Methamphetamine-Related Psychiatric Symptoms and Reduced Brain Dopamine Transporters Studied With PET
Abstract
OBJECTIVE: A positron emission tomography (PET) study has suggested that dopamine transporter density of the caudate/putamen is reduced in methamphetamine users. The authors measured nucleus accumbens and prefrontal cortex density, in addition to caudate/putamen density, in methamphetamine users and assessed the relation of these measures to the subjects' clinical characteristics. METHOD: PET and 2-beta-carbomethoxy-3beta-(4-[(11)C] fluorophenyl)tropane, a dopamine transporter ligand, were used to measure dopamine transporter density in 11 male methamphetamine users and nine male comparison subjects who did not use methamphetamine. Psychiatric symptoms in methamphetamine users were evaluated by using the Brief Psychiatric Rating Scale and applying a craving score. RESULTS: The dopamine transporter density in all three of the regions observed was significantly lower in the methamphetamine users than the comparison subjects. The severity of psychiatric symptoms was significantly correlated with the duration of methamphetamine use. The dopamine transporter reduction in the caudate/putamen and nucleus accumbens was significantly associated with the duration of methamphetamine use and closely related to the severity of persistent psychiatric symptoms. CONCLUSIONS: These findings suggest that longer use of methamphetamine may cause more severe psychiatric symptoms and greater reduction of dopamine transporter density in the brain. They also show that the dopamine transporter reduction may be long-lasting, even if methamphetamine use ceases. Further, persistent psychiatric symptoms in methamphetamine users, including psychotic symptoms, may be attributable to the reduction of dopamine transporter density.

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.
