in Non- Smokers With Schizophrenia and Control Groups on Lateralized Psychomotor Speed Measured by the Grooved Pegboard

    Visit 1 and visit 2 (separated by an interval of 7-10 days)
