“…Our results extend prior research on compromised error awareness/processing 6,18,86 and gray matter abnormalities 43,44,66 in drug addiction, offering the intriguing suggestion that impaired insight may drive such effects. Our results also raise the possibility that a specific CUD subgroup (iCUD) might benefit from therapeutic interventions directed at enhancing the neuropsychological mechanisms underlying insight/self-awareness 1 [e.g., self-relevant (tailored) motivational interventions 87,88 ]. More broadly, our results can inform other neuropsychiatric disorders (e.g., anosognosia, alexithymia, schizophrenia, mania) 89 , similarly characterized by impaired insight and disadvantageous, unwanted, or inappropriate behaviors (e.g., leading to violence, self-harm).…”
