A Possible Role for the Striatum in the Pathogenesis of the Cognitive Symptoms of Schizophrenia

Open access

Abstract

The cognitive symptoms of schizophrenia are largely resistant to current treatment and are thus a life-long burden of the illness. Studies of cognitive symptoms have commonly focused on prefrontal cortex because of its demonstrated importance for executive function and working memory--key components of the deficit. The role of striatal-cortical circuitry and therefore the striatum itself has received much less attention. Here we review longstanding evidence that the striatum and its cortical connections are critical for complex cognition and discuss emerging evidence of the striatum's potential involvement in cognitive symptoms. Finally, we suggest how mouse models might test ideas about the contribution of early striatal dysfunction to the cognitive symptoms of schizophrenia.

  • In morphometric MRI studies, decreased gray matter in the dorsolateral anterior cingulate cortex and striatum is suggestive of impairment in uncertainty adaptation and decision-making processes.

    “In morphometric MRI studies, decreased gray matter in the dorsolateral anterior cingulate cortex and striatum is suggestive of impairment in uncertainty adaptation and decision-making processes (Baiano et al., 2007; McCutcheon et al., 2019; Simpson et al., 2010).”

    The sections on mouse models and altered subcortical dopamine report reduced frontal gray-matter volume in people at risk for schizophrenia and smaller caudate nuclei in never-medicated patients. “The Striatum Has an Important Role in Cognition” links the striatum to decision-making. The paper does not identify decreased gray matter in the dorsolateral anterior cingulate cortex or link those MRI findings to impaired uncertainty adaptation; page numbers were not available in our copy.

  • The striatum has been highlighted as playing an important role in the pathogenesis of the cognitive symptoms of schizophrenia.

    “Moreover, the striatum has been highlighted as playing an important role in the pathogenesis of the cognitive symptoms of schizophrenia [63].”
  • This mouse model may provide a link explaining how altered mesostriatal and mesolimbic DA receptors and DA transmission can alter cognitive processes in the frontal cortex, possibly by dysregulating circuit pathways linking the striatum and prefrontal cortex.

    “this mouse model may provide a link explaining how altered mesostriatal and mesolimbic DA receptors and DA transmission can alter cognitive processes in the frontal cortex, possibly by dysregulating circuit pathways that link connectivity between the striatum and pre-frontal cortex [381].”

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.
