A population survey of prevalence rates of antenatal depression in the Irish obstetric services using the Edinburgh Postnatal Depression Scale (EPDS).

Ireland has the second-highest birth rate in Europe and poorly developed perinatal psychiatry services. There are no screening services for antenatal depression and no data available on prevalence rates of depression among women attending the Irish obstetric services. The aim of this study was to assess the prevalence rates of depression during pregnancy in a population sample in Ireland using the Edinburgh Postnatal Depression Scale (EPDS) as a screening tool. Pregnant women during all stages of pregnancy were recruited from five maternity hospitals throughout the Republic of Ireland. Approximately 5000 EPDS questionnaires were collected. Information on the participant's age, gestational week, gravidity, parity, and level of education attained was also collected. A score of > 12 was used as a measure of probable depression. Overall, 15.8% of pregnant women scored > 12 in the EPDS. There was a significant association between gestational week and rates of depression, with increasing rates occurring with advancing pregnancy (p < 0.001). Overall, higher socioeconomic groups were over-represented in the sample although we replicated the well-established findings of higher EPDS scores in women with lower educational attainment (p < 0.005). This study demonstrates that prevalence rates of probable antenatal depression are high among women attending the obstetric services in Ireland and highlight the importance of increasing awareness of antenatal depression. These high rates of antenatal depression may be related to certain conditions that are specific to an Irish setting: the absence of screening for depression in the context of grossly under-resourced perinatal psychiatry services. These findings provide indirect confirmatory evidence for the need for streamlined mental health services within reproductive health services.

Postpartum Psychosis: A Proposed Treatment Algorithm.

Background: Postpartum psychosis (PPP) is a psychiatric emergency that generally warrants acute inpatient care. PPP is marked by the sudden onset of affective and psychotic symptoms with a rapid deterioration in mental state. Evidence suggests that PPP is a discrete disorder on the bipolar disorder spectrum with a distinct treatment profile and prognosis. Methods: We conducted a PubMed database search for various terms involving PPP and its treatment and included peer-reviewed articles published in English. Objective: To provide a treatment algorithm for the management of PPP based on available evidence. Results: Pharmacological therapy is the mainstay of PPP management in the acute phase. Evidence points to a combination of antipsychotics and lithium in the acute treatment of PPP. Electroconvulsive therapy can offer a rapid treatment response where required. Lithium appears to have the best evidence for relapse prevention and prophylaxis in PPP. Psychoeducation is essential and psychosocial interventions used in bipolar disorder may be effective in PPP. Conclusion: Early detection and prompt treatment with antipsychotics and lithium, followed by maintenance treatment with lithium, is associated with a favourable prognosis in PPP.Reprinted from J Psychopharmacol 2023; 37:960-970, with permission from Sage Journals.

Postpartum depression: A role for psychedelics?

BACKGROUND: Postpartum depression (PPD) is a major public health concern and has, at its core, a sense of maternal 'disconnection' - from the self, the infant, and the support system. While PPD bears similarities with MDD, there is increasing evidence for its distinct nature, especially with the unique aspect of the mother-infant relationship. Current treatment modalities for PPD, largely based on those used in major depressive disorder (MDD), have low remission rates with emerging evidence for treatment resistance. It is, therefore, necessary to explore alternative avenues of treatment for PPD. OBJECTIVE: In this narrative review, we outline the potential therapeutic rationale for serotonergic psychedelics in the treatment of PPD, and highlight safety and pragmatic considerations for the use of psychedelics in the postpartum period. METHODS: We examined the available evidence for the treatment of PPD and the evidence for psychedelics in the treatment of MDD. We explored safety considerations in the use of psychedelics in the postpartum period. RESULTS: There is increasing evidence for safety, and encouraging signals for efficacy, of psilocybin in the treatment of MDD. Psilocybin has been shown to catalyse a sense of 'reconnection' in participants with MDD. This effect in PPD, by fostering a sense of 'reconnection' for the mother, may allow for improved mood and maternal sensitivity towards the infant, which can positively impact maternal role gratification and the mother-infant relationship. CONCLUSION: Psychedelic assisted therapy in PPD may have a positive effect on the mother-infant dyad and warrants further examination.

Antenatal depression and maternal infant directed speech during the first postnatal year.

