Abstract/OtherAbstract:
BACKGROUND: We have previously demonstrated that putaminal but not caudate volumes are associated with poor outcome in patients with chronic schizophrenia. Present longitudinal study was designed to investigate progressive differences in striatal volumes among chronic schizophrenia patients with different outcomes and healthy subjects. METHODS: Structural MRI scans were acquired at baseline and at follow-up four years later to evaluate volumetric changes in 26 poor-outcome schizophrenia patients, 23 good-outcome patients and 16 healthy subjects. RESULTS: Schizophrenia patients with different outcomes entered the study with similar volumes of the caudate nucleus and putamen. The rate of decline in volumes of the putamen was greater in patients with poor outcome than in the good-outcome group, so that their putaminal but not caudate volumes were significantly smaller at the time of follow-up. There were no differences in baseline and follow-up volumes of the putamen or in the rate of their progression among patients with schizophrenia and healthy comparison subjects. The caudate volumes were lower in schizophrenia patients than healthy subjects at baseline and follow-up, but showed no differential patterns of progression between the groups. CONCLUSIONS: Volumes of the putamen may represent a longitudinal marker of treatment responsiveness and outcome in patients with chronic schizophrenia.
