The Periventricular and Deep WMSH volumes are adjusted for inter-subject differences in total cerebral white matter volume.
Alcohol use measures represent the quantiy of alcohol consumed during a given time frame.
Alcohol dose measures represent the average monthly intake of alcohol during a given time frame.
Family drinking density is the proportion of first-degree relatives who were problem drinkers.
