Values are given as mean and standard deviation; CVLT, California Verbal Learning Test; F%, Percentage of mistakes in relation to edited signs; KL, Total of correct edited signs minus total of wrong edited signs; min, minutes; MOCA, Montreal Cognitive Assessment; n, number; p, level of significance; PD, Parkinson's Disease; PR, percentage range; RWT, Regensburger word fluency test. Bold values represent significant values.
