Résumé : | Severity of opioid dependence, and performance on two successive runs of the Wisconsin Card Sorting Test (WCST), were assessed in 39 right-handed male and female methadone patients who had been randomly assigned to either a recently dosed (n=21) or 24 hr abstinent (n=18) condition. Results indicated that severity of opioid dependence was positively correlated with perseverative responses and errors on the second run of the WCST, p<.05. further controlling for the effect of dependence severity patients in early methadone withdrawal made selectively more perseverative responses and errors than did recently dosed p with no difference on nonperseverative errors. findings were consistent hypothesis that opioid like alcoholism cocaine addiction is associated disruption executive cognitive functions mediated by prefrontal cortex. abstract.> |
