Abstract

Meta-analyses of genome-wide association study data have begun to lead to promising new discoveries for behavioral and psychiatrically relevant phenotypes (e.g., schizophrenia, educational attainment). We outline how this methodology can similarly lead to novel discoveries in genomic studies of substance use disorders, and discuss challenges that will need to be overcome to accomplish this goal. We illustrate our approach with the work of the newly established Substance Use Disorders workgroup of the Psychiatric Genomics Consortium.

  • The presence of a psychiatric disorder, including mood, anxiety, psychotic and personality disorders, and ADHD, is associated with an increased risk for SUDs.

    “The presence of a psychiatric disorder - including mood, anxi ety, psychotic and personality disorders, and ADHD - is associ ated with an increased risk for SUDs.”

    From Substance use disorders: a comprehensive update of classification, epidemiology, neurobiology, clinical aspects, treatment and prevention (2023) · cites this paper as [121]

    The Comorbidity section (page not provided) says SUDs commonly co-occur with other psychiatric illnesses and gives major depressive disorder as an example. It does not establish that the presence of each listed disorder—mood, anxiety, psychotic and personality disorders, and ADHD—is associated with increased SUD risk. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • The association between psychiatric disorders and SUDs likely reflects bidirectional links, such that having a mental disorder increases risk of maladaptive drug use to self-medicate, and having a SUD increases risk for developing a mental disorder, as drugs affect neurocircuits relevant to other mental disorders.

    “These associations are likely to reflect bidirectional links, such that hav ing a mental disorder increases risk of maladaptive use of drugs to self- medicate, and having a SUD increases risk for developing a mental disorder, as drugs affect neurocircuits relevant to other mental disorders.”

    Experimental — accuracy not yet measured
  • Common genetic and environmental risk factors for both SUDs and mental disorders contribute to their high degree of comorbidity.

    “Common genetic and environmental risk fac tors for both SUDs and mental disorders also contribute to their high degree of comorbidity 121- 123 .”

    From Substance use disorders: a comprehensive update of classification, epidemiology, neurobiology, clinical aspects, treatment and prevention (2023) · cites this paper as [121]

    The “(c) Comorbidity” section (page not provided) says SUDs commonly co-occur with psychiatric illnesses and that some of this comorbidity is attributable to shared genetic effects. It does not say that shared environmental risk factors contribute to their comorbidity; its discussion of environmental effects concerns SUDs generally. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • SUDs are associated with an increased risk for a mental disorder.

    “On the other hand, SUDs are also associated with increased risk for a mental disorder.”

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.
