abstract="AIM: To explore the relation between suicidal behavior and sleep electroencephalographic (EEG) parameters in depressive patients. <br><br>METHODS: It was estimated for sleep EEG in 6 depressive patients with suicidal behavior, 12 depressive patients without suicidal behavior and 10 normal controls. The states of sleeping processes, sleeping structure and fast wave sleep were observed. <br><br>RESULTS: 1 Time from awake to get up was significantly longer in the depressive patients with suicidal behavior (13.3 ± 6.4) than the normal control subjects (3.1 ± 2.8) (t = 4.45, P < 0.05), whereas it was not significantly different between depressive patients without suicidal behavior and the normal controls (P > 0.05 ); 2 The percent of slow wave sleep 1 stage was significantly higher in depressive patients without suicidal behavior [(6.5 ± 8.6)%] than the depressive patients with suicidal behavior [(8.4 ± 1.7)%] and the normal control subjects [(10.0 ± 1.9)%] (t = 2.25, 2.33, P < 0.05), whereas there was no significant difference between the depressive patients with suicidal behavior and the normal control subjects (P > 0.05). <br><br>CONCLUSION: 1 Overtime from awake to get up is a biologic marker of susceptible suicidal behavior in depressive patients. 2 It was usually increased for slow wave sleep 1 stage percent in depressive patients. If depression is very severe, the slow wave sleep 1 stage percent will be normalized, whereas the latter could be used to predict suicide risk.<p /><p>Language: zh</p>",
