    Substance use disorder (SUD) is prevalent in SUD (FH+) individuals with a family history (FH) , and this increased risk of SUD is likely to be transmitted through complex genetic and environmental / learning mechanisms .

    Since the risk of SUD is related to anxiety and impulsivity, they also investigated the correlation between these psychological characteristics and volume /SSS .

    The study found
    • The shape of the right anterior hippocampus was markedly inwardly deformed in FH+ adolescents compared with FH- adolescents , whereas the volume of this structure did not differ between groups .

      Zhishun Wang's research proves FH+ Zhishun Wang's research demonstrates that introversion of the adolescent right anterior hippocampus may be associated with an increased risk of SUD due to behavioral dysregulation in FH+ offspring .
