ANCOVA showed a highly significant difference between groups for the ACE-R total (F = 233.9, p < 0.01), subdomains [orientation/attention (F = 131.2, p < 0.01), memory (F = 390.9, p < 0.01), verbal fluency (F = 103.5, p < 0.01), language (F = 62.7, p < 0.01) and visuospatial (F = 61.0, p < 0.01)] and MMSE (ACE-R) (F = 170.6, p < 0.01).
