Abstract

BACKGROUND: Adolescents with conduct and substance problems ("Antisocial Substance Disorder" (ASD)) repeatedly engage in risky antisocial and drug-using behaviors. We hypothesized that, during processing of risky decisions and resulting rewards and punishments, brain activation would differ between abstinent ASD boys and comparison boys. METHODOLOGY/PRINCIPAL FINDINGS: We compared 20 abstinent adolescent male patients in treatment for ASD with 20 community controls, examining rapid event-related blood-oxygen-level-dependent (BOLD) responses during functional magnetic resonance imaging. In 90 decision trials participants chose to make either a cautious response that earned one cent, or a risky response that would either gain 5 cents or lose 10 cents; odds of losing increased as the game progressed. We also examined those times when subjects experienced wins, or separately losses, from their risky choices. We contrasted decision trials against very similar comparison trials requiring no decisions, using whole-brain BOLD-response analyses of group differences, corrected for multiple comparisons. During decision-making ASD boys showed hypoactivation in numerous brain regions robustly activated by controls, including orbitofrontal and dorsolateral prefrontal cortices, anterior cingulate, basal ganglia, insula, amygdala, hippocampus, and cerebellum. While experiencing wins, ASD boys had significantly less activity than controls in anterior cingulate, temporal regions, and cerebellum, with more activity nowhere. During losses ASD boys had significantly more activity than controls in orbitofrontal cortex, dorsolateral prefrontal cortex, brain stem, and cerebellum, with less activity nowhere. CONCLUSIONS/SIGNIFICANCE: Adolescent boys with ASD had extensive neural hypoactivity during risky decision-making, coupled with decreased activity during reward and increased activity during loss. These neural patterns may underlie the dangerous, excessive, sustained risk-taking of such boys. The findings suggest that the dysphoria, reward insensitivity, and suppressed neural activity observed among older addicted persons also characterize youths early in the development of substance use disorders.

Figures

Figure 1 Schematic illustration of dysphoria induced by repeated intoxication-withdrawal cycles. Each intoxication leads to a subjective “high”, with enhanced response to reward due to reduced reward thresholds in medial forebrain bundle. Each acute withdrawal event results in subjective dysphoria with reduced response to reward due to elevated reward thresholds. Frequent cycle repetitions gradually suppress subjective “highs”, deepening dysphoria by further raising reward thresholds. Increasingly, the drug is used to escape dysphoria and achieve normal mood. During abstinence, mood recovers very slowly. (Based on Koob and Volkow [33]).

Figure 2 Colorado Balloon Game. A. Decision-Balloon screen, yellow light illuminated. Counter initially $5. B. Events during presentation of 90 paired trials, each Decision Balloon (DecBa) followed by a Directed Balloon (DirBa). Top: timing (seconds). Colored circles represent stoplight lights. DecBa begins (B, upper): yellow light illuminated 4 sec, subject decides to press left (L) or right (R) button. Green light (0.5 sec), subject executes response. Red light, consequence appears (3.5 sec). Risky right press consequence, either: (a) “smiley face”, expanding balloon, puffing sounds, counter adds 5 cents, or (b) “pop” sound, shrinking balloon, “frowney face”, counter loses 10 cents. Cautious left press consequence: +1 cent on counter, dull “thud” sound, unchanged balloon. Then, “jittered” fixation. DirBa's (B, lower) are identical to their paired DecBa's except: only half of initial yellow light illuminates, signaling (i) start of a DirBa and (ii) button to press during green light (e.g., right illumination – press right) – the same button chosen during preceding paired DecBa. Green-light press on directed button: +2 cents on counter. Then balloon repeats the consequence (puff up, pop, or no change) of previous paired DecBa; subject was told that DirBa consequences would not affect earnings. Finally, jittered fixation screen. C. During DecBa, declining proportion of right presses programmed to win as game progresses. Mostly pressing left later in game saves earnings. D. Visual Analog Scales (VAS). After sessions subjects rated their opinions about the stated questions on 100mm lines. Marked positions represent all-subject means; groups did not differ significantly. Upper VAS: subjects' understanding of decision-making source for DecBa vs. DirBa. Lower VAS: Different emotional responses to puff-ups or pops of DecBa, vs. DirBa. E. Mean numbers, DecBa selections.

Figure 4 DecBa BOLD activity minus DirBa BOLD activity during yellow-light decision periods for patients and controls. Mean DecBa-minus-DirBa values are shown for patients, and separately for controls, in brain regions with significant control-patient differences (see Table 5). Negative deflections in some regions indicate that subjects' mean activity there was less during DecBa than during DirBa. Some regions extend across several anatomical structures. Some structures appear more than once because they contained more than one activated cluster. SPM activation units: see Methods. Abbreviations: Ant, anterior. Gy, gyrus. Med, medial. Pre-SMA, region immediately anterior to the supplementary motor area. Sup, superior.

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.
