Subcortical volumes are reduced in short-term and long-term abstinent alcoholics but not those with a comorbid stimulant disorder.

NSAC: Comparing NSAC and STAA DAO, the multivariate test was highly significant (Wilks' λ 7,100 = 0.79, p < .001), with smaller volumes in STAA DAO for the accumbens (F 1,106 = 8.95, p < .003, es = 7.8), hippocampus (F 1,106 = 16.58, p = .001, es = 13.5), and pallidum (F 1,106 = 9.10, P = .003, es = 7.0), and slightly larger volumes for the thalamus(F 1,106 = 3.94, p = .05, es = 3.6).

NSAC: Comparing NSAC and LTAA DAO, the multivariate test was marginally significant (Wilks' λ 7,111 = 0.887, p = .059), with smaller volumes in LTAA DAO for the accumbens (F 1,117 = 4.17. p = .043, es = 3.4), hippocampus (F 1,117 = 6.41, p = .013, es = 5.2), pallidum (F 1,117 = 5.08, p = .026, es = 4.2), putamen (F 1,117 = 4.92, p = .028, es = 4.0),and thalamus(F 1,117 = 4.90, p = .029, es = 4.06).
