A Light in the Darkness: Repetitive Transcranial Magnetic Stimulation (rTMS) to Treat the Hedonic Dysregulation of Addiction.

: The present paper discusses the potential use of repetitive transcranial magnetic stimulation (rTMS) for the treatment of addiction, within a conceptual framework that includes the "dark side" of addiction. New findings suggest that rTMS may rescue specific reward system dysfunction that underlies the pathophysiology of addiction by exposing widely under-recognized and untreated key clinical and psychopathological aspects of addictive disorders. Our paper sheds light on the relevance of these hidden dimensions for the development of effective treatment interventions. In particular, we argue that rTMS may have an impact on craving by reversing the allostatic load of hedonic dysregulation.
