Rationale: Studies of time perception in Temporal lobe epilepsy (TLE) are not well established and the duration of a single event was mainly evaluated rather than the time interval between a series of events [1,2,3]. We intend to promote the understanding of time perception in TLE patients by evaluating time perception and temporal order memory according to the presented time interval.
Methods: Fifteen normal and fifteen TLE patients underwent the time perception task and temporal order memory task. The mean age of 15 heathy adult controls was 56.6 ± 7.2 years, and the mean age of 15 TLE patients was 54.1 ± 12.4 years and the difference was not statistically significant. The time perception task and temporal order memory task were performed using monitor screen of laptop and the participants responded with keyboard. A detailed paradigm description is given in the figure below
Results: There were no significant differences between normal controls and TLE patients on the time perception task (85% in controls vs. 87% in TLE) [Table]. There were no significant differences between normal controls and TLE patients on the temporal order memory task (56% in controls vs. 57% in TLE) [Table]. However, the correlation between time perception and temporal order memory showed different between normal controls and TLE patients. In controls, there was a significant correlation between the performances of 70-ms trials of the time perception task and the total temporal order memory task (r= 0.54, P< 0.05), long time interval trials (r=0.62, P< 0.05) and time lag 6 trials (r=0.61, P< 0.05). There was a significant negative correlation between the performance of time lag 6 trials of temporal order memory task and the simultaneous stimulus trials of time perception task (r= - 0.54, P< 0.05). In TLE patients, the correlation coefficient that was significant in the control group was not statistically significant. However, a significant correlation was observed only in the 600ms trials of time perception task and the time lag 2 trials of temporal order memory task.
