ABSTRACT
Objective To explore the impairment of time perception in patients with Parkinson's disease (PD).Method Thirty-two individuals with idiopathic PD were compared with 32 matched healthy controls using a time reproduction task.Result Compared with healthy controls for the 3-second duration reproduction task, PD patients in the setting of a delay by 1 s ( (2.78 ±0.31 ) s and (2.15 ±0.34) s,respectively) and a delay by 5 s ( (2.74 ±0.32) s and (2.08 ±0.37) s, respectively) showed impairment in time perception with a significant under-estimation of the duration ( t = - 7.459, - 7.533, both P <0.01 ).When compared with healthy controls for the 5-second duration reproduction task, PD patients in the setting of a delay by 1 s ( (3.99 ±0.39) s and (3.11 ±0.52) s) and 5 s ( (4.05 ±0.40) s and (2.96 ±0.54) s) also showed impairment in time perception with a significant under-estimation of the duration (t =-7.609 and - 9.120, both P < 0.01 ).When compared with healthy controls for the 600-millisecond duration reproduction task, PD patients in the setting of delay by 1 s ((0.91 ±0.18) s and (0.90 ±0.18) s, respectively) and by 5 s ( (0.89 ± 0.16) s and (0.91 ± 0.17 ) s, respectively) did not have impaired time perception, and the difference was not significant ( t = 0.347, P = 0.730; t = - 0.519, P =0.606, respectively).Conclusion Our data indicates that time perception is impaired in PD patients.Impaired time perception is mainly an under-estimation of the time interval in seconds rather than milliseconds.
