The repetitive excessive use of internet has led to an increasing number of reports about the negative consequences of overuse and is now viewed as an important public health issue, although the diagnosis of internet addiction remains problematic. Increasing knowledge about the neurobiological mechanism of behavioral addictions will promote future research and is essential for the development of specific and effective treatment.
The relationship between substance use disorders (SUD) and brain deficits has been studied extensively. However, there is still a lack of research focusing on the structural neural connectivity in long-term polydrug use disorder (PUD). Since a deficiency in white matter integrity has been reported as being related to various parameters of increased psychopathology, it might be considered an aggravating factor in the treatment of SUD.
We investigated the relationship between creativity, personality, latent inhibition (LI), and psychopathology. For this purpose, a sample of actors, 2 clinical samples (alcohol and polydrug dependents), and a group of university students were compared with respect to psychometrically determined creativity, personality, and LI. The results suggest that actors and polydrug dependents can be characterized by (a) high scores in the personality dimension psychoticism, (b) high originality during creative idea generation, and (c) decreased LI as compared with the other groups.