BACKGROUND: Antenatal depression is emerging as a potential risk factor for lower maternal sensitivity during postnatal mother-infant interactions. The present study investigated the relationship between both antenatal and postnatal depression and features of infant directed speech, a key indicator of maternal sensitivity during the first postnatal year. METHODS: Pregnant women with either a clinical diagnosis of Major Depressive disorder (MDD; n = 20) or a history of MDD (n = 26) and a control group (n = 34) were recruited to the study and followed up at two, six and twelve months postpartum. A free-play mother-infant interaction was recorded at each time-point and the lexical and syntactic complexity of the mothers' speech was measured from the transcript. RESULTS: No significant group differences were observed at either two, six or twelve months. However, mediation analyses indicated that antenatal depression was indirectly associated with maternal syntactic complexity at two and twelve months through concurrent maternal depression scores. LIMITATIONS: The findings of this study are limited by its small sample size. The sample also comprised predominantly well-resourced women which limits the generalisability of the findings to wider or less advantaged populations. CONCLUSIONS: This study contributes to the emerging evidence base concerning the impact of antenatal depression and postnatal depression on early mother-infant interactive behaviour, specifically infant-directed speech. These findings further highlight the importance of identifying women with antenatal depression in order to support them to engage in therapeutic interventions at the earliest possible opportunity.

The hypothalamic-pituitary-adrenal axis in the perinatal period: Its relationship with major depressive disorder and early life adversity.

Objectives: Effects of major depressive disorder and early life adversity (ELA) on the maternal HPA axis in the perinatal period were examined.Methods: Four groups of women (n = 127) were recruited, with the perinatal groups being compared during pregnancy (Preg) and at two months postpartum (PP) - [1] Depressed during pregnancy (Depressed-Preg/PP), [2] Prior history of depression but euthymic during pregnancy (History-Preg/PP), [3] Healthy pregnant women (Control-Preg/PP), and [4] Healthy non-pregnant women (Non-pregnant Control). Serial saliva samples were collected over the course of a day and waking and evening cortisol, total cortisol output and the cortisol awakening response were examined.Results: There were no HPA axis differences among the three groups during pregnancy. A history of ELA, regardless of comorbid depression, was associated with higher evening cortisol levels during pregnancy (p = 0.015). Women in the Depressed-PP group had had higher evening cortisol levels compared to the History-PP group (p < 0.017).Conclusions: Evening cortisol measures are a potential marker for both ELA and depression, with higher levels during pregnancy being associated with ELA and higher levels postpartum being associated with antenatal depression.

Antenatal depression and the impact on infant cognitive, language and motor development at six and twelve months postpartum.

BACKGROUND: Antenatal depression is associated with adverse social-emotional and behavioural outcomes during childhood but there has been little investigation of the impact on infant neurodevelopment during the first postnatal year. AIMS: The aim of this study was to assess the impact of depression during pregnancy on infant cognitive, language and motor development at six and twelve months using a prospective longitudinal study design. PARTICIPANTS: Pregnant women with a clinical diagnosis of Major Depressive Disorder (MDD; n = 23), a history of MDD (n = 34) and a control group (n = 43) and their infants. OUTCOME MEASURES: MDD was measured during pregnancy and both maternal depression and infant cognitive, language and motor development were measured at six and twelve months postpartum. RESULTS: At six months, infants in the MDD group had lower motor development scores (M = 95.48, SD = 11.87) compared with controls (M = 99.97, SD = 10.64, p = .026) after controlling for maternal concurrent depression scores. At twelve months, infants in the MDD group had lower language scores (M = 87.33, SD = 10.54) compared with controls (M = 95.06, SD = 11.78, p = .037) which attenuated after controlling for maternal concurrent depression. CONCLUSIONS: These data contribute to the growing literature investigating the impact of antenatal depression on infant cognitive, language and motor development within the first postnatal year. The association between maternal depression and lower infant motor scores highlights the importance of early intervention for both mothers and infants in situations where maternal well-being is at risk.

DNA methylation differences at the glucocorticoid receptor gene in depression are related to functional alterations in hypothalamic-pituitary-adrenal axis activity and to early life emotional abuse.

Depression is associated with alterations in hypothalamic-pituitary-adrenal (HPA) axis activity. A proposed mechanism to explain these alterations are changes in DNA methylation levels, secondary to early life adversity (ELA), at stress-related genes. Two gene regions that have been implicated in the literature, the glucocorticoid receptor gene (NR3C1) exon 1F and the FKBP5 gene intron 7 were examined in 67 individuals (33 depressed patients and 34 controls). We investigated whether cortisol concentrations, evaluated in 25 depressed patients and 20 controls, and measures of ELA were associated with the degree of methylation at these candidate gene regions. Mean NR3C1 exon 1F DNA methylation levels were significantly increased in the depressed cohort and the degree of methylation was found to be positively associated with morning cortisol concentrations. DNA methylation levels at specific CG sites within the NR3C1 exon 1F were related to childhood emotional abuse severity. DNA methylation at CG38 was related to both HPA axis and childhood emotional abuse measures in the depressed group. No FKBP5 differences were revealed. Our findings suggest that hypermethylation at the NR3C1 exon 1F may occur in depression. This locus-specific epigenetic change is associated with higher basal HPA axis activity, possibly reflecting acquired glucocorticoid receptor resistance.
