“…Although sleep-related complaints and electroencephalographic changes are generally encountered in psychiatric disorders, sleep complaints, such as insomnia, hypersomnia and nightmares, are more common in suicidal patients (Agargun and Cartwright, 2003;Bernert et al, 2005). Dream variables collected during rapid eye movement (REM) interruptions and REM sleep abnormalities have also been related to suicidal tendencies in depressed patients (Agargun et al, 1998;Agargun and Cartwright, 2003), as well and the frequency of nightmares has been directly related to suicide risk (Tankensen et al, 2001). Sleep studies have reported various polysomnographic findings including increased REM time and activity in suicidal patients with depression.…”

An intrinsic association between suicidal ideation and sleep disorders in patients with depressive disorder has been observed in recent studies. This study was conducted in order to examine the relationship between suicidal ideation and sleep disorders, such as insomnia and excessive sleepiness, in outpatients with major depressive disorder. Seventy patients with diagnoses of major depressive disorder were interviewed and assessed with the Sleep Habits Questionnaire and the Beck Scale for Suicidal Ideation (SSI). Data analyses were performed through descriptive analysis, Students t-test, Chi-square test and logistic regression model, with a statistical significance of 5%. In this study, depressed patients had high SSI scores (6.12 ± 2.67), particularly for active suicidal ideation (1.61 ± 0.39) and specific plans for suicide components (1.51 ± 0.40). Depressed patients with insomnia had significantly higher SSI scores (7.39 ± 2.84), in relation to patients with excessive sleepiness (3.68 ± 1.73). Furthermore it was observed that insomniac patients had significantly higher scores on the following components: active suicide ideation, specific plans for suicide and previous suicide attempts. The results of multivariate analysis showed that only insomnia had a significant association with suicidal ideation. Thus, sleep disturbances, particularly insomnia, should be considered in the assessment of suicidal risk in outpatients with depressive disorder.

“…As we have mentioned above, frequent nightmares have been noted to be related to suicidality in depressed patients, particularly among women (Ağargün et al, 1998). A prospective follow-up study in a sample drawn from the general population also reported that the frequency of nightmares is directly related to the risk of suicide ( The 176 outpatients completed measures on sleep disturbances, suicidal symptoms.…”

“…Several recent studies have examined the association between sleep disturbance and suicide rates in patients with a range of psychiatric disorders, including major depression, panic disorder, and schizophrenia (Agargun et al, 1998a;Agargun and Kara, 1998b;Singareddy and Balon, 2001). Wojnar et al (2009) conducted the first study examining the association between symptoms of insomnia and suicidal behavior over a 12-month period.…”

“…So far, the role of sleep on suicide has often been discussed in terms of symptoms of depression (Agargun et al, 1998a;Agargun and Kara, 1998b;Singareddy and Balon, 2001); however, it has been suggested that maintenance of sleep is involved in suicidal behavior independent of depression (Turvey et al, 2002;Fujino et al, 2005;Bernert and Joiner, 2007). Potential links among these factors are illustrated in Fig.…”

This article reviews evidence supporting the hypothesis that suicide rates in Japan could be reduced by elevating serotonin levels via increasing the average duration of sleep. Seven major relevant findings were apparent in the literature: 1) Sleep loss is associated with suicide, but the direction of causality is equivocal. 2) Decreased serotonergic activity may be involved in suicidal behavior. 3) Sleep debt may decrease serotonergic activity. 4) The suicide rate in Japan has remained at a heightened level for the past 12 years. 5) The average sleep duration in Japan has decreased over the past 40 years. 6) The average sleep duration in Japan is among the lowest in the world. 7) The average sleep duration in Japan plateaued in 1995 and has been relatively stable since. From the research reviewed, two major problematic issues were apparent: 1) Most people in Japan receive inadequate sleep. 2) Individuals whose sleep is inadequate are unlikely to be sufficiently physically active to stimulate serotonergic systems to a desirable level. I propose that public health initiatives encouraging a longer duration of sleep may provide a relatively simple way of addressing the disturbing current trend in Japan. The combination of actigraph and brain serotonin level measurement could allow large population-based cohort studies to be designed, to elucidate the causal links between sleep duration, serotonin levels, and suicide rates.
