 The bradyphrenia in Parkinson's disease disfunctions information-processing impedes the occupational performance. Using a visual search task, we examined the characteristics of impaired visual information-processing, in both preattentive processes and focal attentional processes, in 17 patients suffering from Parkinson's disease without dementia. Results indicated that the preattentive processes in patients with Parkinson's disease functions at the same level as in healthy subjects, but the focal attentional process was impaired. We suggested that patients with Parkinson's disease had defects in visual selective attention. These findings could benefits from cognitive occupational therapy for bradyphrenia.
