speed. Balance was measured by requiring participants to stand on one foot, and response speed was measured when participants turned a knurled post between the thumb and forefinger, and when participants performed the Digit Symbol subtest of the Wechsler Adult Intelligence Scale. Alcoholics had poorer balance, and they were slower on the speed tests. Poorer performance on all tests correlated with DTI measures of regional white matter degradation in frontal and occipital forceps, internal and external capsules, fornix, and inferior cingulate bundle.
