Theory of Mind in Substance Users: A Systematic Minireview.
Theory of mind concerns the sociocognitive ability to infer others' thoughts. It has been theorized to be impaired in substance use and abuse, as its alterations might explain negative social and interpersonal outcomes noted in the course of disorders. In addition, the brain structures involved in Theory of Mind (ToM) have been found to be disrupted in drug use conditions.



We undertook a systematic review of ToM functioning in drug use conditions.



Four electronic databases (MEDLINE, Web of Science, PsycINFO, and Embase) were searched to find studies that have addressed ToM and conditions related to actual or previous drug use.



The search found 147 papers, of which 14 fulfilled our review eligibility criteria. Different methods were used, but overall, results indicated that drugs are related to ToM deficits, particularly related to alcohol and amphetamines use. These impairments correlate with other clinical and cognitive functions.



Despite the lack of studies and the methodological limitations of the existing ones Theory of Mind seems to play a role in drug use conditions, which requires further investigation.
