Participants who met UK Brain Bank diagnosis criteria for Parkinson's disease, with I\u2013III Hoehn &amp; Yahr, aged 50\u201380, and nondemented (Mini\u2010Mental State Examination \u2265 23) were recruited. Patient's cognitive performance and functional and quality\u2010of\u2010life 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\u2010III) into 2 groups: an experimental group and a control group. The experimental group received 4 weeks of 3 weekly 45\u2010minute sessions using multimedia software and paper\u2010and\u2010pencil cognitive exercises, and the control group received speech therapy. A total of 28 patients were analyzed. Compared with the control group participants (n = 12), the experimental group participants (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\u2010reported 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 Parkinson's disease. \u00a9 2011 Movement Disorder
