Abstract

The purpose of this study was to examine the change of dopamine transporters (DAT) binding in methamphetamine (METH) abusers in a two-week period of abstinence and its association with cognitive function. Seven healthy subjects and seven METH abusers were recruited. At baseline conditions, the values of specific uptake ratio (SUR) of DAT binding measured by single photon emission computed tomography were lower in METH abusers than in controls. After a two-week period of abstinence, DAT binding was partially recovered and there were no statistic differences in SUR between METH abusers and controls. There was a borderline correlation between the changes of DAT binding in the right, but not the left, striatum and the %Error of Wisconsin Card Sorting Test. These findings indicate that DAT binding in METH abusers can be reversed in a short period of abstinence. The recovery of DAT binding was asymmetric and possibly parallel with the improvement of cognitive function.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Methamphetamine abusers show a consistent and long-lasting decrease in the dopamine transporter, the main target of methamphetamine.

    “Alternatively, studies in methamphetamine abusers show a consistent and long lasting decrease in the dopamine transporter, which is the main target of this drug (Chou et al., 2007; Johanson et al., 2006; McCann et al., 1998; McCann et al., 2008; Sekine et al., 2001; Volkow et al., 2001b).”

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.
