Adverse Childhood Life Events and Postpartum Mood Episodes in Bipolar Disorder
Background:
The early postpartum has been established as a period of increased vulnerability for psychiatric mood illness. Women with bipolar disorder (BD) in particular are at elevated risk of postnatal depression (PND) and of postpartum psychosis (PP). Though adverse childhood life events (ACLEs) have been implicated in the aetiology of PND, this has rarely been studied in relation to PP. Furthermore, despite being at high risk of relapse following childbirth, little research has assessed the relationship between ACLEs and postnatal mood episodes (PNEs) exclusively in women with BD. Therefore, our aim was to explore associations between ACLEs and occurrence of both PND and PP in a large sample of women with BD.
Methods:
Participants were 665 parous women with BD who had been recruited into the Bipolar Disorder Research Network study. Diagnoses and lifetime psychopathology were obtained via a semi-structured interview (SCAN). Postnatal psychiatric history and experience of 7 ACLEs were also assessed. Where available, all information obtained at interview was confirmed from psychiatric case notes. Women were classified into three groups according to postnatal psychiatric history: 1) those who had experienced no postnatal mood episode (no PNE, n=224), 2) women with a history of PND (n=223) and 3) women who had experienced PP (n=208). A Pearsonâs chi-square test was used to compare the prevalence of each type of ACLE between women in the no PNE group and those with a history of PND or PP.
Results:
Women with PND were significantly more likely to have experienced emotional, sexual or physical abuse in childhood compared with women who had no history of a PNE (p<0.05). In particular, childhood sexual abuse was reported significantly more in the PND than the no PNE group (P<0.05). In contrast, there were no significant differences in the frequency of reporting of any ACLEs between women who had no PNE and those with PP.
Conclusions:
Our findings indicate that childhood abuse, sexual abuse in particular, is associated with PND among women with BD. In contrast, we found no evidence for an association between any ACLE and PP, suggesting that biological factors are likely to play a more important role in the aetiology of psychosis in the early postpartum
Agitated Depression in Bipolar Disorder
Objectives
It has been suggested that agitated depression (AD) is a common, severe feature in bipolar disorder. We aimed to estimate the prevalence of AD and investigate whether presence of AD was associated with episodic and lifetime clinical features in a large wellâcharacterised bipolar disorder sample.
Method
The prevalence of agitation, based on semiâstructured interview and medical caseânotes, in the most severe depressive episode was estimated in 2925 individuals with DSMâIV bipolar disorder recruited into the UK Bipolar Disorder Research Network. Predictors of agitation were ascertained using symptoms within the same episode and lifetime clinical features using multivariate models.
Results
32.3% (n=946) experienced agitation during the worst depressive episode. Within the same episode, significant predictors of presence of agitation were: insomnia (OR 2.119, p<.001), poor concentration (OR 1.966, p=.027), decreased libido (OR 1.960, p<.001), suicidal ideation (OR 1.861, p<.001), slowed activity (OR 1.504, p=.001), and poor appetite (OR 1.297, p=.029). Over the lifetime illness course, coâmorbid panic disorder (OR 2.000, p<.001), suicide attempt (OR 1.399, p=.007), and dysphoric mania (OR 1.354, p=.017) were significantly associated with AD.
Conclusions
Agitation accompanied bipolar depression in at least oneâthird of cases in our sample and was associated with concurrent somatic depressive symptoms, which are also common features of mixed manic states. Furthermore, AD in our sample was associated with lifetime experience of mixed mania, in addition to severe lifetime illness course including comorbid panic disorder and suicidal behaviour. Our results have implications for the diagnosis and treatment of agitated features in bipolar depression
Stratification of the Risk of Bipolar Disorder Recurrences in Pregnancy and Postpartum
Background
Pregnancy and childbirth are a period of high risk for women with bipolar disorder and involve difficult decisions particularly about continuing or stopping medications.
Aims
To explore what clinical predictors may help to individualise the risk of perinatal recurrence in women with bipolar disorder.
Method
Information was gathered retrospectively by semi-structured interview, questionnaires and case-note review from 887 women with bipolar disorder who have had children. Clinical predictors were selected using backwards stepwise logistic regression, conditional permutation random forests and reinforcement
learning trees.
Results
Previous perinatal history of affective psychosis or depression was the most significant predictor of a perinatal recurrence (odds ratio (OR) = 8.5, 95% CI 5.04â14.82 and OR = 3.6, 95% CI 2.55â5.07 respectively) but even parous women with bipolar disorder without a previous perinatal mood episode were at risk
following a subsequent pregnancy, with 7% developing postpartum psychosis.
