  • CSB patients showed significantly more impulsivity on a behavioral task.
  • fMRI brain scans show that individuals who meet the diagnostic criteria for compulsive sexual behavior had significantly higher superior frontal region mean diffusivity (MD) than controls.
In recent years there has been increased attention in a clinical syndrome characterized by excessive sexual thoughts, sexual urges, and/or sexual behaviors that has many aspects in common with impulse control disorders. This study provides a preliminary examination of the impulsive aspects of this syndrome, Compulsive Sexual Behavior (CSB), as conceptualized by Coleman and colleagues. Sixteen male subjects, 8 CSB patients and 8 non-patient controls, completed psychometric measures of impulsivity and compulsive sexual behavior,... READ FULL ABSTRACT
  • "The data presented in this paper are consistent with the assumption that CSB has much in common with impulse control disorders, such as kleptomania, compulsive gambling, and eating disorders. Specifically, we found that individuals who meet diagnostic criteria for compulsive sexual behavior score higher on self report measures of impulsivity, including measures of overall impulsivity and the personality factor, Constraint."
