Rethinking schizophrenia

Insel, Thomas R.·2010·Nature

Abstract

How will we view schizophrenia in 2030? Schizophrenia today is a chronic, frequently disabling mental disorder that affects about one per cent of the world's population. After a century of studying schizophrenia, the cause of the disorder remains unknown. Treatments, especially pharmacological treatments, have been in wide use for nearly half a century, yet there is little evidence that these treatments have substantially improved outcomes for most people with schizophrenia. These current unsatisfactory outcomes may change as we approach schizophrenia as a neurodevelopmental disorder with psychosis as a late, potentially preventable stage of the illness. This 'rethinking' of schizophrenia as a neurodevelopmental disorder, which is profoundly different from the way we have seen this illness for the past century, yields new hope for prevention and cure over the next two decades.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • An analysis of 22 screenings found 98 duplications in 36,676 SZ patients (0.26%) and only 12 duplications in 48,331 controls (0.025%), indicating a 10.79-fold increase in SZ risk.

    “An analysis of 22 screenings in various populations found 98 duplications in 36,676 SZ patients (0.26%), with only 12 duplications in 48,331 controls (0.025%), indicating a 10.79-fold increase in risk for developing SZ [43].”
  • Psychosis is not the onset of schizophrenia, but rather a prominent consequence of a developmental path toward schizophrenia that can be perhaps prevented through early intervention.

    “According to this view, psychosis is not the onset of the disorder, but rather a prominent consequence of a developmental path toward schizophrenia that can be perhaps prevented through early intervention 44 .”
  • Schizophrenia is increasingly viewed as a neurodevelopmental disorder involving brain circuit alterations, including dysfunction of parvalbumin-positive fast-spiking GABA neurons.

    “Schizophrenia is increasingly recognized as a neurodevelopmental disorder that involves alterations in brain circuits, including dysfunction of parvalbumin (PV)-positive, fast-spiking GABA neurons (1, 2).”
  • Mis-timed developmental trajectories of brain plasticity may contribute in part to the etiology of mental illnesses involving oxidative stress, such as schizophrenia.

    “Mis-timed developmental trajectories of brain plasticity may therefore contribute in part to the etiology of mental illnesses involving oxidative stress, such as schizophrenia (2, 3, 18).”
  • Several molecular brakes relevant to schizophrenia, other than PNNs, limit critical period plasticity, including myelin signaling through NgR-PirB and dampened nicotinic receptor signaling by Lynx1.

    “Several molecular brakes of relevance to schizophrenia (other than PNNs) have been identified to limit critical period plasticity, including myelin signaling through a NgR-PirB complex (2, 74, 75) or dampened nicotinic receptor signaling by Lynx1 (29, 76).”

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.
