What are the functional consequences of neurocognitive deficits in schizophrenia?

Michael Foster Green·1996·American Journal of Psychiatry

Abstract

Objective It has been well established that schizophrenic patients have neurocognitive deficits, but it is not known how these deficits influence the daily lives of patients. The goal of this review was to determine which, if any, neurocognitive deficits restrict the functioning of schizophrenic patients in the outside world. Method The author reviewed studies that have evaluated neurocognitive measures as predictors and correlates of functional outcome for schizophrenic patients. The review included 1) studies that have prospectively evaluated specific aspects of neurocognition and community (e.g., social and vocational) functioning (six studies), 2) all known studies of neurocognitive correlates of social problem solving (five studies), and 3) all known studies of neurocognitive correlates and predictors of psychosocial skill acquisition (six studies). Results Despite wide variation among studies in the selection of neurocognitive measures, some consistencies emerged. The most consistent finding was that verbal memory was associated with all types of functional outcome. Vigilance was related to social problem solving and skill acquisition. Card sorting predicted community functioning but not social problem solving. Negative symptoms were associated with social problem solving but not skill acquisition. Notably, psychotic symptoms were not significantly associated with outcome measures in any of the studies reviewed. Conclusions Verbal memory and vigilance appear to be neces…

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Hippocampus-dependent memory is inversely associated with cortisol levels in individuals diagnosed with schizophrenia.

    “An earlier study reported that hippocampus-dependent memory is inversely associated with cortisol levels in individuals diagnosed with schizophrenia [154] .”
  • Antipsychotics fail to improve cognitive deficits, which are directly linked to poor real-world function.

    “and fail to improve cognitive deficits, which are directly linked to poor real-world function 41 .”
  • A link exists between the neurocognitive deficits associated with schizophrenia and ADHD and multiple areas of functional impairment.

    “a link between the neurocognitive deficits associated with each disorder and multiple areas of functional impairment (Bowie et al., 2006; Green, 1996; Green et al., 2004; Green, Kern, Braff, & Mintz, 2000) provides a useful framework for discussing the potential benefits of combined neurocognitive + skill-based approaches.”

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.
