Summary

Atypical neuroleptics like risperidone and clozapine improved selective attention in schizophrenia patients. These medications did not harm cognitive function, showing a positive impact on patient performance.

Area of Science:

  • Neuroscience
  • Psychiatry

Context:

  • Schizophrenia is a chronic mental disorder.
  • Cognitive deficits, particularly in selective attention, are common in schizophrenia.
  • Atypical neuroleptics are standard treatments, but their cognitive effects require investigation.

Purpose:

  • To investigate the impact of six-month treatment with risperidone or clozapine on selective attention in chronic schizophrenia patients.
  • To compare patient performance with a general population group.

Summary:

  • 17 schizophrenia patients underwent selective attention tasks before and during treatment with risperidone or clozapine.
  • Performance was assessed using a visual search task measuring reaction times and error rates.
  • Results indicated improved selective attention over time, with no deleterious effects from atypical neuroleptics.
