age difference, the findings may still be valid as there were no systematic correlations across age and the top significant variables. However, we do acknowledge that age matching across the groups may be crucial as functional connectivity changes due to a neuropsychiatric condition, as in the case of autism spectrum disorders, may show opposing patterns during different developmental stages [127]. Alternatively, future studies may consider adding demographic factors (i.e., age, gender, race, education, etc.) in the classification model in order to determine the predictive significance of these factors. Second, the sample of the current study contained only males and therefore the generalizability of the findings may be limited. It is suggested that future studies use both age- and gender-matched groups. Third, the influence of a family history of AUD was not considered in the current study, and future studies may additionally examine family history information in order to explore whether the aberrations in FC are due to chronic alcohol consumption or preexisting neural endophenotypic features. Fourth, the range of neuropsychological testing was limited to only two tests, and would be strengthened by future studies that administered a comprehensive battery of neuropsychological tests to elucidate specific patterns of deficits and their
