Fig. 6 shows the differences of component weights from subjects with AUD and control subjects. Left cerebellum, right caudate, left and right overall white matter and 5th ventricle all show significantly, p < 0.05, different weights in the AUD subject’s component compared with the control component. The significantly larger deviations observed in subjects with AUD suggest that the brain volume component extracted from these subjects is not due to normal aging effects.
