al., 2013, Zahr and Pfefferbaum, 2017, Zorlu et al., 2014), suggesting their role in cognitive impairments. However, few studies have investigated the relationship of volumetric and/or diffusion characteristics with performance on neuropsychological tests (e.g., Chanraud et al., 2009, Schulte et al., 2012). Combining multimodal assessments such as volumetric and diffusion characteristics can further the understanding of their relationship with performance on neuropsychological tests to accurately characterize structural and functional abnormalities in AUD.
