“…In addition, when patient is not under treatment during euthymic state, a suicide risk is even higher (Gibbons et al, 2009). Previous studies revealed a link between general sleep disturbances and suicidal ideation, as well as other suicide related behaviors in BD patients during the state of euthymia (Rocha et al, 2016). Furthermore, Malloy-Diniz et al (2011) showed that BD patients during euthymic state are more impulsive than healthy controls (HCs) while Parmentier et al (2012) found out that these patients may experience indirect hostility and irritability associated with suicidal behaviors.…”

Objective The occurrence of death by suicide in patients diagnosed with bipolar disorder is as much as 60 times greater than in the general population. Even during the state of euthymia patients are characterized by suicide risk. The aim of the study is to investigate the baseline brain activity in euthymic bipolar disorder patients in regard to suicide risk. We hypothesized that patients compared to healthy control group will demonstrate altered functional connectivity among resting state networks which will be directly related to current suicide risk. Method 41 subjects were enrolled in the study consisting control group ( n = 21) and euthymic bipolar disorder patients group ( n = 20). Functional magnetic resonance imaging was used to evaluate resting state brain activity and ROI–ROI functional connectivity analysis was performed. Suicidal risk was estimated using The Suicide Behaviors Questionnaire-Revised. Results A two sample t -test revealed decreased functional connectivity between regions involved in the salience network in patients compared to the control group. This decrease was negatively correlated with current suicide risk. Conclusion Obtained results suggest the association between risk of suicide and activity of regions responsible for functions such as learning from mistakes, prospective thinking, and sensory integration.

Very few studies have been conducted on sleep quality during the euthymic phase of bipolar disorders. Also, very little is known about the correlates and predictors of sleep quality during this period. 16 The majority of such existing studies have been carried out in non-Caucasian populations. This is concerning since racial/ethnic disparities exist for sleep quality. Furthermore, there is evidence to suggest that sleep quality amongst racial/ethnic minorities is disproportionately understudied. 17 Background: Bipolar disorder is highly under-researched in Africa. Existing studies show that racial/ethnic disparities exist for sleep quality. Poor sleep quality in bipolar disorder causes significant morbidity and mortality even during periods of euthymia. Aim: This study aimed to assess sleep quality and its correlates amongst euthymic patients with bipolar I disorder from Nigeria. Setting: The study was carried out in a teaching hospital, and state hospital, in Ibadan, Nigeria. Method: This cross-sectional study was conducted amongst 76 euthymic bipolar patients aged between 18 and 60 years, meeting the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) diagnostic criteria for bipolar disorder. Euthymia was defined as having a score of ≤ 5 on the Young Mania Rating Scale and < 8 on the Hamilton Depression Rating Scale. Sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI).Results: A total of 37 (48.7%) participants had poor quality sleep. Sleep quality was associated with marital status (p = 0.013) and suicide plan (p = 0.047). Participants with good sleep quality had higher total sleep duration, lower time to fall asleep (sleep latency), better subjective quality of sleep, were less likely to use sleep medications and had less daytime dysfunction than participants with poor sleep quality. All p-values were < 0.05. Subjective quality of sleep, ongoing use of sleep medication, daytime dysfunction were independently associated with poor sleep quality. Conclusion:Poor sleep quality frequently persists during euthymic periods in patients with bipolar disorder. The correlates identified can be targeted for intervention during treatment.

Se realizó una revisión sistemática de la literatura con el objetivo de determinar si los trastornos del ciclo sueño-vigilia pueden ser considerados marcadores de ideación suicida. Para llevar a cabo la revisión y responder la pregunta de investigación fue llevada a cabo una búsqueda en las bases de datos bibliográficos del área de la salud: Medline, Scielo y LILACS durante los meses de mayo a diciembre de 2020. Se incluyeron estudios originales cuantitativos y revisiones cualitativas, así como meta-análisis, publicados en los últimos 10 años en idiomas español, inglés y portugués. Fueron encontrados 39 artículos que cumplieron con los criterios de inclusión, de los cuales 37 estaban escritos en idioma inglés y 2 en idioma portugués. La base de datos Medline aportó el 79,4 % de los artículos utilizados. El 87, 1 % de los artículos se corresponden con estudios originales cuantitativos. La presenta revisión sistemática evidenció que los trastornos del sueño son un factor de riesgo independiente en relación con la conducta suicida en diferentes contextos clínicos y entornos socio-culturales.