Conclusions
Previous perinatal history of affective psychosis or depression is the most important predictor of perinatal recurrence in women with bipola
Migraine associated with early onset postpartum depression in women with major depressive disorder
Major depressive disorder (MDD) and migraine are both more common among women than men. Womenâs reproductive years are associated with increased susceptibility to recurrence of both conditions, suggesting a potential role of sex hormonesin aetiology. We examined associations between comorbid migraine and clinical features of MDD in women, including relationships with lifetime reproductive events such as childbirth. Lifetime clinical characteristics and reproductive events in a well-characterised sample of 222 UK women with recurrent MDD, with (n = 98) and without (n = 124) migraine were compared. Women had all been recruited as part of a UK-based ongoing programme of research into the genetic and nongenetic determinants of mood disorders. Multivariate analysis showed a specific association between the lifetime presence of migraine and postpartum depression (PPD) within 6 weeks of delivery (OR = 2.555; 95% CI: 1.037â6.295, p = 0.041). This association did not extend to a broader definition of PPD with onset up to 6 months postpartum. All other factors included in the analysis were not significantly associated with the presence of migraine: family history of depression, younger age at depression onset, history of suicide attempt and severe premenstrual syndrome symptoms. The finding that women with MDD and comorbid migraine may be particularly sensitive to hormonal changes early in the postpartum period leads to aetiological hypotheses and suggests this group may be useful for future studies attempting to characterise PPD and MDD phenotypes. The refinement of such phenotypes has implications for individualising risk and treatment and for future biological
and genetic studies
Commentary: Neural correlates of expected risks and returns in risky choice across development
âWisdom comes with ageâ is an oft-heard expression. It suggests that across development we improve in our ability to make decisionsâbut evidence for its validity is equivocal. In real-world decision-making, there is an adolescent-specific increased propensity to engage in behaviors associated with morbidity and mortality (e.g., road traffic accidents, unprotected sex, violence, drug, and alcohol abuse; Blum and Nelson-Mmari, 2004). However, this inverted u-shape developmental trajectory for risk-taking is typically not observed in laboratory-based studies (Defoe et al., 2015). As such, there exists a need to: (a) bridge the gap between laboratory and real world behavior; and (b) clarify the processes underlying developmental differences in decision-making to inform interventions that target a reduction in health-risking adolescent activities
Adverse childhood experiences and postpartum depression in bipolar disorder
Background Women are particularly vulnerable to recurrence of bipolar disorder (BD) following childbirth. Risk of postpartum psychosis (PP) is especially high, but postpartum depression (PPD) is also common. Adverse childhood experiences (ACEs) have not been associated with PP, but have been associated with PPD in non-bipolar samples. The relationship between ACEs and PPD within BD remains to be investigated. Here, we examined this association in a large, well-defined sample of women with BD. Methods Participants were 575 parous women with DSM-IV BD. Lifetime psychopathology, including perinatal, was assessed via semi-structured interview and case-notes. ACEs, assessed via self-report and case-notes, were compared between women with lifetime PPD (n=368) and those without a lifetime history of perinatal mood episodes (n=207). Results In univariate analysis exposure to 3 or more ACEs, and to childhood abuse specifically, was significantly associated with PPD (p=0.026 and 0.041 respectively), but this did not remain significant after adjusting for lifetime number of episodes of depression and parity. Post-hoc analysis revealed more frequent episodes of depression to be associated with both a history of 3 or more ACEs and of childhood abuse. Limitations Limited range of ACEs assessed and potential recall bias. Conclusions Increased frequency of ACEs and particularly childhood abuse was associated with more frequent lifetime episodes of depression, but not specifically episodes with postpartum onset. Understanding factors that media
Perinatal sleep disruption and postpartum psychosis in bipolar disorder: Findings from the UK BDRN Pregnancy Study
Background
Women with bipolar disorder (BD) are at high risk of postpartum psychosis (PP). The factors that increase risk of PP among women with BD are not fully understood. Here, we examine whether sleep disruption in the perinatal period (poor sleep quality in late pregnancy and sleep deprivation related to childbirth) is associated with PP in a longitudinal study of pregnant women with BD.
Methods
Participants were 76 pregnant women with lifetime DSM-5 bipolar I disorder or schizoaffective-BD, followed from week 12 of pregnancy to 12 weeks postpartum. Demographics and lifetime psychopathology were assessed at baseline via semi-structured interview (Schedules for Clinical Assessment in Neuropsychiatry). Psychopathology and sleep disruption within the current perinatal period were assessed in the third trimester and at 12 weeks postpartum. Data were supplemented by clinician questionnaires and case-note review.
Results
After controlling for prophylactic use of mood stabilising medication, the loss of at least one complete night of sleep across labour/delivery was associated with five times the odds of experiencing PP compared to no or less than one night of sleep loss across labour/delivery (OR 5.19, 95 % CI 1.45â18.54; p = 0.011). Sleep quality in late pregnancy was not associated with PP, and perinatal sleep disruption was not associated with postpartum depression.
Limitations
Lack of objective measures of sleep factors.
Conclusions
In the context of other aetiological factors, severe sleep loss associated with childbirth/the immediate postpartum may act as a final trigger of PP. These findings could have important clinical implications for risk prediction and prevention of PP
Opportunities to engage in positive activities during the COVID-19 pandemic: Perspectives of individuals with mood disorders
Background: Despite cross-sectional population and clinical studies finding individuals with existing mood disorders being adversely impacted by the COVID-19 pandemic, longitudinal studies have not shown a worsening of
psychiatric symptoms. In response to these findings, we explored opportunities to engage in positive activities
during the pandemic from the perspectives of individuals with mood disorders.
Methods: A bespoke survey, containing closed and open questions, was sent to participants with mood disorders
who were part of the UK Bipolar Disorder Research Network (BDRN). Questions related to experiences of positive
impacts of the pandemic, levels of engagement in positive activities and coping strategies.
Results: Response rate was 46.4 % (N = 1688). 61.9 % reported positive life changes during the pandemic, with
slower pace of life reported most frequently (52.8 %). 47.3 % reported no adverse impact of the pandemic on
implementing their usual coping strategies. Activities that respondents most commonly reported the same or
greater level of engagement in compared to before the pandemic were avoiding known mood triggers (82.3 %),
relaxation techniques (78.8 %) and the ability to maintain set routines (69.4 %).
Limitations: Responder bias may be present and experiences during the pandemic are likely to differ among other
clinical and research mood disorders cohorts.
Conclusions: Our findings may help to explain why longitudinal studies have not found a worsening of mental
health symptoms during the COVID-19 pandemic. Identifying potential facilitators to maintaining mental health
have wider applicability, and may help to inform future evidence-based psychoeducation and self-management
