Introduction. Many studies show the close relationship between impulsiveness and addictive disorders. Neuropsychology has stressed the influence the misuse of cocaine has on executive functions, and hence on the decision-taking ability. We propose to compare impulsiveness among groups of active cocaine addicts and those reacting well to the treatment in different moments of their evolution. Materials and methods. A consecutive sample of 85 subjects demanding outpatient treatment for cocaine dependence was selected. To measure impulsiveness the Barratt Impulsiveness Scale (BIS-11) was used, and the IPDE for personality diagnosis. Results. The impulsiveness previous to treatment was independent from the presence of cluster B personality disorders. After a month of evolution there appeared significant differences in nonplanning subescale among group of active cocaine addicts and those who showed some amelioration. After three months, differences were produced on global, cognitive and nonplanning scores. Discussion: The increase on impulsiveness is due, at least in part, to the effect of a continual misuse of cocaine, and it has a certain degree of reversal, that starts to be noticeable after between 4 and 12 weeks. We propose to study in more depth the influence that the continual misuse of cocaine has in the habitual behaviour, as well as the underlying neuropsychological mechanisms.
