Modulation of Regional Brain Activation in Schizophrenic Patients by Pharmacological Therapy
This study has been terminated.
Sponsors and Collaborators: University of Jena
Sanofi-Aventis
Information provided by: University of Jena
ClinicalTrials.gov Identifier: NCT00419653
  Purpose

The study aims to investigate the modulation of regional brain activation in schizophrenic patients by psychopharmacological treatment with either haloperidol, amisulpride or olanzapine. The study will be performed with functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI).

Enrollment: 19
Study Start Date: January 2003
Study Completion Date: September 2007
Primary Completion Date: September 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
1: Experimental Drug: Amisulpride
2: Active Comparator Drug: Olanzapine
3: Active Comparator
Haloperidol
Drug: Haloperidol

Detailed Description:

The current study aims to investigate the following issues:

  • Changes in cognitive activation patterns under therapy with the typical neuroleptic haloperidol as compared to the atypical antipsychotics amisulpride and olanzapine
  • Relationship of these changes in activity to psychopathological, neuropsychological and pharmacotherapeutic variables (e.g. drug plasma level) as well as to certain biological markers (HVA, prolactin)
  • Relationship between diffusion anisotropy as an indicator for structural connectivity and cognitive activation patterns under antipsychotic treatment
