Abstract

Increasing evidence indicates that substance-dependent individuals (SDI) are impaired in executive control tasks relying on different systems within the prefrontal cortex (PFC). Three different functional systems have been described: the dorsolateral prefrontal cortex (DLPC), orbitofrontal cortex (OFC), and anterior cingulate cortex (ACC) circuits. Dysfunction within each PFC system is associated with different behavioral, cognitive, and emotional abnormalities. Few studies have conducted an exhaustive examination of all these different factors in SDI. In this study, SDI (including alcohol, cocaine, and methamphetamine polysubstance users, n=35) were compared with healthy controls (n=36) on a series of behavioral (Frontal Systems Behaviour Scale, FrSBe), cognitive (N-back, Go-No Go, and Wisconsin Card Sorting Tasks), and emotional (International Affective Picture System, IAPS) tasks, each of which was thought to tax a different component of these PFC functional systems. SDI showed greater behavioral problems in the apathy, disinhibition, and executive dysfunction subscales of the FrSBe. Behavioral deficits were significantly associated with several real-life domains in which SDI typically have problems. SDI also showed poorer performance on cognitive tests of working memory, response inhibition and mental flexibility, and abnormal processing of affective images from the IAPS. Cognitive, behavioral, and emotional measures were moderately correlated.

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.
