Abstract

OBJECTIVE: Previous research has shown that dopamine signaling in the limbic striatum is crucial for selecting adaptive, motivated behavior and that disrupted dopamine transmission is associated with impulsive and maladaptive behavior. In humans, positron emission tomography (PET) imaging studies have shown that cocaine dependence is associated with the dysregulation of striatal dopamine signaling, which is linked to cocaine-seeking behavior. The goal of the present study was to investigate whether this association applies to the treatment setting. The authors hypothesized that dopamine signaling in the limbic striatum would be associated with response to a behavioral treatment that uses positive reinforcement to replace impulsive cocaine use with constructive personal goals. METHOD: Prior to treatment, cocaine-dependent subjects underwent two PET scans using [(11)C]raclopride, before and after the administration of a stimulant (methylphenidate), for measurement of striatal dopamine D(2/3) receptor binding and presynaptic dopamine release. RESULTS: Both of the outcome measures were lower in the volunteers who did not respond to treatment than in those who experienced a positive treatment response. CONCLUSIONS: These findings provide insight into the neurochemistry of treatment response and show that low dopamine transmission is associated with treatment failure. In addition, these data suggest that the combination of behavioral treatment with methods that increase striatal dopamine signaling might serve as a therapeutic strategy for cocaine dependence.

  • Cocaine abuse is associated with decreased D2 receptor availability in the striatum compared with controls, first reported in 1990 and confirmed by later studies.

    “The first report was in 1990, where a study showed that cocaine abuse was associated with a decrease in D2 receptor availability in the striatum compared to controls (Volkow et al, 1990), and has been followed by a series of studies confirming this observation”
  • In both studies, treatment responders did not differ from controls in measures of D2 receptor levels or dopamine release.

    “Importantly, in both studies the subjects who responded to treatment did not differ from the control group in measures of D2 receptors levels or dopamine release.”
  • Higher dopamine transmission and D2-dependent dopamine signaling in the nucleus accumbens are associated with greater willingness to work for larger but more effortful rewards.

    “In other words, higher dopamine transmission and D2-dependent dopamine signaling in the nucleus accumbens are associated with greater willingness to work for larger but more effortful rewards, while lower dopamine and D2 receptor activity shifts animal’s choice towards less effortful and smaller immediate rewards (Figure 2).”
  • Treatment-seeking cocaine-dependent subjects with higher D2 receptor levels and higher dopamine release in the ventral striatum responded to contingency management treatment, while those with lower levels did not.

    “The results showed that the cocaine-abusing subjects with higher D2 receptor levels and higher dopamine release in the ventral striatum responded to treatment, while those with lower levels did not (Martinez et al., 2011).”
  • In cocaine abusers, treatment responders had higher socioeconomic status than relapsers and did not differ from controls.

    “the subjects who responded to treatment had a higher socioeconomic status compared to those who relapsed (Barratt Simplified Measure of Social Status: treatment responders 34.1 ± 9.2; non-responders 27.1 ± 4.5, p = 0.01), and actually did not differ from the control group (34.8 ± 7.9, p = 0.8).”

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.
