Trail making requires cognitive flexibility generated through the dorsolateral and medial prefrontal cortices. The present study investigated practice effects during repeated administrations of verbal and nonverbal memory tests which have the same administration format.At the end of the second trial, inform the subject that (s)he will be asked to recall these words again by saying, “ I will ask you to recall those words again at the end of the test.” Association between MoCA and UPDRS (Odds Ratio 1.07 (95 CI 1.021.11) p 0.006 was determined to be due to the motor items of the MoCA. Try to remember and tell me as many words as you can, including words you said the first time.” Put a check in the allocated space for each word the subject recalls after the second trial. Despite normal MMSE scores (> 25), 52 scored positive for cognitive impairment on MoCA (< 26) indicating greater potential sensitivity of MoCA. When the subject indicates that (s)he has finished (has recalled all words), or can recall no more words, read the list a second time with the following instructions: “ I am going to read the same list for a second time. It doesn’t matter in what order you say them.” Mark a check in the allocated space for each word the subject produces on this first trial. With its widespread clinical use, a significant issue inherent in cognitive assessment is the gain of test scores due to an increased familiarity of test stimuli and procedure as a result of repeated exposures to the same test, a phenomenon known as the practice effect. When I am through, tell me as many words as you can remember. I am going to read a list of words that you will have to remember now and later on. Read a list of 5 words at a rate of 1 word per second, giving the following instructions: “ This is a memory test. Studies in healthy older adults gained contrasting evidence: in some studies, MoCA performances remained relatively stable over time 8, 9, while in others an increase in MoCA scores suggested the influence of a test-retest practice effect, particularly for relatively short time intervals between the evaluations 10, 11.
