조증 환자의 시간 지각 : 급성기와 관해기 비교 = Time Perception of Bipolar Manic Patients : Comparison between Acute State and Euthymic State

다국어 초록 (Multilingual Abstract)

Objectives : We investigated the time perception of bipolar manic patients in acute state and euthymic state to examine the difference of time perception between two states. And we investigated whether there would be significant correlation between the time perception in acute state and the severity of manic symptoms. Methods : 15 bipolar manic patients were participated. Time reproduction tasks were performed to measure time perception in acute manic state and euthymic state. Participants were asked to observe stimulus presented on a computer screen for a certain length of time, and subsequently asked to reproduce the stimulus for a same length of time by pressing the space bar. Stimuli were presented for 1, 11, 36 seconds. The severity of mood symptoms was assessed with Young Mania Rating Scale (YMRS). Results : On average, time reproductions for 1 second, 11 seconds in acute manic state were significantly shorter than those in euthymic state (p values : 0.02, ＜.001, ＜.001 for each). And time reproductions in acute manic state were correlated with the YMRS score. Conclusion : Reproducing time stimuli shorter in manic state than in euthymic state suggests that bipolar patients in manic state perceive flow of time faster than in euthymic state. The results also suggest that the severity of manic symptoms is correlated with time perception.
