To correct for multiple comparisons, the threshold for a significant correlation was adjusted to the level of p = 0.0045 according to the Bonferroni method)

Digit Symbol Test = Digit Symbol subtest of the German version of the Wechsler Adult Intelligence Scale; Mosaic test = Mosaic subtest of the German version of the Wechsler Adult Intelligence Scale; Digit Span = Digit Span subtest of the German version of the Wechsler Adult Intelligence Scale; Benton Test = correct answers of the Benton Visual Retention Test (revised form); Verbal Fluency = Sum score verbal fluency (semantic and phonemic) of the German version of the CERAD-NP-Plus test battery; Word List Learning = Subtest Word List-Learning of the German version of the CERAD-NP-Plus test battery; Word List Delayed Recall = Subtest Word List-Delayed Recall of the German version of the CERAD-NP-Plus test battery; Word List Recognition = Subtest Word List-Recognition of the German version of the CERAD-NP-Plus test battery; Figure Recall = Subtest Figure Recall of the German version of the CERAD-NP-Plus test battery; TMT-A = Trail Making Test - Version A; TMT-B = Trail Making Test - Version B
