The aim of this study was to analyze the efficacy of a cognitive training program on cognitive performance and quality of life in nondemented @entity191 @entity1 . @entity1 who met UK Brain Bank diagnosis criteria for @entity191 , with I-III Hoehn _ Yahr, aged 50-80, and nondemented (Mini-Mental State Examination >=  23) were recruited. @entity1 's cognitive performance and functional and quality-of-life measures were assessed with standardized neuropsychological tests and scales at baseline and after 4 weeks. Subjects were randomly and blindly allocated by age and premorbid intelligence (Vocabulary, Wechsler Adult Intelligence Scale-III) into 2 groups: an experimental group and a control group. The experimental group received 4 weeks of 3 weekly 45-minute sessions using multimedia software and paper-and-pencil cognitive exercises, and the control group received speech therapy. A total of 28 @entity1 were analyzed. Compared with the control group @entity1 (n = 12), the experimental group @entity1 (n = 16) demonstrated improved performance in tests of attention, information processing speed, memory, visuospatial and visuoconstructive abilities, semantic verbal fluency, and executive functions. There were no observable benefits in self-reported quality of life or cognitive difficulties in activities of daily living. We concluded that intensive cognitive training may be a useful tool in the management of cognitive functions in @entity191 .    2011 @entity717 Society.
