Abstract

Drug addiction has been linked to impairments in three broad functional domains: 1) approach-related behavior, 2) negative emotionality, and 3) executive function. In our previous work, we described the existence of three distinct neurobehavioral subtypes in those with past substance use disorder (SUD), each separately impaired on one of these three domains. Here, we investigated whether similar subtypes exist in a separate sample of participants with current cocaine use disorder (CUD).
