Abstract

Rationale High blockade of dopamine D2 receptors in the ventral striatum including the nucleus accumbens may interfere with reward anticipation and cause secondary negative symptoms such as apathy or anhedonia. This may not be the case with newer neuroleptics such as olanzapine, which show less dopamine D2 receptor blockade and a faster off-rate from the receptor.Objectives We used functional magnetic resonance imaging to assess the blood oxygenation level dependent response in the ventral striatum of schizophrenics medicated with typical neuroleptics (T1) and after switching them to olanzapine (T2) and of healthy control subjects at corresponding time points during reward anticipation.Materials and methods Ten schizophrenics, while medicated with typical neuroleptics (T1) and after having been switched to olanzapine (T2), and ten matched healthy volunteers participated in a monetary incentive delay task, in which visual cues predicted that a rapid response to a subsequent target stimulus would either result in monetary gain or have no consequence.Results During reward anticipation, healthy volunteers showed significantly higher ventral striatal activation compared to schizophrenic patients treated with typical neuroleptics but not olanzapine, which was reflected in a significant interaction between group and session. In patients treated with typical neuroleptics, but not with olanzapine, decreased left ventral striatal activation was correlated with negative symptoms.Conclusions Failure to activate the ventral striatum during reward anticipation was pharmacologically state-dependent and observed only in patients treated with typical neuroleptics but not with olanzapine, which may indicate that this drug did not induce secondary negative symptoms via interference with reward anticipation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
