Line bisection test in Parkinson Disease

Parkinson's disease (PD) is a neurodegenerative disorder that is involved in the decline of many cognitive functions, including visuospatial perception. Visual-spatial deficits involve personal/peripersonal space and the functions of visual analysis, attention or spatial orientation. Systematic monitoring using specific tests for visuospatial functions can be useful to improve the daily life of patients who deal not only with motor but also with perceptual issues. In the present study, we used the line bisection test (motor involvement) and the evaluation of already bisected lines (visual assessment in the absence of motor involvement), both on paper and on computer, in patients and sex/age matched controls. No differences were found between the groups in the distance from the center (absolute value) in the bisection test. Also, there were no differences in the number of correct and incorrect answers in the evaluation test. Differences were found between groups in the time-measured line bisection test on the computer, with patients needing more time to move the line to the center and press the appropriate key to move on to the next line. Also, in the computer judgement (condition without motor involvement in peripersonal space) difference was observed in both patients with right-sided symptoms (RLD) and left-sided symptoms (LPD) who evaluated the position of cursor in the right and left side of the line, respectively. Time measurement of all administered tasks is suggested for future research in patients of different stages of PD.
