The influence of premorbid characteristics on neuropsychological performance was examined using bivariate correlations of parental history of SUD with FA and MD and entered into regression analyses if significant (p <.05). FA in the right ILF was positively correlated with parental history of SUD (r = .39, p = .02). Regression analyses indicated that parental history of SUD did not predict neuropsychological performance beyond FA. No significant findings were found between MD and parental history of SUD.
