in corpus callosum in heavy drinking older men or abstinent men with AUD compared to same-sex controls but not in women (Kapogiannis et al., 2012; Ruiz et al., 2013). Lastly, three studies found that men with AUD had smaller reward system and cerebellar volume compared to women with AUD (Sawyer et al., 2016; Sullivan, Rohlfing, & Pfefferbaum, 2010); although, SG findings are mixed and likely due to the inclusion of a disproportionate sample of men compared to women (Cardenas, Hough, Durazzo, & Meyerhoff, 2020).
