Effects of Alcohol Dependence Severity on Neural Correlates of Delay Discounting

Lim, Aaron C., Cservenka, Anita, Ray, Lara A.·2017·Alcohol and Alcoholism

Abstract

AIMS: The current study examines the relationship between alcohol dependence severity and delay discounting neural activation. METHODS: Participants (N = 17; 6 female) completed measures of alcohol use and severity and a functional magnetic resonance imaging version of a delay discounting task. RESULTS: Alcohol dependence severity was negatively associated with activation in superior frontal gyrus during impulsive relative to delayed decisions, and positively associated with activation in paracingulate gyrus and frontal pole in delayed relative to impulsive decisions. CONCLUSIONS: These results indicate that alcohol dependence severity tracks closely with dysregulations in cognitive control and reward evaluation areas during impulsive and delayed decisions, respectively. Delay discounting may be a useful construct in capturing these cognitive dysregulations as alcohol use disorders become more severe. SHORT SUMMARY: Among alcohol-dependent individuals, alcohol dependence severity is associated with overactivation of ventromedial prefrontal areas during delayed and underactivation of dorsolateral prefrontal regions during impulsive reward decisions.

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.
