The well-known neuropsychological Rey Osterrieth Complex Figure Test (ROCF) was used to analyze the patients’ visual memory and visual constructive capacity33 and included 3 subtests. Initially, the subjects were asked to copy a geometrical figure that was shown to them. This first subtest was not assessed in the present study. In the next 2, subtests, which were analyzed in this study, the subjects were asked to draw a geometrical figure shown to them before, both immediately (ROCF copy) and after a 30-min delay (ROCF delay).
The Trail-Making-Test B (TMT-B) was similar to the TMT-A; however, the patients were asked to connect letters and numbers in alternation (eg, 1-A-2-B)31. The time needed for correct connection was measured in seconds.
