ObjectivesStructure of executive function was examined and we contrasted performance of substance dependent individuals (polysubstance users) and control participants on neuropsychological measures assessing the different executive components obtained. Additionally, we contrasted performance of polysubstance users with preference for cocaine vs heroin and controls to explore possible differential effects of the main substance abused on executive impairment.MethodsTwo groups of participants were… 
Impulsivity and executive functions in polysubstance-using rave attenders
Rave attenders have selective alterations of impulsive personality and executive functions that can contribute to delineate the neuropsychological profiles that distinguish recreational polysubstance use from substance dependence.
Neuropsychological consequences of alcohol and drug abuse on different components of executive functions
Findings indicate that alcohol abuse is negatively associated with fluency and decision-making deficits, whereas the different drugs motivating treatment have both generalized and specific deleterious effects on different executive components.
Differential Improvement of Executive Functions During Abstinence in Cocaine-Dependent Patients: A Longitudinal Study
Results suggest that executive improvement and treatment adherence in cocaine abusers in abstinence is related to intrinsic cognitive characteristics of patients.
Neuropsychological profiling of impulsivity and compulsivity in cocaine dependent individuals
CDI has both inhibition and perseveration deficits; both patterns were broadly indicative of orbitofrontal dysfunction in the context of reinforcement learning.
Structural and functional signatures of executive deficits after early use of cocaine depend upon the route of administration
C cocaine routes of administration are associated to a differential profile that may not be due direct effects of stimulant action but also driven by cognitive and biological differences in key executive functioning and attention areas, which could inform clinical management and should be taken into account in clinical research.
Normal Decision-Making and Executive Functions in Alcohol Dependent Individuals
The results suggest that the sample of pure AD do not have global deficits in decision-making as measured by the IGT and that their poor decisions regarding their alcohol consumption are limited to drinking.


Profile of Executive and Memory Function Associated with Amphetamine and Opiate Dependence
While performance of female drug users was normal, male drug users showed significant impairment compared to both their female counterparts and male controls, and there was no difference in performance between current and former drug users.
Differential effects of cocaine and cocaine alcohol on neurocognitive performance
The concomitant use of cocaine and alcohol may have additive negative effects on the brain as compared to the use of only one of these two substances.
The differential effects of ecstasy/polydrug use on executive components: shifting, inhibition, updating and access to semantic memory
Support is provided for ecstasy/polydrug-related deficits in memory updating and in access to long-term memory and the surplus evident on the inhibition task should be treated with some caution.
Executive functioning early in abstinence from alcohol.
Executive functions are impaired early in abstinence and should be taken into account when early behavioral treatments are being developed, and patients in the alcohol-dependent sample were more likely to perceive themselves as cognitively impaired.
