Abstract
- The purpose of this study is to examine frontal lobe function of non-dementia Parkinson's disease (PD) patients. We examined the neuropsychological and behavioral evaluation (Stroop reaction time: SRT). Target image (20%) and non-target image (80%) were presented to PD patients, healthy elderly controls, and healthy young subjects at random. We instructed subjects that the button should pressed on the target image. This study was designed to investigate the mental set under three conditions. The Stroop test, Word Fluency Test (WFT), and Geriatric Depression Scale (GDS) were used to assess cognitive function. The SRT of PD were congruent condition and incongruent condition increased compared with simple condition. The delay of a similar SRT was seen in the healthy elderly control and young groups. However, the SRT of PD patients was slower under incongruent condition than under congruent condition. It appears that PD spent time on judgment in under incongruent condition because the meaning of the character did not correspond to the color of the character. Because, there were no significant between PD and healthy elderly subjects in Stroop test, WFT, and GDS, frontal lobe function had a partial deficit. The SRT of PD was increased by the partial deficit in information processing ability in addition to movement dysfunction.
